3 -- This commit filter maps a subject line to a search URL of a public-inbox
4 -- disclaimer: written by someone who does not know Lua.
6 -- This requires cgit linked with Lua
7 -- Usage (in your cgitrc(5) config file):
9 -- commit-filter=lua:/path/to/this/script.lua
11 -- Example site: https://80x24.org/public-inbox.git/
14 urls['public-inbox.git'] = 'https://public-inbox.org/meta/'
15 -- additional URLs here...
16 -- TODO we should be able to auto-generate this based on "coderepo"
17 -- directives in the public-inbox config file; but keep in mind
18 -- the mapping is M:N between inboxes and coderepos

26 -- cgit opens and closes this filter for the commit subject
27 -- and body separately, and we only generate the link based
28 -- on the commit subject:

30 u = urls[os.getenv('CGIT_REPO_URL')]
34 html('<a href="' .. u .. '?x=t&q=')
35 html_url_arg('"' .. buffer .. '"')
41 -- pass the body-through as-is
42 -- TODO: optionally use WwwHighlight for linkification like
43 -- cgit-wwwhighlight-filter.lua
