Decode webR REPL link(s) to extract files to local directory

decode_webr_link.Rd

Decodes webR REPL sharelinks to extract the embedded files and save them to a local directory. This is the reverse operation of creating webR links. Handles both single URLs and multiple URLs automatically.

Usage

decode_webr_link(
  url,
  output_dir = "./webr_files",
  overwrite = FALSE,
  create_subdir = TRUE,
  name_dirs = TRUE
)

Arguments

url

Character string or vector containing webR REPL URL(s)

output_dir

Character string specifying the output directory path (default: "./webr_files")

overwrite

Logical. Whether to overwrite existing files (default: FALSE)

create_subdir

Logical. Whether to create subdirectories. For single URLs, creates a subdirectory named after the URL hash. For multiple URLs, creates numbered subdirectories (default: TRUE)

name_dirs

Logical. For multiple URLs only: whether to name directories by URL index rather than hash (default: TRUE). Ignored for single URLs.

Value

For single URL: webr_decoded object. For multiple URLs: webr_decoded_batch object.

Examples

if (FALSE) { # \dontrun{
# Single URL
url <- "https://webr.r-wasm.org/latest/#code=eJy1..."
result <- decode_webr_link(url)
print(result)

# Multiple URLs
urls <- c(
  "https://webr.r-wasm.org/latest/#code=...",
  "https://webr.r-wasm.org/v0.5.4/#code=..."
)
results <- decode_webr_link(urls)
print(results)

# Custom settings for single URL
result <- decode_webr_link(url,
                          output_dir = "./my_code",
                          create_subdir = FALSE,
                          overwrite = TRUE)

# Custom settings for multiple URLs
results <- decode_webr_link(urls,
                           output_dir = "./my_scripts",
                           name_dirs = FALSE)  # Use hash-based names
} # }
