*mini.surround*

*MiniSurround*

Fast and feature-rich surrounding. This is mostly a reimplementation of the

core features of 'machakann/vim-sandwich' with more on top (find

surrounding, highlight surrounding, flexible customization). Can be

configured to have experience similar to 'tpope/vim-surround'.

Features:

- Actions (all of them are dot-repeatable out of the box and respect

|v:count| for searching surrounding) with configurable keymappings:

- Add surrounding with `sa` (in visual mode or on motion).

- Delete surrounding with `sd`.

- Replace surrounding with `sr`.

- Find surrounding with `sf` or `sF` (move cursor right or left).

- Highlight surrounding with `sh`.

- Change number of neighbor lines with `sn` (see |MiniSurround-algorithm|).

- Surrounding is identified by a single character as both "input" (in

`delete` and `replace` start, `find`, and `highlight`) and "output" (in

`add` and `replace` end):

- 'f' - function call (string of alphanumeric symbols or '_' or '.'

followed by balanced '()'). In "input" finds function call, in

"output" prompts user to enter function name.

- 't' - tag. In "input" finds tag with same identifier, in "output"

prompts user to enter tag name.

- All symbols in brackets '()', '[]', '{}', '<>". In "input' represents

balanced brackets (open - with whitespace pad, close - without), in

"output" - left and right parts of brackets.

- '?' - interactive. Prompts user to enter left and right parts.

- All other alphanumeric, punctuation, or space characters represent

surrounding with identical left and right parts.

- Configurable search methods to find not only covering but possibly next,

previous, or nearest surrounding. See more in |MiniSurround.config|.

- All actions involving finding surrounding (delete, replace, find,

highlight) can be used with suffix that changes search method to find

previous/last. See more in |MiniSurround.config|.

Known issues which won't be resolved:

- Search for surrounding is done using Lua patterns (regex-like approach).

So certain amount of false positives should be 8000 expected.

- When searching for "input" surrounding, there is no distinction if it is

inside string or comment. So in this case there will be not proper match

for a function call: 'f(a = ")", b = 1)'.

- Tags are searched using regex-like methods, so issues are inevitable.

Overall it is pretty good, but certain cases won't work. Like self-nested

tags won't match correctly on both ends: '<a><a></a></a>'.

# Setup~

This module needs a setup with `require('mini.surround').setup({})`

(replace `{}` with your `config` table). It will create global Lua table

`MiniSurround` which you can use for scripting or manually (with

`:lua MiniSurround.*`).

See |MiniSurround.config| for `config` structure and default values. It

also has example setup providing experience similar to 'tpope/vim-surround'.

You can override runtime config settings locally to buffer inside

`vim.b.minisurround_config` which should have same structure as

`MiniSurround.config`. See |mini.nvim-buffer-local-config| for more details.

# Example usage~

Regular mappings:

- `saiw)` - add (`sa`) for inner word (`iw`) parenthesis (`)`).

- `saiw?[[<CR>]]<CR>` - add (`sa`) for inner word (`iw`) interactive

surrounding (`?`): `[[` for left and `]]` for right.

- `2sdf` - delete (`sd`) second (`2`) surrounding function call (`f`).

- `sr)tdiv<CR>` - replace (`sr`) surrounding parenthesis (`)`) with tag

(`t`) with identifier 'div' (`div<CR>` in command line prompt).

- `sff` - find right (`sf`) part of surrounding function call (`f`).

- `sh}` - highlight (`sh`) for a brief period of time surrounding curly

brackets (`}`).

Extended mappings (temporary force "prev"/"next" search methods):

- `sdnf` - delete (`sd`) next (`n`) function call (`f`).

- `srlf(` - replace (`sd`) last (`l`) function call (`f`) with padded

bracket (`(`).

- `2sfnt` - find (`sf`) second (2) next (`n`) tag (`t`).

- `shl}` - highlight (`sh`) last (`l`) second (`2`) curly bracket (`}`).

# Comparisons~

- 'tpope/vim-surround':

- 'vim-surround' has completely different, with other focus set of

default mappings, while 'mini.surround' has a more coherent set.

