I'm new to ace-editor and I have included custom mode to validate my code and every line should end up with semicolon, If semicolon is not present in my query by mistake then the editor should gives up the warning like "Missing Semicolon".
define('ace/mode/javascript-custom', [], function(require, exports, module) {
var oop = require("ace/lib/oop");
var TextMode = require("ace/mode/text").Mode;
var Tokenizer = require("ace/tokenizer").Tokenizer;
var ExampleHighlightRules = require("ace/mode/example_highlight_rules").ExampleHighlightRules;
var Mode = function() {
this.HighlightRules = ExampleHighlightRules;
};
oop.inherits(Mode, TextMode);
(function() {
this.lineCommentStart = "--";
this.blockComment = {
start: "->",
end: "<-"
};
}).call(Mode.prototype);
exports.Mode = Mode;
});
define('ace/mode/example_highlight_rules', [], function(require, exports, module) {
var oop = require("ace/lib/oop");
var TextHighlightRules = require("ace/mode/text_highlight_rules").TextHighlightRules;
var ExampleHighlightRules = function() {
var keywordMapper = this.createKeywordMapper({
"variable.language": "this",
"keyword": "one|two",
"constant.language": "true|false|null"
}, "text", true);
this.$rules = {
"start": [{
token: "comment",
regex: "->",
next: [{
regex: "<-",
token: "comment",
next: "start"
}, {
defaultToken: "comment"
}]
}, {
regex: "\\w+\\b",
token: keywordMapper

token: "comment",

}, {
token: "string",
regex: '"',
next: [{

}, {

}]
}, {
token: "numbers",
regex: /\d+(?:[.](\d)*)?|[.]\d+/
}]
};
this.normalizeRules()
};
oop.inherits(ExampleHighlightRules, TextHighlightRules);
exports.ExampleHighlightRules = ExampleHighlightRules;
});
var langTools = ace.require("ace/ext/language_tools");
var editor = ace.edit("editor");
editor.session.setMode("ace/mode/javascript-custom");
editor.setOptions({
enableBasicAutocompletion: true,
enableLiveAutocompletion: true
});
editor.setTheme("ace/theme/monokai");
var lines = editor.session.doc.getAllLines();
var errors = [];
for (var i = 0; i < lines.length; i++) {
if (/[\w\d{(['"]/.test(lines[i])) {
alert("hello");
errors.push({
row: i,
column: lines[i].length,
text: "Missing Semicolon",
type: "error"
});
}
}

UPDATE:
The following js files are generated from ace and added to my rails application, the files are loaded in rails app but the functionality (semicolon check) doesn't seem to be working.
worker-semicolonlineend - http://pastebin.com/2kZ2fYr9 mode-semicolonlineend - http://pastebin.com/eBY5VvNK
Update:
- In ace editor, type in a query1, query2 in line 1 and line 2 respectively
- Leave the third line blank
- Now in fourth line, type a query without semicolon in the end, x mark appears in third line 5 And when the fifth line is also without a semicolon, then the x mark is displayed at fourth query
Ace editor widely support this kind analysis for JavaScript by default:
Just make sure that worker file
worker-javascript.js
is available for your code. In code snippet above I use CDN to get Ace build, so worker is always available. You can configure JSHint via worker options.Update: But if really need something beyond that you will need to do the following as my understanding goes:
Worker
andMode
for you kind of analysiseditor.getSession().setMode("ace/mode/semicolonlineend");
Worker that perform line ending check will look something like that:
New mode that uses worker:
