--- *mini.visits* Track and reuse file system visits
--- *MiniVisits*
---
--- MIT License Copyright (c) 2023 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Features:
<
10BC8
/div>---
--- - Persistently track file system visits (both files and directories)
--- per project directory. Store visit index is human readable and editable.
---
--- - Visit index is normalized on every write to contain relevant information.
--- Exact details can be customized. See |MiniVisits.normalize()|.
---
--- - Built-in ability to persistently add labels to path for later use.
--- See |MiniVisits.add_label()| and |MiniVisits.remove_label()|.
---
--- - Exported functions to reuse visit data:
--- - List visited paths/labels with custom filter and sort (uses "robust
--- frecency" by default). Can be used as source for pickers.
--- See |MiniVisits.list_paths()| and |MiniVisits.list_labels()|.
--- See |MiniVisits.gen_filter| and |MiniVisits.gen_sort|.
---
--- - Select visited paths/labels using |vim.ui.select()|.
--- See |MiniVisits.select_path()| and |MiniVisits.select_label()|.
---
--- - Iterate through visit paths in target direction ("forward", "backward",
--- "first", "last"). See |MiniVisits.iterate_paths()|.
---
--- - Exported functions to manually update visit index allowing persistent
--- track of any user information. See `*_index()` functions.
---
--- Notes:
--- - All data is stored _only_ in in-session Lua variable (for quick operation)
--- and at `config.store.path` on disk (for persistent usage).
--- - Most of functions affect an in-session data which gets written to disk only
--- before Neovim is closing or when users asks to.
--- - It doesn't account for paths being renamed or moved (because there is no
--- general way to detect that). Usually a manual intervention to the visit
--- index is required after the change but _before_ the next writing to disk
--- (usually before closing current session) because it will treat previous
--- path as deleted and remove it from index.
--- There is a |MiniVisits.rename_in_index()| helper for that.
--- If rename/move is done with |MiniFiles|, index is autoupdated.
---
--- Sources with more details:
--- - |MiniVisits-overview|
--- - |MiniVisits-index-specification|
--- - |MiniVisits-examples|
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.visits').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniVisits`
--- which you can use for scripting or manually (with `:lua MiniVisits.*`).
---
--- See |MiniVisits.config| for `config` structure and default values.
---
--- You can override runtime config settings locally to buffer inside
--- `vim.b.minivisits_config` which should have same structure as
--- `MiniVisits.config`. See |mini.nvim-buffer-local-config| for more details.
---
--- # Comparisons ~
---
--- - 'nvim-telescope/telescope-frecency.nvim':
--- - It stores array of actual visit timestamps, while this module tracks
--- only total number and latest timestamp of visits. This is by design
--- as a different trade-off between how much data is being used/stored
--- and complexity of underlying "frecency" sorting.
--- - By default tracks a buffer only once per session, while this module
--- tracks on every meaningful buffer enter. This leads to a more relevant
--- in-session sorting.
--- - Implements an original frecency algorithm of Firefox's address bar,
--- while this module uses own "robust frecency" approach.
--- - Mostly designed to work with 'nvim-telescope/telescope.nvim', while
--- this module provides general function to list paths and select
--- with |vim.ui.select()|.
--- - Does not allow use of custom data (like labels), while this module does.
---
--- - 'ThePrimeagen/harpoon':
--- - Has slightly different concept than general labeling, which more
--- resembles adding paths to an ordered stack. This module implements
--- a more common labeling which does not imply order with ability to
--- make it automated depending on the task and/or preference.
--- - Implements marks as positions in a path, while this module labels paths.
--- - Writes data on disk after every meaning change, while this module is
--- more conservative and read only when Neovim closes or when asked to.
--- - Has support for labeling terminals, while this modules is oriented
--- only towards paths.
--- - Has dedicated UI to manage marks, while this module does not by design.
--- There are functions for adding and removing label from the path.
--- - Does not provide functionality to track and reuse any visited path,
--- while this module does.
---
--- # Disabling ~
---
--- To disable automated tracking, set `vim.g.minivisits_disable` (globally) or
--- `vim.b.minivisits_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.
--- # Tracking visits ~
---
--- File system visits (both directory and files) tracking is done in two steps:
--- - On every dedicated event (`config.track.event`, |BufEnter| by default) timer
--- is (re)started to actually register visit after certain amount of time
--- (`config.track.delay` milliseconds, 1000 by default). It is not registered
--- immediately to allow navigation to target buffer in several steps
--- (for example, with series of |:bnext| / |:bprevious|).
---
--- - When delay time passes without any dedicated events being triggered
--- (meaning user is "settled" on certain buffer), |MiniVisits.register_visit()|
--- is called if all of the following conditions are met:
--- - Module is not disabled (see "Disabling" section in |MiniVisits|).
--- - Buffer is normal with non-empty name (used as visit path).
