Replace selected elements with a new element in a tree-sitter tree

Replace all selected elements with a new element.

Usage

ts_tree_update(tree, new, options, ...)

Arguments

tree

A ts_tree object.

new

The new element to replace the selected elements with.

The type of new depends on the parser and the method that implements the insertion. See details in the manual of the specific parser.

options

A list of options for the update.

See details in the manual of the specific parser.

...

Extra arguments for methods.

Value

The modified ts_tree object with the selected elements replaced by the new element.

Details

If the tree does not have a selection, the new element replaces the whole document.

JSONC

 

tree <- tsjsonc::ts_parse_jsonc("{ \"a\": true, \"b\": [1, 2, 3] }")
tree |> ts_tree_update(as.list(4:6))

#> # jsonc (5 lines)
#> 1 | [
#> 2 |   4,
#> 3 |   5,
#> 4 |   6
#> 5 | ]

If the tree has an empty selection, the new element is inserted at the position of where the selected elements would be.

JSONC TOML

 

tree <- tsjsonc::ts_parse_jsonc("{ \"a\": true, \"b\": [1, 2, 3] }")
tree |> ts_tree_select("new") |> ts_tree_update(as.list(4:6))

#> # jsonc (13 lines)
#>  1 | {
#>  2 |     "a": true,
#>  3 |     "b": [
#>  4 |         1,
#>  5 |         2,
#>  6 |         3
#>  7 |     ],
#>  8 |     "new": [
#>  9 |         4,
#> 10 |         5,
#> ℹ 3 more lines
#> ℹ Use `print(n = ...)` to see more lines

 

tree <- tstoml::ts_parse_toml("a = true\nb = [1, 2, 3]")
tree |> ts_tree_select("new") |> ts_tree_update(as.list(4:6))

#> # toml (3 lines)
#> 1 | a = true
#> 2 | b = [1, 2, 3]
#> 3 | new = [ 4, 5, 6 ]
