Adds support for 'normal' and 'focus' Style Boxes to Terminal node.
Changes default background color to transparent, with background to be
set by StyleBox.
If background color is not transparent, will draw a background color
rect to cover the entire control over the top of any stylebox. This is
consistent with the behavior of the TextEdit node with regards to theme
colors and styleboxes.
- Primary example scenes (menu, terminal, and asciicast) working but
still a lot of warning/error messages and some regressions.
- Editor integrated terminal works, but still a lot of warning/error
messages and some regressions.
- Added support for "blink" display attribute.
- Removed GDScript terminal code. Terminal node is now purely a
GDExtension. So is LibuvUtils.
- GUT tests not working yet.
- Still a lot of things to fix.
- So far, only built for and manually tested on Linux x86_64.
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.
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.
Temporary measure until we can resolve the issue where inactive tabs
would be closed when clicking on the area where the close button will
show when policy was CLOSE_BUTTON_SHOW_ACTIVE_ONLY.
Clearing the terminal removes all lines in the scrollback buffer except
for the most recent.
With sb_reset, the terminal will return the scrollback buffer to the
bottom when the user starts typing if they have previously scrolled up.
- Add TerminalSettings resource.
- Init/load terminal settings from terminal panel.
- Add terminal context menu (i.e. right-click PopupMenu).
- Add shortcut to open a new terminal Ctrl+Shift+T and make terminal panel
visible.
In order to use the gdnative library as an editor plugin it was
neccessary to set the `reloadable` property of the gdnlib file to false,
in order to prevent crashes when the godot editor window lost focus.
This may have consequences when recompiling the library.
See: https://docs.godotengine.org/en/3.3/classes/class_gdnativelibrary.html#class-gdnativelibrary-property-reloadable
Still crashes quite frequently and doesn't close child processes
properly.
Part of #43.
