addtoluatexpath

The addtoluatexpath package provides a convenient way to add input and Lua package paths in your document. You may want this package, for example, if a .cls or .sty file is located on a network or cloud storage drive.

Usage

• You can either pass the comma-separated paths via package options like \RequirePackage[path1,path2]{addtoluatexpath} in pre-amble, or by using the macro \addtoluatexpath{path1,path2} after the package has been loaded.
• If you wish to include first-level sub-directories as well as a path, inlcude a /* at the end of the path. eg. \RequirePackage[C:/Users/me/Desktop/*]{addtoluatexpath} adds your Desktop and all folders in the desktop to path.
• If you wish to include all nested sub-directories of all levels, include a /** at the end of the path.
• If you want to add to Lua path (package.path) only, include notex=true in the argument.
• If you want to add to tex input path only, include nolua=true in the argument. eg. \RequirePackage[nolua=true, C:/Users/me/Desktop/*, /**]{addtoluatexpath}
• The lua functions below are globally defined:
• atlp_main(paths_str) is the main function that runs
• atlp_paths = {} is a table containing all paths added by this package
• atlp_find_file(file_str) is a function that returns the full path of a file, it searches through all paths that were input to this package and returns the first valid. If no paths are found, an error is issed

Note

This package appends to the package.path Lua variable and the \input@path command (it first uses \providecommand to intialize it). Lua files in the added paths can then added via require'fileinpath1'; however loadfile and dofile still require the full path. graphicx internally uses \input@path as a default list of the paths; therefore, paths specified by this package will also include graphics if the graphicx package is loaded after paths are set. However, if \graphicspath{} is used after paths are added by this package, graphics search paths will not use \input@path, omitting the paths you added with this package.

Dependencies

luacode, luakeys, penlight (only if using * in paths)