--- - Visit path does not equal to the latest tracked one. This is to allow
--- temporary enter of non-normal buffers (like help, terminal, etc.)
--- without artificial increase of visit count.
---
--- Visit is autoregistered for |current-directory| and leads to increase of count
--- and latest time of visit. See |MiniVisits-index-specification| for more details.
---
--- Notes:
--- - All data is stored _only_ in in-session Lua variable (for quick operation)
--- and at `config.store.path` on disk (for persistent usage). It is automatically
--- written to disk before every Neovim exit (if `config.store.autowrite` is set).
---
--- - Tracking can be disabled by supplying empty string as `track.event`.
--- Then it is up to the user to properly call |MiniVisits.register_visit()|.
---
--- # Reusing visits ~
---
--- Visit data can be reused in at least these ways:
---
--- - Get a list of visited paths (see |MiniVisits.list_paths()|) and use it
--- to visualize/pick/navigate visit history.
---
--- - Select one of the visited paths to open it (see |MiniVisits.select_path()|).
---
--- - Move along visit history (see |MiniVisits.iterate_paths()|).
---
--- - Utilize labels. Any visit can be added one or more labels (like "core",
--- "tmp", etc.). They are bound to the visit (path registered for certain
--- directory) and are stored persistently.
--- Labels can be used to manually create groups of files and/or directories
--- that have particular interest to the user.
--- There is no one right way to use them, though. See |MiniVisits-examples|
--- for some inspiration.
---
--- - Utilizing custom data. Visit index can be manipulated manually using
--- `_index()` set of functions. All "storable" (i.e. not functions or
--- metatables) user data inside index is then stored on disk, so it can be
--- used to create any kind of workflow user wants.
---
--- See |MiniVisits-examples| for some actual configuration and workflow examples.
---@tag MiniVisits-overview
--- # Structure ~
---
--- Visit index is a table containing actual data in two level deep nested tables.
---
--- First level keys are paths of project directory (a.k.a "cwd") for which
--- visits are registered.
---
--- Second level keys are actual visit paths. Their values are tables with visit
--- data which should follow these requirements:
--- - Field <count> should be present and be a number. It represents the number
--- of times this path was visited under particular cwd.
--- - Field <latest> should be present and be a number. It represents the time
--- of latest path visit under particular cwd.
--- By default computed with |os.time()| (up to a second).
--- - Field <labels> might not be present. If present, it should be a table
--- with string labels as keys and `true` as values. It represents labels of
--- the path under particular cwd.
---
--- Notes:
--- - All paths are absolute.
--- - Visit path should not necessarily be a part of corresponding cwd.
--- - Both `count` and `latest` can be any number: whole, fractional, negative, etc.
---
--- Example of an index data: >lua
---
--- {
--- ['/home/user/project_1'] = {
--- ['home/user/project_1/file'] = { count = 3, latest = 1699796000 },
--- ['home/user/project_1/subdir'] = {
--- count = 10, latest = 1699797000, labels = { core = true },
--- },
--- },
--- ['/home/user/project_2'] = {
--- ['home/user/project_1/file'] = {
--- count = 0, latest = 0, labels = { other = true },
--- },
--- ['home/user/project_2/README'] = { count = 1, latest = 1699798000 },
--- },
--- }

--- # Storage ~
---
--- When stored on disk, visit index is a file containing Lua code returning
--- visit index table. It can be edited by hand as long as it contains a valid
--- Lua code (to be executed with |dofile()|).
---
--- Notes:
--- - Storage is implemented in such a way that it doesn't really support more
--- than one parallel Neovim processes. Meaning that if there are two or more
--- simultaneous Neovim processes with same visit index storage path, the last
--- one writing to it will preserve its visit history while others - won't.
---
--- # Normalization ~
---
--- To ensure that visit index contains mostly relevant data, it gets normalized:
--- automatically inside |MiniVisits.write_index()| or via |MiniVisits.normalize()|.
---
--- What normalization actually does can be configured in `config.store.normalize`.
---
--- See |MiniVisits.gen_normalize.default()| for default normalization approach.
---@tag MiniVisits-index-specification
--- # Workflow examples ~
---
--- This module provides a flexible framework for working with file system visits.
--- Exact choice of how to organize workflow is left to the user.
--- Here are some examples for inspiration which can be combined together.
---
--- ## Use different sorting ~
---
--- Default sorting in |MiniVisits.gen_sort.default()| allows flexible adjustment
--- of which feature to prefer more: recency or frequency. Here is an example of
--- how to make set of keymaps for three types of sorting combined with two types
--- of scopes (all visits and only for current cwd): >lua
---
--- local make_select_path = function(select_global, recency_weight)
--- local visits = require('mini.visits')
--- local sort = visits.gen_sort.default({ recency_weight = recency_weight })
--- local select_opts = { sort = sort }
--- return function()
--- local cwd = select_global and '' or vim.fn.getcwd()
--- visits.select_path(cwd, select_opts)
--- end
--- end
---
--- local map = function(lhs, desc, ...)
