High-level interfaces to the qalx API

pyqalx

Interfaces to qalx. For more details, see project documentation,.

development status

pyqalx is currently under active development. It is pre-version 1.0 beta software and so each minor version can introduce breaking changes.

qalx (an abbreviation of “queued calculations” and pronounced “kal-x”) is a flexible data management platform for engineering projects. Users store data and files in qalx and it provides tools for passing that data between various systems for processing.

There will eventually be four ways to interact with the platform:

• A Python interface (pyqalx)

• REST API (api.qalx.io)

• Web console (qalx.io) - coming soon

• A command line interface (qalx-cli) - coming soon

Most users are expected to use the web console and either the python or command line interfaces. The REST API is intended to be used if you prefer to access the platform with a language other than Python or want to create a custom interface.

Installing

qalx is written in Python and can be installed via the Python Package Index (PyPi) with:

pip install pyqalx

If installation has completed properly you should be able to import pyqalx in a python console:

>>> import pyqalx

Warning

pyqalx requires Python versions above 3.6.

Configuration and Authentication

Everything you do with qalx requires you to be authenticated. That is, the platform requires you to identify yourself and will record all your actions as being performed by you.

The way that qalx knows who you are is by reading a TOKEN which must be sent with every request.

Warning

During this beta phase, you have to request a TOKEN by registering your interest at qalx.io

The easiest way to make sure that your token is sent with every request is to make sure you have a valid .qalx file saved in your HOME directory.

where is HOME?

The HOME directory can usually be found by putting %USERPROFILE% in the address bar in Windows Explorer or it is simply ~ on unix systems.

qalx CLI configure

You can either add the TOKEN manually to the config file or you can use the qalx cli to do this for you automatically

$ qalx configure

The above command will ask you all the necessary questions to create your user and bot config files.

You can also create other profiles using the qalx configure command. You can even create profiles just for bots or just for users - or provide extra arguments to write to the config

# Will write a user profile called `dev` to the config file,
# will also write a `default` bot config profile
$ qalx --user-profile dev configure

# Will write a bot profile called `dev` to the config file,
# will also write a `default` user config profile
$ qalx --bot-profile dev configure

# Will not write the bot profile
$ qalx configure --no-bot

# Will not write the user profile
$ qalx configure --no-user

# Will write a default user and bot profile and will also write two
# extra keys to each config - `CUSTOMKEY=customvalue`
# and `CUSTOMKEY2=customvalue2`
$ qalx configure customkey=customvalue customkey2=customvalue2

Manual configuration

If you don’t want to use the qalx cli to configure your profile (or if you want to make changes to it in the future) then you can configure the profile yourself by adding the TOKEN to your config file under the default profile.

[default]
TOKEN = 632gd7yb9squd0q8sdhq0s8diqsd0nqsdq9sdj

Any other configuration settings can be stored in the same file see configuration for more information.
