CVS code -
- General:
+ - Miscellaneous comment fixes. (DLR)
+ - More int -> bool conversions. (DLR)
- Add the ability to scroll up or down single lines without
scrolling the cursor, via Meta-- and Meta-+. Note that this
is disabled when NANO_SMALL is defined. New functions
(DLR)
- nano.h:
- Readd MIN_EDITOR_COLS #define, set to 4. (DLR)
+- proto.h:
+ - Remove now-unused externs for currslen, shortcut_list,
+ fileinfo, syntaxfile_regexp, and synfilematches. (DLR)
- prompt.c:
do_statusbar_input()
- Fix misplaced break when handling NANO_VERBATIM_KEY. (DLR)
do_rcfile()
- Remove unneeded assert. (DLR)
- search.c:
+ search_abort()
+ - Rename to search_replace_abort(). (DLR)
findnextstr()
- Remove parameter can_display_wrap, as it's always set to TRUE
now, and rename parameter wholeword to whole_word, for
consistency. (DLR)
- Only include the whole_word parameter when DISABLE_SPELLER
isn't defined, as it's only used then. (DLR)
+ replace_abort()
+ - Replace with search_replace_abort(), since it does the same
+ things that this function does. (DLR)
do_replace_loop()
- Change order of parameters to more closely match those of
findnextstr(), and rename parameter wholewords to whole_word,
- Fix test so that we scroll through the line in 8-character
chunks when COLS is greater than 8, not when COLS is greater
than 9. (DLR)
+ remove_magicline()
+ - Add assert. (DLR)
- winio.c:
nanoget_repaint()
- Rename parameter inputbuf to buf, for consistency. (DLR)
