go-wsllinks

Like a symlink for a binary inside WSL 2

How it works

Proxy application calls selected binary inside specified WSL 2 distro.

Application loads 2 ini files relative to itself:

Supported properties:

mode - optional, operation mode, currently supported "wsl" (default) or "direct";
distro - mandatory, "wsl" mode only, name of the WSL distro, can't be empty;
user - optinonal, "wsl" mode only, user name to use, if skipped then will use default user configured by WSL 2;
shellType - optional, "wsl" mode only, supported types are "standard", "login", "none", if missing then command will be executed with --exec argument;
binary - optional, should be equal to <binary-name-no-ext> or absolute path of the form /some/path/<binary-name-no-ext> in "wsl" mode or absolute or relative path in Windows format in direct mode;
baseDir - optional, "direct" mode only, should be absolute path, sets base dir for binary lookup, if missing then current executable dir is used as a base.

To output release information from distro named Ubuntu and user named user:

Build the app:

go build

Rename it to macth cat command:

move go-wsllinks.exe cat.exe

Prepare config:

echo distro = Ubuntu > cat.ini
echo user = user >> cat.ini

Call the command:

cat /etc/os-release

To output information from default msys2 installation:

Build the app:

go build

Rename it to macth uname command:

move go-wsllinks.exe uname.exe

Prepare config:

echo mode = direct > uname.ini
echo binary = C:\msys64\usr\bin\uname.exe >> uname.ini

Call the command:

uname -a
