Create a Python extension

Pierre_20718

Hi,

I'm trying to create a Python extension for Hyperview (2024), with a button in the ribbon for an existing script.

I got this error:

Traceback (most recent call last):
File "S:/GitLab-Runner/builds/TqqBBs8CP/0/altairengineering/modvis/common/common/framework/win64/hwx/bin/win64/hwsigslot.py", line 1620, in _Emit

File "<string>", line 1
rescale(<generator object execcallback.<locals>.<genexpr> at 0x000001EE3EC14740>)
^
SyntaxError: invalid syntax

And my source files are :

extension.xml :

<section name="Extension">
	<! … some stuff with name, version, etc. —>
	<entry name="tclscript"			value="global-init.tcl" />
	<entry name="script"			value="global-init.py" />
	<section name="profile" value="HyperView">
		<entry name="ribbonxml" value="hv/hv-ribbon.xml" />
		<entry name="script" value="hv/hv-init.py" />
	</section>
</section>

Global-init.py and global-init.tcl are pretty empty (I start with a first button before to do more) :

import hw

from hw import hv

package require postquery

namespace eval ::MyExtension {

global env

variable workDir [file normalize [[::hwp::GetSession] GetSystemVariable CURRENTWORKINGDIR]]

}

hv/hv-ribbon.xml

<root>

	<actionlist>

		<action

			tag="Ext_Ribbon_HV_Action_rescale"

			text="Rescale legend"

			tooltip="Rescale the legend with an exponential scale"

			image="scale.png"

			command="py: rescale"

		/>
	</actionlist>
	
	<page tag="Ext_Ribbon_HV_Ribbon_testone" text="TEST ONE">
		<group tag="Ext_Ribbon_HV_Ribbon_testonegroupone" text="GROUP ONE">
			<action actiontag="Ext_Ribbon_HV_Action_rescale"/>
		</group>
	</page>
</root>

hv/hv-init.py :

import sys

import hw

from hw import hv



def rescale(*a, **kwargs):


    print("hello world!")

    #return _rescale()  # not working, so I try to only run a print…

    return 0

What's wrong ?

Thanks,

Pierre

Hello @Pierre_20718 ,

The function rescale must belong to a module, and then () must be added to the end as a function call. The path to the modeul "themodulename" must be added to sys.path

command="py: rescale"

command="py: themodulename.rescale()"

Best Regards,

Michael