- 'mini.surround' supports dot-repeat, customized search path (see

|MiniSurround.config|), customized specifications (see

|MiniSurround-surround-specification|) allowing usage of tree-sitter

queries (see |MiniSurround.gen_spec.input.treesitter()|),

highlighting and finding surrounding, "last"/"next" extended

mappings. While 'vim-surround' does not.

- 'machakann/vim-sandwich':

- Both have same keybindings for common actions (add, delete, replace).

- Otherwise same differences as with 'tpop/vim-surround' (except

dot-repeat because 'vim-sandwich' supports it).

- 'kylechui/nvim-surround':

- 'nvim-surround' is designed after 'tpope/vim-surround' with same

default mappings and logic, while 'mini.surround' has mappings

similar to 'machakann/vim-sandwich'.

- 'mini.surround' has more flexible customization of input surrounding

(with composed patterns, region pair(s), search methods).

- 'mini.surround' supports |v:count| in input surrounding while

'nvim-surround' doesn't.

- 'mini.surround' supports "last"/"next" extended mappings.

- |mini.ai|:

- Both use similar logic for finding target: textobject in 'mini.ai'

and surrounding pair in 'mini.surround'. While 'mini.ai' uses

extraction pattern for separate `a` and `i` textobjects,

'mini.surround' uses it to select left and right surroundings

(basically a difference between `a` and `i` textobjects).

- Some builtin specifications are slightly different:

- Quotes in 'mini.ai' are balanced, in 'mini.surround' they are not.

- The 'mini.surround' doesn't have argument surrounding.

- Default behavior in 'mini.ai' selects one of the edges into `a`

textobject, while 'mini.surround' - both.

# Highlight groups~

* `MiniSurround` - highlighting of requested surrounding.

To change any highlight group, modify it directly with |:highlight|.

# Disabling~

To disable, set `vim.g.minisurround_disable` (globally) or

`vim.b.minisurround_disable` (for a buffer) to `true`. Considering high

number of different scenarios and customization intentions, writing exact

rules for disabling module's functionality is left to user. See

|mini.nvim-disabling-recipes| for common recipes.

# Silencing ~

To stop module from giving non-error feedback, set `vim.g.minisurround_silence`

(globally) or `vim.b.minisurround_silence` (for a buffer) to `true`.

------------------------------------------------------------------------------

*MiniSurround-surround-builtin*

Builtin surroundings~

This table describes all builtin surroundings along with what they

represent. Explanation:

- `Key` represents the surrounding identifier: single character which should

be typed after action mappings (see |MiniSurround.config.mappings|).

- `Name` is a description of surrounding.

- `Example line` contains a string for which examples are constructed. The

`*` denotes the cursor position over `a` character.

- `Delete` shows the result of typing `sd` followed by surrounding identifier.

It aims to demonstrate "input" surrounding which is also used in replace

with `sr` (surrounding id is typed first), highlight with `sh`, find with

`sf` and `sF`.

- `Replace` shows the result of typing `sr!` followed by surrounding

identifier (with possible follow up from user). It aims to demonstrate

"output" surrounding which is also used in adding with `sa` (followed by

textobject/motion or in Visual mode).

Example: typing `sd)` with cursor on `*` (covers `a` character) changes line

`!( *a (bb) )!` into `! aa (bb) !`. Typing `sr!)` changes same initial line

into `(( aa (bb) ))`.

|---|---------------|---------------|-------------|-----------------|

| { | Balanced {} | !{ *a {bb} }! | !aa {bb}! | { { aa {bb} } } |

|---|---------------|---------------|-------------|-----------------|

| } | Balanced {} | !{ *a {bb} }! | ! aa {bb} ! | {{ aa {bb} }} |

| b | Alias for | !( *a {bb} )! | ! aa {bb} ! | (( aa {bb} )) |

| | ), ], or } | | | |

|---|---------------|---------------|-------------|-----------------|

| | ", ', or ` | | | |

|---|---------------|---------------|-------------|-----------------|

| ? | User prompt | !e * o! | ! a ! | ee a oo |

|---|---------------|---------------|-------------|-----------------|

| t | Tag | !<x>*</x>! | !a! | <y><x>a</x></y> |

|---|---------------|---------------|-------------|-----------------|

|---|---------------|---------------|-------------|-----------------|

| | Default | !_a*a_! | !aaa! | __aaa__ |

|---|---------------|---------------|-------------|-----------------|

Notes:

- All examples assume default `config.search_method`.

