kandi X-RAY | ast Summary

ast is a Rust library typically used in Utilities, Parser applications. ast has no bugs, it has no vulnerabilities and it has low support. However ast has a Non-SPDX License. You can download it from GitHub.

This is an in-development add-on to the pest parsing library. Pest-ast provides a structured manner to go from the "dynamically typed" Pest Parse Tree to a strongly typed (Abstract) Syntax Tree, as well as a derive to do so automatically. In the future, it's planned to optionally additionally check the source grammar to statically prevent issues that are currently detected at runtime. In the future , pest-ast may provide a way of defining grammar directly on the AST nodes.

            Folding indexed functors with access to contextual data
            Asked 2022-Apr-01 at 22:53

            This is a question about traversing mutually recursive data types. I am modeling ASTs for a bunch of mutually recursive datatypes using Indexed Functor as described in this gist here. This works well enough for my intended purposes.

            Now I need to transform my data structure with data flowing top-down. here is an SoF question asked in the context of Functor where it's shown that the carrier of the algebra can be a function that allows one to push data down during traversal. However, I am struggling to use this technique with Indexed Functor. I think my data type needs to be altered but I am not sure how.

            Here is some code that illustrates my problem. Please note, that I am not including mutually recursive types or multiple indexes as I don't need them to illustrate the issue.

            setDepth should change every (IntF n) to (IntF depth). The function as written won't type check because kind ‘AstIdx -> *’ doesn't match ‘Int -> Expr ix’. Maybe I am missing something but I don't see a way to get around this without relaxing the kind of f to be less restrictive in IxFunctor but that seems wrong.

            Any thoughts, suggestions or pointers welcome!

            I'm assuming here that you're trying to set each IntF node to its depth within the tree (like the byDepthF function from the linked question) rather than to some fixed integer argument named depth.

            If so, I think you're probably looking for something like the following:

            How do I get mobile status for discord bot by directly modifying IDENTIFY packet?
            Asked 2022-Feb-09 at 15:05

            Apparently, discord bots can have mobile status as opposed to the desktop (online) status that one gets by default.

            After a bit of digging I found out that such a status is achieved by modifying the IDENTIFY packet in discord.gateway.DiscordWebSocket.identify modifying the value of $browser to Discord Android or Discord iOS should theoretically get us the mobile status.

            After modifying code snippets I found online which does this, I end up with this :

            ANSWER

            Answered 2022-Feb-07 at 23:03

            The following works by subclassing the relevant class, and duplicating code with the relevant changes. We also have to subclass the Client class, to overwrite the place where the gateway/websocket class is used. This results in a lot of duplicated code, however it does work, and requires neither dirty monkey-patching nor editing the library source code.

            However, it does come with many of the same problems as editing the library source code - mainly that as the library is updated, this code will become out of date (if you're using the archived and obsolete version of the library, you have bigger problems instead).

            It doesn't have any result on how the macro is used, it only serves to improve the quality of error messages when the macro is used incorrectly by telling the compiler that the output of the macro is always a single expression, not an item or multiple expressions.

            The specific error that this was added to improve was for using vec![] in a pattern match, which is invalid (you can't structually match on a Vec):

            Forking core eslint rules
            Asked 2021-Nov-26 at 17:09

            I want to do some minor edits to core eslint rules, e.g. array-bracket-newline, or indent. These rules often depend on utilities inside eslint, most commonly ast-utils. So far, i've used a plugin, added the modified rules there, and did a require('eslint/lib/rules/utils/ast-utils'), as eslint is a peer-dependency anyways.

            Since https://github.com/eslint/eslint/commit/24c9f2ac57efcd699ca69695c82e51ce5742df7b this is no longer possible, as an exports directive was added to the package.json. What is the usual method for changing behavior of core eslint rules nowadays?

            • copying out all dependencies would be possible, but both tedious, and duplicating code for no reason (i'd have to trace all the dependencies, and rip out chunks of eslint's code).
            • forking eslint as a whole seems unclean, as there are a lot of other parts, which depend on it (starting from eslint-plugins, over to vscode extensions, yarn sdks, ...). Each one would need to be changed, or some very dirty rename used, in which the fork pretends to be the original (accident waiting to happen).
            • yarn package patching the exports away seems really dirty.

            Is there some clean way?

            Edit: my current best idea is forking eslint, removing the exports, and then using require('eslint-fork/lib/rules/utils/ast-utils') on the fork. This means i need an extra eslint copy for no real reason, but it's for linting, and a bit of disk space isn't important.
