# Wombat IDE - New semester / bug fixes

We’re about to start up the Fall semester, so it seems like a good time to be updating Wombat for the new semester. With that, a whole slew of bugs have been squashed:

# Wombat IDE - It's Alive! (bug fixes)

It’s alive!

I haven’t worked on Wombat in a while, but with the new semester quickly approaching, I figured that it would be a good time to take out a few of the outstanding bugs on the issue tracker. Granted, there’s still a fair few, but it’s a start.

# Wombat IDE - The return of screen sharing

I’ve been working the last few days to get screen sharing working again and I think I have something. Again. Hopefully. The first idea was to use a UDP multicast network but when router configuration on campus got in the way, I moved back to a more direct TCP-based system. Still, I think it works pretty well.

# Wombat IDE - Two bug fixes

Two quick bug fixes:

• Issue 196: color-set! now works correctly (previously it wouldn’t actually mutate the color object)
• Issue 197: Automatically determine the correct semester for the upload button

# Wombat IDE - OSX Dock Icon

For the longest time, I’ve been having issues with the Dock Icon on OSX. It isn’t set using the same code that works in Windows and Linux, but I think I’ve finally figured it out.

Using information from this blog post, I can use the com.apple.eawt.Application class to set the Dock Icon. It isn’t set immediately on launch, but shortly thereafter. Not perfect, but close.

# Wombat IDE - Another bug fix / feature post

• Since both the image and turtle libraries need the same color code, I’ve factored that out into it’s own module: [(c211 color)](http://www.cs.indiana.edu/cgi-pub/c211/wombat/docs/c211-color.htm "C211 Color API")
• Issue 193: Opening a file on top of an empty replaces that document.

Bug fixes:

• Fixed documentation issues with image->list, list->image,
• Issue 187: Fixed the direction parameter to hatch to take degrees rather than radians to match the rest of the library.
• Issue 186: Fixed the recent document manager on documents with the same name.

# Wombat IDE - Vector of vector functions

Added two functions to the matrix library:

• (vov->matrix vov) - converts a vector of vectors to a matrix
• (matrix->vov m) - converts a matrix to a vector of vectors

Quick and simple, but highly useful for testing and display purposes.

# Wombat IDE - Updated syntax, documentation

First, a few bug fixes with the keyword lists and help links: Added a bit of code to differentiate between a normal let and a named let. Fixed for losing the syntax definitions on some systems. Also, I wrote code to generate help files for the C211 libraries. Theoretically, I should just be able to update these with future updates to the APIs: Image API Matrix API Tree API Turtle API Color API (Edit: Added 19 May after re-factoring of colors) As a side note, I’ve added two new functions to the tree API:
