gdb assumes the pty/pipe descriptor is bidirectional, as you can see [here](https://github.com/bminor/binutils-gdb/blob/218bb9dcdbb8ee5a15977dc1ffe7ed7422803368/gdb/ui.c#L183). Vim, on the other hand, opens two simplex pipes for the in/out channels, hence the failure you're seeing....

I'm not an expert in ptys either, I've uploaded some code as proof of concept [here](https://github.com/LemonBoy/vim/commit/fed84233b085a8386eb467673d212deab24af3eb) to show that the gdb issue is fixed and that there's something wrong somewhere....

The quoting logic is broken, it's either not applied at all or is broken due to the use of verymagic (check `quote_meta`). I'm also not sure what verymagic is simplifying...

The problem (?) is [here](https://github.com/nim-lang/Nim/blob/cc7479b70f3f6aeb066229ab451facf3f1eff77f/compiler/sigmatch.nim#L2031), I don't know much about the sigmatch internals to suggest a solution though.

That's not true. `@export` works in every output mode, you're probably using it wrong.

Here's your exported symbol: ``` zig build-exe x.zig readelf -s foo |& grep tx ``` If you want to have your symbols exported in the dynamic symbol table: ``` zig...
