崇高插件:查找并选择文本 [英] sublime plugin: find and select text

问题描述

我有一个sublime text 3插件，它允许我将光标移动到其编号所在的行:

I got plugin for sublime text 3 that let me move cursor to line by its number:

import sublime, sublime_plugin

class prompt_goto_lineCommand(sublime_plugin.WindowCommand):

    def run(self):
        self.window.show_input_panel("Goto Line:", "", self.on_done, None, None)
        pass

    def on_done(self, text):
        try:
            line = int(text)
            if self.window.active_view():
                self.window.active_view().run_command("goto_line", {"line": line} )
        except ValueError:
            pass

class go_to_lineCommand(sublime_plugin.TextCommand):

    def run(self, edit, line):
        # Convert from 1 based to a 0 based line number
        line = int(line) - 1

        # Negative line numbers count from the end of the buffer
        if line < 0:
            lines, _ = self.view.rowcol(self.view.size())
            line = lines + line + 1

        pt = self.view.text_point(line, 0)

        self.view.sel().clear()
        self.view.sel().add(sublime.Region(pt))

        self.view.show(pt)

我想对其进行改进，以使光标移动到包含指定字符串的第一行.就像在文件上搜索一样: 例如，如果传递给它，则字符串"class go_to_lineCommand"插件必须将光标移至第17行:

I want to improve it to let me move cursor to first line containing the specified string. It is like a search on file: For example if pass to it string "class go_to_lineCommand" plugin must move cursor to line 17 :

，并可能选择字符串class go_to_lineCommand.

问题被简化为找到regionWithGivenString，然后我可以选择它:

The problem is reduced to finding regionWithGivenString, and then I can select it:

self.view.sel().add(regionWithGivenString)

但是不知道获取regionWithGivenString的方法.

But don't know method to get regionWithGivenString.

我试图

1. 在Google上查找: api

1. find on google: sublime plugin find and select text
2. check api

但仍然没有结果.

推荐答案

我不确定这种典型方法.但是，您可以通过以下方式实现此目的:

I am not sure about the typical way. However, you can achieve this in following way:

1. 获取当前文档的内容.
2. 搜索目标字符串以找出其开始和结束位置.现在您有了起点和终点.
3. 将Region(start, end)添加到选择中.

1. Get the content of current doc.
2. Search target string to find out its start and end position. Now you have the start and end point.
3. Add the Region(start, end) to selections.

示例:

def run(self, edit, target):
    if not target or target == "":
        return

    content = self.view.substr(sublime.Region(0, self.view.size()))
    begin = content.find(target)
    if begin == -1:
        return
    end = begin + len(target)
    target_region = sublime.Region(begin, end)
    self.view.sel().clear()
    self.view.sel().add(target_region)
