|
||||
CVS code -
|
||||
- General:
|
||||
- Translation updates (see po/ChangeLog for details).
|
||||
- Change uncast nrealloc()s assigned to char pointers/arrays to
|
||||
charealloc()s, and cast all other nrealloc()s and all
|
||||
nmalloc()s. (David Benbennick and DLR)
|
||||
- utils.c:
|
||||
align()
|
||||
- Tweak to avoid a potential problem when strp is non-NULL but
|
||||
*strp is NULL. (David Benbennick)
|
||||
- winio.c:
|
||||
nanogetstr()
|
||||
- Fix problem with search history where a temporary string
|
||||
added at the bottom of the history (but which was not in the
|
||||
history) would not be preserved after scrolling down to the
|
||||
blank bottom entry and then scrolling back up. (DLR)
|
||||
- configure.ac:
|
||||
- Change the program used to detect a broken regexec() function
|
||||
so that it works properly, using information found at
|
||||
http://sources.redhat.com/ml/libc-hacker/2001-06/msg00015.html.
|
||||
(DLR)
|
||||
- nanorc.sample:
|
||||
- Revised comment explaining the non-escaping of quotes to cover
|
||||
non-escaping of all shell-interpreted characters. (DLR)
|
||||
- Fixes to the descriptions and examples in the comments, and
|
||||
changes to some default values. (David Benbennick and DLR)
|
||||
- Add regexes for Perl syntax. (Richard Smith, tweaked for
|
||||
greater efficiency by David Benbennick)
|
||||
- Add regexes for Java source syntax. (David Benbennick)
|
||||
Regex for C++-style comments (colored the same way as C-style
|
||||
comments) added by DLR.
|
||||
- THANKS:
|
||||
- Added Laurentiu Buzdugan, for Romanian.
|
||||
- Added Geir Helland, for Norwegian Bokmål.
|
||||
- TODO:
|
||||
- Move the items for nano 1.2 to the "Old Requests" section,
|
||||
and mark color syntax highlighting as done. (David Benbennick)
|
||||
- nano.1, nanorc.5:
|
||||
- Formatting improvements by Jean-Philippe Guérard.

- Search (etc.) string history [DONE]

- Implement Pico's -j and -g flags, as they are pretty easy to do. [DONE]

keystroke to ungetch(). [DONE].

left (allows resizing that way), formerly -W arg. [DONE]
|
