NAME

6       Test::Trap::Builder::TempFile - Capture strategies using File::Temp
7

VERSION

9       Version 0.3.4
10

DESCRIPTION

12       This module by default provides a capture strategy based on File::Temp
13       for the trap's output layers.
14
15       The import accepts a name (as a string; default tempfile) and options
16       (as a hashref; by default empty), and registers a capture strategy with
17       that name and a variant implementation based on the options.
18
19       Note that you may specify different strategies for each output layer on
20       the trap.
21
22       See also Test::Trap (:stdout and :stderr) and Test::Trap::Builder
23       (output_layer).
24

OPTIONS

26       The following options are recognized:
27
28   preserve_io_layers
29       A boolean, indicating whether to apply to the handles writing to and
30       reading from the tempfile, the same perlio layers as are found on the
31       to-be-trapped output handle.
32
33   io_layers
34       A colon-separated string representing perlio layers to be applied to
35       the handles writing to and reading from the tempfile.
36
37       If the preserve_io_layers option is set, these perlio layers will be
38       applied on top of the original (preserved) perlio layers.
39

CAVEATS

41       Using File::Temp, we need privileges to create tempfiles.
42
43       We need disk space for the output of every trap (it should clean up
44       after the trap is sprung).
45
46       Disk access may be slow -- certainly compared to the in-memory files of
47       PerlIO.
48
49       If the options specify (explicitly or via preserve on handles with)
50       perlio custom layers, they may (or may not) fail to apply to the
51       tempfile read and write handles.
52
53       Threads?  No idea.  It might even work correctly.
