Initial discussion / direction

The purpose of this repo is to provide a standard which glob libraries can choose to implement if they wish.

## Basic goals

- Define a standard for glob patterns - a specification libraries and languages can refer to for what glob features they support
- Cross-language - this is not a JavaScript-specific standard. globs in all languages should be able to implement the standard
- Define common extensions - extensions to the standard to implement common behaviours seen in glob libraries today
- Produce a standard test suite - if you pass these tests, you comply with the standard (similar to web platform tests)
- Produce a comparison doc of existing libraries - existing docs are misleading or outdated, we should use this opportunity to define an up-to-date one

## Non-goals

- Comply with existing behaviour - most existing libraries disagree. This shouldn't just be a standard inferred from what they have in common
- ??

## Open questions

- [x] How do we want to define the standard? A markdown doc? or using a tool to formally define it somehow
- We will start with [tracey](https://tracey.bearcove.eu/guide/getting-started/#create-your-spec) v2 prerelease and see if we run into any issues.
- [x] Do we care about the API? We could aim to standardise the _behaviour_ and not the API shape
- We should define what options may be available, and suggest naming but not require it.
- This is required if we want to be able to apply the spec to existing implementations, as they will have not only have different naming but also potentially negated.

Esta é uma meta-issue para estabelecer uma especificação de glob entre linguagens. Comece revisando as bibliotecas de trabalhos anteriores listadas e a ferramenta tracey. O objetivo é definir um padrão, não escrever código. O trabalho envolve pesquisa, elaboração da especificação e possivelmente a criação de uma suíte de testes. 'Done' significa um documento de especificação claro e um plano para uma suíte de testes.
