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 6e960012c2 tweaks: split justify_paragraph() into three separate functions
concat_paragraph() concatenates a paragraph into a single line, and
rewrap_paragraph() rewraps that line into multiple lines again.

These two will be needed when the justifying of marked text is added.
2019-03-10 09:22:02 +01:00
David Lawrence Ramsey 311a7138b2 tweaks: adapt find_paragraph()/justify_paragraph() for multiple quotes
Instead of passing 'quote_len' to these functions, calculate it directly
in them.

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()
is called to highlight the relevant word, then the current menu can be
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

  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.

David Lawrence Ramsey ba8462a458 text: properly check again for no paragraphs after the current line
The removal of the x-coordinate handling affected this.  Reshuffle things

it at the beginning of the function before we move) without having to set
'quote_len' and 'par_len' unnecessarily.

Also, adjust some comments accordingly.

David Lawrence Ramsey 4af81823e2 text: make find_paragraph() work on any buffer
Move detecting the final line of the paragraph to find_paragraph(),

applies to the current buffer.

David Lawrence Ramsey 9aa382e69e text: make justify_format() work on any buffer
The function assumes that it works on the current buffer by handling
'totsize' and the mark.  Remove this handling to make the function
more general, which is needed to make it undoable eventually.

This breaks the function somewhat.  Fixes for this are forthcoming.
