In TreeView:on_mouse_pressed() we need to find the directory a
relative filename belongs to from its absolute filename.
The code was using string.find to locate the relative filename
within the absolute path but in some very specific cases we can
find a pattern which is not the right-most one leading to a
wrong directory name.
Fix the error by adding a loop to make sure we find the right-most
match. The standard Lua library has not a string.rfind to make a
reverse search.
Add a check to avoid trying to updating a topdir project directory.
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?
In order to stay simple and closer to the lite's design principles we
deprecate the core.add_save_hook function and the related mechanism.
Instead we now directly override the Doc:save() method.
The method is already overrided from core.init to add the automatic
reloading of style when user's module is saved.
The cleanup is related to the discussion in issue #229.
The bug was actually due to a presence of a ghost tab scrolling button
in all the views.
We need to check if the node has multiple views, if not there are no tabs
and therefore no scrolling button areas so we return nothing from the
method Node:get_scroll_button_index().
Close#216
When the number of files in a project directory is above the max
limit switch back to a mechanism to read directory content only
when the corresponding folder is expanded in the treeview.
When the command core:find-file is invoked the command core:open-file
is executed instead because the complete list of the project's
files is not available.
When a project search is done we search through all the files within
the project dir without indexing them.
Address issues #217#203#183.
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.
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.
This is the way was supposed to be. All the filenames are supposed to be
stored without home encoding, i.e. with explicit paths.
Should fix issue #177 and make PR
https://github.com/franko/lite-xl/pull/174
unneeded.
It may also address issue #174 but would need further verifications.
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.
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).
