Dear all,
I'm currently updating luatexbase, and I have a few questions:
The first two are related to the behaviour when searching for
"module.submodule" as "module/submodule.lua":
- Am I right if I say that package.searchers[2] looks weel for it but
kpse.find_file("module.submodule", 'lua') doesn't?
Yes. But package.searchers[2] is quite trivial. In lua code, it would
look like this:
function search (name)
altname = string.gsub(file,'.','/')
filename = kpse.find_file(altname, 'lua')
if not filename then
filename = kpse.find_file(name, 'lua')
end
if not filename then
return string.format("[kpse lua searcher] file not found: %s", name)
else
return loadfile(filename)
end
end
- If it's true, is there a way to make it work with kpse.find_file?
Just write a thin wrapper to replace '.' with '/', as above.
The goal of not just letting packages.searchers[2] do his job quietly
(which it does well), is just to print the name of the loaded file,
between brackets... So the third question is:
- is it possible to make the kpse version of packages.searchers[2]
return a string containing the file name?
That is not possible. It has to return either an error string, or a
loader function (the result of loadfile()).
Best wishes,
Taco
