Benno Schulenberg 2428c5cbe6 tweaks: strip a parameter that is equivalent to 'openfile' for both calls 2020-03-08 12:54:47 +01:00
Benno Schulenberg 01bc0148c0 tweaks: strip a parameter that is TRUE for both calls
The parameter has been redundant since version 4.0, commit d54840c1,
when the last call with FALSE was removed.

Benno Schulenberg 622111613f tweaks: elide two variables and their two assignments
Also reshuffle two declarations, and confine the swapping of
the endpoints of a backward-marked region to a smaller scope.

Benno Schulenberg 21ef05058c tweaks: add a COUPLE_END undo item a bit later, instead of updating it 2020-03-06 12:30:24 +01:00
Benno Schulenberg abcdd6605c tweaks: reshuffle a condition, for compacter code 2020-03-05 19:37:09 +01:00
Benno Schulenberg f2d89cb3bc justify: restore a region properly when it was marked backwards
This fixes https://savannah.gnu.org/bugs/?57960.

Bug existed since version 4.8, commit e01651cd.
2020-03-05 18:46:37 +01:00
Benno Schulenberg 2d05ce37c6 justify: do not crash when the user attempts to justify an empty region
This fixes https://savannah.gnu.org/bugs/?57959.

Bug existed since version 4.0, since the justifying
of a marked region was introduced.

Benno Schulenberg 2bc5c1987c tweaks: factor out a three-line condition into a separate function
For clarity.

Benno Schulenberg e39e2ddf52 tweaks: add a supporting variable, in order to condense some statements 2020-03-05 16:07:52 +01:00
Benno Schulenberg ac61254581 tweaks: invert the logic of a symbol, to make more sense
Giving a name to the uncommon case is more fitting.

It also avoids a negation and allows to elide a condition.

Benno Schulenberg 9e182fde66 tweaks: swap the use of 'head' and 'tail' for CUT and PASTE undo items
Now the 'head' endpoint is closer to the top of the buffer, and the
'tail' endpoint closer to the bottom.  That makes more sense.

Benno Schulenberg 70d59ffe16 tweaks: remove a redundant assignment
Consecutive additions all happen on the same line.  When automatic
hard-wrapping occurs, the ADD item is grouped together with an ENTER
item, and subsequent additions go into a new ADD item.

Benno Schulenberg fb4bcd8cfd undo: store the cursor row, for redoing filtering & justification better
This fixes https://savannah.gnu.org/bugs/?57958.

Benno Schulenberg 2288abcd49 tweaks: use the variable that suits 'END' better 2020-03-05 12:34:17 +01:00

Benno Schulenberg d675a549de rcfile: don't store a coloring rule before it is complete
This really fixes https://savannah.gnu.org/bugs/?57950.

Benno Schulenberg 6bab8d19c6 tweaks: adjust the indentation after the previous change
And regroup things a bit.
2020-03-03 19:46:46 +01:00
Benno Schulenberg 365058c48f rcfile: when a start= is not matched with an end=, abandon the whole rule
This fixes https://savannah.gnu.org/bugs/?57950.

Bug existed since before version 2.2.0.
2020-03-03 19:42:40 +01:00
Benno Schulenberg 5eb7145939 rcfile: do not allow a regex for name, header, or magic to be empty
If the user really wants to match anything, ".*" should be used.

(This also stops nano looking at the rest of the line as soon as an
empty regular expression is encountered.  This may seem like poorer
feedback than before, but... I think that multiple error messages
per line are more confusing than helpful.)

This fixes https://savannah.gnu.org/bugs/?57942.

Bug existed since before version 2.2.0.

Benno Schulenberg 9f92341c84 tweaks: check for a starting quote in one place instead of three 2020-03-03 16:31:28 +01:00
Benno Schulenberg 3357712928 tweaks: remove two superfluous conditions
The 'ptr' variable can never be NULL in those places -- whenever it
becomes NULL, the routine returns immediately.

Benno Schulenberg 0e59c12af4 tweaks: rename a function, and split a variable into two separate ones 2020-03-03 11:27:37 +01:00
Benno Schulenberg aab0d43f47 tweaks: rename a function, to be more fitting, and improve some comments 2020-03-03 11:16:51 +01:00
Benno Schulenberg 9cc32c920b rcfile: when finding a mistake, skip the rest of the line 2020-03-03 10:55:23 +01:00
Benno Schulenberg 72ad00f9d0 tweaks: change an integer to a short, and reshuffle it for better packing
A short allows for more than 32 thousand values, and the maximum number
of multiline regexes in any of the current syntaxes is... just four.

Reshuffle it to the beginning also because it is used the most often.

