i started this off by trying to learn more about how scheme does file
i/o. it seems like many of its functions just expect you'll want them to
write to (current-output-port) instead of returning a string. so i
thought, i wonder what it would look like if i tweak these content
generator functions to just (display) their stuff, and
call (with-output-to-file) and apply the html template each time i call
them?
and whew it kindof got away from me
i totally understand if you feel like this is an unpleasant overhaul of
your whole project and don't want to merge this change!
anyway let's see if i can summarize the changes:
- image support!!
- svg image support!! it shows both the svg and its source code!
- markdown support; we now render all .md files instead of showing source
- using string->goodHTML instead of clean-html. turns out, it's a little
annoying, in that it only returns a string if it makes no changes, but
if it does, it returns a list of strings. it expects to be passed to
one of the other functions in the sxml library, so that's what i do.
- moved "wrap the template" outside of various "generate content"
functions
- simple command line use: from any git work-tree OR bare repo, run
repo2html /path/to/www/output/repo-foo-bar and it will create that
directory and use "repo-foo-bar" as the repo name.
- made our example post-receive a bit more robust
- changed env var names to have REPO2HTML_ prefix
- better repo name detection and automatic caching of it in git config
- moved the post-receive-specific logic to avoid generating if we're
not updating HEAD into the post-receive hook itself, along with some
status messages
- checked directory permissions in the hook so it doesn't even attempt
to run repo2html and avoids a crash
