< Concept of alignment rule >_________________________________________________~
                                          *easy-align-concept-of-alignment-rule*
                                                                *easy-align-5-1*

Though easy-align can align lines of text around any delimiter, it provides
shortcuts for the most common use cases with the concept of "alignment rule".

An alignment rule is a predefined set of options for common alignment tasks,
which is identified by a single character, DELIMITER KEY, such as <Space>,
`=`, `:`, `.`, `|`, `&`, `#`, and `,`.

Think of it as a shortcut. Instead of writing regular expression and setting
several options, you can just type in a single character.


< Execution models >__________________________________________________________~
                                                   *easy-align-execution-models*
                                                                *easy-align-5-2*

There are two ways to use easy-align.


1. Using <Plug> mappings~
                                              *easy-align-1-using-plug-mappings*
                                                              *easy-align-5-2-1*

The recommended method is to use <Plug> mappings as described earlier.

                                                         *<Plug>(LiveEasyAlign)*

 ----------------------+--------+-----------------------------------------------------
 Mapping               | Mode   | Description                                         ~
 ----------------------+--------+-----------------------------------------------------
 <Plug>(EasyAlign)     | normal | Start interactive mode for a motion/text object
 <Plug>(EasyAlign)     | visual | Start interactive mode for the selection
 <Plug>(LiveEasyAlign) | normal | Start live-interactive mode for a motion/text object
 <Plug>(LiveEasyAlign) | visual | Start live-interactive mode for the selection
 ----------------------+--------+-----------------------------------------------------


2. Using :EasyAlign command~
                                          *easy-align-2-using-easyalign-command*
                                                              *easy-align-5-2-2*

                                                                    *:EasyAlign*

If you prefer command-line or do not want to start interactive mode, you can
use `:EasyAlign` command instead.

                                                                *:LiveEasyAlign*

 -------------------------------------------+-----------------------------------------------
 Mode                                       | Command                                       ~
 -------------------------------------------+-----------------------------------------------
 Interactive mode                           |  `:EasyAlign[!] [OPTIONS]`
 Live interactive mode                      |  `:LiveEasyAlign[!] [...]`
 Non-interactive mode (predefined rules)    |  `:EasyAlign[!] [N-th] DELIMITER_KEY [OPTIONS]`
 Non-interactive mode (regular expressions) |  `:EasyAlign[!] [N-th] /REGEXP/ [OPTIONS]`
 -------------------------------------------+-----------------------------------------------


< Interactive mode >__________________________________________________________~
                                                   *easy-align-interactive-mode*
                                                                *easy-align-5-3*

The following sections will assume that you have <Plug>(EasyAlign) mappings in
your .vimrc as below:
>
    " Start interactive EasyAlign in visual mode (e.g. vip<Enter>)
    vmap <Enter> <Plug>(EasyAlign)

    " Start interactive EasyAlign for a motion/text object (e.g. gaip)
    nmap ga <Plug>(EasyAlign)
<
With these mappings, you can align text with only a few keystrokes.

 1. <Enter> key in visual mode, or `ga` followed by a motion or a text object to
    start interactive mode
 2. Optional: Enter keys to select alignment mode (left, right, or center)
 3. Optional: N-th delimiter (default: 1)
   - `1` Around the 1st occurrences of delimiters
   - `2` Around the 2nd occurrences of delimiters
   - ...
   - `*` Around all occurrences of delimiters
   - `**` Left-right alternating alignment around all delimiters
   - `-` Around the last occurrences of delimiters (`-1`)
   - `-2` Around the second to last occurrences of delimiters
   - ...
 4. Delimiter key (a single keystroke; <Space>, `=`, `:`, `.`, `|`, `&`, `#`, `,`)


Predefined alignment rules~
                                         *easy-align-predefined-alignment-rules*
                                                              *easy-align-5-3-1*

  `:`            | Suitable for formatting JSON or YAML
  `.`            | Multi-line method chaining

 --------------+--------------------------------------------------------------------

                                                       *g:easy_align_delimiters*

You can override these default rules or define your own rules with
`g:easy_align_delimiters`, which will be described in {the later section}{5}.

