Gap.app / News: Recent posts

Gap.app 0.7a fixes a bug with loading a saved session. Gap.app 0.7 would give an error message and enter a GAP break loop on loading. Sessions saved in 0.7 are loadable in 0.7a, subject to the usual caveats about GAP saved workspaces.

Gap.app v0.7 has an all-new in-app browser for GAP help, along with many other improvements and fixes. The Gap.app+GAP edition includes GAP 4.12.1.

Main new features include:

GAP built-in to Gap.app+GAP is universal: supports M1 as well as Intel
The version of GAP built-in to Gap.app+GAP is now 4.12.1, and includes the normalizinterface and cddinterface packages
Browse GAP help in the new built-in help viewer

Fit Poset Width to Window button added on XGAP poset sheets
Zooming and sizing of sheets is much more sensible in general

Call Reread instead of Read on Option-Command-Shift O
Restyle Memory Usage panel to be smaller; hide details by default
Better support for touchbar
Improved handling of carriage return and backspace in GAP command window

Gap.app v0.61 is a stability and polish release. The Gapdotapp+GAP edition includes GAP 4.11.0.

Main new features include:
Better compatibility with Mojave/Catalina, including support for dark mode
Other stability and polish fixes

Between the Gap.app bug fixes and the new GAP release, I recommend that all users upgrade to this version.

Gap.app v0.6 has a number of improvements, especially to the command window. The Gapdotapp+GAP edition includes GAP 4.10.0.

Main new features include:

Browse and search command history with Shift-↑
Improvements to GAP command completion appearance
Reverse (light on dark) mode for GAP command window
Many new preferences for command window appearance
Holding down Option while choosing Read File Into Workspace will reread last file chosen
Gap.app now starts GAP in the user's home directory

GAP will by default warn if Gap.app is using an external copy when built-in is available
"gap --gui" will start Gap.app from a terminal window (requires patch to GAP)
Automated installation via menu item of GAP shell command in Gap.app+GAP
The version of GAP included with Gap.app+GAP is now 4.10.0, and includes the nq package

Significantly improved and polished. Main new features:

Works with recent versions of GAP

Fixes a crash on launching external executables, notably help; improvements to terminal emulation.

Version 0.2 would crash if it didn't find GAP in /usr/local/lib -- this has been fixed. Preferences were added for (not) loading .gaprc and for loading a saved workspace.

CocoaGap 0.2 now supports command-line completion, either via the Tab key (as in GAP), or via ESC or F5 (as in OS X).

There are also some minor bug fixes, and a number of lower level changes, including use of a pseudo terminal to communicate with GAP.

An update with minor (mostly cosmetic) bug fixes.

CocoaGap is a native Macintosh OS X GUI for the GAP computer algebra system. It is designed to replace xgap without requiring X11.

This initial release has most of the functionality of xgap. It allows the display and inspection of subgroup lattices, just like xgap. A few things (such as command completion) are missing. As in any initial release, there may be bugs, although these should not affect the result of computations.
