gtk-look finds and displays HTML documentation for GTK, GNOME and Glib functions and variables in Emacs, similar to what info-lookup-symbol does for info files (C-h S). The documentation is expected to be devhelp indexes with HTML files. The location of the indexes can be customized. In addition to C code development gtk-look is good for

• perl-gtk2, recognising class funcs like Gtk2::Label->new and bare method names like set_text.

• guile-gnome, recognising methods like set-text and classes like <gtk-window>.

lua-mode provides support for editing Lua, including automatic indentation, syntactical font-locking, running interactive shell, Flymake checks with luacheck, interacting with `hs-minor-mode and online documentation lookup. The following variables are available for customization (see more via `M-x customize-group lua`): - Var `lua-indent-level': indentation offset in spaces - Var `lua-indent-string-contents': set to `t` if you like to have contents of multiline strings to be indented like comments - Var `lua-indent-nested-block-content-align': set to `nil to stop aligning the content of nested blocks with the open parenthesis - Var `lua-indent-close-paren-align': set to `t to align close parenthesis with the open parenthesis, rather than with the beginning of the line - Var `lua-mode-hook': list of functions to execute when lua-mode is initialized - Var `lua-documentation-url': base URL for documentation lookup - Var `lua-documentation-function': function used to show documentation (`eww` is a viable alternative for Emacs 25) These are variables/commands that operate on the Lua process: - Var `lua-default-application': command to start the Lua process (REPL) - Var `lua-default-command-switches': arguments to pass to the Lua process on startup (make sure `-i` is there if you expect working with Lua shell interactively) - Cmd `lua-start-process': start new REPL process, usually happens automatically - Cmd `lua-kill-process': kill current REPL process These are variables/commands for interaction with the Lua process: - Cmd `lua-show-process-buffer': switch to REPL buffer - Cmd `lua-hide-process-buffer': hide window showing REPL buffer - Var `lua-always-show': show REPL buffer after sending something - Cmd `lua-send-buffer': send whole buffer - Cmd `lua-send-current-line': send current line - Cmd `lua-send-defun': send current top-level function - Cmd `lua-send-region': send active region - Cmd `lua-restart-with-whole-file': restart REPL and send whole buffer To enable on-the-fly linting, make sure you have the luacheck program installed (available from luarocks) and activate `flymake-mode'. See "M-x apropos-command ^lua-" for a list of commands. See "M-x customize-group lua" for a list of customizable variables.
