Powerline, git, Fedora

 | February 12, 2016 2:31 pm

I recently discovered powerline, thanks to a Fedora news article. Getting powerline running on your Bash terminal is completely trivial and discussed in the article. You just:

Install powerline.

  sudo dnf install powerline

Configure your shell to use the powerline daemon.

bash

Add this to your .bashrc

  if [ -f `which powerline-daemon` ]; then
     powerline-daemon -q
     POWERLINE_BASH_CONTINUATION=1
     POWERLINE_BASH_SELECT=1
     . /usr/share/powerline/bash/powerline.sh
  fi

fish

add this to ~/.config/fish/config.fish:

set fish_function_path $fish_function_path "/usr/share/powerline/fish"
powerline-setup

Configure powerline to display git information

If all you want to do is get the git branch displayed on your powerline, that’s pretty easy, see for example this excellent article. But after I discovered powerline-gitstatus, I just had to have it.

Install the powerline-gitstatus segment:

pip install powerline-gitstatus

Setup a configuration

I’ve put my powerline configuration up on github, so if you like, you can start with my configuration, and play with it from there simply by clone my powerline-configuration repository into your local .config directory. I.e.:

cd ~/.config
git clone https://github.com/spacemoose/powerline_cofiguration.git powerline

Otherwise you can copy over the default configuration and follow the directions here.

Try out your new configuration

Since this article is focused on customizing our shell prompt, we are dealing with the powerline daemon, which means we must run

powerline-daemon --replace

when we want to see what effect our changes might have – BUT before you do that, I highly recommend running powerline-lint in case you forgot a comma somewhere.

Org2Blog

 | February 3, 2016 12:08 am

Aah, good news. There’s a plugin that lets me post to my wordpress blog using Emacs org mode. The github repository is here. The mainpage documentation creates an unecessarily complicated picture of what has to be done to get this puppy running. On emacs 24.5.1 all I had to do was:

  • installed org2blog using emacs package manager.
  • install the following two lines to my .emacs:
(setq org2blog/wp-blog-alist
      '(("a-name"
         :url "http://username.your-blog-address.net/xmlrpc.php"
         :username "your-username"
         :default-title "Hello World"
         :default-categories ("org2blog" "emacs")
         :tags-as-categories nil)
		))
login with
M-x org2blog/wp-login.
post to drafts
M-x org2blog/wp-post-buffer

And hey presto, I’m up and running. I can write my posts in a first class editing evironment, using a first class markup language, and just export it with a keystroke (there are default keybindings, but I’m not using them yet). More’s possible, but for the moment I’m satisfied with that. For example, there are instructions on the github page explaining how to create a post template, and how customize your authentication, but so far I haven’t felt the need.

Now, let’s see if this leads to more posts on my part.