                                                              *easy-align-5-3-2*

 ------------------+------------------------------------+--------------------


Using regular expressions~
                                          *easy-align-using-regular-expressions*
                                                              *easy-align-5-3-3*

Instead of finishing the command with a predefined delimiter key, you can type
in a regular expression after CTRL-/ or CTRL-X key. For example, if you want
to align text around all occurrences of numbers:

 - <Enter>
 - `*`
 - CTRL-X
   - `[0-9]\+`


Alignment options in interactive mode~
                              *easy-align-alignment-options-in-interactive-mode*
                                                              *easy-align-5-3-4*

While in interactive mode, you can set alignment options using special
shortcut keys listed below. The meaning of each option will be described in
{the following sections}{6}.

 --------+--------------------+---------------------------------------------------
 Key     | Option             | Values                                            ~
 --------+--------------------+---------------------------------------------------
 CTRL-F  |  `filter`            | Input string ( `[gv]/.*/?` )
 CTRL-I  |  `indentation`       | shallow, deep, none, keep
 CTRL-L  |  `left_margin`       | Input number or string
 CTRL-R  |  `right_margin`      | Input number or string
 CTRL-D  |  `delimiter_align`   | left, center, right
 CTRL-U  |  `ignore_unmatched`  | 0, 1
 CTRL-G  |  `ignore_groups`     | [], ["String'], ["Comment'], ["String', "Comment']
 CTRL-A  |  `align`             | Input string ( `/[lrc]+\*{0,2}/` )
 <Left>  |  `stick_to_left`     |  `{ 'stick_to_left': 1, 'left_margin': 0 }`
 <Right> |  `stick_to_left`     |  `{ 'stick_to_left': 0, 'left_margin': 1 }`
 <Down>  |  `*_margin`          |  `{ 'left_margin': 0, 'right_margin': 0 }`

< Live interactive mode >_____________________________________________________~
                                              *easy-align-live-interactive-mode*
                                                                *easy-align-5-4*

If you're performing a complex alignment where multiple options should be
carefully adjusted, try "live interactive mode" where you can preview the
result of the alignment on-the-fly as you type in.

Live interactive mode can be started with either <Plug>(LiveEasyAlign) map or
`:LiveEasyAlign` command. Or you can switch to live interactive mode while in
ordinary interactive mode by pressing CTRL-P. (P for Preview)

In live interactive mode, you have to type in the same delimiter (or CTRL-X on
regular expression) again to finalize the alignment. This allows you to
preview the result of the alignment and freely change the delimiter using
backspace key without leaving the interactive mode.


< Non-interactive mode >______________________________________________________~
                                               *easy-align-non-interactive-mode*
                                                                *easy-align-5-5*

Instead of starting interactive mode, you can use declarative, non-interactive
`:EasyAlign` command.
>
    " Using predefined alignment rules
    "   :EasyAlign[!] [N-th] DELIMITER_KEY [OPTIONS]
    :EasyAlign :
    :EasyAlign =
    :EasyAlign *=
    :EasyAlign 3\

    " Using arbitrary regular expressions
    "   :EasyAlign[!] [N-th] /REGEXP/ [OPTIONS]
    :EasyAlign /[:;]\+/
    :EasyAlign 2/[:;]\+/
    :EasyAlign */[:;]\+/
    :EasyAlign **/[:;]\+/
<
A command can end with alignment options, {each of which will be discussed in
detail later}{6}, in Vim dictionary format.

 - `:EasyAlign * /[:;]\+/ { 'stick_to_left': 1, 'left_margin': 0 }`

`stick_to_left` of 1 means that the matched delimiter should be positioned
right next to the preceding token, and `left_margin` of 0 removes the margin
on the left. So we get:
>
    apple;: banana::   cake
    data;;  exchange:; format
<
Option names are fuzzy-matched, so you can write as follows:

 - `:EasyAlign * /[:;]\+/ { 'stl': 1, 'l': 0 }`

You can even omit spaces between the arguments, so concisely (or cryptically):

 - `:EasyAlign*/[:;]\+/{'s':1,'l':0}`

Nice. But let's make it even shorter. Option values can be written in
shorthand notation.

