Spring expression: please provide additional convenience operators for comparisons [SPR-5518]

[spring-projects-issues]

Oliver Becker opened SPR-5518 and commented

The SPEL grammar requires <, >, <=, >=, etc for comparisons. Since these operators must be escaped as entity references when used within XML, it would be good to have the following extra operator notations for convenience:
lt for <
gt for >
le for <=
ge for >=

as well as
eq for ==
ne for !=

Also the following would be good:

div for /
mod for %
not for !

empty for [not sure if there is an antlr type for this one]

Support committed for these textual alternative representation for operators:

lt for <
gt for >
le for <=
ge for >=
eq for ==
ne for !=
div for /
mod for %
not for !

they are also case insensitive.

I don't know what you want for 'empty' - if you give me an example then I'll see what I can do.

I have yet to do the required doc updates for this.

Doc updates are complete for the textual equivalents for each operator. No feedback received on 'empty' so haven't done anything about that.
