fix(window): don't add a hsep when out of room if global stl is off

Problem: a horizontal separator may be added to a window that doesn't need one
if there is no room when moving a different window.

Solution: only restore a hsep in winframe_restore when the global statusline is
enabled.

 4. If treesitter parsers are not bundled, they need to be available in a `parser/` runtime directory (e.g. `/usr/share/nvim/runtime/parser/`).
 
+### How to build static binary (on Linux)
+
+1. Use a linux distribution which uses musl C. We will use Alpine Linux but any distro with musl should work. (glibc does not support static linking)
+2. Run make passing the `STATIC_BUILD` variable: `make CMAKE_EXTRA_FLAGS="-DSTATIC_BUILD=1"`
+
+In case you are not using Alpine Linux you can use a container to do the build the binary:
+
+```bash
+podman run \
+  --rm \
+  -it \
+  -v "$PWD:/workdir" \
+  -w /workdir \
+  alpine:latest \
+  bash -c 'apk add build-base cmake coreutils curl gettext-tiny-dev && make CMAKE_EXTRA_FLAGS="-DSTATIC_BUILD=1"'
+```
+
+The resulting binary in `build/bin/nvim` will have all the dependencies statically linked:

+```

 Lua module: vim.lsp.log                                              *lsp-log*
 
+The `vim.lsp.log` module provides logging for the Nvim LSP client.
+
+When debugging language servers, it is helpful to enable extra-verbose logging
+of the LSP client RPC events. Example: >lua
+    vim.lsp.set_log_level 'trace'
+    require('vim.lsp.log').set_format_func(vim.inspect)
+<
+
+Then try to run the language server, and open the log with: >vim
+    :lua vim.cmd('tabnew ' .. vim.lsp.get_log_path())
+<
+
+(Or use `:LspLog` if you have nvim-lspconfig installed.)
+
+Note:
+• Remember to DISABLE verbose logging ("debug" or "trace" level), else you may
+  encounter performance issues.
+• "ERROR" messages containing "stderr" only indicate that the log was sent to
+  stderr. Many servers send harmless messages via stderr.
+

+Introduction                                                       *lua-plugin*
+
+This document provides guidance for developing Nvim (Lua) plugins:
+
+See |lua-guide| for guidance on using Lua to configure and operate Nvim.
+See |luaref| and |lua-concepts| for details on the Lua programming language.
+
+==============================================================================
+Creating your first plugin                                    *lua-plugin-new*
+
+Any Vimscript or Lua code file that lives in the right directory,
+automatically is a "plugin". There's no maniest or "registration" required.
+
+You can try it right now:
+
+1. Visit your config directory: >
+    :exe 'edit' stdpath('config')
+<
+2. Create a `plugin/foo.lua` file in there.
+3. Add something to it, like: >lua
+    vim.print('Hello World')
+<
+4. Start `nvim` and notice that it prints "Hello World" in the messages area.
+   Check `:messages` if you don't see it.
+
+Besides `plugin/foo.lua`, which is always run at startup, you can define Lua
+modules in the `lua/` directory. Those modules aren't loaded until your
+`plugin/foo.lua`, the user, calls `require(…)`.
+
+==============================================================================
+Type safety                                            *lua-plugin-type-safety*
+
+Lua, as a dynamically typed language, is great for configuration. It provides
+virtually immediate feedback.
+But for larger projects, this can be a double-edged sword, leaving your plugin
+susceptible to unexpected bugs at the wrong time.
+
+You can leverage LuaCATS or "emmylua" annotations https://luals.github.io/wiki/annotations/
+along with lua-language-server ("LuaLS") https://luals.github.io/ to catch
+potential bugs in your CI before your plugin's users do. The Nvim codebase
+uses these annotations extensively.

+Keymaps                                                   *lua-plugin-keymaps*
+
+Avoid creating excessive keymaps automatically. Doing so can conflict with
+user |mapping|s.
+
+NOTE: An example for uncontroversial keymaps are buffer-local |mapping|s for
+      specific file types or floating windows, or <Plug> mappings.
+
+A common approach to allow keymap configuration is to define a declarative DSL
+https://en.wikipedia.org/wiki/Domain-specific_language via a `setup` function.
+
+However, doing so means that
+
+- You will have to implement and document it yourself.
+- Users will likely face inconsistencies if another plugin has a slightly
+  different DSL.
+- |init.lua| scripts that call such a `setup` function may throw an error if
+  the plugin is not installed or disabled.

