I'm not sure where the inconsistency is? Can you elaborate?<br>
<br>
You can get the inputs from the tosca.inputs attribute without
passing any input parameters:<br>
<br>
tosca = ToscaTemplate(sys.argv[1])<br>
<br>
print([input.name for input in tosca.inputs])<br>
<br>
['cpus', 'db_name', 'db_user', 'db_pwd', 'db_root_pwd', 'db_port']<br>
<br>

<div>That approach seems fair enough, but inconsistent with how
other things are represented as functions. How am I meant to
know what the inputs to the CSAR are before the CSAR is
parsed?</div>

<br>
tosca-parser expects that the input values will be defined
already and passed to the ToscaTemplate object in the
parsed_params argument.<br>
<br>
If you change:<br>
<br>
tosca = ToscaTemplate(sys.argv[1])<br>
<br>
to:<br>
<br>
tosca = ToscaTemplate(sys.argv[1], parsed_params={'cpus':
4})<br>
<br>
the output becomes:<br>
<br>
Processing node template server<br>
disk_size: 10 GB<br>
num_cpus: 4<br>
mem_size: 4096 MB<br>
architecture: x86_64<br>
type: Linux<br>
distribution: Fedora<br>
version: 18.0<br>
min_instances: 1<br>
max_instances: 1<br>
secure: True<br>
<br>
<br>
Hope this helps.<br>

<div>I'm trying to use tosca-parser to parse CSAR
files. Its working quite well, until I hit a wall
with capabilities today. Specifically I am testing
with the single instance wordpress example CSAR,
which uses a get_input for the num_cpus argument
for host capabilities for the server.</div>
<div><br>
Based on how properties work, I would expect to
get a function back for anything which requires
referencing another value, but in the case of
capabilities I either get the hardcoded value
(strings, ints etc), or a None for values which
would be functions if we were talking about
prototypes.</div>
<div><br>
</div>
<div>Here's a snippet of example code:</div>
<div><br>
</div>
<div>
<div>#!/usr/bin/python</div>
<div><br>
</div>
<div>import sys</div>
<div><br>
</div>
<div>from jinja2 import Template</div>
<div>import toscaparser.functions</div>
<div>from toscaparser.tosca_template import
ToscaTemplate</div>
<div><br>
</div>
<div>tosca = ToscaTemplate(sys.argv[1])</div>
<div><br>
</div>
<div>for nodetemplate in tosca.nodetemplates:</div>
<div> print</div>
<div> print('Processing node template %s'% <a
href="http://nodetemplate.name"
target="_blank" moz-do-not-send="true">nodetemplate.name</a>)</div>
<div><br>
</div>
<div> capabilities =
nodetemplate.get_capabilities_objects()</div>
<div> for cap in capabilities:</div>
<div> propobjs =
cap.get_properties_objects()</div>
<div> if not propobjs:</div>
<div> continue</div>
<div><br>
</div>
<div> for po in propobjs:</div>
<div> print(' %s: %s' %(<a
href="http://po.name" target="_blank"
moz-do-not-send="true">po.name</a>, po.value))</div>
</div>
<div><br>
</div>
<div>Which returns this:</div>
<div><br>
</div>
<div>
<div>$ python _capabilities.py csar_wordpress.zip </div>
<div>No handlers could be found for logger
"tosca.model"</div>
<div><br>

<div> version: 18.0</div>
<div> type: Linux</div>
<div> architecture: x86_64</div>
</div>
<div><br>
</div>
<div>I would expect num_cpus for the "server"
node_template to be a GetInput() function based on
its definition in the CSAR, but instead I get
None.</div>
<div><br>
</div>
<div>Is there an example somewhere of how to
correctly access functions for capabilities?</div>
<div><br>
</div>
<div>Thanks,</div>
