Benno Schulenberg 3313fac8eb tweaks: remove redundant pair of parentheses, and swap two alternatives 2021-10-25 12:45:45 +02:00
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 0f40752139 docs: add a hint about making ^L do just 'refresh' to the sample nanorc
Just for the sake of completeness -- I doubt anyone ever uses Refresh.

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.)

This fixes https://savannah.gnu.org/bugs/?61361.
Reported-by: Elias Jonsson <e@ejon.eu>

Bug existed since version 2.6.1, since the Rust syntax was introduced.

Benno Schulenberg 918ce1afa3 tweaks: just let do_wrap() set 'refresh_needed' instead of returning TRUE
This gets rid of performing an action in the condition of an 'if'.

Benno Schulenberg 440f39e558 docs: correct the description of the layout -- four areas, not five
Also, remove the concept of "shortcut list", as there is no need.
Just use "two help lines" instead, like elsewhere.

Benno Schulenberg 108c84daf8 docs: move the chapter about editor basics into third position
Or rather, move the chapter about command-line options to between
the chapters on file browser and feature toggles.  Also, rename the
chapter about the built-in help, and move the section about screen
layout to be the first in the editor-basics chapter.

Benno Schulenberg bc4a141cba tweaks: mark keystrokes consistently with @kbd in the manual
The @key command has the same visual result in the Info output, but
looks different (non-italic) from @kbd in the HTML and PDF outputs.

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:

  grep -o  '\[[^][]*\\\\[^][]*\]'  syntax{,/extra}/*rc

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

Benno Schulenberg 483538f8f3 syntax: email: use a character class, as \s does not work inside brackets

Benno Schulenberg 1f36d5411a docs: improve the title of the manual, away from the bare "nano"
Also, suppress two unwanted blank lines in the HTML output, and
use a macro to avoid repeating the same three lines eight times.

Benno Schulenberg 46f76ca8b8 docs: avoid large Table of Contents at top of HTML version of manual
Texinfo-6.8 (that was used to build the docs of nano-5.9) changed
the way the @contents command is processed for HTML output, with as
result a detailed table of contents at the start of the HTML page.
That is ugly and too much detail.  To avoid that, produce a table
of contents only when generating output meant for printing.

This fixes https://savannah.gnu.org/bugs/?61344.

Bug existed since version 5.9.
2021-10-17 16:55:24 +02:00
Benno Schulenberg 3a09577e0c tweaks: replace the obscure @* with the slightly clearer @sp
What @* does is guesswork when you don't use Texinfo regularly.
That the "sp" in the @sp command refers to vertical space is not
very clear either, but the command is used on nearby lines too,
so better use it more.

Also, improve two wordings and fix a four-year old typo.

Benno Schulenberg b9f472a905 syntax: texinfo: be more precise in colorizing @commands
An @command must either start at the beginning of the line and be
followed by whitespace or EOL, or it must be followed by a brace.
Colorizing just any "@text" string colored too much.

Benno Schulenberg 557d8131ca docs: prevent a black square in the PDF after the long synopsis line
Also, prevent an unwanted break in a keystroke.

Benno Schulenberg 89fd11109d docs: add a meta description for the HTML rendering of the manual
Also, drop the Emacs mode line -- we don't use Emacs,
and Emacs doesn't need it.
2021-10-16 17:03:45 +02:00
Benno Schulenberg badf3edc55 syntax: texinfo: colorize the special @-plus-punctuation commands too
Also, allow an @} and another @command{} within a pair of braces,
colorize only the valid @-commands with uppercase in their names,
unbold enclosed command arguments, colorize the directory entries
for the manual, and properly colorize also the comments that use
the full @comment command.

Reference:
  https://www.gnu.org/software/texinfo/manual/texinfo/html_node/Command-List.html

Testing was done with:
  info texinfo @-C "Command List" --output=list
  sed -i -e "s/^'//" -e "s/'$//" list
  nano list -Ytexinfo

Benno Schulenberg 36e3284979 help: ensure there is a blank line between title bar and start of text
In olden times, each help text started with a title line in the text
window followed by a blank line.  But since version 2.8.2, since the
help texts have become almost regular buffers (and thus searchable),
the title of the help text is in the title bar, and since version 4.0,
since --morespace became the default, the text will start immediately
below it.  But a title line immediately followed by text, without a
blank line between them, does not look nice.  So, add such a blank
line back when not using --emptyline (and also when using --minibar,
because the top of the terminal window is like a title bar).

Benno Schulenberg f9468fa987 history: process file faster by not filtering out hypothetical duplicates
When the history file has been created by nano, it will not contain
any duplicate search or replace strings, nor duplicate commands, so
checking for such a duplicate for each read item was a waste of time.

And if the user edited the history file and created duplicates, who
are we to filter them out?  They will not cause the history mechanism
to malfunction; they just take a little extra memory.

Benno Schulenberg 30abc02277 tweaks: reshuffle two conditions, re-indent, and rewrap a line
If all is programmed well, then the functions 'get_older_item' and
'get_newer_item' will only occur when a history list is passed to
acquire_an_answer().  But let's keep it certain we don't dereference
a NULL pointer.

Benno Schulenberg 77457fa6e9 prompt: avoid resetting the history pointer when the search is cancelled
When the user immediately cancels a search (^W^C), then nothing in
the history stack has changed, so then there is no need to reset the
history pointer to the bottom.

This slightly improves the fix for https://savannah.gnu.org/bugs/?61316.

Benno Schulenberg 87cde1590d tweaks: elide two functions that each were called just once
This also gets rid of an assignment in an 'if' clause (twice),
elides a local variable, and makes it clearer that a pointer
gets moved to the previous or next item (instead of hiding it
as a side effect of the function call).

Benno Schulenberg 8ef74b3aac tweaks: rename five empty functions, to get rid of a meaningless suffix
For consistency, these five names ought to start with "flip_", but
then the bindable functions would need to be renamed too, and that
would be annoying for the user, *and* it would create too many names
that start with "flip" -- it wouldn't be distinctive any more.

Benno Schulenberg bc22b3c876 files: clear original filename when the user toggles Append or Prepend
When the current filename is equal to the filename of the buffer,
