What's the difference between [:something] & [something] & {something:something2} & {something} , etc.?

[fickle_123]

Is there a document link that explain when to use [:something] syntax like [:lastsale] , [:Value] , {Entity Name}, {Entity data:somevalue} , etc? and what really is the difference between them? are they variable? or entity? or entity’s attribute? or user’s input? and can we define our own variable?

I’ve also some case where no brackets are needed as well such as the “field name” parameter for “Update Entity Data” action.

thanks in advance

Excellent Question! I haven’t received a definitive answer to this question either, and it causes a lot of confusion. I will give it shot

Syntax breakdown for {braces}, [brackets], (brackets), :colons:, etc

{something} is a printer template tag. {something:something2} is a printer template tag, drilled-down to a more specific level. Printer Template tags can be read or referenced in many areas of SambaPOS, such as in Rules. For example, {TICKET TOTAL}, {ENTITY NAME:Customer}, or {ENTITY DATA:Customer:Address} can be read in Rules. {:something} is a reference to a value held in a Program Setting (variable) called something … you can create and modify your own variables using Action Update Prog…

Wow, That’s a very thorough explanation and really I appreciate it, QMcKay. It’ll certainly take a while for me to remember all that though:smile:

Thank you very much for that detailed explanation. We also have [=2+2] syntax for expressions. When listed seems really a lot
