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

emacs-community-random-extra includes lots of extra helper functions for the Random module.

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

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

Undercover is a test coverage library for software written in Emacs Lisp.

This package provides a Makefile to help checking Emacs packages.

This package provides Ecukes, a Cucumber-inspired integration testing tool for Emacs. Ecukes is not a complete clone of Cucumber and is not intended to be.

This package provides an Emacs library for working with files and directories.

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.

This package silences most output of Emacs when running an Emacs shell script.

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.

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.

ert-runner is a tool for Emacs projects tested using ERT. It assumes a certain test structure setup and can therefore make running tests easier.

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

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 provides a modern list API library for Emacs.

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 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 an Emacs library for manipulating strings.

emacs-commander provides command line parsing for Emacs.

Emacs Typit is a typing game for Emacs. Words that are picked randomly from the most frequent words in language you're practicing, until time is up.
