# luarocks config Query information about the LuaRocks configuration. # Usage ``` luarocks config ( | --scope= | --unset --scope= | ) ``` When given a configuration key, it prints the value of that key according to the currently active configuration (taking into account all config files and any command-line flags passed) Examples: * `luarocks config lua_interpreter` * `luarocks config variables.LUA_INCDIR` * `luarocks config lua_version` When given a configuration key and a value, it overwrites the config file (see the --scope option below to determine which) and replaces the value of the given key with the given value. * `lua_dir` is a special key as it checks for a valid Lua installation (equivalent to --lua-dir) and sets several keys at once. * `lua_version` is a special key as it changes the default Lua version used by LuaRocks commands (equivalent to passing --lua-version). Examples: * `luarocks config variables.OPENSSL_DIR /usr/local/openssl` * `luarocks config lua_dir /usr/local` * `luarocks config lua_version 5.3` When given a configuration key and --unset, it overwrites the config file (see the --scope option below to determine which) and deletes that key from the file. Example: `luarocks config variables.OPENSSL_DIR --unset` When given no arguments, it prints the entire currently active configuration, resulting from reading the config files from all scopes. Example: `luarocks config` ## Options ``` --scope= The scope indicates which config file should be rewritten. Accepted values are "system", "user" or "project". * Using a wrapper created with `luarocks init`, the default is "project". * Using --local (or when `local_by_default` is `true`), the default is "user". * Otherwise, the default is "system". --json Output as JSON ```