- Open brackets differ from close brackets by how they treat inner edge

whitespace: open includes it left and right parts, close does not.

- Output value of `b` alias is same as `)`. For `q` alias - same as `"`.

- Default surrounding is activated for all characters which are not

configured surrounding identifiers. Note: due to special handling of

underlying `x.-x` Lua pattern (see |MiniSurround-search-algorithm|), it

doesn't really support non-trivial `v:count` for "cover" search method.

------------------------------------------------------------------------------

*MiniSurround-glossary*

Note: this is similar to |MiniAi-glossary|.

- REGION - table representing region in a buffer. Fields: <from> and

<to> for inclusive start and end positions (<to> might be `nil` to

describe empty region). Each position is also a table with line <line>

and column <col> (both start at 1). Examples:

- `{ from = { line = 1, col = 1 }, to = { line = 2, col = 1 } }`

- `{ from = { line = 10, col = 10 } }` - empty region.

- REGION PAIR - table representing regions for left and right surroundings.

Fields: <left> and <right> with regions. Examples:

`{`

`left = { from = { line = 1, col = 1 }, to = { line = 1, col = 1 } },`

`right = { from = { line = 1, col = 3 } },`

`}`

- PATTERN - string describing Lua pattern.

- SPAN - interval inside a string (end-exclusive). Like [1, 5). Equal

`from` and `to` edges describe empty span at that point.

- SPAN `A = [a1, a2)` COVERS `B = [b1, b2)` if every element of

`B` is within `A` (`a1 <= b < a2`).

It also is described as B IS NESTED INSIDE A.

- NESTED PATTERN - array of patterns aimed to describe nested spans.

- SPAN MATCHES NESTED PATTERN if there is a sequence of consecutively

nested spans each matching corresponding pattern within substring of

previous span (or input string for first span). Example:

Nested patterns: `{ '%b()', '^. .* .$' }` (balanced `()` with inner space)

Input string: `( ( () ( ) ) )`

`123456789012345`

Here are all matching spans [1, 15) and [3, 13). Both [5, 7) and [8, 10)

match first pattern but not second. All other combinations of `(` and `)`

don't match first pattern (not balanced).

- COMPOSED PATTERN: array with each element describing possible pattern

(or array of them) at that place. Composed pattern basically defines all

possible combinations of nested pattern (their cartesian product).

Examples:

1. Composed pattern: `{ { '%b()', '%b[]' }, '^. .* .$' }`

Composed pattern expanded into equivalent array of nested patterns:

`{ '%b()', '^. .* .$' }` and `{ '%b[]', '^. .* .$' }`

Description: either balanced `()` or balanced `[]` but both with

inner edge space.

2. Composed pattern:

`{ { { '%b()', '^. .* .$' }, { '%b[]', '^.[^ ].*[^ ].$' } }, '.....' }`

Composed pattern expanded into equivalent array of nested patterns:

`{ '%b()', '^. .* .$', '.....' }` and

`{ '%b[]', '^.[^ ].*[^ ].$', '.....' }`

Description: either "balanced `()` with inner edge space" or

"balanced `[]` with no inner edge space", both with 5 or more characters.

- SPAN MATCHES COMPOSED PATTERN if it matches at least one nested pattern

from expanded composed pattern.

------------------------------------------------------------------------------

*MiniSurround-surround-specification*

Surround specification is a table with keys:

- <input> - defines how to find and extract surrounding for "input"

operations (like `delete`). See more in 'Input surrounding' setction.

- <output> - defines what to add on left and right for "output" operations

(like `add`). See more in 'Output surrounding' section.

Example of surround info for builtin `)` identifier: >

{

input = { '%b()', '^.().*().$' },

output = { left = '(', right = ')' }

}

# Input surrounding ~

Specification for input surrounding has a structure of composed pattern

(see |MiniSurround-glossary|) with two differences:

- Last pattern(s) should have two or four empty capture groups denoting

how the last string should be processed to extract surrounding parts:

- Two captures represent left part from start of string to first

capture and right part - from second capture to end of string.

