- Fix minor bugs with importing certain text files in Mac
format. (DLR)
- files.c:
+ append_slash_if_dir(), input_tab()
+ - Changed variable names: lastWasTab -> lastwastab, matchBuf ->
+ matchbuf. (DLR)
+ check_operating_dir()
+ - Memory leak fix. (David Benbennick)
+ check_writable_directory()
+ - Optimizations (David Benbennick).
+ cwd_tab_completion()
+ - Changed a variable name: dirName -> dirname. (DLR)
+ do_browser()
+ - Optimizations and mouse selection fixes (David Benbennick).
+ do_writeout()
+ - Fix problem with formatstr's being defined as NULL when
+ --enable-tiny is used. Since formatstr isn't ever used in tiny
+ mode, don't bother even creating the variable. (David
+ Benbennick and DLR)
+ do_insertfile()
+ - Memory leak fix (accidentally dropped 1st time).
+ (David Benbennick).
+ get_full_path()
+ - Memory leak fix. Also, make it properly interpret ~/ notation
+ so, among other things, the option "--operatingdir ~" works.
+ (David Benbennick)
+ - More optimizations (David Benbennick).
new_file()
- Make sure current_x is zero; this fixes a problem where the
current cursor position wasn't reset when reading in a file in
multibuffer mode. (David Benbennick)
+ - Use make_new_node rather than setting up fileage by hand
+ (David Benbennick).
read_file(), read_line()
- Rework to properly handle nulls in the input file, fix
detection of binary files to properly mark a file as binary if
writing a marked selection to a file, save and restore totsize
so it isn't decreased by the size of the selection afterward.

- global.c:
free_toggles()
- Only include if we're not using tiny mode. (David Benbennick)
- nanorc.sample:
- Put in much less crappy example regex rules for c-file.
- nano.c:
- do_char()
- - Fix a problem where, if ENABLE_COLOR wasn't used, typing
- characters on a marked line before the beginning of the mark
- would make the highlight short by one. (David Benbennick)
+ clear_filename()
+ - Remove this function, as it has unneeded functionality, is
+ short enough to be inlined, and is only called in two spots
+ anyway. (DLR)
die()
- Rework slightly to remove redundant printing of last message
and print all messages after resetting the terminal. (DLR)
- global_init()
- - Call die_too_small() when fill is 0. (DLR)
- usage()
- - List the options that are ignored for the purpose of Pico
- compatibility, and make some minor consistency fixes. (DLR)
- do_next_word(), do_prev_word()
- - Fix a problem where highlighting isn't done properly after
- calling either of these, and another problem where the cursor
- would move back too far in certain cases with do_prev_word().
- (David Benbennick)
do_backspace()
- Make sure placewewant is set properly, and that the mark is
moved backwards. (David Benbennick)
+ do_char()
+ - Fix a problem where, if ENABLE_COLOR wasn't used, typing
+ characters on a marked line before the beginning of the mark
+ would make the highlight short by one. (David Benbennick)
+ do_cont()
+ - Handle the case where the window was resized while we were
+ stopped. (David Benbennick)
do_delete()
- Make sure placewewant is set properly, to match Pico's
behavior. (DLR)
- clear_filename()
- - Remove this function, as it has unneeded functionality, is
- short enough to be inlined, and is only called in two spots
- anyway. (DLR)
do_int_spell(), do_alt_spell()
- Rework to save the marked selection before doing spell checking
and restore it afterward. (DLR)
- do_cont()
- - Handle the case where the window was resized while we were
- stopped. (David Benbennick)
+ do_next_word(), do_prev_word()
+ - Fix a problem where highlighting isn't done properly after
+ calling either of these, and another problem where the cursor
+ would move back too far in certain cases with do_prev_word().
+ (David Benbennick)
+ do_toggle()
+ - Since the search mode toggles aren't global anymore, we don't
+ need to explicitly block them here anymore (which will end up
+ blocking the global backup mode toggle, which is the same as
+ the backwards search toggle). (DLR)
+ do_wrap()
+ - fill fixes and 'two short word wrap' bug (David Benbennick).
+ global_init()
+ - Call die_too_small() when fill is 0. (DLR)
handle_sigwinch()
- Make sure we adjust fill when the window is resized. (David
Benbennick)
help_init()
- Since the return value of snprintf() isn't well defined, use
sprintf() instead. (David Benbennick)
- do_toggle()
- - Since the search mode toggles aren't global anymore, we don't
- need to explicitly block them here anymore (which will end up
- blocking the global backup mode toggle, which is the same as
- the backwards search toggle). (DLR)
main()
- Rework to blank out filename manually before doing anything
with it, instead of calling clear_filename() in two places.
can be treated separately from -r/-T string. (DLR)
- Fix so that Esc-Esc-Space is properly treated as Ctrl-Space.
(DLR)
+ usage()
+ - List the options that are ignored for the purpose of Pico
+ compatibility, and make some minor consistency fixes. (DLR)

- Fix some space/tab formatting for flags (DLR).
