nano/ChangeLog.2007-2015

[Development moved to git on April 1.  The Changelog was discontinued.]


2016-03-31  Benno Schulenberg  <bensberg@justemail.net>
	* src/text.c (do_int_spell_fix): Replace a fake 'while', delete a
	redundant 'if', rename a variable, and adjust whitespace.

2016-03-30  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (do_replace_loop, go_looking, findnextstr): Report
	"Cancelled" instead of "Not found" when the user aborts a replace
	that is taking too long.  This fixes Savannah bug #47439.
	* src/winio.c (do_replace_highlight): Rename this to 'spotlight',
	for clarity, and for contrast with 'do_replace/do_replace_loop'.
	* src/winio.c (spotlight): Rename a variable for clarity.
	* src/files.c (input_tab), src/prompt.c (get_prompt_string):
	Rename a variable to better indicate booleanness.
	* src/text.c (do_int_speller): Unwrap a few lines.

2016-03-29  Benno Schulenberg  <bensberg@justemail.net>
	* src/nano.c (main), src/text.c (do_justify, do_verbatim_input),
	src/winio.c (parse_escape_sequence): Place the cursor in the edit
	window also when --constantshow is in effect, after a ^J Justify or
	an invalid escape sequence, and when entering a verbatim keystroke.
	Leave the cursor off during Unicode input, for extra feedback.
	* src/browser.c (do_browser): Improve the wording of a message.
	* src/chars.c (is_valid_unicode): Speed up Unicode validation.
	* src/text.c (do_int_spell_fix): Allow to stop replacing a word
	without aborting the entire spell-fixing session.
	* src/search.c (do_replace_loop): Chop a now-unused parameter.

2016-03-28  Benno Schulenberg  <bensberg@justemail.net>
	* src/winio.c (statusbar): Don't bother putting back the cursor in
	the edit window, as it is off anyway, and will be placed back in the
	main loop.  This prevents a segfault when trying to open a directory.
	* src/search.c (findnextstr): Provide feedback when searching takes
	longer than roughly half a second (on average).
	* src/*.c: Remove the 'last_replace' variable that is never used.
	* src/winio.c (parse_kbinput): Delete a no-op.

2016-03-23  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (findnextstr): Prevent the internal spell checker from
	finding the first occurrence twice.  And delete the piece of dead code
	that was meant to do this.  This fixes Savannah bug #47188.
	* src/search.c (findnextstr): Clean up and rename a variable.
	* src/search.c (findnextstr): Poll the keyboard once per second.
	* src/winio.c (reset_cursor): Remove a pointless condition, and make
	use of an existing intermediary variable.
	* src/winio.c (reset_cursor): Tidy up and rename a variable.
	* src/winio.c (onekey): Elide an unneeded 'if' and unneeded variable.

2016-03-22  Thomas Rosenau  <thomasr@fantasymail.de>
	* configure.ac, src/*.c: Check for the existence of the REG_ENHANCED
	regex flag, and use it when it's available (on OS X systems).  This
	completes the fix for Savannah bug #47325.

2016-03-21  Benno Schulenberg  <bensberg@justemail.net>
	* src/browser.c (findnextfile): Trim a duplicate variable.
	* src/browser.c (browser_refresh, findnextfile): Rename four vars.

2016-03-20  Benno Schulenberg  <bensberg@justemail.net>
	* src/files.c (do_writeout), src/nano.c (do_exit): Normalize the
	punctuation in some prompts: no space before a question mark, and
	a semicolon instead of a comma between phrases.
	* src/text.c (do_cutword): Don't put cut words into the cutbuffer --
	that is: treat the deletion of words like pressing Backspace/Delete.
	* src/search.c (get_history_completion, find_history): Cycle through
	the items from newest to oldest.  This fixes Savannah bug #47205.
	* src/files.c (do_writeout): When the name of the file was changed,
	always ask whether this is okay.  This fixes Savannah bug #46894.
	* src/search.c (do_research): Use 'return' instead of 'else'.
	* src/search.c (do_search): Don't bother setting 'answer'; just	use
	'last_search', which has been set to 'answer' in search_init().
	* src/search.c (go_looking): Factor out the common part of
	do_search() and do_research() into this new function.

