Implements the copy_selection() method, which returns the selected text.
Adds a copy_on_selection property. When this property is enabled, the
selected text will automatically be copied to the primary clipboard
(Linux X11/Wayland only).
Adds additional tests for the interface. Creates a new base test class
GodotXtermTest that adds some additional assert methods. Tests
inheriting from this should override the got_described_class() method.
Add instance of the described class named 'subject' will be created and
added to the scene tree before each test.
Adds the option `use_threads` to PTY (enabled by default) which improves
performance when enabled. For example, running `time cat file.txt` where
file is ~4.5MB will take ~0.250s with threads enabled, versus >20s when
disabled.
Disconnects the "gui_input" signal as the _gui_input() override is
working as expected now. Having this signal connected was causing it to
be called twice for every input.
- Install Gut using gd-plug.
- Add some basic tests.
- Update workflow to run tests.
- Add test and gd-plug install/uninstall recipes to Justfile.
- Re-enable debug builds as these are used by editor when testing.
Changes Emscripten SDK version to match that used to compile the default export
templates used by Godot 3.5 (in this case 3.1.14 as can be seen here:
https://github.com/godotengine/build-containers/blob/3.5/Dockerfile.javascript).
This means we no longer need to compile custom export templates when
exporting HTML5 for Godot 3.5. Exports from other Godot versions may
requiring compiling the GDNative library with a different version of the
Emscripten SDK.
- Changes renderer from GLES3 -> GLES2 and reduces MSAA level to better
support HTML5 export.
- Updates GitHub Action to export HTML5 and upload as a build artifact.
- Adds Cypress test to smoke test HTML5 export.
Updates theme names to be compatible with Godot 3.5 (no spaces),
consistent with other Godot theme item names (snake_case), and
match the color names listed on the
[ANSI escape code wikipedia page](https://en.wikipedia.org/wiki/ANSI_escape_code#3-bit_and_4-bit).
Deprecates the old names and warns users to change them.
As cols and rows are read only (i.e. automatically determined by rect
and font size) there is no need for the properties to be exposed.
Instead, users can get the calculated cols and rows using the get_cols()
and get_rows() methods.
Changes `write()` method of native pipe and terminal to accept a
PoolByteArray rather than String. This means that `get_string_from_utf8()`
is no longer called on data coming from PTY and being sent to Terminal.
The terminal state machine already has a UTF8 parser which maintains
its state across calls to `write()`. This means that we can write half
the bytes of a single unicode character in one call and the remaining half
in the next call and the state machine will parse it correctly.
On the other hand, the `get_string_from_utf8()` method of Godot's
PoolByteArray requires that the array contains completely valid UTF8,
otherwise we get errors such as "Unicode error: invalid skip".
The data coming from PTY can be arbitrarily split in the middle of a
unicode character meaning that we will sometimes get errors when calling
`get_string_from_utf8()` on it. This is more likely to occur when there
is a large amount of output (i.e. it's more likely to be split). In other
cases, the data might intentionally contain invalid unicode such as when
printing binary files or random data (e.g. `cat /bin/sh`, `cat /dev/random`).
We avoid these errors by passing the PoolByteArray data directly to the terminal
state machine.
In addition to fixing unicode errors, this commit:
- Prevents repeated calls to pipes `_read_cb()` method that would block Godot
and result in a crash with the message "ERROR: All memory pool allocations
are in use" that resulted from writing data to an ever-increasing number of
PoolByteArrays before any of them could be freed. This could be triggered by
running the `cat /dev/urandom` command after making the change to `write()`
mentioned above.
- Prevents memory leaks by freeing libuv buffers after they have been copied
to PoolByteArrays.
Fixes#55.
If a PTY has a terminal_path set to a valid Terminal, then ensure that
the initial cols and rows of PTY match the cols and rows of the Terminal
when calling fork() or open(), otherwise PTY will output wrong-sized
data for the Terminal until resized.
Fixes#56.
PTY now provides a public interface to an underlying instance of
PTYNative. The PTYNative class can be extended as appropriate for
each platform and the platform-specific implementation will be
selected by PTY at runtime.
De-references pty_baton's exit callback after it is called so it can be
automatically released, preventing leaked instances.
Adds basic implementation for Pipe's get_status() method and forces PTY
to wait for child process to exit to ensure exit callback is cleaned up.
Adds a test to check that exit callback is still called as usual.
The type of winsize.ws_col and winsize.ws_row is unsigned short, so
change python's struct.unpack format from 'hh' (short) to 'HH'.
Otherwise, we can only test sizes up to 32767 when actually sizes up to
65535 are supported.
Makes for pretty paths when extending scripts:
`extends "res://addons/godot_xterm/terminal.gd"`
vs.
`extends "res://addons/godot_xterm/nodes/terminal/terminal.gd"`
Currently "res://addons/godot_xterm/pty.gd" is acutally `pty_unix.gd`.
This is okay for now as the PTY node is only supported on Unix
platforms. However, we will need to sort it out when adding Windows
support as part of #25.
Also remove the GDXterm namespace.
- Don't add the bell to the archive to keep it small a simplify
licensing. Also bells seem to be rarely used with terminal emulators.
- Don't play the bell directly from the Terminal node by adding an
AudioStreamPlayer, but make it easy to tune the "bell" signal behavior
from the Terminal node so that only an AudioStreamPlayer node's play()
method needs to be connected to it.
- Keep the bell.wav sound around for testing/demo.
- Enable tests for osx.universal platform.
- Export HTML5 (but skip upload as .cast files aren't exported
properly).
- HACK: Use HTML5 export to generate .import directory for tests
This way we don't get an error message even if using
`continue-on-error` set to `true`.
Currently tests only run on X11.64 platform.
But other platforms can be supported with a bit of effort.
Remove default bell sound as it does not play nicely with CI environment
that does not have sound card.
