    Nix Output Monitor

    Nix Output Monitor

    Pipe your nix-build output through the nix-output-monitor

    nix-output-monitor (also known as nom) is a workflow tool that enhances the readability and usability of nix-build output by providing pretty, parsed summaries and highlighting important events during Nix builds. This was an experiment to write something fun and useful in Haskell, which proved to be useful to quite a lot of people. By now, nom is quite fully featured with support for nix v1 commands (e.g. nix-build) and nix v2 commands (e.g. nix build). At this point it seems like I will maintain nom until better UX options for nix arrive. Every entry in the nom tree stands for one derivation. No build will be printed twice in the tree, it will only be shown for the lowermost dependency. Use the colors from above to read the summary.

    Agda

    Agda

    Agda is a dependently typed programming language

    Agda is a dependently typed, total functional programming language and interactive theorem prover based on Martin-Löf’s type theory. It allows expressing programs and proofs in the same language, using the Curry–Howard correspondence. It features interactive development via Emacs, Atom, or VS Code. Agda is a dependently typed functional programming language. It has inductive families, i.e., data types which depend on values, such as the type of vectors of a given length. It also has parametrised modules, mixfix operators, Unicode characters, and an interactive Emacs interface which can assist the programmer in writing the program. Agda is a proof assistant. It is an interactive system for writing and checking proofs. Agda is based on intuitionistic type theory, a foundational system for constructive mathematics developed by the Swedish logician Per Martin-Löf. It has many similarities with other proof assistants based on dependent types, such as Coq, Epigram, Matita and NuPRL.

    relude

    relude

    Safe, performant, user-friendly and lightweight Haskell library

    relude is a safe, performant, user-friendly and lightweight Haskell standard library. The default Prelude is not perfect and doesn’t always satisfy one’s needs. At this stage, you may want to try an alternative prelude library. relude has some strong goals and principles that it sticks to. That principles define the library's decisions and might tell you more about the priorities of the library. You can be more productive with a “non-standard” standard library, and relude helps you with writing safer and more efficient code faster. Usage of partial functions can lead to unexpected bugs and runtime exceptions in pure code. The types of partial functions lie about their behaviour. And even if it is not always possible to rely only on total functions, relude strives to encourage best-practices and reduce the chances of introducing a bug.

    The Futhark Programming Language

    The Futhark Programming Language

    A data-parallel functional programming language

    Futhark is a small programming language designed to be compiled into efficient parallel code. It is a statically typed, data-parallel, and purely functional array language in the ML family, and comes with a heavily optimizing ahead-of-time compiler that presently generates either GPU code via CUDA and OpenCL, or multi-threaded CPU code. Futhark is not designed for graphics programming, but can instead use the compute power of the GPU to accelerate data-parallel array computations. The language supports regular nested data-parallelism, as well as a form of imperative-style in-place modification of arrays, while still preserving the purity of the language via the use of a uniqueness type system. While the Futhark language and compiler is an ongoing research project, it is quite usable for real programming and can compile nontrivial programs which then run on real machines at high speed.

    Unison

    Unison

    A friendly programming language from the future

    Unison is an open source functional programming language based on a simple idea with big implications: code is content-addressed and immutable. Unison’s core idea is that code is immutable and identified by its content. This lets us reimagine many aspects of how a programming language works. We simplify codebase management, Unison has no builds, no dependency conflicts, and renaming things is trivial. The same core idea forms the basis for a runtime that robustly supports dynamic code deployment, allowing a single Unison program to describe entire elastic distributed systems. Though a lot of the work on Unison is still experimental and ongoing, we’re sharing an early alpha release of the language for you to test out. We’ll make a more finished release generally available soon. In the meantime, anyone is welcome to help with alpha testing.

    Beam

    Beam

    A type-safe, non-TH Haskell SQL library and ORM

    Beam is a Haskell interface to relational databases. Beam uses the Haskell type system to verify that queries are type-safe before sending them to the database server. Queries are written in a straightforward, natural monadic syntax. Combinators are provided for all standard SQL92 features, and a significant subset of SQL99, SQL2003, and SQL2008 features. Beam is standards-compliant but not naive. We recognize that different database backends provide different guarantees, syntaxes, and advantages. To reflect this, Beam maintains a modular design. While the core package provides standard functionality, Beam is split up into a variety of backends which provide a means to interface Beam's data query and update DSLs with particular RDBMS backends. Backends can be written and maintained independently of this repository. For example, the beam-MySQL and beam-firebird backends are packaged independently.

    erd

    Translates a plain text description of a relational database schema

    erd is a Haskell-based command-line tool that transforms a plain-text description of a relational database schema into a graphical entity-relationship diagram using common ER conventions. This utility takes a plain text description of entities, their attributes and the relationships between entities and produces a visual diagram modeling the description. The visualization is produced by using Dot with GraphViz. There are limited options for specifying color and font information. Also, erd can output graphs in a variety of formats, including but not limited to: pdf, svg, eps, png, jpg, plain text and dot. In case one wishes to have a statically linked erd as a result, this is possible to have by executing build-static_by-nix.sh: which requires the nix package manager to be installed on the building machine. NixOS itself is not a requirement.

    Kitten

    Kitten

    A statically typed concatenative systems programming language

    Kitten is an experimental, concatenative programming language that blends Forth/Joy-style stack programming with modern static typing and effect tracking. Programs are composed by chaining small words that transform a typed stack, and the compiler uses type inference to ensure compositions are valid. The language explores disciplined handling of side effects, aiming to separate pure transformations from operations that perform I/O or mutate state. Its design encourages small, reusable building blocks that compose cleanly, while still permitting low-level control where performance matters. The implementation targets efficient compiled code and investigates how advanced type systems can improve reliability in a stack-based language. As a research project, Kitten serves both as a language to experiment with and as a vehicle for ideas about safety and structure in concatenative programming.

    Paperboy

    Paperboy

    a small .pdf management tool with a command-line UI

    Paperboy is a tiny .pdf management utility. If you download papers and other pdf documents, you might have noticed that filenames like 1412.4880.pdf are not terribly helpful for finding anything later on. This tool helps with that. It will offer to rename and move files to a specified folder, and it even gives some filename suggestions by looking at the content and the pdf metadata. Paperboy keeps its file management dumb on purpose (no keeping files in a database or hidden library folder), so you can uninstall it at any time and your files will remain perfectly accessible. Any pointers or help with regards to generate .deb, .rpm, AUR PKGBUILD, etc is appreciated. Ideally this could be mostly automated in CI, in the end Paperboy is just a single binary with a dependency or two. How do other packages do it? If you got a good example or link, open a GitHub issue! Make sure you have poppler installed, which will provide both pdftotext and pdfinfo.

    Semantic

    Parsing, analyzing, and comparing source code across many languages

    semantic is a Haskell library and command line tool for parsing, analyzing, and comparing source code. Run semantic --help for complete list of up-to-date options. Semantic uses tree-sitter to generate parse trees, but layers in a more generalized notion of syntax terms across all supported programming languages. We'll see why this is important when we get to diffs and program analysis, but for now let's just inspect some output. It helps to have a simple program to parse. Symbols are named identifiers driven by the ASTs. This is the format that github.com uses to generate code navigation information allowing c-tags style lookup of symbolic names for fast, incremental navigation in all the supported languages. The incremental part is important because files change often so we want to be able to parse just what's changed and not have to analyze the entire project again.