--- vim.keymap.set('n', lhs, make_select_path(...), { desc = desc })
--- end
---
--- -- Adjust LHS and description to your liking
--- map('<Leader>vr', 'Select recent (all)', true, 1)
--- map('<Leader>vR', 'Select recent (cwd)', false, 1)
--- map('<Leader>vy', 'Select frecent (all)', true, 0.5)
--- map('<Leader>vY', 'Select frecent (cwd)', false, 0.5)
--- map('<Leader>vf', 'Select frequent (all)', true, 0)
--- map('<Leader>vF', 'Select frequent (cwd)', false, 0)
--- <
--- Note: If you have |MiniPick|, consider using |MiniExtra.pickers.visit_paths()|.
---
--- ## Use manual labels ~
---
--- Labels is a powerful tool to create groups of associated paths.
--- Usual workflow consists of:
--- - Add label with |MiniVisits.add_label()| (prompts for actual label).
--- - Remove label with |MiniVisits.remove_label()| (prompts for actual label).
--- - When need to use labeled groups, call |MiniVisits.select_label()| which
--- will then call |MiniVisits.select_path()| to select path among those
--- having selected label.
--- Note: If you have |MiniPick|, consider using |MiniExtra.pickers.visit_labels()|.
---
--- To make this workflow smoother, here is an example of keymaps: >lua
---
--- local map_vis = function(keys, call, desc)
--- local rhs = '<Cmd>lua MiniVisits.' .. call .. '<CR>'
--- vim.keymap.set('n', '<Leader>' .. keys, rhs, { desc = desc })
--- end
---
--- map_vis('vv', 'add_label()', 'Add label')
--- map_vis('vV', 'remove_label()', 'Remove label')
--- map_vis('vl', 'select_label("", "")', 'Select label (all)')
--- map_vis('vL', 'select_label()', 'Select label (cwd)')
--- <
--- ## Use fixed labels ~
---
--- During work on every project there is usually a handful of files where core
--- activity is concentrated. This can be made easier by creating mappings
--- which add/remove special fixed label (for example, "core") and select paths
--- with that label for both all and current cwd. Example: >lua
---
--- -- Create and select
--- local map_vis = function(keys, call, desc)
--- local rhs = '<Cmd>lua MiniVisits.' .. call .. '<CR>'
--- vim.keymap.set('n', '<Leader>' .. keys, rhs, { desc = desc })
--- end
---
--- map_vis('vv', 'add_label("core")', 'Add to core')
--- map_vis('vV', 'remove_label("core")', 'Remove from core')
--- map_vis('vc', 'select_path("", { filter = "core" })', 'Select core (all)')
--- map_vis('vC', 'select_path(nil, { filter = "core" })', 'Select core (cwd)')
---
--- -- Iterate based on recency
--- local sort_latest = MiniVisits.gen_sort.default({ recency_weight = 1 })
--- local map_iterate_core = function(lhs, direction, desc)
--- local opts = { filter = 'core', sort = sort_latest, wrap = true }
--- local rhs = function()
--- MiniVisits.iterate_paths(direction, vim.fn.getcwd(), opts)
--- end
--- vim.keymap.set('n', lhs, rhs, { desc = desc })
--- end
---
--- map_iterate_core('[{', 'last', 'Core label (earliest)')
--- map_iterate_core('[[', 'forward', 'Core label (earlier)')
--- map_iterate_core(']]', 'backward', 'Core label (later)')
--- map_iterate_core(']}', 'first', 'Core label (latest)')
--- <
--- ## Use automated labels ~
---
--- When using version control system (such as Git), usually there is already
--- an identifier that groups files you are working with - branch name.
--- Here is an example of keymaps to add/remove label equal to branch name: >lua
---
--- local map_branch = function(keys, action, desc)
--- local rhs = function()
--- local branch = vim.fn.system('git rev-parse --abbrev-ref HEAD')
--- if vim.v.shell_error ~= 0 then return nil end
--- branch = vim.trim(branch)
--- require('mini.visits')[action](branch)
--- end
--- vim.keymap.set('n', '<Leader>' .. keys, rhs, { desc = desc })
--- end
---
--- map_branch('vb', 'add_label', 'Add branch label')
--- map_branch('vB', 'remove_label', 'Remove branch label')
--- <

--- Module config
---
--- Default values:
---@eval return MiniDoc.afterlines_to_code(MiniDoc.current.eval_section)
---@text *MiniVisits.config.list*
--- # List ~
---
--- `config.list` defines how visit index is converted to a path list by default.
---
--- `list.filter` is a callable which should take a path data and return `true` if
--- this path should be present in the list.
