Octave Forge is a community project for collaborative development of GNU Octave extensions, called “Octave packages”. If you have a large package that you want to open up to collaborative development, or a couple of m-files that you want to contribute to an existing package, Octave Forge is the place to do it. Tiny helper functions (the equivalent of e.g., shell aliases) should go in the Tips and tricks page.
You can find the list of packages on the Octave Forge website. The recommended method for package installation is using your system package manager, see also the FAQ for the most common issues. The official Windows Installer bundles several packages so they don't have to be installed separately.
To install a package from the Octave Forge, at the Octave prompt type
pkg install -forge package_name. If your Octave version is below 3.4.0, you'll have to download the package file manually, and use
pkg install package_file_name.tar.gz.
Octave extensions are developed and released on SourceForge https://sourceforge.net/projects/octave/
- Writes individual function files (m-files, oct-files)
- Writes documentation, either for individual functions (function reference) or the package as a whole (package documentation / user manual)
- Writes tests, either for individual function files or the the package as a whole
- Writes demos for individual function files
- Contributes bug reports or feature requests, e. g., via the Octave bug tracker
- Contributes patches to fix errors, e. g., via the Octave patch tracker
- Maintains package content (m-files, C and fortran code, documentation, bundled libraries, other content) inside the source code repository, see . If the code is developed elsewhere, the repository must be pushed to Octave Forge at release time.
- Keeps the package in good shape, e. g., installability on many systems, up-to-date INDEX, DESCRIPTION, NEWS … files
- Manages package licensing
- Works towards a reasonable test suite for the package and ensures passing tests at release time
- Releases new versions of the package, see . It is recommended to use a Makefile at the top level of the repository to automate this task.
- Announces new package releases at both Octave mailing lists once they have been uploaded
- Answers bug reports and feature requests for the individual package. The maintainer has no obligation to provide a fix herself.
- Reviews patches for the individual package and decides whether they may be applied, e. g., coding style, help texts, tests, a new function matches the scope of the package
- Acts as a primary contact for downstream distributors
Forge release manager
- Answers the package release tickets (there is also an RSS feed).
- Reviews package release candidates (these are formal checks)
- The package lists at least one maintainer with valid contact information
- Up-to-date documentation
- Must install and work with the latest stable Octave release
- License compliance (must be released under a GPL compatible license)
- The corresponding source code revision must be tagged inside the Octave Forge repository and it must be possible to reproduce the content of the release tarball from this revision. Aforementioned Makefile can help with this task.
- Content has been signed by the package maintainer or matching hash values have been provided via the package release ticket
- All functions (except private ones) must be documented using Texinfo
- The package must have all the required files 
- If the package has a doc folder it should be written in Texinfo
- No Octave core functions should be shadowed
- No external dependencies should be directly included
- Uploads new releases
- Decides about entry of new packages to Octave Forge
- Categorizes the list of maintained and unmaintained packages
- Administrates the SourceForge project
- Manages the project
- Contributes new ideas to the project
- Makes strategic decisions
Suggested new features
- Install directory
- Install from URL / source code repository
- Build HTML / PDF docs
- Index, host documentation and archive releases of packages such as epstk which have been developed elsewhere (equivalent of CPAN). Feel free to expand on the definition of such a system on this page.
- Rapid code sharing of individual function files, see Agora.
