Failed to parse expression: "$((16#ffff))" decimal conversion

[fakuivan]

#!/usr/bin/env bash
function to_decimal () {
    echo "$(("$1"#"$2"))"
}
to_decimal 16 ff

The function to_decimal converts the number "$2" in base "$1" to decimal. The parser fails to recognize this instruction.

Thanks for reporting this issue. It seems to be a grammar issue.

I create an issue: tree-sitter/tree-sitter-bash#62

In my version of bash I actually get an error here:

"line 3: "16"#"ff": syntax error: operand expected (error token is ""16"#"ff"")"

$ bash --version

This seems to have been fixed in the newer version of the grammar