Example: `a()b()c` defines left surrounding as 'a', right - 'c'.

- Four captures define left part inside captures 1 and 2, right part -

inside captures 3 and 4. Example: `a()()b()c()` defines left part as

empty, right part as 'c'.

- Allows callable objects (see |vim.is_callable()|) in certain places

(enables more complex surroundings in exchange of increase in configuration

complexity and computations):

- If specification itself is a callable, it will be called without

arguments and should return one of:

- Composed pattern. Useful for implementing user input. Example of

simplified variant of input surrounding for function call with

name taken from user prompt:

function()

local left_edge = vim.pesc(vim.fn.input('Function name: '))

return { string.format('%s+%%b()', left_edge), '^.-%(().*()%)$' }

end

- Single region pair (see |MiniSurround-glossary|). Useful to allow

full control over surrounding. Will be taken as is. Example of

returning first and last lines of a buffer:

function()

local n_lines = vim.fn.line('$')

return {

left = {

from = { line = 1, col = 1 },

to = { line = 1, col = vim.fn.getline(1):len() },

right = {

from = { line = n_lines, col = 1 },

to = { line = n_lines, col = vim.fn.getline(n_lines):len() },

}

end

- Array of region pairs. Useful for incorporating other instruments,

like treesitter (see |MiniSurround.gen_spec.treesitter()|). The

best region pair will be picked in the same manner as with composed

pattern (respecting options `n_lines`, `search_method`, etc.) using

output region (from start of left region to end of right region).

Example using edges of "best" line with display width more than 80:

function()

local make_line_region_pair = function(n)

local left = { line = n, col = 1 }

local right = { line = n, col = vim.fn.getline(n):len() }

return {

left = { from = left, to = left },

right = { from = right, to = right },

}

end

local res = {}

for i = 1, vim.fn.line('$') do

if vim.fn.getline(i):len() > 80 then

table.insert(res, make_line_region_pair(i))

end

return res

end

- If there is a callable instead of assumed string pattern, it is expected

to have signature `(line, init)` and behave like `pattern:find()`.

It should return two numbers representing span in `line` next after

or at `init` (`nil` if there is no such span).

!IMPORTANT NOTE!: it means that output's `from` shouldn't be strictly

to the left of `init` (it will lead to infinite loop). Not allowed as

last item (as it should be pattern with captures).

Example of matching only balanced parenthesis with big enough width:

{

'%b()',

function(s, init)

if init > 1 or s:len() < 5 then return end

return 1, s:len()

end,

'^.().*().$'

}

More examples:

- See |MiniSurround.gen_spec| for function wrappers to create commonly used

surrounding specifications.

- Pair of balanced brackets from set (used for builtin `b` identifier):

`{ { '%b()', '%b[]', '%b{}' }, '^.().*().$' }`

- Lua block string: `{ '%[%[().-()%]%]' }`

# Output surrounding ~

A table with <left> (plain text string) and <right> (plain text string)

fields. Strings can contain new lines charater `\n` to add multiline parts.

Examples:

- Lua block string: `{ left = '[[', right = ']]' }`

- Brackets on separate lines (indentation is not preserved):

`{ left = '(\n', right = '\n)' }`

------------------------------------------------------------------------------

*MiniSurround-search-algorithm*

Search algorithm design

Search for the input surrounding relies on these principles:

- Input surrounding specification is constructed based on surrounding

identifier (see |MiniSurround-surround-specification|).

- General search is done by converting some 2d buffer region (neighborhood

of reference region) into 1d string (each line is appended with `\n`).

Then search for a best span matching specification is done inside string

(see |MiniSurround-glossary|). After that, span is converted back into 2d

region. Note: first search is done inside reference region lines, and

only after that - inside its neighborhood within `config.n_lines` (see

|MiniSurround.config|).

- The best matching span is chosen by iterating over all spans matching

surrounding specification and comparing them with "current best".

Comparison also depends on reference region (tighter covering is better,

otherwise closer is better) and search method (if span is even considered).

- Extract pair of spans (for left and right regions in region pair) based

on extraction pattern (last item in nested pattern).

