sublimeText3插件编写教程_第一课

import sublime, sublime_plugin
import re,os

class definereplaceCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        #找到要替换的文档中include包含的文件，将他们的文件路径添加到一个list中
        starts = self.view.find_all('`include\s+"(.+)"',0)
        includes_file=[]
        #正则表达式匹配include中的文件名称。例如：`include "./define_cpu.v" 
        pattern = '`include\s+"(.+)"'
        for start in starts:
            #截取匹配到的字符串
            include_str = self.view.substr(sublime.Region(start.a,start.b))
            if re.match(pattern,include_str):
                match_include = re.search(pattern,include_str)
                include_file = match_include.group(1)
                includes_file.append(include_file)
        if len(includes_file) <1:
            return

        ###然后要做的是打开所有的include文件，并读取文件内容，将里面的define定义存成字典

        #获取当前文件的文件路径
        file_name = self.view.file_name()
        file_path = os.path.dirname(file_name)
        define_value={}
        #正则表达式匹配include文件中定义的define的值，例如define_cpu.v中的
        #`define  P_C_ADDR_1    9'b0110_0000_0 
        pattern = '`define\s+(\S+)\s+(\S+)\s'
        for include_file in includes_file:
            #获取要读取文件的完整路径
            file_full_path = os.path.join(file_path,include_file)
            with open(file_full_path,'rb') as fileReader:
                cOntent= fileReader.read()
                try:
                    cOntent= content.decode('utf-8')
                except:
                    cOntent= content.decode('gbk')

                matchs_def_val = re.findall(pattern,content)
                print(matchs_def_val) 
                for def_val in matchs_def_val:
                    define = def_val[0]
                    value  = def_val[1]
                    if len(define.strip()) >0 and len(value.strip()) >0:
                        define_value[define.strip()] = value.strip()

        ###最后是将打开文档中的define定义全部替换成真实的值

        #首先找到文档中引用的宏定义
        pattern = '`(\w+)'
        finds = self.view.find_all(pattern,0)
        startpoint = 0
        for i in range(len(finds)):
            start = self.view.find(pattern,startpoint)
            cOntent= self.view.substr(sublime.Region(start.a,start.b)).replace('`','')
            if define_value.get(content)!=None:
                #找到宏定义的位置，并从存储的define_value字典中查找真实的值，进行替换。
                self.view.replace(edit,start,define_value[content])
            else:
                startpoint = start.b
