vim - apply substitute to a string variable in a map

Question

I have a noremap that sends the current full file path to an interpreter.

The problem is that on windows the \ need to be / -- so when i pass expand("%:p") an error is thrown.

I have figured how to do this with a string in the editing frame in vim using :s@\\@/@g, however, i cannot figure out how to apply the substitute command to the string before sending it from vim to the interpreter.

Is this possible?

Answer 1

有一个substitute()功能类似于:s：只需使用substitute(expand("%:p"), '\\', '/', 'g'). 但是，对于这种特殊的字符交换，更简单的tr()就足够了：tr(expand("%:p"), '\', '/').

实际上，一个简单的替换实际上可以expand()通过 filename-modifiers: 的一个相当模糊的特性与（感谢 Peter Rincker 的评论！）结合使用expand('%:p:gs?\\?/?')。

另外，看看:set shellslash；它可以在 Windows 上将反斜杠全局转换为正斜杠。
