--- *mini.deps* Plugin manager
--- *MiniDeps*
---
--- MIT License Copyright (c) 2024 Evgeni Chasnovski
---
--- ==============================================================================
---
--- Features:
---
--- - Manage plugins utilizing Git and built-in |packages| with these actions:
--- - Add plugin to current session, download if absent. See |MiniDeps.add()|.
--- - Update with/without confirm, with/without parallel download of new data.
--- See |MiniDeps.update()|.
--- - Delete unused plugins with/without confirm. See |MiniDeps.clean()|.
--- - Get / set / save / load snapshot. See `MiniDeps.snap_*()` functions.
---
--- All main actions are available both as Lua functions and user commands
--- (see |MiniDeps-commands|).
---
--- - Minimal yet flexible plugin |MiniDeps-plugin-specification|:
--- - Plugin source.
--- - Name of target plugin directory.
--- - Checkout target: branch, commit, tag, etc.
--- - Monitor branch to track updates without checking out.
--- - Dependencies to be set up prior to the target plugin.
--- - Hooks to call before/after plugin is created/changed.
---
--- - Helpers implementing two-stage startup: |MiniDeps.now()| and |MiniDeps.later()|.
--- See |MiniDeps-overview| for how to implement basic lazy loading with them.
---
--- What it doesn't do:
---
--- - Manage plugins which are developed without Git. The suggested approach is
--- to create a separate package (see |packages|).
---
--- - Provide ways to completely remove or update plugin's functionality in
--- current session. Although this is partially doable, it can not be done
--- in full (yet) because plugins can have untraceable side effects
--- (autocmmands, mappings, etc.).
--- The suggested approach is to restart Nvim.
---
--- Sources with more details:
--- - |MiniDeps-overview|
--- - |MiniDeps-plugin-specification|
--- - |MiniDeps-commands|
---
--- # Dependencies ~
---
--- For most of its functionality this plugin relies on `git` CLI tool.
--- See https://git-scm.com/ for more information about how to install it.
--- Actual knowledge of Git is not required but helpful.
---
--- # Setup ~
---
--- This module needs a setup with `require('mini.deps').setup({})` (replace
--- `{}` with your `config` table). It will create global Lua table `MiniDeps`
--- which you can use for scripting or manually (with `:lua MiniDeps.*`).
---
--- See |MiniDeps.config| for `config` structure and default values.
---
--- You can override runtime config settings locally to buffer inside
--- `vim.b.minideps_config` which should have same structure as
--- `MiniDeps.config`. See |mini.nvim-buffer-local-config| for more details.
---
--- # Comparisons ~
---
--- - 'folke/lazy.nvim':
--- - More feature-rich and complex.
--- - Uses table specification with dedicated functions to add plugins,
--- while this module uses direct function call approach
--- (calling |MiniDeps.add()| ensures that plugin is usable).
--- - Uses version tags by default, while this module is more designed towards
--- tracking branches. Using tags is possible too (see |MiniDeps-overview|).
---
--- - 'savq/paq-nvim':
--- - Overall less feature-rich than this module (by design).
--- - Uses array of plugin specifications inside `setup()` call to define which
--- plugins should be installed. Requires separate `:PaqInstall` call to
--- actually install them. This module ensures installation on first load.
---
--- - 'junegunn/vim-plug':
--- - Written in Vimscript, while this module is in Lua.
--- - Similar approach to defining and installing plugins as 'savq/paq-nvim'.
--- - Has basic lazy-loading built-in, while this module does not (by design).
---
--- # Highlight groups ~
---
--- Highlight groups are used inside confirmation buffers after
--- default |MiniDeps.update()| and |MiniDeps.clean()|.
---
--- * `MiniDepsChangeAdded` - added change (commit) during update.
--- * `MiniDepsChangeRemoved` - removed change (commit) during update.
--- * `MiniDepsHint` - various hints.
--- * `MiniDepsInfo` - various information.
--- * `MiniDepsMsgBreaking` - message for (conventional commit) breaking change.
--- * `MiniDepsPlaceholder` - placeholder when there is no valuable information.
--- * `MiniDepsTitle` - various titles.
--- * `MiniDepsTitleError` - title when plugin had errors during update.
--- * `MiniDepsTitleSame` - title when plugin has no changes to update.
--- * `MiniDepsTitleUpdate` - title when plugin has changes to update.
---
--- To change any highlight group, modify it directly with |:highlight|.
--- # Directory structure ~
---
--- This module uses built-in |packages| to make plugins usable in current session.
--- It works with "pack/deps" package inside `config.path.package` directory.
---
--- By default "opt" subdirectory is used to install optional plugins which are
--- loaded on demand with |MiniDeps.add()|.
--- Non-optional plugins in "start" subdirectory are supported but only if moved
--- there manually after initial install. Use it if you know what you are doing.
