unzipObjWith

See original GitHub issue

To form a partial isomorphism with R.zipObj the transformation needs to look like this:

const patient = {
  'abbrev@1':{
    version:'1.0.9',
    resolved:'https://registry.yarnpkg.com/abbrev/-/abbrev-1.0.9.tgz#91b4792588a7738c25f35dd6f63752a2f8776135'
  },
  'shell-quote@git+https://github.com/srghma/node-shell-quote.git#without_unlicenced_jsonify':{
    version:'1.6.0',
    resolved:'git+https://github.com/srghma/node-shell-quote.git#0aa381896e0cd7409ead15fd444f225807a61e0a'
  },
  '@graphile/plugin-supporter@git+https://1234user:1234pass@git.graphile.com/git/users/1234user/postgraphile-supporter.git':{
    version:'1.6.0',
    resolved:'git+https://1234user:1234pass@git.graphile.com/git/users/1234user/postgraphile-supporter.git#1234commit'
  },
}

const result = unzipObjWith((value, key) => [key, { ...value, name: key }]), patient)

const expected = [
  [
    'abbrev@1', 
    'shell-quote@git+https://github.com/srghma/node-shell-quote.git#without_unlicenced_jsonify',
    '@graphile/plugin-supporter@git+https://1234user:1234pass@git.graphile.com/git/users/1234user/postgraphile-supporter.git',
 ],
 [
  {
    name: 'abbrev@1',
    version:'1.0.9',
    resolved:'https://registry.yarnpkg.com/abbrev/-/abbrev-1.0.9.tgz#91b4792588a7738c25f35dd6f63752a2f8776135'
  },
  {
    name: 'shell-quote@git+https://github.com/srghma/node-shell-quote.git#without_unlicenced_jsonify',
    version:'1.6.0',
    resolved:'git+https://github.com/srghma/node-shell-quote.git#0aa381896e0cd7409ead15fd444f225807a61e0a'
  },
  {
    name:   '@graphile/plugin-supporter@git+https://1234user:1234pass@git.graphile.com/git/users/1234user/postgraphile-supporter.git',
    version:'1.6.0',
    resolved:'git+https://1234user:1234pass@git.graphile.com/git/users/1234user/postgraphile-supporter.git#1234commit'
  },
 ]
]

expect(result).toEqual(result)

So you’ll need to do expected[1] to get what you need. I like that this is generic concept which plays with the rest of the zipping algos.

@thomasmichaelwallace cool your understanding is correct.

n.b. I’ll implement it as you’ve shown, but the function’s signiture (value, key) seems counter-intuitive to me given that the array and map are ordered (key, value)?

It’s a convention ramda uses for object transformers. Take a look at https://ramdajs.com/docs/#forEachObjIndexed or https://ramdajs.com/docs/#mapObjIndexed

Interesting- it does make sense to match that consistency. Thanks for pointing it out.
