[stringtemplate-interest] C# updates for ANTLR 3.4, StringTemplate 4.0.4

[Sam Harwell]

I missed that the methods in TreeFilter and TreeRewriter have different
signatures. I believe they should either both be protected or both be public
- which is it (are they supposed to be called directly by external code)?

 

For now, you can change the following two rules in CSharp3.stg from this:

 

ruleWrapperBottomup() ::= <<

<if(TREE_PARSER && filterMode)>

public override IAstRuleReturnScope Bottomup() { return bottomup(); }

<endif>

>> 

 

ruleWrapperTopdown() ::= <<

<if(TREE_PARSER && filterMode)>

public override IAstRuleReturnScope Topdown() { return topdown(); }

<endif>

>> 

 

 

To this:

 

ruleWrapperBottomup() ::= <<

<if(TREE_PARSER && filterMode)>

<if(buildAST)>public override IAstRuleReturnScope<else>protected override
void<endif> Bottomup() { return bottomup(); }

<endif>

>> 

 

ruleWrapperTopdown() ::= <<

<if(TREE_PARSER && filterMode)>

<if(buildAST)>public override IAstRuleReturnScope<else>protected override
void<endif> Topdown() { return topdown(); }

<endif>

>>

Sam,

 

Apparently, the TreeFilter class defines Topdown() and Bottomup() as
protected void, but the overrides are defined as public IAstRuleReturnScope.
When building my parsers using the new release, I get the following errors
(sorry, text-only folks):

 



 

Thanks,

Kevin

Hello everyone,

 

I just finished updating the C# ports of ANTLR and StringTemplate for the
recent releases of ANTLR 3.4 and StringTemplate 4.0.4. This is a significant
update for the C# port, and includes the following in addition to the
updates found in the corresponding Java versions.

 

.         The CSharp2 target has been updated to use the same runtime
assembly as the CSharp3 target (Antlr3.Runtime.dll).

.         Tree grammars with "filter=true" now automatically generate the
required overridden implementations of TreeFilter.Topdown and/or
TreeFilter.Bottomup.

.         Improved support for delegate grammars in the build process (set
their Build Action to AntlrAbstractGrammar and Custom Tool to
MSBuild:Compile).

.         Improved Tool performance.

 

The documentation and downloads can be found at the following page:

http://www.antlr.org/wiki/display/ANTLR3/Antlr3CSharpReleases

 

Also, if you end up using (and liking) my Visual Studio 2010 extensions, I
appreciate the reviews on the Visual Studio Gallery. :)

 

Thank you,

Sam Harwell
