Blessed v0.1.0 - new terminal goodies for node.js
The features demonstrated in the above gif element transparency/shadow and border docking.
New useful options for your typewriter application:
-
transparent
option - Lower element opacity to 50%. This will display dimmed elements and content behind the foreground element using a naive color blending function (good enough for a terminal's limited amount of colors). works best with 256color terminals. (see widget-shadow.js) -
shadow
option - Give the element a translucent shadow. Automatically darkens the background behind it. (see widget-shadow.js) -
dockBorders
option - Element borders will automatically "dock" to each other. Instead of overlapping the borders end up connecting. (see widget-dock.js) -
autoPadding
default - Auto padding is now enabled by default, meaning blessed will automatically position elements inside their parent's border. -
rleft
property - Relative offsets are now default element properties (left
instead ofrleft
). -
draggable
property - Make any element draggable with the mouse. (see widget-shadow.js or widget-dock.js) -
Table
andListTable
elements - Tables with a high quality rendering. (see widget-table.js and widget-listtable.js) -
Log
element - A top to bottom logger box with scrollback and other features. (see widget-log.js) -
Obscurable borders - In addition to docking borders, it's possible to obscure borders by sliding them off the screen with negative offsets. (see widget-dock.js)
-
Percentage expressions - Like CSS, arithmetic can now be performed on percentages. e.g.
width: '50%-1'
. This is useful for overlapping borders on elements with a percentage width. (see widget-dock.js)
Other features that weren't mentioned before:
-
setHover
option - Set a hover text box to follow cursor on mouseover, similar to how a web browser handles the "title" attribute. (see widget.js) -
Terminal
element - Spin up a pseudo terminal as a blessed element. useful for writing a terminal multiplexer. (requires term.js and pty.js as optional dependencies). (see example/multiplex.js) -
Image
element - Usesw3mimgdisplay
to draw real images your terminal. this is much easier than calling w3mimgdisplay by hand. Image elements behave like any other element, although it is wise to usewidth: 'shrink', height: 'shrink'
. (see widget-image.js)
The major things that justified the 0.1.0 release were fixes and stabilization
of api (autoPadding
/rleft
/left
). Scrolling boxes were almost completely
revamped to work a bit smarter.
Things yet to come:
-
@secrettriangle's improvements for textareas - This allows for real text navigation.
-
Gravity and margin layouts
This is something that's been in the idea bin for a while. Every element could potentially have properties like:
gravity: 'bottomleft',
margin: 5,
``
In other words, just a more complex `float` system than what the CSSOM is used
to.
