m-2k/erlach

Erlach is an anonymous imageboard and comments service built on the Erlang ecosystem. It provides core imageboard functionality including user authentication, post management, and a single-page application interface. The system also integrates a full-text search engine with BM25 scoring and tools for converting video screenshots into optimized image formats.

Introduced a new full-text search application for Erlang, including the core engine, BM25 scoring, database schema, and Porter stemmer for text processing. Additionally, added a shell script to convert MOV files to optimized GIFs and PNGs to AVIFs, along with a .gitignore for the screenshots directory.

The repository is initialized with the core configuration and build infrastructure for Erlach, a single-page application imageboard. This includes the Erlang dependency manifest (rebar.config) specifying libraries such as N2O, Cowboy, and Mnesia, alongside build scripts (Makefile, otp.mk) and configuration files (sys.config, vm.args) that define the application's runtime environment, ports, and cookie settings.

(repo-wide) · high confidence

A new Rebar3 configuration file (rebar.config) has been added to the apps directory. This file defines the subdirectories to be included in the build (eauth, ecod, erlach, erlach\_db, fulltext\_search, kvs\_feeds, and spa), sets the library directory to the parent apps folder, and specifies the dependencies directory. This change establishes the build structure for these specific applications within the larger project.

Added the eauth library, a simple email-based authorization system for web applications, providing sign-in, activation, join, and password reset functionality with configurable SMTP and hashing settings. Simultaneously, added the erlach imageboard application, including its core headers, utility modules, and static assets (CSS, JavaScript, HTML templates, and SVG icons) to support the user interface and client-side logic.

m-2k/erlach was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.
