在Sublime Text中编写查找和替换操作的脚本

Question

我经常发现自己在文件中执行重复文件和替换操作.大多数情况下归结为固定查找和替换操作; 删除一些行,更改一些始终相同的字符串等等.

在Vim中,这是一个不用脑子的事,

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.

如何在Sublime Text编辑器中定义这样的函数,如果它可以完成,然后调用以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
2. Sublime Text 2插件示例
3. 如何运行Sublime Text 2命令
4. 设置Sublime Text 2自定义键盘快捷键

示例:您可以编写类似的插件并将热键绑定到它,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)
