- Minor cosmetic tweaks to the ngettext() macro, and fix to - Minor cosmetic tweaks to the ngettext() macro, and fix to
properly detect systems lacking ngettext() and correctly properly detect systems lacking ngettext() and correctly
compile on them; the previous fix didn't work. (DLR) compile on them; the previous fix didn't work. (DLR)
- Fix problems with some code sections' not being #ifdef'ed out
when they should be, or being #ifdef'ed out improperly. (David
Benbennick and DLR)
- Change FOLLOW_SYMLINKS to NOFOLLOW_SYMLINKS, and rework the
associated logic accordingly, throughout the code. (David
Benbennick)
- Rework #ifdefs to not include mouse_init() at all if
DISABLE_MOUSE is defined or NCURSES_MOUSE_VERSION isn't. (DLR)
- For consistency, change many references of (!x) to (x == NULL)
and (x) to (x != NULL). (DLR)
- Define KEY_IC properly (and KEY_DC more portably) when slang
support is enabled, and remove the hack to work around the
former's not being defined. (David Benbennick and DLR)
- configure.ac: - configure.ac:
- Added tr to ALL_LINGUAS (Jordi). - Added tr to ALL_LINGUAS (Jordi).
- Fix now inaccurate description of --enable-tiny's effects; it
no longer disables NLS support. (DLR)
- Fix typo. (David Benbennick)
- Check for strcasecmp() and strncasecmp(), since they are
apparently only standard under BSD. (DLR)
- cut.c:
do_cut_text()
- Fix a memory corruption problem caused by accessing edittop
after it was freed but before it was reset to a sane value
from current. (David Benbennick)
do_uncut_text()
- If uncutting more than one line of unmarked text at editbot,
don't center the screen, since Pico doesn't. (DLR)
- files.c:
read_line()
- Miscellaneous cleanups. (David Benbennick)
read_file()
- Miscellaneous cleanups. (David Benbennick)
- Fix len's being off by one when reading in Mac-format files,
exposed by one of David Benbennick's cleanups. (DLR)
- If NO_CONVERT isn't set when we first enter, and it gets set
while reading in the file, unset it again afterwards. (DLR)
add_open_file()
- Fix minor logic error when determining when to resave fileage
and filebot. (DLR)
write_file()
- Change lineswritten from a long to an int, to match
filestruct->lineno. (DLR; mismatch found by David Benbennick)
input_tab()
- Variable name change: matchBuf -> matchbuf. (DLR)
diralphasort()
- Remove the HAVE_STRCASECMP #ifdef block; see the changes to
configure.ac and nano.h for why. (DLR)
- move.c:
do_page_down()
- If there's a page or less of text, do an edit_update() if the
mark is on; otherwise, the highlight won't be displayed. (DLR)
- nano.c: - nano.c:
do_prev_word()
- Make the assert match that in do_next_word(). (DLR)
do_enter()
- If smooth scrolling is on, and Enter is pressed on the
magicline, don't center the screen. (DLR)
do_justify()
- Fix memory corruption problem triggered when edittop and
current->next pointed to the same value and current->next was
destroyed during justification. (DLR)
- Center the screen when justification moves the cursor entirely
off the bottom of the screen, instead of when it moves the
cursor near the bottom of the screen, to more closely match
Pico's behavior. (DLR)
version() version()
- Remove obsolete reference to --enable-undo. (David Benbennick) - Remove obsolete reference to --enable-undo. (David Benbennick)
