Francesco Abbate 1cf0f2009c Add a C API copy method for font_desc objects
Add a renderer.font's method "copy" to clone the font object
by specifying an optional new size. In the size is not given
the size of the original object is used.

Should fulfill the request from issue #288.

Francesco Abbate 752ecd5ece Group mouse move events from C API function
Groups together consecutive mouse move events like done in core.step()
lua function but on the C side.

It does not introduce any meaningful speedup but it theory is more efficient and
simplifies the Lua code.

The simplification of the Lua code alone is enough to justify this change?

Scale fonts context menu (#246)
* Retrieve scale plugin from lite-plugins

* New implementation of scale plugin and font C API

Introduce two new C API functions, renderer.font.get_size and set_size
respectively to get the font size and to set the size to a new value.

Using these functions we don't need to know the name of the font but
we can just change their size.

Adapt the scale plugin to use the new C API function with minor adaptations
in the logic.

Use smaller step to scale fonts.

Rename font_desc_free function, previous name was misleading as only the cached
resources are freed.

* Add contextmenu plugin from takase

From https://github.com/takase1121/lite-contextmenu

Adapted to show font scaling commands and find/replace commands.

i#	testing.lua

* Fix the cursor flickering with contextmenu

To avoid flickering of the cursor when using the context menu
we add a new function `core.request_cursor` that just take note
of the cursor requested.

The cursor will be actually changed only in root_view:draw() method
only when all the drawing operations are done. This means the cursor
will be changed only once per frame and only the most recent cursor
change request will take effect.

* Remove unneeded scale plugin return functions

Flush the SDL_QUIT event when Cmd+W is detected in SDL_KEYDOWN as well (#248)
On macos 11.2.3 with sdl 2.0.14 the keyup handler for cmd+w was not
enough. Maybe the quit event started to be triggered from the keydown
handler? In any case, flushing the quit event there too helped.

Enable lite-xl to be started from a symlink to the deployed binary (#249)
Use resolved executablePath instead of resourcePath to allow lanching
the lite-xl binary via a symlink, like typically done by Homebrew:

/usr/local/bin/lite-xl -> /Applications/lite-xl.app/Contents/MacOS/lite-xl

The resourcePath returns /usr/local in this case instead of
/Applications/lite-xl.app/Contents/Resources, which makes later
access to the resource files fail. Resolving the symlink to the
executable and then the relative path to the expected directory
Resources is a workaround for starting the application from both
the launcher directly and the command line via the symlink.

Francesco Abbate aa0b2bb5fc Fix crash problem with rencache and font access
In some cases rencache was using a FontDesc pointer that was actually freed by
Lua giving segfaults errors.

In addition, some FontDesc object were not freed in some cases if the
rencache_end_frame was not called when performing the "restart" command.

The invalid access problem can happen because rencache keep some pointers to
FontDesc object but these are Lua userdata that Lua can dispose of. This
situation is prone to hard errors and we should avoid to keep pointers to
objects managed by Lua.

To this purpose we use luaL_ref/unref to bind the FontDesc into the Lua's
registry while rencache need them. We still keeps pointer to FontDesc object but
using luaL_ref we are assured they will not be disposed by Lua.

Since we are using luaL_ref/unref to inform the GC about when the objects are in
use we can now finalize the objects directly when Lua collects them. Previously
the GC metamethods was issuing a FREE command to rencache and the font was
actually freed only from the rencache_end_frame function.

Allowed for optional boolean to better match filenames. (#180) 2021-05-16 19:23:17 +02:00
Francesco Abbate 4c99a18341 More accurate update rects / show window / present sequence
For the option when we use the SDL_Renderer we change:

- the order of calls to SDL_DestroyTexture/Renderer.
  Reported by valgrind on linux as an error to destroy the
  renderer before the texture.
- the SDL_Renderer and texture are created when the surface is
  initialized before the window is shown

It seems that creating the SDL_Renderer and Texture between the
moment the window was shown and the renderer present was introducing
a flashing blank window because of the time taken to create the
renderer/texture resources.

Francesco Abbate 46c3bdea67 First implementation of scaling for retina display
Introduce a new approach that discriminate coordinates in
points and pixels. Now all the logic from the Lua side and in
rencache is to always use points. The coordinates are converted
to pixels only within the renderer, in the file renderer.c.
In this way the application logic does not need to care about the
scaling of the retina displays.

For non-retina display the scaling between points and pixels is
equal to one so nothing will change.

There is nevertheless a change that leak into the Lua side. The
subpixel coordinates are in sub-pixel, not sub-points so they are
scaled by the retina scaling factor. But no change in the code is
required because the subpixel scaling factor take into account the
retina scaling, when present.

Because the retina scaling factor is not know when the application
starts but only when a window is actually available we introduce a
mechanism to render the font with a given scaling factor only from
the renderer when they are needed. We use therefore FontDesc to
describe the font information but without actually rasterizing the
font at a given scale.

Francesco Abbate c97fa9a3a6 Fix bug with wrong hashing of rencache commands
The command in rencache.c (Command struct + variable length text) was
incorrectly sized. As a result some bites at the end of the command payload
were uninitialized and was causing hash to randomly change forcing the
system to redraw many more areas.

Since the text of the command for DRAW_TEXT commands is written beginning
at the offset of the text field we compute the bare size of the command as
offsetof(Command, text) instead of sizeof(Command).

Francesco Abbate 3426bc5d73 Introduce subpixel text positioning within rencache
In order to fix the issue with cursor positioning a subpixel-aware draw
text operation within rencache was required.

consecutive, inline, text drawings with subpixel accuracy.

Francesco Abbate 9ff6a0325e Mostly fix problem of offset with cursor positioning when using mouse
In order to get right the cursor position on text on mouse clicks it is
needed to take into account text's subpixel positioning.

This fix mostly corrects the problem but cursor positioning is still
somewhat inaccurate for long lines due to repeated commands to draw a text
along a line. Repeated draw text calls make the subpixel information
lost and small errors will add-up.

Francesco Abbate 35f31c8fbc Fix font rendering artifacts bug
Seen with some fonts like FiraSans, github issue:

https://github.com/franko/lite-xl/issues/46

The fix works essentially by looking to the bounds of each glyph to
accurately ensure that there are no overlaps between the glyphs.

The construction of the font atlas was changed to make some related
improvements now that the bounds of each glyph are know. The main
changes are:

- no longer align glyph on the baseline but align them on their upper
  bounds. We ensure this way that very tall fonts do not leak in the
  upper part
- terminate the row based on x bounds of the glyph to be more accurate
- for each row keep trace of the y of the more larger along y of the
  glyph. The value is used to start a new row to be sure that the new
  now does not overlap with the previous one
- sort glyphs by y size before drawing them. In this way the space
  utilization is better. The algorithm used is the very simple insert
  sort. It behaves like O(n^2) with the number of characters but should
  be ok since n is always small, typically below 128.
- compute the optimal image width and height for the given font's atlas
  for optimal memory usage. As a bonus now the lite's code don't have to
  try and repeat to get a good image size

The problem was that when the editor had no events the cursor was not

Now we no longer calls wait_event without a timeout if the windows has
the focus. When the window has the focus the timeout is set to 1 / fps
so that the cursor can blinks.

In addition we react to the "focus lost" event to ensure the documents
are redrawn without the cursor.
