Profiling performance

Using perf:

$ perf record -g binary
$ perf script | stackcollapse-perf.pl | rust-unmangle | flamegraph.pl > flame.svg

NOTE: See @GabrielMajeri's comments below about the -g option.

Why

Ripgrep is a fast search tool like grep. It's mostly a drop-in replacement for ag, also know as the Silver Searcher.

helm-ag is a fantastic package for Emacs that allows you to display search results in a buffer. You can also jump to locations of matches. Despite the name, helm-ag works with ripgrep (rg) as well as with ag.

How

How to launch games via Proton from CLI (useful for debug)

In just 2 steps

First. Run this:

export STEAM_COMPAT_DATA_PATH=~/.local/share/Steam/steamapps/compatdata

Second. Now in the same terminal, run your game (this example: Raft)

~/.local/share/Steam/steamapps/common/Proton\ 5.13/proton run ~/.local/share/Steam/steamapps/common/Raft/Raft.exe
