(scheme file) - R7RS File Library

File input/output operations for opening, reading, and writing files.

For extended filesystem operations (directories, globs, metadata), use (sigil fs) instead.

Exports

call-with-input-fileprocedure

Call a procedure with an input port, ensuring cleanup.

Opens the file, passes the port to proc, closes the port, and returns proc's result. The port is closed even if proc raises an error.

(call-with-input-file "data.txt"
  (lambda (port)
    (read-line port)))

Re-exported from (sigil io)

call-with-output-fileprocedure

Opens the file, passes the port to proc, closes the port, and returns proc's result.

  (lambda (port)
    (write-string "Hello!" port)))
