๐ ved(1L) ๐ โ Schilyยดs USER COMMANDS, but make it bestie-friendly
okay so welcome to VED(1L), the manual page for your new favorite screen editor โจ we're doing this in parts, so buckle up buttercup ๐
โจ NAME โจ
ved โ the visual editor, aka the screen-oriented one, aka it takes over your whole terminal and looks cute doing it ๐
๐ธ SYNOPSIS ๐ธ
ved [ options ] [ filename ... ]
ved-e [ options ] [ filename ... ]
ved-w [ options ] [ filename ... ]
๐ฆ DESCRIPTION ๐ฆ
So Ved โ short for visual editor โ is a small and very fast screen-oriented editor, and its whole user-interface vibe sits somewhere between vi and emacs. It's powerful, it's easy to learn (fr fr, no cap), it has no limitations on line length and no limitations on the type of characters that may appear in a file. It has almost no limitations on file size either, and it supports editing of large files (like, files > 2 GB large ๐) if the OS has large file support.
Here's the tea on how to use it:
- To edit a file for the first time, just call
vedand specify the name of the file you want to edit. - If you edit a file for the second time,
vedwill place you at the same cursor position that was used the last time you edited this file. It remembers. It cares. ๐ซถ - If you don't specify a file name at all,
vedwill assume you want to edit the last file you edited in your current directory. And the cursor position in this case, again, will be the same as with the last editing session for this file.
Calling ved-e is literally the same as calling:
ved -e
and calling ved-w is the same as calling:
ved maxlinelen=78.
(yes, that trailing period is part of it, don't come for me ๐)
Ved is using the termcap data base so it's independent from the terminal type. See the Termcap section below.
๐ OPTIONS ๐
-v,-vhelp,-vedhelpโ your editing session starts with the on-line help up on screen. It's done in read-only mode, so you can look but you can't touch ๐-r,-readonlyโ in this mode you may edit the content of the edit buffer, but you are not allowed to write back the modified buffer by using the quit command of the editor. And if you use this option more than once, the readonly value gets incremented. Use-readonlytwice or more and you're not allowed to write the file back even in quit force mode. That's the strictest vibe check possible ๐ซb=#,buffers=#โ by defaultveduses10in-core buffers to edit the file, and each in-core buffer takes8 kB(the actual values compiled intovedmay be retrieved by callingved -help). Files that are bigger than the total amount of in-core buffer space get edited by using the swap file ofved. If you specify a number higher than the default, you'll need more space in memory, but the speed will slightly increase โก-n,-nobakโ don't createfilename.bakwhen writing back the file using the quit command of the editor. > Heads up bestie: if you use this option you will still break hard links. If you like to write into the original file, you should better use theWcommand when you quitved.-nolockโ don't try to use record locking to tell other editors that a file is being edited or just being written to. This option may help if NFS record locking bugs would otherwise cause an edit session to hang in thefcntl()lock request ๐ญ-e,-edtmpโ don't write to the file.vedtmp.uid. (vednormally stores the names and cursor positions of files in.vedtmp.uid.)-raw8โ do not expand characters with the MSB set. Note thatvedwill by default not expand characters with the MSB set that seem to be printable, e.g. when the terminal is in 8-bit mode. If this option is used, the expansion of 8-bit characters is turned off unconditionally. If the terminal is in 7-bit mode, this may result in incorrectly displayed characters ๐-d,-dosโ map new-line to carriage-return new-line and hide carriage-return characters that are directly followed by a new-line. If you type in a new line character, this results in inserting a carriage-return new-line pair. But sincevedis acting binary transparently, reading in files that don't follow DOS newline conventions will not cause the content of the file to be automatically converted to use DOS new-lines. Also: if-nodoshas not been specified,vedtries to auto-detect whether a file needs DOS (CR/LF to LF) mapping or not ๐-nodosโ do not map new-line to carriage-return new-line and hide carriage-return characters that are directly followed by a new-line. If-nodoshas been specified, auto-detection of DOS files is disabled and files will always be edited in POSIX line mode ๐งs=search stringโ start the editing session with a search for searchstr ๐-t,-tagโ first filename is really a ctag.wrapmargin=#โ set the default wrap margin to#. The wrap margin is counted from the end of a terminal line ๐maxlinelen=#โ set the max line length for autowrap to#. The behaviour is similar to thewrapmargin=option, butveddoes not use the maximum linelength from the current screen width โ it uses the fixed length#.-R,-Recoverโ recover session from the specified filename.vedgenerates a filevedP.xxxxin the/var/tmpdirectory or in the directory named by theVED_TMPDIRenvironment, and all action of the user is stored in it during the session. This file must be used as the only argument tovedwhen running a recover session ๐ฉน
๐ THE STATUS LINE ๐
The first (top) line of the screen is reserved for ved status information. It's divided into five fields, and here's what they are, left to right:
- Info/Input โ the first field shows informational messages and fetches the extra input that some commands need. Every command that needs confirmation requests input from this field. Its size defaults to
1/4thof the length of a line, and it may use more space if needed. - Number โ the second field holds the current multiplier for the next command. This multiplier gets reset to
1after each command, and you can set it to a different value yourself (see the NUMBERS section below). It's referred to as number in the following text. Its size is fixed to1/8thof the length of a line. If the actual number doesn't fit in that space, the textBIGis printed instead ๐ - Takebuffer โ the third field holds the name of the actual take buffer used for cut and paste operations. The name of this buffer defaults to
defaulton startup, and it may be changed by the user. Its size is fixed to1/4thof the length of a line. - Filename โ the fourth field usually displays the current filename. Its size defaults to
1/4thof the length of a line. It may use up more space if needed and no error text is displayed, and it may be hidden for some time if a long error message is displayed ๐ - Error text โ the fifth field is where all error messages and warnings show up. Its size defaults to
1/4thof the length of a line, and if needed it may use the space of the filename field too.
