Transpile anything to everything!
To cure this pain, we wanted to allow users to export the queries they built-in Compass into whatever programming language they wanted. Even better, we wanted to also allow users to write their favorite language directly into Compass. To achieve these goals, we needed a way to translate query syntax in any programming language into query syntax in any other language, so we needed to write a multi-language-input to multi-language-output transpiler!
This talk will go through the technical design of the anything-to-anything pluggable transpiler and teach attendees how they can add their own favorite language to Compass. Anna will talk about classic compiler design principles and how she leveraged various compiler technologies to create a dynamic, extensible transpiler. Lastly, she'll talk about how we can take this transpiler and apply it to an abundance of other use cases!
Anyone with an interest in compilers, parsers, Compass, MongoDB, ANTLR, or a general passion for complex technical problems is welcome. Anna will talk about classic compiler design without requiring attendees to be programming-language experts, although any knowledge of compiler implementations will be useful. Attendees will leave the talk knowing exactly how to extend Compass to support new languages and will hopefully be inspired to go out and add their favorite language to Compass!
This talk addresses both MongoDB-specific challenges as well as highly technical computer science problems. Attendees will learn not only about Compass itself but about compiler design. As developers, we use compilers every day, but it is not so often that we get the opportunity to actually write them, and compilers are awesome!
Anna Herlihy is a senior software engineer working for MongoDB in Stockholm. She is a contributor to PyMongo, MongoDB, bson-numpy, and a few other MongoDB Drivers but is working now on Compass, the GUI for MongoDB. She enjoys hiking, biking, climbing, and is most happy when she can do her work outdoors.
