匹配* .ts但不匹配* .d.ts的Webpack正则表达式测试 [英] Webpack regex test that matches *.ts but not *.d.ts

问题描述

我正在使用Webpack(2.3.3)在TS中构建我的Aurelia应用.但是，由于我对AureliaPlugin(2.0.0-rc.2)使用了includeAll选项，因此ts-loader(2.0.3)会询问d.ts文件，该文件没有导出，也没有输出.

I am using Webpack (2.3.3) to build my Aurelia app in TS. However, since I am using includeAll option for AureliaPlugin (2.0.0-rc.2), ts-loader (2.0.3) cries about d.ts files that has nothing exported emitting no output.

这是我对ts文件的规则:{ test: /\.ts$/, include: /ClientApp/, use: "ts-loader" }

here is my rule for ts files: { test: /\.ts$/, include: /ClientApp/, use: "ts-loader" }

我需要更改测试值，使其与名为* .ts的文件匹配，但* .d.ts除外.你能帮我吗?

I need to change the test value in a way that it matches files named *.ts except *.d.ts. Can you help me please?

注意:我看到已经有一个类似的正则表达式问题，但是这个问题对我不起作用.

Note: I see there is already a similar regex question but that one did not work for me.

推荐答案

正则表达式匹配末尾带有.ts而不是.d.ts的字符串是

A regex that matches strings with .ts at the end but not .d.ts is

/(^.?|\.[^d]|[^.]d|[^.][^d])\.ts$/

参见 regex演示.这是一个POSIX样式表达式，可与任何正则表达式引擎一起使用.

See a regex demo. It is a POSIX style expression that will work with any regex engine.

详细信息

• (^.?|\.[^d]|[^.]d|[^.][^d])-以下任一项:
  • ^.?-字符串开头+任何可选的字符
  • \.[^d]-点和除d
  之外的任何字符
  • [^.]d-除.和d
  之外的任何字符
  • [^.][^d]-除.外的任何字符，然后除d外的任何字符(这样，我们匹配除.d之外的所有字符)
  • (^.?|\.[^d]|[^.]d|[^.][^d]) - either of:
    • ^.? - start of string + any optional char
    • \.[^d] - a dot and any char but d
    • [^.]d - any char but . and d
    • [^.][^d] - any char but . and then any char but d (this way, we match all but .d)

    或者，使用基于前瞻性的解决方案:

    Alternatively, use a lookahead based solution:

    /^(?!.*\.d\.ts$).*\.ts$/
    

    请参见另一个演示

    详细信息:

    • ^-字符串开头
    • (?!.*\.d\.ts$)-字符串不能以.d.ts
    结尾
    • .*-最多0个字符，直到
    • \.ts$-.ts在字符串的末尾.
    • ^ - start of string
    • (?!.*\.d\.ts$) - the string cannot end with .d.ts
    • .* - any 0+ chars up to the
    • \.ts$ - .ts at the end of the string.

    但是，您可能会探索此SO线程中所述的另一个选项.
