如何编辑内置命令行为 [英] How to edit built in command behavior

问题描述

我想编辑 find_under_expand (ctrl+d) 以将带连字符的单词视为单个单词.因此，当我尝试替换 var a 的所有实例时，它不应该匹配 a-b 之类的单词中的a"子字符串，而它目前确实如此.

I want to edit find_under_expand (ctrl+d) to consider hyphenated words, as single words. So when I try to replace all instance of var a, it shouldn't match substrings of "a" in words like a-b, which it currently does.

我假设 find_under_expand 将您当前的选择包裹在这样的正则表达式边界中:\ba\b

I'm assuming find_under_expand wraps your current selection in regex boundaries like this: \ba\b

我需要用这样的方式包装它:\b(?<!-)a(?!-)\b

I need it to wrap in something like this: \b(?<!-)a(?!-)\b

find_under_expand 命令的源是否可以编辑?还是我必须重写整个事情?我不知道从哪里开始.

Is the find_under_expand command's source available to edit? Or do I have to rewrite the whole thing? I'm not sure where to begin.

推荐答案

Sublime 的命令以以下几种方式之一实现:如 宏，如插件，并在内部作为编译程序的一部分(可能作为 C++).默认的宏和插件可以在 ST2 的 Packages/Default 目录中找到(其中 Packages 是选择 Preferences -> Browse 时打开的目录Packages...)，或压缩在 ST3 中的 Installed Packages/Default.sublime-package 文件中，使用@skuroda 的优秀PackageResourceViewer 插件，可通过包控制获得.宏具有 .sublime-macro 扩展名，而插件是用 Python 编写的并具有 .py 扩展名.

Sublime's commands are implemented in one of several ways: as macros, as plugins, and internally as part of the compiled program (probably as C++). The default macros and plugins can be found in the Packages/Default directory in ST2 (where Packages is the directory opened when selecting Preferences -> Browse Packages...), or zipped in the Installed Packages/Default.sublime-package file in ST3, extractable using @skuroda's excellent PackageResourceViewer plugin, available via Package Control. Macros have .sublime-macro extensions, while plugins are written in Python and have .py extensions.

我在 ST3 中搜索了所有 Defaults 包(事情通常与 ST2 中的相同)，但找不到包含的宏或 .py 文件find_under_expand 命令或 FindUnderExpand，这是在插件中命名命令类时的约定.因此，我强烈怀疑这个命令是 Sublime 的内部命令，可能是用 C++ 编写的并链接到可执行文件或 .dll|.dylib|.so 库中.

I searched all through the Defaults package in ST3 (things are generally the same as in ST2), and was unable to find a macro or .py file that included the find_under_expand command, or FindUnderExpand, which is the convention when naming command classes in plugins. Therefore, I strongly suspect that this command is internal to Sublime, probably written in C++ and linked into the executable or in a .dll|.dylib|.so library.

所以，看起来没有一个现有文件可以轻松修改以适应您的负面前瞻/后视模式(我认为这就是那些，我的正则表达式有点生疏......).相反，您必须从头开始实现自己的插件，读取设置文件中的 "word_separators" 值，而 find_under_expand 的当前实现似乎没有正在做，从你的上一个问题来看和我自己的测试.从理论上讲，这应该不会太困难 - 您可以打开一个快速面板，用户可以在其中输入要搜索的模式/正则表达式，并且您可以遍历当前视图以查找匹配项并突出显示/选择它们.

So, it doesn't look like there's an existing file that you could easily modify to adjust for your negative lookahead/lookbehind patterns (I assume that's what those are, my regex is a bit rusty...). Instead, you'll have to implement your own plugin from scratch that reads the "word_separators" value in your settings file, which the current implementation of find_under_expand doesn't seem to be doing, judging from your previous question and my own testing. Theoretically, this shouldn't be too terribly difficult - you can just open up a quick panel where the user enters the pattern/regex to be searched for, and you can just iterate through the current view looking for matches and highlighting/selecting them.
