Benno Schulenberg 77ca8735ab syntax: nanorc: colorize "light" as valid only for the eight basic colors
Only the basic colors (like red, blue and yellow) can take the prefix
"light" or "bright", not the extra colors (like pink, lagoon and lime).

This fixes https://savannah.gnu.org/bugs/?60674.

Bug existed since version 5.0, since the extra colors were introduced.

Benno Schulenberg d1957819c4 bindings: show either "^/" or "^-" in the help lines, instead of "^_"
The "^_" has always been poorly legible (the underscore melting into
the bottom of the terminal) and difficult to type (Shift+Ctrl+minus).
The "^/" is both more readable and easier to type.

In terminal emulators, "^/" is shown, but on a Linux console "^-",
as ^/ does a backspace in the default console key mapping.

Also, allow using "^-" when rebinding ^_ in a nanorc file.

This addresses https://savannah.gnu.org/bugs/?57393.

Benno Schulenberg 544351f3be syntaxes: replace [[:space:]] with [[:blank:]] to exclude carriage return
In many places a carriage return is not valid whitespace and should
thus not be colored as such.  In some of these places a vertical tab
or form feed is maybe valid whitespace, but it would be ugly or even
wrong to color them because they are not part of the subsequent
comment or keyword.

This fixes https://savannah.gnu.org/bugs/?60456.

Benno Schulenberg c275c5158e rcfile: introduce the modifier "bold", for specifying bolding separately
This makes it possible to avoid the misnamed prefix "bright".  It is
misnamed because (on current terminal emulators, when the brightening
of bold is switched off) it just makes the typeface bold, not the color
brighter.  The prefix "light" will now only make the color brigther,
and the modifier "bold" will just make the typeface bold (on terminal
emulators, when the brightening of bold is switched off).

On a Linux console, which is not capable of bolding the typeface,
"bold" will brighten the color.

This fully fulfills https://savannah.gnu.org/bugs/?58503.

Benno Schulenberg 4d10f583e4 rcfile: accept prefix "light" to make a color brighter without bolding it
The prefix "bright" will continue to make the color brighter AND/OR
make the typeface bold (depending on how the terminal is configured
and on its capabilities), but the prefix "light" will just make the
color brighter (if the terminal can do that).

The prefix "bright" continues to do the same as what it did before,
to not change the appearance of user-defined syntaxes.  And having
an option to change the meaning of "bright"... would be confusing.

This partially fulfills https://savannah.gnu.org/bugs/?58503.

* %elif, %elifos, %elifarch  - 'else if' stanzas for conditionals
* %sourcelist                - section for listing sources line by line
* %patchlist                 - section for listing patches line by line
* %generate_buildrequires    - script section after %prep for

An enhancement added in RPM 4.13:

* Sections for file trigger stanzas

(Reference: https://rpm.org/user_doc/file_triggers.html.)

As these are being increasingly used in Fedora and other distributions,
it's quite helpful to have syntax highlighting be up to date on handling

Benno Schulenberg 4281b6becb commands: rename 'fixer' to 'formatter', to be less misleading
The word "fixer" sounds too much as if the command would be able
to fix mistakes or correct errors.  Especially when seen next to
"linter", it sounds as if one does a syntax check and the other
fixes the found mistakes.  (Although the command might in theory
be used for this, it is not its intended purpose.)

Benno Schulenberg 69d2045c9f syntax: nanorc: colorize only lowercase keywords as valid
Nowhere does the manual say that nanorc keywords are case-insensitive,
and none of the examples use uppercase keywords.  So, simply consider
uppercase keywords to be invalid.  This will later allow nano to use
case-sensitive comparisons, which are slightly faster.

Benno Schulenberg f813fd0f4d rcfile: allow binding also F17...F24
For historical reasons the rebinding code allows binding F13...F16,
which on most terminals are typable with Shift plus F1...F4.  But,
at least on an Xfce Terminal, Shift plus F1...F12 produce F13...F24.
On a Linux console, Shift plus F1...F8 produce F13...F20.  So: allow
to bind the full shifted F13...F24 range.  It costs no extra code
and makes things more rounded.

Benno Schulenberg 3644d51b97 new feature: a 'tabgives' command to define what the Tab key produces
The 'tabgives' command is syntax-specific and should be followed by a
string containing the character(s) that a single press of the <Tab> key
should produce -- most likely a single TAB or a small bunch of spaces,
but any string is allowed.  This overrides the 'tabstospaces' option.

When one wants to make sure <Tab> inserts always four spaces and never
a TAB when editing a Python file, one could add to one's nanorc:

  extendsyntax python tabgives "    "

where there are four spaces between the quotes.  And when one wants
to ensure, when editing a Makefile, that <Tab> always inserts a TAB
and never spaces, independent of what tabstospaces is set to, one
could add to one's nanorc:

  extendsyntax makefile tabgives "	"

where there is a literal TAB character between the quotes.

Benno Schulenberg bdf1a9d4e7 syntax: perl: avoid upsetting older glibcs with crafty range expression
The regcomp() function from glibc-2.27 (and older) considers the
bracket expression ['-.] to be invalid -- mistakenly.  Avoid using
any range expression in the relevant regex and instead enumerate
all acceptable characters.

This avoids https://savannah.gnu.org/bugs/?56766.
