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Find packages to upgrade: cargo outdated -R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
qapitrace game.trace
apitrace dump game.trace

Understand XML: just use firefox

Markdown

For formatting:

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

Videos

# Fullscreen
ffmpeg -f x11grab -r 25 -s 1920x960 -i :0.0+0,55 -vcodec huffyuv raw.avi

ffmpeg -ss 10.0 -t 5.0 -i raw.avi -f gif -filter_complex "[0:v] fps=12,scale=1024:-1,split [a][b];[a] palettegen [p];[b][p] paletteuse" screencast.gif

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",
]

Also enable incremental builds in release mode. In ~/.cargo/config:

[build]
incremental = true

I'm not sure about setting this in the repo's Cargo.toml, because we may not want incremental builds on Github Actions for building the release? Not sure what best practice is.

git

Keep a fork up to date:

# Once
git remote add upstream https://github.com/rust-windowing/glutin/

git fetch upstream
git merge upstream/master
git diff upstream/master

Refactoring

perl -pi -e 's/WrappedComposite::text_button\(ctx, (.+?), (.+?)\)/Btn::text_fg(\1).build_def\(ctx, \2\)/' `find|grep rs|xargs`

Stack overflow

rust-gdb --args ../target/release/game --dev

Drawing diagrams

draw.io

Mapping

xodo on Android for annotating maps in the field

OSM tools

osmcha.org for recent changes

To upload diffs:

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

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

What things do I always forget to test?

DPI issues, use --scale_factor
