fnm_rust

An experimental Rust implementation of fnm

Testing

The tests should be written in a DSL that will generate tests for every shell we support.

Windows Support

I'm working on it. I want everything to be well-tested.

The shell initialization script in Windows looks like:

FOR /f "tokens=*" %i IN ('fnm env --use-on-cd') DO CALL %i

PowerShell is:

fnm env --use-on-cd | Out-String | Invoke-Expression

Process listing

We can get the pid and parent pid by running the following command:

wmic process get processid,parentprocessid,executablepath /format:csv

We will get back a CSV that looks like:

Node,ExecutablePath,ParentProcessId,ProcessId
WINDEV2007EVAL,,0,0
WINDEV2007EVAL,,0,4
WINDEV2007EVAL,,4,72
WINDEV2007EVAL,,4,332
WINDEV2007EVAL,,416,424
WINDEV2007EVAL,,416,492
WINDEV2007EVAL,,484,500
WINDEV2007EVAL,C:\Windows\system32\winlogon.exe,484,548
WINDEV2007EVAL,,492,612
WINDEV2007EVAL,C:\Windows\system32\lsass.exe,492,620
WINDEV2007EVAL,C:\Windows\system32\fontdrvhost.exe,492,712
WINDEV2007EVAL,C:\Windows\system32\fontdrvhost.exe,548,720
...

Then we can parse it with Serde and traverse everything in-memory to look for the binary!
