Previously, these could have crashed alacritty. Now, they simply print
an error message in Red to stderr. The Red format wrapper was moved to a
central location where both main.rs and the alacritty lib can access it.

Resolves #22.
|
|
This allows consumers of the font crate to handle errors instead of the
library panicking.
|
|
This cleans up and fixes the C-type wrapping for fontconfig.
|
|
There's now a proper wrapper in place for working with the FontConfig
library. This should help significantly with error handling with font
loading; at least, the FontConfig code shouldn't panic. The FreeType
rasterizer still needs to be updated to handle missing fonts, and a more
sensible default font should be specified.
|
|
Also adds a benchmark for cell.reset().
|
|
Just a bit of cleanup.

There was a lot of complexity around the threadsafe `Flag` type and
waking up the event loop. The idea was to prevent unnecessary calls to
the glutin window's wakeup_event_loop() method which can be expensive.
This complexity made it difficult to get synchronization between the pty
reader and the render thread correct. Now, the `dirty` flag on the
terminal is also used to prevent spurious wakeups. It is only changed
when the mutex is held, so race conditions associated with that flag
shouldn't happen.
|
|
Moving the window on macOS would cause a panic in certain circumstances.
|
|
|
|
Using underscores because it's easy. It's also wrong.
cc #11
|
|
The terminal mutex is no longer released between event processing and
doing a draw. This may fix the race condition with data arriving but not
being displayed until a subsequent event.
cc #29
|
|
|
|
Searching on the ref tests would find matches in the terminal recording
files and completely screw up the screen state.
|
|
Long lines were previously broken at the terminal width. Now, a wrapping
marker is kept on the final cell so that extra newlines are not
inserted.
|
|
|
|
The reloaded config was not used immediately.
|
|
Still need automatic loading into selection copy buffer for linux.
|
|
The somewhat redundant KeyBinding and MouseBinding types were removed in
favor of a Binding<T> type. This allows all binding code to be reused
for both scenarios.
The binding tests were fixed by only asserting on `is_triggered_by()`
instead of checking that the action escape sequence was delivered
properly.
|
|
The event handling code grew organically over time, and with that came a
number of warts. The primary issue was with passing some random
selection of arguments to the input::Processor based on what the input
was. There was the issue that if multiple events were drained from a
single PollEventsIterator, the terminal mutex was potentially locked and
unlocked many times. Finally, and perhaps most importantly, there was no
good way to pass necessary state to the Action executor without going
through several API layers.
To fix all that, the input::ActionContext and input::Processor are now
generated once per call to the event::Processor. The input::Processor
holds onto the ActionContext so that it doesn't need to be passed
through layers of function calls. When a binding is activated, the
ActionContext is simply passed to the handler.
This did have the effect of breaking the input::Processor tests
(specifically, those relating to bindings). The issue was not addressed
in this commit since a larger refactor of the bindings is planned which
should also improve testability.
|
|
Various functions take some permutation of the current selection, the
terminal, and a notifier. Instead of having to juggle some number of
arguments everywhere, the `ActionContext` is constructed and then passed
around.
|
|
Only works with strings, currently.
|
|
This adds the ability to click and drag with the mouse and have the
effect of visually selecting text. The ability to copy the selection
into a clipboard buffer is not yet implemented.
|
|
The main refactor broke config reloading; specifically, colors were not
updating for subsequent draws.

All of the changes in this commit are due to clippy lints.

Resolves #25
|
|
This adds a trait OnResize and a separate method handle_resize to the
display. Instead of having a callback to receive resize events, a list
of &mut OnResize are passed to this new method. Doing this allowed the
only RefCell usage in the codebase to be removed :).
|
|
|
|
The cell under the cursor is now tracked in the input processor at
`self.mouse.line` and `self.mouse.column`. This could probably be
optimized to only compute the cell when in certain states, but the
calculation is cheap.
|
|
|
|
This makes scrolling work for mouse wheels (was previously just
trackpads).
|
|
* config::Monitor is more ergonomic and self-contained
* Fixed an issue with macOS resize. Previously, the terminal was marked
as dirty in the window resize handler, but the display can't do that.
Instead, the event processor returns a flag whether it was requested
to wakeup.
|
|
This is part of an ongoing decoupling effort across the codebase and
tidying effort in main.rs. Everything to do with showing the window with
a grid of characters is now managed by the `Display` type. It owns the
window, the font rasterizer, and the renderer. The only info needed from
it are dimensions of characters and the window itself for sizing the
terminal properly. Additionally, the I/O loop has access to wake it up
when new data arrives.

The doc comment outlines my plan about cleaning up this function.

Adds a wrapper for the glutin::Window which provides strongly typed
APIs and more convenient interfaces. Moves some gl calls into the
opengl-based renderer.
The point of most of the changes here is to clean up main().
|
|
This cleans up the Config::load API significantly. Several miscellaneous
comments were also added.
|
|
This introduces the `cli` module and the `cli::Options` type. This type
holds all the options passable on the command line in addition to
providing arg parsing.
|
|
|
|
The identify_terminal function signature had to change to support
writing to the terminal before processing additional input.
|
|
|
|
glutin::Window is not threadsafe; putting it into an Arc is
misleading (although the glutin::Window type claims to be Send + Sync).
The reference was just needed on the main thread anyway, so it's better
to just pass a ref around directly.
|
|
There's now a ColorList type that provides strongly typed indexing for
not only usize but NamedColor as well. Previously, the `NamedColor` was
casted to a `usize` when indexing the colors. Additionally, only one
copy of the ColorList needs to exist;it's borrowed from the `Config`
when rendering, and the renderer doesn't need a copy.
