 Fix: set analyticsId when registering via the Sign Up page (#256) 
registerNewUser() requires analyticsId (UserCreator throws
'bug: attributes.analyticsId is missing'), so every sign-up through the
registration-page module failed with a 500. Same fix as #208 for admin-tools.

Fixes #255

Community Edition

Overleaf is an open-source online real-time collaborative LaTeX editor. Overleaf runs a hosted version at www.overleaf.com, but you can also run your own local version, and contribute to the development of Overleaf.

Extended Community Edition (CE+)

The present "extended" version of Overleaf CE includes:

  • Sandboxed compiles with TeX Live image selection
  • Sign Up page
  • LDAP authentication
  • SAML authentication
  • OpenID Connect authentication
  • Real-time track changes and comments
  • Symbol palette
  • Template gallery
  • Import file from external URL
  • Git integration
  • GitHub synchronization
  • Zotero integration
  • Reference Search and Pick Tool
  • Document Import (.docx, .md) and Export (.docx, .md, .html)
  • Advanced administrator tools for managing user accounts and projects
  • Python script runner
  • Logo tools

Caution

Overleaf Community Edition is intended for use in environments where all users are trusted. Community Edition is not appropriate for scenarios where isolation of users is required due to Sandbox Compiles not being available. When not using Sandboxed Compiles, users have full read and write access to the sharelatex container resources (filesystem, network, environment variables) when running LaTeX compiles. Therefore, in any environment where not all users can be fully trusted, it is strongly recommended to enable the Sandboxed Compiles feature available in the Extended Community Edition.

For more information on Sandbox Compiles check out Overleaf documentation.

Enterprise

If you want help installing and maintaining Overleaf in your lab or workplace, Overleaf offers an officially supported version called Overleaf Server Pro.

Installation

Detailed installation instructions can be found in the Overleaf Toolkit. Configuration details and release history for the Extended Community Edition can be found on the Extended CE Wiki Page.

Overleaf Docker Image

This repo contains two dockerfiles, Dockerfile-base, which builds the sharelatex/sharelatex-base:ext-ce image, and Dockerfile which builds the sharelatex/sharelatex:ext-ce image.

The Base image generally contains the basic dependencies like wget, plus texlive. This is split out because it's a pretty heavy set of dependencies, and it's nice to not have to rebuild all of that every time.

The sharelatex/sharelatex image extends the base image and adds the actual Overleaf code and services.

Use make build-base and make build-community from server-ce/ to build these images.

The Phusion base-image (which is extended by the base image) provides a VM-like container in which to run the Overleaf services. Baseimage uses the runit service manager to manage services, and init scripts from the server-ce/runit folder are added.
