Benno Schulenberg 1c4dd79b9b files: trigger the Easter egg only when "zzy" is typed at the prompt
When the user mentions the file "zzy" on the command line,
the magic spell "Xyzzy" does not actually get typed, so the
Easter egg should then not be triggered.

Benno Schulenberg ad1331527e color: when syntax coloring is toggled back on, calculate multiline data
This will not catch all cases, but at least it will precalculate the
data when syntax coloring was toggled off (M-Y) while in one buffer
and then toggled back on after having switched to a new buffer.

Benno Schulenberg 1bbf07b27e color: avoid allocating emptiness when there are no multiline regexes
When a file is saved under a different name, and as a result the
applicable syntax changes, and the old syntax had multiline regexes
and the new syntax doesn't, then the call of precalc_multicolorinfo()
in write_file() should not result in nano setting up a multicache of
zero bytes for each line in the buffer.

(Problem was found by locally letting nano crash when zero bytes are
allocated, and then happening to rename a file.py to a file.sh.)

Benno Schulenberg d4ee6a2b53 options: rename --tempfile to --saveonexit, to be far clearer
A long option should describe what it does, not vaguely hint at it.

Also, in several places of nano's code we deal with actual temp files,
and then having a flag called TEMP_FILE that doesn't have anything to
do with temp files is somewhat confusing.

Benno Schulenberg af062af490 docs: mention that doing a full-buffer operation wipes away all anchors 2020-04-30 18:58:17 +02:00
Benno Schulenberg 4bdd6013b0 anchor: do not let piping and spelling transfer an anchor to the top
Just let all anchors disappear when doing an external spell check or
formatting or piping the buffer through an external command, because
leaving just a single anchor on the top line is useless.

This fixes https://savannah.gnu.org/bugs/?58273.

Bug existed since commit 732cf887 from one month ago.  That code
causes an anchor to persist at the point where lines are removed.

Benno Schulenberg 11f099e1da anchor: during full justification preserve anchors as during single ones
When a single paragraph is justified, any anchor on any of its lines
gets moved to its first line.  Let a full justification do the same
for each of the paragraphs.

This fixes https://savannah.gnu.org/bugs/?58272 in a better way.

Benno Schulenberg d1e1438ca0 tweaks: delete some unneeded code, and rename the function accordingly
When set_colorpairs() is called, no files have been loaded yet, so
no syntaxes will have been loaded yet either.  Thus it is pointless
to run through the list of available syntaxes.

Benno Schulenberg bc4240dda5 tweaks: rename a function, to better describe what it does
Its major function is to find an applicable syntax, if there is any.
And if the syntax hasn't been used before, to prime its color pairs.

Also, reshuffle a line to be able to elide an #ifdef.

Benno Schulenberg fd70c25d21 menus: remove unneeded words and shortenings from key labels
In "Cut Text" and "Paste Text" the word "Text" is superfluous.  (It
could even be called slightly misleading, because by default ^K will
cut the current line, whether or not it contains text.)

The "Get Help" is of course inherited from Pico, but to me it has
always sounded a bit as if it would go search help on the internet.

Instead of "Spelling" I would have preferred "Spellcheck", but that
gets a bit too cramped on an 80-column terminal.

For ^C I've chosen "Location" because I tend to understand "Position"
as a verb, especially when seen next to "Go To Line" (even when having
two items with the same meaning next to each other doesn't make sense).

"Mark Text" has simply always been wrong.  It doesn't mark anything,
but just *sets* the mark (or unsets it, but that normally happens
automatically, no need to mention that in the label).

The "Cut Till End" and "Full Justify" get shown only on very wide
terminals, and at such widths there is enough room for each label
to write out those two labels in full.

Marco Diego Aurélio Mesquita f091c34bac new feature: bindable functions for toggling and jumping to "bookmarks"
With the 'bookmark' function, the user can place a bookmark on any
line in the buffer.  Multiple lines can be bookmarked in this way.
With 'prevbookmark' and 'nextbookmark', the user can then easily
return to the bookmarked lines.  The search for a bookmark wraps
around, as if start and end of buffer are connected.

[However, in this implementation, when a bookmarked line is deleted,
the bookmark is deleted too.  This is undesirable.  Also, when such
a deleted line is pasted elsewhere, the bookmark reappears with it,
and when pasted multiple times, the bookmark will be there as many
times.  This is thoroughly undesirable.  These behaviors will be
changed in a later commit.]

A bookmark is not yet visible in any way.

This fulfills https://savannah.gnu.org/bugs/?57577.
