The ending (back)slash is preserved if present. I'd stick with / ⦠But as you pointed out, Lua is portable tonon-Unix systems that do not have path concepts, but it DOES use pathsin systems that support it. Declare a module. You might want to create a library because you have some functions which are used in multiple programs, or just to split your program into multiple more modular files. PWD (capital letters) PWD configures the absolute path as the origin path of the relative path ⦠Note the dot .. A common pattern for modules is to have abc.lua and abc/xyz.lua; to require files in a subdirectory like that, use the following: require "abc" require "abc.xyz" So in summary, require() with relative paths is not working for lualatex, but works for texlua commands. For example, if you use an embedded engine, you may want to check if the path reported by the engine is normalized (doesnât include ../ references) by checking the result of debug.getinfo(1,"S").source . Information here may be outdated. In Lua, the require() function caches modules. However, I'd rather use an absolute path based only on my site's top-level directory, and not on whichever file I'm currently in. I've also tried `require "tiles"` with tiles.lua in the same directory as main.lua but that doesn't work either) EDIT: Turns out require does not want the path relative to your current path, but from the root datafiles path⦠See [Dynamic-Link Library Search Order] for the rules governing the order of search smartding return relative path from file_relative ⦠4a1528c Dec 10, 2020. return relative path from file_relative . I've been asking myself if Lua actually has a path separator. params = base_parsed. Adjustment happens whenever 'runtimepath' is changed. (It should be noted that tiles.lua is located in src/tiles.lua in relation to main.lua. as a placeholder for a library name passed to require.An example would make this much easier to explain I'm using the following code in test/ball_test.lua to require ball.lua from the parent directory: package.path = package.path .. ";../entity.lua" require("entity") package.path = package.path .. ";../ball.lua" require("ball") entity.lua is a dependency of ball.lua. The argument passed to require will be inserted in place of any question mark ("?") is. the path where lua scripts live, relative to the MQ2 root directory default: 'lua' luaRequirePaths list of additional require lookup paths, written in lua require lookup format appends the global package.path in lua environments default: empty list dllRequirePaths No need to explicitly define what to export. It uses the values of LUA_PATH and LUA_CPATH at the time of configuration for the installation of Lmod. params: if not relative_parsed. Some of the features of the library include: Support for HTTP versions 1, 1.1 and 2 as specified by RFC 7230 and RFC 7540. For more flexibility, see LuaMapHandler . This path must reflect the position of the current file within your site's directory structure. The usage for requiring the files in a folder is: Code: Select all. lua-http is an performant, capable HTTP and WebSocket library for Lua 5.1, 5.2, 5.3 and LuaJIT. It is a semi-colon delimited list of paths, using '?' The conventions are similar to VimL plugins, with some extra features. lua_concat(L, 2); } and call that function from within *findfile: static const char *findfile (lua_State *L, const char *name, const char *pname, const char *dirsep) { const char *path; lua_getfield(L, lua_upvalueindex(1), pname); appendcurrentpath(L, pname); // insert the call here path = lua_tostring(L, -1); if (path == NULL) luaL_error(L, "'package.%s' must be a string", pname); return searchpath(L, name, path, ⦠To lua, every file loaded via loadfile or require is identified by a path - a string. A library is a collection of useful functions and other definitions which is stored separately to your main program. The other main job of require is to avoid loading the same file twice. relative lua ⦠These two are the ones using the path variables to find what they are looking for. For that purpose, it keeps a table with the names of all loaded files. However, ANSI C (the abstract platform where Lua runs) does not have the concept of directories. Therefore, the path used by require is a list of patterns , each of them specifying an alternative way to transform a virtual file name (the argument to require ) into a real file name. If you are requiring a file inside lib.foo.bar, you might be doing something like this: Then you can get the path to the file as the first element (and only) ... variable, when you are outside all functions. In other words: Now, to get the "folder" you need to remove the filename. Failed to load latest commit information. Provides both client and server APIs. query: end: end: else: relative_parsed. package.loaded A table used by require to control which modules are already loaded. Let's say we want to create a small library to make working with the terminal a little easier. Not really. GAME - IGameInfoCallback API; BATTLE - IBattleInfoCallback API end } ----- Thanks, it is quite useful. Rather they should place their custom libraries in /usr/lib/ Defines a list of library search paths that require iterates to find libraries. To determine its path, require first checks the global variable LUA_PATH. require_here (base) prefixes the current script's path to the Lua module path. However, I cannot get lualatex to find them there. See |lua-require-example| for a walkthrough. The paths are relative to the game's source and save directories, as well as any paths mounted with love.filesystem.mount. Using relative modules paths provide better locality and are more robust in case of parent group renaming. Call a module. params then: relative_parsed. local filename = "subdirec/file.xml". I know this is a related question, but it is 2011 and the solution is inelegant as I would have to manually change the require call for each external module. mod_lua provides a handler named lua-script , which can be used with a SetHandler or AddHandler directive: SetHandler lua-script . Lua is simple, except for importing module using relative path. This will cause mod_lua to handle requests for files ending in .lua by invoking that file's handle function. We'll provide two functions: reset, which clears the terminal and sets the cursor to (1, 1), and Validate a filename or apply a replacement function on it in order to make it valid. Remember, Lua uses the standard C library [2] and the C standard> library makes no mention of paths (or directories for that