๐ BASIC COMMAND FORMAT ๐
Ved does not distinguish between command mode and insert mode. Unless prefixed by commands that need arguments, all non control characters are treated as input (which is inserted into the file buffer). So you just type, bestie โจ
All basic ved commands are control characters or escape sequences. To enter a control character, use the control key like the shift key together with a character key; to enter an escape sequence, press the <ESC> key followed by another key.
In the following description, ^ represents the control key and <ESC> the escape key (which is identical to pressing ^[). <ALT> has a similar usage as <ESC> but a different meaning in ved, and represents the combination ^]. The combination ^char is a single keystroke, while <ESC>char or <ALT>char are two keystrokes. If the command takes an argument, the argument is terminated with a carriage return <CR>.
A command may be modified in five ways:
- Escape commands โ typing the
<ESC>key (or^[) before the command will modify it to an alternate form, usually a related function. - Alt commands โ typing the ALT key (
^]) before the command inserts a mark (with a few exceptions) in the text, usually at the current cursor position, and then executes the normal command. You can precede any command that moves the cursor with the ALT key, andvedsets the mark before moving the cursor ๐ฏ - Alt Escape commands โ typing ALT (
^]) and ESC (^[) before the command inserts a mark (with a few exceptions) in the text, usually at the current cursor position, and then executes the ESC command. You can precede any ESC command that moves the cursor with the ALT key andvedsets the mark before moving the cursor. Typing ESC followed by ALT yields the same effect ๐ซ - Extended commands โ typing a
^Xbefore another command enters the extended mode. The extended mode just enters another level of commands. These extended commands have their own list of basic, ESC, ALT and ALT/ESC command tables. - Multiplied execution โ numbers that are entered by typing
<ESC>#<CR>(#represents a positive number) will set the multiplier to that number and display it in the status line ofved. If a number greater than one is entered before a command, that command is usually repeated number times. Exceptions are some cursor movement commands, where different functions will be executed number times instead of repeating the visible basic functionality of the command ๐
๐ CURSOR MOVEMENT ๐
Like every editor, ved has a typing point called the cursor, which is indicated by the (in most cases) flashing bar or box on your screen, depending on your terminal/window type. The cursor indicates the point within the file buffer where the typed characters are going to โ it's literally your current place in the file buffer ๐ The commands that move the cursor within the file buffer are explained in this section.

(yes bestie, each row says the pair twice โ that's just how the table's laid out ๐ )
Also quick note so nothing confuses you: "para" is used as an abbreviation for "paragraph" in that table, and that's purely so the thing fits inside the standard line width. iykyk ๐

<ALT><ESC>^Pfirst inserts the mark, then moves the cursor up that number of paragraphs prior to its current position.
- If number is greater than one,
โจ INSERTION/DELETION โจ
Okay bestie, this is the glow-up where text appears and disappears. Every insertion happens exactly where the visible cursor is โ like, that's the spot, periodt. ๐
All deletions get saved in two buffers: the forward delete buffer holds text deleted with forward delete commands, and the backwards delete buffer holds text deleted with backward delete commands. The characters in the backward delete buffer are saved in reverse order so they can be reinserted in the correct order. As long as you don't move the cursor and start deleting new text in either direction, the content of both the forward and the backwards delete buffer may be reinserted with the undo delete command. This lets you move text by deleting it and reinserting it after you move the cursor to another position in the file. Cute, right? ๐
๐ธ Insertion/Deletion command overview ๐ธ
Here's the cheat sheet. Columns are Key, CTRL, ESC CTRL, ALT (set mark first), and ALT ESC (set mark first).

๐ Insertion/Deletion commands in detail ๐
^Dโ erases the character at the cursor position.
If number is greater than one, ^D erases that number of characters to the right of the cursor.
<ESC>^Dโ erases the next word. A word is defined from the current cursor position to the next blank or carriage return.
If number is greater than one, <ESC>^D erases that number of words to the right of the cursor.
^Iโ inserts aTABcharacter.
If number is greater than one, ^I inserts that number of TAB characters.
<ALT>^Iโ inserts the mark at the current cursor position before inserting aTABcharacter.
If number is greater than one, <ALT>^I inserts the mark, then inserts that number of TAB characters.
^Jโ inserts a new line at the current cursor position and moves the cursor to the beginning of the next line.
If number is greater than one, ^J inserts that number of new lines.
^Kโ erases the current line. If the cursor is located at the beginning of the line, the entire line is erased, including the carriage return at the end of the line. If the cursor is located between the beginning and end of the line, everything right of the cursor is erased, including the carriage return at the end of the line. You can use^Kto erase blank lines.
If number is greater than one, ^K erases that number of lines from the current cursor position.
<ESC>^Kโ erases from the current cursor position to the end of the paragraph. The end of a paragraph is indicated by two successive carriage returns--one at the end of the last line and one on the blank line that follows the paragraph.
If number is greater than one, <ESC>^K erases that number of paragraphs.
