I did something similar with TCL, the basis was using an extension I wrote to handle the UNIX stuff [0]. It operated an On-Premises cloud environment appliance, and `init` was just a TCL script (at one point it was a statically linked binary with the init script embedded, but that turned out to be overkill)

A very timely endeavor indeed https://devblogs.microsoft.com/typescript/typescript-native-...

Reading the code, I was surprised to see that cd was implemented by calling out to the os library. I assumed that was something the shell or at least userspace handled. At what level does the concept of a “current directory” exist?

It’s never early to prepare for JavaScript complete takeover.

Kernighan and Ritchie wept. (Tears of joy at an awesome hack, or tears of sadness at an awesome hack?)

urgh

Very cool. Good use of quickjs, although it would have been cool if it somehow didn’t need a libc and just used the syscall interface. Makes me want to give that a try.
