If you simply need the code, you can download an archive from the GitLab web interface. However, if there is a tiny chance that you might start developing, the recommended way is to clone the repository. See [[GitLab best practice#Roles]].

Every logged-in user can access the main repository, however only a small group of administrators has write access. To contribute, a user creates a '''fork''' (see [[Documentation#Creating_a_project_fork | here]]) from the repository. This is a repository copy in the Gitlab system where a single developer or a group of developers have full access.

A local copy of the repository is required on the working machine in order to work on the project. This copy is referred to be a '''clone''' (see [[Documentation#Making_local_working_copy | here]]).
 
=== Making local working copy ===
A project is utilized through a local working copy referred to be a ''clone''. The project can be cloned from either the main repository in the group space or the fork in the user space depending on the role.
 
In the examples replace ''user'' and ''wpn'' (e.g. wp7) appropriately.
 
'''Note''': the gitlab offers two modes for the link to be cloned, you can choose ''ssh'' (default setting) or ''https''. If you can not clone with the proposed default link, try option ''https://''.
 
==== From the main repository ====
The main repository is cloned like
    git clone https://gitlab.uib.no/pct/wpn.git
 
The upstream link can be changed later to any other repository like e.g. a development fork as follows (given the clone directory is the current working directory)
    git remote set-url origin https://user@gitlab.uib.no/user/wpn.git
 
The originally cloned remote repository will get the identifier ''origin'' in your local clone.
 
==== From development fork ====
Clone directly from your development fork
    git clone https://user@gitlab.uib.no/user/wpn.git
 
This will create a local directory ''wpn'', an optional argument after the link allows to change the directory name, e.g.
    git clone https://user@gitlab.uib.no/user/wpn.git mywork
 
==== Multiple upstream repositories ====
As a more advanced option, multiple remote repositories can be added to the clone. All remote repositories are referenced through their identifiers, e.g. ''origin'' pointing to the fork and  ''pctgroup'' pointing to main repository (chosen as an example).
    git remote add pctgroup https://gitlab.uib.no/pct/wpn.git
 
==== Check configured upstream repositories ====
The configured upstream repositories can be checked with
    git remote -v
This will display the identifier and link to the configured upstream repositories.
 
=== Pushing to development fork ===
Once you have added commits to e.g. the '''dev''' branch, those commits can be ''pushed'' upstream to the fork (if ''origin'' refers to the fork)
    git push origin dev
 
Or using the direct link
    git push https://user@gitlab.uib.no/user/wpn.git dev
 
=== Importing an external package ===
The project will use a couple of external packages which are hosted in a different master repository. Copies of such external packages can be added to the gitlab server under our project group to provide a consistent package.


Here is a proposed workflow for importing a package which is already hosted in git.
A local copy of the repository is required on the working machine in order to work on the project. This copy is referred to be a '''clone''', see [[GitLab Developer FAQ#How can I make a clone of a project in my fork]].
# Create new repository in the pCT group or ask for creation, lets call it ''newPackage''
# Fork the repository to your user space
# Clone the package you want to import
#:<pre> git clone <some_external_link> newPackage # we give it the new name</pre>
#:<pre> cd newPackage</pre>
# Redirect upstream URL to the fork in your gitlab user space
#:<pre> git remote set-url origin https://user@gitlab.uib.no/user/newPackage.git</pre>
# Now make a forced push (option ''-f'') to import the repository to your fork
#:<pre> git push -f origin</pre>
# Create merge request to branch ''import'' (if not existing, ''master'' or any other appropriate branch) by following the instructions [[Documentation#Pull/Merge request | Pull/Merge request]]

Software installation

Software repositories

We use the GitLab service hosted by IT of University of Bergen: https://git.app.uib.no/

Get access to the repositories - with UiB account

Open the UiB gitlab web interface.

Log in with your UiB account, then the administrators will give you access to the pCT group. Since authentication goes via Dataporten service, accounts from other Norwegian universities or institutions can be used in the same way.

Get access to the repositories - without UiB account

It is possible to use a github user account to login to the UiB GitLab, however such external users are not allowed to create forks in the GitLab domain. Since forks are mandatory for the development cycle, github logins can effectively only be used for read access. Again the repository administrators need to add you to the pCT group.

Guest accounts for external developers can be set up, get in contact with the group over the general channels

Further information on GitLab in general can by found on the following external webpages:


The specific instructions how to use the repositories within the pCT project are collected in the following pages:

GitLab Developer FAQ

Gitlab Master FAQ

Getting the code

If you simply need the code, you can download an archive from the GitLab web interface. However, if there is a tiny chance that you might start developing, the recommended way is to clone the repository. See GitLab best practice#Roles.

Development workflow

Every logged-in user can access the main repository, however only a small group of administrators has write access. To contribute, a user creates a fork from the repository. This is a repository copy in the GitLab system where a single developer or a group of developers have full access, see GitLab Developer FAQ#Working with forks.

A local copy of the repository is required on the working machine in order to work on the project. This copy is referred to be a clone, see GitLab Developer FAQ#How can I make a clone of a project in my fork.
