DIST(7)

💖 DIST(7) — Miscellaneous Information Manual 💖

okay bestie, gather round, because this is the intro page to dist, and it's lowkey the blueprint for making your software portable across every UNIX platform out there. sit with me. 🫶

🌈 DESCRIPTION 🌈

okay so the dist package is a whole set of tools whose entire job is to make building and maintaining portable software way less of a nightmare. there are four distinct parts in dist, and it's also meant to be used with two external products, both of which are publicly available: mailagent and patch. iconic lineup honestly.

The first component is the Configure script generator, which is a portability tool. It is automatically build up by metaconfig from your sources and a set of units. Ideally, the end-user receiving your source code will simply have to read your README file, run the Configure script (which is self-documented), and then run make. Your package should then build cleanly on every UNIX platform. 💅

The second component is the Makefile.SH generator, which is a generic configured Makefile, reusing some of the information figured out by Configure. Although you may write your own Makefile and then use makeSH to transform it into a Makefile.SH, it is better to write a generic Jmakefile description, which does not rely on a particular position within the source tree, and then use jmake to recursively build your Makefiles. no cap.

The third component is the package generator, which is used when it's time to build up the shell archives used to distribute your program. Although you may use your own archiving mechanism, the one included here knows about RCS files and will properly check out the lattest revisions, leaving your working files alone. The makedist program will also perform Copyright expansion, an useful feature when you share source files among more than one program, placed under distinct Copyright information. 🎀

The fourth and latest component is the patch generator, used to make updates of your sources, which can later be applied on the original distribution by using the patch program.

Before using any of the dist programs, you should probably identify your package by running the packinit program, which will create a .package file in the top-level directory of your package. do this first fr fr, it's the vibe check of your whole setup. ⭐

👑 COMMANDS 👑

The dist package implements the following commands (those tagged as library commands are to be found in the dist library and should not be made publicly available in everyone's path — like, keep those in the group chat, don't post them on main):

• bindex — builds the Index file (library).
• jmake — a Makefile.SH generator.
• jmkmf — bootstraps top-level Makefile.SH file.
• kitpost — posts distribution kits made by makedist.
• kitsend — sends distribution kits made by makedist.
• makeSH — wraps existing scripts into a .SH file.
• makedist — builds up distribution kits.
• makegloss — builds the Glossary file (library).
• manicheck — checks MANIFEST.new accuracy
• manifake — makes MANIFEST.new out of an existing MANIFEST.
• manilist — builds MANIFEST.new reports.
• metaconfig — a Configure script generator.
• metalint — a metaconfig unit consistency checker.
• metaxref — a metaconfig cross-reference builder.
• packinit — initializes a package (creates a .package file).
• pat — main patch generator.
• patbase — resets patch base to current version.
• patcil — checks new version in.
• patclean — remove working version of up-to-date files.
• patcol — checks file out.
• patdiff — builds (contextual) diffs for the patch.
• patftp — copies patches to public ftp directory.
• patindex — builds a patch index.
• patlog — handles ChangeLog file updates.
• patmake — puts diffs together into a patch.
• patnotify — notifies users that new patches have been released.
• patpost — posts patch to some newsgroup.
• patsend — mails patch to some people.
• patsnap — builds a release snapshot with files and RCS revisions.

🦋 PROFILE 🦋

Commands having a set of meaningful options (other than -h or -V) can also take arguments from the ~/.dist_profile file, or whatever file the DIST environment variable points to. Each line of the file is in the format:

profile-component: value

with shell-style comments (#) allowed provided they start the line. (so like, beginning of the line only, bestie, don't get cute mid-line 🌸)

Each command looks for a profile component entry matching its name and loads the value as if it were arguments specified on the command line. Those arguments precede any other argument specified manually, in case order is meaningful. ⚠️

Some commands may also be configured from within the profile, by setting a specific variable attached to the command by a profile entry looking like this:

cmdname-variable: value

For instance, assuming the variable c-files is recognized by the metaconfig program, its default value could be overwritten by this profile entry:

metaconfig-c-files: suitable value

Only the first - after the command name is part of the syntax, the other one used in the variable name is pure convention. Please refer to the manual page of each command for a list of valid profile variables which may be set. iykyk. 💜

🍓 FILES 🍓

• .MT — Temporary directory created by metaconfig and friends.
• .newer — A list of files newer than patchlevel.h, used by the patching tools.
• .package — Main configuration file used by most of the dist tools to make them smart.

• Index — A list of all the rules known by jmake. This file is located in the dist library directory.
• Jmakefile — Generic makefile description used by jmake.
• MANIFEST — List of all the files to be included in the distribution. Usually a copy (not a link) of MANIFEST.new.
• MANIFEST.new — List of all the files to be taken into account by the dist tools.
• Makefile.SH — The generated configured makefile (via Jmakefile) or hand-generated Makefile making use of known metaconfig symbols.
• Obsolete — A list of obsolete symbol used and their new equivalents.
• RCS — Directory where RCS files are stored.
• README — Main file explaining how to build your package.
• U — Private unit directory.
• Wanted — File used by metaconfig, listing all the symbols used by the sources.
• bugs — Directory where patches are stored.
• check.extra — Extra files present in MANIFEST.new, generated by manicheck.
• check.want — Missing files from MANIFEST.new, generated by manicheck.
• config_h.SH — Generated config.h template.
• confmagic.h — Magic symbol remapping, activated via metaconfig's -M option.
• hints — This directory lists all the configuration hints for your package.
• patchlevel.h — File recording your package patch level, should not be part of MANIFEST.new, but may be listed in MANIFEST, at your discretion.
• users — File recording the users of your package, generated by mailagent's package command (see the MailAuthor.U unit and mailagent 3.0).

🌸 ENVIRONMENT 🌸

The following environment variable is paid attention to:

• DIST — Location of the dist profile, defaults to ~/.dist_profile. This variable is subject to ~name substitution, even if your shell does not support it. 😭 (yes, even then. it's just built different.)
