@ -5,20 +5,26 @@ CVS code -
the translation of files from DOS or Mac format (DLR).
- New functions wheck_writable_directory() and safe_tempnam()
to get around the tempnam warning. More improvements (DLR)
Still eeds testing.
Still needs testing.
- Added DOS and Mac format options to write file routine.
Changes to shortcut_init() and do_writeout().
- Removed stupid static definitions of toggles and shortcut
lists. Many changes to shortcut_init(), toggle_init(),
statusq(), nanogetstr(), main(), and many other places.
FIXME: Mouse support broken by this change.
- Multibuffer mode now allows multiple empty filenames.
Changes to add_open_files(), removed open_file_dup_search(),
open_file_dup_fix(), etc (DLR).
- New code to handle multiple .save files. Changes to
die_save_file(), new function files.c:get_next_filename()
and utils.c:num_of_digits(). (Dwayne Rightler, DLR & Chris)
- Makefile.am:
- Add SYSCONFDIR to DEFS, so we can have an /etc/nanorc.
- Change localedir line to 1.0's version.
- files.c:
read_byte()
- Added check for conrol characters (indicative of a binary
file), set NO_CONVERT if found.

- global.c:
- Move openprev and opennext functions to shortcuts, they really
aren't toggles (DLR).
