Ogl

The prettiest git log graph in town!

Why

We all love the terminal. git log --graph is cool, but it can get really hard to read.

Installation

The easiest way is to get the single binary (available in releases page).

Install with a single command:

On Linux

$ sudo curl -sL https://github.com/onilton/ogl/releases/download/v0.0.2/ogl-linux.tar | tar x -C /usr/local/bin/

Or with wget:

$ sudo wget -qO- https://github.com/onilton/ogl/releases/download/v0.0.2/ogl-linux.tar | tar x -C /usr/local/bin/

On MacOS

$ curl -sL https://github.com/onilton/ogl/releases/download/v0.0.2/ogl-macos.tar | tar x -C /usr/local/bin/

Or with wget:

$ wget -qO- https://github.com/onilton/ogl/releases/download/v0.0.2/ogl-macos.tar | tar x -C /usr/local/bin/

Access to usr/bin is restricted after Catalina 2019. A semi-secure work around is to create a new bin folder (in home directory for example) and link to PATH: *Feel free to use wget instead of curl *Add export path line to .bashrc for OS X or .zshrc for perminant usage

$ mkdir ~/bin
$ export PATH="${HOME}/bin:${PATH}" 
$ curl -sL https://github.com/onilton/ogl/releases/download/v0.0.2/ogl-macos.tar | tar x -C ~/bin/
$ chmod -R go-w ${HOME}/bin

Config file

You can change some settings like colors in ~/.ogl. An example config:

####################                                                                                                                                                     
#Example Config
#################### 

# Seed is used to get a random color. We usually use the color from
# git log --graph itself but sometimes a color isn't provided so
# we need to choose a random color
#seed=3

# The graph/line style: "squared" "dual" "heavy" "default" (or "rounded")
style=rounded

# This fixes some column sizes. 
#unlimited-fields=false 
#subject.width=60
#author.width=15
#date.width=15

# Field colors
#subject.color=15
#author.color=66
#date.color=237

# Hide consecutive date and author
#hide-consecutive=true

# Align commit messages
#align-messages=false

# Number of columns to give up aligning commits
# When graph is too wide it can get hard to read commits
# even in pieces where it is not that wide yet
#max-align-messages=70

# Enable unicode icons for branch/ref names
#unicode-icons=true

# Personalize branch/ref icons
#icon.origin="🐱  "
#icon.tag="⚑ "
#icon.local="⌨  "
#icon.head="✓"

# Customize commit bullet 
#icon.commit.bullet="◦"
#icon.commit.childless="◦"

TO-DO

• This was made as proof of concept, so the code needs a lot of love to become prettier
• More customizations
• Use other libs when they become available to scala-native
• Tests!!
• Packaging?
• It is fast. But if possible, make it (even) faster
• ~~Not tested in Mac OS X yet. #4~~ Thanks @justinpitts !

Questions

• Why scala? - Because I like it! :) To be honest I started with a prototype in python, but after facing some performance issues, and trying a little bit with cython, I decided to try scala-native.
• Wow, that scala code is ugly! - Unfortunately, idiomatic scala code is not that fast, and I tried to do that best possible to keep the time down. If you know how to improve the code without affecting performance, send a PR! :)