<ALT>^Kโ erases text between the mark and the current cursor position. For instance, if the mark is in the middle of the file and the cursor is at the end, the last half of the file will be erased.^Mโ inserts a new line at the current cursor position and moves the cursor to the beginning of the next line.
If number is greater than one, ^M inserts that number of new lines.
^Oโ inserts a new line at the current cursor position, but does not move the cursor. Any text to the right of the cursor moves down to start a new line.
If number is greater than one, ^O inserts that number of new lines without moving the cursor.
<ALT>^Oโ inserts a new line without moving the cursor. It inserts the mark at the beginning of the next (new) line.
If number is greater than one, <ALT>^O inserts that number of new lines without moving the cursor. It inserts the mark after the last new line.
^DELETEโ erases the character to the left of the cursor. This acts the same as using theDELETEkey alone.
If number is greater than one, ^DELETE erases that number of characters to the left of the cursor.
<ESC>^DELETEโ erases the word to the left of the cursor. This acts the same as using^DELETE.
If number is greater than one, <ESC>^DELETE erases that number of words to the left of the cursor.
^_โ reinserts the last deletion. The content of the forward and backward delete buffer is cleared after reinserting the deleted text.<ALT>^_โ erases the mark.
๐ CUT/PASTE ๐
These commands deal with the 'take' buffers. You can have up to 32 take buffers, each named as you choose when you use it for the first time. The name appears on the status (top) line of the terminal screen following \:. The default take buffer is "default". Slay. ๐ซถ

๐ฆ Cut/Paste commands in detail ๐ฆ
^Tโ removes a line from the file buffer and puts it in the current take buffer. The line is defined from the current cursor position to the next carriage return.
If number is greater than one, ^T removes that number of lines from the file buffer and puts them in the current take buffer.
<ESC>^Tโ removes a paragraph from the file buffer and puts it in the current take buffer. A paragraph is defined from the current cursor position to two successive carriage returns--one at the end of the last line and one on the blank line that follows the paragraph.
If number is greater than one, <ESC>^T removes that number of paragraphs from the file buffer and puts them in the current take buffer.
<ALT>^Tโ removes the selection (what lies between the mark and the cursor) and puts it in the current take buffer.^Vโ pastes the contents of the current take buffer into the file at the current cursor position. The take buffer will still contain a copy of the text.<ESC>^Vโ pastes and clears the contents of the current take buffer into the file at the current cursor position. The take buffer will be empty.<ALT>^Vโ replaces the selection (what lies between the mark and the cursor) with whatever is in the current take buffer. The old content of the selection is not saved in any way. The take buffer will still contain a copy of the text.<ALT><ESC>^Vโ replaces the selection (what lies between the mark and the cursor) with whatever is in the current take buffer and clears the take buffer. The old content of the selection is not saved in any way. The take buffer will be empty.^Yโ removes a character from the file buffer and puts it in the current take buffer. The character at the current cursor position is the one taken.
If number is greater than one, ^Y takes that number of characters and puts them in the current buffer.
<ESC>^Yโ removes a word from the file buffer and puts it in the current take buffer. A word consists of any characters from the current cursor position up to the next blank or carriage return.
If number is greater than one, <ESC>^Y takes that number of words and puts them in the current buffer.
^\โ changes the current take buffer.
On the information line you will see the Take Buffer: prompt. Type a take buffer name and press the RETURN key.
If you type a new name, a new take buffer is created. If you type a name you have already used during the current editing session, you can reuse that take buffer. The take buffer name is always displayed on the information line.
<ESC>^\โ clears any text out of the current take buffer. On the information line you will see theBuffer clearedmessage.
๐ SEARCH ๐
okay so the search commands go hunting for whatever text you type into the file buffer, and they may park your cursor right on the matching text ๐
here's the tea: if your pattern has pattern-matching meta characters in it, the pattern matcher gets used (unless you've flipped on no magic mode โ see the set command below), and if there are literally no meta characters, it just does a plain simple search ๐

Search commands in detail ๐ฆ
^Rโ searches forward in a file for the specified text string.
on the information line you'll see the +Search: prompt. type the string you wanna find. if that string exists between where your cursor is sitting right now and the end of the file, ved moves the cursor to that spot โจ if ved can't find the string, the cursor does not move and you will hear a beep ๐ญ
if number is greater than one, ^R finds that numbered occurrence of the string.
<ESC>^Rโ searches backwards in a file for the specified text string.
on the information line you'll see the -Search: prompt. type the string you wanna find. if the string exists between the cursor's current position and the beginning of the file, ved moves the cursor there ๐ if ved can't find the string, the cursor does not move and you will hear a beep ๐ญ
if number is greater than one, <ESC>^R finds that numbered occurrence of the string.
<ALT>^Rโ searches forward in a file for the specified text string.
on the information line you'll see the +Search: prompt. type the string you want to find. when (and if) it's found, the mark is inserted at the beginning of the string and the cursor moves to the end of the string โ at that point the string is considered selected ๐ if ved can't find the string, the cursor does not move, no mark is inserted, and you will hear a beep ๐
if number is greater than one, <ALT>^R finds that numbered occurrence of the string.
<ALT><ESC>^Rโ searches backwards in a file for the specified text string.
on the information line you'll see the -Search: prompt. type the string you want to find. when found, the mark is inserted at the beginning of the search string and the cursor moves to the end of the string โ the string is then considered selected ๐ธ if ved can't find the string, the cursor does not move, no mark is inserted, and you will hear a beep ๐
if number is greater than one, <ALT><ESC>^R finds that numbered occurrence of the string.

