This package provides an Elm library for working with POSIX times, time zones, formatting, and the clock.

Elm is a statically-typed, purely-functional programming language for the browser. The elm exectable includes commands for developers such as elm make and elm repl.

This package allows you to create Elm programs that run in browsers, with access to browser history for SPAs.

This package provides extra functions for working with Posix times from elm/time.

Make SVG charts in all Elm. The package can draw charts at a variety of different levels of customization, from basic charts with standard features to very custom styles. The library also allows including your very own SVG elements while still easily utilizing the coordinate system calculated from your data, as well as editing the SVGs made by the package. It has great support for interactivity, layering different charts, and adding irregular details.

This library converts a Float to a String with ultimate control how many digits after the decimal point are shown and how the remaining digits are rounded. It rounds, floors and ceils the common way (i.e. half up) or the commerical way (ie. half away from zero).

This package provides a virtual DOM implementation that backs Elm's core libraries for HTML and SVG. You should almost certainly use those higher-level libraries directly.

This package helps you convert between Elm values and JSON values.

This package provides a version of the Elm compiler without support for the elm reactor development command.

This package enables writing unit and fuzz tests for Elm code. To actually run the tests, you need the command-line tool from https://github.com/rtfeldman/node-test-runner, which has not yet been packaged for Guix.

This package helps you:

1. build new URLs; and

2. parse existing URLs into nice Elm data structures.

Use it for HTTP and for routing in SPAs.

Emacs Lisp Mock is a library for mocking and stubbing using readable syntax. Most commonly Emacs Lisp Mock is used in conjunction with Emacs Lisp Expectations, but it can be used in other contexts.

This package provides a modern list API library for Emacs.

Eldev (Elisp Development Tool) is an Emacs-based build tool, targeted solely at Elisp projects. It is an alternative to Cask. Unlike Cask, Eldev itself is fully written in Elisp and its configuration files are also Elisp programs. For those familiar with the Java world, Cask can be seen as a parallel to Maven — it uses project description, while Eldev is sort of a parallel to Gradle — its configuration is a program on its own.

This package provides a Makefile to help checking Emacs packages.

This package provides a Makefile-like script and a transient menu for linting and testing Emacs packages.

Espuds is a collection of the most commonly used step definitions for testing with the Ecukes framework.

To allow for the usage of Emacs functions and macros that are defined in newer versions of Emacs, compat.el provides definitions that are installed ONLY if necessary. These reimplementations of functions and macros are at least subsets of the actual implementations. Be sure to read the documentation string to make sure.

Not every function provided in newer versions of Emacs is provided here. Some depend on new features from the core, others cannot be implemented to a meaningful degree. The main audience for this library are not regular users, but package maintainers. Therefore commands and user options are usually not implemented here.

emacs-ansi defines functions that turns simple strings to ANSI strings. Turning a string into an ANSI string can be to add color to a text, add color in the background of a text or adding a style, such as bold, underscore or italic.

Buttercup is a behavior-driven development framework for testing Emacs Lisp code. It groups related tests so they can share common set-up and tear-down code, and allows the programmer to "spy" on functions to ensure they are called with the right arguments during testing.

This provides a list of issues with the Emacs package metadata of a file, e.g., the package dependencies it requires. Checks will currently be enabled only if a Package-Requires: or Package-Version: header is present in the file.

This package allows ERT to work with asynchronous tests.

emacs-ert-expectations is a simple unit test framework for Emacs Lisp to be used with ert.

This package provides an Emacs library for manipulating strings.
