## Projektgeschichte und Nutzung

eva is a Rust calculator REPL and command-mode calculator similar to `bc(1)`.

### Projektgeschichte

The official repository was created in 2019. Its README describes eva as a simple calculator REPL with syntax highlighting and persistent history, and Cargo metadata classifies it under command-line, science, and parser categories.

### Adoptionsgeschichte

The official README documents installation through Homebrew, crates.io, and manual source builds. The input package facts list packages for Homebrew, Alpine, MacPorts, Nix, Arch/Pacman, and Scoop.

### Wie es verwendet wird

eva can be launched as an interactive REPL or passed an expression argument for command mode. It supports arithmetic operators, constants, trigonometric and logarithmic functions, output radix and precision options, previous-answer reuse, syntax highlighting, and persistent REPL history.

### Warum Paket-Nerds sich dafür interessieren

eva is a small terminal calculator in the lineage of `bc`, interesting to package maintainers because it is a Rust CLI distributed through crates.io and several system package managers while keeping a focused single-binary interface.
