This will break all plugins which currently use Win.viewport.

vis{,-std}.lua:
* replace removed _TOKENSTYLES with _TAGS
* don't add default styles to the lexer. lexers no longer
define their own styles
filetype.lua: update path detection for scintillua 6.2
|
|
The old style handling had a lot edge cases where one of the
colours or the attribute wouldn't get applied correctly. This
commit adds a new style_set() method to the Ui which should be
called instead of manually touching a cell's style. This also
means that the Cell struct can be made opaque since all the
handling is now done inside the ui-terminal files.
With this it is now viable to combine the light and dark 16 colour
themes into a single base-16 theme. This theme works very well
with the Linux virtual console and will now be the default theme
regardless of if the terminal supports 256 colours or not. This
should address the common complaints about vis not respecting the
users default terminal colours.
fixes #1151: Theming is sometimes partially applied or ignored
see #1103: terminal no longer has transparency/opacity
see #1040: Transparent background and setting options by default

This hasn't worked in almost a year and even if it did it makes no
sense. Based on my testing lexing takes a couple milliseconds at
most. If it took 1 second (the default value for this option) vis
would be completely unusable.
If people want support for this it should be submitted upstream
and vis will act based on the outcome of that.

fixes #1119: lua: lpeg module isn't actually optional

- Resync the lexers with Scintillua
- Update the lexer readme
- Update `zenburn` theme to fix some highlighting issues
- lexers: redirect print function to vis:info()
- Fix support for custom style names
- As per error message "lexer.delimited_range() is deprecated, use lexer.range()".
- Remove remaining `lexer.delimited_range()` call
- Set syntax to `nil` if the file type has no matching lexer
- Updated Go lexer for Go 1.18.
- lexers/dsv: convert to new lexer format
(cherry picked from commit 9edbc3cd9ea1d7142b1305840432a3d2739e755a)
- lexers/gemini: disable legacy gemini lexer
This reverts commit 468f9ee1b027a7ce98b1a249fa1af5888feeb989.
It is in legacy format and of questionable quality. Ideally it
should be contributed upstream from where it will eventually
trickle down to us.
- lexers/git-rebase: convert to new lexer format
(cherry picked from commit 4000a4cc9ac4a4c2869dfae772b977a82aee8d8c)

- lexers/typescript: add new upstream lexer revision 28e2b60
(cherry picked from commit 7326e6deecdaa75fa94ae9ebdb653f9f907b33f2)
- use `package.searchpath` instead of a local `searchpath` function
- Restore `filetype: support filetype detection via hashbang`
- Remove redundant comment
- Restore gemini lexer

Upper bound lexing time and cancel highlighting if it is exceeded.

barely noticeable CPU usage improvement, although the number of
iterations went down by an order of magnitude.

Fix #695
|
|
The color settings are currently stored in the `vis.lexers` table,
make sure it is not nil even when loading the lexer module (or one
of its dependencies e.g. lpeg) failed.
|
|
|
|
Use something like dos2unix(1) and unix2dos(1), if you
need to edit such files.
|
|
I think the default value for the cache argument to the lexer load
function should be true, not false. Optimize for the common case.
This makes the API ugly/harder to use. But for now we follow upstream.

It is no longer possible to change the used syntax by assigning to the
`win.syntax = name` field, instead the function win:set_syntax(name)`
should be called.
The distinction between filetype and syntax lexer to use should probably
be clarified/cleaned up at some point.

Use pull instead of push based model for display code. Previously view.c
was calling into the ui frontend code, with the new scheme this switches
around: the necessary data is fetched by the ui as necessary.
The UI independent display code is moved out of view.c/ui-curses.c into
vis.c. The cell styles are now directly embedded into the Cell struct.
New UI styles are introduced for:
- status bar (focused / non-focused)
- info message
- window separator
- EOF symbol
You will have to update your color themes.
The terminal output code is further abstracted into a generic ui-terminal.c
part which keeps track of the whole in-memory cell matrix and #includes
ui-terminal-curses.c for the actual terminal output. This architecture
currently assumes that there are no overlapping windows. It will also
allow non-curses based terminal user interfaces.

The file name completion does not yet behave the same way as
the previous C code because the completion prefix is currently
simply calculated using the `iw` text object which does not
handle common path elements (e.g. `.`, `/`, `~`, etc).
|
|
It remains to be seen whether that is a good idea, but at least
it will reveal possible bugs.
|
|
Based on a patch by Denis Warsow.
Stuff which could probably be improved:
- in vim the cursor does not need to be on top of the number,
it suffices to be on the same line.
- decrementing beyond zero does not work for hexadecimal and
octal numbers, vim seems to wrap around in this case.
0x00000000 <C-x> becomes 0xffffffff

Load a standard plugins directly from vis-std.lua.
|

Terminal.app sets $TERM=xterm-256color and ships a corresponding
terminfo description advocating that it is capable of color changes
to the 256 color palette when in fact it can not.
We introduce a new boolean option "change-256colors" which is
true by default but can be used to disable color changes. It is
automatically set if Terminal.app is detected using $TERM_PROGRAM.
This should fix display artifacts as described in #456.

Hook it up via Lua to <C-k> in insert and replace mode.
Close #460 #475
|
|
|
|
Differentiate between the case where the module is not found and
the case where an error occured while loading it.
This should make it easier to debug cases in which there is a
Lua version mismatch between vis and lpeg.

Close #429

|
The init event is emitted immediately after `visrc.lua` has been sourced, but
before any other events have occured, in particular the command line arguments
have not yet been processed.
Close #422
|
|
The editor core calls into the functions registered in the `vis.events`
table which then multiplex the events to all registered event handlers.
The first handler which returns a non `nil` value terminates event
propagation.
|
|
The following structure is adapted:
* visrc.lua entry point for all Lua code
* vis.lua only implements the Lua part of the core API
* vis-std.lua registers standard event handlers (e.g. syntax highlighting,
statusbar handling, theme changes etc). It is sourced from vis.lua.
* plugins/* non essential editor functionality, needs to be explicitly
enabled by loading it from visrc.lua
