Music Hoard

Developing

Pre-requisites

musicbrainz-api

This feature requires the openssl system library.

On Fedora:

sudo dnf install openssl-devel

Usage notes

Text selection

To select and copy text use the terminal-specific modifier key (on Linux this is usually the Shift key).

Code Coverage

Pre-requisites

rustup component add llvm-tools-preview
cargo install grcov

Generating Code Coverage

env CARGO_TARGET_DIR=codecov \
    rm -rf ./codecov/debug/{coverage,profraw}
env CARGO_TARGET_DIR=codecov \
    cargo clean -p musichoard
env RUSTFLAGS="-C instrument-coverage" \
    LLVM_PROFILE_FILE="codecov/debug/profraw/musichoard-%p-%m.profraw" \
    CARGO_TARGET_DIR=codecov \
    BEETSDIR=./ \
    cargo test --all-features --all-targets
grcov codecov/debug/profraw \
      --binary-path ./codecov/debug/ \
      --output-types html \
      --source-dir . \
      --ignore-not-existing \
      --ignore "build.rs" \
      --ignore "examples/*" \
      --ignore "tests/*" \
      --ignore "src/main.rs" \
      --ignore "src/bin/musichoard-edit.rs" \
      --excl-line "^#\[derive" \
      --excl-start "GRCOV_EXCL_START|mod tests \{" \
      --excl-stop "GRCOV_EXCL_STOP" \
      --output-path ./codecov/debug/coverage/
xdg-open codecov/debug/coverage/index.html

Note that some changes may not be visible until codecov/debug/coverage is removed and the grcov command is rerun.

For most cases cargo clean can be replaced with rm -rf ./codecov/debug/{coverage,profraw}.

Benchmarks

Pre-requisites

rustup toolchain install nightly
