# 
Gocovsh - Go Coverage in your terminal


`gocovsh` is a tool for exploring [Go Coverage

reports](https://go.dev/blog/cover) from the command line.

Don't skip the [Giving back](#giving-back) section! 💰

[Demo](#demo) below 🎬 👇

There is a Russian word *Ковш* (pronounced like "Kovsh") which means *a ladle*

or *a dipper*. ["The Big Dipper"](https://en.wikipedia.org/wiki/Big_Dipper) is

also a part of the constellation [Ursa

Major](https://en.wikipedia.org/wiki/Ursa_Major), thus the friendly

dipper-shaped Gopher mascot, created by [Michael Zolotov](https://www.mzolotov.com/).

## Installation

### Using [Homebrew](https://brew.sh/)

```bash

brew install orlangure/tap/gocovsh

```

### Pre-built binary

Grab your pre-built binary from the

[Releases](https://github.com/orlangure/gocovsh/releases) page.

### From source

```bash

# 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

1. Generate Go coverage report at your project's root with

    ```bash

    go test -cover -coverprofile coverage.out

    ```

   For more information about generating Go coverage reports, see 📝 [my blog

   post](https://fedorov.dev/posts/2020-06-27-golang-end-to-end-test-coverage/).

2. Run `gocovsh` at the same folder with `coverage.out` report and `go.mod`

   file (`go.mod` is required).

   ```bash

   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

   ```

3. 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](https://github.com/catppuccin/catppuccin) 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`:

```bash

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=` 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](https://tree-nation.com/plant/offer) 🌲 🌳 🌴

If you want me to know about your contribution, make sure to use

`[email protected]` as the recipient email.

Thank you!
