Amele is a command-line tool I wrote yesterday to convert EF6 attribute based Index definitions into EF Core ModelBuilder based notation.
It's extremely primitive, and probably very buggy but it worked fine for me. I think I barely missed the mark for spending more time than doing the actual menial work (relevant XKCD).
I used the brilliant System.CommandLine.DragonFruit package to handle command-line parameters, it's so convenient. I love it. It's not for more complicated tasks obviously. In that case System.CommandLine still provides good amount of luxury. Check them out.
To test it on a single EF6 entity file that contains [Index(..)]
attributes:
amele --input C:\Project\Db\MyEntity.cs
It will provide the output to the console. If you want to process whole directory:
amele --input C:\Project\Db --output C:\Project\Output.cs
The output file will be overwritten, and you'll have to extract code from it.
I think projects migrating from EF6 that are using [Index] attributes extensively might
benefit from the conversion work by using a tool like this. But I appreciate if you provide
your modifications so this can evolve into something useful to a broader audience.
Potential improvements:
- Unit tests
- More flexible regexes
- Use Roslyn instead of regexes for full reliability
