Returns 1 if {feature} is supported, 0 otherwise. The {feature} argument is a feature name like "nvim-0.2.1" or "win32", see below. See also |exists()|.

If the code has a syntax error, then Nvim may skip the rest of the line and miss |:endif|. if has('feature') | let x = this->breaks->without->the->feature | endif

Put |:if| and |:endif| on separate lines to avoid the syntax error. if has('feature') let x = this->breaks->without->the->feature endif

Vim's compile-time feature-names (prefixed with "+") are not recognized because Nvim is always compiled with all possible features. |feature-compile|

Feature names can be:

1. Nvim version. For example the "nvim-0.2.1" feature means that Nvim is version 0.2.1 or later: :if has("nvim-0.2.1")

2. Runtime condition or other pseudo-feature. For example the "win32" feature checks if the current system is Windows: :if has("win32") feature-list List of supported pseudo-feature names: acl |ACL| support. bsd BSD system (not macOS, use "mac" for that). clipboard |clipboard| provider is available. fname_case Case in file names matters (for Darwin and MS-Windows this is not present). iconv Can use |iconv()| for conversion. linux Linux system. mac MacOS system. nvim This is Nvim. python3 Legacy Vim |python3| interface. |has-python| pythonx Legacy Vim |python_x| interface. |has-pythonx| sun SunOS system. ttyin input is a terminal (tty). ttyout output is a terminal (tty). unix Unix system. vim_starting True during |startup|. win32 Windows system (32 or 64 bit). win64 Windows system (64 bit). wsl WSL (Windows Subsystem for Linux) system.

   					*has-patch*
   

3. Vim patch. For example the "patch123" feature means that Vim patch 123 at the current |v:version| was included: :if v:version > 602 || v:version == 602 && has("patch148")

4. Vim version. For example the "patch-7.4.237" feature means that Nvim is Vim-compatible to version 7.4.237 or later. :if has("patch-7.4.237")
