1. © 2006 by «Author»; made available under the EPL v1.0 | Date | Other Information, if necessary Doug Schaefer My plans/dreams for C# in CDT

2. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 2 Why C#  Needed to prove multi-language capabilities  Fortran already being done and I don’t really know Fortran  Ada is a great language but use is on decline  Java already done with JDT  C# very popular in Windows circles  Mono project bringing C# other platforms, especially Linux  C# (IMHO) is a better Java  Operator overloading  Structs – inline object store  Easy integration to native methods

3. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 3 Why C# - Ulterior motives  Eclipse Foundation very excited about this project  A path to bring Windows developers into Eclipse world  Helps the cause of Eclipse as valid alternative to VisualStudio  There is nothing VisualStudio does that can’t be done in Eclipse  Takes member commitment, though.  Help grow the CDT community as well  More users mean more testers  And the odd developer  High profile project could mean more commercial interest  Thus even more developers

4. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 4 What components are needed?  ILanguage implementation for Core Models  ILanguageUI implementation for Editor adaptation  Compiler Integration for building  Debugger Integration for debugging  In theory, that should be it

5. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 5 ILanguage  New DOM implementation  Extend IAST interfaces for AST  Extend IBinding and IType for semantic info  Extend PDOM classes for index  C# Scanner and Parser  Using ANTLR v3 to expedite  Need sharable preprocessor  Reusable with other ANTLR based parsers (others?)  CModelBuilder needed too  Extend ICElement interfaces, build using DOM

6. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 6 ILanguageUI  Right now only have new code scanner  Clone of C++ scanner  Different keywords, types, constants  Many other things should be same  May want to override editor menu to remove items

7. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 7 Compiler Integration  C# compilers different than C/C++ compilers  No object code, direct source to DLL/EXE  No linker  Need to compile all files producing the build target in one command invocation.  Not a lot of command line options  But does do debug versus release (i.e. configs needed)  Debating my own builder versus managed make  Independent contributor is looking at managed make  Microsoft (csc) and Mono (mcs) compilers very similar

8. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 8 Debugger Integration  Windows and Mono very different here, need different solutions  Windows – C++ COM interfaces to debugger APIs  Mono – young (0.20) written in C#  Maybe later…  How to hook up Windows debugger  CDI layer that uses JNI to talk to debugger API  DSF instead of CDI?  Separate executable that talks MI to CDT a la gdb

9. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 9 Debugger Integration  MI seems to be safer alternative  Out of process, won’t bring down Eclipse if it crashes  Can test from command line  Use similar architecture for C++ debugging on Windows  Which will use dbghelp APIs (similar architecture to.Net)  Build reusable MI library in C++  EPL for all to use/contribute to  Using CDT, of course!  But how do you debug your debugger…

10. Presentation Title | Presentation Subtitle | © 2006 by «Author»; made available under the EPL v1.0 10 Who’s working on it?  This is where plan turns into dream   Or, how to build a community from scratch.  Already have one independent guy working in personal time  Myself very part time  The hope is, as it starts to materialize, interest will spike  Start making noise about it in developer forums  Mono  Even Microsoft C# forums  Mentioned in my Podcast for EclipseZone
