hasktags has some bugs, one of which is that it uses lazy IO, which tends to give those resource busy errors.
As it happens, I just wrote a tags program, at <http://hackage.haskell.org/package/fast-tags>
Other options are hothasktags, which makes qualified Module.function tags, and lushtags, which is de... | [

I think this is quite simple but after 2 days of trying I'm still clueless. Basically, I need to run one set of commands if the screen is over 767 pixels wide and another if the screen is under 767 pixels.
When the screen is wider than 767 pixels, I want to:

I am having a little bit of issues with some Undefined index. I realize this could be solved by changing it the error reporting using `error_reporting(E_ALL);`, or `ini_set('display_errors', '1');`, but would like to solve this without the need to change that. Right here is my block of code that throws the error.

Alternatively, another thing you can try is:
```
(gdb) p /x (char[6])*ptr
