This is based on the MLIR opt kernel: https://github.com/llvm/llvm-project/tree/main/mlir/utils/jupyter The inent of this is to enable experimentation and the creation of interactive tutorials for the basics of tablegen. Noteable changes from that: * Removed the codemirror mode settings since those won't exist for tablegen. * Added "%args" "magic" to control arguments sent to llvm-tblgen. (magics are directives, see https://ipython.readthedocs.io/en/stable/interactive/magics.html) For example the following: ``` %args --print-detailed-records class Stuff {} def water_bottle : Stuff {} ``` Produces: ``` DETAILED RECORDS for file - -------------------- Global Variables (0) -------------------- -------------------- Classes (1) -------------------- Stuff |<stdin>:1| Template args: (none) Superclasses: (none) Fields: (none) -------------------- Records (1) -------------------- water_bottle |<stdin>:3| Superclasses: Stuff Fields: (none) ``` Reviewed By: jpienaar, awarzynski Differential Revision: https://reviews.llvm.org/D132378