matter). local _M = {} function _M. This require a workaround with package.path. Applies to both the source and the binary module paths. And thatâs it. Module is like a library that can be loaded using requireand has a single global name containing a First, require searches for the file in a path; second, require controls whether a file has already been run to avoid duplicating the work. Because of these features, require is the preferred function in Lua for loading libraries. The path used by require is a little different from typical paths. The argument passed to require will be inserted in place of any question mark ("?") I should make a summary: require a .lua file not use ".lua" because require treat '.' Therefore, the LUA_CPATH is not used. Returns nil if the paths are of different types or donât have a base path in common. This new version uses the technique that Tim suggested. It does, as the Lua Unofficial FAQ tell us: package.config is a string where the first 'character' is the directory separator; so package.config:sub(1,1) is either a slash or a backslash. path or " ", relative_parsed. ;?.lua", although it is easy to change that when you compile Lua). It should work both for files loaded with require, and for files called via the command line. Then use requireRel instead of require for those you wish to be loaded with a relative path. Not the answer you're looking for? Browse other questions tagged lua require corona or ask your own question. query then: relative_parsed. The path of the file known to the IDE may not be the same as the path known to the Lua engine. When a module is requested as in Then Lua will start looking for the module named It extends require with some methods. package.path = package.path .. ";C:\\Users\\Me\\MyLuaProject" require "foo" You can also add it to the LUA_PATH environment variable, but this is probably less easy to modify on the fly. As a general rule, try to use this when building paths. All it does is apply some textual transformations to a filename before ultimately calling fopen() (the C call). package.path It is recommended that users do not change the default package.path. character in each template (after the dot characters in the argument passed to require are replaced by directory separators.) Lua uses the `require` function to load external libraries, to find the modules Lua uses package searchers. To Lua, the filesystem is âa black box that transforms paths into sourceâ. Convert an absolute path into a relative path which is relative to pwd. I've been attempting to use dofile, require, and filepath strings to call the libraries along with additional files like so: dofile ("subdirec/script.lua") require "subdirec.script". Note: A C module cannot be loaded for require( ) in this function. This string is passed to the operative system, which will load the file into a string and return it to Lua. They can't change the value of LUA_PATH after Lmod is installed to find it. E.g: luapackage.path = package.path .. '../folder1/your_file If you use love2d, you can use lua love.filesystem.setRequirePath(your_path) Because love2d only execute the main.lua file, you can simply put your main.lua file at the root folder. path = absolute_path (base_parsed. But as you pointed out, Lua is portable to > non-Unix systems that do not have path concepts, but it DOES use paths > in systems that support it. If a required ⦠DATA - persistent table DATA.ERM contains ERM state, anything else is free to use. or a slash /. ... --require this lua file somewhere in your `init.vim`, or use `:lua` require (' el '). "Lua ⦠The use of those is beyond the scope of this post, but the one thing you need to know is that the searcher for Lua modules is tried first and if it fails, the searcher for C modules will be used. relative_parsed. Git stats. Relative path in config file is relative to the nginx.conf, but lua_package_path cannot. Path separators are denoted by either a dot . Finally, if both checks fail, require uses a fixed path (typically "? Globals. Lua API Reference [Todo] In near future Lua API may change drastically several times. query = base_parsed. So I require("entity") first otherwise I get a module 'entity.lua' not found error. If the value of LUA_PATH is a string, that string is the path. This means that sites will have to use LMOD_PACKAGE_PATH to let Lmod know where SitePackage.lua. The proper way to do relative requires is: thismod/init.lua ----- local modname = ... local submod = require(modname .. ".submod") return {submod=submod} ----- thismod/submod.lua ----- return { helloworld = function() print("Hello World!") luvit / deps / require.lua Go to file Go to file T; Go to line L; ... description = "Luvit's custom require system with relative requires and sane search paths." 4a1528c. Normally, when referencing a file with require() a relative path is used. Sure, you are correct. path: if not relative_parsed. as '\\' when require "a.lua" the lua will look for "a\lua.lua" so when use relative path "..\" like require "..\\a\\a" you will never get right path the lua will look for \\a\a.lua still in the same dir b is that a bug ? The module path can be absolute or relative to the caller module's group in the project source file tree. Otherwise, require checks the environment variable LUA_PATH. character in each template (after the dot characters in the argument passed to require are replaced by directory separators.) The paths are relative to the game's source and save directories, as well as any paths mounted with love.filesystem.mount. 47 commits Files Permalink. 1. It makes it easy for the main file of a multi-file program to access its modules in the same directory. hc (arguments) os.execute ("herbstclient ".. arguments) end return _M. ===== IMPORTING LUA MODULES * lua-require* * lua-package-path* Nvim automatically adjusts `package.path` and `package.cpath` according to effective 'runtimepath' value. I want to move all .lua files into the subdirectory code to avoid polluting the main directory with them. path = base_parsed. For example, 'Layouts.SquareGrid' is a valid module path specifying a Lua module named 'SquareGrid' in a group name 'Layouts'. path.filename(s, [pl], [repl]) -> s|nil,err,errcode. However, when I attempt using this syntax and open Wireshark I get the âfile does not exist errorâ. Lua initializes the C path package.cpath in the same way it initializes the Lua path package.path, using the environment variable LUA_CPATH or a default path defined in luaconf.h. If LUA_PATH is not configured, "./?.lua;" will be used as the default path.
