Gap.app 0.61

The new 0.6 version of Gap.app comes with an improved and streamlined interface. It supports the latest releases of GAP. The Gap.app+GAP edition comes with GAP 4.11 built in -- install everything you need by downloading and dragging Gap.app to your Applications folder!

Some advantages of Gap.app

• Display graphical XGAP windows. Interactively examine the subgroup lattice structure of a group. It's easy to expand this support to examine other partially ordered sets.
• Save what you're doing with File | Save (or with the standard ⌘-S shortcut). Gap.app saves graphical display windows, too!
• No extra steps are required to install GAP -- it comes built-in to the Gap.app+GAP edition.
• Easily load the .g file that you're working on with ⇧⌘-O. Reload the last file with ⌥⇧⌘-O!
• Mac-centric user interface

New in 0.61

• Better compatibility with Mojave, including dark mode
• Other stability and polish fixes

New features in 0.6

• Search command history in a Mac-like way with ⇧-↑ (Shift-Up Arrow)
• Install the 'gap' shell command for use from Terminal.app from a menu item (requires a built-in copy of GAP)
• Many improvements to the command window, making the interface more fluid:
  • reverse (dark) mode
  • improved command completion popup positioning
  • Allow Ctrl-D to exit break loop, but not to accidentally quit GAP
  • Option-Shift-Command-O rereads last Shift-Command-O file
  • bounce Gap.app icon when a >10sec computation finishes in background
• Several low-level improvements to GAP support
  • gap> prompt is handled better
  • readline support is included in the built-in GAP
  • Gap.app will warn if running external GAP when built-in GAP is available
