EasyPeasy - Auto Layout made easy

Swift

In this quick tour through EasyPeasy we assume that you already know the advantages and disadvantages of the different Auto Layout APIs and therefore you won't see here a comparison of the code side by side, just read and decide whether EasyPeasy is for you or not. The example below is quite simple but shows how effortless its implementation result using EasyPeasy.

WebCola - Javascript constraint-based graph layout

TypeScript

JavaScript constraint based layout for high-quality graph visualization and exploration using D3.js and other web-based graphics libraries. Note: While D3 adaptor supports both D3 v3 and D3 v4, WebCoLa's interface is styled like D3 v3. Follow the setup in our homepage for more details.

MyLinearLayout - MyLayout is a powerful iOS UI framework implemented by Objective-C

Objective-C

Is equivalent to: UIStackView of iOS and LinearLayout of Android. Linear layout is a single line layout view that the subviews are arranged in sequence according to the added order（from top to bottom or from left to right). So the subviews' origin&size constraints are established by the added order. Subviews arranged in top-to-bottom order is called vertical linear layout view, and the subviews arranged in left-to-right order is called horizontal linear layout.

TangramKit - TangramKit is a powerful iOS UI framework implemented by Swift

Swift

TGLayoutPos is represent to the position of a view. UIView provides six extension variables:tg_left, tg_top, tg_bottom, tg_right, tg_centerX, tg_centerY to set view's margin or space distance between self and others. TGLayoutSize is represent to the size of a view. UIView provides two extension variables:tg_width,tg_height to set view's width and height dimension. there are three special TGLayoutSize const object: .wrap, .fill, .average mean: wrap all subviews size, fill in to superview's residual size, average the superview's size.

dry-types - Flexible type system for Ruby with coercions and constraints

Ruby

After checking out the repo, run bin/setup to install dependencies. Then, run bundle exec rake run_specs to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment. To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

rein - Database constraints made easy for ActiveRecord.

Ruby

Data integrity is a good thing. Constraining the values allowed by your application at the database-level, rather than at the application-level, is a more robust way of ensuring your data stays sane. Unfortunately, ActiveRecord doesn't encourage (or even allow) you to use database integrity without resorting to hand-crafted SQL. Rein (pronounced "rain") adds a handful of methods to your ActiveRecord migrations so that you can easily tame the data in your database.

the-power-of-prolog - Introduction to modern Prolog

HTML

Prolog is a programming language that is rooted in formal logic. It supports backtracking and unification as built-in features. Prolog allows us to elegantly solve many tasks with short and general programs. The goal of this material is to bridge the gap between the great traditional Prolog textbooks of the past and the language as it currently is, several decades after these books were written. You will see that many limitations of the past are no longer relevant, while several new constructs are now of great importance even though they are not yet covered in any available Prolog book.

gophersat - gophersat, a SAT solver in Go

This is Gophersat, a SAT and pseudo-boolean solver written purely in Go. Gophersat was developed by the CRIL (Centre de Recherche en Informatique de Lens) at the Artois University & CNRS. It is released under the MIT license. Gophersat is rather efficient, i.e on typical SAT benchmarks it runs about 2 to 5 times slower than top-level solvers (namely, glucose or minisat) from which it is strongly inspired. It can also solve MAXSAT problems, and pseudo-boolean decision and optimization problems. Gophersat's last stable version is version 1.1. It includes a new, more efficient core solver for pure SAT problems and a package for dealing with MAXSAT problems. It also includes a new API for optimization and model counting, where new models are written to channels as soon as they are found.

semver - Work with Semantic Versions in Go

If there is an error the version wasn't parseable. The version object has methods to get the parts of the version, compare it to other versions, convert the version back into a string, and get the original string. For more details please see the documentation.Checking a version against version constraints is one of the most featureful parts of the package.

mv-core - Migration Validators project core classes

Ruby

Project Migration Validators (MV) makes it possible for RoR developer to define validations directly in db and then bubble them up to model so they available as normal ActiveModel::Validations there. And all that without code duplication. WARNING Versions lower than 2.0 are not supported anymore. As results, rails v.3 or older are not supported either.

mv-postgresql - Postgresql constraints in migrations similiar to ActiveRecord validations

Ruby

Define validations directly in DB as PostgreSQL constraints and integrate them into your model transparently. See mv-core for details. There you will be able to review high level project information. Below you can see details of the migration validations that are supported by PostgreSQL driver.
