OMERO.web

Introduction

OMERO.web provides a web based client and plugin infrastructure.

Dependencies

Direct dependencies of OMERO.web are:

Installation

We recommend installing omero-web in a Python virtual environment. Here we show the install using Conda. For more details and other options, please see OMERO.py.

conda create -n myenv -c conda-forge python=3.8 zeroc-ice omero-py
conda activate myenv
pip install omero-web

Setting of the environment variable OMERODIR is required. $OMERODIR/var/log/ directory will contain log files. $OMERODIR/etc/grid/config.xml is used to store config:

export OMERODIR=$(pwd)

Usage

For running omero-web in production with nginx, see See: OMERO.web install documentation. To run in development mode, see below.

Contributing

See: OMERO documentation

Developer installation

For a development installation we recommend creating a virtual environment as described above. Then install OMERO.web into your virtual environment as an editable package, so that any edits to source files will be reflected in your installation.

git clone https://github.com/ome/omero-web
cd omero-web
pip install -e .

Note some omero-web tests may not run when this module and/or omero-py are installed in editable mode.

Configuration for developer usage:

omero config set omero.web.debug True
omero config set omero.web.application_server development

# If you want to connect to OMERO.server other than 'localhost'
omero config append omero.web.server_list '["demo.openmicroscopy.org", 4064, "demo"]'

Then run omero-web in the foreground with:

omero web start
...
Starting development server at http://127.0.0.1:4080/

Or, run Django directly:

cd omero-web
python omeroweb/manage.py runserver 4080
...
Starting development server at http://127.0.0.1:4080/

Upgrading

Plugin developers should review the Upgrading document highlighting steps that may need to be taken when upgrading OMERO.web to ensure plugins or other customizations continue to function as expected.

Running tests

Unit tests are located under the test directory and can be run with pytest.

Integration tests

Integration tests are stored in the main repository (ome/openmicroscopy) and depend on the OMERO integration testing framework. Reading about Running and writing tests in the OMERO documentation is essential.

Release process

This repository uses bump2version to manage version numbers. To tag a release run:

$ bumpversion release

This will remove the .dev0 suffix from the current version, commit, and tag the release.

To switch back to a development version run:

$ bumpversion --no-tag patch

NB: this assumes next release will be a patch (see below). To complete the release, push the master branch and the release tag to origin:

$ git push origin master v5.8.0

If any PRs are merged that would require the next release to be a major or minor version (see semver.org) then that PR can include a version bump created via:

$ bumpversion --no-tag minor|major

If this hasn't been performed prior to release and you wish to specify the next version number directly when creating the release, this can be achieved with:

$ bumpversion --new-version 5.9.0 release

omero-web-docker

Following omero-web release, need to update and release omero-web-docker.