- For |v:count| greater than 1, steps are repeated with current best match

becoming reference region. One such additional step is also done if final

region is equal to reference region. Note: |v:count| is not supported for

output surroundings because it brings a lot of inconvenience (for adding

it affects textobject/motion, for replacing it will be used for both

input and output).

Notes:

- Iteration over all matched spans is done in depth-first fashion with

respect to nested pattern.

- It is guaranteed that span is compared only once.

- For the sake of increasing functionality, during iteration over all

matching spans, some Lua patterns in composed pattern are handled

specially.

- `%bxx` (`xx` is two identical characters). It denotes balanced pair

of identical characters and results into "paired" matches. For

example, `%b""` for `"aa" "bb"` would match `"aa"` and `"bb"`, but

not middle `" "`.

- `x.-y` (`x` and `y` are different strings). It results only in matches with

smallest width. For example, `e.-o` for `e e o o` will result only in

middle `e o`. Note: it has some implications for when parts have

quantifiers (like `+`, etc.), which usually can be resolved with

frontier pattern `%f[]`.

# Setup similar to 'tpope/vim-surround'~

This module is primarily designed after 'machakann/vim-sandwich'. To get

behavior closest to 'tpope/vim-surround' (but not identical), use this setup:

require('mini.surround').setup({

mappings = {

add = 'ys',

delete = 'ds',

find = '',

find_left = '',

highlight = '',

replace = 'cs',

update_n_lines = '',

-- Add this only if you don't want to use extended mappings

suffix_last = '',

suffix_next = '',

search_method = 'cover_or_next',

})

-- Remap adding surrounding to Visual mode selection

vim.keymap.del('x', 'ys')

vim.keymap.set('x', 'S', [[:<C-u>lua MiniSurround.add('visual')<CR>]], { silent = true })

-- Make special mapping for "add surrounding for line"

vim.keymap.set('n', 'yss', 'ys_', { remap = true })

# Options~

## Custom surroundings~

User can define own surroundings by supplying `config.custom_surroundings`.

It should be a **table** with keys being single character surrounding

identifier and values - surround specification (see

|MiniSurround-surround-specification|).

General recommendations:

- In `config.custom_surroundings` only some data can be defined (like only

`output`). Other fields will be taken from builtin surroundings.

- Function returning surround info at <input> or <output> fields of

specification is helpful when user input is needed (like asking for

function name). Use |input()| or |MiniSurround.user_input()|. Return

`nil` to stop any current surround operation.

Examples of using `config.custom_surroundings` (see more examples at

|MiniSurround.gen_spec|):

local surround = require('mini.surround')

surround.setup({

custom_surroundings = {

-- Make `)` insert parts with spaces. `input` pattern stays the same.

[')'] = { output = { left = '( ', right = ' )' } },

-- Use function to compute surrounding info

['*'] = {

input = function()

local n_star = MiniSurround.user_input('Number of * to find: ')

local many_star = string.rep('%*', tonumber(n_star) or 1)

return { many_star .. '().-()' .. many_star }

end,

output = function()

local n_star = MiniSurround.user_input('Number of * to output: ')

local many_star = string.rep('*', tonumber(n_star) or 1)

return { left = many_star, right = many_star }

end,

})

-- Create custom surrouding for Lua's block string `[[...]]`. Use this inside

-- autocommand or 'after/ftplugin/lua.lua' file.

vim.b.minisurround_config = {

custom_surroundings = {

s = {

input = { '%[%[().-()%]%]' },

output = { left = '[[', right = ']]' },

}

## Respect selection type ~

Boolean option `config.respect_selection_type` controls whether to respect

selection type when adding and deleting surrounding. When enabled:

- Linewise adding places surroundings on separate lines while indenting

surrounded lines ones.

- Deleting surroundings which look like they were the result of linewise

adding will act to revert it: delete lines with surroundings and dedent

surrounded lines ones.

- Blockwise adding places surroundings on whole edges, not only start and

end of selection. Note: it doesn't really work outside of text and in

presence of multibyte characters; and probably won't due to

implementation difficulties.

## Search method ~

Value of `config.search_method` defines how best match search is done.

Based on its value, one of the following matches will be selected:

- Covering match. Left/right edge is before/after left/right edge of

reference region.

- Previous match. Left/right edge is before left/right edge of reference

region.

