param: manage Libervia parameters¶
param commands allows to retrieve or set parameters as well as to export/import them
to a XML file.
Parameters are retrieve using a category and a name, they are both case sensitive.
category is the name of the tabs that you see when you set parameters in a frontend
like Cagou or Libervia.
Note
You need to have your session started to retrieve of modify parameters. If you can’t
or are not willing to connect for any reason (e.g. no internet connection), you can
use the --start-session option to start the profile session without connecting it
to the XMPP server.
get¶
Retrieve list of categories, parameters or a specific parameter value:
without argument, you’ll get the list of categories
with only a category specified, you’ll get a list of parameters and their values
with a category and a name, you’ll get the value or requested attribute of the specified parameters
By default you’ll get the value of the parameters, but you can request an other attribute
(for instance its type or constraint) using the -a ATTRIBUTE, --attribute
ATTRIBUTE argument.
You can set a security limit to retrieve only parameters allowed with this limit.
Security limit is an integer used in some frontends (like Libervia), to restrict
parameters modifiable by non privileged users. You can set it using --security-limit
SECURITY_LIMIT, by default it is disabled (i.e. all parameters are returned).
examples¶
Get list of categories:
$ li param get
Get list of parameters in General category:
$ li param get General
Get JID set for default profile. It is set in Connection category, with the parameters
named JabberID (be careful with the case):
$ li param get Connection JabberID
Get the type of the check_certificate parameters in Connection category:
$ li param get Connection check_certificate -a type
Get the constraint of the Priority parameters in Connection category:
$ li param get Connection Priority -a constraint
set¶
As expected, this command set a Libervia parameter. The category, name and value
are needed as positional arguments.
--security-limit SECURITY_LIMIT can be used if you want an update to be rejected if
the parameter is not modifiable with this limit. This can be useful if you use li from
an external tool and you want to limit damage risks, or for testing purpose.
examples¶
Use Markdown syntax for composition (e.g. for editing blog posts):
$ li param set Composition Syntax markdown
Try to change jid of the profile with a low security limit, this command should fail:
$ li param set --security-limit 0 Connection JabberID some_random_jid@example.org
save¶
Save the parameters structure to an external files. The parameters are saved as XML. The only expected argument is the path to the destination file.
Note
it’s the parameters structure and not the parameters values which are saved. This is low level method and most end users won’t probably need it
example¶
Save parameters structure to ~/parameters.xml:
$ li param save ~/parameters.xml
load¶
Load and merge the parameters structure from external XML files. The only expected argument is the path to the source file.
Note
it’s the parameters structure and not the parameters values which is loaded and merged. This is low level method and most end users won’t probably need it
example¶
Load and merge parameters structure from ~/parameters.xml:
$ li param load ~/parameters.xml
