Joy of text is text editor, which includes a powerful ECCE-like scripting language for system tool integration and reusing any machine-readable input.
It recovers easily from crashes, can interface with helper and utility applications, provides many default library commands, macro-scriptability, debugging, includes spell checking, binary conversion routines (for office documents or pdf files), enables tabular text editing, and can deal well with larger file sizes.

Recent Releases
3.2.207 Feb 2025 03:00
major feature:
New features:
- All H path references now go via a new C function QueryPath() for more predictable
and consistent outcomes.
- Completely redefined the method of deleting hashtable entries, zombies are no more
but now there's defunct objects.
- Rewrite of AddNewFunctions, now completely general and also used by startup.jot
- Added protected windows.
- Fixed bugs affecting backtrace and failed-command messages, error reporting now
much clearer..
- Fixed bugs causing very slow screen updates in windows version.
- get.jot completely rewritten.
- Known bugs:
- Ctrl+C handling uses depricated non-posix functions - occasionally fails.
- Mouse-event coordinates are only accurate up to column 100 (xenial) or
about 200 (fedora xterm) - this is assumed to be a feature of the terminal emulators.
- In genuine windows-10, test_visual.jot fails any test involving reading back a unicode
character from the screen.
On visual inspection it seems to be displaying the characters correctly. The same tests all
pass in wine
so this one is assumed to be a bug in the windows-10 screen-readback function
ReadConsoleOutputCharacter( ).
The test_visual.jot script accepts the optional qualifier -win10relaxation to skip affected
tests.
- fake_emacs.jot, fake_vim.jot and fake_nano.jot are superficially OK but incomplete,
fake_emacs is particularly lacking functionallity.
