(chibi temp-file)

(call-with-temp-file template proc [mode])

Runs a procedure on a temporary file. proc should be a procedure of three values: (path out preserve), where path is the path to the temporary file, out is an output port opened on the file, and preserve is a thunk to disable deleting the file. The file name will be in a temp directory, based on template and having the same extension if present, with permissions from the optional mode which defaults to #o700. Returns the result of proc, after first deleting the file if the preserve thunk was not called.

(call-with-temp-dir template proc [mode])

Runs a procedure on a temporary directory. proc should be a procedure of two values: (path preserve), where path is the path to the temporary directory and preserve is a thunk to disable deleting the dir. The directory name will be in a temp directory, based on template, with permissions from the optional mode which defaults to #o700. Returns the result of proc, after first deleting the file hierarchy rooted at path if the preserve thunk was not called.
