brick
brick
is a Haskell terminal user interface programming library in the
style of gloss. This means
you write a function that describes how your user interface should look,
but the library takes care of a lot of the book-keeping that so commonly
goes into writing such programs.
brick
exposes a declarative API. Unlike most GUI toolkits which
require you to write a long and tedious sequence of "create a widget,
now bind an event handler", brick
just requires you to describe your
interface using a set of declarative combinators. Then you provide a
function to transform your application state when input or other kinds
of events arrive.
Under the hood, this library builds upon
vty, so some knowledge of Vty
will be helpful in using this library.
This library deprecates vty-ui.
Example
Here's an example interface (see programs/ReadmeDemo.hs
):
withBorderStyle unicode $
borderWithLabel (str "Hello!") $
(center (str "Left") <+> vBorder <+> center (str "Right"))
Result:
┌─────────Hello!─────────┐
│ │ │
│ │ │
│ Left │ Right │
│ │ │
│ │ │
└────────────────────────┘
Featured Projects
To get an idea of what some people have done with brick
, take a look
at these projects:
Getting Started
TLDR:
$ cabal sandbox init
$ cabal install -j -f demos
$ .cabal-sandbox/bin/brick-???-demo
To get started, see the user guide.
Documentation
Documentation for brick
comes in a variety of forms:
Feature Overview
brick
comes with a bunch of widget types to get you started:
- Vertical and horizontal box layout widgets
- Basic single- and multi-line text editor widgets
- List widget
- Progress bar widget
- Simple dialog box widget
- Border-drawing widgets (put borders around or in between things)
- Generic scrollable viewports
- Extensible widget-building API
- User-customizable attribute themes
- (And many more general-purpose layout control combinators)
In addition, some of brick
's more powerful features may not be obvious
right away:
- All widgets can be arranged in predictable layouts so you don't have
to worry about terminal resizes.
- Attribute management is flexible and can be customized at runtime on
a per-widget basis.
Brick-Users Discussion
The brick-users
Google Group / e-mail list is a place to discuss
library changes, give feedback, and ask questions. You can subscribe at:
[https://groups.google.com/group/brick-users](https://groups.google.com/group/brick-users)
Status
There are some places were I have deliberately chosen to worry about
performance later for the sake of spending more time on the design (and
to wait on performance issues to arise first). brick
is also something
of an experimental project of mine and some aspects of the design
involve trade-offs that may are not entirely settled. In addition you
can expect this library to follow a principle of fearless improvement:
new versions will make (sometimes substantial) API changes if those
changes really do make the library better. I will place more importance
on getting the API right than on maintaining backwards compatibility.
brick
exports an extension API that makes it possible to make your own
packages and widgets. If you use that, you'll also be helping to test
whether the exported interface is usable and complete!
Reporting bugs
Please file bug reports as GitHub issues. For best results:
-
Include the versions of relevant software packages: your terminal
emulator, brick
, ghc
, and vty
will be the most important
ones.
-
Clearly describe the behavior you expected ...
-
... and include a minimal demonstration program that exhibits the
behavior you actually observed.
Contributing
If you decide to contribute, that's great! Here are some guidelines you
should consider to make submitting patches easier for all concerned:
- If you want to take on big things, talk to me first; let's have a
design/vision discussion before you start coding. Create a GitHub
issue and we can use that as the place to hash things out.
- Please make changes consistent with the conventions I've used in the
codebase.
- Please adjust or provide Haddock and/or user guide documentation
relevant to any changes you make.
