### ChatGPT

bundle exec mj chatgpt ask "Who won the World Cup in 1994?" --request-file samples/chatgpt/football-team.yml | jq


Where the config file looks like:

```yaml
request:
  parameters:
    model: gpt-3.5-turbo-16k
    temperature: 0.1
    messages:
    - role: system
      content: You re an expert in futebool history.

Response:

{
  "id": "chatcmpl-90a0HhlOIqYkMPRbuICPy5m798yjQ",
  "object": "chat.completion",
  "created": 1709925425,
  "model": "gpt-3.5-turbo-16k-0613",
  "choices": [
    {
      "index": 0,
      "message": {
        "role": "assistant",
        "content": "The World Cup in 1994 was won by the Brazilian national team. They defeated Italy in the final match, which was held at the Rose Bowl stadium in Pasadena, California, United States. The match ended in a 0-0 draw after extra time, and Brazil won the penalty shootout 3-2 to claim their fourth World Cup title."
      },
      "logprobs": null,
      "finish_reason": "stop"
    }
  ],
  "usage": {
    "prompt_tokens": 31,
    "completion_tokens": 71,
    "total_tokens": 102
  },
  "system_fingerprint": null
}

You can also do jq '.choices[0].message.content':

mj chatgpt ask "Who won the World Cup in 1994?" \
  --config-file samples/chatgpt/football-team.yml | jq '.choices[0].message.content'

# "The World Cup in 1994 was won by the Brazilian national team. They defeated Italy in the final match, which was held at the Rose Bowl stadium in Pasadena, California, United States. The match ended in a 0-0 draw after extra time, and Brazil won the penalty shootout 3-2 to claim their fourth World Cup title."

GraphQl

bundle exec mj graphql query_file AccountUsers.graphql | jq

Your graqphql fiel is a regular file with variables at the top:

# gql-endpoint: http://api.myapi.me/graphql
# gql-header: Authorization: Bearer cb923f33617877578961a19cf4566ec2
# gql-header: Content-Type: application/json
# gql-variables: { "input": { "id": "some-id" } }

query QueryAccountUsers(
  $input: AccountInput!
) {
  account(input: $input) {
    users {
      id
      name
    }
    errors {
      path
      message
    }
  }
}

Alternative file

Examples:

$ mj alternative_file list app/components/attribute_component.rb
app/components/attribute_component.html.erb
app/components/attribute_component.rb
lib/components/attribute_component.rb
spec/components/attribute_component_spec.rb
test/components/attribute_component_test.rb

$ mj alternative_file list app/components/attribute_component.rb  --exists
app/components/attribute_component.html.erb
app/components/attribute_component.rb
spec/components/attribute_component_spec.rb

$ mj alternative_file list app/components/attribute_component.rb  --types=spec
spec/components/attribute_component_spec.rb

$ mj alternative_file next app/components/attribute_component.rb
lib/components/attribute_component.rb

$ mj alternative_file prev app/components/attribute_component.rb
app/components/attribute_component.html.erb

Why? Because you can integrate that command with your IDE/Text Editor. For instance, here's my neovim integration:

vimp.nnoremap('<leader>ak', function()
  open_mj_alternative_file('next', '--exists')
end)

vimp.nnoremap('<leader>aj', function()
  open_mj_alternative_file('prev', '--exists')
end)

function open_mj_alternative_file(subcommand, options)
  file_path = vim.fn.expand('%')
  files = mj_alternative_file(file_path, subcommand, options)
  files = vim.split(files, ' ')
  file = files[1]


  if file ~= '' then
    vim.api.nvim_command('e ' .. file)
  end
end

function mj_alternative_file(file, subcommand, options)
  local cmd = 'mj alternative_file ' .. subcommand .. ' ' .. file .. ' ' .. options
  return execute_command(cmd)
end

function execute_command(cmd)
  print("cmd: " .. cmd)
  local f = io.popen(cmd)
  local s = f:read('*a')
  f:close()
  return s
end

This way I can use <leader>a{direction}, where k is next, and j is previous alternative file.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.
