[Monotone-devel] Monotone Lua Hook for debian/changelog

[Richard Laager]

The following hook, which I'm posting in case it's useful to anyone
else, grabs the top entry from debian/changelog to use as a commit
message.

default_edit_comment = edit_comment
function edit_comment(basetext, user_log_message)
        local debian_changelog = io.open("debian/changelog")
        if (debian_changelog ~= nil) then
                if (not string.find(basetext, "patched  debian/changelog")) then
                        io.stderr:write("mtn: misuse: debian/changelog exists, 
but was not modified\n")
                        return nil
                end

                local res = ""
                local line = debian_changelog:read()
                while(line ~= nil) do
                        res = res .. line .. "\n"
                        if (string.find(line, "^ --")) then
                                return res
                        end
                        line = debian_changelog:read()
                end

                io.stderr:write("mtn: misuse: error parsing debian/changelog\n")
                return nil
        end
        return default_edit_comment(basetext, user_log_message)
end