 - `:EasyAlign*/[:;]\+/<l0`

The following table summarizes the shorthand notation.

 -------------------+-----------
 Option             | Expression~
 -------------------+-----------
  `filter`            |  `[gv]/.*/`
  `left_margin`       |  `l[0-9]+`
  `right_margin`      |  `r[0-9]+`
  `stick_to_left`     |  `<`  or  `>`
  `ignore_unmatched`  |  `iu[01]`
  `ignore_groups`     |  `ig\[.*\]`
  `align`             |  `a[lrc*]*`
  `delimiter_align`   |  `d[lrc]`
  `indentation`       |  `i[ksdn]`
 -------------------+-----------

For your information, the same operation can be done in interactive mode as
follows:

 - <Enter>
 - `*`
 - <Left>
 - CTRL-X
   - `[:;]\+`

< Partial alignment in blockwise-visual mode >________________________________~
                         *easy-align-partial-alignment-in-blockwise-visual-mode*
                                                                *easy-align-5-6*

In blockwise-visual mode (CTRL-V), EasyAlign command aligns only the selected
text in the block, instead of the whole lines in the range.

Consider the following case where you want to align text around `=>`
operators.
>
    my_hash = { :a => 1,
                :aa => 2,
                :aaa => 3 }
<
In non-blockwise visual mode (`v` / `V`), <Enter>= won't work since the
assignment operator in the first line gets in the way. So we instead enter
blockwise-visual mode (CTRL-V), and select the text around`=>` operators, then
press <Enter>=.
>
    my_hash = { :a   => 1,
                :aa  => 2,
                :aaa => 3 }
<
However, in this case, we don't really need blockwise visual mode since the
same can be easily done using the negative N-th parameter: <Enter>-=


                                                                  *easy-align-6*

There are 4 ways to set alignment options (from lowest precedence to highest):

 1. Some option values can be set with corresponding global variables
 2. Option values can be specified in the definition of each alignment rule
 3. Option values can be given as arguments to `:EasyAlign` command
 4. Option values can be set in interactive mode using special shortcut keys

                      *g:easy_align_ignore_groups* *g:easy_align_ignore_unmatched*
                         *g:easy_align_indentation* *g:easy_align_delimiter_align*

< Filtering lines >___________________________________________________________~
                                                    *easy-align-filtering-lines*
                                                                *easy-align-6-2*

With `filter` option, you can align lines that only match or do not match a
given pattern. There are several ways to set the pattern.

 1. Press CTRL-F in interactive mode and type in `g/pat/` or `v/pat/`
 2. In command-line, it can be written in dictionary format: `{'filter':
    'g/pat/'}`
 3. Or in shorthand notation: `g/pat/` or `v/pat/`

(You don't need to escape "/'s in the regular expression)


Examples~

                                                              *easy-align-6-2-1*
>
    " Start interactive mode with filter option set to g/hello/
    EasyAlign g/hello/

    " Start live interactive mode with filter option set to v/goodbye/
    LiveEasyAlign v/goodbye/

    " Align the lines with 'hi' around the first colons
    EasyAlign:g/hi/
<

< Ignoring delimiters in comments or strings >________________________________~
                         *easy-align-ignoring-delimiters-in-comments-or-strings*
                                                                *easy-align-6-3*

EasyAlign can be configured to ignore delimiters in certain syntax highlight
groups, such as code comments or strings. By default, delimiters that are
highlighted as code comments or strings are ignored.
>
    " Default:
    "   If a delimiter is in a highlight group whose name matches
    "   any of the following regular expressions, it will be ignored.
    let g:easy_align_ignore_groups = ['Comment', 'String']
<
For example, the following paragraph
>
    {
      # Quantity of apples: 1
      apple: 1,
      # Quantity of bananas: 2
      bananas: 2,
      # Quantity of grape:fruits: 3
      'grape:fruits': 3
    }
<
becomes as follows on <Enter>: (or `:EasyAlign:`)
>
    {
      # Quantity of apples: 1
      apple:          1,
      # Quantity of bananas: 2
      bananas:        2,
      # Quantity of grape:fruits: 3
      'grape:fruits': 3
    }
<
Naturally, this feature only works when syntax highlighting is enabled.