- Next match. Left/right edge is after left/right edge of reference region.

- Nearest match. Whichever is closest among previous and next matches.

Possible values are:

- `'cover'` - use only covering match. Don't use either previous or

next; report that there is no surrounding found.

- `'cover_or_next'` (default) - use covering match. If not found, use next.

- `'cover_or_prev'` - use covering match. If not found, use previous.

- `'cover_or_nearest'` - use covering match. If not found, use nearest.

- `'next'` - use next match.

- `'previous'` - use previous match.

- `'nearest'` - use nearest match.

Note: search is first performed on the reference region lines and only

after failure - on the whole neighborhood defined by `config.n_lines`. This

means that with `config.search_method` not equal to `'cover'`, "previous"

or "next" surrounding will end up as search result if they are found on

first stage although covering match might be found in bigger, whole

neighborhood. This design is based on observation that most of the time

operation is done within reference region lines (usually cursor line).

Here is an example of how replacing `)` with `]` surrounding is done based

on a value of `'config.search_method'` when cursor is inside `bbb` word:

- `'cover'`: `(a) bbb (c)` -> `(a) bbb (c)` (with message)

- `'cover_or_next'`: `(a) bbb (c)` -> `(a) bbb [c]`

- `'cover_or_prev'`: `(a) bbb (c)` -> `[a] bbb (c)`

- `'cover_or_nearest'`: depends on cursor position.

For first and second `b` - as in `cover_or_prev` (as previous match is

nearer), for third - as in `cover_or_next` (as next match is nearer).

- `'next'`: `(a) bbb (c)` -> `(a) bbb [c]`. Same outcome for `(bbb)`.

- `'prev'`: `(a) bbb (c)` -> `[a] bbb (c)`. Same outcome for `(bbb)`.

- `'nearest'`: depends on cursor position (same as in `'cover_or_nearest'`).

## Search suffixes~

To provide more searching possibilities, 'mini.surround' creates extended

mappings force "prev" and "next" methods for particular search. It does so

by appending mapping with certain suffix: `config.mappings.suffix_last` for

mappings which will use "prev" search method, `config.mappings.suffix_next`

- "next" search method.

Notes:

- It creates new mappings only for actions involving surrounding search:

delete, replace, find (right and left), highlight.

- All new mappings behave the same way as if `config.search_method` is set

to certain search method. They are dot-repeatable, respect |v:count|, etc.

- Supply empty string to disable creation of corresponding set of mappings.

Example with default values (`n` for `suffix_next`, `l` for `suffix_last`)

and initial line `(aa) (bb) (cc)`.

- Typing `sdn)` with cursor inside `(aa)` results into `(aa) bb (cc)`.

- Typing `sdl)` with cursor inside `(cc)` results into `(aa) bb (cc)`.

- Typing `2srn)]` with cursor inside `(aa)` results into `(aa) (bb) [cc]`.

`MiniSurround.highlight`()

Highlight surrounding

No need to use it directly, everything is setup in |MiniSurround.setup|.

------------------------------------------------------------------------------

*MiniSurround.update_n_lines()*

`MiniSurround.update_n_lines`()

Update `MiniSurround.config.n_lines`

Convenient wrapper for updating `MiniSurround.config.n_lines` in case the

default one is not appropriate.

------------------------------------------------------------------------------

*MiniSurround.user_input()*

`MiniSurround.user_input`({prompt}, {text})

Ask user for input

This is mainly a wrapper for |input()| which allows empty string as input,

cancelling with `<Esc>` and `<C-c>`, and slightly modifies prompt. Use it

to ask for input inside function custom surrounding (see |MiniSurround.config|).

------------------------------------------------------------------------------

*MiniSurround.gen_spec*

`MiniSurround.gen_spec`

Generate common surrounding specifications

This is a table with two sets of generator functions: <input> and <output>

(currently empty). Each is a table with values being function generating

corresponding surrounding specification.

Example: >

local ts_input = require('mini.surround').gen_spec.input.treesitter

require('mini.surround').setup({

custom_surroundings = {

-- Use tree-sitter to search for function call

f = {

input = ts_input({ outer = '@call.outer', inner = '@call.inner' })

}

})
