Experimental bindings to a WebAssembly port of the toml_edit Rust crate.
Allows for modifying TOML data while preserving order, comments and whitespace.
Installation requires no compilation:
pak::pak("jeroen/tomleditjs")
The edit_toml function simply takes a TOML string and returns the modified TOML string:
# Read some TOML dadta
toml <- readLines('https://raw.githubusercontent.com/posit-dev/air/refs/heads/main/Cargo.toml')
# Modify some fields
toml <- edit_toml(toml, 'workspace.package.rust-version', '1.84')
toml <- edit_toml(toml, 'workspace.dependencies.bla', list(path = "./yolo", rev = "123"))
print(toml)You can also parse the toml into an R list:
parse_toml(toml)