๐พ EXITING/SAVING ๐พ
these commands are all about bouncing out of ved and saving the current version of the edited text into a file, bestie ๐ซถ
^Cโ theQUITcommand ends the editing session.
on the information line you'll see the QUITTING. PUT EDITS? (Y/W/N/F/!) prompt.
type Y if you want to save the changes made during this editing session by creating a backup file and creating a new file that holds the modified content. the backup process goes down like this:
the current backup file (if there is one) (called filename.bak) is deleted, the current file is renamed to filename.bak, and a version of the file containing the latest changes becomes filename. if there is no filename.bak, filename becomes filename.bak ๐
type W if you want to save the changes made during this editing session by directly writing the new content into the old file.
type F if you want to forcibly save the changes made during this editing session. this command works similar to the Y command, but ved will ignore the state of the -readonly flag and the access rights of the file ๐ the latter will allow you to write into files without write permissions if you are super user. for exceptions on this rule, see description of the -readonly flag.
type ! if you want to forcibly save the changes made during this editing session by directly writing the new content into the old file.
type N if you want to end the session but don't want to save the changes.
if you don't want to end the session, type anything except Y, W, F, ! or N ๐
heads up: if the file has been locked before by another edit session or if the file has been modified more recently than the copy that has been used for the current session, you will not be allowed to save the file ๐ค use the force commands (For!) or write back using a different file name.
<ESC>^Cโ theBACKUPcommand backs up the current file.
on the information line you'll see the BACKUP?(Y/W/N/F/!) prompt.
if you enter one of the expected answers (Y, W, ! or N) the same actions as with the QUIT command are performed, except that the controls stay inside ved after the backup command has completed โจ
^X^Hโ calls on-line help.
on the information line you'll see the HELP(Y?) prompt. to continue editing (and abort this command), type N. to see the help file, type Y ๐
note that this command may not work in case that the terminal in use outputs a backspace when typing the DEL key. in such a case, it is appropriate to type: ESC : vhelp
^X^Zโ suspends the current editing session.
on the information line you'll see the SUSPENDING. PUT EDITS? (Y/W/N/F/!) prompt.
type Y if you want the file to be backuped and updated before suspending ved. see the QUIT command for a description of the backup process ๐
type W if you want the the file to be updated in place before suspending ved.
type F if you want file to be forcibly updated before suspending ved. this command works similar to the Y command, but ved will ignore the state of the -readonly flag and the access rights of the file ๐ the latter will allow you to write into files without write permissions if you are super user. for exceptions on this rule, see description of the -readonly flag.
type ! if you want file to be forcibly updated in place before suspending ved.
type N if you want to suspend ved but don't want to save the changes before.
if you don't want to suspend ved, type anything except Y, W, F, ! or N ๐
same warning as before, no cap: if the file has been locked before by another edit session or if the file has been modified more recently than the copy that has been used for the current session, you will not be allowed to save the file ๐ค use the force commands (For!) or write back using a different file name.
when you're ready to continue editing, use the fg or resume command of your shell. you'll return to the editing session, and the cursor will be in the same place it was when you suspended the session, regardless of whether or not you saved your edits ๐โจ
โจ FILE COMMANDS โจ
^Gโ lets you insert another file right at the current cursor position. ๐
On the information line you'll see the Get from: prompt, bestie. Type a file name and hit the RETURN key.
You can pull files in from the current working directory or from other directories (as long as the path name is actually valid, obviously). The path name gets filename-globbed by your shell โ so like, wild cards work as long as they expand to exactly one filename. Slay. โจ
<ESC>^Gโ exits the current file and hops into another file. ๐ฆ
On the information line you'll see the Change to: prompt. Type the name of the file you wanna edit and press RETURN.
If the old file was modified, you'll get the CHANGING TO: filename. PUT EDITS?(Y/W/N/F/!) prompt โ this is asking whether you want to save and backup the edits in the current file. Literally the vibes check of the whole operation:
- Type
Yif you want the file to be backuped and updated before changing the file. See theQUITcommand for a description of the backup process. - Type
Wif you want the the file to be updated in place before changing the file. - Type
Fif you want file to be forcibly updated before changing the file. This command works similar to theYcommand, butvedwill ignore the state of the-readonlyflag and the access rights of the file. The latter will allow you to write into files without write permissions if you are super user. For exceptions on this rule, see description of the-readonlyflag. - Type
!if you want file to be forcibly updated in place before changing the file. - Type
Nif you want to change the file but don't want to save the changes before.
If you don't want to change the edited file at all, type anything except Y, W, F, ! or N. ๐ซถ
Heads up, bestie: if the file has been locked before by another edit session, or if the file has been modified more recently than the copy that has been used for the current session, you will not be allowed to save the file. Use the force commands (For!) or write back using a different file name. No cap. ๐
^Wโ writes a copy of the file you're editing to the file you specify. ๐
On the information line you'll see the Write to: prompt. Type a file name and press RETURN. If the file exists, its contents are overwritten. If the file doesn't exist, it gets created. Fresh file, main character energy.
