FoldableTreeNodeImpl

FoldableTreeNodeImpl#

class penzai.treescope.foldable_representation.foldable_impl.FoldableTreeNodeImpl[source]#

Concrete implementation of a node that can be expanded or collapsed.

This is kept separate from the abstract definition of a FoldableTreeNode to avoid strong dependencies on its implementation as much as possible.

Variables:

contents (RenderableTreePart) – Contents of the foldable node.
label (RenderableTreePart) – Optional label for the foldable node. This appears in front of the contents, and clicking it expands or collapses the foldable node. This should not contain any other foldables and should generally be a single line.
expand_state (ExpandState) – Current expand state for the node.

Inherited Attributes

`collapsed_width`	The length of this rendering if collapsed in one line, in characters.
`newlines_in_expanded_parent`	The number of newlines in this rendering if in an expanded parent.
`tags_in_this_part`	Returns a set of "tag" objects contained in this part.

Methods

`__init__`(contents[, label, expand_state])
`as_expanded_part`()	Returns the contents of this foldable when expanded.
`get_expand_state`()	Returns the node's expand state.
`html_setup_parts`(setup_context)
`render_to_html`(stream, *[, at_beginning_of_line])
`render_to_text`(stream, *, expanded_parent, ...)
`set_expand_state`(expand_state)	Sets the node's expand state.

`label`
`newlines_in_expanded_parent`	The number of newlines in this rendering if in an expanded parent.

foldables_in_this_part()

Returns this node itself, since it is a foldable node.

as_expanded_part() → RenderableTreePart[source]#: Returns the contents of this foldable when expanded.

set_expand_state(expand_state: ExpandState)[source]#: Sets the node’s expand state.
