finding locations of many files via kpse

[Erik Nijenhuis]

I was a little bit confusing for option two I guess. Here's the MWE:

Execute with: texlua kpse_search.lua

For example:
texlua kpse_search.lua logo.png gitinfo-lua.lua lua-placeholders.sty

Prints:
Found: logo.png -> /home/erik/texmf/tex/generic/images/logo.png
Found: gitinfo-lua.lua -> /home/erik/src/latex/gitinfo-lua/scripts/gitinfo-
lua.lua
Found: lua-placeholders.sty -> /home/erik/src/latex/lua-placeholders/tex/lua-
placeholders.sty

Contents kpse_search.lua:
-- kpse_search.lua

local kpse = kpse or require 'kpse'

kpse.set_program_name('lualatex')

local function print_usage()
    print("Usage: kpse_search.lua <path1> <path2> ... <pathN>")
end

local paths = arg

if #paths == 0 then
    print("No paths provided.")
    print_usage()
    os.exit(1)
end

for _, path in ipairs(paths) do
    local result = kpse.find_file(path)
    if result then
        print(string.format("Found: %s -> %s", path, result))
    else
        print(string.format("Not found: %s", path))
    end
end
-- end of file

Sorry for the earlier clutter :|
