JSON output for nextflow info

[ewels]

It would be great if nextflow list command showed some additional information about each pipeline that is in the nextflow cache.

Most useful info would be (in order of preference):

• Name
• Commit hash
• Full remote name
• Active git branch
• Date of the last pull if possible? (eg. as here).
• Path to cloned pipeline? (maybe not desirable to advertise this?)

I guess that if you go the full distance and print all of this it will be a bit much to show. Perhaps it could have a verbose mode? Or cli arguments for which fields to show?

Apologies, I should really RTFM before creating issues!

nextflow info does basically everything I want 👍

Ok - I will modify this request a little then.. Please could we have an option for JSON output? 😁

[ewels]

Also, having all of this information with a single call to nextflow list would also be very nice :)

But these are both very minor requests really, so feel free to ignore and close if you would rather!

I think it makes more sense to extend the list command adding a -o flag (output) to support both json and yaml format with the extra information you are proposing.

Added -o json|ymal option, eg:

$ nextflow info hello -o yaml
projectName: nextflow-io/hello
repository: https://github.com/nextflow-io/hello
localPath: https://github.com/nextflow-io/hello
manifest: {mainScript: main.nf, nextflowVersion: null, author: null, defaultBranch: master,
  description: null, gitmodules: null, homePage: null, version: null}
revisions:
  current: master
  master: master
  branches:
  - {name: master, commitId: c9b0ec72860c378a214402225fcec2e8bbf23878}
  - {name: mybranch, commitId: 1c3e9e7404127514d69369cd87f8036830f5cf64}
  - {name: testing, commitId: c36085ebd8a031464c7580910e714bf122903cc1}
  tags:
  - {name: v1.1, commitId: baba3959d7527e0205738ebeb81373858c775a39}
  - {name: v1.2, commitId: 0ec2ecd0ac13bc7e32594c0258ebce55e383d241}

$ nextflow info nextflow-io/hello -o json 
{
    "projectName": "nextflow-io/hello",
    "repository": "https://github.com/nextflow-io/hello",
    "localPath": "https://github.com/nextflow-io/hello",
    "manifest": {
        "mainScript": "main.nf",
        "nextflowVersion": null,
        "author": null,
        "defaultBranch": "master",
        "description": null,
        "gitmodules": null,
        "homePage": null,
        "version": null
    },
    "revisions": {
        "current": "master",
        "master": "master",
        "branches": [
            {
                "name": "master",
                "commitId": "c9b0ec72860c378a214402225fcec2e8bbf23878"
            },
            {
                "name": "mybranch",
                "commitId": "1c3e9e7404127514d69369cd87f8036830f5cf64"
            },
            {
                "name": "testing",
                "commitId": "c36085ebd8a031464c7580910e714bf122903cc1"
            }
        ],
        "tags": [
            {
                "name": "v1.1",
                "commitId": "baba3959d7527e0205738ebeb81373858c775a39"
            },
            {
                "name": "v1.2",
                "commitId": "0ec2ecd0ac13bc7e32594c0258ebce55e383d241"
            }
        ]
    }
}

Moreover I demoted the check for remote changes as optional with the -u option because it takes too long.

$  nextflow info hello -o yaml -u
projectName: nextflow-io/hello
repository: https://github.com/nextflow-io/hello
localPath: https://github.com/nextflow-io/hello
manifest: {mainScript: main.nf, nextflowVersion: null, author: null, defaultBranch: master,
  description: null, gitmodules: null, homePage: null, version: null}
revisions:
  current: master
  master: master
  branches:
  - {name: master, latestId: a9012339ce857d6ec7a078281813d8a93645a3e7, commitId: c9b0ec72860c378a214402225fcec2e8bbf23878}
  - {name: mybranch, commitId: 1c3e9e7404127514d69369cd87f8036830f5cf64}
