amount multipliers based on the value of a tag

[mail....@gmail.com]

Hi, 

Can an "amount multiplier" in an "automated transaction" be based on the value of a tag?

Something like: 

= /My:Bank:?/ & %/SHARED/

    (Me->Roommate)            to_val(tag("SHARED"))

Basically, I want to achieve parameterized sharing between e.g., me and a roommate.

Thanks,

Dimitar

Sounds like an interesting idea. You'd have to use this:

(Me->Roommate) (to_val(tag("SHARED")))

Not sure if it works, though!

It appears to work (it helps me to considerably simplify my design). I used

(Me->Roommate) (to_amount(tag("SHARED")))

The documentation of `to_amount` says "For internal use only". Is there
a more appropriate function that I can use? And one more thing: it would
be nice to be able to specify fractional amounts, e.g., "SHARED: 1/3"
instead of "SHARED: .0333333" (but `to_amount` doesn't seem to support
this). Any ideas?

Thanks,

Use:
; SHARED:: (1/3)

as in:

2020-06-24 * Test
; SHARED:: (1/3)
Assets:My:Bank:Foo 30.00
Assets:Test

Indeed, the documentation explains it well (I must have missed it) -
thanks.

It appears that, in this case, the braces are optional and one can
use ; SHARED:: 1/3. Furthermore, if one uses the SHARED:: construct,
`to_amount` in no longer necessary.

This is correct. `::` interprets the metadata value as an amount, whereas `:`
takes it as a plain string.
