Summary: [grammar] template declaration/instance must take one
or more arguments?
Product: D
Version: D2
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: websites
AssignedTo: nobody puremagic.com
ReportedBy: k.hara.pg gmail.com
I found a funny grammar bug.
In current, nonterminal TemplateDeclaration symbol is defined as follows.
http://dlang.org/template
TemplateDeclaration:
template TemplateIdentifier ( TemplateParameterList ) Constraintopt {
DeclDefs }
And, TemplateParameterList is defined as:
TemplateParameterList:
TemplateParameter
TemplateParameter ,
TemplateParameter , TemplateParameterList
TemplateParameterList must consume one or more TemplateParameter, so we cannot
declare zero-arg template declaration!
Of course it is possible with current compiler, so it's a grammar bug.
Same problem is in TemplateMixinDeclaration.
Also, template instantiation grammar has similar problem.
TemplateArgumentList must consume one or more arguments, so TemplateMixin and
TemplateInstance cannot take zero arguments.

Moreover, DeclarationSuffix had been wrong, because TemplateParameterList does not have both side parenthesis. https://github.com/D-Programming-Language/d-programming-language.org/commit/8de780bf1457fd8c9eca9e683cd6bb25fa140418 Issue 9503 - [grammar] template declaration/instance must take one or more arguments? -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
