Press `Ctrl+E` (`⌘E` -on Mac OSX | `M-C` in curses) to display the entry. It is useful for debugging, -inspecting, and entering `buffer` or `view` commands. If you try to cause -instability in Textadept's Lua state, you will probably succeed so be careful. -The [Lua API][] lists available commands. The command entry provides abbreviated -commands for [`buffer`][], [`view`][] and [`ui`][]: you may reduce the -`buffer:append_text('foo')` command to `append_text('foo')`. Therefore, use -`_G.print()` for Lua's `print()` since `print()` expands to [`ui.print()`][]. -These commands are runnable on startup using the `-e` and `--execute` command -line switches. - - - -[Lua API]: api/index.html -[`buffer`]: api/buffer.html -[`view`]: api/view.html -[`ui`]: api/ui.html -[`ui.print()`]: api/ui.html#print - -### Tab Completion - -The command entry also provides tab-completion for functions, variables, tables, -etc. Press the `Tab` (`⇥` on Mac OSX | `Tab` in curses) key to display a list of -available completions. Use the arrow keys to make a selection and press `Enter` -(`↩` | `Enter`) to insert it. - - - -### Extending - -Executing Lua commands is just one of the many tools the command entry functions -as. For example, *modules/textadept/find.lua* and *modules/textadept/keys.lua* -extend it to implement [incremental search][]. - -[incremental search]: api/ui.find.html#find_incremental - -## Command Selection - -If you did not disable the menu in your [preferences][], then pressing -`Ctrl+Shift+E` (`⌘⇧E` on Mac OSX | `M-S-C` in curses) brings up the command -selection dialog. Typing part of any command filters the list, with spaces being -wildcards. This is an easy way to run commands without navigating the menus, -using the mouse, or remembering key bindings. It is also useful for looking up -particular key bindings quickly. Note: the key bindings in the dialog do not -look like those in the menu. Textadept uses this different notation internally. -Learn more about it in the [keys LuaDoc][]. - -[preferences]: 08_Preferences.html#User.Init -[keys LuaDoc]: api/keys.html - -## Shell Commands and Filtering Text - -Sometimes using an existing shell command to manipulate text is easier than -using the command entry. An example would be sorting all text in a buffer (or a -selection). One way to do this from the command entry is: - - ls={}; for l in buffer:get_text():gmatch('[^\n]+') do ls[#ls+1]=l end; - table.sort(ls); buffer:set_text(table.concat(ls, '\n')) - -A simpler way is pressing `Ctrl+|` (`⌘|` on Mac OSX | `^\` in curses), entering -the shell command `sort`, and pressing `Enter` (`↩` | `Enter`). - -This feature determines the standard input (stdin) for shell commands as -follows: - -* If text is selected and spans multiple lines, all text on the lines containing - the selection is used. However, if the end of the selection is at the - beginning of a line, only the EOL (end of line) characters from the previous - line are included as input. The rest of the line is excluded. -* If text is selected and spans a single line, only the selected text is used. -* If no text is selected, the entire buffer is used. - -The standard output (stdout) of the command replaces the input text. - -## Remote Control - -Since Textadept executes arbitrary Lua code passed via the `-e` and `--execute` -command line switches, a side-effect of [single instance][] functionality on the -platforms that support it is that you can remotely control the original -instance. For example: - - ta ~/.textadept/init.lua & - ta -e "events.emit(events.FIND, 'require')" - -[single instance]: 02_Installation.html#Single.Instance |
