*MiniMisc*
MIT License Copyright (c) 2021 Evgeni Chasnovski
==============================================================================
Features the following functions:
- |MiniMisc.bench_time()| to benchmark function execution time.
Useful in combination with `stat_summary()`.
- |MiniMisc.put()| and |MiniMisc.put_text()| to pretty print its arguments
into command line and current buffer respectively.
- |MiniMisc.setup_auto_root()| to set up automated change of current directory.
- |MiniMisc.setup_restore_cursor()| to set up automated restoration of
cursor position on file reopen.
- |MiniMisc.stat_summary()| to compute summary statistics of numerical array.
Useful in combination with `bench_time()`.
- |MiniMisc.tbl_head()| and |MiniMisc.tbl_tail()| to return "first" and "last"
elements of table.
- |MiniMisc.zoom()| to zoom in and out of a buffer, making it full screen
in a floating window.
- And more.
# Setup ~
This module doesn't need setup, but it can be done to improve usability.
Setup with `require('mini.misc').setup({})` (replace `{}` with your
`config` table). It will create global Lua table `MiniMisc` which you can
use for scripting or manually (with `:lua MiniMisc.*`).
See |MiniMisc.config| for `config` structure and default values.
This module doesn't have runtime options, so using `vim.b.minimisc_config`
will have no effect here.
------------------------------------------------------------------------------
*MiniMisc.setup()*
`MiniMisc.setup`({config})
Module setup
Parameters ~
{config} `(table|nil)` Module config table. See |MiniMisc.config|.
Usage ~
>lua
require('mini.misc').setup() -- use default config
-- OR
require('mini.misc').setup({}) -- replace {} with your config table
<
------------------------------------------------------------------------------
*MiniMisc.config*
`MiniMisc.config`
Module config
Default values:
>lua
MiniMisc.config = {
-- Array of fields to make global (to be used as independent variables)
make_global = { 'put', 'put_text' },
}
<
------------------------------------------------------------------------------
*MiniMisc.bench_time()*
`MiniMisc.bench_time`({f}, {n}, {...})
Execute `f` several times and time how long it took
Parameters ~
{f} `(function)` Function which execution to benchmark.
{n} `(number|nil)` Number of times to execute `f(...)`. Default: 1.
{...} `(any)` Arguments when calling `f`.
Return ~
`(...)` Table with durations (in seconds; up to nanoseconds) and
output of (last) function execution.
------------------------------------------------------------------------------
*MiniMisc.get_gutter_width()*
`MiniMisc.get_gutter_width`({win_id})
Compute width of gutter (info column on the left of the window)
Parameters ~
{win_id} `(number|nil)` Window identifier (see |win_getid()|) for which gutter
width is computed. Default: 0 for current.
------------------------------------------------------------------------------
*MiniMisc.put()*
`MiniMisc.put`({...})
Print Lua objects in command line
Parameters ~
{...} `(any)` Any number of objects to be printed each on separate line.
------------------------------------------------------------------------------
*MiniMisc.put_text()*
`MiniMisc.put_text`({...})
Print Lua objects in current buffer
Parameters ~
{...} `(any)` Any number of objects to be printed each on separate line.
------------------------------------------------------------------------------
*MiniMisc.resize_window()*
`MiniMisc.resize_window`({win_id}, {text_width})
Resize window to have exact number of editable columns
Parameters ~
{win_id} `(number|nil)` Window identifier (see |win_getid()|) to be resized.
Default: 0 for current.
{text_width} `(number|nil)` Number of editable columns resized window will
display. Default: first element of 'colorcolumn' or otherwise 'textwidth'
(using screen width as its default but not more than 79).
------------------------------------------------------------------------------
*MiniMisc.setup_auto_root()*
`MiniMisc.setup_auto_root`({names}, {fallback})
Set up automated change of current directory
What it does:
- Creates autocommand which on every |BufEnter| event with |MiniMisc.find_root()|
finds root directory for current buffer file and sets |current-directory|
to it (using |chdir()|).
- Resets |autochdir| to `false`.
Parameters ~
{names} `(table|function|nil)` Forwarded to |MiniMisc.find_root()|.
{fallback} `(function|nil)` Forwarded to |MiniMisc.find_root()|.
Usage ~
>lua
require('mini.misc').setup()
MiniMisc.setup_auto_root()
<
------------------------------------------------------------------------------
*MiniMisc.find_root()*
`MiniMisc.find_root`({buf_id}, {names}, {fallback})
Find root directory
Based on a buffer name (full path to file opened in a buffer) find a root
directory. If buffer is not associated with file, returns `nil`.
Root directory is a directory containing at least one of pre-defined files.
It is searched using |vim.fn.find()| with `upward = true` starting from
directory of current buffer file until first occurrence of root file(s).
