ERRHDR(1)

💖 ERRHDR 💖

okay bestie, so errhdr is a lil NCBI Tools User's Manual girly and her whole thing is turning a file of messages into a C header file. that's it, that's the job. she's a compiler-adjacent baddie and she ate. ✨

🌸 SYNOPSIS 🌸

errhdr [-2] [-s] msgfile [hdrfile]

🦋 DESCRIPTION 🦋

so here's the tea 🍓 — errhdr reads a file that describes error codes and the messages that go with them, and then it produces a C header file. and where does that header go? either straight to standard output, or into hdrfile if you gave it one. main character energy, honestly.

the input file has a simple text-based format. no cap, it's giving very readable. one file — errmsg/valid.msg in the source tree — starts like this:

MODULE valid
$$ SEQ_INST, 1
$^   ExtNotAllowed, 1
# This is a comment
A Bioseq "extension" is used for special classes of Bioseq. This class of
Bioseq should not have one but it does. This is probably a software error.

$^   ExtBadOrMissing, 2
This class of Bioseq requires an "extension" but it is missing or of the
wrong type. This is probably a software error.

and lowkey the best part: detailed descriptions are optional, and you don't need any "end" lines of any sort. not one. not ever. iconic behavior fr fr 💅

okay that's the whole page, bestie!! this one came from NCBI, dated 2001-10-05, and it's page ERRHDR(1) of the NCBI Tools User's Manual. go make some headers, you absolute legend 🫶🎀🌟
