# 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Find packages to upgrade: `cargo outdated -R`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
|
|
|
|
`apt-get install google-perftools libgoogle-perftools-dev`
|
|
|
|
Follow Usage from https://crates.io/crates/cpuprofiler
|
|
|
|
Modify `editor/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:
|
|
|
|
```shell
|
|
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.
|
|
|
|
https://github.com/ekalinin/github-markdown-toc for table of contents (stashed
|
|
in ~/Downloads/gh-md-toc)

## Videos
|
|
|
|
```
|
|
# Fullscreen
|
|
ffmpeg -f x11grab -r 25 -s 1920x1080 -i :0.0 -vcodec huffyuv raw.avi
|
|
# Default window
|
|
ffmpeg -f x11grab -r 25 -s 1800x800 -i :0.0+28,92 -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
|

```
|
|
|
|
## 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",
|
|
]
|
|
```
