The code is not a monolithic piece of software but a collection of independent packages that may be installed independently. The Installer script has been designed for the purpose.
Tips for developers¶
How to use git¶
The repository of bigdft-suite is in gitlab. For each developer, it is safe to clone its own repository.
Each developer has its own devel branch which has to be a copy of the bigdft-suite branch (called main).
Only the command
git pull main devel will be used to update your devel branch.
It is highly recommended not to develop in your devel branch!
For each set of modifications, start a new branch with
git checkout -B newbranch from the devel one.
Then you do your modifications, commits and so on.
Before the merge request, you have to update your newbranch branch from the devel branch
(which will be updated from the main one) with
git rebase devel and solve the conflicts if necessary.
Then go to gitlab and do a merge-request. Finally do not change your newbranch branch because the merge request will be
affected. In function of the remarks of the reviewer, you change you newbranch branch, do a
git pull origin newbranch to propagate the commits.
Choose the correct package in which to insert the developments¶
The first question to ask yourself is the generality of the
functionality you are going to implement.
The spirit is to work at the lowest possible level for a given task.
The idea is to make available the functionality also to other potential
users of the
This will also help in a better structure of the API of each package.
For instance, suppose you would like to implement a continuum solvent
cavity determination for a particular DFT run of a molecular system.
The correct level of development in this case would be the
package, as this is presently dealing with continuum solvents and cavities.
For a general overview one might say that:
futiledeals with low-level functionalities like
stdlib(but for FORTRAN). New MPI wrappers, strategies for memory copy and allocations should be implemented there.
at_lablibrary (will) deal with all the operations which are associated to position
Read the coding rules¶
For some inspiration on coding style and strategies, please read:
Create a test for the functionality¶
Each of the packages has its own continuous integration procedure, refer to it for a suitable implementation.
psolver: F_REGTEST_INSTRUCTION (to be documented)
Build and improve the BigDFT-suite’s documentation¶
From version 1.8.3, sphinx is used to build the documentation.
requirements.txt gives the list of python packages used to build the documentation.
which can be installed with
pip install -r requirements.txt
Then, perform in the source directory
The full documentation can be installed in website.
Document the API of the high-level routines¶
