telescope-alternate

Alternate between common files using pre-defined regexp. Just map the patterns and starting navigating between files that are related.

Telescope alternate also can create files when it is missing (including files with regexp at destination)

Installation

Packer

use { "otavioschwanck/telescope-alternate" }

Setup Example

require('telescope-alternate').setup({
    mappings = {
      { 'app/services/(.*)_services/(.*).rb', { -- alternate from services to contracts / models
        { 'app/contracts/[1]_contracts/[2].rb', 'Contract' }, -- Adding label to switch
        { 'app/models/**/*[1].rb', 'Model', true }, -- Ignore create entry (with true)
      } },
      { 'app/contracts/(.*)_contracts/(.*).rb', { { 'app/services/[1]_services/[2].rb', 'Service' } } }, -- from contracts to services
      -- Search anything on helper folder that contains pluralize version of model.
      --Example: app/models/user.rb -> app/helpers/foo/bar/my_users_helper.rb
      { 'app/models/(.*).rb', { { 'db/helpers/**/*[1:pluralize]*.rb', 'Helper' } } },
      { 'app/**/*.rb', { { 'spec/[1].rb', 'Test' } } }, -- Alternate between file and test
    },
    presets = { 'rails', 'rspec', 'nestjs', 'angular' }, -- Telescope pre-defined mapping presets
    open_only_one_with = 'current_pane', -- when just have only possible file, open it with.  Can also be horizontal_split and vertical_split
    transformers = { -- custom transformers
      change_to_uppercase = function(w) return my_uppercase_method(w) end
    },
    -- telescope_mappings = { -- Change the telescope mappings
    --   i = {
    --     open_current = '<CR>',
    --     open_horizontal = '<C-s>',
    --     open_vertical = '<C-v>',
    --     open_tab = '<C-t>',
    --   },
    --   n = {
    --     open_current = '<CR>',
    --     open_horizontal = '<C-s>',
    --     open_vertical = '<C-v>',
    --     open_tab = '<C-t>',
    --   }
    -- }
  })

-- On your telescope:
require('telescope').load_extension('telescope-alternate')


-- You alternatively can call the setup inside telescope:
require('telescope').setup{
  extensions = {
    ["telescope-alternate"] = {
      mappings = {
        ...your mappings
      },
      presets = { 'rails', 'nestjs' }
    },
  },
}

-- You also can use the verbose way to mapping:
mappings = {
  { pattern = 'app/services/(.*)_services/(.*).rb', targets = {
      { template =  'app/contracts/[1]_contracts/[2].rb', label = 'Contract', enable_new = true } -- enable_new can be a function too.
    }
  },
  { pattern = 'app/contracts/(.*)_contracts/(.*).rb', targets = {
      { template =  'app/services/[1]_services/[2].rb', label = 'Service', enable_new = true }
    }
  },
}

Running telescope alternate

To run alternate, just type:

:Telescope telescope-alternate alternate_file

How to use?

Inside mappings, the syntax is:

{ 'current-file', { { 'destination', 'label', ignoreCreate (true or false) } } }

Each current-file can have multiple destinations.

On current-file, each (.*) is a match.

On destination, each [1], [2], [3] is the text matched text of current-file (by order)

You can run some transformers on the destination, using :function-name, example: [1:singularize] or [1:singularize,camel_to_kebap]

The available functions are:

Function Name	Description
camel_to_kebap	userName -> user-name
kebap_to_camel	user-name -> userName
pluralize	userName -> userNames
singularize	userNames -> userName

Example:

{ 'app/models/(.*).rb', {
  { 'db/helpers/**/*[1]*.rb', 'Helper' } },
  { 'app/controllers/**/*[1:pluralize]_controller.rb', 'Controller' } },
},
