execute_command(), remove execute_command(), remove
resize_variables(), rename get_buffer() get_key_buffer(), and
rename get_buffer_len() get_key_buffer_len(). (DLR)
- Replace all mvwaddstr(hblank) calls with a new function that
does the same thing without the need for hblank. New function
blank_line(); changes to do_browser(), blank_titlebar(),
@ -31,6 +32,19 @@ CVS code -
- Make the static pid variable used by execute_command() and
cancel_command() a pid_t instead of an int, for consistency.
(DLR)
- Consistently make the flags global and any variables used to
hold it longs. (DLR)
- Consistently make the fg and bg colortype struct entries and
any variables used to hold them shorts. Changes to
do_colorinit() (renamed color_init()), color_to_int() (renamed
color_to_short()), and parse_colors(). (DLR)
- Change color handling to save only the regex strings
constantly, and to actually compile them on an as-needed
basis. Also, don't bother doing complete refreshes of the
screen when color support is enabled if there's no regex
associated with the current file. Changes to update_color()
(renamed color_update()), thanks_for_all_the_fish(),
do_input(), and do_output(), (DLR)
- files.c:
open_file()
- Assert that filename isn't NULL, and don't do anything special
@ -64,13 +78,13 @@ CVS code -
allow_pending_sigwinch()
- Simplify by using the "?" operator instead of an if clause.
(DLR)
main()
- When constant cursor position display is on, only display the
cursor position if there are no keys waiting in the buffer.
(DLR)
- nano.h:
- Since we only use vsnprintf() now, remove the #ifdef block for
HAVE_SNPRINTF. (DLR)
- rcfile.c:
nregcomp()
- Return TRUE when the compilation succeeds and FALSE otherwise,
instead of the other way around. (DLR)
- search.c:
search_init()
- Don't blank out last_replace anymore when we get a new string,
