- Added a default c-tor to the input stream to avoid an ambiquity.
- Changed the input stream API so that it can take a string pointer + length and use that for UTF conversion, avoiding so unnecessary copies. Convenience methods exist to use a std::string or a std::string_view.
- With that only a single load() method is necessary.
- In ANTLRFileStream the other c-tors are now also deleted, as they make no sense there.
A previous change to add std::string_view support to ANTLRInputStream for C++17 caused some trouble because of ABI changes. This has been changed to define 2 constructors, one for std::string_view (for C++17) and the original one for std::string.
This is turn caused an error in ANTLRFileStream, which also takes a string in the constructor (but handling it as file name instead of input). To make this clearer the c-tor taking a std::string has been deleted in ANTLRFileStream and the class now requires to load input via the loadFile() function. This might cause some trouble for those users who had used the std::string constructor of ANTLRFileStream, but I think the better error reporting outweighs the little annoyance.
* Fixes for https://github.com/antlr/antlr4/issues/2693
* Adding script for comparing Java and C# profile output.
* Update lexer grammar.
Tightening up the grammar rules. Still Java9.
* Tighten up grammar.
* Adding in new base classes for C# runtime tests for profiling.
* Complete test for Profile = true.
Update ProfileDescriptor to now parse and output profile. The grammar is asm8080 from grammars-v4, tightened up. The input is the example provided there, truncated to included fewer lines as that causes a null-ptr crash with the older runtime. I verified by modifying the .csproj in /tmp.
* Restructuring the Antlr C# runtime so that it is consistent with all other runtimes, a source directory (now antlr4/runtime/CSharp/src), and a test directory (antlr4/runtime/CSharp). In the test area, I added a test for profiling in issue-2593. This test requires the Antlr tool and Antlr C# tool to be build. The path is assumed in a relative path to the test, ../../../../tool/target/antlr4-*-SNAPSHOT-complete.jar, with globbing performed. The test simply checks the return result, output not important. There are no changes to the runtime C# source files other than placing them under src/. Several other build files were changed to reflect the new location of the Antlr C# runtime. I updated the instructions for users on how to build the runtime, including information on checking the environment--now explicitly specified here so people know what to install!
