R: Create names for temporary files

file_temp {fs} | R Documentation

## 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

    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()
