Adds a json::Expr type to represent intermediate JSON expressions. Summary: This form can be created with a nice clang-format-friendly literal syntax, and gets escaping right. It knows how to call unparse() on our Protocol types. All the places where we pass around JSON internally now use this type. Object properties are sorted (stored as std::map) and so serialization is canonicalized, with optional prettyprinting (triggered by a -pretty flag). This makes the lit tests much nicer to read and somewhat nicer to debug. (Unfortunately the completion tests use CHECK-DAG, which only has line-granularity, so pretty-printing is disabled there. In future we could make completion ordering deterministic, or switch to unittests). Compared to the current approach, it has some efficiencies like avoiding copies of string literals used as object keys, but is probably slower overall. I think the code/test quality benefits are worth it. This patch doesn't attempt to do anything about JSON *parsing*. It takes direction from the proposal in this doc[1], but is limited in scope and visibility, for now. I am of half a mind just to use Expr as the target of a parser, and maybe do a little string deduplication, but not bother with clever memory allocation. That would be simple, and fast enough for clangd... [1] https://docs.google.com/document/d/1OEF9IauWwNuSigZzvvbjc1cVS1uGHRyGTXaoy3DjqM4/edit +cc d0k so he can tell me not to use std::map.

Adds a json::Expr type to represent intermediate JSON expressions. Summary: This form can be created with a nice clang-format-friendly literal syntax, and gets escaping right. It knows how to call unparse() on our Protocol types. All the places where we pass around JSON internally now use this type. Object properties are sorted (stored as std::map) and so serialization is canonicalized, with optional prettyprinting (triggered by a -pretty flag). This makes the lit tests much nicer to read and somewhat nicer to debug. (Unfortunately the completion tests use CHECK-DAG, which only has line-granularity, so pretty-printing is disabled there. In future we could make completion ordering deterministic, or switch to unittests). Compared to the current approach, it has some efficiencies like avoiding copies of string literals used as object keys, but is probably slower overall. I think the code/test quality benefits are worth it. This patch doesn't attempt to do anything about JSON *parsing*. It takes direction from the proposal in this doc[1], but is limited in scope and visibility, for now. I am of half a mind just to use Expr as the target of a parser, and maybe do a little string deduplication, but not bother with clever memory allocation. That would be simple, and fast enough for clangd... [1] https://docs.google.com/document/d/1OEF9IauWwNuSigZzvvbjc1cVS1uGHRyGTXaoy3DjqM4/edit +cc d0k so he can tell me not to use std::map.
