Benno Schulenberg 252bb60036 display: highlight the ">"/"<" continuation characters in reverse video
To make it obvious that they are not actual characters in the file.

The default highlighting is in reverse video, but this can be changed
to bold by using --bold or 'set boldtext'.

This fulfills https://savannah.gnu.org/bugs/?55571.

Benno Schulenberg 6d34b8a5cd display: change the "$" continuation character to ">" and "<"
The angular brackets look a bit like arrows and thus hint much more
at the idea of continuation than a dollar sign.

Benno Schulenberg ad505e7fff display: represent half of a double-width character with "[" and "]"
When the screen's edge leaves just one column for a two-column
character, then show its left half as "[" and its right half as "]".

(They used to be shown as ">" and "<", but these characters will be
repurposed in the next commit.)

Benno Schulenberg 757d223064 tweaks: don't bother executing two functions that are empty
The get_history_older_void() and get_history_newer_void() functions
are mere names, they don't actually do anything.  So... don't bother
to execute them, so the 'finished' variable doesn't have to be reset
after calling them.

Also, normalize the order of those two empty functions.

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 5618189643 prompt: trim a double-width character at the screen's edge
It needs to be trimmed and substituted with a single-width placeholder
to prevent the continuation character ">" from getting pushed to the
next row.

Also, use the correct width for the answer so that the continuation
character is only displayed when the answer does not fit any more.

David Lawrence Ramsey edc0d6280a display: properly trim double-width characters at the edit window's edge
When a line ends with a two-column character, and this character straddles
the edit window's edge, then, although we've reached the end of 'buf', we
have exceeded the 'beyond' column and this two-column character needs to
be trimmed from the 'converted' string, otherwise it would get printed on
the next row.

This signals our break from trying to be as compatible with Pico as
possible.  We were already incompatible with modern Pico in the -n
and -W options, and in several character-set and color options, so
ignoring those five options brought us very little.

Anyway, soon some of those options will be reused and will have the
effect of making nano look and behave more like Pico.

When multiple buffers are open, the edit window says "Close" for ^X

when pressing ^X leads to exiting from nano.  Pressing ^X in the file
browser does not exit from nano, so make it say "Close" instead.

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.

This fixes https://savannah.gnu.org/bugs/?55086.

Benno Schulenberg 95dd873205 bindings: no longer bind F13 and F14 and F15
The bindings for F1 to F12 are there for compatibility with Pico.
But Pico does not know anything about F13 to F16; for unknown reasons
they were added to nano.  They seem hardly useful: normal keyboards
do not have the F13 to F16 keys, and very few people know that they
can "produce" those keys by holding Shift with F1 to F4.  But typing
Shift plus F1 to F4 are just as "hard" as, for example, M-G and M-W,
so why anyone would want to use the first ones...?  Especially since
many other functions of nano can only be accessed through Meta and
Control combinations.

Furthermore, F13 to F15 haven't been shown in the help texts since
version 2.3.3, so for more than four years no new user will have
learned about those keystrokes.

The rare user who wants these strange bindings can easily make them
herself.

paragraph length (which it should get from find_paragraph()), and
runs the paragraph at (current, current_x) through justify_format().

David Lawrence Ramsey 076bc31ce5 tweaks: simplify by using a 'do/while' loop instead of 'while (TRUE)'
The do/while loop will run once when doing a justify, and enough times
for the entire file when doing a full-justify.

David Lawrence Ramsey 22c8ef6c39 tweaks: reshuffle some code to avoid several checks for having justified
Move some fragments out of the justifying loop, and adjust/clarify comments
to account for the changes.  This will allow some of the code to be cleaned
up and simplified in the next commits.

Benno Schulenberg c8852aa5e2 help: add a relevant explanatory text for the linter
This fixes https://savannah.gnu.org/bugs/?54713.

Benno Schulenberg 52ba76b2a2 help: show <PgUp> and <PgDn> instead of F7 and F8 for pagewise scrolling
The dedicated editing keys make sense, whereas the function keys are
bound only for compatibility with Pico.

Benno Schulenberg 5bb2b5c08a help: move the linter to the end, to restore pairing in the help lines
Items that are (vaguely) related should be one above the other.

Benno Schulenberg 062b6691bb tweaks: drop the checking of two flags that can no longer be toggled
Also, remove a superfluous condition, and swap two others.

Benno Schulenberg f4c958e810 bindings: allow using ^X to exit from the linter
One can use ^X to exit from the file browser and from the help viewer,
so...  For symmetry.

Benno Schulenberg 4b32c62674 tweaks: reshuffle some lines to get standard order (first up, then down) 2018-09-29 09:46:05 +02:00
Benno Schulenberg b4b9e9b012 linter: allow using <Ctrl+Up> and <Ctrl+Down> to jump to other message
These are more "natural" keystrokes for jumping than <PgUp> and <PgDn>.

Benno Schulenberg 0b63de335e tweaks: elide a wrapper function that is no longer useful 2018-09-28 20:09:12 +02:00
Benno Schulenberg 628eef28b3 bindings: make the linter separately accessible, through M-B by default
This allows running the speller (default binding: ^T) also on files for
which a linter has been defined.  This makes it possible to spell check
comment blocks in source files, for example.

This fulfills https://savannah.gnu.org/bugs/?54711.

David Lawrence Ramsey bed997171c speller: restore the mark coordinates slightly later
To avoid a confusing mishighlighting of just part of a marked region.

Benno Schulenberg 8d0b7a490d undo: move another piece of checking to the two places that need it
And in the bargain get rid of a function that is used just once.

Benno Schulenberg efa323ec88 tweaks: improve two comments, and reshuffle a line for consistency

Benno Schulenberg 4c6ec6377f undo: move some special checking code to the one place that needs it
Only for BACK and DEL was the first call to update_undo() -- all other
types of action would call add_undo() first, so for them the action in
update_undo() would never be different, but the line number might have
changed (like for ENTER and INSERT), so for them exceptions needed to
be made, which was wasteful.

Benno Schulenberg c545438a5f bindings: drop M-| as a keystroke for 'cutwordleft' -- set it free again
The binding was made only to have *something* bound by default to the
'cutwordleft' function.  But now that <Ctrl+Shift+Delete> is available
*and* visible in the help text, the M-| binding is superfluous.
2018-09-23 20:21:57 +02:00
Benno Schulenberg e998814bbc help: show the keystroke <Ctrl+Shift+Delete> as "Sh-^Del"
And in the bargain always return a fixed code instead of searching for
a keystroke that is bound to 'cutwordleft' (which might fail).
