PyFVCOM

Due to a shift in policy, from 0900 GMT on Wednesday 14th July 2021, we will be disabling ssh access to the server for external users. External users who wish to continue to access code repositories on the server will need to switch to using https. This can be accomplished in the following way: 1) On the repo on gitlab, use the clone dialogue and select ‘Clone with HTTPS’ to get the address of the repo; 2) From within the checkout of your repo run: $ git remote set-url origin HTTPS_ADDRESS. Here, replace HTTPS_ADDRESS with the address you have just copied from GitLab. Pulls and pushes will now require you to enter a username and password rather than using a ssh key. If you would prefer not to enter a password each time, you might consider caching your login credentials.

Conda builds

With a few tweaks, it should now be possible to build and install PyFVCOM using conda, which provides greater flexibility with respect to the handling of dependencies (e.g. basemap).

To do this, install miniconda3 in a location of your choosing. Then, activate conda; add the conda-forge channel; and install conda-build and conda-verify, which we will use to install PyFVCOM. For example:

$ source /opt/miniconda/miniconda3/bin/activate
$ conda config --append channels conda-forge
$ conda install conda-build conda-verify

The above code will install miniconda3 into the directory /opt/miniconda, once the appropriate write permissions have been set (the default is to install miniconda3 into your home directory, which is, of course, also fine).

With miniconda3 installed and configured, create a new environment in which to install PyFVCOM using the following commands:

$ conda create -n pyfvcom
$ conda activate pyfvcom

Next, clone PyFVCOM using git. The code below assumes that you have configured ssh access to GitLab:

$ mkdir -p $HOME/code/git/fvcom && cd $HOME/code/git/fvcom
$ git clone git@gitlab.ecosystem-modelling.pml.ac.uk/fvcom/pyfvcom.git
$ cd pyfvcom
$ git checkout dev

Next, open up setup.cfg and comment out user in the install section - this will prevent conda from trying to install PyFVCOM is your user space rather than the new conda environment you have created.

Finally, build and install PyFVCOM using conda:

$ conda build .
$ conda install -c local PyFVCOM

This is a local build. However, it is now a fairly simple procedure to submit the package to anaconda, which would make it possible to install PyFVCOM in one command. Is this desirable?
