This documentation file was extracted from
dddoc.sh using the following
./dddoc.sh -d . dddoc.sh && mv dddoc.sh.md README.md
This script is designed to extract inline documentation from shell scripts or libraries, or any other language using the sharp (#) as a comment mark. It follows the tradition of POD (Plain Old Documentation), but permits an easier-to-read syntax, allowing you to use the markup language that suits you (such as MarkDown, txt2tags, etc.).
The only pre-requisite is that the comment lines to be extracted start with two sharps (##), hence the name of this script ("dièse" stands for "sharp" in French). The two sharps must be followed by at least one space or an end of line for the line to be extracted; for instance, lines starting with three sharps won't be extracted. Both sharps starting the line, and exactly one space (if any) will be stripped.
Each output file bares the name of the corresponding input file, with a
user-defined suffix (
-s switch), that defaults to "md".
The input file hierarchy is respected, and this script is best used along
xargs, for instance:
cd /project/path find * -type f -print0 | xargs -0 dddoc /path/to/destdir
The destination directory could be a clone of a GitLab wiki (or Gitea, or GitHub...), which will allow you to easily publish a nice-looking set of docs.
