## Introduction
The nomad infrastructure consists of a series of nomad and 3rd party services:
- nomad worker (python): task worker that will do the processing
- nomad api (python): the nomad REST API
- nomad app (python): the nomad app and it's REST APIs
- nomad gui: a small server serving the web-based react gui
- proxy: an nginx server that reverse proxyies all services under one port
- elastic search: nomad's search and analytics engine

### C libs
Even though the NOMAD infrastructure is written in python, there is a C library
required by one of our pyhton dependencies.
#### libmagic
Libmagic allows to determine the MIME type of files. It should be installed on most
unix/linux systems. It can be installed on MacOS with homebrew:
brew install libmagic
### Virtual environment
#### pyenv
The nomad code currently targets python 3.6. If you host machine has 3.7 or later installed,
you can use [pyenv]( to use python 3.6 in parallel.
While in principle everything should be compatable with 3.7 and later there have been
issues with some dependencies and requirements not being compatible with 3.7
To use 3.7 there is a slight issue about the `enum34` which fails the compilation of the
`mdtraj` and `mdanalysis` packages. A possible work arround is to uninstall and tham re-install
`enum34` once the other packages are installed.
#### virtualenv
We strongly recommend to use *virtualenv* to create a virtual environment. It will allow you
to keep nomad and its dependencies separate from your system's python installation.
Make sure to base the virtual environment on Python 3.

#### Conda
If you are a conda user, there is an equivalent, but you have to install pip and the
right python version while creating the environment.
conda create --name nomad_env pip python=3.6
conda activate nomad_env
To install libmagick for conda, you can use (other channels might also work):
conda -c conda-forge install --name nomad_env libmagic

the steps and run them manually, read on:

### Install NOMAD-coe dependencies.
Nomad is based on python modules from the NOMAD-coe project.
This includes parsers, normalizers, python-common and the meta-info.
Those dependencies are managed and configured via python in
`nomad/`. This gives us more flexibility in interacting with
different parser, normalizer versions from within the running nomad infrastructure.
This includes parsers, python-common and the meta-info. These modules are maintained as
their own GITLab/git repositories. To clone and initialize them run:
To run the dependencies script and install all dependencies into your environment:
git submodules update --init
This will checkout the proper version of the respective NOMAD-coe modules, install
further requirements, and install the modules themselves. The `-e` option will install
the NOMAD-coe dependencies with symbolic links allowing you to change the downloaded
dependency code without having to reinstall after.
All requirements for these submodules need to be installed and they need to be installed
themselves as python modules. Run the `` script that will install
everything into your virtual environment:
./ -e

### Configure the containers
The *docker-compose* takes some configuration from the environment. Environment
variables are set in `.env`, which is a link to either `.env_local` (intended to run
nomad for development on a local computer) and `.env_processing` (indented to run
nomad on nomad in *'production'*, currently on the enc pre-processing machine).
You can configure host ports, volume locations for host bindings, and these sort of things.
## Accessing 3'rd party services
Usually these services only used by the nomad containers, but sometimes you also
need to check something or do some manual steps.
The file `ops/docker-compose/nomad/.env` contains variables that control the ports
used to bind internal docker ports to your host machine. These are the ports you
have to use to connect to the respective services.
The *docker-compose* can be overriden with additional seetings. See documentation section on
operating NOMAD for more details. The override `docker-compose.override.yml` will
expose all database ports to the hostmachine and should be used in development. To use
it run docker-compose with `-f docker-compose.yml -f docker-compose.override.yml`.

You can run the worker, app, and gui as part of the docker infrastructure, like
seen above. But, of course there are always reasons to run them manually during
development, like running them in a debugger, profiler, etc.

nomad run worker
nomad admin run worker
To run it manually with celery, do (from the root)
To run it directly with celery, do (from the root)
celery -A nomad.processing worker -l info
You can use different debug level (e.g. switch `info` to `debug`)
Use watchdog during development to reload the worker on code changes.
Watchdog is part of the requirements-dev.txt. For MacOS (there is currently a bug in watchdog)
uninstall and install this [fixed]( version
Run the app via docker, or (from the root):
pip uninstall watchdog

Now use this to auto relead worker:
You can also run worker and app together:

### Run the api

Or manually:

### Run the gui
### GUI
When you run the gui on its own (e.g. with react dev server below), you have to have
the API running manually also. This *inside docker* API is configured for ngingx paths
and proxies, which are run by the gui container. But you can run the *production* gui

## Setup your (I)DE
The documentation section on development guidelines details how the code is organized,
tested, formatted, and documented. To help you meet these guidelines, we recomment to
use a proper IDE for development and ditch any VIM/Emacs (mal-)practices.
