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.

Wombat IDE - A new way

2012-04-11

Up until now, the Petite bindings have been built around a threaded model where one thread existed solely to send new commands to the Petite process and another solely to read responses back. Mostly, this would stop the problem with the Java Process model that would cause it to deadlock if the data was not actually being consumed–the reading thread could act as a buffer in this instance.

Wombat IDE - Busy day for small changes

2012-03-27

Bug fixes:

Issue 138: Automatically create a backup file (with a ~ suffix) on save and an option to disable it. There have been a few issues with Wombat crashing that I haven’t managed to track down, this should help people recover from those. (They’re rare; as in 2 cases reported among over 150 students for several months, so this shouldn’t happen to the majority of users).
The mnemonic in the recent documents menu has been tweaked to be ascending and 1 based rather than descending and 0 based.
Fixed an issue where occasionally hitting enter in the REPL wouldn’t run the current code based on incorrect bracket matching.
list->image and image->list are not properly highlighted as keywords.

Wombat IDE - A helping hand and image library updates

2012-03-22

Two interesting things to talk about this update. First, I have my first code contribution from someone else. I’ve been working with Graham during Peer Tutoring for C212 and when we were busy, we talked about Wombat. He seemed interesting in helping, so he worked out the new about dialog for Wombat. Now it has all of the different libraries and licenses that Wombat uses, along with a nice picture.

Many thanks! (And if anyone else wants to contribute, feel free. It’s always nice to get a different viewpoint on things.)

Wombat IDE - Assorted bug fixes (λ‎ mode fixed)

2012-03-09

A few minor bug fixes first:

Fixed the cursor jumping to the end of the document on saves. This was being caused by the code that automatically trimmed whitespace, which will still change the file on disk but won’t change the actual open document.
Apparently, there were some lingering issues with the undo/redo stack sometimes erasing the document. If this happens, you can always undo once more to get passed it, but I think I’ve tracked down why it was happening. If it happens again, please let me know.
Fixed an error where closing documents through the InfoNode close event wouldn’t actually remove them from memory.

Wombat IDE - Updated draw-image

2012-02-29

After a long while, I’ve actually done some work on the frame displayed with draw-image. Now rather than just showing the basic image, there’s a bit of extra information available.

Wombat IDE - 64 bit Petite

2012-02-27

64-bit Linux and OSX machines will now download a 64-bit version of Petite rather than the previous 32-bit versions that I was downloading for all of the systems. This should mostly help to alleviate problems that some people were having with installing the necessary 32-bit libraries on their systems. Unfortunately, this requires an update to the actual launcher, so anyone that needs the new features will need a new build of the launcher.
