werds

A simple program that counts the number of words in the specified file(s).

Intention

A learning exercise in building a wc-esque program in Rust.

Attempts to follow the Command Line Interface Guidelines (clig) as best as possible.

Usage

A single file can be passed in:

$ werds path/to/file.md 22

Or pass in a collection of files:

$ werds tests/fixtures/*.txt tests/fixtures/haiku.txt: 7 tests/fixtures/long.txt: 204 tests/fixtures/medium.txt: 8 total: 219

Or pipe in data from stdin with the - file arg:

$ echo "Nothing quite like a fresh cup of tea\!" | werds - 8

stdin can be compiled with other files:

$ echo "hi there" | werds - README.md stdin: 2 README.md: 124 total: 126

Or stdin can be used interactively with (with ^D to EOF):

$ werds - Hi there I just pased this in! ^D 7

The number of lines can also be counted instead of words with the -l (short for --lines) arg:

$ werds -l README.md 77

Install

cargo install --git git@github.com:brettchalupa/werds.git

Developing

Test Runner

Use cargo watch (cargo install cargo-watch) to run the tests when files are changed:

cargo watch -x check -x test
