Benno Schulenberg a9b5a0e029 tweaks: rename a function to something less abbrevy
Also, swap the logic around, to use less braces.

Benno Schulenberg 026393a91a binding: use plain codes instead of function calls for the jumping keys
Which is possible because those keycodes are hard-bound to the relevant
functions.

Benno Schulenberg db897b574f input: detect again when both Shift and Ctrl are being held on a VT
In nano 2.7.1 and 2.7.2, pressing Shift+Ctrl+Arrow on a Linux console
would behave as if Shift wasn't held.  It got broken three months ago,
by commit 08cd197b, messing up the proper order of the checks.

This fixes https://savannah.gnu.org/bugs/?49906.

Benno Schulenberg 2b1bc6866a input: don't crash when receiving a KEY_CANCEL
On some systems, typing ^C apparently results in a KEY_CANCEL in
the input stream, which gets hard-bound to the do_cancel function.
But in the main menu there is no Cancel function.  So... in that
case, let it fall back to the plain old Ctrl-C code: 0x03.

Benno Schulenberg 1cb6619d6a undo: there are just two forms of deletion: backspacing and deleting
A third method does not exist.

Benno Schulenberg 79a4bf81dc tweaks: rename five variables, for uniformity with a few others 2016-12-19 19:58:15 +01:00
Benno Schulenberg b77e6bd99d general: simplify the detection of a SIGWINCH
There is no need for a counter, nor an old counter to compare it with.

Benno Schulenberg 2bcc6d7f66 tweaks: start searching at a better place
Taking the terminating newline into account, and that there is
at least one digit per number.

Benno Schulenberg cd705a7c4c tweaks: elide a counter and a comparison
For clarity and a tiny bit more speed.  Also rename some variables.

Benno Schulenberg ecd18c1694 history: search for the two position numbers from EOL instead of BOL
A filename might contain spaces, so we can't look for the numbers
(the second and third elements) starting from the head of the line
-- we have to start at the tail and work backward.

This fixes https://savannah.gnu.org/bugs/?49879.

Benno Schulenberg bc8a3a50a4 tweaks: rename three variables, for visibility

Benno Schulenberg f915a28d30 tweaks: don't bother trimming the final newline from a position item
It is irrelevant -- the line is discarded as soon as the data has been
extracted.

Benno Schulenberg cb3fc8892a tweaks: rename a variable and rewrap two lines 2016-12-18 16:34:19 +01:00
Benno Schulenberg 06d9ee89e5 history: encode newlines in filenames as nulls
So they will not break a line in the positionlog file in two.

(Strangely, the reading in of such a log file already decodes
nulls back into newlines.)

This fixes https://savannah.gnu.org/bugs/?49877.

Benno Schulenberg 0b0b812206 files: don't change embedded newlines into nulls in filenames
Because changing anything to a null effectively means to truncate
the name.

This fixes https://savannah.gnu.org/bugs/?49868
and fixes https://savannah.gnu.org/bugs/?49874.

Benno Schulenberg eafae5d417 screen: show an embedded newline in filenames as ^J instead of ^@
The byte 0x0A means 0x00 *only* when it is found in nano's internal
representation of a file's data, not when it occurs in a file name.

This fixes the second part of https://savannah.gnu.org/bugs/?49867.

Benno Schulenberg dfff78dffe titlebar: always pass a pathname through display_string()
So that embedded control characters will be represented
instead of acted upon.

This fixes the first part of https://savannah.gnu.org/bugs/?49867.

Benno Schulenberg d7af590c6b memory: don't bother making a snug fit for things that will be freed soon
Most full paths are needed only temporarily and will be freed within
milliseconds.  Only 'full_operating_dir' and 'backup_dir' continue to
exist for the whole current session.  Any partition, too, will soon be
unpartitioned, so the extra reallocation is just a waste of time.

Benno Schulenberg 8c7e4f5108 tweaks: rename a function to describe what it does
It doesn't align anything -- any allocations are already aligned to
whatever multiple is required -- it just shrinks the allocated space.
2016-12-18 10:30:35 +01:00
Benno Schulenberg 1144d38316 tweaks: don't bother reallocating a string of which there is only one
And which normally is just some ten or twenty characters long, and
never gets wildly overallocated.

Benno Schulenberg 0562d27b9c tweaks: delete a bunch of unneeded asserts
Nano would crash straight afterward if any of these asserts would fail,
so they don't add anything.  A few others are simply superfluous.

Benno Schulenberg c5f49167ea tweaks: write two pieces of conditionalized code like all others

Benno Schulenberg 9765c2faa0 tweaks: elide a function that is called just once 2016-12-15 19:28:43 +01:00
Benno Schulenberg 85ebe971e2 chars: optimize for the most common case
That is: elide a second test from the most travelled path: a valid
character.  This adds a second call of mblen() when parse_mbchar()
is called on a terminating zero, but that should never happen.

Benno Schulenberg d6cc2c40fe tweaks: conditionalize a function that is not used in the tiny version
The fsfromline() function is mostly used by the undo functions, which
are not present in the tiny version.  It is also used by the comment/
uncomment feature, but this feature cannot be enabled when --enable-tiny
is in effect.

Benno Schulenberg b0b24d9c3a utils: slightly speed up the calculation of the size of a buffer
Achieve this by eliding two conditions from the inner loop,
which is possible because 'end' will never be NULL.

David Lawrence Ramsey c9f743f676 tweaks: elide two unneeded variables from line numbering mode

David Lawrence Ramsey bd920b1f49 tweaks: adjust the type of two arguments
Convert digits() to take a ssize_t instead of an int, since it's
used on ssize_t line numbers.  And properly use the long modifier
when displaying a line number.

Also, conditionalize the digits() prototype.

Benno Schulenberg 13ec5d8ce9 spelling: correctly restore the selected region
An added magic linefeed should be removed again /before/ restoring
the x position, as the latter needs to be calculated from the real
last line of the region.

This fixes https://savannah.gnu.org/bugs/?49817.

Benno Schulenberg 30591c5e01 tweaks: use a while loop when the end point is not known in advance
It is easier to see the order of steps and what the terminating
condition is.

Benno Schulenberg 3f8e30efb1 tweaks: delete some obscuring debugging stuff
When wanting to debug something, it is far more useful
to temporarily insert lines like:

    statusline(ALERT, "name = %i", variable);

It provides instant feedback, and it slows things down,
so you can kind of see what happens.

Benno Schulenberg e9fde7d7dc mouse: use the correct screen width for calculating the cursor position
When there are line numbers, the effective available screen width is
smaller than COLS: editwincols.

This fixes https://savannah.gnu.org/bugs/?49821.

Benno Schulenberg fd3423f79a syntax: give the statistics part of a git patch a different color
Also, be more selective when coloring a git diff line.  And color
