nicm 49ec074271 Tidy up new UTF-8 code and make it more generic. 2020-05-25 18:19:29 +00:00
nicm bbfb44e9b2 Make some data types consistent. 2020-05-25 15:02:25 +00:00
nicm 3a5219c6d0 Instead of storing all UTF-8 characters in the extended cell which means
that 14 bytes are wasted for each character in the BMP, only store
characters of three bytes or less in the cell itself and store others
(outside the BMP or with combining characters) in a separate global
tree. Can reduce grid memory use for heavy Unicode users by around 30%.

nicm 1ebd8c1234 Add p format modifier for padding to width. 2019-11-25 15:04:15 +00:00
nicm e90d4a6021 Add formats for word and line under the mouse and use them to add some
items to the pane menu.

nicm f006116bac Environment variables can start with { also. 2019-05-23 18:22:13 +00:00
nicm 27bfb56ad5 Break the argument escaping code into a separate function and use it to
escape key bindings in list-keys. Also escape ~ and ; and $ properly.

nicm 979313832c Extend the #[] style syntax and use that together with previous format
changes to allow the status line to be entirely configured with a single
option.

Now that it is possible to configure their content, enable the existing
code that lets the status line be multiple lines in height. The status
option can now take a value of 2, 3, 4 or 5 (as well as the previous on
or off) to configure more than one line. The new status-format array
option configures the format of each line, the default just references
the existing status-* options, although some of the more obscure status
options may be eliminated in time.

Additions to the #[] syntax are: "align" to specify alignment (left,
centre, right), "list" for the window list and "range" to configure
ranges of text for the mouse bindings.

The "align" keyword can also be used to specify alignment of entries in
tree mode and the pane status lines.

nicm 467ece53e6 Remove unused variable. 2017-06-04 09:02:57 +00:00
nicm 8149bc3fa6 Be more strict about escape sequences that rename windows or set titles:
ignore any that not valid UTF-8 outright, and for good measure pass the
result through our UTF-8-aware vis(3).

nicm 248aa54bfd Style and spacing nits. 2017-05-31 17:56:48 +00:00
nicm 67d2335130 Fix a couple of argument types. 2017-03-17 14:51:41 +00:00
nicm faa0570309 Plain stravis() because it will mangle UTF-8 characters, so add
utf8_stravis() which calls our existing utf8_strvis() and use it instead
2017-01-18 10:08:05 +00:00
nicm 8b804fb589 Support UTF-8 entry into the command prompt. 2016-10-11 07:11:40 +00:00
nicm 9892d80d6f Most of the utf8_data is fixed so simplify utf8_set to use a memcpy. 2016-05-27 22:57:27 +00:00
nicm 7abdfbe20e OpenBSD wcwidth() is sensible and complete so if it returns -1 it means
that a character is not printable, so return to ignoring such
characters.
2016-04-29 09:11:19 +00:00
nicm 23fdbc9ea6 Loads of platforms appear to have old or broken Unicode character type
information and are missing widths for relatively common Unicode
characters (so mbtowc() works, but wcwidth() fails). So if wcwidth()
returns -1, assume a width of 1 instead of ignoring the character.
2016-04-27 09:36:25 +00:00
nicm d303e55258 Log wcwidth() and mbtowc() failure to make it easier to debug a Unicode
codepoint not appearing.
2016-04-26 07:33:36 +00:00
nicm b8a102d26f Handle wcwidth() and mbtowc() failures in better style and drop
characters where we can't find the width (wcwidth() fails) on input, the
same as we drop invalid UTF-8. Suggested by schwarze@.
2016-03-02 15:36:02 +00:00
nicm 26945d7956 Use system wcwidth() instead of carrying around UTF-8 width tables. 2016-03-01 12:02:08 +00:00
nicm fa64b89ad7 Whoops, need this for the previous reverse trim commit too. 2016-01-31 09:57:41 +00:00
nicm 995af0e2b7 I no longer use my SourceForge address so replace it. 2016-01-19 15:59:12 +00:00
nicm 933929cd62 Memory leaks and an uninitialized part of utf8_data, from Patrick Palka. 2015-11-20 22:02:54 +00:00
nicm 3db0d50df4 The private use area at U+E000 to U+F8FF is not very useful if it is
width 0, make it width 1 instead.
2015-11-14 12:03:23 +00:00
nicm 205d15e82d All these return values from utf8_* are confusing, use an enum. 2015-11-14 11:45:43 +00:00
nicm f401791a56 Rename a variable in utf8_combine for consistency and use 0xfffd for
unknown Unicode.
2015-11-14 11:13:44 +00:00
nicm 64333e3ef8 Be more strict about invalid UTF-8. 2015-11-14 10:56:31 +00:00
nicm c5689a5a40 Long overdue change to the way we store cells in the grid: now, instead
of storing a full grid_cell with UTF-8 data and everything, store a new
type grid_cell_entry. This can either be the cell itself (for ASCII
cells), or an offset into an extended array (per line) for UTF-8
data.

