This feature is on by default
|
|
The architecture here is really poor. Need to move file watching into a
dedicated location and probably have an spmc broadcast queue. other
modules besides rendering will care about config reloading in the
future.
|
|
This is used by things like Bash's reverse-i-search and things get
*very* messed up without it.
|
|
Also enables debug symbols in release profile by default. Until
Alacritty ships, there's going to be lots of perf analysis which needs
debug symbols.
The PriorityMutex low priority method was never used. Now it's just a
fair mutex.
|
|
|
|
This was previously logging as an unhandled `execute`.
|
|
Using the vte crate allows removal of the ansi parser state machine and
enables us to just be concerned with actions described in the protocol.
In addition to making alacritty simpler, this also improves correctness
and performance.
|
|
|
|
Errors/warnings fixed.
|
|
It was always printing intead of only debug builds.
|
|
Switched to vendored Utf8Chars.
|
|
Escapes terminated by a bell were not properly handled.
|
|
Previous version of serde no longer worked; cargo packages were updated
as a result. `Zero` and `One` traits were deprecated. Use of those was
removed. The `Step` trait gained a lot more methods, and the index::$ty
implementations were updated.
|
|
|
|
Nothing uses it yet, but it is tracked in the terminal state.
|
|
The line/column were swapped. Strong types are great, but we still have
to be careful at the lowest level before they take effect!
|
|
ansi::Handler methods dealing with lines or columns now accept a `Line`
or `Column` where appropriate instead of ambiguous `i64`.
|
|
DebugHandler was a helper during initial development of the parser. It's
not used any longer.
|
|
The rows function has been renamed to lines, and it now returns `Line`.
The cols function correspondingly returns `Column`.
|
|
Configuration may now be specified in either `$HOME/.alacritty.yml` or
`$HOME/.config/alacritty.yml`. See `alacritty.yml` in the repository
root for an example.
When a configuration file cannot be located, a default configuration is
used.
|
|
|
|
The sense of set_mode and unset_mode was inverted. The
TextCursor/ShowCursor mode depended on the incorrect behavior, and that
was fixed as well. TextCursor was renamed to ShowCursor to be perfectly
clear on the intent.
|
|
|
|
There's never a count associated with this, and it has been removed from
the Handler method to reflect as much.
|
|
Of note are the `ansi` and `grid` modules becoming public. There are
several bits of unused code in each of these. In the case of `grid`, the
unused parts are generally useful, like some indexing implementations.
In ansi, there are pieces that will be used once the parser is more
complete. In any case, these modules are fairly generic and mostly
usable outside of Alacritty.
Unused cargo packages were also removed.

It's now possible to move around within Vim without the screen becoming
corrupt!
The ANSI parser now calls a (new) `set_scrolling_region` on the handler
when the DECSTBM CSI is received. In order to provide a sensible default
in case that the sequence doesn't include arguments, a TermInfo trait
was added which currently has methods for inspecting number of rows and
columns. This was added as an additional trait instead of being included
on Handler since they have semantically different purposes. The tests
had to be updated to account for the additional trait bounds.
The utilities module now has a `Rotate` trait which is implemented for
the built-in slice type. This means that slices and anything derefing to
a slice can be rotated. Since VecDeque doesn't support slicing (it's
a circular buffer), the grid rows are now held in a Vec to support
rotation.
For ergomomic access to the grid for scrolling and clearing regions,
additional Index/IndexMut implementations were added to the grid::Row
type.
Finally, a `reset` method was added to `Cell` which properly resets the
state to default (instead of just clearing the char). This supports
region clearing and also fixed a bug where cell backgrounds would remain
after being cleared.

There were several unrecognized escape codes that have arguments which
were being interpretted as input. Naturally, this caused state to be
corrupt. The escape codes are now handled by throwing away the bytes.
Consider this a TODO for later.
|
|
Properly handles goto_col and goto_row. Additionally, input wrapping is
handled.
Truecolor specs are now set appropriately.
|

This patch introduces basic support for terminal emulation. Basic means
commands that don't use paging and are not full screen applications like
vim or tmux. Some paging applications are working properly, such as as
`git log`. Other pagers work reasonably well as long as the help menu is
not accessed.
There is now a central Rgb color type which is shared by the renderer,
terminal emulation, and the pty parser.
The parser no longer owns a Handler. Instead, a mutable reference to a
Handler is provided whenever advancing the parser. This resolved some
potential ownership issues (eg parser owning the `Term` type would've
been unworkable).

This is the initial terminal stream parsing implementation for
Alacritty. There are currently several TODOs, FIXMEs, and unimplemented!
things scattered about still, but what's here is good enough to
correctly parse my zsh startup.
The `Parser` implementation is largely based on the suck-less _simple
terminal_ parser. Because this is Rust and Rust has a fantastic type
system, some improvements are possible. First, `Parser` is a struct, and
its data is stored internally instead of statically. Second, there's no
terminal updates hard-coded into the parser. Instead, `Parser` is
generic over a `Handler` type which has methods for all of the actions
supported by the parser. Because Parser is generic, it should be
possible (with proper inlining) to have equivalent performance to the
hard-coded version.
In addition to using _simple terminal_ as a reference, there's a doc in
Alacritty's repository `docs/ansicode.txt`, a summary of the ANSI
terminal protocol, which has been referenced extensively.
There's probably a large number escapes we don't handle, and that's ok.
There's a lot that aren't necessary for everyday terminal usage. If you
feel like something that's not supported should be, feel free to add it.
Please try not to become overzealous and adding support for sequences
only used by folks trapped in 1988.
