The latest version is now 1.0.13: please wait until that appears in the ftp
directory before getting joe.
Version 1.0.13 includes fixes for these bugs:
- A long sequence of searches or a search & replace with a lot of
replacements would cause the editor to exit and display an 'Out of memory'
message.
- If you deleted characters on a long line on a terminal which has a delete
character command, spaces would someimtes be shifted in place of some of
the characters.
- If you hit SPACE BACKSPACE RETURN on an otherwise empty prompt line, the
editor would hang.
- If you typeahead a bunch of returns as the editor is starting, they would
be converted to ^Js by the tty, which is the kill-line function in joe.
- When a backup file is created, any existing file of the same name is first
deleted. This fixes a problem when joe is being used for ELM- other
people's backup files in the /tmp directory would prevent you from saving
your own file. This is also useful when root edits a file in some user's
account. The user wouldn't then be able to save his file because joe
couldn't write to root-owned backup file.
Also these improvements to the search & replace system were made:
The wildcard \* now will not cross line boundaries. This ends up being more
useful.
\+ now tries to make the longest possible match, instead of the shortest.
This is much more intuitive:
\[A-Za-z_]\+\[A-Za-z0-9_] is all that's needed to match C
identifiers. It used to be:
\[A-Za-z_]\+[A-Za-z0-9_]\[^A-Za-z0-9_]
\* still makes the shortest possible match though. \c (like \*- but don't
stop in balanced expressions) should be used in 99% of all cases you needed
\* to make a longed match.
A full set of backslash escape sequnces is now available for search:
\a, \n, \r, \b, \t, \e, \f
match ascii: BEL, LF, CR, BS, TAB, ESC, FF.
\377 Octal
\xFF Hex
Can be used to match a character with specific ASCII code given in
octal or hex.
The escape sequences can be used inside of \[...] as well.
