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
${c?b:f()}
is illegal becauseb:f()
is being parsed as a qualified function instead of part of a conditional expression. As usual, () can be used to make the precedence explicit, e.g${c?b:(f())}
.

QUESTION
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
...ANSWER
Answered 2021-Apr-07 at 12:15Move the Lexer rules for them to be prior to the Lexer rule for Identifier
.
If ANTLR has more than one Lexer rule that matches input of the same length it chooses the first rule in the grammar that matches.
For example “mod” is matched by Identifier
and MOD1
, but Identifier
is 1st, so it chooses Identifier
. Move the MOD1
rule to be before Identifier
and it’ll match MOD1
———-
BTW, unless you care about having different token values for “%” and “mod”, you can just define a single rule:

Answered 2021-Jan-27 at 19:55Looks like you are not dealing with the line return at the end of the line. Try:
NoiseMP3 = myfile[3].strip()
QUESTION
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?
...ANSWER
Answered 2021-Jan-28 at 05:35Since you do not use any of the columns of the CTE part other than EHRProgramWHID
, ProgramName
, ClientWHID
then there is no need to return them.
Without sample data I can't check this, but try:
QUESTION
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;

Answered 2021-Jan-18 at 12:56The idea is that x

are variables, e.g.,
