javascript - Values and captions in Ace Editor autocomplete -

i using ace editor v.1.1.8 ext-language_tools. want achieve following behavior auto-complete:

user starts typing, presses ctrl+space , show him list of found captions, when selects 1 of them value inserted.

my code:

var completions = [     {id: 'id1', 'value': 'value1'},      {id: 'id2', 'value': 'value2'} ]; var autocompleter = {     getcompletions: function(editor, session, pos, prefix, callback) {         if (prefix.length === 0) {             callback(null, []);             return;         }                             callback(             null,             completions.map(function(c) {                     return {value: c.id, caption: c.value};                 })         );     } }; editor.setoptions({     enablebasicautocompletion: [autocompleter],     enableliveautocompletion: false,     enablesnippets: false }); 

so need above user enters 'val', sees list 'value1' , 'value2', selects 1 of them , 'id1' or 'id2' inserted editor.

at point:

• editor searches value (and need search caption)
• if set 'value' = c.value, editor search correctly insert c.value while need c.id inserted.

upd:

was able achieve behavior adding insertmatch method data:

completions.map(function(c) {     return {         value: c.name,                     meta: c.id,         completer: {             insertmatch: function(editor, data) {                 if (editor.completer.completions.filtertext) {                     var ranges = editor.selection.getallranges();                     (var = 0, range; range = ranges[i]; i++) {                         range.start.column -= editor.completer.completions.filtertext.length;                         editor.session.remove(range);                     }                 }                 editor.execcommand("insertstring", data.meta);             }         }     }; }) 

you can change

var caption = item.value || item.caption || item.snippet; 

line @ https://github.com/ajaxorg/ace/blob/v1.1.8/lib/ace/autocomplete.js#l449

var caption = item.caption || item.value || item.snippet; 

you can implement custom insertmatch method on completer https://github.com/ajaxorg/ace/blob/v1.1.8/lib/ace/autocomplete.js#l181, making pull request first option better
