Textmode

Recently drnic showed me his textmate bundle for github and I was really impressed.

It let’s you do the following:

• select some lines of code in Textmate, and open the same section (including selection hilighting) on the corresponding public github url

• go to a specific line of code, hit a key, and get directly to the github page of that commit and file, ready to post a comment

I didn’t even know about those possibilites github offers.. and I thought, wow I need this in my editor (vim) too.

So i created a little plugin, my first vim plugin, wrapping the – fortunately very modular – scripts drnic wrote.

There are 2 branches:

• Master – a standalone version without the github-tmbundle dependency
• TMB – a shorter version that depends on the scripts included in github-tmbundle

Both are available on my github repository as github-vim

The latter is easier to maintain since I only have to write calls to the existing methods, so I will update it with all new features in the tmbundle as soon as possible. But I will try to keep the standalone version as current as possible.

As mentioned this is my first vim plugin, therefore any suggestions, corrections and requests are very welcome.

Many things I did not really use or forgot. Check it out.

Ack-Grep is a replacement for grep written in perl.

It’s basic usage is ack fubar, which is about the same as grep -r fubar

It’s a very fast tool since it excludes a lot of files you don’t really want to search (like repository information, temporary files, backup files etc.) And furthermore it let’s you define and specify specific filetypes.

For example, I often want to search only .dryml files (I’ll mention in a future post what this is all about). To define such a custom simple define it in your ˜/ackrc like this:

--type-set=dryml=.dryml

This enables commands like

ack --dryml fubar

searching only files ending in .dryml

Furthermore the option ack-grep -f let’s you list the files only, without actually searching them, this can be useful, although good shells provide similar functionality. It’s nice to simply use something like

ack -f --dryml

You can even print the matching parts with perls special variables like $&.

Give it a try, you will like it! Note: The Debian package name is ack-grep, not ack.

I encountered the error “undefined method `size’ for false:FalseClass” with the ruby htmldoc gem

The error is caused by htmldoc (1.9svn here) returning some additional white spaces in it’s output and the htmldoc gem parser doesn’t recognize it. I was able to reproduce the bug partially when using images, but not always – which is quite funny ..

Anyways, a simple String#strip! helps, here is a patch for htmldoc.rb.

Edit:

To apply the patch download the file into the directory where htmldoc.rb is located (/var/lib/gems/1.8/gems/htmldoc-0.2.0/lib/ in my case), and run:

patch < htmldoc_gem_patch.txt

Yay, check out Opera Dragonfly, Opera’s answer to firebug.

Finally there is a good alternative to using the memory eating Firefox monster to get firebug’s functionality.

It’s only a Alpha release, without editing support, but I guess it’s in very good hands :)
