Validating clipboard contents with contains command

I’m sure I’m missing something super simple here.

I’m trying to validate that the clipboard contents are correct user token. A correct token begins with "B$_".

This is what I’ve been attempting:


{if: contains(token, "B$_(.+)")}
{else}Oh no! It looks like the token is not copied to your clipboard properly.

Hi Peter,

The "contains()" function only works with plain text matches, it doesn't support regular expression syntax.

You want to use the "testregex()" function. Also you need to escape the "$" in the regex by putting a backslash before it as "$" has a special meaning in regular expressions, signifying the "end of the text".

Here's an example:


{if: testregex(token, "B\$_(.+)")}
{else}Oh no! It looks like the token isn't valid.

Aha! that works perfectly! Thanks Scott!

Heya Scott, I’ve been using this bit of code for a while and have run into a situation where I need to pass the resulting value on to use in other parts of the snippet. Is it possible to pass the result of this if statement into a urlload command?

Essentially filtering the contents of the clipboard to verify that it begins with B$_ and if not add it to the URL in the urlload.

Yes, that should be possible. Just include the {=token} in the URL you want to load.

Let me know if you run into any issues.

Aha, my apologies! I forgot I modified the example to consider if the clipboard contents contain B$_ or not and then add it if not. Currently this is what I have.

{if: testregex({clipboard}, "B$(.+)")}

Ideally if the token is copied without the B$_ I’d like to add it and insert that result into a urlload.

Sure, you should be able to do something like this:

{if: testregex({clipboard}, "B$(.+)")}
{token= "B$" & trim({clipboard})}{endif}
