The text/template package now correctly reports errors when a
|
||||
parenthesized argument is used as a function.
|
||||
This most commonly shows up in erroneous cases like
|
||||
<code>{{if (eq .F "a") or (eq .F "b")}}</code>.
|
||||
This should be written as <code>{{if or (eq .F "a") (eq .F "b")}}</code>.
|
||||
<code>{{"{{"}}if (eq .F "a") or (eq .F "b"){{"}}"}}</code>.
|
||||
This should be written as <code>{{"{{"}}if or (eq .F "a") (eq .F "b"){{"}}"}}</code>.
|
||||
The erroneous case never worked as expected, and will now be
|
||||
reported with an error <code>can't give argument to non-function</code>.
