---herdr-splits.nvim — Seamless navigation and resizing between Neovim splits
---and Herdr panes. Makes Herdr terminal splits behave like native Neovim windows.
---
---Usage:
--- require('herdr-splits').setup({ ... })
--- vim.keymap.set('n', '<C-h>', require('herdr-splits').move_cursor_left)
--- vim.keymap.set('n', '<M-h>', require('herdr-splits').resize_left)
local config = require('herdr-splits.config')
local nav = require('herdr-splits.nav')
local resize_mod = require('herdr-splits.resize')
local win = require('herdr-splits.win')
local sync = require('herdr-splits.sync')
local M = {}
---Apply configuration. Idempotent — calling again merges into existing config.
---@param opts table|nil Configuration options (see config.lua for defaults)
function M.setup(opts)
config.setup(opts)
pcall(sync.sync)
end
---Sync the Herdr-managed checkout to match this lazy commit.
---Intended as a lazy.nvim `build` hook entry point; respects `auto_sync_herdr`.
---Safe to call at any time; no-op unless opted in.
function M.sync_herdr()
pcall(sync.sync)

---Resize the current split to the left.
---Amount defaults to config.default_amount. Multiplied by vim.v.count1.
