Concatenation with backtick (escape) strings

[gary-menzel]

I have a situation where fields in a record are indexed but also contain spaces. For example first field 1, first field 2, first field 3, etc. And I need to iterate over those and create the field name dynamically. I can use $lookup but it would be nice if I could use the backtick approach but still either be able to concatenate the index of a map or if backticks supported interpolation in some way.

I've looked though both the OPEN and CLOSED issues and while I have seen some others asking about interpolation with backticks, I thought this was a very specific use case to add weight to a solution.

I can continue to use $lookup but it would be nice to have a simpler way to generate references with spaces and other variable data.

Using this as a starting point, If I understand you right, instead of:

$.Account.`Account Name`

you want to be able to do something like:

$.Account.`Account $prop`

The backticks are similar to the single tick in bash; all characters inside are treated as literal. So it's not likely to support anything like interpolation. Using $lookup is the way to go. I could envision some way to force a string back to a pathing operand, something like:

$.Account.$symbol("Account " & $prop)

But I am not a project owner or maintainer, so that's just my two cents.
