Make a whole layer visible with SKILL

below is a simple skill function that scans all the Classes for a specific layer name & displays them:

procedure((view_layer \@optional (Layer ""))
let((Classes SubClasses layer)
foreach(Class ((axlGetParam "paramLayerGroup")->groupMembers)
foreach(SubClass ((axlGetParam sprintf(String "paramLayerGroup:%s/paramLayer" Class))->groupMembers)
when(equal(SubClass Layer)
axlVisibleLayer(strcat(Class "/" SubClass) t)
)
)
)
axlFlushDisplay()
(axlVisibleUpdate t)
)
)
axlCmdRegister( "view_layer" 'view_layer ?cmdType "general")

Hi,

Thanks for your quick answer but is it mandatory to have all these lines just to select the case "All" of the top line in color dialog because that's all I want.

Hello David,

I know it has been 2 years since you posted this code, but I just stumbled upon it, and while trying to make it work, I realized I had to change a line to have it display the layers.
As is, when I run the function (view_layer("INT2") for instance), it didn't displayed anything but returned t.

I change this line :
foreach(SubClass ((axlGetParam sprintf(String "paramLayerGroup:%s/paramLayer" Class))->groupMembers)

To this :
foreach(SubClass ((axlGetParam sprintf(String "paramLayerGroup:%s" Class))->groupMembers)
(I removed /paramLayer after %s)

And now it works. I am not exactly sure why 
If you still come around here, could you please tell me what is the meaning of this /paramLayer statement ? Do you know why it doesn't work for me ? Did SKILL changed since then ?

Anyway, thank you for this !
Best regards

That code was wrong, the paramLayer field should only be used to get the information for a specific subclass name, for example:

Skill > (etch_param = axlGetParam("paramLayerGroup:ETCH/paramLayer:TOP"))
param:00000090075950A0
Skill > etch_param->??
(objType "paramLayer" userDefined t thickness
"1.200000 mil" material "COPPER" type "CONDUCTOR"
number 0 drcPhotoType "positive" nextLayer
"GND" visible t parentName "ETCH"
name "TOP" isEtch t color
2 pattern 0
)

Thank you for the reply. That is what I thought after looking at the algroskill.pdf manual, but thought there might be something else I wasn't seeing about paramLayer.

To anyone who might be interested, I "updated" the procedure a bit, so that it toggle layers on/off. It also doesn't turn on the Boundary layer at all, because I only use it at some rare occasions, same could be done with via/route keepout and regions. if someone has a better idea to do this, don't hesitate to share ! At the moment the only issue I see is that if some of the subclasses are already turned on while the procedure is used, it will toggle them respective to their current state.

procedure(toggleLayer(\@optional (Layer ""))
let((Classes SubClasses layer)
foreach(Class (axlGetParam("paramLayerGroup")->groupMembers)
foreach(SubClass (axlGetParam(sprintf(String "paramLayerGroup:%s" Class))->groupMembers)
when(equal(SubClass Layer)
if(axlIsVisibleLayer(strcat(Class "/" SubClass))
then
axlVisibleLayer(strcat(Class "/" SubClass) nil)
else
axlVisibleLayer(strcat(Class "/" SubClass) t)
) ;if
) ;when
) ;foreach
axlVisibleLayer(strcat("BOUNDARY/" Layer) nil)
) ;foreach
axlFlushDisplay()
axlVisibleUpdate(t)
)) ;let,procedure