--- Default: output of |MiniVisits.gen_filter.default()|.
---
--- Path data is a table with at least these fields:
--- - <path> `(string)` - absolute path of visit.
--- - <count> `(number)` - number of visits.
--- - <latest> `(number)` - timestamp of latest visit.
--- - <labels> `(table|nil)` - table of labels (has string keys with `true` values).
---
--- Notes:
--- - Both `count` and `latest` (in theory) can be any number. But built-in tracking
--- results into positive integer `count` and `latest` coming from |os.time()|.
--- - There can be other entries if they are set by user as index entry.
---
--- `list.sort` is a callable which should take an array of path data and return
--- a sorted array of path data (or at least tables each containing <path> field).
--- Default: output of |MiniVisits.gen_sort.default()|.
--- Single path data entry is a table with a same structure as for `list.filter`.
---
--- Note, that `list.sort` can be used both to filter, sort, or even return paths
--- unrelated to the input.
---
--- # Silent ~
---
--- `config.silent` is a boolean controlling whether to show non-error feedback
--- (like adding/removing labels, etc.). Default: `false`.
---
--- # Store ~
---
--- `config.store` defines how visit index is stored on disk to enable persistent
--- data across several sessions.
---
--- `store.autowrite` is a boolean controlling whether to write visit data to
--- disk on |VimLeavePre| event. Default: `true`.
---
--- `store.normalize` is a callable which should take visit index
--- (see |MiniVisits-index-specification|) as input and return "normalized" visit
--- index as output. This is used to ensure that visit index is up to date and
--- contains only relevant data. For example, it controls how old and
--- irrelevant visits are "forgotten", and more.
--- Default: output of |MiniVisits.gen_normalize.default()|.
---
--- `store.path` is a path to which visit index is written. See "Storage" section
--- of |MiniVisits-index-specification| for more details.
--- Note: set to empty string to disable any writing with not explicitly set
--- path (including the one on |VimLeavePre|).
--- Default: "mini-visits-index" file inside |$XDG_DATA_HOME|.
---
--- # Track ~
---
--- `config.track` defines how visits are tracked (index entry is autoupdated).
--- See "Tracking visits" section in |MiniVisits-overview| for more details.
---
--- `track.event` is a proper Neovim |{event}| on which track get triggered.
--- Note: set to empty string to disable automated tracking.
--- Default: |BufEnter|.
---
--- `track.delay` is a delay in milliseconds after event is triggered and visit
--- is autoregistered.
--- Default: 1000 (to allow navigation between buffers without tracking
--- intermediate ones).

--- Iterate visit paths
---
--- Steps:
--- - Compute a sorted array of target paths using |MiniVisits.list_paths()|.
--- - Identify the current index inside the array based on path of current buffer.
--- - Iterate through the array certain amount of times in a dedicated direction:
--- - For "first" direction - forward starting from index 0 (so that single
--- first iteration leads to first path).
--- - For "backward" direction - backward starting from current index.
--- - For "forward" direction - forward starting from current index.
--- - For "last" direction - backward starting from index after the last one
--- (so that single first iteration leads to the last path).
---
--- Notes:
--- - Mostly designed to be used as a mapping. See `MiniVisits-examples`.
--- - If path from current buffer is not in the output of `MiniVisits.list_paths()`,
--- starting index is inferred such that first iteration lands on first item
--- (if iterating forward) or last item (if iterating backward).
--- - Navigation with this function is not tracked (see |MiniVisits-overview|).
--- This is done to allow consecutive application without affecting
--- underlying list of paths.
---
--- Examples assuming underlying array of files `{ "file1", "file2", "file3" }`:
---
--- - `MiniVisits("first")` results into focusing on "file1".
--- - `MiniVisits("backward", { n_times = 2 })` from "file3" results into "file1".
--- - `MiniVisits("forward", { n_times = 10 })` from "file1" results into "file3".
--- - `MiniVisits("last", { n_times = 4, wrap = true })` results into "file3".

--- Rename path in index
---
--- A helper to react for a path rename/move in order to preserve its visit data.
--- It works both for file and directory paths.
---
--- Notes:
--- - It does not update current index, but returns a modified index object.
--- Use |MiniVisits.set_index()| to make it current.
--- - Use only full paths.
--- - Do not append `/` to directory paths. Use same format as for files.
---
--- Assuming `path_from` and `path_to` are variables containing full paths
--- before and after rename/move, here is an example to update current index: >lua
---
--- local new_index = MiniVisits.rename_in_index(path_from, path_to)
--- MiniVisits.set_index(new_index)
--- <
---@param path_from string Full path to be renamed.
---@param path_to string Full path to be replaced with.
---@param index table|nil Index object inside which to perform renaming.
--- Default: current session index.
---
---@return table Index object with renamed path.