<ESC>^Wโ writes the contents of the current take buffer to the file you specify. ๐ธ
On the information line you'll see the \ to file: prompt. Type a file name and press RETURN. If the file exists, its contents are overwritten. If the file does not exist, it is created. The take buffer contents will remain intact โ nothing lost, we love that. ๐
<ALT>^Wโ writes a copy of the selection (what lies between the mark and the cursor) to the file you specify. โญ
On the information line you'll see the Sel to: prompt. Type a file name and press RETURN. If the file exists, its contents are overwritten. If the file does not exist, it is created.
๐ข NUMBERS ๐ข
<ESC>#<CR>โ to enter a multiplier that only works for the next command, type<ESC>, enter a number and then press the RETURN key. If you entered a number by mistake, simply enter<ESC>1<CR>to reset the number to its default value. Easy undo, we stan. ๐^Uโ multipliesnumberby the multiplier. The default multiplier is4. Each time you press^Unumberchanges to the next multiple of4(16,16,64, and so on). ๐<ESC>^Uโ changes the multiplier.
The default multiplier is 4. If you want to multiply number by a different value, use <ESC>^U. On the information line you'll see the Mult = prompt. Type a number and press the RETURN key. Custom math, iconic. ๐ง
๐ MISCELLANEOUS ๐
<ALT>^Gโ lets you edit your editing macro file called.vedmac(which lives in your$HOMEdirectory). It's the same as if you used^X^Xto execute a newvedand answeredNto the put question. When you're through editing.vedmac, press^Cto continue editing the file you were in when you issued the<ALT>^Gcommand; you'll be asked whether or not you want to put the edits from.vedmacbefore you return to the original file. ๐ซ<ALT>^Jโ moves the cursor to the mark. ๐
The current cursor position determines whether this is a forward or backward movement. For instance, if the mark is in the middle of the file and the cursor is at the beginning, its a forward movement; if the cursor is at the end, its a backward movement. Direction is giving โจjourneyโจ.
<ALT><ESC>^Jโ switches the cursor and the mark. ๐^Lโ redisplays the current screenful of text. This is useful after a message has been sent to your terminal which may have overwritten some of the text. Clean slate, we love a refresh. ๐ฆ<ESC>^Lโ adjusts the text displayed on the terminal screen so that the line the cursor is on becomes the optimum line on the screen. This usually is the center line of the display but it may be changed using the<ESC>:set optline # <CR>command. This may involve displaying different text, depending on where the cursor is when you use this command. Centering your fave line, iconic behavior. ๐<ALT>^Lโ Adjusts the current Line of the Cursor to be the first Line on Screen. ๐<ESC>^Mโ changes modes. ๐ฅ
On the information line you'll see the Mode?(ORV8) prompt. Type:
Dto enable or disable DOS mode.Vfor visible mode.Ofor overstrike mode.8to enable or disable raw8 mode.Rto reset back to default mode.<CR>to list the current mode settings.
If you type anything else, you will abort the command. Mood, honestly.
<ALT>^Mโ sets a mark at the current cursor position. ๐ซถ<ESC>nโ displays the next Page of file. โญ<ESC>pโ displays the previous Page of file. โญ<ALT><ESC>nโ Sets a Mark, then displays the next Page of file. ๐<ALT><ESC>pโ Sets a Mark, then displays the previous Page of file. ๐^Qโ unfreezes the screen which was frozen by pressing^S. ๐งโก๏ธ๐ฅ^Sโ freezes cursor and text movement on the screen. Use^Qto unfreeze it. โ๏ธ^X^Xโ lets you execute a shell command without terminating the editing session. ๐โจ
Control temporarily returns to the Command Interpreter while the command is executed, then you can continue editing. For instance, if you want to read another file into the one you're editing but can not remember the file name, you can execute an ls command to find its name. When you type ^X^X, you'll see the Execute: prompt on the information line. Type the command line and press the RETURN key. If the file was modified before you called ^X^X, you'll see the EXECUTING. PUT EDITS? (Y/W/N/F/!) prompt.

Fr fr bestie: if the file has been locked before by another edit session or if the file has been modified more recently than the copy that has been used for the current session, you will not be allowed to save the file. Use the force commands (For!) or write back using a different file name. ๐
In all cases, after returning from the command, the cursor will be on the same place as it was before typing ^X^X. Cursor stays put, main character never moves.
Note that if the shell command you want to execute requires the current file as an argument, you might need to update it. For instance, if you the file you are editing contains formatting commands that you want to test, you will need to update the file so that the version of the file you format and view is the most up-to-date one. ๐ญ
To abort the command while you can see the Execute: prompt, do not type a command; simply press the RETURN key. If you had started to type a command, use the DELETE key to erase it; the field following the prompt must be blank. To abort the command while you can see the EXECUTING. PUT EDITS? (Y/W/N/F/!) prompt, type anything except Y, W, F, ! N. Escape route secured. ๐
<ESC>^Xโ executes the contents of the current take buffer. ๐
You can type a shell command line in your file and then save it in a take buffer (using the ^T, <ESC>^T, ^Y or <ESC>^Y commands). Literally writing your own destiny.
When you type <ESC>^X, you'll see the EXECUTING. PUT EDITS? (Y/W/N/F/!) prompt on the information line.