This avoid a large (8 byte) overhead on non-UTF-8 cells (by far the
majority for most users) without the complexity of the shadow array we
had before. Grid memory without any UTF-8 is about half.

The disadvantage that cells can no longer be modified in place and need
to be copied out of the grid and back but it turned out to be lot less
complicated than I expected.

nicm e71a915412 Rename overly-long utf8data to ud throughout. 2015-11-12 22:04:37 +00:00
nicm a209ea3953 Add utf8_padcstr and use it to align columns in list-keys. 2015-11-12 12:43:36 +00:00
nicm d6daf37df4 Tidy utf8.c a little: build table on first use, and make utf8_width take
a u_int rather than splitting and then combining again in utf8_split.
2015-11-12 12:19:57 +00:00
nicm c41673f3fa If we know the terminal outside tmux is not UTF-8, replace UTF-8 in
error messages and whatnot with underscores the same as we do when we
draw UTF-8 characters as part of the screen.
2015-11-12 11:10:50 +00:00
nicm 69e0b8326a Support UTF-8 key bindings by expanding the key type from int to
uint64_t and converting UTF-8 to Unicode on input and the reverse on
output. (This allows key bindings, there are still omissions - the
largest being that the various prompts do not accept UTF-8.)
2015-11-12 11:05:34 +00:00
schwarze e9b58d9de4 Update the internal wcwidth(3) table of tmux(1) to match the data
in /usr/src/share/locale/ctype/en_US.UTF-8.src, with one single
exception:  Keep U+00AD SOFT HYPHEN at width 1 rather than moving
it to width 0, a tradition already observed in the old
https://www.cl.cam.ac.uk/~mgk25/ucs/wcwidth.c .
While here, manually rebalance the btree for optimal lookup speed.

nicm 806520f025 Add some UTF-8 utility functions and use them to prevent the width limit
on formats from splitting UTF-8 characters improperly.

nicm a5d4b7f3d9 Some more long lines. 2014-04-17 14:45:49 +00:00
nicm 252a7373d6 Support UTF-8 with choose-buffer, from Kosuke ASAMI. Also make
buffer_sample bigger to let it trim at window right edge.
2014-04-02 18:12:18 +00:00
nicm ee19d304ff In four byte UTF-8 sequences, only three bits of the first byte should
be used. Fix from Koga Osamu.

Nicholas Marriott 27dcf470dc Remove some Korean characters from the zero-width list that apparently
shouldn't be there, from Jeong Mok Cho.
2013-04-12 12:50:36 +00:00
Nicholas Marriott ac3b78a841 Support for UTF-8 mouse input (\033[1005h). This was added in xterm 262
and supports larger terminals than the older way.

If the new mouse-utf8 option is on, UTF-8 mouse input is enabled for all
UTF-8 terminals. The option defaults to on if LANG etc are set in the
same manner as the utf8 option.

With help and based on code from hsim at gmx.li.

Nicholas Marriott 9afb0d739e %zu not %u, doh. 2009-10-20 22:17:33 +00:00
Nicholas Marriott 1af09d6330 Try to reduce the UTF-8 mess.
Get rid of passing around u_char[4]s and define a struct utf8_data which has
character data, size (sequence length) and width. Move UTF-8 character
collection into two functions utf8_open/utf8_append in utf8.c which fill in
this struct and use these functions from input.c and the various functions in
screen-write.c.

Space for rather more data than is necessary for one UTF-8 sequence is in the
utf8_data struct because screen_write_copy is still nasty and needs to reinject
the character (after combining) into screen_write_cell.

Nicholas Marriott 1675ddb4d1 Miscellaneous unused functions, including one which was basically a
duplicate. Found by lint.

Nicholas Marriott 35876eaab9 Import tmux, a terminal multiplexor allowing (among other things) a single
terminal to be switched between several different windows and programs
displayed on one terminal be detached from one terminal and moved to another.