You can change the default rule by using one of these 4 methods.

 1. Press CTRL-G in interactive mode to switch groups
 2. Define global `g:easy_align_ignore_groups` list
 3. Define a custom rule in `g:easy_align_delimiters` with `ignore_groups` option
 4. Provide `ignore_groups` option to `:EasyAlign` command. e.g. `:EasyAlign:ig[]`

For example if you set `ignore_groups` option to be an empty list, you get
>
    {
      # Quantity of apples:  1
      apple:                 1,
      # Quantity of bananas: 2
      bananas:               2,
      # Quantity of grape:   fruits: 3
      'grape:                fruits': 3
    }
<
If a pattern in `ignore_groups` is prepended by a `!`, it will have the
opposite meaning. For instance, if `ignore_groups` is given as `['!Comment']`,
delimiters that are not highlighted as Comment will be ignored during the
alignment.

To make `ignore_groups` work, and to debug the related issues, it is useful to
know which highlight group a certain location in a file belongs to. A special
function exists for this purpose, returning exactly the name of the highlight
group that is used by the easy align plugin.
>
    " Highlight group name of the cursor position
    echo easy_align#get_highlight_group_name()

    " Highlight group name of the line 10, column 20
    echo easy_align#get_highlight_group_name(10, 20)
<

< Ignoring unmatched lines >__________________________________________________~
                                           *easy-align-ignoring-unmatched-lines*
                                                                *easy-align-6-4*

`ignore_unmatched` option determines how EasyAlign command processes lines
that do not have N-th delimiter.

 1. In left-alignment mode, they are ignored
 2. In right or center-alignment mode, they are not ignored, and the last tokens
    from those lines are aligned as well as if there is an invisible trailing
    delimiter at the end of each line
 3. If `ignore_unmatched` is 1, they are ignored regardless of the alignment mode
 4. If `ignore_unmatched` is 0, they are not ignored regardless of the mode

Let's take an example. When we align the following code block around the (1st)
colons,
>
    {
      apple: proc {
        this_line_does_not_have_a_colon
      },
      bananas: 2,
      grapefruits: 3
    }
<
this is usually what we want.
>
    {
      apple:       proc {
        this_line_does_not_have_a_colon
      },
      bananas:     2,
      grapefruits: 3
    }
<
However, we can override this default behavior by setting `ignore_unmatched`
option to zero using one of the following methods.

 1. Press CTRL-U in interactive mode to toggle `ignore_unmatched` option
 2. Set the global `g:easy_align_ignore_unmatched` variable to 0
 3. Define a custom alignment rule with `ignore_unmatched` option set to 0
 4. Provide `ignore_unmatched` option to `:EasyAlign` command. e.g.
    `:EasyAlign:iu0`

Then we get,
>
    {
      apple:                             proc {
        this_line_does_not_have_a_colon
      },
      bananas:                           2,
      grapefruits:                       3
    }
<

< Aligning delimiters of different lengths >__________________________________~
                           *easy-align-aligning-delimiters-of-different-lengths*
                                                                *easy-align-6-5*

Global `g:easy_align_delimiter_align` option and rule-wise/command-wise
`delimiter_align` option determines how matched delimiters of different
lengths are aligned.
>
    apple = 1
    banana += apple
    cake ||= banana
<
By default, delimiters are right-aligned as follows.
>
    apple    = 1
    banana  += apple
    cake   ||= banana
<
However, with `:EasyAlign=dl`, delimiters are left-aligned.
>
    apple  =   1
    banana +=  apple
    cake   ||= banana
<
And on `:EasyAlign=dc`, center-aligned.
>
    apple   =  1
    banana +=  apple
    cake   ||= banana
<
In interactive mode, you can change the option value with CTRL-D key.


