CVS code -
- General:
- Translation updates (see po/ChangeLog for details).
- Updated nano.1, nano.1.html, and nano.texi to fix an
inaccuracy in the description of -Q/--quotestr. (DLR)
- Set REG_EXTENDED in all regcomp() calls. (DLR)
- Minor cosmetic code cleanups. (DLR)
- configure.ac:
- Added pt_BR to ALL_LINGUAS (Jordi).
- files.c:
open_file()
- String change: "File "x" is a directory" -> ""x" is a
directory". (Jordi)
open_prevfile_void(), open_nextfile_void()
- Return the return values of open_prevfile() and
open_nextfile(), respectively, instead of (incorrectly)
calling them and returning 0. (DLR)
real_dir_from_tilde()
- Rework to use getpwent() exclusively and end reliance on
$HOME. Adapted from equivalent code in do_rcfile(). (DLR)
@ -11,6 +22,18 @@ CVS code -
- Most likely fixed the check marked with FIXME, so that tab
completion works properly when we're trying to tab-complete a
username and the string already contains data. (DLR)
- move.c:
page_up()
- Fix bug where current is moved up two lines when the up arrow
is pressed on the top line of the edit window; this causes a
segfault is the top line in the edit window is the second
line of the file, as the line current ends up on doesn't
exist. (Jeff Defouw)
do_down()
- Fix bug where, if the last line in the edit window is the
line before the magicline, and smooth scrolling is turned
off, pressing the down arrow on that last line centers the
cursor without updating the edit window. (Jeff DeFouw)
- nano.c:
do_next_word(), do_prev_word()
- If we're on the last/first line of the file, don't center the
@ -24,6 +47,25 @@ CVS code -
- Rework to only call edit_refresh() unconditionally if
ENABLE_COLOR is defined; if it isn't, and we're not deleting
the end of the line, only call update_line(). (DLR)
do_wrap()
- Make sure wrapping is done properly when the number of
characters on the line is exactly one over the limit. (David
Benbennick)
do_alt_speller()
- Readd DLR's fix to preserve marking when using the alternate
spell checker; it was accidentally dropped. (David
Benbennick)
do_justify()
- Fix cosmetic problems caused when justifying on the
magicline. (David Benbennick)
- nano.h:
- Change search toggles for case sensitive searching and regexp
searching to M-C and M-R, respectively. (DLR; suggested by
Chris)
- TODO:
- Add entry in the 1.4 section for Pico's paragraph searching
ability (at the search prompt, ^W goes to the paragraph's
beginning, and ^O goes to the paragraph's end). (DLR)
