Changes
- General:
- - Completely removed PICO_MODE, as with the search/replace history
- patch we should have the extended functionality we can without
- being incompatible with pico. Removed all code for different
- search/replace string editing and alternate shortcut list. I'm sure
- I won't even have to ask for feedback on this one :-)
- - Add in Pico's -p flag, (-p, --preserve). To preserve the XON and XOFF
- keys (^Q and ^S). Add warning if we invoke -p and add checks for
- using --preserve (to skip warning) and --pico (to force showing it).
- New flag PRESERVE, function do_preserve_msg(), changes to main(),
- signal_init().
- - Search history and replace history up/down cursor arrows, w/history
- tab completion, not available w/NANO_SMALL. Changes to
- statusq, others (Ken Tyler). Added shortcut to search/replace
- shortcuts so people will know it's there, forced KEY_UP and KEY_DOWN
- defs in nano.h (Chris, in case blame needs to be placed later).

+ and ^N as alternatives to the up and down arrows, make sure
+ the "Up" shortcut is displayed properly in the help menu,
+ remove a few bits of unneeded and/or warning-generating code,
+ and fix some missing statusq() prompts with --enable-tiny.
- Translation updates (see po/ChangeLog for details).
- Forward-ported Chris' --disable-wrapping-as-root option from
1.0.9. Per Jordi's suggestions, have it override
- Define KEY_IC properly (and KEY_DC more portably) when slang
support is enabled, and remove the hack to work around the
former's not being defined. (David Benbennick and DLR)
+ - Miscellaneous tweaks to update_color() calls, to make sure
+ they're called at the right times and that refreshes are done
+ afterwards only when needed. (David Benbennick)
+ - Renamed [have_]past_editbuff [have_]search_offscreen. (DLR)
+ - Add the "preserve" option to the nanorc file, to match
+ nanorc.sample. (DLR)
- configure.ac:
- Added tr to ALL_LINGUAS (Jordi).
- Fix now inaccurate description of --enable-tiny's effects; it
- Fix typo. (David Benbennick)
- Check for strcasecmp() and strncasecmp(), since they are
apparently only standard under BSD. (DLR)
+- color.c:
+ update_color():
+ - Remove an unneeded edit_refresh() call after do_colorinit().
+ (David Benbennick)
- cut.c:
do_cut_text()
- Fix a memory corruption problem caused by accessing edittop
- If uncutting more than one line of unmarked text at editbot,
don't center the screen, since Pico doesn't. (DLR)
- files.c:
+ load_file()
+ - Remove unneeded wmove() call. (David Benbennick)
read_line()
- Miscellaneous cleanups. (David Benbennick)
+ open_file()
+ - If we're in multibuffer mode and there's an error opening the
+ file in read-only mode, display the error message on the
+ statusbar regardless of the value of quiet. (DLR)
read_file()
- Miscellaneous cleanups. (David Benbennick)
- Fix len's being off by one when reading in Mac-format files,
exposed by one of David Benbennick's cleanups. (DLR)
- If NO_CONVERT isn't set when we first enter, and it gets set
while reading in the file, unset it again afterwards. (DLR)
+ do_insertfile()
+ - If we're in multibuffer mode and there's an error opening the
+ file that we're trying to insert, close the new buffer that we
+ made to hold it and reload the buffer we had open before.
+ (DLR)
add_open_file()
- Fix minor logic error when determining when to resave fileage
and filebot. (DLR)
+ load_open_file()
+ - If switching between files when CONSTUPDATE is set, only force
+ a cursor position display update if DISABLE_CURPOS isn't set.
+ This will ensure that the "Switching to [file]" messages are
+ shown. (DLR)
write_file()
- Change lineswritten from a long to an int, to match
filestruct->lineno. (DLR; mismatch found by David Benbennick)
+ real_dir_from_tilde()
+ - Since this is needed for proper interpretation of paths
+ containing tildes and not just for tab completion, include and
+ use it regardless of whether tab completion is disabled.
+ (David Benbennick and DLR)
input_tab()
- Variable name change: matchBuf -> matchbuf. (DLR)
diralphasort()
- Remove the HAVE_STRCASECMP #ifdef block; see the changes to
configure.ac and nano.h for why. (DLR)
+- global.c:
+ thanks_for_all_the_fish()
+ - Miscellaneous cleanups. (David Benbennick)
- move.c:
do_page_down()
- If there's a page or less of text, do an edit_update() if the
mark is on; otherwise, the highlight won't be displayed. (DLR)
- nano.c:
- - Added free_history list calls clean up, added init of list headers
- modified statusq calls (Ken Tyler).
+ - Added free_history() list calls clean up, added init of list
+ headers, and modified statusq() calls (Ken Tyler).
do_prev_word()
- Make the assert match that in do_next_word(). (DLR)
do_enter()
more useful feedback to the user when spell checking fails.
ABCD()
- Renamed abcd(). (DLR)
+ main()
+ - Remove an unneeded do_colorinit() call, do major cleanups, and
+ allow loading of multiple files on the command line when
+ multibuffers are used. (David Benbennick)
- nano.h:
- Make sure NO_RCFILE and COLOR_SYNTAX aren't set to the same
value. (DLR; discovered by Ken Tyler)
- If strcasecmp() and/or strncasecmp() aren't available, use
- strcmp() and/or strncmp instead. (DLR)
+ strcmp() and/or strncmp() instead. (DLR)
+- proto.h:
+ - Fix the #ifdef block for DISABLE_TABCOMP's being undefined
+ so that functions only used with tab completion are properly
+ #ifdef'ed out. (DLR)
+- search.c:
+ print_replaced()
+ - Remove and replace with an equivalent ngettext() call. (DLR)
+ do_replace_loop()
+ - Fix bug where if text on the magicline was replaced (which can
+ be done via a regexp replace of "^$" with something other than
+ ""), a new magicline wouldn't be created. (DLR)
+ do_replace()
+ - For greater Pico compatibility, when an attempt to replace a
+ string results in 0 replacements due to the string's not being
+ found, display "[string] not found" instead of "Replaced 0
+ occurrences". (DLR)
- utils.c:
+ align()
+ - Don't just assert that the string passed in isn't NULL; check
+ that it isn't and only do the alignment when it isn't. (David
+ Benbennick)
+ nmalloc(), nrealloc()
+ - If the size passed to nmalloc() or nrealloc() is zero, don't
+ die with an erroneous out-of-memory error. Also, change
+ their dying messages to "nano is out of memory!". (David
+ Benbennick)
+ charalloc()
+ - Removed and redefined as a macro that calls nmalloc(). (David
+ Benbennick)
is_cntrl_char()
- Rework to fix a problem with displaying certain high-bit
characters. (David Benbennick; reported by Andrzej Marecki)
- Added double hash marks to comment lines, so people who
uncomment the beginning of every line won't get syntax errors.
- faq.html:
- - Miscellaneous fixes and updates for typos and broken links.
- It is now fully compliant with HTML 4.01 Transitional. (DLR)

