Benno Schulenberg 43c6bc6619 tweaks: add a consistency check plus a corresponding warning
Since commit 4c6ec637 from about half a year ago, the 'action' parameter
of update_undo() is unused.  Verify that this parameter matches the type
of the item at the top of the undo stack, so that in another half year
the parameter can be safely removed.

David Lawrence Ramsey 37be9b54ca justify: initialize a variable before making use of its value
When the mark is off, initialize not just 'bot_x' but also 'top_x'.

This fixes https://savannah.gnu.org/bugs/?55898.

Bug existed since the justifying of a marked region was introduced,
four days ago, with commit f7f5514e.

David Lawrence Ramsey 5d7b723c16 justify: put a mid-line marked region onto separate lines
This matches Pico's behavior.  However, Pico doesn't add the quoting +
indentation to the line in which the selection ends, but this is wrong,
so nano does add it.  Also, Pico doesn't account for partial quoting +
indentation at the start or end of a selection, but this is wrong, so
nano does.

David Lawrence Ramsey 053244db70 justify: handle the leading part when justifying a marked region
Unlike a regular paragraph, marked text may have different quotes and
more than two types of indentation.  Handle this by replacing deviant
quotes with the quote of the first line, and deviant indentation with
the indentation of the second line.
2019-03-10 09:22:02 +01:00
David Lawrence Ramsey f7f5514eef new feature: marked text gets justified into a single, new paragraph
This is modelled after Pico's behavior.  However, Pico won't do anything
if you do a full-justify while the mark is on.  But this is unnecessarily
limiting, so, when the mark is on, nano will handle a full-justify and a
plain justify the same.

This currently does not handle the lead (quoting + indentation) in
justified selections, does not put mid-line justified selections onto
separate lines, and does not strip whitespace after the lead in justified
selections, the latter two of which Pico does.  These behaviors are
forthcoming.

David Lawrence Ramsey 311a7138b2 tweaks: adapt find_paragraph()/justify_paragraph() for multiple quotes
Instead of passing 'quote_len' to these functions, calculate it directly

This will be needed when the justifying of marked text is added.  When
unmarked text is justified, it is a single paragraph and by definition
has a uniform quoting part.  But marked text may be a jumble of lines
that have different quoting parts.

Benno Schulenberg 14f32577ee display: ensure that spotlighted text is not treated as a prompt answer
When doing replacements or fixing misspelled words, and edit_refresh()

anything from MREPLACEWITH, MYESNO, MSPELL, or MMAIN.  Make sure it is
always set to the latter just before calling edit_refresh(), so that
display_string() will use the full length and the word gets properly
highlighted.

Benno Schulenberg 500c41b83b tweaks: move the check for beginning-of-paragraph to a better place
Only the first search for a paragraph needs to check whether we're
currently in the middle of a paragraph.  When the 'while' loop for
a full justify is executed, all calls of find_paragraph() start
either on the first line of a paragraph or between two paragraphs.

Benno Schulenberg 2c83047842 tweaks: condense the logic of find_paragraph()

  c) Move forward to the end of the paragraph, if any.

Benno Schulenberg 66cd897dc4 justify: correctly detect when we've reached end of buffer
When, in the 'while' loop for a full justify, 'filebot_inpar' becomes
TRUE, it means that EOF has been reached and find_paragraph() should
not be called again.  To allow 'filebot_inpar' to convey this meaning,
it should not be set to TRUE elsewhere, so another boolean is needed
for setting the correct length of the final line of the cutbuffer.

The removal of the x-coordinate handling affected this.  Reshuffle things

Benno Schulenberg 1f39f60b2f tweaks: there is no reason to block SIGWINCHes while waiting for speller
In the past, SIGWINCHes were responded to immediately (which was madness),
but since commit 75d64e67 all a SIGWINCH does is set a flag so that, when
the time comes to update the screen, nano knows the dimensions may have
changed.  The mentioned commit removed most blockings and unblockings of
SIGWINCH, but not this one.

David Lawrence Ramsey 93c8e316a8 justify: verify being in a paragraph before trying to find its beginning
If find_paragraph() detects that we're not in a paragraph, it moves
forward a paragraph and then backward to that paragraph's beginning.
Make it check whether we're in a paragraph before moving backward
(since there might not *be* any more paragraphs), to prevent going
forth-and-back and never reaching the end of the buffer.

Benno Schulenberg dd9766c2e0 editing: when --smooth is used, make <Enter>-at-bottom scroll one row
When using --smooth or 'set smooth', the screen should scroll the
minimum amount needed to get the cursor back into view.  (The only
exceptions are search, undo, and redo -- when there the cursor goes
offscreen, the cursor line is centered.)

This change brings the behavior of pressing <Enter> on the bottom
row into line with, for example, pasting a single line.  See also

David Lawrence Ramsey 381a386b01 weeding: drop the forreal parameter from place_the_cursor()
Commit 28beb3f added the 'forreal' parameter to prevent spotlight() from
placing the cursor wrongly due to an invalid placewewant.  However, since
the variable-width softwrap overhaul (specifically, since commit 8490f4a),
place_the_cursor() no longer checks placewewant, so the parameter is no
longer needed.

Furthermore, dropping 'forreal' and thus always setting current_y won't
affect the operation of spotlight(), since the only functions that use
spotlight() (do_replace_loop() and do_int_spell_fix()) both call
edit_refresh() beforehand, which means that current_y will already
have been set to the value it will be set to again.

David Lawrence Ramsey 2abe7c03fe text: make sure commenting is disabled when comment "" was specified
When the active syntax contains a comment command that specifies the
empty string, this should override the default comment of "#" and
should disable the Meta-3 keystroke.

To achieve this, the comment string is now set by default to "#" for
all syntaxes, so that it will be set when no comment command is given
(including for the "none" syntax), and is unset only by explicitly
specifying «comment ""» in a syntax file.

This fixes https://savannah.gnu.org/bugs/?51355.

Benno Schulenberg 28beb3f9c5 replacing: don't let placewewant influence the placement of the cursor
When spotlighting the string to be replaced, placewewant isn't valid,
so tell place_the_cursor() to ignore its value to avoid the cursor
getting mistakenly placed at the beginning of the next row.