and bestie, real talk: if the file got locked earlier by another edit session, or if the file's been modified more recently than the copy your current session has been using, ved is gonna straight up not let you save. ๐ญ use the force commands (F or !) or write back under a different file name. those are the moves. ๐

and again, because it matters: if the file has been locked before by another edit session, or if the file has been modified more recently than the copy that's been used for the current session, you will not be allowed to save. use the force commands (F or !) or write back using a different file name. no cap. ๐จ

๐ COLON COMMANDS ๐
colon commands are introduced via <ESC>: โ the command then gets entered on the (top) status line of ved. very main character of them. โจ
the colon commands are:
backupโ backup the current file. this command is the same as when<ESC>^Cis entered. it may be needed if for some reason it is not possible to enter the interrupt character of the terminal driver. ๐ซถbindโ print the current command binding for ved. later versions of ved may allow modification of the binding with this command. (future tea โ)helpโ print online help for the available colon commands. ๐งmacro macro bodyโ set up a temporary macro that may be executed via<ESC>*.mapmap from-string to-stringโ the first form lists all currently active mappings, the second form sets up a new mapping. ๐บ๏ธnextโ switch to next file in the file list. this command may only be used if ved has been called with more than one file argument. ๐ฏprevโ switch to previous file in the file list. same rule, bestie: this command may only be used if ved has been called with more than one file argument.quitโ quit ved. this command is the same as when^Cis entered. it may be needed if for some reason it is not possible to enter the interrupt character of the terminal driver.setset set-variable set-argsโ the first form lists the current settings of ved, the second form sets a specific property of ved. the variables that may be modified via thesetcommand are:autoindentโ if set, ved activates the auto indent mode. subsequent lines will be automatically indented with the same indent as the previous line. switch off with<ESC>:set noautoindent. โจlinelen new-linelenโ set the linelength that is used as base for screen updates. this linelength usually is retrieved from the terminal driver but may be modified manually.magicโ switch to magic mode for pattern matching (this is the default when ved has been started). if in magic mode, matching is done using regular expression pattern matching. this mode may be switched off with<ESC>:set nomagic. if magic mode is turned off, matching is done without using regular expression matching, even if the pattern contains magic characters for pattern matching. ๐ชmarkwrapโ mark wrapped lines with a\character at the end of a visible terminal line (this is the default when ved has been started). this mode may be switched off with<ESC>:set nomarkwrap.optline opt-lineโ set the optimal line. this is the line (counted from the top of the terminal) where the cursor is adjusted to when ved does scrolling. it is set by default to the half of the number of lines of the terminal. ๐ฏpmargin page-marginโ set the distance you need to have between the cursor and the upper or lower border of the terminal. if you cross this border, ved will start to scroll and adjust the cursor to the optimal line. it is set by default to0and allows one to place the cursor to any visible line on the screen.psize page-sizeโ set the pagesize that is used as base for screen updates. this pagesize usually is retrieved from the terminal driver but may be modified manually.tabstop tab-widthโ set the size of a visible tab character. this width is set to8by default.taglength tag-len-valueโ set the number of characters that are used to compare a tag name with a tag label in the tags file. if it is set to0(the default), ved compares the complete tag length.tags tag-file-listโ set the list of files that is searched when looking for a tag data base. the tag file list is separated by blanks and by default set to
tags .. /usr/lib/tags
this means that ved will first look for a file tags in the current directory, then search up for (directory by directory until the root directory is reached) a file tags, and last it will look for a file /usr/lib/tags. ๐๏ธ
wrapmargin wrap-marginโ ifwrapmaginis set, ved will activate the auto-warp mode. in auto-wrap mode, ved will automatically insert a newline before a word if the cursor is less thanwrap-maginfrom the right terminal border.

substitute /old/new/โ substitute pattern old by new. the pattern new may contain an&for the old string. ๐tag tag-nameโ goto tag named tag-name. see the FILES section for more information on the tag file. ๐ท๏ธvhelpโ edit the online help file. this is the same as callingved -vhelp. ๐
๐ MACROS ๐
Okay bestie, macros in ved are literally your little combo moves โ a mix of ved basic commands and input text. To make one, edit the file .vedmac in your home directory. You can do that by either explicitly typing ved ~/.vedmac or by using the built-in ved command <ALT>^G. ๐
The file ~/.vedmac contains a number of lines, and each one holds a macro definition like this:
L:/*^[74^M-*/: Comment Line
Each macro definition has three fields:
- name โ the name of the macro. In our case itโs simply
L, and the macro may be executed by typing<ESC>L. - function โ the implementation of the macro. In our case the function contains
/*^[74^M-*/and will draw a C-comment line that contains 74-chars as the body. - comment โ a comment for better understanding of the macro file. The comment is ignored.
The fields are separated by a colon. Macros may be combined to form new macros. They also may recursively call each other, and you may set number to a value greater than one to execute a macro more than once. There is currently no way to execute a macro in a conditional way. ๐ญ
๐ฆ MAPPINGS ๐ฆ
You may create mappings in ved that contain arbitrary character sequences. To create a mapping, edit the file .vedmap in your home directory.
The file ~/.vedmap contains a number of lines with the following structure:
map_from:map_to:comment
and holds a map definition like this:
\E[193z:^C:Quit Editor (L2)
Each map definition has three fields:
- map-from โ the from string (left-hand side) of the map. In our case the name is the sequence
\E[193z, which is the output of the L2 function key on a Sun keyboard. Every time you type the character sequence\E[193z, or hit a function key that emits this character sequence, it gets replaced by the replacement string before the input is read by ved. - map-to โ the replacement string (the right-hand side, aka the
tostring) of the macro. In our case the map expands to^Cand will quit ved. - comment โ a comment for better understanding of the map file. The comment is ignored.