+As an alternative, you can provide |<Plug>| mappings to allow users to define
+their own keymaps with |vim.keymap.set()|.
+
+- This requires one line of code in user configs.
+- Even if your plugin is not installed or disabled, creating the keymap won't
+  throw an error.
+
+Another option is to simply expose a Lua function or |user-commands|.
+
+Some benefits of |<Plug>| mappings are that you can
+
+- Enforce options like `expr = true`.
+- Use |vim.keymap|'s built-in mode handling to expose functionality only for
+  specific |map-modes|.
+- Handle different |map-modes| differently with a single mapping, without
+  adding mode checks to the underlying implementation.
+- Detect user-defined mappings through |hasmapto()| before creating defaults.
+
+Some benefits of exposing a Lua function are:
+
+- Extensibility, if the function takes an options table as an argument.
+- A cleaner UX, if there are many options and enumerating all combinations
+  of options would result in a lot of |<Plug>| mappings.
+
+NOTE: If your function takes an options table, users may still benefit
+      from |<Plug>| mappings for the most common combinations.

+KEYMAP EXAMPLE
+
+In your plugin:
+>lua
+    vim.keymap.set('n', '<Plug>(SayHello)', function()
+        print('Hello from normal mode')
+    end, { noremap = true })
+
+    vim.keymap.set('v', '<Plug>(SayHello)', function()
+        print('Hello from visual mode')
+    end, { noremap = true })

+Initialization                                               *lua-plugin-init*
+
+Newcomers to Lua plugin development will often put all initialization logic in
+a single `setup` function, which takes a table of options.
+If you do this, users will be forced to call this function in order to use
+your plugin, even if they are happy with the default configuration.
+
+Strictly separated configuration and smart initialization allow your plugin to
+work out of the box.
+
+NOTE: A well designed plugin has minimal impact on startup time. See also
+|lua-plugin-lazy|.
+
+Common approaches to a strictly separated configuration are:
+
+- A Lua function, e.g. `setup(opts)` or `configure(opts)`, which only overrides the
+  default configuration and does not contain any initialization logic.
+- A Vimscript compatible table (e.g. in the |vim.g| or |vim.b| namespace) that your
+  plugin reads from and validates at initialization time.
+  See also |lua-vim-variables|.
+
+Typically, automatic initialization logic is done in a |plugin| or |ftplugin|
+script. See also |'runtimepath'|.

