GSI extension for pjlsa
This pjlsa extension provides access to the GSI control systems.
The Python module pjlsa (developed by CERN) provides access to the LSA API.
See also the GSI-hosted pjlsa version for further information on pjlsa.
Use
A simple example is provided in example.py. It prints all available patterns:
import pjlsa_gsi
with pjlsa_gsi.LSAClientGSI(server='gsi-int').java_api():
from cern.lsa.client import ServiceLocator, ContextService
contextService = ServiceLocator.getService(ContextService)
patterns = contextService.findPatterns()
for pattern in patterns:
print (pattern)
Running this script within ASL, the accelerator services cluster, would give a typical output:
BUILD SUCCESSFUL in 1s
1 actionable task: 1 executed
[... INFO and DEBUG messages from LSA running on GSI integration server]

You can either directly pip-install from git
$ python -m pip install 'pjlsa_gsi @ https://git.gsi.de/scripting-tools/pjlsa_gsi/'or first clone this repository explicitly and then directly pip-install from there,
$ git clone https://git.gsi.de/scripting-tools/pjlsa_gsi.git
$ cd pjlsa_gsi
$ pip install .Note that this package will install cmmn-build-manager and pjlsa from the GSI internal gitlab. You may be asked to provide your GSI weblogin credentials for git to log in.
Note also that, upon your first call of the GSI LSA client, a couple of minutes may be spent on downloading the jars via gradle from the servers.
