| This overlay provides a 'liquid' mode to the excellent CodeMirror editor (http://codemirror.net/). | |
| Add something like this to your CSS: | |
| .cm-liquid-tag { | |
| color: #32273f; | |
| background: #ead9ff; | |
| } | |
| .cm-liquid-variable { | |
| color: #29739b | |
| background: #c2e0f0; | |
| } | |
| */ | |
| CodeMirror.defineMode("liquid", function(config, parserConfig) { | |
| var liquidOverlay = { | |
| token: function(stream, state) { | |
| // Variables. | |
| if (stream.match("{{")) { | |
| while ((ch = stream.next()) != null) | |
| if (ch == "}" && stream.next() == "}") break; | |
| return "liquid-variable"; | |
| } | |
| // Tags. | |
| if(stream.match("{%")) { | |
| while ((ch = stream.next()) != null) | |
| if (ch == "%" && stream.next() == "}") break; | |
| return "liquid-tag"; | |
| } | |
| while (stream.next() != null && !stream.match("{{", false) && !stream.match("{%", false)) {} | |
| return null; | |
| } | |
| }; | |
| return CodeMirror.overlayParser(CodeMirror.getMode(config, parserConfig.backdrop || "text/html"), liquidOverlay); | |
| }); |
Appreciate this thanks
Nice
whats overlayParser? where it comes from?
There's a more complete liquid mode for CodeMirror here: https://github.com/axtro/codemirror_liquid_mode. It supports variables, arguments, operators, etc. It's written for pre-ES6 JavaScript, but it still works for us today.
To make this gist or the mode I linked work for newer CodeMirror (I think 3+), you have to replace CodeMirror.overlayParser with CodeMirror.overlayMode.
