You have to explicitly enable support for enums in. The only caution I would suggest is to make sure that you don't add non-literal types to your enum unions, because that will cause our optimizations to fail and leave you with the worst case peformance. 450 variants is really not that large in the scheme of things we deal with unions with upwards of 100,000 elements routinely. Luckily we have a lot of optimizations in place for dealing with unions, especially those that can be simplified to enums (unions of strings or number literals). Where this gets really bad is when we compare two union types, and this can easily result in an exponential case where we need to perform a lot of work for every single combination of union cases. If the union isn't actually a supertype we end up needing to check every case. To determine if a union is a valid subtype of another type, we need to consider whether every single element of the union is a valid subtype, while to determine if it's a supertype we need to check if at least one of its cases is a supertype. Essentially the reasons large unions are slow is that the amount of work Flow needs to do can grow exponentially with the size of the union. I've been working on this recently so I can give you an overview. Performance of Large unions (simple enums) In short, restrictive type systems drive programmers to more flexible environments. Programmers dislike having the computer reject a program that would have run fine, simply because the computer couldn’t make sure it would run fine without actually running it. Please note: not everything can be expressed/modeled in your type system so you have to take into account also dynamic errors (division by zero or integer overflow) when writing your program. ![]() For example, if an expression’s static type is string, at runtime, you are guaranteed only to get a string when you evaluate it. Which to pick?Ī sound type system is one that ensures your program does not get into invalid states. A complete type system accepts all valid programs, and some invalid ones to boot. complete Ī sound type system (or analysis) is one that rejects all erroneous programs, and a complete system accepts all correct programs.Ī sound type system is one that is not lenient, in that it rejects all invalid programs plus some number of valid programs. near the beginning of the year we also made it so that the oncall is responsible for addressing libdef and documentation PRs, since there is usually no clear owner for those, and pretty much anyone should be able to review themįlow exited with some numeric exit code and you are not sure what does it mean? You can find these exit codes here: Sound vs. it's relatively calm as oncalls go (we aren't getting woken up in the middle of the night), but whoever is oncall is responsible for doing support (we have an internal group where people can ask questions), and also responsible for taking the lead if something goes wrong with Flow or the various related integrations we have. Last year I reviewed new features first, and then trends. The reasons for that have become even clearer over the past year. This year Adobe doubled down on all three of those themes. So the way it works is that the Flow team has a rotating oncall. When I covered MAX last year, I noted that three of the themes driving new features were collaboration, creativity, and machine learning. ![]() If you don't want inference to widen your type, the solution is always to annotate. ![]() ![]() Your authors and editors are no longer “frozen out” once layout begins.Flow infers the widest type that makes your code work. So you can format, layout, and edit in InDesign, while your authors and editors continue creating and editing story content together in real time using Google Docs documents, all without ever losing work. DocsFlow lets you place online Google Docs documents as InDesign story contents, just like normal text files. The Pro version provides a two-way link so you can push your InDesign story changes back to Google Docs. More importantly, DocsFlow maintains a dynamic link so it can intelligently merge Google Docs changes into the InDesign story contents on each link update, rather than just replacing the story. (You can also place by dragging and dropping files from Google Drive.) DocsFlow, a plug-in for InDesign, for the first time combines the collaborative editing power of Google Docs with the layout power of InDesign, adding its own dynamic linking and sophisticated merge technologies to supercharge your editorial and production workflows.ĭocsFlow Place menuWith DocsFlow, you place online Google Docs documents (including tables and graphics) and spreadsheets (Pro version) as InDesign story contents, just like normal text or spreadsheet files.
