DBCOLNEATEN(1)

okay bestie, welcome to the DBCOLNEATEN(1) page — a User Contributed Perl Documentation moment for dbcolneaten. Buckle up, because we're making Fsdb columns look neat under a monospaced font, and it's gonna slay. 💅✨

🌸 NAME 🌸

dbcolneaten — pretty-print columns of Fsdb data (assuming a monospaced font).

🦋 SYNOPSIS 🦋

dbcolneaten [-E] [field_settings]

✨ DESCRIPTION ✨

So dbcolneaten arranges things so your Fsdb data appears in neat columns if you view it with a monospaced font. The way it does this? It pads out each field with spaces to line up the next field. Iconic. 🎀

Field settings are of the form:

field op value

OP is >=, =, or <=, specifying that the width of that FIELD must be more, equal, or less than that VALUE. Yes, that's a width vibe check. 💅

dbcolneaten runs in O(1) memory but disk space proportional to the size of data. Lowkey efficient, highkey disk-hungry. 🫶

💖 OPTIONS 💖

• -E, --noeoln — Omit padding for the last column (at the end-of-the-line). This is the default behavior. 💅
• -e, --eoln — Do padding and include an extra field separator after the last column. Useful if you're interactively adding a column. ✨

This module also supports the standard fsdb options:

• -d — Enable debugging output.
• -i, --input InputSource — Read from InputSource, typically a file name, or - for standard input, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
• -o, --output OutputDestination — Write to OutputDestination, typically a file name, or - for standard output, or (if in Perl) a IO::Handle, Fsdb::IO or Fsdb::BoundedQueue objects.
• --autorun, --noautorun — By default, programs process automatically, but Fsdb::Filter objects in Perl do not run until you invoke the run() method. The --(no)autorun option controls that behavior within Perl.
• --help — Show help.
• --man — Show full manual.

Real talk: it does not handle tab separators correctly. That's the bug, bestie. Don't come for me, come for the tabs. 😭
