New or improved syntax files for the following languages:
The top Google help searches for JOE include:
How do I save and exit? The startup copyright notice has been replaced with basic help for beginners: ^K Q to exit and ^K H for help.
How do I dismiss the region highlighting? The traditional way is to hit ^K B ^K K, but this is slightly non-obvious and has always been awkward. Now Ctrl-C will do it.
How do I close all files and exit? Now Ctrl-K Q does this. Previously ^K Q was the same as ^C: abort a single file.
Restyle the help screens:
Make it more obvious that there is more than one screen: put the help for help inline with the text instead of in the (seemingly invisible) header.
Mention Ctrl-Arrow region selection, status and goto matching delimiter commands on the first screen.
Remove time and "Ctrl-K H for help" message from status bar. Beginners often don't notice this help message, and it takes up valuable status bar space that power users want for the context display.
Add ^KH for help to search and replace prompts. Many JOE users do not know about this context sensitive help.
Provide aborthint and helphint options so that the ^C and ^K H hints can be customized depending on the rc file (so say ^G for abort in jmacs, for example).
Enable -noxon by default (disable ^S/^Q flow control). This allows us to bind ^Q to quote and ^S / ^R to incremental search.
Document ESC X (command prompt) in the help screens.
"joe --help" now prints all command line options.
Tags search now tries to find the tags file in parent directories if it does not exist in the current directory and if the TAGS environment variable was not set.
Built-in calculator can now print and accept numbers in binary, octal and engineering formats: dec 12_345 eng 12.345_0e3 bin 0b11_0000_0011_1001 oct 0o3_0071 hex 0x3039
Built-in calculator now prints and accepts separating underscores for clarity. For example, 4_294_967_296 instead of 4294967296.
Enhanced calculator statistics functions:
Calculator region functions now assume the entire buffer if no region is set.
Tab completion now works at the calculator prompt (and in all prompts which allow numeric input, such as ^KL- go to line).
Make new regex engine (from JOE 4.1) more compatible with the classic engine. \y is now shorthand for \(\.\*\), so that it does what \* did in the old engine. Also:
Add -left and -right options to control the amount scrolling when the cursor moves past the left or right edge of the screen. When the baud rate is low these are automatically set to a large amount. Also, these now control the manual horizontal scrolling commands. When these are positive, they indicate number of columns. When they are negative, they indicate a fraction of the screen width (-2 is 1/2 the width).
Fix use after free bug which shows up as a crash in OpenBSD
Fix bug where indent step value was not shown on ^T menu
Fix bug where setting margin doesn't work on big-endian systems
Fix issue where highest valued unicode character equivalent was not translating to its corresponding 8-bit character. Effect of this was that Delete key was not working in shell windows in ASCII character set.
Standard deviation calculator function was not producing correct results.
Allow koi8r and koi8-r for KOI8-R in joe_getcodeset (which is only used if there is no setlocale).
Guess_crlf forced UNIX line endings for new files even though crlf was set. Now crlf is left alone if guess_crlf can not determine the line ending.
If cursor was at end of a long line and you switched to hex dump display mode, then hex dump was scrolled. Now scroll offset is reset when you switch to hex display mode.
