    feat: default to non-capture, add `grouped` and `groupedAs`

    last updated: 2022/8/17

    1. Update all creation and chaining helper inputs with anonymous capturing group syntax to non-capturing group by default.

    updated inputs:

    • creation inputs: anyOf, maybe, oneOrMore
    • chaining inputs: or, times(.between/atLeast/any), optionally

    1. Add chaining input helper grouped to opt-in/capture anonymous group.

    2. Add chaining input helper groupedAs to capture named group, same functionality as original as. and make as as an alias to groupedAs

    Usage

    // chaining with `.grouped`
const defulatToNonCapture = anyOf('foo', 'bar') // Input<"(?:foo|bar)", never>
const capture = anyOf('foo', 'bar').grouped() // Input<"(foo|bar)", never>

const group = exactly('foo').times.between(2,5).grouped() // Input<"(foo){2,5}", never>

  • fix: can't import transform in vite project without `type: module`

    fix: can't import transform in vite project without `type: module`

    🐛 The bug

    When I try to use magic-regexp in a Laravel + Vite project I get the following errors:

    Error [ERR_REQUIRE_ESM]: require() of ES Module /home/hassan/project/node_modules/.pnpm/[email protected][email protected]/node_modules/magic-regexp/dist/transform.mjs not supported.

    🛠️ To reproduce

    You can easily reproduce by following these steps:

    laraven new
npx @preset/cli apply laravel:inertia
php artisan serve
npm run dev

    When you add the vite plugin, you will see the dev command will fail with error.

    🌈 Expected behaviour

    I expect it to work based on the project readme instructions and code examples.

  • feat: implement `letter.lowercase` and `letter.uppercase`

    feat: implement `letter.lowercase` and `letter.uppercase`

    Pretty trivial implementation!

    However, something is wonky in the changes to the typings tests I introduced in c2200a478fbceb25fcd88f274e064ab7068c9acb... The tests were broken by introducing lowercase and uppercase properties to letter, and when I tried reproducing a minimal example of it on typescriptlang.org, of course there, an Asdf<T> & { yes: 'no' } does extend Asdf<any>. I couldn't put my finger on what the fix should be.

    There might be a better way to handle them through savvy typing of the extractRegExp function, but I couldn't figure it out myself. 🙇‍♀️

    Resolves #37.

  • fix: update interface `Input` type parameter to contravariant type

    fix: update interface `Input` type parameter to contravariant type

    Updates

    1. Add in contravariant annotation to type parameter V of Input type:
    interface Input<
-  V extends string,
+  in V extends string,
  G extends string = never,
  C extends (string | undefined)[] = [] > { ... }
    1. Refactor InputSource to make Input accept any V type as it is set as contravariant type:
    - export type InputSource<S extends string = never, T extends string = never> = S | Input<S, T>
+ export type InputSource<S extends string = string, T extends string = never> = S | Input<any, T>
    1. Update/refactor IfUnwrapped type's all parameters to extends string instead of Input (makes usage more concise)
    - any: () => IfUnwrapped<V, Input<`(?:${V})*`, G>, Input<`${V}*`, G, C>>
+ any: () => Input<IfUnwrapped<V, `(?:${V})*`, `${V}*`>, G, C>
    1. fix ts comments for and and times chaining Input helpers

    Note

    This PR should resolve the type inferencing issue (using extractRegExp helper or directly using createRegExp) when implementing new letter.lowercase and letter.uppercase helper inputs in PR #77 and any future implementations of similar input helpers design to be accessed by `dot notation.

    ⭐ What is New?
    🔰 Security Fixes

    This release contains multiple security related fixes #​8675, #​8674 and #​8673 reported via huntr.dev platform by OhB00.

    We recommend you upgrade to the latest version as soon as possible.

    If you encounter "The request URL ... is outside of Vite service allow list" issue, try adding path to vite.server.fs.allow in nuxt.config. read more.

    🚀 Performance Improvements

    Using a new method to extract definePageMeta improves vite performance and makes lazy compilation of pages possible (#​8536).

    💯 Strict Config Schema and Types

    We have cleaned up the configuration schema (#​8487) so that you no longer would be confused with Nuxt 2 options and also can quickly notice any typos in nuxt.config file.

    Typescript strict mode is also enabled by default with this release as best practice. (#​8667)

    🚇 Nitro Development Server Proxy

    Using nitro.devProxy option you can now configure proxies for the development server. (learn more)

  • ci: add codeql code scanning workflow

    ci: add codeql code scanning workflow

    Hi danielroe/magic-regexp!

    This is a one-off automatically generated pull request from LGTM.com :robot:. You might have heard that we’ve integrated LGTM’s underlying CodeQL analysis engine natively into GitHub. The result is GitHub code scanning!

