Tree-sitter AST classes

S7 classes representing the tree-sitter (tree-sitter-qmd) AST produced by pampa for a QMD document. Unlike the Pandoc AST, tree-sitter node kinds are open-ended grammar-defined strings, so a single ts_node class with a kind string property is used.

Usage

ts_point(row = NA_integer_, column = NA_integer_)

ts_range(
  start_byte = NA_integer_,
  end_byte = NA_integer_,
  start_point = ts_point(),
  end_point = ts_point()
)

ts_nodes(content = list())

ts_node(
  kind = "",
  is_named = TRUE,
  field_name = NULL,
  range = ts_range(),
  text = NULL,
  children = ts_nodes(list())
)

ts_tree(root = ts_node(), language = "qmd", diagnostics = list())

Arguments

row, column

For ts_point, the 0-based row and column.

start_byte, end_byte

For ts_range, the byte offsets of the span.

start_point, end_point

For ts_range, the start/end ts_points.

content

For ts_nodes, a list of ts_nodes.

kind

For ts_node, the grammar node kind (a string).

is_named

For ts_node, whether the node is named (vs anonymous).

field_name

For ts_node, the parent field name, or NULL.

range

For ts_node, its ts_range.

text

For ts_node, the source text it carries, or NULL.

children

For ts_node, its child ts_nodes.

root

For ts_tree, the root ts_node.

language

For ts_tree, the grammar name (default "qmd").

diagnostics

For ts_tree, a list of pampa_diagnostics.
