Describe the Feature you'd like

I was seeking for a way to conditionally include a variable in a VIEW. For example: 2 variables are defined: cmd and extra_args. I'd like to create a VIEW that expand to only cmd when extra_args is null: VIEW[{cmd}][text], otherwise the VIEW should expand to cmd -- extra_args: VIEW[{cmd} -- {extra_args}][text]. Note the -- is added in between.

I did not find a straightforward to do this. Please provide any hint if this is already supported.

If if condition can be supported, I think for loop over an array could be a thing too. This remind me of jinja2 template language, which I use regularly to handle complex templates.

Standard and math view fields use mathjs, which has ternary operators condition ? true : false. I won't add another language or extra language features to view fields, except possibly the Bases formula language, when it becomes available for plugins.

@mProjectsCode Thanks for the tips. Could you please give me an example, or probably include this in the doc? I tried several ways but couldn't make it to work. Thanks!

edit： I get tenary expression to work with [math], but couldn't append "--" on a string. It seems it's trying to convert "--" to a number.
