Michael Osipov updated VELOCITY-960:
------------------------------------
Description:
Regarding the use of hypens on identifiers, the documentation doesn't look
consistent. Which one is recommended?
[Here|https://velocity.apache.org/engine/2.3/configuration.html] states the
following:
*{{parser.allow_hyphen_in_identifiers = false}}*
{quote}This is a backward compatibility option, false by default, which allows
the '{*}{{-}}{*}' character inside variable identifiers (available since 2.1).
If enabled, be warned that you will have to surround the mathematical minus
sign with spaces for it to be correctly interpreted.
{quote}
But [here|https://velocity.apache.org/engine/2.3/vtl-reference.html], the
configuration is different:
{quote}{{If the *parser.allows.dash.identifiers*}} configuration value is set
to true, then the *-* dash is also allowed in identifiers (and must be
surrounded by spaces to be interpreted as an arithmetic minus operator).}}
{quote}