---
--- # Add plugin ~
---
--- Use |MiniDeps.add()| to add plugin to current session. Supply plugin's URL
--- source as a string or |MiniDeps-plugin-specification| in general. If plugin is
--- not present in "pack/deps" package, it will be created (a.k.a. installed)
--- before processing anything else.
---
--- The recommended way of adding a plugin is by calling |MiniDeps.add()| in the
--- |init.lua| file (make sure |MiniDeps.setup()| is called prior): >lua
---
--- local add = MiniDeps.add
---
--- -- Add to current session (install if absent)
--- add({
--- source = 'neovim/nvim-lspconfig',
--- -- Supply dependencies near target plugin
--- depends = { 'williamboman/mason.nvim' },
--- })
---
--- add({
--- source = 'nvim-treesitter/nvim-treesitter',
--- -- Use 'master' while monitoring updates in 'main'
--- checkout = 'master',
--- monitor = 'main',
--- -- Perform action after every checkout
--- hooks = { post_checkout = function() vim.cmd('TSUpdate') end },
--- })
--- -- Possible to immediately execute code which depends on the added plugin
--- require('nvim-treesitter.configs').setup({
--- ensure_installed = { 'lua', 'vimdoc' },
--- highlight = { enable = true },
--- })
--- <
--- NOTE:
--- - To increase performance, `add()` only ensures presence on disk and
--- nothing else. In particular, it doesn't ensure `opts.checkout` state.
--- Update or modify plugin state explicitly (see later sections).
---
--- # Lazy loading ~
---
--- Any lazy-loading is assumed to be done manually by calling |MiniDeps.add()|
--- at appropriate time. This module provides helpers implementing special safe
--- two-stage loading:
--- - |MiniDeps.now()| safely executes code immediately. Use it to load plugins
--- with UI necessary to make initial screen draw.
--- - |MiniDeps.later()| schedules code to be safely executed later, preserving
--- order. Use it (with caution) for everything else which doesn't need
--- precisely timed effect, as it will be executed some time soon on one of
--- the next event loops. >lua
---
--- local now, later = MiniDeps.now, MiniDeps.later
---
--- -- Safely execute immediately
--- now(function() vim.cmd('colorscheme randomhue') end)
--- now(function() require('mini.statusline').setup() end)
---
--- -- Safely execute later
--- later(function() require('mini.pick').setup() end)
--- <
--- # Update ~
---
--- To update plugins from current session with new data from their sources,
--- use |:DepsUpdate|. This will download updates (utilizing multiple cores) and
--- show confirmation buffer. Follow instructions at its top to finish an update.
---
--- NOTE: This updates plugins on disk which most likely won't affect current
--- session. Restart Nvim to have them properly loaded.
---
--- # Modify ~
---
--- To change plugin's specification (like set different `checkout`, etc.):
--- - Update corresponding |MiniDeps.add()| call.
--- - Run `:DepsUpdateOffline <plugin_name>`.
--- - Review changes and confirm.
--- - Restart Nvim.
---
--- NOTE: if `add()` prior used a single source string, make sure to convert
--- its argument to `{ source = '<previous_argument>', checkout = '<state>'}`
---
--- # Snapshots ~
---
--- Use |:DepsSnapSave| to save state of all plugins from current session into
--- a snapshot file (see `config.path.snapshot`).
---
--- Use |:DepsSnapLoad| to load snapshot. This will change (without confirmation)
--- state on disk. Plugins present in both snapshot file and current session
--- will be affected. Restart Nvim to see the effect.
---
--- NOTE: loading snapshot does not change plugin's specification defined inside
--- |MiniDeps.add()| call. This means that next update might change plugin's state.
--- To make it permanent, freeze plugin in target state manually.
---
--- # Freeze ~
---
--- Modify plugin's specification to have `checkout` pointing to a static
--- target: tag, state (commit hash), or 'HEAD' (to freeze in current state).
---
--- Frozen plugins will not receive updates. You can monitor any new changes from
--- its source by "subscribing" to `monitor` branch which will be shown inside
--- confirmation buffer after |:DepsUpdate|.
---
--- Example: use `checkout = 'v0.10.0'` to freeze plugin at tag "v0.10.0" while
--- monitoring new versions in the log from `monitor` (usually default) branch.
---
--- # Rollback ~
---
--- To roll back after an unfortunate update:
--- - Get identifier of latest working state:
--- - Use |:DepsShowLog| to see update log, look for plugin's name, and copy
--- identifier listed as "State before:".
--- - See previously saved snapshot file for plugin's name and copy
--- identifier next to it.
--- - Freeze plugin at that state while monitoring appropriate branch.
--- Revert to previous shape of |MiniDeps.add()| call to resume updating.