<h2><a name="1.4"></a>1.4. What is the history behind nano?</h2>
<blockquote><p>Funny you should ask!</p>
<p><b>In the beginning...</b></p>
<p>For years Pine was THE program used to read email on a Unix system. The Pico text editor is the portion of the program one would use to compose his or her mail messages. Many beginners to Unix flocked to Pico and Pine because of their well organized, easy to use interfaces. With the proliferation of GNU/Linux in the mid to late 90's, many University students became intimately familiar with the strengths (and weaknesses) of Pine and Pico.</p>
<p><b>Then came Debian...</b></p>
- <p>The <a href="http://www.debian.org">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but they were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>

/">Debian GNU/Linux</a> distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but they were not truly free software in the <a href="http://www.gnu.org/philosophy/free-sw.html">GNU</a> sense of the word.</p>
<p><b>The event...</b></p>
<p>It was in late 1999 when Chris Allegretta (our hero) was yet again complaining to himself about the less-than-perfect license Pico was distributed under, the 1000 makefiles that came with it and how just a few small improvements could make it the Best Editor in the World (TM). Having been a convert from Slackware to Debian, he missed having a simple binary package that included Pine and Pico, and had grown tired of downloading them himself.</p>
<p>Finally something snapped inside and Chris coded and hacked like a madman for many hours straight one weekend to make a (barely usable) Pico clone, at the time called TIP (Tip Isn't Pico). The program could not be invoked without a filename, could not save files, had no help menu, spell checker, and so forth. But over time it improved, and with the help of a few great coders it matured to the (hopefully) stable state it is today.</p>

<blockquote><p>The U of W license for Pine and Pico is not considered truly Free Software according to both the Free Software Foundation and the <a href="http://www.debian.org/social_contract#guidelines">Debian Free Software Guidelines</a>.
