自定义自动完成程序和句点 (.) [英] Custom autocompleter and periods (.)

问题描述

当使用自定义前缀提取正则表达式 identifierRegexps

I can't seem to make getCompletions function to trigger in my custom completer when using custom prefix extraction regex identifierRegexps

基本上，我正在尝试创建一个自动完成程序，它将在以字母开头的句点 (.) 上触发.例如.在foo"中.当输入句号时，我想展示我的自定义建议.

Basically I am trying to create an autocompleter which will trigger on periods (.) preceded by letters. E.g. In "foo." when the period is typed I would like to present my custom suggestions.

var lang = ace.require("ace/ext/language_tools");
var editor = ace.edit("editor");
editor.getSession().setMode("ace/mode/javascript");
editor.setOptions({
  enableBasicAutocompletion: true,
  enableSnippets: true,
  enableLiveAutocompletion: true
});

var compl = {
  identifierRegexps: [/[a-zA-Z_0-9.$-u00A2-uFFFF]/],
  getCompletions: function (editor, session, pos, prefix, callback) {
    alert(prefix);

    callback(null, []);
    return;
  }
}
lang.addCompleter(compl);

使用上述代码段，输入点时会出现建议弹出窗口，但 getCompletions 不会触发.但是，它确实会在任何其他字符上触发.

With the above snippet, suggestions popup appears when typing a dot but getCompletions doesn't trigger. However, it does trigger on any other character.

更新:

在使用

lang.setCompleters();

使 getCompletion 函数触发.但是在这种情况下 prefix 参数是空的.

makes the getCompletion function to trigger. However prefix argument is empty in that case.

推荐答案

通过修改language_tools.js中的ID_REGEX var成功解决.

Managed to solve it by modifying the ID_REGEX var in language_tools.js.
