unfortunately i need this interface, otherwise I can't reset the warning buffer between multiple runs

Not sure if there's a way to do conditional rules to add the playground snapshot build

@cristianoc compilation performance should be generally good, so running this with every ninja build feels like the right thing to do. Also the jsoo_main entrypoint is identical from a dependency perspective and always has been part of the build process ever since.
Note: The slowest part of building the playground is running jsoo with scripts/repl.js, and we'd probably want to set up a CI job later to automate / test the bundle build process. We don't need to run this compilation on a regular basis since JSOO is quite reliable as long as the ocaml code compiles.

Looks like the differences are absorbed by measurement noise, so nothing of note there.

Looks like json_refmt_main.ml has been deleted in this diff. Is some of this file stale?

ah yes I renamed that file bc refmt is gone. Will update.
For reference on the previous work in 2020, refer to #4518
Configure the parser to pass forPrinter:true when parsing / printing ReScript. This fixes issues where e.g. Some((1, 2)) get misprinted to Some(1,2) etc. Relevant bug reports: - rescript-lang/syntax#274 - rescript-lang/syntax#265

* Add all relevant changes from previous 2020 bundle API For reference on the previous work in 2020, refer to rescript-lang#4518 * Add ninja rule for building jsoo_refmt_main * Fix formatting edge-cases when formatting ReScript -> ReScript Configure the parser to pass forPrinter:true when parsing / printing ReScript. This fixes issues where e.g. Some((1, 2)) get misprinted to Some(1,2) etc. Relevant bug reports: - rescript-lang/syntax#274 - rescript-lang/syntax#265 * Introduce initial type hints in playground bundle results * Adapt playground to newest internal syntax apis * Make jsoo_refmt_main work again by removing refmt * Rename jsoo_refmt_main to jsoo_playground_main * Move jsoo_playground_main to jscomp/main * Remove irrelevant code * Remove Refmt_api * Make repl.js more reliable with missing .mli files * repl.js: Log target compiler file, set js_playground_main as default * Update CONTRIBUTING to align with the renamed playground jsoo entrypoint Co-authored-by: Patrick Stapfer <[email protected]>
Continuing the work of #5079. Here are the main changes:
Refmt_apiand somesrc/ast_406.mltype mismatches)repl.jsfile to allow compilation of different JS bundle versions (by default it will compile thejs_compilebundle)Note on the
refmtthing: I guess the only way to re-introduce refmt support would be via a separate bundle. Basically like in the good old BuckleScript playground times.The lack of refmt support eliminates half of the playground code though, so from a maintenance perspective it's way easier now.