2016-03-19  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (search_init): Always remember the last typed string,
	also when it's an invalid regex.  This fixes Savannah bug #47440.
	* src/search.c (search_init, do_replace): Don't bother setting the
	current answer to the empty string, as do_prompt() can handle a NULL.
	* src/browser.c (do_browser): Delete a snippet of dead code.
	* src/browser.c (do_browser): Delete an unneeded variable.
	* src/search.c (do_gotolinecolumn): Delete another unneeded variable.
	* src/search.c (search_init): Snip an always-FALSE condition.
	* src/search.c (search_init): Reshuffle stuff to reduce indentation.
	* src/search.c (do_replace): Snip a useless setting of answer.

2016-03-17  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (do_research): Use the Search key bindings also during
	a Re-search, to enable cancelling.  This fixes Savannah bug #47159.
	* src/search.c (do_replace): Remove two redundant returns.
	* src/search.c (findnextstr): Prune two #ifdefs.
	* src/search.c: Adjust some indentation.

	* src/rcfile.c (parse_colors): Make error message equal to others.
	* src/rcfile.c (parse_rcfile): Rearrange some things to reduce the
	indentation level by four steps, so we can unwrap a dozen lines.

2016-03-13  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (regexp_init): Allow using the word boundary markers
	\< and \> in search strings on non-GNU systems.  This is a partial
	fix for Savannah bug #47325 reported by Thomas Rosenau.
	* src/rcfile.c (parse_rcfile, parse_colors, nregcomp): Combine the
	regular-expression flags at compile time instead of at run time.
	* src/rcfile.c (parse_syntax, parse_colors): Rename a variable.
	* src/winio.c (edit_draw): Give a central variable a ringing name.

2016-03-13  Thomas Rosenau  <thomasr@fantasymail.de>  (tiny change)
	* autogen.sh, README.SVN: Mention SVN instead of CVS.

2016-03-12  Benno Schulenberg  <bensberg@justemail.net>
	* src/color.c (color_update): Set the syntax and regex pointers
	just once, in a single place.  And unnest two 'if's.
	* src/rcfile.c (parse_one_include, parse_includes): New names for
	these functions, to be more distinguishable.
	* src/rcfile.c (parse_colors): Reduce the indentation.
	* src/rcfile.c (parse_colors): Rename a variable.
	* src/rcfile.c (parse_colors, parse_rcfile): Refind the tail of

2016-03-11  Benno Schulenberg  <bensberg@justemail.net>
	* src/browser.c (do_browser): Fix compilation when configured with
	--enable-tiny plus --enable-browser.
	* src/rcfile.c: Tweak some comments and reshuffle some lines.
	* src/rcfile.c (color_to_short): Elide a variable.
	* src/rcfile.c (grab_and_store): First check that there is an
	open syntax before checking that it is named "default".
	* src/rcfile.c (parse_rcfile): Fix compilation when configured with
	--enable-tiny plus --enable-nanorc.

2016-03-10  Benno Schulenberg  <bensberg@justemail.net>
	* src/rcfile.c (grab_and_store): Do not accept 'header' and 'magic'
	commands for the default syntax.  This fixes Savannah bug #47323.
	* src/rcfile.c (pick_up_name): Fold the parsing of a linter and
	formatter command into a single routine.
	* src/rcfile.c (parse_header_exp, parse_magic_exp, grab_and_store):
	Elide the first two functions, and reshuffle parameters in the last.
	* src/rcfile.c (parse_syntax, parse_rcfile), src/color.c
	(color_update): Turn the linked list of syntaxes upside-down, so that
	the last-defined one comes first, so that searching can stop at the
	first match instead of always having to run through the entire list.
	* src/rcfile.c: Rename a variable to better fit its new role.