If both map_from and map_to are empty, the related line is ignored by the mapper, so a line may contain:
::comment
A nul character in either map_from or map_to is currently not supported, but an empty map_to is interpreted as a nul character.
If a line has an empty map_to and the comment field starts with a * like this:
map_from::*comment
an existing mapping is removed. This permits ignoring unwanted mappings that have been set up from the TERMCAP entry. A typical use case for this feature is to avoid the mapping:
^H:^?:Key Backspace -> Delete Char
that is caused by the TERMCAP capability kb for terminals that create a backspace with the delete key.
Since the file $HOME/.vedmap is read in a sequential way, a later line with the same map_from may establish a different mapping.
The fields are separated by a colon. The text in the macro file is fed through tdecode() to allow the same escape sequences as you may have in the termcap file. โจ
๐ Input Mappings ๐
Ved maps input from the terminal into mapped text before it is interpreted by the editor. If a match is found on the input from the terminal, the related input text is directly replaced by its replacement string. A mapping may be prevented by typing the map quote character, which is the nul character (^@), directly before the matching text is entered. If this text is usually interpreted by ved, you first need to type the ved quoting character ^^. To be sure that you are able to literally enter some text, type ^^^@ (control up-arrow followed by Nul and the text). ๐ซถ
At startup, ved first tries to initialize the terminal setup using the variables HOME, TERM, TERMCAP and TERMPATH.
If TERM is not set, the mapper establishes standard mappings for the cursor keys assuming an ANSI-compatible terminal.
If TERM is set, the mapper establishes mappings for the following termcap capabilities:
kuโ Key cursor up, mapped to^P. The cursor is placed on the previous line.kdโ Key cursor down, mapped to^N. The cursor is placed on the next line.krโ Key cursor forward (right), mapped to^F. Move cursor one character to the right.klโ Key cursor left, mapped to^H. Move cursor one character to the left.khโ Key cursor -> Home, mapped to^A. The cursor is moved to the beginning of the current line.@7โ Key cursor -> End, mapped to^E. The cursor is moved to the end of the current line.kDโ Key Delete Character, mapped to\177(DEL). Erase one character to the left of the cursor.kbโ Key Backspace, mapped to\177(DEL). Erase one character to the left of the cursor.
Note that the Backspace Key is the larger key that is just above the Carriage Return Key. In former times, this key was called Delete and sent the\177(DEL) character. Since companies followed the design of the IBM PC keyboard layout, the related key usually sends\010. If you like to literally enter a backspace, type^^^@^H(control up-arrow followed by Nul followed by^H).
k1โ Key F1, mapped to Quit Editor (^C).k2โ Key F2, mapped to Top of File (^B).k3โ Key F3, mapped to Delete char (^D).k4โ Key F4, mapped to Delete line (^K).k5โ Key F5, mapped to Open line (^O).k6โ Key F6, mapped to Cut line (^T).k7โ Key F7, mapped to Paste (^V).k8โ Key F8, mapped to Change buffer (^).k9โ Key F9, mapped to Search down (^R).k;โ Key F10, mapped to Re search (^Z).F1โ Key F11, mapped to Get from (^G).F2โ Key F12, mapped to Write to (^W).kAโ Key Insert, mapped to Insert line (^A^O).kEโ Key Clear EOL, mapped to Delete to eol (^K).kLโ Key delete line, mapped to Delete line (^A^K).kNโ Key Page down, mapped to Page down (^[n).kPโ Key Page up, mapped to Page up (^[p).kSโ Key Clear EOS, mapped to Delete to end of screen (^[999999\015^K).
After the mappings from the termcap entry for the current terminal type have been established, ved tries to read the file $HOME/.vedmap to retrieve additional mappings.
๐ง Termcap ๐ง
The termcap data base is used to make ved independent from the terminal capabilities. Cursor key output is retrieved from the data base and mapped to the cursor movement commands of ved.
Ved uses a real termcap database, not terminfo. It is advised to have a suitable termcap database available, either in the file /etc/termcap or in the private file $HOME/.termcap with an entry for the terminal type that is currently in use. If an entry for the current terminal could not be found, ved uses a builtin terminal description for a minimal ansi compatible terminal.
The following variables are used by termcap:
HOMEโ to find the private files like$HOME/.termcap.TERMโ a name representing the type of the current terminal.TERMCAPโ this environment variable holds either a precompiled termcap entry or the pathname to be used to find a termcap database file. If it holds a precompiled entry that does not match theTERMenvironment, the termcap database is parsed as if theTERMCAPenvironment is not set. See section Parameter Substitution above for more information.TERMPATHโ ifTERMCAPis empty or not set, then theTERMPATHenvironment is scanned for pathnames of files that contain a termcap database. It holds a list of filenames separated by colons or spaces (i.e.,":"or" "). See section Parameter Substitution above for more information.
The following escape sequences are understood by the termcap implementation used by ved:
\\โ the literal character\.\Eโ the ESC character (ASCII 033).\eโ the ESC character (ASCII 033).\^โ the literal character^.\:โ the literal character:.\,โ the literal character,.\bโ the BACKSPACE character (ASCII 010).\fโ the FORMFEED character (ASCII 014).\lโ the LINEFEED character (ASCII 012).\nโ the NEWLINE character (ASCII 012).\rโ the CR character (ASCII 015).\sโ the SPACE character (ASCII 040).\tโ the TAB character (ASCII 007).\vโ the VERTICAL TAB character (ASCII 013).^cโ maps to control(c) for any appropriate c.^?โ the DEL character (ASCII 0177).\nnnโ maps to a character with the octal representation nnn with 1..3 octal digits.\0โ maps to ASCII 0200.^@โ maps to ASCII 00.
