The earliest memory I have of ‘programming’ is in the early/mid 90s when my father brought home a computer from work. We could play games on it … so of course I took the spreadsheet program he used (LOTUS 123, did I date myself with that?) and tried to modify it to print out a helpful message for him. It … halfway worked? At least I could undo it so he could get back to work…

After that, I picked up programming for real in QBASIC (I still have a few of those programs lying around), got my own (junky) Linux desktop from my cousin, tried to learn VBasic (without a Windows machine), and eventually made it to high school… In college, I studied computer science and mathematics, mostly programming in Java/.NET, although with a bit of everything in the mix. A few of my oldest programming posts on this blog are from that time.

After that, on to grad school! Originally, I was going to study computational linguistics, but that fell through. Then programming languages (the school’s specialty). And finally I ended up studying censorship and computer security. That’s about where I am today!

But really, I still have a habit of doing a little bit of everything. Whatever seems interesting at the time!

Wombat IDE - Two bug fixes

2012-06-09

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

2012-05-25

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

2012-05-20

Additional features:

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.
Made links in the about dialog clickable.
Issue 186: Fixed the recent document manager on documents with the same name.

Wombat IDE - Vector of vector functions

2012-05-03

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

2012-04-30

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:

Wombat IDE - Help and image bug fixes

2012-04-29

A new feature: any keyword can now have an associated hyperlink that points to the Chez Scheme API reference for that function. Just click on a function that you want help with and hit F1 on your keyboard. The link will open in your systems default browser. So far only the functions built into Petite Chez Scheme work correctly, I’ll be adding the C211 libraries as soon as I write the documentation for it.

Wombat IDE - Another round of issues

2012-04-19

I have a new chunk of issues this time, this time with screen shots.

Updated turtle library with new names

Essentially, I’ve changed a few of the names in the previous turtle API and added a few new alias.

spawn has been renamed to hatch
split has been been renamed to clone
teleport! has been added as an alias to move-to!
turn-counter-clockwise! has been added as an alias to turn-left!
turn-clockwise! and turn! have been added as aliases to turn-right!

Wombat IDE - Animated turtles

2012-04-13

Sometimes I keep going beyond the point where I probably should. In this case, I want to add an animation feature to the turtle graphics library so I just went ahead and wrote one.

These new functions have been added to the turtle API:

(live-display b) - b should be #t or #f to enable or disable the live display, default is #f
(live-delay n) - set the timer between frames, default is 0.1 seconds
(live-display) - is live display enabled?
(live-delay) - get the current delay

Wombat IDE - Turtle graphics

2012-04-13

As I mentioned in my last post, I’ve been adding a turtle graphics library to Wombat to use with the other C211 libraries (matrix, image, and tree).

Wombat IDE - A pile of features and bugs

2012-04-12

Another one of those posts. 😄 Bug fixes: Fixed a problem with the interop libraries reporting they were finished before they actually were. Now when reading a few hundred images, the call will block until they are actually read rather than just pretending to read them as it was. Issue 158: Prevent backups of backup files (no double ~). Basically, if a person directly edits a backup file, they’re on their own.
