如何在Ace编辑器中以编程方式添加代码段? [英] How do I programmatically add a snippet in Ace Editor?
问题描述
我想将自己的自定义代码段添加到ace编辑器输入框中。
我将如何添加它们?
来自有关代码段的Ace编辑器:
当前,这是向项目添加自定义代码段的唯一方法是创建一个插件(如此处所述)。
我看到了一个名为 ace-snippet-extension ,但自2016年以来未进行过更新,除了简单地允许我添加一个代码段之外,它还做了很多其他事情。 p>
此外,我使用的是ES6 + / ES2015 +,因此require语句也令人困惑。
这是结果我正在寻找:

后显示文本 build的摘要建议经过研究,我从ace-snippet-extension中提取了有用的位。另一个棘手的部分是,代码片段似乎需要某种类型的缩进,这是我为之准备的功能(但是未经充分测试)
此处是库的代码,名为 ace-snippets-extension-simple.js
:
从'ace-builds'中导入ace
导出const registerSnippets = function(editor,session,mode,snippetText){
editor.setOptions({
enableBasicAutocompletion:true,
enableSnippets:true,
})
var snippetManager = ace.require('ace / snippets')。snippetManager
var id = session。$模式。$ id || ''
var m = snippetManager.files [id]
m.scope =模式
m.snippetText = snippetText
m.snippet = snippetManager.parseSnippetFile(snippetText ,m.scope)
snippetManager.register(m.snippet,m.scope)
}
export const createSnippets = snippets =>
(Array.isArray(snippets)?代码段:[代码段])
.map(({{name,code})= >>
[
'snippet'+名称,
代码
.split('\n')
.map(c =>'\t'+ c)
.join('\n') ,
] .join('\n')
)
.join('\n')
以下是消费者代码的示例:
使用此代码导入以上内容。
从'ace-builds'导入ace
import {Range,EditSession}从'ace-builds'
import'ace -builds / src-noconflict / ext-language_tools'
import'ace-builds / src-noconflict / mode-javascript'
import'ace-builds / webpack-resolver'
从'./ace-snippets-extension-simple'
const editor = ace.edit(/ * HTMLElement)导入{
registerSnippets,
createSnippets,
}参考或CSS选择器字符串* /)
// ...
// ...
// //
editor.setOptions({
enableBasicAutocompletion:true,
enableSnippets:true,
enableLiveAutocompletion :false,
})
editor.setTheme('ace / theme / monokai')
editor.session.setMode('ace / mode / javascript')
registerSnippets(
编辑器,
editor.session,
'javascript',
createSnippets([
{name:'build',code:' console.log( build)'},
{名称:'destroy',代码:'console.log( destroy)'},
])
)
I want to add my own custom code snippets to my ace editor input box.
How would I go about adding them?
From the documentation of Ace editor regarding snippets:
Currently, the only way to add custom snippets to a project is to create a plugin (as described here).
I saw a project called ace-snippet-extension but it has not been updated since 2016, and does more things than simply allowing me to add a snippet.
Additionally, I am using ES6+/ES2015+, so the require statements are confusing as well.
This is the result I'm looking for:
After some research, I extracted the useful bits out of the ace-snippet-extension. Another tricky part is that snippets seem to require a certain type of indentation, which I've made a function for (not well-tested however)
Here is the 'library' code, named 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')
Here is an example of the "consumer" code:
Use this to import the above.
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")' },
])
)
