pure.go 🐐

Exploring Golang by re-implementing pure prompt.

ℹ️ This is a really basic and naive implementation.

Preview

Installation

1. Download the release binary for your OS/Arch

2. Allow execution

   chmod u+x /path/to/pure

3. Try to execute manually

   $ /path/to/pure -version --last-command-status $status
   # should print something like:
   ~/projects/contributions/pure.go 🐐go1.20.3
   0 ❯

4. Edit your Fish, Zsh or Bash prompt (see below).

Configuring Shell Prompt

Fish

Edit $__fish_config_dir/functions/fish_prompt.fish with:

function fish_prompt
    /path/to/pure -version --last-command-status $status
end

Zsh

PROMPT=$(/path/to/pure -version --last-command-status $status)

Bash

export PS1='$(/path/to/pure -version --last-command-status $status)'

Development

Usage

❯ go run ./cmd/cli.go -version --last-command-status $status

or with the built binary

❯ make build
❯ ./pure --last-command-status $status
# or
❯ make demo

Install

❯ make install

Test

❯ make test

Build

Create a pure binary in the project's root directory.

❯ make build
❯ ./pure --last-command-status $status

Todo

• create a pure package
  • add pure package to go.mod
  • add pure package to go.sum
• print prompt ❯ with pure package
• test pure package output (with testify)
• create a CLI (with clîr)
• add current working directory to prompt
• add go version to prompt when go.sum exists
• configure Goreleaser
• add color to output
