TL;DR
I am trying to manually trigger ace editor snippets through a function call, rather than the conventional approach (keyboard keys).
Explanation
I need a function that takes in the editor and a snippet string as the parameters, and adds that snippet to the editor. function addSnippet(editor, snippet)
.
Ace editor supports TextMate-ish snippets.
if (${1:condition_name}) {
${2:body}
}
So when we call this function, it should add the snippet, highlight the snippet markers and select the first one. After filling the first one and hitting tab, the editor should move to the next snippet marker. Just like in the Kitchen Sink example (but I want to add/trigger snippets via a function call instead).
I tried hacking my way through and made this function. But it's messy and incomplete (doesn't support markers and tab presses). Is there any native method for this? I've seen a few examples using snippetManager
, but they use keyboard triggers, not manual functions.
Any help regarding this issue would be appreciated. Thanks.
With a code file open in the editor, choose Snippets > Insert Snippet from the right-click menu, then My Code Snippets. You should see a snippet named Square Root. Double-click it. The snippet code is inserted in the code file.
After hours of hacks and research, I finally came across the insertSnippet
function of snippetManager
in ext-language_tools.js
, it works this way:
var snippetManager = ace.require("ace/snippets").snippetManager;
snippetManager.insertSnippet(editor, snippet);
Pretty easy actually, couldn't find it earlier due to lack of documentation.
If you don't use RequireJS then the following syntax works as well:
ace.config.loadModule('ace/ext/language_tools', function () {
editor.insertSnippet(snippetText);
});
