file_temp: Create names for temporary files

Description

file_temp() returns the name which can be used as a temporary file.

Usage

file_temp(pattern = "file", tmp_dir = tempdir(), ext = "")
file_temp_push(path)
file_temp_pop()
path_temp(...)

Arguments

pattern

A character vector with the non-random portion of the name.

tmp_dir

The directory the file will be created in.

ext

The file extension of the temporary file.

path

A character vector of one or more paths.

...

Additional paths appended to the temporary directory by path().

Details

file_temp_push() can be used to supply deterministic entries in the temporary file stack. This can be useful for reproducibility in like example documentation and vignettes.

file_temp_pop() can be used to explicitly remove an entry from the internal stack, however generally this is done instead by calling file_temp().

path_temp() constructs a path within the session temporary directory.

Examples

# NOT RUN {
path_temp()
path_temp("does-not-exist")

file_temp()
file_temp(ext = "png")
file_temp("image", ext = "png")


# You can make the temp file paths deterministic
file_temp_push(letters)
file_temp()
file_temp()

# Or explicitly remove values
while (!is.null(file_temp_pop())) next
file_temp_pop()
# }
