Question about parsing ASTs using Boa

[Yiming Tang]

Dear Boa users,

I've looked at the examples on the website (http://boa.cs.iastate.edu/examples/index.php) but didn't find one that could parse ASTs.  Is it possible to parse (possibly partial) ASTs from git commits using Boa?

Thanks a lot!

Best regards,

Yiming Tang

Hi Yiming,

The dataset already has parsed ASTs and provides them with our custom data types (http://boa.cs.iastate.edu/docs/dsl-types.php).  This occurs currently for Java files.

In the case of files that had parse errors, I believe we keep whatever partial AST the Eclipse JDT parser provided us and we mark those nodes as SOURCE_JAVA_ERROR kinds.

Boa does not provide support for parsing any other data in the dataset, or manually parsing the Java data (as we already have parsed it all).

Dear Robert,

Thank you so much.

Sorry, I didn't say it clear. My focus is "parse (possibly partial) ASTs from git commits using Boa".  Specifically, I would like to know if AST information is available from commit diffs by using Boa. 

Best regards,

Yiming

As I mentioned, an AST is available for all Java source files in each revision.

If you need a diff between revisions, there is currently no diff support and you would have to compute one with your own query.
