On: Inline C/Assembler in Bash

[unsignedqword]

The insane things people do in Bash sometimes...although I don't think anything can top the x86 Assembler that was written entirely in Bash:

to call this an assembler is to not give it credit where it's due - this is not an assembler, it's much more than that.

it's a set of functions for bash that when sourced make the assembly a valid bash script which then runs and assembles itself. this is genius.

It's using the shell's own tokenizer to parse asm! That's glorious!

I don't really understand why the code works since I can't read x86 asm yet, but I think how it works is reasonably clear. Each instruction has its own bash function that writes its opcodes to the output file and the asm script to be assembled is (I think) sourced directly into the running shell session.

Neat!

Click the link, and you're just a few spacebar presses away from answering that question for yourself (it's a few paragraphs down).

My favourite of the listed reasons.
