Benno Schulenberg 308d6e73e3 tweaks: normalize whitespace, drop unneeded prototype, condense comment 2021-11-07 15:51:32 +01:00
Benno Schulenberg 167c93b85c justify: correctly determine whether top-of-buffer has been reached
The text to be justified has been excised from the buffer and is now
in the cutbuffer, so we cannot compare any of its lines to 'filetop'.

This fixes https://savannah.gnu.org/bugs/?61438.

Benno Schulenberg fab4d0afcb tweaks: reshuffle a coloring rule, to have related ones together
(We don't want the rule for control codes after the rule for comments,
because then control codes in commented-out binds would stand out.)

Benno Schulenberg d9e42cb274 syntax: nanorc: require whitespace before the start= and end= keywords
Also, drop the unneeded and mistaken 'end=' in the first regex, as
a coloring rule with just end="something" is not valid.  And drop
the requirement for having trailing whitespace or nothing at all,
as it does not constitute a useful restriction.

Also, fold two regexes together, for economy.

Benno Schulenberg 4d9be13316 syntax: nanorc: add 'execute' menu for unbind, and drop a bad constraint
The coloring rule for 'unbind' still checked for the old 'extcmd' and
'externalcmd' menu names.  And not coloring binds and unbinds as valid
when followed by something other than a comment was overrestrictive,
because the bind or unbind command would work just fine.

(Nano silently allows trailing garbage on any line without a regex.)

Also, take the opportunity to order the menu names in the bind and
unbind rules in the same way.

Benno Schulenberg 83f94a88df suspension: enable ^Z by default -- ignore -z option and drop M-Z toggle
In the beginning, the goal for nano was to be a drop-in replacement for
Pico.  Pico did not know a Suspend command, so the ^Z keystroke needed
to be conditionalized on an option (-z or --suspend or the toggle M-Z),
just like the ^S and ^Q keystrokes (for stopping and resuming terminal
output) were conditionalized on --preserve.

But nano has abandoned full Pico compatibility since version 4.0.  It
is time to unconditionalize ^Z as well.  This should not be a problem:
Debian and Ubuntu have had 'set suspend' in their /etc/nanorc for years,
so a considerable portion of nano users have had ^Z enabled by default
for a long time, and no one seems to have complained.

If the keystroke bothers some user, they can unbind it in their nanorc.
They will still be able to suspend nano through the Execute menu: ^T^Z.

This addresses https://savannah.gnu.org/bugs/?61372.

Benno Schulenberg 8762e04631 replacing: keep the spotlighting, also after toggling the help lines

Benno Schulenberg 256a0d670e replacing: keep centering the occurrence, also after toggling help lines

Benno Schulenberg 50106266bc pasting: when less than a line is pasted, allow automatic hard-wrapping
When --breaklonglines is in effect and the user pasted just a few words
(anything without a linebreak), then act as if this short text had been
typed by the user and hard-wrap the line when it became overlong.

This fulfills https://savannah.gnu.org/bugs/?61353.

Benno Schulenberg 33041d0ad5 statusbar: count words in the way that matches how Ctrl+Right moves
When --wordbounds (-W) is active, nano considers punctuation as
word-forming characters and will thus count words the same way
as 'wc -w' does.  This is how nano counted words until now.

But when --wordbounds is not active (the default), only letters
and digits will be considered word-forming and thus lone groups
of lines and dashes and other punctuation will not be counted
as words, which is more like how a human would count words.

Benno Schulenberg 7bd68365ec syntaxes: avoid coloring "this\" as if it were a valid string
A backslash should not be allowed inside a quoted string unless
it is used to escape another character.

This fixes https://savannah.gnu.org/bugs/?61389.

Bug existed since each of these syntaxes was introduced.

(Awk and Fortran do not know include files with names between
angled brackets, so those regexes are dropped in the bargain.)

Benno Schulenberg 485eb18d83 syntaxes: use one regex for coloring quoted strings, to avoid overlap
Quoted strings cannot start within another quoted string and end after
that other string has ended.  Therefore single-quoted and double-quoted
strings should (as much as possible) be colorized by a single rule, so
that overlapping colorations are avoided.

(This also fixes a double typo in the PHP syntax (\. --> \\.) that has
been there since the PHP syntax was added in 2008, commit 90ee8ee4.)

This fixes https://savannah.gnu.org/bugs/?61387.

Bug existed since each of these syntaxes was introduced,
the oldest ones around 2006, a few others around 2015.

The one that got it right was the Lua syntax from 2011.

Also, when colorizing double-hashed comments specially anyway,
avoid colorizing ##.* as a single-hashed comment.

Benno Schulenberg e52c81f5db syntax: nanorc: improve the file-matching regex
The "\.?" part was pointless.  It says that the string "nanorc"
*might* be preceded with a period.  Sure, but if the period is
absent, then anything else may be there too, so the optional
period gives zero restriction.

The restriction should be: either the filename has the extension
".nanorc" OR the full filename is "nanorc".  So the "nanorc" part
must be preceded by either a period or a slash.

(However, in the times of commits 3dc0e23e and dc9c40a5, fifteen
and eighteen years ago, it was still the user-provided filename
that was matched against the regex, not the full-path filename.
The latter method arrived in commit ec8d51be, six years ago.)

Benno Schulenberg d57bfc057f syntax: rust: do not colorize as string the text between two strings
Strings may not contain a double quote unless it is escaped.

Reference:
  https://doc.rust-lang.org/reference/tokens.html#string-literals

(This will still not colorize multi-line strings with an unescaped
newline, will still colorize "this\" as if it were a valid string,
and will still miscolor things when there is another string after
the closing quote of a two-line string.  But those things can't
be helped -- line-based regexes cannot emulate a full parser.)

Benno Schulenberg 0dbe857ba2 syntaxes: undouble the backslash within bracket expressions
Within a bracket expression, the backslash is not special,
so it does not need to be escaped.

The double backslashes within brackets were found with:

Also, incorporate the square brackets into some bracket expressions
by listing the closing bracket first, saving a separate regex for
those two brackets.

result a detailed table of contents at the start of the HTML page.