2016-03-09  Benno Schulenberg  <bensberg@justemail.net>
	* src/rcfile.c (parse_syntax): Produce an adequate error message
	when the syntax name is unquoted.  This fixes Savannah bug #47324.
	* src/rcfile.c (parse_syntax): Use the grab_and_store() function
	also for gathering up extension regexes.

2016-03-04  Benno Schulenberg  <bensberg@justemail.net>
	* src/color.c (found_in_list): Don't bother keeping the compiled
	regular expression when it matched -- drop this tiny optimization
	for when opening multiple files.  Instead stop calling malloc().
	* src/nano.h: Delete a now-unused struct member.
	* src/global.c (free_list_item): Elide this now too tiny function.
	* scr/global.c (thanks_for_all_the_fish): Rename three variables.
	* src/rcfile.c (parse_colors): Tweak a few things.
	* src/color.c (color_update): Rename a variable.

2016-03-01  Benno Schulenberg  <bensberg@justemail.net>
	* src/rcfile.c (parse_syntax), src/color.c (color_update): Don't
	bother discarding a duplicate syntax (it's too rare, saves little
	memory, and freeing it properly	would cost even more code), just
	select the last-defined one.  This addresses Savannah bug #47303.
	* src/color.c (color_update): Allow to select an empty syntax.

2016-02-29  Benno Schulenberg  <bensberg@justemail.net>
	* src/nano.h, src/rcfile.c, src/color.c: Rename a struct member.
	* src/rcfile.c (parse_rcfile): Don't allocate a struct for the
	"none" syntax (and thus prevent it from being extended).

	* src/rcfile.c (parse_rcfile): Close an extended syntax again.
	* src/rcfile.c (parse_rcfile): Rename a variable.
	* src/rcfile.c (grab_and_store): Fix breakage of r5695.
	* src/color.c (color_update): Do not dereference symlinks, so that
	the syntax will be derived from the name given on the command line,
	not from that of the target file.  This fixes Savannah bug #47307.

2016-02-28  Benno Schulenberg  <bensberg@justemail.net>
	* src/rcfile.c (parse_header_exp): Don't continue when something is
	wrong -- skip the rest of the line.  This fixes Savannah bug #47289.
	* src/rcfile.c (parse_header_exp, parse_magic_exp, grab_and_store):
	Use the now correct parsing of header regexes also for parsing magic
	regexes.  This fixes Savannah bug #47292 and saves 50 lines of code.
	* src/rcfile.c (grab_and_store): Rename a variable and densify.
	* src/rcfile.c (grab_and_store): Do not drop regexes that were
	gathered earlier.  This fixes Savannah bug #47285.
	* src/rcfile.c (grab_and_store): Rearrange things in my style.
	* src/rcfile.c (parse_syntax, parse_rcfile): Disallow adding any
	further things to a syntax when an rcfile ends or when an invalid
	syntax command is found.  This fixes Savannah bug #47207.

2016-02-26  Benno Schulenberg  <bensberg@justemail.net>
	* doc/man/nanorc.5, doc/texinfo/nano.texi, doc/syntax/nanorc.nanorc,
	doc/nanorc.sample.in: Correct the description of 'justifytrim', add
	it to the Info document, sort it, and tweak a wording.
	* src/color.c (color_update): Look for a default syntax only when
	all else failed -- forego the small, complicating optimization.
	* src/color.c (color_update): Strip things bare to see the sameness.
	* src/color.c (found_in_list): Factor out this triple repetition.
	* src/color.c (color_update): Rename a variable for conciseness.
	* src/color.c (nfreeregex): Elide this function, now used just once.
	* src/nano.h: Rename a struct element for aptness and contrast.
	* src/nano.h: Rename another element, because it refers not just
	to file extensions, but also to header lines and magic strings.

