Removed intl/ entirely, and a few more tweaks by gettextize.
- i18nized a few strings used in DEBUG mode. (DLR)
- Some chars being assigned 0 are now assigned '\0'. (DLR)
- - Put header files in a more consistent order. (DLR)
+ - Put header file #includes in a more consistent order. (DLR)
- Remove some unneeded blank lines and spaces, and make some
spacing more consistent. (DLR)
- When possible, use iscntrl() to determine whether a character
is a control character or not. (DLR)
- Miscellaneous typo fixes. (DLR)
+ - Many fixes to the help browser and shortcut lists: efficiency
+ updates, consistency fixes, help text fixes and improvements,
+ and spacing improvements. (David Benbennick)
+ - Make more functions use const variables when possible. (David
+ Benbennick)
- files.c:
read_file(), read_line():
- Rework to properly handle nulls in the input file, fix
with it, instead of calling clear_filename() in two places.
Make startline an int instead of a long, since it's supposed to
hold a line number. (DLR)
+ - Properly handle multiple -r settings on the command line. (Carl
+ Drinkwater)
- search.c:
findnextstr():
- Update the current line at current_x if we don't find a match.
- (DLR)
+ Also, pass current_x_find to strstrwrapper() so we know whether
+ we're at the beginning of a string or not (see changes to
+ strstrwrapper() below), and reset it between lines. (DLR)
+ do_gotoline():
+ - Make sure placewewant is zero after we go to a line. (David
+ Benbennick)
do_gotopos():
- Simplify the sanity check to only put x within the range of the
current line; don't call actual_x() anymore. (DLR)
other than the terminating null in strings to newlines and
back; they're used to handle null characters in files properly.
(DLR)
+ strstrwrapper(): Set REG_NOTBOL when we're not at the beginning of a
+ string, to avoid false positives when searching for regular
+ expressions prefixed with ^. Make it take a new parameter,
+ line_pos, to determine where we are in the string. (DLR)
- winio.c:
actual_x_from_start():
- Overhaul to make cursor placement more like that of Pico: add
- After the user presses Enter at the prompt, refresh the edit
window in case there's a list of possible filename matches
(left over from attempted tab completion) on it. (DLR)
+ titlebar():
+ - Tweak text spacing and printing so that the titlebar text looks
+ better on smaller terminals. (Carl Drinkwater)
update_line():
- When marking control characters, make sure the mark moves
forward by two characters inctead of one. Rework control
