Development notes

Find packages to upgrade: cargo outdated -R

Deal with compile tile: cargo bloat --time

Find why two binary crates aren't sharing dependencies: https://old.reddit.com/r/rust/comments/cqceu4/common_crates_in_cargo_workspace_recompiled/

Where's a dependency coming from? cargo tree -i -p syn

Diff screencaps: http://www.imagemagick.org/Usage/compare/#methods

Debug OpenGL calls:

apitrace trace --api gl ../target/debug/game ../data/input/raw_maps/montlake.bin
qapitrace game.trace
apitrace dump game.trace

Understand XML: just use firefox

Profiling

Actually, https://github.com/flamegraph-rs/flamegraph is pretty cool too.

apt-get install google-perftools libgoogle-perftools-dev

Follow Usage from https://crates.io/crates/cpuprofiler

Modify game/Cargo.toml to include the profiler feature on ezgui. Then run game or headless with --enable_profiler

google-pprof --no_strip_temp ../target/debug/game profile
google-pprof --no_strip_temp ../target/release/headless profile
top30 --cum

Building releases

Cross-compilation notes: https://github.com/rust-embedded/cross Or use https://github.com/japaric/trust

Initially have to:

cargo install cross
sudo apt-get install docker.io
sudo usermod -aG docker ${USER}

Then:

sudo systemctl start docker
cross build --release --target x86_64-pc-windows-gnu --bin game
wine target/x86_64-pc-windows-gnu/release/game.exe data/system/maps/montlake.bin

Markdown

For formatting:

sudo apt-get install npm
cd ~; mkdir npm; cd npm
npm init --yes
npm install prettier --save-dev --save-exact

Use https://github.com/joeyespo/grip to render. Doesn't seem to work with the graphviz image.

JOSM

java -jar ~/Downloads/josm-tested.jar ~/abstreet/map_editor/diff.osc

Press (and release T), then click to pan. Download a relevant layer, select the .osc, merge, then upload.

Faster linking

sudo apt-get install lld

Stick this in ~/.cargo/config:

[target.x86_64-unknown-linux-gnu]                                                                   
rustflags = [                                                                                       
    "-C", "link-arg=-fuse-ld=lld",                                                    
]
