[手搓人]大战[高亮编辑器/查找替换/函数跳跳蛙]--巅峰对决(1)

战前准备

github以及它的访问权限
强大的心理支撑
一点点英文水平(至少会念ABC )
会写测试样例
面向对象要学好(没学真的会感到是在地狱)

使用环境

python 3.8.0
pyqt 5.15.9
pycharm 2021.3

基础类

基本上在这两个类反复横跳

QsciScintilla
QTextEdit

这是大爹但又没完全是

跟着github上的代码走就没问题…

查找替换

因为那个重写的QsciScintilla类里有自带的查找findFirst、替换函数replace，但是它并没有说明书，所以又遇到对手了。接下来就需要我们学会自己克服困难，比如说把参数爬下来，丢给大爹让它分析，然后我再自己写一些特殊逻辑。

提前说明：

findFirst
这个函数有多个参数，传入的方式除了关键词之外，都是bool值，我分析得到的结果如下:

def search_interface(self, keyword, *state):"""obj = QsciScintilla()flag = obj.findFirst(self,expr,re,cs,wo,wrap,forward,line,index,show,posix,cxx11)->bool:param keyword: 你的关键词:param state: 元组(***)tips -> [虽然是 Any 但默认写 bool]expr: Any, --> 匹配词 keywordre: Any, --> 是否使用正则表达式匹配 -> 默认向后搜索 regexpcs: Any, --> 是否区分大小写匹配wo: Any, --> 是否匹配整个关键词 --> 不需要完整匹配 --> Falsewrap: Any, --> 是否在匹配结束之后回到搜索起点 --> 默认是 Trueforward: bool, --> 向前搜索: False, 向后搜索: True; 一般是True即向后搜索... 这里注意不要搞反line: -1, --> 搜索的起始行号 表示从当前行开始... 0~Nindex: -1, --> 搜索的起始索引 表示从当前行的当前光标开始 0~Nshow: True, --> 是否显示搜索结果 默认高亮...显示posix: False, --> 是否使用POSIX正则表达式匹配 默认Falseusername: False, --> 是否用用户名模式匹配 我的用户名: cxx11:return: bool --> 返回一个布尔值 表明是否找到..."""return self.__editor.findFirst(keyword, *state)  # bool

replace
这个是必须在选中的情况下使用，首先用findFirst查找选中关键词，让这些关键词处于选中状态，然后直接用self.__editor.replace(replace_word)就自动替换完成，注意是选中状态有几个替换几个。

参数说明

区分大小写：就是根据大小写来匹配，如果输入一个全部大写的是不会匹配到小写内容的。
全部匹配：就是必须严格是那个关键词，res只能匹配res不能匹配res1
正则表达式匹配：根据你输入的关键词得到那个关键词的正则表达式，根据它再查找匹配其他字符。
是否回到搜索起点：默认搜索起点是光标停留处，若不回到就不会循环查找/替换光标范围之外的。
向前/先后搜索：相对于光标停留位置向前或者向后，True是向后
搜索行号：默认-1 默认从第一行，可以自定义，0~N-1
搜索下标：默认-1 默认第一行第一个开始，可以自定义,0~N-1
默认返回值是bool，代表在特定位置上是否找到

范围书写

这里由于替换很简单，只写搜索
替换就是在搜索基础上替换
全部搜索：

干货干得要缺水了！
语法树到时候更是重量级…

任重而道远…

不知不觉竟然写了这么多代码（嗐）
如果付出和收获对等，我也能成为最强吗？