---
--- # Remove ~
---
--- - Make sure that target plugin is not registered in current session.
--- Usually it means removing corresponding |MiniDeps.add()| call.
--- - Run |:DepsClean|. This will show confirmation buffer with a list of plugins to
--- be deleted from disk. Follow instructions at its top to finish cleaning.
---
--- Alternatively, manually delete plugin's directory from "pack/deps" package.
---@tag MiniDeps-overview
--- # Plugin specification ~
---
--- Each plugin dependency is managed based on its specification (a.k.a. "spec").
--- See |MiniDeps-overview| for some examples.
---
--- Specification can be a single string which is inferred as:
--- - Plugin <name> if it doesn't contain "/".
--- - Plugin <source> otherwise.
---
--- Primarily, specification is a table with the following fields:
---
--- - <source> `(string|nil)` - field with URI of plugin source used during creation
--- or update. Can be anything allowed by `git clone`.
--- Default: `nil` to rely on source set up during install.
--- Notes:
--- - It is required for creating plugin, but can be omitted afterwards.
--- - As the most common case, URI of the format "user/repo" is transformed
--- into "https://github.com/user/repo".
---
--- - <name> `(string|nil)` - directory basename of where to put plugin source.
--- It is put in "pack/deps/opt" subdirectory of `config.path.package`.
--- Default: basename of <source> if it is present, otherwise should be
--- provided explicitly.
---
--- - <checkout> `(string|nil)` - checkout target used to set state during update.
--- Can be anything supported by `git checkout` - branch, commit, tag, etc.
--- Default: `nil` for default branch (usually "main" or "master").
---
--- - <monitor> `(string|nil)` - monitor branch used to track new changes from
--- different target than `checkout`. Should be a name of present Git branch.
--- Default: `nil` for default branch (usually "main" or "master").
---
--- - <depends> `(table|nil)` - array of plugin specifications (strings or tables)
--- to be added prior to the target.
--- Default: `nil` for no dependencies.
---
--- - <hooks> `(table|nil)` - table with callable hooks to call on certain events.
--- Possible hook names:
--- - <pre_install> - before creating plugin directory.
--- - <post_install> - after creating plugin directory.
--- - <pre_checkout> - before making change in existing plugin.
--- - <post_checkout> - after making change in existing plugin.
--- Each hook is executed with the following table as an argument:
--- - <path> (`string`) - absolute path to plugin's directory
--- (might not yet exist on disk).
--- - <source> (`string`) - resolved <source> from spec.
--- - <name> (`string`) - resolved <name> from spec.
--- Default: `nil` for no hooks.
---@tag MiniDeps-plugin-specification
--- # User commands ~
---
--- Note: Most commands have a Lua function alternative which they rely on.
--- Like |:DepsAdd| uses |MiniDeps.add()|, etc.
---
--- *:DepsAdd*
--- `:DepsAdd user/repo` makes plugin from https://github.com/user/repo available
--- in the current session (also creates it, if it is not present).
--- `:DepsAdd name` adds already installed plugin `name` to current session.
--- Accepts only single string compatible with |MiniDeps-plugin-specification|.
--- To add plugin in every session, put |MiniDeps.add()| in |init.lua|.
---
--- *:DepsUpdate*
--- `:DepsUpdate` synchronizes plugins with their session specifications and
--- updates them with new changes from sources. It shows confirmation buffer in
--- a separate |tabpage| with information about an upcoming update to review
--- and (selectively) apply. See |MiniDeps.update()| for more info.
---
--- `:DepsUpdate name` updates plugin `name`. Any number of names is allowed.
---
--- `:DepsUpdate!` and `:DepsUpdate! name` update without confirmation.
--- You can see what was done in the log file afterwards (|:DepsShowLog|).
---
--- *:DepsUpdateOffline*
--- `:DepsUpdateOffline` is same as |:DepsUpdate| but doesn't download new updates
--- from sources. Useful to only synchronize plugin specification in code and
--- on disk without unnecessary downloads.
---
--- *:DepsShowLog*
--- `:DepsShowLog` opens log file to review.
---
--- *:DepsClean*
--- `:DepsClean` deletes plugins from disk not added to current session. It shows
--- confirmation buffer in a separate |tabpage| with information about an upcoming
--- deletes to review and (selectively) apply. See |MiniDeps.clean()| for more info.
---
--- `:DepsClean!` deletes plugins without confirmation.
---
--- *:DepsSnapSave*
--- `:DepsSnapSave` creates snapshot file in default location (see |MiniDeps.config|).
--- `:DepsSnapSave path` creates snapshot file at `path`.
---
--- *:DepsSnapLoad*
---
--- `:DepsSnapLoad` loads snapshot file from default location (see |MiniDeps.config|).
--- `:DepsSnapLoad path` loads snapshot file at `path`.
