In the specification for the Jakarta Expression Language there is the following condition:

Qualified functions with a namespace prefix have precedence over the operators. Thus the expression ${c?b:f()} is illegal because b:f() is being parsed as a qualified function instead of part of a conditional expression. As usual, () can be used to make the precedence explicit, e.g ${c?b:(f())}.

I'm trying to parse expressions from the Jakarta Expression Language. In summary, it is a simplified Java expressions, with addition of a few things:

• Support for creating maps like: {"foo": "bar"}
• Support for creating lists and sets like: [1,2,3,4] {1,2,3,4}
• Use some identifiers instead of symbols, like: foo gt bar (foo > bar), foo mod bar(foo % bar), and so on.

I'm struggling in the last bit, where it always understands the "mod", "gt", "ge" as identifiers instead of using the expression that has the "%", ">", ">=".

I'm new to ANTLR. My grammar is based on the Java grammar in the https://github.com/antlr/grammars-v4/tree/master/java/java and the JavaCC provided by: https://jakarta.ee/specifications/expression-language/4.0/jakarta-expression-language-spec-4.0.html#collected-syntax

I have the following code, which calculates # of unique Clients [ClientWHID] and # of days for these clients when they were homeless, 12 months after entering specific hospital(s) ([Program]), plz see below.

I am wondering, if there is more elegant way to write this code? For example, to replace my sub select in parentheses cte with CASE statement? Or is it not possible in this situation?

Python newbie here.

I have a library function that is expecting a formula object; solver.Add(x + y < 5)

However my formula is dynamic and being provided from another system as a string "x + y < 5"

The library function doesn't not accept a string, my question is there a way to create a function that can evaluate my string and return the formula as an object? eg solver.Add(evaluateFormula("x + y < 5")) or solver.Add(evaluateFormula("x + y") < 5)

Using the built in eval() does not work for this type of formula since that tries to execute the formula which is not what I want to do.

Here's some full sample code;

I'm using Pandas for some data cleanup, and I have a very long regex which I would like to split into multiple lines. The following works fine in Pandas because it is all on one line:

I have written a parser using megaparsec for a very simple language consisting of integer literals and two unary operators "a" and "b":
