The standard way to access your suites is to use sync_local() , i.e.
| Code Block |
|---|
| language | py |
|---|
| title | synsync_local |
|---|
|
import ecflow
ci = ecflow.Client("my_host",3141) # replace the host and port with your own.
ci.sync_local() # download all the suites on the server
print (ci.get_defs()) |
The code above will suffice for the vast majority of cases. However if you have several suites, and are only interested in a subset, then the method above is not the most optimal. This method will be lot quicker.
| Code Block |

| language | py |

| title | ch_register |

|
import ecflow
ci = ecflow.Client("my_host",3141) # replace the host and port with your own.
suites_of_interest = [ 's1', 's2' ] # These are the *only* suites that I anam interested in
ci.ch_register(False,suites_of_interest) # register interest in the suites
ci._sync_local() # sync_local() will now ONLY return the suites s1,s2
print (ci.get_defs())
ci.ch_drop() # remember to remove our registration, otherwise it stays in the server |
