Is there a way to use variables in Less for the ~ operator, like ~"calc(100% - @spacing)";
CssLessCss CalcCss Problem Overview
Is there a way to use variables in less ~
operator, like
~"calc(70% - @spacing)";
When I have tried it it only works with static values like
~"calc(70% - 10px)";
Can I get the string to be evaluated prior to beeing set as a property.

To disable the calculation which LESS does automatically when discovering a -
between two numeric values but still being able to use variables, you can write one of the following:
-
Only escape the operator that triggers the calculation and use the variable like you normally do
@padding: 20px; body { padding: calc(100% ~"-" @padding); }
-
Escape the whole expression and interpolate the variable with the
@{padding}
notation@padding: 20px; body { padding: ~"calc(100% - @{padding})"; }
I prefer the second version, since it resembles javascript's template literals and looks a bit cleaner, but either way works just fine.
Both solutions disable the automatic Less calculation and compile to the correct result:
body {
padding: calc(100% - 20px);
}