Benno Schulenberg 89217f20af tweaks: rename two symbols, to be more precise 2020-03-02 17:16:07 +01:00
Benno Schulenberg 477a9b33b4 files: when piping, always pipe whatever was cut to the external command
Either the marked region was cut (even when zero characters) or
the entire contents of the buffer were cut.  In both cases this
is what needs to be piped to the command.  That is: the contents
of the cutbuffer.

This fixes https://savannah.gnu.org/bugs/?57931.

Bug existed since version 2.9.8, commit f304b9ae,
when piping text to an external command was introduced.

Benno Schulenberg 6c34ae5804 files: don't check uninitialized memory when writing new file [valgrind]
This fixes https://savannah.gnu.org/bugs/?57934.

Bug existed since version 4.3, commit e8e30e51.

Benno Schulenberg 4409b275fc tweaks: avoid a complaint about uninitialized memory [valgrind]

Benno Schulenberg 8848ac5a9b undo: do not try to copy a cutbuffer that is NULL
Allow the creation of an empty CUT undo item (because the result of a
filtering operation may be empty), but then don't crash when undoing
such an empty CUT.

This fixes https://savannah.gnu.org/bugs/?57929.

Bug existed since version 2.9.8, when filtering was introduced.

Benno Schulenberg c055e629c7 tweaks: copy and store a deleted character in a conciser manner 2020-02-28 19:24:31 +01:00
Benno Schulenberg e6f26464d7 tweaks: add calls of die() for five theoretical programming mistakes 2020-02-28 19:15:23 +01:00
Benno Schulenberg a0aeeba075 tweaks: remove two redundant case labels
The add_undo() and update_undo() functions are never called with
JOIN as argument, so there is no need to have a case label for it.
2020-02-28 19:05:09 +01:00
Benno Schulenberg c640a55b1c tweaks: frob a statement, rewrap two lines, and remove a pair of braces 2020-02-28 18:59:04 +01:00
Benno Schulenberg 7d0b7e47c1 undo: use the correct original fusion point when unjoining two lines
When a <Backspace> did the join, 'head' and 'tail' are not the same.

This fixes https://savannah.gnu.org/bugs/?57916.

Bug existed since commit 7cf08b93 from yesterday.
2020-02-28 17:09:03 +01:00
Benno Schulenberg 132ed5c8f0 tweaks: instead of swapping the end points later, assign them correctly
(This also makes it clear that the naming of 'head' and 'tail'
is the wrong way around for CUT too.)
2020-02-28 15:25:23 +01:00
Benno Schulenberg bd88b8b5a6 undo: do not mark the buffer as modified when pasting back nothing
This completes the fix for https://savannah.gnu.org/bugs/?57915.
2020-02-28 13:40:35 +01:00
Benno Schulenberg 0568f7a2b6 undo: do not try to paste back an empty cutbuffer
Trying to do so would dereference a NULL pointer in copy_node().

This fixes https://savannah.gnu.org/bugs/?57915.

Bug existed since before version 2.2.0.
2020-02-28 13:40:06 +01:00
Benno Schulenberg 1a28b08694 tweaks: frob two statements, condense another, and add a comment
Also, remove two superfluous closings of file descriptors.  The second
one has most likely already been closed by send_data(), by closing the
tube, and the first one will be closed by exiting from the process.
2020-02-28 12:41:27 +01:00
Benno Schulenberg 3b3a6b12a7 tweaks: remove two superfluous checks
The single check when creating any CUT undo item is enough.
2020-02-28 10:28:23 +01:00
Benno Schulenberg 50213eee81 tweaks: reorder a case item, to have SPLIT_BEGIN always before SPLIT_END
Also, avoid two superfluous assignments of a message, as they get
overwritten immediately by other ones, and later with the same.

Furthermore, remove two pointless placements of the cursor.  Any
necessary placements are handled by the actual adding of data and
the breaking of lines in the ADD and ENTER items.

Benno Schulenberg 7cd2a7da7c tweaks: remove a superfluous assignment, and reshuffle a call 2020-02-27 15:09:36 +01:00
Benno Schulenberg 4f67f364bc tweaks: when undoing an addition or redoing a deletion, do not reallocate
Especially when undoing an addition, reallocating the line data is a
waste of time, because most likely other text will be added instead.

(This also removes a coding error in the redo code for a deletion:
it allocated too many bytes for the new line data: twice the amount
of the deletion too much.)
2020-02-27 14:16:49 +01:00
Benno Schulenberg 7cf08b93ff tweaks: don't bother reallocating the line data when undoing a line join 2020-02-27 13:51:56 +01:00
