Git: display current branch name in the terminal

enter image description here
As simple as beautiful trick for me.
Add following lines to ~/.bashrc to allow your terminal to display the current branch name in the command line :

get_git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}

PS1="[\u@\h \W\[\033[31m\]\$(get_git_branch)\[\033[00m\]]$ "

Gedit: make links clickable (with Ruby script)

Image
Gedit is my favorite text editor in Ubuntu . It’s almost perfect for me. I use it for fast files editing or simple scripts writing when I don’t want to open my IDE . But I feel uncomfortable with Gedit when I cannot click links directly in text. We can fix it easily with External Tools plugin. All we need is to write a simple script (I prefer Ruby ) and run it through External Tools . Write Ruby script Create click_link.rb in your home directory. Paste following text to click_link.rb #!/usr/local/bin/ruby v1 = ARGV [ 0 ] require "uri" url = URI . extract ( v1 )[ 0 ] system ( "firefox #{url.to_s}" ) Do not forget to make click_link.rb executable chmod + x click_link . rb Create External Tool for Gedit Enable External Tools plugin in Preferences Tools > Manage External Tools Add new tool Paste following text #!/bin/sh /< your_path_to_file >/ click_link . rb $GEDIT_CURRENT_LINE Set Input = Current line and se...

Using Jenkins as HTTP server for your custom HTML

Image
Jenkins CI has its own small HTTP server after installation. You can use it easily when you need to publish your own html pages, e.g. code documentation such as Rdocs or YARD docs.

Now you can find your pages on http://<your_jenkins_url>/userContent/your_page.html . As a result you’ve got http -server with restricted access for Jenkins users. Written with StackEdit .
