Configuring powerline to show working Git branch

So the documentation for Powerline kind of sucks. I followed this pretty good article on getting started with it. First thing I noticed however is that the if statement on the article doesn’t work if you don’t have powerline installed (which kind of defeats the purpose of having the if statement there at all).

# if powerline is installed, then use it
command -v powerline-daemon &>/dev/null
if [ $? -eq 0 ]; then
powerline-daemon -q
POWERLINE_BASH_CONTINUATION=1
POWERLINE_BASH_SELECT=1
. /usr/share/powerline/bash/powerline.sh
fi

Next up is the configuration. I primarily use my bash prompt as a way to indicate which branch I’m working in within a Git repository. You need to point at the default_leftonly theme which is pretty easy to find when you web search for it. The issue is everything seems to just point you at the powerline docs, which aren’t the most clear.

First, start by creating a local configuration directory that will override the configuration for powerline for your user.

$ mkdir -p ~/.config/powerline

Then the next thing is to copy over the config.json from the main powerline configuration directory where you can find the available color schemes and other shell, i3, vim, etc themes.

(Again, the documentation kind of sucks on where the root of these configurations live…)

On my Fedora 22 system they live in /etc/xdg/powerline/. I then copy the config.json from that directory to ~/.config/powerline

To get the Git branch stuff going, I modified the configuration file in the following way:

--- /etc/xdg/powerline/config.json 2015-02-18 18:56:51.000000000 -0500
+++ /home/lmadsen/.config/powerline/config.json 2015-09-09 17:11:43.937522571 -0400

},
"shell": {
"colorscheme": "default",
- "theme": "default",
+ "theme": "default_leftonly",
"local_themes": {
"continuation": "continuation",
"select": "select"

To make it active you can run powerline-config --reload. If you have any errors in your configuration (I actually ran into this when playing with the colorscheme setting and used “solorized” instead of “solarized”), you can check it with powerline-lint.

Brother printer doesn’t print in Fedora 17

Tip: If your Brother printer won’t print after installing the drivers, install glibc.i686

Today ran into an issue with my new Brother MFC-7460DN (which is a really nice laser printer with auto-feed scanner, Scan-to-FTP which creates a PDF file, and other things). I had just recently done a clean install of Fedora 17, and I could install the RPMs (which are i386 files on my x86_64 based system), add the printer to CUPS and all sorts of things that looked fine.

However when I went to print, it wouldn’t error out, but the printer wouldn’t actually print. I tried changing a file per https://bbs.archlinux.org/viewtopic.php?pid=940524#p940524 but it didn’t help.

Then I found this post http://forums.fedoraforum.org/showthread.php?t=280753 which reminded me to install glibc.i686. Wish the Brother drives would just make that a dependency in the RPM.
