When the `args.exe` or `args.libc` arguments are missing, look for the files in the current working directory. This allows to quickly get a template by just running `pwn template` (and maybe --host --port for remote instances). This is inspired by https://github.com/io12/pwninit

Allow to keep the old static template behavior.

There was a problem hiding this comment.
Idea for the future: more and more challenges ship a Dockerfile or even docker-compose. We could use it to detect needed libraries and a binary as well maybe (using API like we do with ADB or shelling out to docker cli).
Check about common name patterns instead of plainly the presence of "libc" in the name. Co-authored-by: Arusekk <[email protected]>

When the
args.exeorargs.libcarguments are missing, look for the files in the current working directory.This allows to quickly get a template by just running
pwn template(and maybe--host+--portfor remote instances) and have the arguments filled in automatically. Less typing - more pwning!This is inspired by https://github.com/io12/pwninit