GNU nano 2.5.3 - 2016.02.25

2016-02-25  Benno Schulenberg  <bensberg@justemail.net>
	* src/browser.c (do_browser): Plug a memory leak by not copying
	a string twice.  This fixes Savannah bug #47206.
	* src/browser.c (do_browser): Now put things in the proper order.
	* src/files.c (make_new_buffer), src/nano.c (splice_opennode): Elide
	the latter function, by handling the two cases (the creation of the
	first element, and the insertion of a new element) directly.

2016-02-23  Benno Schulenberg  <bensberg@justemail.net>
	* src/prompt.c (do_statusbar_output, do_statusbar_delete):
	Rename a variable, for contrast and correctness.
	* src/cut.c (do_copy_text): Don't move the cursor when copying a
	backwardly marked region.  This fixes Savannah bug #46980.
	* src/text.c (do_undo, do_redo): Center the cursor when the
	thing being undone or redone is currently off the screen.
	* src/{files,nano,winio}.c: Rewrap and reshuffle some lines.

2016-02-22  Chris Allegretta  <chrisa@asty.org>
	* Add the ability to kill the trailing spaces when justifying text,
	by adding a new nanorc option 'justifytrim' -- we'll see whether
	this warrants a command-line flag or not.  Now with slightly
	better logic for multi-spaced lines.

2016-02-22  Benno Schulenberg  <bensberg@justemail.net>
	* src/nano.c (free_openfilestruct): Elide this function.
	* scr/global.c (thanks_for_all_the_fish, free_list_item): Condense.
	* src/winio.c (edit_scroll): The amount to scroll is never zero.
	* src/prompt.c (do_statusbar_prev_word, do_statusbar_next_word),
	src/move.c (do_prev_word, do_next_word): Sort these in standard way.
	* src/prompt.c (do_statusbar_output): Don't move too many bytes.
	This fixes Savannah bug #47219 (uncovered by r5655).
	* src/prompt.c (do_statusbar_output): Elide a variable.
	* src/prompt.c (do_statusbar_delete): There is no need for nulling:
	the charmove() already copies the terminating null byte.
	* src/text.c (do_justify), src/winio.c (parse_escape_sequence):
	Show the cursor after a justification and after an unrecognized
	escape sequence, and in the edit window when linting.
	* src/text.c (do_linter): Use the correct column number, also when
	messages are skipped.  And don't mind zero or negative numbers.
	This is a partial fix for Savannah bug #47131.

2016-02-21  Benno Schulenberg  <bensberg@justemail.net>
	* src/files.c (input_tab): If the first Tab added the part that all
	matches have in common, don't require a third Tab to show the list.

2016-02-20  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (get_history_completion): Avoid leaking memory
	when tabbing on a string that does not occur in the history.
	This fixes Savannah bug #47124 reported by Mike Frysinger.
	* src/files.c (input_tab): Parse a character in the correct
	buffer.  This fixes Savannah bug #47199.
	* src/prompt.c (do_statusbar_output): Reduce an allocation to what
	is actually needed.  This undoes the papering-over of above bug.

2016-02-18  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (do_replace_loop), src/text.c (do_int_spell_fix),

	* src/files.c (initialize_buffer_text): Delete redundant assignment.

2016-02-15  Benno Schulenberg  <bensberg@justemail.net>
	* src/files.c (read_file): Free not just the struct but also the
	data it contains, and also when it is the first and only line.
	This fixes Savannah bug #47153 reported by Mike Frysinger.
	* src/files.c (get_full_path): Avoid losing a buffer when getcwd()
	fails. 	This fixes Savannah bug #47129 reported by Mike Frysinger.

