# Repository instructions
## Gitea issue workflow
Use the `tea` command-line tool as the preferred way to list, inspect, create,
and update Gitea issues. Run it from the repository root so it can use the
configured remote, for example `tea issues` or `tea issues 1`.
## Required pre-commit gates
Run every gate below from the repository root before committing. Every command
must succeed; do not commit code that is unformatted, fails Clippy, or compiles
with warnings.
```sh
cargo fmt --all -- --check
RUSTFLAGS="-D warnings" cargo check --workspace --all-targets
cargo clippy --workspace --all-targets -- -D warnings
cargo test --workspace
```
Do not weaken or skip these gates to make a commit pass. Fix the underlying
warning, lint, formatting issue, or test failure.
## iOS simulator build and deployment
This Apple Silicon project builds the simulator app for `arm64`. Do not disable
code signing: the Rust build script consumes Xcode's generated simulator
entitlement paths. Do not request an `x86_64` simulator build unless the
`x86_64-apple-ios` Rust target has explicitly been installed.
Use this sequence from the repository root:
```sh
cd ios
xcodegen generate
xcodebuild \
-project Gotcha.xcodeproj \
-scheme Gotcha \
-configuration Debug \
-sdk iphonesimulator \
-destination 'platform=iOS Simulator,name=iPhone 17 Pro' \
ARCHS=arm64 \
ONLY_ACTIVE_ARCH=YES \
build
gotcha_build_dir="$(
xcodebuild \
-project Gotcha.xcodeproj \
-scheme Gotcha \
-configuration Debug \
-sdk iphonesimulator \
-destination 'platform=iOS Simulator,name=iPhone 17 Pro' \
-showBuildSettings -json \
ARCHS=arm64 \
ONLY_ACTIVE_ARCH=YES |
plutil -extract 0.buildSettings.TARGET_BUILD_DIR raw -o - -
)"
xcrun simctl install booted "$gotcha_build_dir/Gotcha.app"
xcrun simctl launch booted de.rfc1437.gotcha
```
Before deploying, check for a booted simulator with
`xcrun simctl list devices available`. If none is booted, boot an available
iPhone (currently `xcrun simctl boot "iPhone 17 Pro"`) and open Simulator.
CoreSimulator access may require running `xcodebuild` and `simctl` outside the
workspace sandbox.
## Generated build data
Use Xcode's default DerivedData location; do not pass `-derivedDataPath`.
Cargo's ignored `target/` directory is a disposable build cache. Cargo does not
bound or garbage-collect stale target artifacts, so check it with
`du -sh target` and run `cargo clean` when disk space is worth a full rebuild.
Do not add a custom cache-pruning tool or disable incremental compilation just
to reduce routine cache usage.
