Demo below 🎬 👇

There is a Russian word Ковш (pronounced like "Kovsh") which means a ladle or a dipper. "The Big Dipper" is also a part of the constellation Ursa Major, thus the friendly dipper-shaped Gopher mascot, created by Michael Zolotov.

Installation

Using Homebrew

brew install orlangure/tap/gocovsh

Pre-built binary

Grab your pre-built binary from the Releases page.

From source

# install latest, probably unreleased version
go install github.com/orlangure/gocovsh@latest

# or install a specific version
go install github.com/orlangure/[email protected]

Usage

Generate Go coverage report at your project's root with
```
go test -cover -coverprofile coverage.out
```
For more information about generating Go coverage reports, see 📝 my blog post.

Run gocovsh at the same folder with coverage.out report and go.mod file (go.mod is required).

gocovsh                        # show all files from coverage report
git diff --name-only | gocovsh # only show changed files
git diff | gocovsh             # show coverage on top of current diff
gocovsh --profile profile.out  # for other coverage profile names

Use j/k/enter/esc keys to explore the report. See built-in help for more key-bindings.

Themes

gocovsh supports 4 nice themes (using Catppuccin Theme project) and an ugly default one at this moment. To change the theme, set GOCOVSH_THEME environment variable to one of the following values: mocha, latte, frappe or macchiato:

GOCOVSH_THEME=mocha gocovsh
GOCOVSH_THEME=latte gocovsh
GOCOVSH_THEME=frappe gocovsh
GOCOVSH_THEME=macchiato gocovsh

To always use the same theme, add export GOCOVSH_THEME=<theme name> to your ~/.bashrc, ~/.zshrc or any other file that you use for shell configuration.

Giving back

This is a free and open source project that hopefully helps its users, at least a little. Even though I don't need donations to support it, I understand that there are people that wish to give back anyway. If you are one of them, I encourage you to plant some trees with Tree Nation 🌲 🌳 🌴