Notes:
- Uses directory path caching to speed up computations. This means that no
changes in root directory will be detected after directory path was already
used in this function. Reload Neovim to account for that.
Parameters ~
{buf_id} `(number|nil)` Buffer identifier (see |bufnr()|) to use.
Default: 0 for current.
{names} `(table|function|nil)` Array of file names or a callable used to
identify a root directory. Forwarded to |vim.fs.find()|.
Default: `{ '.git', 'Makefile' }`.
{fallback} `(function|nil)` Callable fallback to use if no root is found
with |vim.fs.find()|. Will be called with a buffer path and should return
a valid directory path.
------------------------------------------------------------------------------
*MiniMisc.setup_restore_cursor()*
`MiniMisc.setup_restore_cursor`({opts})
Restore cursor position on file open
When reopening a file this will make sure the cursor is placed back to the
position where you left before. This implements |restore-cursor| in a nicer way.
File should have a recognized file type (see 'filetype') and be opened in
a normal buffer (see 'buftype').
Note: it relies on file mark data stored in 'shadafile' (see |shada-f|).
Be sure to enable it.
Parameters ~
{opts} `(table|nil)` Options for |MiniMisc.restore_cursor|. Possible fields:
- <center> - (boolean) Center the window after we restored the cursor.
Default: `true`.
- <ignore_filetype> - Array with file types to be ignored (see 'filetype').
Default: `{ "gitcommit", "gitrebase" }`.
Usage ~
>lua
require('mini.misc').setup_restore_cursor()
<
------------------------------------------------------------------------------
*MiniMisc.stat_summary()*
`MiniMisc.stat_summary`({t})
Compute summary statistics of numerical array
This might be useful to compute summary of time benchmarking with
|MiniMisc.bench_time|.
Parameters ~
{t} `(table)` Array (table suitable for `ipairs`) of numbers.
Return ~
`(table)` Table with summary values under following keys (may be
extended in the future): <maximum>, <mean>, <median>, <minimum>, <n>
(number of elements), <sd> (sample standard deviation).
------------------------------------------------------------------------------
*MiniMisc.tbl_head()*
`MiniMisc.tbl_head`({t}, {n})
Return "first" elements of table as decided by `pairs`
Note: order of elements might vary.
Parameters ~
{t} `(table)` Input table.
{n} `(number|nil)` Maximum number of first elements. Default: 5.
Return ~
`(table)` Table with at most `n` first elements of `t` (with same keys).
------------------------------------------------------------------------------
*MiniMisc.tbl_tail()*
`MiniMisc.tbl_tail`({t}, {n})
Return "last" elements of table as decided by `pairs`
This function makes two passes through elements of `t`:
- First to count number of elements.
- Second to construct result.
Note: order of elements might vary.
Parameters ~
{t} `(table)` Input table.
{n} `(number|nil)` Maximum number of last elements. Default: 5.
Return ~
`(table)` Table with at most `n` last elements of `t` (with same keys).
------------------------------------------------------------------------------
*MiniMisc.use_nested_comments()*
`MiniMisc.use_nested_comments`({buf_id})
Add possibility of nested comment leader
This works by parsing 'commentstring' buffer option, extracting
non-whitespace comment leader (symbols on the left of commented line), and
locally modifying 'comments' option (by prepending `n:<leader>`). Does
nothing if 'commentstring' is empty or has comment symbols both in front
and back (like "/*%s*/").
Nested comment leader added with this function is useful for formatting
nested comments. For example, have in Lua "first-level" comments with '--'
and "second-level" comments with '----'. With nested comment leader second
type can be formatted with `gq` in the same way as first one.
Recommended usage is with |autocmd|: >lua
local use_nested_comments = function() MiniMisc.use_nested_comments() end
vim.api.nvim_create_autocmd('BufEnter', { callback = use_nested_comments })
<
Note: for most filetypes 'commentstring' option is added only when buffer
with this filetype is entered, so using non-current `buf_id` can not lead
to desired effect.
Parameters ~
{buf_id} `(number|nil)` Buffer identifier (see |bufnr()|) in which function
will operate. Default: 0 for current.
------------------------------------------------------------------------------
*MiniMisc.zoom()*
`MiniMisc.zoom`({buf_id}, {config})
Zoom in and out of a buffer, making it full screen in a floating window
This function is useful when working with multiple windows but temporarily
needing to zoom into one to see more of the code from that buffer. Call it
again (without arguments) to zoom out.
Parameters ~
{buf_id} `(number|nil)` Buffer identifier (see |bufnr()|) to be zoomed.
Default: 0 for current.
{config} `(table|nil)` Optional config for window (as for |nvim_open_win()|).
