Insert a domain specific line-break

#1

In some editors, when you hit ctrl+enter the editor inserts a language domain specific newline character, ie:

<br /> for editing .html/.blade.php
\n for when editing .js/.php/.c/.py/etc.
\r\n for when editing .c/.py/etc. on windows
'n when editing .ps (i can’t escape backtick on this forum markdown, somehow broken, it’s a backtick, not an apostrophe)
&#10; for .xml

maybe i’ve missed some

Can i configure this somehow in sublime? I can’t seem to find something like this in either key bindings or settings.

Most straight forward approach would be to define key bindings…

	{
		"keys": ["ctrl+enter"],
		"command": "insert", "args": { "characters": "\\n" },
	},
	{
		"keys": ["ctrl+enter"],
		"command": "insert", "args": { "characters": "'n" },
		"context": [
			{"key": "selector", "operand": "source.ps - source.ps source - source.ps text"}
		],
	},
	{
		"keys": ["ctrl+enter"],
		"command": "insert", "args": { "characters": "<br />" },
		"context": [
			{"key": "selector", "operand": "text.html - text.html source - text.html html"}
		],
	},
	{
		"keys": ["ctrl+enter"],
		"command": "insert", "args": { "characters": "&#10;" },
		"context": [
			{"key": "selector", "operand": "text.xml - text.xml source - text.xml html"}
		],
	},

I guess it gets a bit more complicated for embedded languages, because you’d want the highest scoring selector to win, not the last defined thus highest priority keybinding

You are right.

Selectors have been updated to fix embedded code scenarios.

thank you for the reply! it looks good. although, i am super confused about “selector” and “operand”

i guess “selector” means it only selects this shortcut if the stuff in operand matches.

then, what is text.html - text.html source - text.html html?

if i want to create, let’s say, custom selector for .php, i should write “operand” text.php - text.php source - text.php php?

A “selector” is an expression of scopes to be matched against a point or region in a syntax highlighted file, to return whether it is of given scope. see: https://www.sublimetext.com/docs/selectors.html

You can use ctrl+shift+p in an open file to see, which scopes it uses.

PHP files’ main scope is text.html.php, which is already covered. To address <?php...?> you can use source.php - source.php source - source.php text.

- source.php source - source.php text is required to not apply key bindings in embedded syntaxes whithin PHP source code. This may be relevant for Blade or Twig.
