|
- Whitespace display (M-P) does not require configuration to be useful.

|
- Emergency savefiles retain ownerships and permissions when possible.
|

|
|
|
|
Visible changes since 1.2
|
|
-------------------------
|
|
* Editor Features
|
|
- Support for UTF-8.

|
|
- Insertion of spaces instead of a tab when Tab is pressed (-E).
|
|
- The long option for -K is now --rebindkeypad.
|
|
- Regular expression searching can now be toggled when nano is built
|
|
with --enable-tiny, so -R now means something else (see below).
|
|
- Restricted mode that provides more security than -o (-R).
|
|
- Blanking of the statusbar after 1 keystroke instead of 25 (-U).
|
|
- Word searches can optionally skip over punctuation (-W).
|
|
- Workaround for Delete's acting like Backspace (-d).
|
|
- Many more options are supported in the nanorc.
|
|
- Improvements to color syntax highlighting support: case insensitive
|
|
matching, the ability to include color syntaxes in separate files,
|
|
the ability to specify background colors without foreground colors,
|
|
etc.
|
|
- Insertion of single-byte characters via Esc Esc <000-255>.
|
|
- Insertion of all characters via "Verbatim Input" mode.

|
|
Meta-L.

|
- Indenting lines with one keystroke.
|
|
- Copying text into the cutbuffer without cutting it.

cursor.

|
|

|
|
- Going to the first or last line of the current paragraph.
|
|
- Going to the first or last line of the file without having to go to
|
|
the "Search" prompt.
|
|
- Searching for filenames in the file browser.
|
|
- Displaying spaces and tabs differently to make it easier to tell
|
|
them apart.
|
|
- Many more functions available at the statusbar prompt: moving to the
|
|
next or previous word, searching for matching brackets, "Verbatim
|
|
Input" mode, etc.
|
|
- The glibc 2.2.3 crashes involving extended regular expressions are
|
|
no longer worked around, as they can break anything using extended
|
|
regular expressions, and glibc 2.2.3 is old. You should upgrade to
|
|
at least glibc 2.2.4.
|
|
|
|
* File Handling
|
|
- Automatic adding of newlines to the ends of files without them can
|
|
now be disabled (-L).
|
|
- Converting from and to DOS/Mac file format is now toggled only at
|
|
the "Write File" prompt, via Meta-D and Meta-M, and the default file
|
|
format to save in is now set depending on what format the file was
|
|
originally in. -D now makes nano use bold text instead of reverse
|
|
video text, and Meta-D at the edit window now does a
|
|
word/line/character count. -O now makes the unused second line of
|
|
the screen part of the edit window, and Meta-O at the edit window
|
|
now toggles this behavior.
|
|
- Converting files that contain a mix of DOS and Mac format lines.
|
|
- Automatic switching on of -N with binary files has been removed, as
|
|
it causes problems with UTF-8 support.
