mark-yank-urls: fix bug allowing shell to interpret the url

[ link: 20090530223801 | tags: urxvt shell desktop | updated: Fri, 15 Jan 2010 22:27:56 ]

I committed a fix for an annoying bug in the urxvt mark-yank-urls script.

This has been reported by several people. I have finally fixed it, but the credit should go to Hans Dieter Pearcey, Daniel Danner and Olof Johansson for reporting it.

wmiirc-lua v0.2.8 release

[ link: wmiirc-lua-v0.2.8 | tags: lua wmii desktop wmiirc-lua | updated: Fri, 15 Jan 2010 22:27:56 ]

I've packaged up the recent changes made to wmiirc-lua and released a new version.

This release is mostly about bug fixes, and moving things around. Particularly, I've moved the project to github, and also the new configuration files live in ~/.wmii-lua not ~/.wmii-3.5 (which clearly didn't make sense).

There are many fixes to the packaging and startup scripts to make things more robust. I've also revisited and fixed building Debian packages (at least for Debian/Lenny).

If you've used the kitchen sink repository you should note that this repository is being deprecated in favour of storing the wmii and libixp repositories as submodules of wmii-lua -- so no need for a container repo like the kitchen sink.

wmiirc-lua moving to github

[ link: wmiirc-lua-github | tags: lua wmii desktop wmiirc-lua | updated: Fri, 15 Jan 2010 22:27:56 ]

I had as surge of new interest in wmii-lua in the last couple of months. I thought it would be good to officially state here that I've been moving the wmii-lua git repositories to github.

android true type font

[ link: ttf-droid | tags: font desktop linux debian | updated: Fri, 15 Jan 2010 22:27:56 ]

Following a random tweet on identi.ca I upgraded my proprotional fonts on Debian/Sqeeze to ttf-droid.

I expect that some day this font will be packaged by Debian, but for now I had to:

    wget 'http://launchpadlibrarian.net/21202254/ttf-droid_1.00%7Eb112%2Bdfsg-0ubuntu1_all.deb'
    sudo dpkg -i ttf-droid_1.00\~b112+dfsg-0ubuntu1_all.deb

Because I am a big console junkie I don't use proprtional fonts much, but they do look nice on the web.

wmiirc-lua v0.2.5 release

[ link: wmiirc-lua-v0.2.5 | tags: lua wmii desktop wmiirc-lua | updated: Fri, 15 Jan 2010 22:27:56 ]

A kind wmiirc-lua user, Sytse Wielinga (sytse on irc), had debugged an old issue in luaixp code I had written for wmiirc-lua.

While this bug directly addresses raw mode (Mod4-space), I belive that this will fix a bunch of weird issues so I released v0.2.5. Since v0.2.4 there was also a small bug in the battery plugin that was fixed.

I packaged up the latest modules and bug fixes of wmiirc-lua and made a v0.2.4 release.

four steps to reproducible Debian installs

[ link: private-essential-debs | tags: debian desktop apt dpkg | updated: Fri, 15 Jan 2010 22:27:55 ]

For ever now some friends and I have been talking about making essential packages, which would pull in all the tools that we often use on Debian. So here goes...

With the power of the equivs package, this is actually a very short procedure.

wmiirc-lua kitchen sink repository

[ link: wmiirc-lua-kitchen-sink | tags: lua wmii desktop wmiirc-lua | updated: Fri, 15 Jan 2010 22:27:55 ]

wmiirc-lua is a replacement for sh-based wmiirc that ships with the wmii window manager.

I have had some issues with the libixp and wmii packages under Debian. Particularly the problem is caused by the fact that libixp (and wmii use of the library) changes often but do not have any way to detect subtle changes in the API from the sources.

I decided to track everything in a kitchen sink repository that will include all the sources that need to be versioned and released together. That way what you try is the same thing I tried. Currently this includes

  • libixp imported from mercurial
  • wmii imported from mercurial
  • wmiirc-lua

This of course uses magic git powers; or more specifically git submodules. To follow along you will need git 1.5.3 or newer.

wmiirc-lua v0.2.1 remembers a bit more

[ link: wmiirc-lua-v0.2.1 | tags: lua wmii desktop wmiirc-lua | updated: Fri, 15 Jan 2010 22:27:55 ]

wmiirc-lua is a replacement for sh-based wmiirc that ships with the wmii window manager.

In version 0.2.1 wmii will remember the last few programs that have been ran and the last few actions taken. It will put those entries at the beginning of the completion list. Frequent items can thus be selected with arrow keys and pushing enter.

In this release selecting works spaces with Mod4-[a-z] will not select the first view that starts with that letter, but rather the most recently used view that starts with the letter.

There have also been a few bug fixes, notably the core will now look in ~/.wmii-3.5 for plugins and core libraries before looking in system directories. That will solve the problem of someone using make install-user while having an older .deb installed.
