kandi X-RAY | emscripted-ruby Summary

emscripted-ruby is a JavaScript library typically used in Utilities, Transpiler applications. emscripted-ruby has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Emscripted Ruby is a build script that uses [Emscripten] to compile Ruby MRI 1.8.7 for use in a browser. The main difference is the conversion from C to C and the switch from setjmp/longjmp (which can’t be implemented in JavaScript) to C exceptions. Note that we are not using Ruby 1.9.x due to its reliance on threads, which cannot be ported directly using Emscripten. The project is fairly young. Right now it suffers from a memory leak due to a bug in the emscripting of the Ruby garbage collector. The performance is also a problem, as so far we’ve enabled runtime checking of all signing and overflow issues. Switching to just the needed sign/overflow corrections should boost performance significantly. The build script is licensed under the [MIT license] The modifications follow Ruby’s GNU GPL2 license.

            This is a design limitation in TypeScript; see microsoft/TypeScript#46707 for details. It's sort of a cascading failure that results in some weird errors.

            A generally useful feature was implemented in microsoft/TypeScript#29478 allowing the compiler to use the expected return type of a generic function contextually to propagate a contextual type back to the generic function's arguments. That might not make much sense, but it sort of looks like this:

            babel-maven-plugin not transpiling spread operator to ES5
            Asked 2021-Nov-30 at 15:39

            I am using DOJO toolkit and after upgrading to use the closure compiler, I noticed I needed to transpile to ES5 BEFORE the dojo build util does it's job in order to take advantage of newer ES6+ features.

            So I am using babel-maven-plugin to accomplish this.

            Everything is working fine with the exception that the ...spread operator is not transpiling.

            Do I need to download the @babel/preset-env package as well to set the preset option? or is there an option I am missing?

            ...

            ANSWER

            Answered 2021-Nov-30 at 15:39

            After further discovery there is no need to download any preset package.

            babel-standalone takes in preset options through its API as defined here and use in the babel-maven-plugin here.

            The preset option is not passed to the Babel API like defined in a .babelrc config file. It is passed in without the preset- prefix. So to get the @babel/preset-env preset option you need to simply pass in env.

            So to round this out, here are the common presets and how you would pass them through to the API:

            • @babel/preset-env --> env
            • @babel/preset-react --> react
            • @babel/preset-flow --> flow
            • @babel/preset-typescript --> typescript

            So in order to use babel-maven-plugin I need to set up the pom.xml as follows:

            Writing a transpiler is a very big job... For a variety of reasons, though, JavaScript workflows are already full of transpilers, so there are many tools to help.

            If your target language looks like JavaScript, then you would write your transpiler as a plug-in for Babel: https://babeljs.io/

            Otherwise, maybe start with jscodeshift, which will provide you with an easily accessible AST.

            Many open-source javascript tools, like eslint, also have javscript parsers in there that you could extract with a bit of effort.

            Also see the AST Explorer

            Once you have an AST, you would typically process it recursively, maybe following the visitor pattern, to convert each AST node into the equivalent target structure. Then maybe peephole optimization to simplify the resulting AST. Then finally serialize it. jscodeshift comes with a javascript serializer that you could replace with your own.

            Transpiling node-fetch require returns error
            Asked 2021-Nov-12 at 22:59

            I'm running into an issue with the node-fetch library. The new version (3.0.3) has "type": "module" in its package.json. This is a problem because I transpile my code from ES6 to regular js which uses require and then I get ...firebase_datasource.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. I can use an earlier version of node-fetch that doesn't contain "type": "module" in its package.json in its package.json, but that's not a solution. What's the correct way to handle this?

            CommonJS

            node-fetch from v3 is an ESM-only module - you are not able to import it with require().

            If you cannot switch to ESM, please use v2 which remains compatible with CommonJS. Critical bug fixes will continue to be published for v2.

            Is this transpilation issue correctly filed against babel-jest?
            Asked 2021-Jun-03 at 17:14

            I raised an issue https://github.com/facebook/jest/issues/11504 against the jest project, which I think is responsible for maintaining babel-jest. Transpilation totally fails after adding apparently harmless and error-free code.

            However, there are a lot of layers to the transpilation of a Typescript Next project, so I am unsure if this is the correct place to file the issue and matches with the likely source of the failure.

            Does this issue seem like it matches with the babel-jest project or should I file it somewhere else?

            BUG

            I found in a complex Next Typescript project that adding a handful of lines in one file was enough to break babel-jest transpilation and create runtime errors in a completely different file.

            In commit 04c4c7b, after checking out the clean project and running yarn I am able to get passing tests with yarn run test. The passing source tree is at https://github.com/cefn/jest-transpile-failure-repro/tree/04c4c7b7013e8b88c25d3ab2a7d4a33ccd3fb191

            However, after adding the handful of lines which you can see in commit 25703fc the babel-jest transpiler seems to effectively break making tests impossible to run, and a totally unrelated file starts to get runtime errors during the test which make no sense like...

            I want to be very clear that I am not asking how to transpile a C# UWP app to a JavaScript UWP app. I am, rather, attempting to extract portions of an existing C# UWP application that can be migrated to create a Node.js server.

            The latest pre-built files are found in the dist folder:. If you want to build it manually, run ./makeruby. If you want to use the Closure Compiler, you will need to check out and build a recent version, then provide the path to it in makeruby. That script also contains a few configurable options. You might need to tweak RELOOP, PREINITIALIZED_MEMORY and RUN_CLOSURE until you get optimal performance in all your target browsers. For the manual build, you will need to have Emscripten and Emmaken configured as per the Emscripten documentation.
            ruby.js is the raw human-readable compiled source produced by Emscripten.
            ruby.opt.js is the human-readable compiled source after being passed through the redundant variable elimination script.
            ruby.closure.js is ruby.opt.js after being passed through the Closure Compiler. This is what you will likely want to use.
            lib is the folder containing the Ruby standard library. You will want to copy this alongside one of the above JavaScript files to your app.
