tc-setup-v0.20.exe
August 10, 2011
  • Removed: memory view ghosting, wasn’t being used
  • Removed: unused menustrip items
  • Fixed: Titlebar text was overwriting close and collapse buttons
  • Fixed: Closing the build/output/search panes would result in the form itself closing, rather than just hiding
  • Fixed: It was possible to drag memory views completely off screen and lose them. Now they snap back if dragged off screen.
  • Fixed: Unintialized/dead pointers were receiving highlighting, which made it look like they actually pointed at something

  • Fixed: “Save project as” was annihilating the project
  • Fixed: Clicking on “Add existing item” over the headers folder would pop up a dialog that defaulted to .c extensions. Now it defaults to .h.
  • Fixed: Was crashing when there were no editor windows open and you attempted to click on the editor region
  • Fixed: When last field of a struct was an array, the indentation line didn’t close.
  • Fixed: Build/output panes were not being cleared when project closed.

  • Fixed: Find dialog did not have keyboard focus when it came up

July 28, 2011

  • Greatly improved: Support for large arrays.
  • Improved: Ignacio’s stack meter. Added gradient and ability to zoom in on specifics like stack address and esp.
  • Improved: Settings dialogs. Gave all dialogs a standardized look.
  • Improved: Changed context color for #include statements. Previously, it was the same color as comments, which was confusing.
  • Fixed: Realloc was not working.

tc-setup-v0.15.exe
June 9, 2011
  • Feature: Editor themes
  • Feature: Tab indentation settings (finally!)
  • Fixed: Current line indicator was overwriting line number
  • Fixed: Highlighted pointers were retaining their highlights when source memory view was closed using the drop down menu
tc-setup-v0.14.exe
May 30, 2011
  • Added: Tabbed “Locals” and “Everything” views
  • Added: Font selection to settings
  • Feature: Console window pops to foreground when keyboard input is required (scanf, getch, etc.)

  • Improved: printf, putc, etc. hooks. Now will update the “Output” pane in real time.
tc-setup-v0.13.exe
May 23, 2011
  • Added: Ability to flip between “Locals” and “Everything”
  • Added: Callstack dropdown menu that isolates single functions (locals + parameters)
  • Added: A variety of icons indicating if a variable is an uninitialized pointer, an active pointer, a pointer target, or a regular ol’ var

  • Fixed: whenever a function was hidden, the stack mark remained, although it was connected to nothing
tc-setup-v0.11.exe
May 4, 2011
  • Added: Copy-To-Clipboard functionality for build output
  • Modified: Visual indicator for dead/uninitialized pointers. Got rid of the red X, replaced it with an “alert” symbol (exclamation point inside a triangle)
  • Fixed: A dynamically-casted array of structures was not displaying properly if the backing store was too small to cover a single struct.
  • Fixed: interleaving malloc’s and free’s confused the display, causing it to remove the incorrect memory view when a deallocation occurred.
  • Fixed: When a pointer source was hidden (i.e., buried inside a collapsed array/struct) there was no visual indication that it was pointing to anything. Now, when that happens, a dashed pointer arrow emanates from the head of the array.
  • Fixed: Scrolling over a closed array was causing it to open.
  • Fixed: Casting between int * px and int ** ppx was producing the same dynamic memory view.
