DotSlash Windows Shim

The DotSlash Windows Shim aims to workaround the fact that Windows does not support shebangs and depends on a file's extension to determine if it is executable.

How to use it

Place the DotSlash Windows Shim executable next to a DotSlash file with the same file name as the DotSlash file plus the .exe extension. For example, if the DotSlash file is named node, copy the shim executable as node.exe into the same directory as node. When node.exe is run, it will run dotslash with the sibiling DotSlash file, and forward all arguments and IO streams.

How it works

The DotSlash Windows Shim does this:

  • Gets it own executable name (e.g. C:\dir\node.exe) and removes the extention (e.g. C:\dir\node).
  • It takes this path, plus whatever arguments were passed, and runs dotslash C:\dir\node arg1 arg2 ....
  • Waits to exit and forwards the exit code.

Binary size

The current "reference implementation" is rather large. A no_std version that uses only Windows APIs will be added soon. Stay tuned!
