使用Antlr-3.5-complete.jar生成OracleSQL语法的大量模板错误

时间：2013-03-22 19:22:14

标签： antlr3

使用Antlr-3.3-complete.jar生成相同的oracle SQL语法而没有错误，并使用Netbeans / GCC或Visual Studio成功编译。

使用Antlr-3.5-complete.jar生成语法会生成23500行警告消息，描述模板错误，包括几百个例外。

使用以下命令行生成代码：

java -d64 -Xmn2000M -Xmx8000M -jar antlr-3.5-complete.jar OracleSQL_v2.g

antlr-3.5-complete.jar于2013年3月22日从antlr.org网站下载。

该语法基于Ivan.Brezina发布的antlr.org网站上的Oracle PL / SQL语法。

生成的代码有282个未声明的标识符。在生成的解析器synpred子例程中，许多$tokenRef个变量未声明。此外，生成的词法分析器有100个

由于3.5之前的版本中存在错误，因此无意中禁止了这些消息。某些目标已更新以更正问题，但您似乎正在使用尚未更新的目标（您未指定）。

另请注意，有关模板错误的消息是警告消息，而不是错误。您的输出仍应生成。

你能发布一个小例子来重现编译错误吗？

答案 1 :(得分：0)

我有同样的错误。语法取自http://www.antlr3.org/grammar/list.html

重现错误的所有方法是下载，提供antlr-3.4-complete.jar（修改Makefile）而不是附加antlr-3.3-complete.jar并运行Makefile。

处理语法时出现很多警告错误。但是生成的输出源文件无法编译，因为ANTLR 3.4和3.5生成如下行：

void ;
#undef RETURN_TYPE
#define RETURN_TYPE void

打字 

grep undef.*RETURN_TYPE OracleSQLParser.c | nl
显示使用模板C.stg正确填充了前1135个案例。从1136到生成源的结束，所有出现的内容都由void填充。

当我将输出从C目标切换到java时，没有看到错误。

答案 2 :(得分：0)

我遇到了关于“未声明的_empty”的相同问题。 我找到的最简单的例子是：

foo: ( 'A'+ 'B' )+ 'A'+ ;

（这个错误案例似乎与＃34; Cyclic DFA＆＃34;模式有关。但我不明白它的真正含义。）

ANTLR 3.5.1生成解析器源，如：

static const ANTLR3_INT32 * const dfa2_transitions[] =
{
    dfa2_T1, dfa2_T0, _empty, _empty
};

这会导致未声明的＆＃34; _empty＆＃34;的编译错误。

在那之前，我找到了：

/** Used when there is no transition table entry for a particular state */
#define dfa2_T_empty        NULL

我想＆＃34; _empty＆＃34;应该是＆＃34; dfa2_T_empty＆＃34;在生成的代码中。

我目前在语法文件中加入了快速解决方法。但我不确定这在运行时是否正常。

@header {
   #define _empty NULL
}
