    core.match

    core.match

    An optimized pattern matching library for Clojure

    core.match is a high-performance pattern-matching library for Clojure and ClojureScript. It provides an optimized macro-based DSL for structurally matching data—such as sequences, maps, regexes—offering a clearer alternative to nested conditionals or destructuring. A symbol pattern can represent one of three behaviours. Match the value of an existing local binding. Create a "named" wildcard pattern that creates a binding of the given name to the right of the pattern row.

    Learn Elixir

    Learn Elixir

    Learn the Elixir programming language to build functional web apps

    ...It teaches Elixir’s core types and syntax with short, runnable examples, then moves into real project work using Mix for generating apps, compiling, running tasks, managing dependencies, and creating docs. You’ll learn to write idiomatic modules and functions, use the Enum module, and practice pattern matching and the pipe operator in small, composable functions. The guide also shows how to generate API docs with ex_doc, write and run tests with ExUnit and doctest, and measure coverage—forming a complete feedback loop.

    Design Patterns for Humans

    An ultra-simplified explanation to design patterns

    Design Patterns for Humans is a developer-friendly guide that explains classic software design patterns using plain language, intuitive analogies, and succinct code examples. Instead of dense academic prose, it focuses on “why” and “when” to use a pattern, including trade-offs that help readers make pragmatic choices. The material groups patterns into categories such as creational, structural, and behavioral, mirroring common references while staying approachable for self-study. Each pattern’s section typically includes intent, real-world motivation, and an example implementation to cement understanding. ...

    Bolt for JavaScript

    Bolt for JavaScript

    A framework to build Slack apps using JavaScript

    ...To listen to messages that your app has access to receive, you can use the message() method which filters out events that aren’t of type message. message() accepts an optional pattern parameter of type string or RegExp object which filters out any messages that don’t match the pattern. A RegExp pattern can be used instead of a string for more granular matching. Within your listener function, say() is available whenever there is an associated conversation (for example, a conversation where the event or action which triggered the listener occurred). say() accepts a string to post simple messages and JSON payloads to send more complex messages. ...

    Like grep but for natural language questions

    fltr is a minimal, dependency-free filtering utility written in C, inspired by UNIX philosophy and designed for high-performance data stream filtering. It allows users to apply pattern-based rules to lines of input—much like grep or awk—but with a focus on simplicity, low overhead, and customizability. It's intended for those who need a small, efficient tool to clean, parse, or analyze large streams of textual data on the command line without complex scripting or configuration.

    Functors.jl provides tools to express a powerful design pattern for dealing with large/ nested structures, as in machine learning and optimization. For large machine learning models, it can be cumbersome or inefficient to work with parameters as one big, flat vector, and structs help manage complexity; but it is also desirable to easily operate over all parameters at once, e.g. for changing precision or applying an optimizer update step.
