Sublime Text 中的脚本查找和替换操作

Question

我经常发现自己在一个文件中执行重复的文件和替换操作。大多数情况下，这归结为 fixed 查找和替换操作；删除一些行，更改一些始终相同的字符串等等。

在 Vim 中这很简单，

function! Modify_Strength_Files()
    execute':%s/?/-/'
    execute':%s/Ä/-/'
    "--------------------------------------------------------
    execute':%s/Ä/-/'
    execute':%s///g'
    "--------------------------------------------------------
    execute':g/Version\ of\ Light\ Ship/d'
    execute':g/Version\ of\ Data\ for\ Specific\ Regulations/d'
    "--------------------------------------------------------
    " execute':g/LOADING\ CONDITION/d'
    " execute':g/REGULATION:\ A\.562\ IMO\ Resolution/d'

    " This is to reduce multiple blank lines into one.
    execute ':%s/\s\+$//e'
    execute ':%s/\n\{3,}/\r\r/e'
    " ---------------------
endfunction

逐字复制。

如果可以在 Sublime Text 编辑器中定义这样的函数，然后调用以对当前打开的文件执行操作，那么如何在 Sublime Text 编辑器中定义？

这里是编写 Sublime Text 2 插件的资源：

1. Sublime Text 2 API Reference
2. Sublime Text 2 Plugin Examples
3. How to run Sublime Text 2 commands
4. Setting up Sublime Text 2 Custom Keyboard Shortcuts

例子：你可以写一个类似的插件，给它绑定一个热键，即batch_edit命令。然后您可以打开一个文件并通过该热键执行命令。顺便说一句，在这个脚本中，我没有考虑文件编码。您可以通过self.view.encoding()获取文件编码。

# -*- coding: utf-8 -*-

import sublime, sublime_plugin

import re

class BatchEditCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        self._edit = edit
        self._replace_all(r"\?", "-")
        self._replace_all(u"Ä", "-")
        self._delete_line_with(r"Version of Light Ship")
        self._delete_line_with(r"Version of Data for Specific Regulations")
        self._replace_all(r"(\n\s*\n)+", "\n\n")

    def _get_file_content(self):
        return self.view.substr(sublime.Region(0, self.view.size()))

    def _update_file(self, doc):
        self.view.replace(self._edit, sublime.Region(0, self.view.size()), doc)

    def _replace_all(self, regex, replacement):
        doc = self._get_file_content()
        p = re.compile(regex, re.UNICODE)
        doc = re.sub(p, replacement, doc)
        self._update_file(doc)

    def _delete_line_with(self, regex):
        doc = self._get_file_content()
        lines = doc.splitlines()
        result = []
        for line in lines:
            if re.search(regex, line, re.UNICODE):
                continue
            result.append(line)
        line_ending = {
            "Windows" : "\r\n",
            "Unix"    : "\n",
            "CR"      : "\r"
        }[self.view.line_endings()]
        doc = line_ending.join(result)
        self._update_file(doc)
