PDM_IF bitwise-and comparsion

[Legacy User]

Hello team!

 

Referring to implementation guide I have found possibility to compare values by bitwise-and (PDM_IF &),

I have tried several times, but haven't found any working condition,

could anyone provide working example?

 

PS: I'm running sdm 12.7 CP2.

HTMPL:
<PDM_IF "2 & 0"><!-- return true -->
<PDM_IF 2 & 2><!-- return false -->

JS:
(2&0) // false;
(2&2) // true

I'll try to get to the VM to test a little later but please try:

 

<PDM_IF "2" & "0">

 

I seem to recall there is a more specific format required than what the Guide shows but I can't place it at the moment.

Thanks for reply!

I tried a lot of combinations, even "2 & 2" == "2", none of them are works... :C

It has been a very long time since I needed to do a bitwise comparison.  Is there a specific task you are trying to accomplish?

I have created new control, which is uses integer and can store multiple values, OOTB attribute like this is stored in USP_PREFERENCES and called web_preferences.

JS control already done and I'm planning to publish it as regular PDM_MACRO, but usablity question can ruin all my plans.

PDM_MACRO example (based on checkbox):

<PDM_MACRO name=dtlBitwiseAnd hdr="ENV: SolMan" attr="z_env" key="1" on="Yes" off="No">

<PDM_MACRO name=dtlBitwiseAnd hdr="ENV: SDM" attr="z_env" key="2" on="Yes" off="No">

<PDM_MACRO name=dtlBitwiseAnd hdr="ENV: Other" attr="z_env" key="4" on="Yes" off="No">

How it looks:

 

in my example z_env = 5.

Have you tried <PDM_IF "$args.z_env" == "5">

Hi CelsoA

Let's us know if you made it works as I think this can be useful for many

the question is still unresolved, I think that I tried all of combinations with "&" word, but didn't found correct syntax for PDM_IF bitwise-and comparsion

Hi  cdtj,

 

I believe that bit-wise comparisons in PDM_IFs are not well constructed. Why you don't use Javascript if? It should work as expected and you can use exactly the way you are wanting.

 

For example, instead of <PDM_IF 2 & 2></PDM_IF>, it would be: if (2 & 2) { }

Hi diogo.nobrega,

yeah, I'm using js, but my opinion is that:

- things described in Implementation Guide should work

- javascript code passes to customer pages instead of PDM tags that being cutted on page preprocessing.

Agree with you CDTJ when functionality is made available this must work as documented as we rely on it to develop our business process.

When you buy a car you expect the break pedal to work as expected and stop the car vs. any other behavior

You're right. I think that in this situation, this could be considered a bug, so you could open a case. Did you already do this?
