Building

EVAnalyzer is written in Rust (2024 edition) and uses Cargo as its build system.

Requirements

Tool	Version
Rust toolchain	1.80 or later
Linux system libraries (GUI)	`libinput10 libxkbcommon0 libfontconfig1 libgbm1`

Clone the repository

git clone https://github.com/evanalyzer/evanalyzer.git
cd evanalyzer

Development toolchain

rustup component add rustfmt
cargo install slint-lsp      # language server for .slint UI files
cargo install slint-viewer   # live preview of .slint files

Build targets

Linux x86-64

cargo build-linux

Windows x86-64 (cross-compile from Linux)

cargo install cargo-xwin
cargo build-win

Linux ARM64

apt install gcc-aarch64-linux-gnu
rustup target add aarch64-unknown-linux-gnu
cargo build-linux-arm

Build artifacts are placed in target/<target>/release/.

Workspace crates

The workspace is split into focused crates:

Crate	Description
`evanalyzer_core`	Image I/O (scopeio), processing algorithms, object model, pipeline execution
`evanalyzer_cfg`	Project settings, JSON serialisation, pipeline command configuration
`evanalyzer_app`	Application handle, shared project state
`evanalyzer_gui`	Slint-based desktop GUI - viewport, histogram, annotation tools, classification panel
`evanalyzer_cli`	Command-line interface for headless batch analysis
`evanalyzer_bin`	Binary entry point - launches GUI or CLI depending on arguments

Previewing the GUI inside a container

If developing inside a Docker devcontainer on Linux, allow X11 forwarding before starting the container:

xhost +local:docker

Code coverage

cargo install cargo-llvm-cov
rustup component add llvm-tools-preview

cargo llvm-cov                                    # terminal report
cargo llvm-cov --html                             # HTML report → target/llvm-cov/
cargo llvm-cov --lcov --output-path lcov.info    # lcov format (e.g. VS Code Coverage Gutters)

UI Performance Targets

Action	Target	Rationale
Pan / drag	< 10 ms	Must feel attached to the cursor
Zoom	< 16 ms	Prevents motion sickness
Channel toggle	< 100 ms	Perceived as instant
Auto-adjust	< 200 ms	Acceptable for a complex calculation