    With LGTM fully integrated into code scanning, we are focused on improving CodeQL within the native GitHub code scanning experience. In order to take advantage of current and future improvements to our analysis capabilities, we suggest you enable code scanning on your repository. Please take a look at our blog post for more information.

    This pull request enables code scanning by adding an auto-generated codeql.yml workflow file for GitHub Actions to your repository — take a look! We tested it before opening this pull request, so all should be working :heavy_check_mark:. In fact, you might already have seen some alerts appear on this pull request!

    Where needed and if possible, we’ve adjusted the configuration to the needs of your particular repository. But of course, you should feel free to tweak it further! Check this page for detailed documentation.

    Questions? Check out the FAQ below!

    FAQ

    Click here to expand the FAQ section

    How often will the code scanning analysis run?

    By default, code scanning will trigger a scan with the CodeQL engine on the following events:

    • On every pull request — to flag up potential security problems for you to investigate before merging a PR.
    • On every push to your default branch and other protected branches — this keeps the analysis results on your repository’s Security tab up to date.
    • Once a week at a fixed time — to make sure you benefit from the latest updated security analysis even when no code was committed or PRs were opened.

    What will this cost?

    Nothing! The CodeQL engine will run inside GitHub Actions, making use of your unlimited free compute minutes for public repositories.

    What types of problems does CodeQL find?

    The CodeQL engine that powers GitHub code scanning is the exact same engine that powers LGTM.com. The exact set of rules has been tweaked slightly, but you should see almost exactly the same types of alerts as you were used to on LGTM.com: we’ve enabled the security-and-quality query suite for you.

    How do I upgrade my CodeQL engine?

    No need! New versions of the CodeQL analysis are constantly deployed on GitHub.com; your repository will automatically benefit from the most recently released version.

    The analysis doesn’t seem to be working

    If you get an error in GitHub Actions that indicates that CodeQL wasn’t able to analyze your code, please follow the instructions here to debug the analysis.

    How do I disable LGTM.com?

    If you have LGTM’s automatic pull request analysis enabled, then you can follow these steps to disable the LGTM pull request analysis. You don’t actually need to remove your repository from LGTM.com; it will automatically be removed in the next few months as part of the deprecation of LGTM.com (more info here).

    Which source code hosting platforms does code scanning support?

    GitHub code scanning is deeply integrated within GitHub itself. If you’d like to scan source code that is hosted elsewhere, we suggest that you create a mirror of that code on GitHub.

    How do I know this PR is legitimate?

    This PR is filed by the official LGTM.com GitHub App, in line with the deprecation timeline that was announced on the official GitHub Blog. The proposed GitHub Action workflow uses the official open source GitHub CodeQL Action. If you have any other questions or concerns, please join the discussion here in the official GitHub community!

    I have another question / how do I get in touch?

    Please join the discussion here to ask further questions and send us suggestions!

  • feat: add chained input `and.referenceToGroup`

    feat: add chained input `and.referenceToGroup`

    Add a chained input and.referenceToGroup (regex: \k<groupName>) to add a new pattern that references the previously captured groups using the group name.

    The argument of and.referenceToGroup (group name) have type safety by inferring from the Input type and should show autocomplete.

    Not sure if the naming is clear, align with other names and easy to understand? need suggestion!

    Usage

    import { createRegExp, word, oneOrMore } from 'magic-regexp'

const RE = createRegExp(
  word
    .as('firstWord')
    .and(word.as('secondWord'))
    .and(oneOrMore(char))
    .and.referenceToGroup('secondWord')
    .and.referenceToGroup('firstWord')
) // /(?<firstWord>\w)(?<secondWord>\w)(.)+\k<secondWord>\k<firstWord>/

assert.equal(RE.test('TEN<==O==>NET'), true)

    performance testing

    with the amount of inference we're doing, it would be a great enhancement to add some kind of type performance test to ensure that end users' TS checkers or IDEs don't get slower. With metrics, we also will have a basis for making performance improvements.

  • `Predefined Input can not be assigned to InputSource` when using with TypeScript < 4.7

    `Predefined Input can not be assigned to InputSource` when using with TypeScript < 4.7

    I just installed magic-regexp via yarn add magic-regexp and tried the first example from https://regexp.dev/getting-started/examples

    Typescript does not like it though: Argument of type 'Input<"\\d", never>' is not assignable to parameter of type 'InputSource<string, never>'.

    The code can also be simplified even more: const regex = createRegExp(oneOrMore(digit));

    I have created a codesandbox for showcasing this: https://codesandbox.io/s/gracious-swartz-3sdfcs

Since Polisens web queueing solution for getting a passport sucks, and it is more or less impossible to book a time, I wrote this small javascript. What it does is that it automates the searching for a bookable time. In the file you just change the constants to your information and away you go. :)