< Adjusting indentation >_____________________________________________________~
                                              *easy-align-adjusting-indentation*
                                                                *easy-align-6-6*

By default :EasyAlign command keeps the original indentation of the lines. But
then again we have `indentation` option. See the following example.
>
    # Lines with different indentation
      apple = 1
        banana = 2
          cake = 3
            daisy = 4
         eggplant = 5

    # Default: _k_eep the original indentation
    #   :EasyAlign=
      apple       = 1
        banana    = 2
          cake    = 3
            daisy = 4
         eggplant = 5

    # Use the _s_hallowest indentation among the lines
    #   :EasyAlign=is
      apple    = 1
      banana   = 2
      cake     = 3
      daisy    = 4
      eggplant = 5

    # Use the _d_eepest indentation among the lines
    #   :EasyAlign=id
            apple    = 1
            banana   = 2
            cake     = 3
            daisy    = 4
            eggplant = 5

    # Indentation: _n_one
    #   :EasyAlign=in
    apple    = 1
    banana   = 2
    cake     = 3
    daisy    = 4
    eggplant = 5
<
In interactive mode, you can change the option value with CTRL-I key.


< Alignments over multiple occurrences of delimiters >________________________~
                 *easy-align-alignments-over-multiple-occurrences-of-delimiters*
                                                                *easy-align-6-7*

As stated above, "N-th" parameter is used to target specific occurrences of
the delimiter when it appears multiple times in each line.

To recap:
>
    " Left-alignment around the FIRST occurrences of delimiters
    :EasyAlign =

    " Left-alignment around the SECOND occurrences of delimiters
    :EasyAlign 2=

    " Left-alignment around the LAST occurrences of delimiters
    :EasyAlign -=

    " Left-alignment around ALL occurrences of delimiters
    :EasyAlign *=

    " Left-right ALTERNATING alignment around all occurrences of delimiters
    :EasyAlign **=

    " Right-left ALTERNATING alignment around all occurrences of delimiters
    :EasyAlign! **=
<
In addition to these, you can fine-tune alignments over multiple occurrences
of the delimiters with "align' option. (The option can also be set in
interactive mode with the special key CTRL-A)
>
    " Left alignment over the first two occurrences of delimiters
    :EasyAlign = { 'align': 'll' }

    " Right, left, center alignment over the 1st to 3rd occurrences of delimiters
    :EasyAlign = { 'a': 'rlc' }

    " Using shorthand notation
    :EasyAlign = arlc

    " Right, left, center alignment over the 2nd to 4th occurrences of delimiters
    :EasyAlign 2=arlc

    " (*) Repeating alignments (default: l, r, or c)
    "   Right, left, center, center, center, center, ...
    :EasyAlign *=arlc

    " (**) Alternating alignments (default: lr or rl)
    "   Right, left, center, right, left, center, ...
    :EasyAlign **=arlc

    " Right, left, center, center, center, ... repeating alignment
    " over the 3rd to the last occurrences of delimiters
    :EasyAlign 3=arlc*

    " Right, left, center, right, left, center, ... alternating alignment
    " over the 3rd to the last occurrences of delimiters
    :EasyAlign 3=arlc**

Although the default rules should cover the most of the use cases, you can
extend the rules by setting a dictionary named `g:easy_align_delimiters`.

You may refer to the definitions of the default alignment rules {here}{7}.

{It is reported}{8} that 'foldmethod' value of `expr` or `syntax` can
significantly slow down the alignment when editing a large, complex file with
many folds. To alleviate this issue, EasyAlign provides an option to
temporarily set 'foldmethod' to `manual` during the alignment task. In order
to enable this feature, set `g:easy_align_bypass_fold` switch to 1.

In interactive mode, you can choose the alignment mode you want by pressing
enter keys. The non-bang command, `:EasyAlign` starts in left-alignment mode
and changes to right and center mode as you press enter keys, while the bang
version first starts in right-alignment mode.

 - `:EasyAlign`
   - Left, Right, Center
 - `:EasyAlign!`
   - Right, Left, Center

If you do not prefer this default mode transition, you can define your own
