INTRODUCTION						*tree-introduction*

*tree* is the neovim file explorer powered by C++.

==============================================================================
INSTALL							*tree-install*

Note: tree requires Neovim 0.5+.

1. Extract the files and put them in your Neovim config directory
   (usually `$XDG_CONFIG_HOME/nvim/`).

INTERFACE						*tree-interface*

------------------------------------------------------------------------------
COMMANDS 						*tree-commands*

:Tree [{options}] {paths}				*:Tree*
		Creates a new Tree buffer.

FUNCTIONS 						*tree-functions*

tree#action({action}[, {args}])				*tree#action()*
		Fire {action} action with {args} asynchronously.
		See |tree-actions|.
		{args} behavior depends on {action}.
		Note: It is only used to define mappings.
		Note: You cannot fire the next action until the previous
		action is finished.

							*tree.call_action()*
tree.call_action({action}[, {args}])
		Fire {action} action with {args}.  See |tree-actions|.
		{args} behavior depends on {action}.

						*tree.call_async_action()*
tree.call_async_action({action}[, {args}])
		Fire {action} action with {args} asynchronously.
		See |tree-actions|.
		{args} behavior depends on {action}.
		Note: You cannot fire the next action until the previous
		action is finished.

						*tree.custom_column()*
tree.custom_column({column-name}, {option-name}, {value})
tree.custom_column({column-name}, {dict})
		Set {column-name} column specialized variable {variable-name}
		to {value}.  You may specify multiple sources with the
		separator "," in {column-name}. >

	tree.custom_column('icon', {
	    directory_icon='▸',
	    opened_icon='▾',
	    root_icon=' ',
	})

	tree.custom_column('filename', {
	    min_width=40,

	    readonly_icon='✗',
	    selected_icon='✓',
	})
<
						*tree.custom_option()*
tree.custom_option({buffer-name}, {option-name}, {value})
tree.custom_option({buffer-name}, {dict})
		Set {option-name} option to {value} in {buffer-name}
		buffer.
		If {buffer-name} is "_", the options are used for all buffers.
		If {dict} is available, the key is {option-name} and the value
		is {value}.
		Note: The all options are in |tree-options|.  However, "-" is
		substituted to "_", and "-" prefix is removed. >

	tree.custom_option('_', {
	    columns='mark:indent:icon:filename:type:size:time',
	})
<
							*tree.custom_source()*
tree.custom_source({source-name}, {var-name}, {value})
