Calculator REPL, similar to bc(1)

命令和别名

  • eva

历史

项目历史与用法

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

项目历史

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.

采用历史

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.

使用方式

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.

为什么软件包爱好者会关心

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.
