I am making an editor for LPMLN language which currently has no highlighting support in ACE editor. I tried to embed the script as guide in my index.html site but I can't add it locally with local relative path. So I can only try the CDN way by adding the URL of the script, which works. However, then I defined the highlighting rules in highlighting javascript files. So the URL way won't work since the existing library has no such files. Then I tried to post the code on github and copy the CDN link to load my script, but it can't seem to work. I have tested my highlighting file in mode creator link: https://ace.c9.io/tool/mode_creator.html and it gives the right highlighting display.
This is my html code(from body):
<body>
<div id="editor">%example:
1:go_out(today,a):-not rain(today),free(a,today).
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/ace/1.4.2/ace.js" type="text/javascript"></script>
<script src="https://raw.githack.com/BobHuNanjing/myeditor/master/ace/mode/mode-lpmln" type="text/javascript" charset="utf-8"></script>
<script>
var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.session.setMode("ace/mode/lpmln");
</script>
<app-root></app-root>
</body>
</html>
And here is my highlighting js file:
define('ace/mode/lpmln',function(require, exports, module) {
"use strict";
var oop = require("../lib/oop");
var TextHighlightRules = require("./text_highlight_rules").TextHighlightRules;
/* --------------------- START ----------------------------- */
var LpmlnHighlightRules = function() {
this.$rules = {
"start" : [
{
"token" : "keyword.other.define",
"regex" : "(\\:-)"
},
{
"token" : "keyword.operator.naf",
"regex" : "((not))"
},
{
"token" : "keyword.operator.neg",
"regex" : "([\\-])"
},
{
"token" : "markup.underline.weight",
"regex" : "(\\d+:)"
},
{
"token" : "string.regexp",
"regex" : "(^\\w+(\\.*\\d{0,2})([+*/-]\\w+(\\.*\\d{0,2}))+)"
},
{
"token" : "comment.line.percentage",
"regex" : "(\\%.*)"
},
{
"token" : "support.varaiable",
"regex" : "([\\(\\)])"
},
{
"token" : "variable.parameter",
"regex" : "(?<=\\().*?(?=\\,)|(?<=\\,).*?(?=\\))"
},
{
defaultToken : "text",
}
]
};
this.normalizeRules();
};
/* ------------------------ END ------------------------------ */
oop.inherits(LpmlnHighlightRules, TextHighlightRules);
exports.LpmlnHighlightRules = LpmlnHighlightRules;
});
As I can see, the theme is correctly loaded, which must be existing under the path of the cloudflare CDN. But my script was not loaded. I have also tried ace.config.setModuleUrl('ace/mode/lpmln',"https://raw.githack.com/BobHuNanjing/myeditor/master/ace/mode/mode-lpmln.js")
, the console shows no error but nothing highlighting displays.
So how should I correctly import the ace.js and how to correctly add a new highlighting js file and make it work?
To define syntax for Ace you need both highlight rules and a mode that controls folding autoindent, etc., see https://github.com/ajaxorg/ace-builds/blob/0d62c26de7b2e1922d8dd95ba587c9845c018c51/src/mode-json.js#L257 and https://ace.c9.io/#nav=higlighter
Here is a snippet that modifies your example to work by adding mode definition
define('ace/mode/lpmln',function(require, exports, module) {
"use strict";
var oop = require("../lib/oop");
var TextHighlightRules = require("./text_highlight_rules").TextHighlightRules;
// to define highlighting we need mode and highlight rules
// normally highlight rules are defined in a separate file,
// but since this is used only in one place, this function is directly in the mode
var LpmlnHighlightRules = function() {
this.$rules = {
"start" : [
{
"token" : "keyword.other.define",
"regex" : "(\\:-)"
},
{
"token" : "keyword.operator.naf",
"regex" : "((not))"
},
{
"token" : "keyword.operator.neg",
"regex" : "([\\-])"
},
{
"token" : "markup.underline.weight",
"regex" : "(\\d+:)"
},
{
"token" : "string.regexp",
"regex" : "(^\\w+(\\.*\\d{0,2})([+*/-]\\w+(\\.*\\d{0,2}))+)"
},
{
"token" : "comment.line.percentage",
"regex" : "(\\%.*)"
},
{
"token" : "support.varaiable",
"regex" : "([\\(\\)])"
},
{
"token" : "variable.parameter",
"regex" : "(?<=\\().*?(?=\\,)|(?<=\\,).*?(?=\\))"
},
{
defaultToken : "text",
}
]
};
this.normalizeRules();
};
/* ------------------------ END ------------------------------ */
oop.inherits(LpmlnHighlightRules, TextHighlightRules);
exports.LpmlnHighlightRules = LpmlnHighlightRules;
var oop = require("../lib/oop");
var TextMode = require("./text").Mode;
var CstyleBehaviour = require("./behaviour/cstyle").CstyleBehaviour;
var CStyleFoldMode = require("./folding/cstyle").FoldMode;
var Mode = function() {
this.HighlightRules = LpmlnHighlightRules;
this.$behaviour = new CstyleBehaviour();
this.foldingRules = new CStyleFoldMode();
};
oop.inherits(Mode, TextMode);
(function() {
this.$id = "ace/mode/lpmln";
}).call(Mode.prototype);
exports.Mode = Mode
});
// after the mode is defined initialize the editor
// this can be in another file, but this playground doesn't allow to create multiple files
var editor = ace.edit("editor");
editor.setTheme("ace/theme/monokai");
editor.session.setMode("ace/mode/lpmln");
