我如何 grep/pipe/redirect tsc(TypeScript 编译器)的输出?
How can I grep/pipe/redirect the output of tsc (TypeScript compiler)?
我的项目包含一个非常简单的 index.ts
:
const answer: 42 = 43;
如果我编译它,我会得到一个预期的类型错误(带有颜色;此处未显示):
$ tsc
index.ts:1:7 - error TS2322: Type '43' is not assignable to type '42'.
1 const answer: 42 = 43;
~~~~~~
Found 1 error.
假设我想 grep 查找类型错误:
$ tsc | grep "const answer"
我没有得到任何结果。难怪:
$ tsc | wc -l
1
$ tsc | cat
index.ts(1,7): error TS2322: Type '43' is not assignable to type '42'.
重定向没有帮助:
$ tsc 2>&1 | wc -l
1
$ tsc 2>&1 | cat
index.ts(1,7): error TS2322: Type '43' is not assignable to type '42'.
如何在终端中访问 tsc
的完整输出?
使用--pretty
标志:
$ tsc --pretty | grep "const answer"
1 const answer: 42 = 43;
(注意"--pretty
output is not meant to be parsed",慎用。)
它是这样工作的:
$ tsc --pretty false
index.ts(1,7): error TS2322: Type '43' is not assignable to type '42'.
$ tsc --pretty true
index.ts:1:7 - error TS2322: Type '43' is not assignable to type '42'.
1 const answer: 42 = 43;
~~~~~~
Found 1 error.
默认开启,"unless piping to another program or redirecting output to a file".
您也可以在 tsconfig.json
:
中指定
{
"compilerOptions": {
"pretty": true,
},
}
