Elixir Companies
A list of companies currently using Elixir in production
elixir-companies is a community-maintained directory of organizations that use Elixir in production. It serves both as a discovery tool for developers curious about who is adopting the language and as a hiring signal for companies wishing to reach the Elixir community. The site categorizes entries by region, industry, and hiring status, making it easy to browse or filter by interests and location. Contributions are handled publicly via pull requests, with maintainers reviewing updates to ensure accuracy and consistency. Beyond simple listings, the project highlights the breadth of Elixir usage—from startups to large enterprises—and helps newcomers see real-world adoption. The codebase itself is an example Phoenix application, offering a transparent, collaborative model for community content. Over time, the directory has become a reference point frequently cited when assessing Elixir’s ecosystem health and job market. -

Embedded Firmware Library
Library for typical microcontroller- and peripheral functions
Embedded developers always use their favorite controllers, and if you want to modify open source code, you often have to dive deep in the datasheet of that controller. The "Embedded Firmware Library" is a project which offers a kind of API to control the controller-functions and the functions of the peripheral units on a certain board. As an application developer, you don't have to know anything about the registers of the controller. And you can write controller- and board-independent code. In principle, another developer can use your code without modifications on his board and with his favorite controller. -

Embedded Template Library (ETL)
Embedded Template Library
C++ is a great language to use for embedded applications and templates are a powerful aspect. The standard library can offer a great deal of well-tested functionality, but there are some parts of the standard library that do not fit well with deterministic behavior and limited resource requirements. These limitations usually preclude the use of dynamically allocated memory and containers with open-ended sizes. What is needed is a template library where the user can declare the size, or maximum size of any object upfront. Most embedded compilers do not currently support the standard beyond C++ 03, therefore excluding the programmer from using the enhanced features of the later library. -

Emoji
A library to add Emoji support to your Android / JVM Application
A Kotlin Multiplatform library to add Emoji support to your Android App / JVM Backend. Check out the sample jvm module for text parsing/searching functionality. PopupWindow which overlays over the soft keyboard. Normal view which is used by EmojiPopup and can also be used as a standalone to select emojis via categories. The library has 4 different sprites providers to choose from (iOS, Google, Facebook & Twitter). The emoji's are packaged as pictures and loaded at runtime. If you want to use a Font provider, check out Google Compat. For convenience, there's also a EmojiLayoutFactory, which can be used to get automatic Emoji support when using normal Android Views such as TextView, Checkbox, etc. -

Emoji for Python
emoji terminal output for Python
Emoji for Python. This project was inspired by kyokomi. The entire set of Emoji codes as defined by the Unicode consortium is supported in addition to a bunch of aliases. By default, only the official list is enabled but doing emoji.emojize(language='alias') enables both the full list and aliases. By default, the language is English (language='en') but also supported languages are Spanish ('es'), Portuguese ('pt'), Italian ('it'), French ('fr'), German ('de'). The utils/get-codes-from-unicode-consortium.py may help when updating unicode_codes.py but is not guaranteed to work. Generally speaking it scrapes a table on the Unicode Consortium's website with BeautifulSoup and prints the contents to stdout in a more useful format. -

Emoji-Log
An Emoji Git commit log messages spec standard
After building hundreds of open source software I've ended up inventing a git commit log standard called EMOJI-LOG that helps me understand a project's history with a less cognitive load just by looking at the git log. I like emoji. I like ’em a lot. Programming, code, geeks/nerds, open-source, all of that is inherently dull and sometimes boring. Emoji (which is, in fact, the plural of emoji) helps me add colors and emotions to the mix. Nothing wrong if you want to attach feelings to this 2D flat text-based world of code. I found out that instead of memorizing hundreds of emoji it's better to keep the categories small and general. -

EmojiPackage
A collection of expression pack resources, Zhang Zhang is a classic
Project address: Github , Code Cloud. Programmer's first emoji, you deserve it. The expression pack is used well, you don't need to find a girlfriend. Knowing the answer: What are some emojis that make you happy in a second? In this impetuous society, using words to communicate is often unsatisfactory, so now we prefer to use emoticons to vividly express our words at this moment. However, the expression packs will be more and more accumulated over time. At this time, it is very troublesome to find the expression pack. At this time, you need this sorted expression pack. More than 2,000 expression packs, if you find the expression pack you need, you can directly search for keywords. Strongly recommend this project as a Git version management project to enjoy permanent updates. -

Encode_LV
LabVIEW VIs for ZLib compression and Base64/binhex encoding
These VIs use C-based DLL access to ZLib (https://zlib.net/) and ASCII encode/decode. The VIs and development files are included in this package. You are most likely to be running this from a Windows machine which means that loading the LabVIEW code will generate an error. This is due to the LabVIEW code pointing to the Linux SO instead of the DLL. To fix it, double-click on the CLFN VIs and browse to DLL. -

End-To-End
End-To-End is a crypto library to encrypt, decrypt, digital sign
End-to-End was a client-side encryption project that prototyped OpenPGP-compatible, end-to-end encrypted messaging in the browser. The idea was to move cryptographic operations entirely to the user’s machine—key generation, encryption, and signature—so messages remain unreadable to intermediaries. It packaged a JavaScript crypto library, UI elements, and a browser extension workflow that could integrate with webmail-style UIs without server changes. The codebase emphasized careful key handling, usability experiments around key discovery and verification, and mitigations against common web threats like XSS. While the project ultimately transitioned into successor efforts, it helped push discussions about practical E2EE in mainstream web apps and the ergonomics of PGP-style workflows. Security researchers and product teams used it as a design reference for client-side cryptography and the trade-offs of operating inside a hostile web page. -

Enlive
Selector-based templating and transformation system for Clojure
Enlive is a Clojure library for HTML templating, transformation, and scraping, supporting composable manipulation of HTML/XML in a functional style. It allows selecting, transforming, and generating HTML fragments using CSS selectors, and supports server-side template composition, dynamic pages, and content rewriting. By default selector-transformation pairs are run sequentially. When you know that several transformations are independent, you can now specify (as an optimization) to process them in lockstep. Note that this doesn't work with fragments selectors. Transformations are now slightly restricted in their return values: a node or a collection of nodes (instead of freely nested collections of nodes). -

EnterAccess
Full JAVA JDBC Interface to MS Access using Jackcess
This JDBC interface serves as a full JAVA interface to MS Access files. It was developed to support the Software-Independent Archival of Relational Databases (SIARD) of the Swiss Federal Institute. It is based on the project Jackcess for accessing MS Access files and makes use of the project H2 for parsing SQL. It is an alternative to the JDBC interface UCanAccess, whose metadata and type support and very limited SQL for DDL and DML queries could not be adapted for the purposes of SIARD. Currently EnterAccess queries are limited to a single table. All DML and DDL queries are limited by the capabilities of Jackcess, which is good at reading a database and weak on creating a view, creating foreign keys, or modifying a schema. -