Mapping \0 to ASCII 0200 is required by the termcap documentation. A real nul character created from (^@) is currently neither supported by the upper layers of termcap, nor by the upper layers of the mapper. ๐
๐ธ ENVIRONMENT ๐ธ
okay bestie, these are the environment variables that make ved do its little environment-variable glam โจ
SHELLโ the shell to use for shell command escapes, file name globbing and similar. literally the go-to for shell stuff ๐HOMEโ used to find the private files~/.vedmac,~/.vedmapand~/.termcap. home sweet home, but make it config ๐TERMโ the type of terminal for which the output should be formatted. yes, the terminal vibe check ๐TERMCAPโ this environment variable holds either a precompiled termcap entry or the pathname to be used to find a termcap database file. if it holds a precompiled entry that does not match theTERMenvironment, the termcap database is parsed as if theTERMCAPenvironment is not set. no cap, that's the rule ๐ซถTERMPATHโ ifTERMCAPis empty, then theTERMPATHenvironment is scanned for pathnames of files that contain a termcap database. it holds a list of filenames separated by colons or spaces (i.e.,":"or" "). if theTERMPATHsymbol is not set, the files$HOME/.termcapand/etc/termcapare scanned in that order. iconic fallback behavior ๐BEEPโ the environment variableBEEPis used to suppress beeping when set tooff. this helps to usevedon a notebook in a meeting. yes bestie, silent-mode main character energy ๐คซPATHโ the environment variablePATHis used to find the on-line help file ofved. help me help you ๐SLASHโ if the environment variableSLASHis set to'off', no slashes are accepted in filenames. slash? not today, bestie ๐ซVED_FTMPDIRโ fast tmp directory. the directory where the ved swap filevedF.processidis stored. ifVED_FTMPDIRis not specified, the swap file will usually be stored in/tmp/. speedy little temp spot โกVED_TMPDIRโ general tmp directory. the directory where all ved tmp files except the swap file are stored. ifVED_FTMPDIRis not defined butVED_TMPDIRis defined, all ved tmp files will be placed into this directory. ifVED_TMPDIRis not specified, the other ved tmp files will usually be stored in/var/tmp/. the general admission tmp area ๐๏ธVED_STATISTICSโ if set and ved has been compiled with statistics support, ved will print statistic information at the end of a session. numbers girlies rise ๐
๐ FILES ๐
these are the files ved is obsessed with, fr fr ๐๏ธ
/etc/termcapโ the system's terminal capabilities database.~/.termcapโ the private terminal capabilities database.~/.vedmacโ contains private macro definitions.~/.vedmapโ contains private mappings.~/.vedtmp.uidโ contains the names of the files that have been edit from the current directory as well as the cursor position of the last visit. ved also keeps track of the last edited file.tagsโ this file contains a list of tags that tell ved where a definition for a tag may be found. tags may contain e.g. function names, macro names and typedefs. by default, ved looks for atagsfile in the current directory and if atagsfile is not found in the current directory, the directories above the current directory are searched until the root directory is reached. if atagsfile can be found in a directory closer to the root directory, ved will modify the file path from within thetagsfile to reflect the directory distance to thistagsfile. this property is unique to ved. ved acceptstagsfiles in the same notation asvi. tag treasure hunt, lowkey iconic ๐/tmp/vedF.processidโ the ved swap file./var/tmp/vedB.processidโ the ved backward delete buffer./var/tmp/vedD.processidโ the ved forward delete buffer./var/tmp/vedT.processidโ the current take buffer./var/tmp/vedTpastename.processidโ one file for every named take buffer./var/tmp/vedP.processidโ the ved crash recovery protocol buffer./var/tmp/vedX.processidโ the ved shell command execute buffer..../man/help/ved.helpโ the on-line help file is assumed to be in the same directory tree as the ved binary.

๐ NOTES ๐
unlike vi, ved is not based on a line editor. this avoids annoying bugs but may cause to irritate people who are used to work with vi. so likeโฆ different breed, same terminal energy ๐ญ
since ved uses a private implementation of the termcap terminal independent screen package, ved uses /etc/termcap even on systems that usually emulate termcap with terminfo. this allows us to use the portable terminal description on all operating systems. from my current point of view, ved will never switch towards terminfo. although terminfo provides more functionality than termcap, it tends to be non-portable between different platforms. while termcap allows one to have a private terminal database in the NFS mounted home directory, the same attempt tends to give problems with terminfo if a vendor did make private additions. because termcap explicitly names all capabilities, there are less problems with private additions; terminfo only uses an array index to identify a specific capability so this method only works if there is a global unique implementation. termcap said โname every capability,โ terminfo said โindex go brrrโ โ and ved is team termcap periodt ๐ง
if your platform does not provide an /etc/termcap file, or if your termcap database does not contain an entry for the terminal type you are using, the following command may be used to convert a terminfo entry into a termcap entry and to append it to your private termcap database
incofmp -C >> $HOME/.termcap
make sure that the TERM environment is assigned to the correct terminal type. no guessing, bestie โ
if the eighth bit of a character is "on", the tilde character ~ appears before characters, i.e., ~C. tiny tilde cameo ๐
