Using Vim to generate HTML output of code

This is an interesting bit that I learnt about from an email in a mailing list by James Pryor.

To generate html output for code within a shell script you can use:

vim '+syntax on' '+ set nu' '+set background=light' +TOhtml '+w myscript.html' '+qall!'
If you don’t want numbers and need a dark background you can use:
vim '+syntax on' '+ set nonu' '+set background=dark' +TOhtml '+w myscript.html' '+qall!'

Installing EditorConfig on Sublime Text

To install Editor Config on Sublime Text all you need to do is to follow the following steps:-
  1. Go the Preferences tab -> Package Control.
  2. Select Install Package from the drop down menu.
  3. Wait for the list to load, once it loads it will show you a list of packages.
  4. Now, type in EditorConfig and select the highlighted option.

To confirm that Editor Config is installed correctly on your Sublime Text instance you can go to Preferences -> Browse Packages. If installed correctly you should be able to see an EditorConfig directory present in the Packages directory.

That’s it! Enjoy! 🙂

Installing Steam for Linux Beta | Counter Strike for Fedora 17 / 18 / 19 / 20

Here’s the link to a really interesting article by Russel Bryant that I found on the web. Especially helpful for all my geeky gamer friends who keep on complaining about how they are not able to play Counter Strike or Team Fortress 2 on their Linux based systems. Enjoy!

If however you are a counter strike freak and this link doesn’t completely satiate your needs, you may try referring to this blog for Chris Daniel’s take on installing Counter Strike on Fedora 18.

Debugging NO KEY warning during “yum install vlc”

This is a problem that I encountered today while tryiing to install VLC media player on my brand new Fedora 18 installation.

Right after the dependency resolutions are complete, yum returns the following warning:-

Transaction Summary
Install 1 Package (+45 Dependent packages)

Total size: 37 M
Installed size: 118 M
Is this ok [y/N]: y
Downloading Packages:
warning: /var/cache/yum/i386/18/rpmfusion-free/packages/live555-0-0.38.2012.10.18.fc18.i686.rpm: Header V3 RSA/SHA256 Signature, key ID 982e0a7c: NOKEY
Retrieving key from file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-18-i386

GPG key retrieval failed: [Errno 14] Could not open/read file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmfusion-free-fedora-18-i386

Did a bit of snooping around over the internet and found the missing rpmfusion keys at: and derived the following solution:-

Step by step solution to the problem [root login used]:-

  • I have already compiled the key into a single .gz file, which can be downloaded from this link:
  • Place the .gz file in the directory: /etc/pki/rpm-gpg/
  • #cd /etc/pki/rpm-gpg/
  • #tar -xvzf RPM-GPG-KEY-rpmfusion.tar.gz
  • rm RPM-GPG-KEY-rpmfusion.tar.gz
  • #yum install vlc
  • You should get this output after dependency resolution is complete:

    Is this ok [y/N]:

  • Enter ‘y’ (without the quotes!)

Voila! VLC’s installed!

NOTE:It is highly recommended to do a ‘yum update’ after the installation procedure is complete, as it helps ensuring that the new rpm keys are standards-compliant!
