dial.nvim

NOTICE: This plugin is work-in-progress yet. User interface is subject to change without notice.

FOR USERS OF THE PREVIOUS VERSION (v0.2.0)

This plugin was released v0.3.0 on 2022/02/20 and is no longer compatible with the old interface. If you have configured the settings for previous versions, please refer to TROUBLESHOOTING.md and reconfigure them.

Abstract

Extended increment/decrement plugin for Neovim. Written in Lua.

Features

Increment/decrement based on various type of rules
- n-ary (2 <= n <= 36) integers
- date and time
- constants (an ordered set of specific strings, such as a keyword or operator)
  - true ⇄ false
  - && ⇄ ||
  - a ⇄ b ⇄ ... ⇄ z
- hex colors
- semantic version
Support <C-a> / <C-x> / g<C-a> / g<C-x> in VISUAL mode
Flexible configuration of increment/decrement targets
- Rules that are valid only in specific FileType
- Rules that are valid only in VISUAL mode
Support counter
Support dot repeat (without overriding the behavior of .)

Installation

dial.nvim requires Neovim >=0.5.0 (>=0.6.1 is recommended). You can install dial.nvim by following the instructions of your favorite package manager.

Usage

This plugin does not provide or override any default key-mappings. To use this plugin, you need to assign the plugin key-mapping to the key you like, as shown below:

nmap  <C-a>  <Plug>(dial-increment)
nmap  <C-x>  <Plug>(dial-decrement)
nmap g<C-a> g<Plug>(dial-increment)
nmap g<C-x> g<Plug>(dial-decrement)
vmap  <C-a>  <Plug>(dial-increment)
vmap  <C-x>  <Plug>(dial-decrement)
vmap g<C-a> g<Plug>(dial-increment)
vmap g<C-x> g<Plug>(dial-decrement)

Note: When you use "g(dial-increment)" or "g(dial-decrement)" on the right side, remap option must be enabled.

Or you can configure it with Lua as follows:

vim.keymap.set("n", "<C-a>", function()
    require("dial.map").manipulate("increment", "normal")
end)
vim.keymap.set("n", "<C-x>", function()
    require("dial.map").manipulate("decrement", "normal")
end)
vim.keymap.set("n", "g<C-a>", function()
    require("dial.map").manipulate("increment", "gnormal")
end)
vim.keymap.set("n", "g<C-x>", function()
    require("dial.map").manipulate("decrement", "gnormal")
end)
vim.keymap.set("v", "<C-a>", function()
    require("dial.map").manipulate("increment", "visual")
end)
vim.keymap.set("v", "<C-x>", function()
    require("dial.map").manipulate("decrement", "visual")
end)
vim.keymap.set("v", "g<C-a>", function()
    require("dial.map").manipulate("increment", "gvisual")
end)
vim.keymap.set("v", "g<C-x>", function()
    require("dial.map").manipulate("decrement", "gvisual")
end)

Configuration

In this plugin, flexible increment/decrement rules can be set by using augend and group, where augend represents the target of the increment/decrement operation, and group represents a group of multiple augends.

local augend = require("dial.augend")
require("dial.config").augends:register_group{
  -- default augends used when no group name is specified
  default = {
    augend.integer.alias.decimal,   -- nonnegative decimal number (0, 1, 2, 3, ...)
    augend.integer.alias.hex,       -- nonnegative hex number  (0x01, 0x1a1f, etc.)
    augend.date.alias["%Y/%m/%d"],  -- date (2022/02/19, etc.)
  },

  -- augends used when group with name `mygroup` is specified
  mygroup = {
    augend.integer.alias.decimal,
    augend.constant.alias.bool,    -- boolean value (true <-> false)
    augend.date.alias["%m/%d/%Y"], -- date (02/19/2022, etc.)
  }
}

To define a group, use the augends:register_group function in the "dial.config" module. The arguments is a dictionary whose keys are the group names and whose values are the list of augends.
Various augends are defined "dial.augend" by default.

To specify the group of augends, you can use expression register (:h @=) as follows:

"=mygroup<CR><C-a>

If it is tedious to specify the expression register for each operation, you can "map" it:

nmap <Leader>a "=mygroup<CR><Plug>(dial-increment)

Alternatively, you can set the same mapping without expression register:

vim.keymap.set("n", "<Leader>a", require("dial.map").inc_normal("mygroup"), {noremap = true})

When you don't specify any group name in the way described above, the addends in the default group is used instead.