+Lazy loading                                                 *lua-plugin-lazy*
+
+Some users like to micro-manage "lazy loading" of plugins by explicitly
+configuring which commands and key mappings load the plugin.
+
+Your plugin should not depend on every user micro-managing their configuration
+in such a way. Nvim has a mechanism for every plugin to do its own implicit
+lazy-loading (in Vimscript it's called |autoload|), via `autoload/`
+(Vimscript) and `lua/` (Lua). Plugin authors can provide "lazy loading" by
+providing a `plugin/<name>.lua` file which defines their commands and
+keymappings. This file should be small, and should not eagerly `require()` the
+rest of your plugin. Commands and mappings should do the `require()`.
+
+Guidance:
+
+- Plugins should arrange their "lazy" behavior once, instead of expecting every user to micromanage it.
+- Keep `plugin/<name>.lua` small, avoid eagerly calling `require()` on modules
+  until a command or mapping is actually used.
+
+------------------------------------------------------------------------------
+Defer require() calls                               *lua-plugin-defer-require*
+
+`plugin/<name>.lua` scripts (|plugin|) are eagerly run at startup; this is
+intentional, so that plugins can setup the (minimal) commands and keymappings
+that users will use to invoke the plugin. This also means these "plugin/"
+files should NOT eagerly `require` Lua modules.
+
+For example, instead of:
+>lua
+    local foo = require('foo')
+    vim.api.nvim_create_user_command('MyCommand', function()
+        foo.do_something()
+    end, { -- ... })
+<
+which calls `require('foo')` as soon as the module is loaded, you can
+lazy-load it by moving the `require` into the command's implementation:
+>lua
+    vim.api.nvim_create_user_command('MyCommand', function()
+        local foo = require('foo')
+        foo.do_something()
+    end, {
+      -- ...
+    })
+<
+Likewise, if a plugin uses a Lua module as an entrypoint, it should
+defer `require` calls too.
+
+NOTE: For a Vimscript alternative to `require`, see |autoload|.
+
+NOTE: If you are worried about eagerly creating user commands, autocommands or
+keymaps at startup: Plugin managers that provide abstractions for lazy-loading
+plugins on such events do the same amount of work. There is no performance
+benefit for users to define lazy-loading entrypoints in their configuration
+instead of plugins defining it in `plugin/<name>.lua`.
+
+NOTE: You can use |--startuptime| to |profile| the impact a plugin has on
+startup time.
+
+------------------------------------------------------------------------------
+Filetype-specific functionality                          *lua-plugin-filetype*
+
+Consider making use of 'filetype' for any functionality that is specific to
+a filetype, by putting the initialization logic in a `ftplugin/{filetype}.lua`
+script.
+
+FILETYPE EXAMPLE
+
+A plugin tailored to Rust development might have initialization in
+`ftplugin/rust.lua`:
+>lua
+    if not vim.g.loaded_my_rust_plugin then
+        -- Initialize
+    end
+    -- NOTE: Using `vim.g.loaded_` prevents the plugin from initializing twice
+    -- and allows users to prevent plugins from loading
+    -- (in both Lua and Vimscript).
+    vim.g.loaded_my_rust_plugin = true
+
+    local bufnr = vim.api.nvim_get_current_buf()
+    -- do something specific to this buffer,
+    -- e.g. add a |<Plug>| mapping or create a command
+    vim.keymap.set('n', '<Plug>(MyPluginBufferAction)', function()
+        print('Hello')
+    end, { noremap = true, buffer = bufnr, })

+Configuration                                              *lua-plugin-config*
+
+Once you have merged the default configuration with the user's config, you
+should validate configs.
+
+Validations could include:
+
+- Correct types, see |vim.validate()|
+- Unknown fields in the user config (e.g. due to typos).
+  This can be tricky to implement, and may be better suited for a |health|
+  check, to reduce overhead.
+
+==============================================================================
+Troubleshooting                                   *lua-plugin-troubleshooting*
+
+HEALTH
+
+Nvim's "health" framework gives plugins a simple way to report status checks
+to users. See |health-dev| for an example.
+
+Basically, this just means your plugin will have a `lua/{plugin}/health.lua`
+file. |:checkhealth| will automatically find this file when it runs.
+
+Some things to validate:
+
+- User configuration
+- Proper initialization
+- Presence of Lua dependencies (e.g. other plugins)
+- Presence of external dependencies
+
+MINIMAL CONFIG TEMPLATE
+
+It can be useful to provide a template for a minimal configuration, along with
+a guide on how to use it to reproduce issues.
+
+==============================================================================
+Versioning and releases                                *lua-plugin-versioning*
+
+Consider:
+
+- Use |vim.deprecate()| or a `---@deprecate` annotation when you need to
+  communicate a (future) breaking change or discourged practice.
+- Using SemVer https://semver.org/ tags and releases to properly communicate
+  bug fixes, new features, and breaking changes.
+- Automating versioning and releases in CI.
+- Publishing to luarocks https://luarocks.org, especially if your plugin
+  has dependencies or components that need to be built; or if it could be a
+  dependency for another plugin.

