在 Sublime Text 中编写查找和替换操作脚本

我经常发现自己在文件中执行重复的文件和替换操作。最常见的是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 中这是理所当然的，

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。

如果可以的话，如何在 Sublime Text 编辑器中定义这样的函数，然后调用它来对当前打开的文件进行操作？

以下是编写 Sublime Text 2 插件的资源：

1. Sublime Text 2 API 参考 http://www.sublimetext.com/docs/2/api_reference.html
2. Sublime Text 2 插件示例 http://www.sublimetext.com/docs/plugin-examples
3. 如何运行 Sublime Text 2 命令 https://stackoverflow.com/questions/19532204/in-sublime-why-is-def-run-working-in-one-case-and-not-another-case-and-how-can/19533899#19533899
4. 设置 Sublime Text 2 自定义键盘快捷键 https://superuser.com/questions/492021/setting-up-sublime-text-2-custom-keyboard-shortcuts

例子：你可以写一个类似的插件，并给它绑定一个热键，即batch_edit命令。然后您可以打开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。您可以通过以下方式获取文件编码self.view.encoding().

# -*- 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)