List of Augends

For simplicity, we define the variable augend as follows.

local augend = require("dial.augend")

`integer`

n-based integer (2 <= n <= 36). You can use this rule with augend.integer.new{ ...opts }.

require("dial.config").augends:register_group{
  default = {
    -- uppercase hex number (0x1A1A, 0xEEFE, etc.)
    augend.integer.new{
      radix = 16,
      prefix = "0x",
      natural = true,
      case = "upper",
    },
  },
}

`date`

Date and time.

require("dial.config").augends:register_group{
  default = {
    -- date with format `yyyy/mm/dd`
    augend.date.new{
        pattern = "%Y/%m/%d",
        default_kind = "day",
        -- if true, it does not match dates which does not exist, such as 2022/05/32
        only_valid = true,
        -- if true, it only matches dates with word boundary
        word = false,
    },
  },
}

In the pattern argument, you can use the following escape sequences:

Sequence	Meaning
`%Y`	4-digit year. (e.g. `2022`)
`%y`	Last 2 digits of year. The upper 2 digits are interpreted as `20`. (e.g. `22`)
`%m`	2-digit month. (e.g. `09`)
`%d`	2-digit day. (e.g. `28`)
`%H`	2-digit hour, expressed in 24 hours. (e.g. `15`)
`%I`	2-digit hour, expressed in 12 hours. (e.g. `03`)
`%M`	2-digit minute. (e.g. `05`)
`%S`	2-digit second. (e.g. `08`)
`%-y`	1- or 2-digit year. (e.g. `9` represents 2009)
`%-m`	1- or 2-digit month. (e.g. `9`)
`%-d`	1- or 2-digit day. (e.g. `28`)
`%-H`	1- or 2-digit hour, expressed in 24 hours. (e.g. `15`)
`%-I`	1- or 2-digit hour, expressed in 12 hours. (e.g. `3`)
`%-M`	1- or 2-digit minute. (e.g. `5`)
`%-S`	1- or 2-digit second. (e.g. `8`)
`%a`	English weekdays (`Sun`, `Mon`, ..., `Sat`)
`%A`	English full weekdays (`Sunday`, `Monday`, ..., `Saturday`)
`%b`	English month names (`Jan`, ..., `Dec`)
`%B`	English month full names (`January`, ..., `December`)
`%p`	`AM` or `PM`.
`%J`	Japanese weekdays (`日`, `月`, ..., `土`)

`constant`

Predefined sequence of strings. You can use this rule with augend.constant.new{ ...opts }.

require("dial.config").augends:register_group{
  default = {
    -- uppercase hex number (0x1A1A, 0xEEFE, etc.)
    augend.constant.new{
      elements = {"and", "or"},
      word = true, -- if false, "sand" is incremented into "sor", "doctor" into "doctand", etc.
      cyclic = true,  -- "or" is incremented into "and".
    },
    augend.constant.new{
      elements = {"&&", "||"},
      word = false,
      cyclic = true,
    },
  },
}

`hexcolor`

RGB color code such as #000000 and #ffffff.

require("dial.config").augends:register_group{
  default = {
    -- uppercase hex number (0x1A1A, 0xEEFE, etc.)
    augend.hexcolor.new{
      case = "lower",
    },
  },
}

`semver`

Semantic versions. You can use this rule by augend alias described below.

It differs from a simple nonnegative integer increment/decrement in these ways:

When the cursor is before the semver string, the patch version is incremented.
When the minor version is incremented, the patch version is reset to zero.
When the major version is incremented, the minor and patch versions are reset to zero.

`user`

Custom augends.

require("dial.config").augends:register_group{
  default = {
    -- uppercase hex number (0x1A1A, 0xEEFE, etc.)
    augend.user.new{
      find = require("dial.augend.common").find_pattern("%d+"),
      add = function(text, addend, cursor)
          local n = tonumber(text)
          n = math.floor(n * (2 ^ addend))
          text = tostring(n)
          cursor = #text
          return {text = text, cursor = cursor}
      end
    },
  },
}

Augend Alias

Some augend rules are defined as alias. It can be used directly without using new function.

require("dial.config").augends:register_group{
  default = {
    augend.integer.alias.decimal,
    augend.integer.alias.hex,
    augend.date.alias["%Y/%m/%d"],
  },
}