2016-02-14  Benno Schulenberg  <bensberg@justemail.net>
	* src/search.c (do_replace_loop): Make iterating through replacement
	matches behave again like iterating through search matches: showing
	them centered when found offscreen.  This fixes Savannah bug #47127.
	* src/text.c (do_int_spell_fix): Restore the above behavior also for
	the internal spell fixer.
	* src/prompt.c (do_statusbar_input, do_statusbar_verbatim_input,
	do_statusbar_output): Do the copying from input to output just once.
	* src/prompt.c (do_statusbar_output): Rename and condense some stuff,
	and correct the main comment: filtering means allow_cntrls==FALSE.
	* README, TODO, doc/man/{nano.1,rnano.1,nanorc.5}: Say that 2.5.x
	is a "rolling" release, lock files are done, and prepare for 2.5.3.

2016-02-13  Benno Schulenberg  <bensberg@justemail.net>
	* src/browser.c (do_browser, browser_refresh): Rebuild the file list
	only when necessary, not for each and every cursor movement.  This
	fixes Savannah bug #47133.
	* src/files.c (save_poshistory): Allocate enough space for printing
	out the line and column numbers.  This fixes Savannah bug #47135.
	* src/*.c: Switch the cursor on and off at the appropriate moments,
	so that it no longer shows in the help screen nor in the file list.
	This fixes Savannah bug #47126.

2016-02-11  Benno Schulenberg  <bensberg@justemail.net>
	* src/text.c (do_linter): Go to the next item in the list before
	freeing the current one.  This fixes Savannah bug #46796.
	* src/text.c (do_formatter): Don't leave curses mode, as that would
	hide any error messages upon reentry.  And if there are any messages,
	allow the user a little time to read them.
	* src/text.c (do_linter, do_formatter): Condense some declarations,
	rewrap some lines, and improve a few comments.
	* doc/syntax/go.nanorc: Make the formatter command more visible.

2016-02-10  Benno Schulenberg  <bensberg@justemail.net>

	* src/files.c (update_poshistory): Don't put files in the history list
	when they have the default cursor position (line 1, column 1).
	* src/files.c (write_file): Avoid a pointless lstat() when not writing
	to a temp file, and in the bargain elide two variables.
	* src/files.c (write_file): Elide an unneeded 'if'.

	always the same, and that are global variables anyway.
	* src/prompt.c (update_bar_if_needed): Rename this for more contrast.
	* src/prompt.c (do_statusbar_backspace): Avoid updating the bar twice.

2016-01-29  Benno Schulenberg  <bensberg@justemail.net>
	* src/files.c (do_insertfile): Do display the buffer when configured
	with only --disable-histories.  This fixes Savannah bug #47011.

	* src/*.c: Adjust some indentation and some line wrapping.
	* src/prompt.c (do_statusbar_prev_word): When in the middle of a
	word, jump to the start of the current word, not to the start of
	the preceding one.  This fixes Savannah bug #46970.
	* src/prompt.c (do_statusbar_next_word): Use simpler algorithm.

2016-01-25  Benno Schulenberg  <bensberg@justemail.net>
	* src/files.c (update_poshistory): Handle an update of the first

	* src/utils.c (get_homedir): Don't use $HOME when we're root, because
	some sudos don't filter it out of the environment (which can lead to
	a root-owned .nano/ directory in the invoking user's home directory).
	It fixes https://bugs.launchpad.net/ubuntu/+source/nano/+bug/1471459.

2016-01-07  Benno Schulenberg  <bensberg@justemail.net>

	* src/global.c (assign_keyinfo): Add a comment and use a symbol.

2016-01-04  Benno Schulenberg  <bensberg@justemail.net>

	* src/text.c (do_deletion), src/nano.c (do_input): Let reset_multis()
	figure out whether after a deletion a full refresh is needed, before
	doing a redraw of the current line.  This fixes Savannah bug #46794.
	* src/nano.c (do_output): Let reset_multis() figure out whether after
	an addition a full refresh is needed (for multiline-regexes' sake),
	instead of doing it always.

2015-12-30  Benno Schulenberg  <bensberg@justemail.net>
	* src/nano.c (main), src/files.c (open_buffer): Don't try to position
	the cursor when opening a buffer failed (because the user specified a