-Nvim automatically adjusts |package.path| and |package.cpath| according to the
-effective 'runtimepath' value. Adjustment happens whenever 'runtimepath' is
-changed. `package.path` is adjusted by simply appending `/lua/?.lua` and
-`/lua/?/init.lua` to each directory from 'runtimepath' (`/` is actually the
-first character of `package.config`).
-
-Similarly to |package.path|, modified directories from 'runtimepath' are also
-added to |package.cpath|. In this case, instead of appending `/lua/?.lua` and
-`/lua/?/init.lua` to each runtimepath, all unique `?`-containing suffixes of
-the existing |package.cpath| are used. Example:
-
-- 1. Given that
-   - 'runtimepath' contains `/foo/bar,/xxx;yyy/baz,/abc`;
-   - initial |package.cpath| (defined at compile-time or derived from
-     `$LUA_CPATH` / `$LUA_INIT`) contains `./?.so;/def/ghi/a?d/j/g.elf;/def/?.so`.
-- 2. It finds `?`-containing suffixes `/?.so`, `/a?d/j/g.elf` and `/?.so`, in
-     order: parts of the path starting from the first path component containing
-     question mark and preceding path separator.
-- 3. The suffix of `/def/?.so`, namely `/?.so` is not unique, as it’s the same
-     as the suffix of the first path from |package.path| (i.e. `./?.so`). Which
-     leaves `/?.so` and `/a?d/j/g.elf`, in this order.
-- 4. 'runtimepath' has three paths: `/foo/bar`, `/xxx;yyy/baz` and `/abc`. The
-     second one contains a semicolon which is a paths separator so it is out,
-     leaving only `/foo/bar` and `/abc`, in order.
-- 5. The cartesian product of paths from 4. and suffixes from 3. is taken,
-     giving four variants. In each variant a `/lua` path segment is inserted
-     between path and suffix, leaving:
-     - `/foo/bar/lua/?.so`
-     - `/foo/bar/lua/a?d/j/g.elf`
-     - `/abc/lua/?.so`
-     - `/abc/lua/a?d/j/g.elf`
-- 6. New paths are prepended to the original |package.cpath|.
-
-The result will look like this: >
-
-    /foo/bar,/xxx;yyy/baz,/abc ('runtimepath')
-    × ./?.so;/def/ghi/a?d/j/g.elf;/def/?.so (package.cpath)
-    = /foo/bar/lua/?.so;/foo/bar/lua/a?d/j/g.elf;/abc/lua/?.so;/abc/lua/a?d/j/g.elf;./?.so;/def/ghi/a?d/j/g.elf;/def/?.so

-          \   },
-          \   'cache_enabled': 1,
-          \ }
+To configure a custom clipboard tool, set `g:clipboard` to a string name (from
+the above |clipboard-tool| list), or dict (to explicitly specify the shell
+commands or |lambda| functions).
 
 If "cache_enabled" is |TRUE| then when a selection is copied Nvim will cache
 the selection until the copy command process dies. When pasting, if the copy
 process has not died the cached selection is applied.
 
-g:clipboard can also use functions (see |lambda|) instead of strings.
-For example this configuration uses the g:foo variable as a fake clipboard:
->vim
-
-    let g:clipboard = {
-          \   'name': 'myClipboard',
-          \   'copy': {
-          \      '+': {lines, regtype -> extend(g:, {'foo': [lines, regtype]}) },

 The "copy" function stores a list of lines and the register type. The "paste"
 function returns the clipboard as a `[lines, regtype]` list, where `lines` is
 a list of lines and `regtype` is a register type conforming to |setreg()|.

--- Logger for language client plugin.
+--- @brief
+--- The `vim.lsp.log` module provides logging for the Nvim LSP client.
+---
+--- When debugging language servers, it is helpful to enable extra-verbose logging of the LSP client
+--- RPC events. Example:
+--- ```lua
+--- vim.lsp.set_log_level 'trace'
+--- require('vim.lsp.log').set_format_func(vim.inspect)
+--- ```
+---
+--- Then try to run the language server, and open the log with:
+--- ```vim
+--- :lua vim.cmd('tabnew ' .. vim.lsp.get_log_path())
+--- ```
+---
+--- (Or use `:LspLog` if you have nvim-lspconfig installed.)
+---
+--- Note:
+--- - Remember to DISABLE verbose logging ("debug" or "trace" level), else you may encounter
+---   performance issues.
+--- - "ERROR" messages containing "stderr" only indicate that the log was sent to stderr. Many
+---   servers send harmless messages via stderr.
