Configuration

This plugin has the usual setup method. Below are the defaults:

local filters = require('autosave.filters')
-- Available filters:
-- filters.git_repo
-- filters.invert
-- filters.opt 
-- filters.not_empty 
-- filters.modifiable 
-- filters.writeable 
-- filters.modified 
-- filters.filetype 
-- filters.custom 
-- Each filter has luadoc to describe its functionality and usage.
require('autosave').setup({
    plugin = {
        force = false, -- Whether to forcefully write or not (:w!)
    },
    events = {
        register = true, -- Should autosave register its autocommands
        triggers = { -- The autocommands to register, if enabled
            'InsertLeave', 'TextChanged'
        }
    },
    debounce = {
        enabled = true, -- Should debouncing be enabled
        delay = 250 -- If enabled, only save the file at most every `delay` ms
    },
    filters = { -- The filters to apply, see above for all options.
        -- These filters are required for basic operation as they prevent
        -- errors related to to buffer state.
        filters.writeable,
        filters.not_empty,
        filters.modified,
    },
    hooks = {
        on_enable = nil,   -- Called when the plugin is enabled for the first time.
        pre_filter = nil,  -- Called before the write sequence begins. (This happens before filter checks)
        pre_write = nil,   -- Called before the buffer is written (This happens after all checks pass)
        post_write = nil,  -- Called after the write sequence. (This happens after the buffer has been saved)
    }
})

Format on save

When using an on-save format solution with this plugin, special care needs to be taken to avoid errors or strange behaviour.

It is advised to put the formatting logic in the pre_write hook.

require('autosave').setup({
   hooks = {
       pre_write = function()
           vim.cmd [[ Neoformat ]]
       end
   }
})

Actions

This plugin exposes a Lua API for performing various actions. All actions require the plugin to have been setup with the setup() method, detailed above, to work properly.

local actions = require('autosave.actions')

actions.buf_enable()     -- Enable the plugin for the current buffer.
actions.buf_disable()    -- Disable the plugin for the current buffer.
actions.buf_toggle()     -- Toggle the plugin on or off for the current buffer.

actions.global_enable()  -- Enable the plugin globally.
actions.global_disable() -- Disable the plugin globally.
actions.global_toggle()  -- Toggle the plugin on or off globally.

actions.save()           -- Run the save sequence.
actions.show_status()    -- Display the status of the plugin.

Ex-commands

Each of the above actions has a corresponding ex-command, listed below.

:ASGlobalEnable -- Enable the plugin globally. :ASGlobalDisable -- Disable the plugin globally. :ASGlobalToggle -- Toggle the plugin on or off globally.

:ASEnable -- Enable the plugin for the current buffer.
