Benno Schulenberg 4d77e0adbb speller: prefer 'hunspell' over 'spell', because it can handle UTF-8
Also, 'hunspell' is sensitive to the 'LANG' environment variable,
so that spell checking will take place for the language that the
user is using, instead of always for English.  (This is a behavior
change, and some people may not like it, expecting the spell check
to occur always for English, but... we'll see.)
2019-11-25 16:57:04 +01:00
Benno Schulenberg 576502a5c5 speller: when 'spell' is not found, try running 'hunspell -l' instead
This increases the chances that spell checking will work out of the box,
without any extra installing or configuration.

Benno Schulenberg f230c46e5e tweaks: drop the unneeded closing of descriptors when exiting anyway
Also, when something goes wrong in the later stages of the pipeline,
the error code would try to close descriptors that are already closed,

that are still open.

Benno Schulenberg 2b9f06194f formatter: don't let output from the program pollute the screen
Run the formatting program outside of curses mode, so that any output
(complaints) that it produces will be on the terminal after exiting
from nano -- at least on a terminal emulator, not on a Linux VT.

This also allows the formatter to be an interactive program.

The disadvantage is that the screen flickers when typing M-F.

Benno Schulenberg a6dae403e6 formatter: accept the formatted result also upon a nonzero exit status
For a nonzero exit status of the formatting program, report on the

reformatted text anyway -- it can be easily undone with M-U.  Only
report failure when the intended program could not be run.

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 fa88fcc8f2 tweaks: rename a function, and elide a parameter that is always NULL
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter.  So, drop that parameter and remove the
chunk of code that handles it.  Also rename the function, as there are
already too many functions that start with "parse".

Benno Schulenberg 34170611d3 restored feature: a per-syntax 'fixer' command that processes the buffer

Benno Schulenberg 0374708597 undo: put the cursor back on the original row for a full-buffer operation
When an operation that replaces the entire buffer is undone, the
position of the viewport is lost.  Compensate for this by storing
the row of the cursor in the undo item, and, after executing the
undo item, arranging the viewport so that the cursor is back on
the original row -- the row where the operation was invoked.

Benno Schulenberg d12191db5a tweaks: pass any special undo/redo messages to the add_undo() function
For the three operations (justification, spell checking, and filtering)
that need to undo or redo two suboperations (cutting and then pasting)
in one go, pass the message that describes the operation to add_undo(),
so that the undo item does not need to be modified after the call.

This looks better, but does add some twenty NULL parameters elsewhere.

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 781c7a7a5f chars: create a dedicated function for getting the length of a character
Instead of calling in twenty places parse_mbchar(pointer, NULL, NULL),

unneeded parameters onto the stack, avoids two needless ifs, and elides
an intermediate variable.

Its main purpose will follow in a later commit: to speed up searching.

Benno Schulenberg f03c87c300 tweaks: squeeze excess spaces out of a line in situ

Benno Schulenberg 8582e4a6b9 tweaks: don't bother keeping track of whether a squeezed line has shrunk
When squeezing excess spaces from a line has proved unsuccessful, we

old data, so that we can simplify things.

Benno Schulenberg e3e81879b1 tweaks: condense the setup of the two signal handlers for Ctrl+C
Don't bother checking for an error from sigaction(), because the only
things it could error out for is when it is passed an invalid signal
(which SIGINT isn't) or oldaction/newaction would point to memory that
is outside of nano's control (which is obviously not the case).

Also, the setup of signal handlers during startup does not check for
errors, so why do it here?

Benno Schulenberg 12bf3bfce4 feedback: don't clear off possible error messages after a spell check
If functions deeper down would put up some message on the status bar,
it should not be cleared.  The chance that messages from a spell-check
program stay onscreen is minute: the edit window is fully refreshed,
the status bar is fully drawn, and the help lines (if there are any)
are redrawn.  Only the title bar is not refreshed, but the chance that
an error message has spilled onto the top row...  And anyway, the
spell checker should not print any error messages at all.

Benno Schulenberg 404a6862cd tweaks: really don't bother renumbering the lines in the cutbuffer
The lines from the cutbuffer will be renumbered when it matters: when
they get pasted.

The only place that used the numbering of (a copy of) the cutbuffer
(the updating of an undo item) already iterates through its lines.
Just add a counter there instead of making use of the line numbers.
2019-05-01 13:09:22 +02:00
Benno Schulenberg 85fc41470b tweaks: stop passing 'cutbuffer' and 'cutbottom' back and forth
All extractions are done into the cutbuffer, so it is pointless to pass
'cutbuffer' and 'cutbottom' in and back out as parameters all the time.
Just use those global variables directly.

Also, rename the function as there is no longer a buffer among its
parameters.
2019-05-01 11:33:37 +02:00
Benno Schulenberg 2b9dd6c574 tweaks: don't bother saving and restoring 'cutbottom' all the time
The 'cutbottom' variable is only ever used when cutting or copying
consecutive lines: for appending the current line to the already
existing lines in the cutbuffer.  As soon as some other operation
is performed, 'cutbottom' becomes irrelevant, it could be set to
anything, it doesn't matter: the pasting of the cutbuffer does not
use the value of 'cutbottom', nor does any other operation.

Benno Schulenberg fcad442d80 tweaks: declare a function as const and let its allocated string leak
Avoiding this leak is more trouble than it's worth: invocation_error()
will be called seldomly, and when it is called, the user will probably
quickly exit from nano to fix things.

Also declare the speller functions as const again, so they don't give
the impression that their result can be freed.

Benno Schulenberg 34d22d3f00 wrapping: improve the persistence of the prepending behavior
Now you can have a look elsewhere in the buffer (and even delete
or paste stuff there) and when you return to the original line
and continue typing, any spillover from automatic hard-wrapping
will spill over onto the same line it spilled over to before.

You can even switch to a different buffer and return and continue
typing, and stuff will still spill over to the same line.

In the bargain, this gets rid of a bit of flag-resetting code
that was run for many keystrokes, in most cases needlessly.

Benno Schulenberg e8f69e40d1 wrapping: add a missing space only when the remainder will be prepended
When automatic hard-wrapping causes some piece of a line to be pushed

of this piece only when this piece actually gets prepended.

Benno Schulenberg 1c707d4f99 unindent: ensure that a partial line gets displayed properly afterwards
When only the trailing chunk of a line is displayed on the top row of
the screen, and the unindenting of this line leads to a reduction in
the number of chunks, then the starting point of the viewport needs
to be re-evaluated.  For simplicity, do this always when something is
unindented.
