Adding custom snippet - Document missing

[sreenadh]

Go this from https://github.com/Dahs81/ace-snippet-extension/blob/master/snippets.js

var snippetManager = ace.require("ace/snippets").snippetManager;
snippet = snippetManager.parseSnippetFile(
                "snippet hello\n" 
                + "<one_tab_indent>world"
                , "html");
snippetManager.register(snippet, "<mode>");

this worked for me:

ace-snippets-extension-simple.js

import ace from 'ace-builds'

export const registerSnippets = function(editor, session, mode, snippetText) {
    editor.setOptions({
        enableBasicAutocompletion: true,
        enableSnippets: true,
    })

    var snippetManager = ace.require('ace/snippets').snippetManager

    var id = session.$mode.$id || ''
    var m = snippetManager.files[id]

    m.scope = mode
    m.snippetText = snippetText
    m.snippet = snippetManager.parseSnippetFile(snippetText, m.scope)

    snippetManager.register(m.snippet, m.scope)
}

export const createSnippets = snippets =>
    (Array.isArray(snippets) ? snippets : [snippets])
        .map(({ name, code }) =>
            [
                'snippet ' + name,
                code
                    .split('\n')
                    .map(c => '\t' + c)
                    .join('\n'),
            ].join('\n')
        )
        .join('\n')

code:

import ace from 'ace-builds'
import { Range, EditSession } from 'ace-builds'
import 'ace-builds/src-noconflict/ext-language_tools'
import 'ace-builds/src-noconflict/mode-javascript'
import 'ace-builds/webpack-resolver'

import {
    registerSnippets,
    createSnippets,
} from './ace-snippets-extension-simple'

const editor = ace.edit(/*HTMLElement reference or css selector string*/)

// ...
// ...
// ...

editor.setOptions({
    enableBasicAutocompletion: true,
    enableSnippets: true,
    enableLiveAutocompletion: false,
})

editor.setTheme('ace/theme/monokai')
editor.session.setMode('ace/mode/javascript')

registerSnippets(
    editor,
    editor.session,
    'javascript',
    createSnippets([
        { name: 'build', code: 'console.log("build")' },
        { name: 'destroy', code: 'console.log("destroy")' },
    ])
)
