Dollar sign is not printed in text block

At a glance

The post is about a user experiencing an issue where the dollar sign is not being displayed when using the syntax ${{variable_name}}. Community members suggest that this seems to be a bug, and provide several workarounds:

1. Adding a space between the $ and the variable, but this results in the space being printed as well.

2. Using a variable for the dollar sign and another variable for the value, then combining them as {{dollar}}{{value}}.

3. Modifying the regular expression used to parse the variables, as it seems to be the cause of the issue.

There is no explicitly marked answer, but the community members provide helpful suggestions and discuss potential solutions to the problem.

Why aren't the dollar signs being displayed in the text block when I use the following ${{variable_name}}?

seems like a bug

try putting a space between $ and variable

nnefer_l

I tried that and the space is printed like $ 9.99

one workaround would be to use $ itself inside a variable. In that case, you could have both variables side by side without any space in between. that'd resolve this

Thanks for your suggestion.

It's seems like that would fix the empty space issue and creates another problem...

If I save a variable as

Plain Text

$9.99

rather than

Plain Text

9.99

, I won't be able to do math operations on it.

no i mean to say take a variable dollar = $ and another variable value = 9.99.
and then merge both like {{dollar}}{{value}}

aahsmha

this way it's working

nnefer_l

Oh, I see what you mean now! Nice workaround 👌🏻

@Baptiste

Plain Text

// {{variable}} and ${{{variable}}}
const variableRegex = /\{\{([^{}]+)\}\}|(\$)\{\{([^{}]+)\}\}/g;

this regex seems to be causing the issue. it considers ${{var}} instead of {{var}} . What do you think would be the appropriate fix for this?
I think if we change the regex itself for getVariablesToParseInfoInText function, that way it'll be solved.
