Improve design of CLI commands structure

[peter-rr]

Reason/Context

We need to improve the design of the CLI to follow the existing common CLI's (Docker, Git, GitHub…) to minimise developer's friction and helping to increase the CLI adoption.

For that reason, it would be a good idea to push this improvement in the "must-have" list of things we need for CLI v1.0

Relates to #37

Description

We would like to follow the Git CLI convention:

1. Verb-noun format: Commands follow a verb-noun format, where the verb describes the action to be performed and the noun is the object of the action. For example, 'git commit' commits changes to the local repository.
2. Single-word commands: Some commands are single words that describe the action to be performed, such as 'git status' to show the status of the current repository.
3. Options: Options follow a single-hyphen or double-hyphen format, with a full word or an abbreviation of the option name. For example, -m or --message is used to specify the commit message.
4. Arguments: Arguments are usually positional, with the first argument being the most important one. For example, 'git clone' requires the repository URL as the first argument.
5. Flags: Flags are single-letter options that modify the behaviour of a command. For example, 'git log -p' shows the patch diff for each commit.
6. Subcommands: Git has several high-level commands, each with its own set of subcommands. For example, 'git remote' is a high-level command that has subcommands like add, remove, and rename.

Proposal

Pattern

asyncapi + namespace + command

Namespace concept

Command will have namespace. A namespace provides a way to organize concepts into distinct, named scopes, which can help avoid naming conflicts and make it easier to manage our CLI at scale.

Examples of namespaces:

• studio
• glee
• config

Examples of commands:

asyncapi studio start
asyncapi studio deploy 
asyncapi generate

Namespaces can be also nested. But we recommend to stick to a minimal level of nested namespaces.

Example of nested namespace:

• config > context

Examples of commands:

asyncapi config context 

Default namespace

If the namespace is omitted then the commands are executed in the default namespace.

The default namespace in that case is the current asyncapi namespace directly including its files.

Examples of commands:

asyncapi new

The command above will create a new asyncapi file.

Can we come up with a list of all the existing commands and make a list of how they would look like?

[peter-rr]

Hmmm...good point! Let me collect them so we can visualize better the potential transformations ✨

[SumantxD]

Looks interesting , I would like to work on it . where can i get a list of all the previous commands @peter-rr @fmvilas Thank You.

[peter-rr]

@SumantxD Here you can find the list with all existing CLI commands so far:

EXISTING COMMANDS

  config    access configs
    context   access context configs
      add
      current
      list
      remove
      use

  diff      find differences between two AsyncAPI files

  optimize  optimize your AsyncAPI specification file

  new       
    file       create a new AsyncAPI file
    glee       create a new Glee project
    project    create a new generic project

  start       start a new local instance of Studio

  validate    validate an AsyncAPI file

  convert     convert Asyncapi documents older to newer versions

  bundle      bundle one or multiple Asyncapi documents and their references together

  generate    generate all kinds of stuff
    fromTemplate    generate whatever you want using templates compatible with AsyncAPI Generator
    models          generate all the typed models for the message payloads defined in the AsyncAPI file
      typescript       generate the models for TypeScript
      csharp           generate the models for C#
      golang           generate the models for Go
      java             generate the models for Java
      javascript       generate the models for JavaScript
      dart             generate the models for Dart
      rust             generate the models for Rust
      kotlin           generate the models for Kotlin

And down below you can see how these commands would look like by following the pattern proposed:

[sambhavgupta0705]

Hey,I would like to know more about this issue and how can I approach it

[peter-rr]

@sambhavgupta0705 @SumantxD First we should agree on the new pattern to be implemented and then decide which commands need to be changed. So feel free to share your ideas, doubts or concerns about it 😄 For instance, after a recent conversation with @Souvikns and @KhudaDad414 we agreed that for some commands like validate, optimize, convert, diff or bundle it makes more sense to execute them in the default namespace asyncapi, not under the namespace file as I proposed above, since those commands actually work with already existing spec files.

Fresh new ideas or different pattern proposals are pretty welcomed ❤️

[Shurtu-gal]

@peter-rr Instead of generate:models

we can have something like generate --models php

[derberg]

At the beginning we had this discussion about verb noun vs noun verb and we finally decided to follow verb + noun and namespace + noun + [verb] and https://clig.dev/.

I still think we should follow https://clig.dev/ and not Git, or any other CLI. Picking Git, or Docker or Kubectl carries a risk that decision is done purely basing on what we are used to use, what we use more often and remember.

Anyway, as stated in readme, we follow verb + noun and you also suggest verb + noun which is confusing. So what is really changing? But then in your proposal you recommend to switch from generate (verb) to generator (noun). It is not specified anywhere that namespace is verb or noun and in your proposal you recommend to change namespace generate to generator, noun followed by nouns only.

I'm not convinced for studio, glee and other new namespaces as there is just one command under. I don't believe that with asyncapi generate fromTemplate or asyncapi new glee we are doing bad things to CLI design. Sometimes you have cases like this, like with kubectl you do kubectl get nodes or kubectl get nodes which is much better than kubectl nodes get or kubectl pods get. In their case get is a great namespace, and also is natural to write. "You want to get pods" or "You want to pod gets"?

Anyway, comparing us with Kubectl is as confusing as comparing us with Git. Thus we need our way following https://clig.dev/ and just inspire form others like we did with asyncapi config as git config and kubectl config was there and seemed common.

Is there some specific command or something you feel is not intuitive and that triggered you to do a proposal?

We need to improve the design of the CLI to follow the existing common CLI's (Docker, Git, GitHub…) to minimise developer's friction and helping to increase the CLI adoption.

cause in my opinion we actually follow common CLIs 😄

I found this nodejs-cli-apps-best-practices hope this helps @derberg @peter-rr @Shurtu-gal @fmvilas

Yeah, I agree with this 👍 It really makes sense in terms of "not reinventing the wheel" and trying to adapt to our needs, not just following what others did.

Is there some specific command or something you feel is not intuitive and that triggered you to do a proposal?

At this moment, I think the only command that may create confusion regarding user experience is asyncapi start since is not clear explicitly what this command is actually going to start. I feel that something like asyncapi studio would be much more intuitive for the purpose of starting a new instance of Studio, then using "studio" namespace as an exception as we are doing already with "config". WDYT? 🤔

[derberg]

the thing is that config is also an action, short for configure

[peter-rr]

Yeah, that's right 😄 Then we could proceed to close the discussion if nobody has any suggestion or a different proposal to share.

yes we can change the name to the studio.i would like to work on this.

• I have worked on multiple issues in CLI https://github.com/asyncapi/cli/pulls?q=is%3Apr+is%3Aclosed+author%3AAayushSaini101 and created a new command from scratch https://github.com/asyncapi/cli/pull/1413.

• Past Completed Bounty Issues:

  1. https://github.com/asyncapi/generator/pull/1061
  2. https://github.com/asyncapi/community/pull/1120

• Bounty Issue submission link for ease of access. Thanks! 👍

[Amzani]

@peter-rr @Shurtu-gal I'm not sure what kind of improvements you suggest here ?

[Shurtu-gal]

@Amzani with the recent haul and the improvement in cli now. I suppose this can be closed.

Ref: https://github.com/asyncapi/cli/issues/551#issuecomment-1613823423

[peter-rr]

Agree 👍 I think the only change we could introduce in the future regarding commands structure depends on the evolution of features from studio and integration of API in CLI as @Amzani mentioned in https://github.com/asyncapi/cli/issues/1090#issuecomment-2145056759
