所以我想将每个#
替换为whitespace on the end of line
,将每个@
替换为@
,但我的程序不会终止它只写aTAB
时为a
输入我给了%{
#include<stdio.h>
int yylex();
%}
%%
^[[:space:]]* printf("#");
([:space:]*)$ printf("@");
%%
int main() {
yylex();
}
,就像带有空格的符号$
一样。
from googleapiclient import smaple_tools
我刚刚开始学习flex,我觉得有点困惑,public _dSubject: BehaviorSubject<any> = new BehaviorSubject(null);
autorefresh(filterObj) {
return Observable.timer(60000).subscribe(() => this.callAPI());
}
callAPI() {
const url = this.endpointURL + '/xyz';
this.subscription = this.http.post(url, filterObj, this.headerObj)
.map((res: Response) => {
let response = res.json();
return response;
})
.subscribe(
response => {
this._dSubject.next(response);
},
error => (this.handleError(error))
);
}
符号如何工作,不应该检查行尾的模式?谢谢你的帮助
