Data::Section::Simple is a simple module to extract data from
__DATA__
section of the file.
As the name suggests, this module is a simpler version of the excellent Data::Section. If you want more functionalities such as merging data sections or changing header patterns, use Data::Section instead.
This module does not implement caching (yet) which means in every
get_data_section
or get_data_section($name)
this module
seeks and re-reads the data section. If you want to avoid doing so for
the better performance, you should implement caching in your own
caller code.
If you data section has literal __DATA__
in the data section, this
module might be tricked by that. Although since its pattern match is
greedy, __DATA__
appearing before the actual data section
(i.e. in the code) might be okay.
This is by design -- in theory you can tell
the DATA handle before
reading it, but then reloading the data section of the file (handy for
developing inline templates with PSGI web applications) would fail
because the pos would be changed.
If you don't like this design, again, use the superior Data::Section.
If you enable utf8 pragma in the caller's package (or the package
you're inspecting with the OO interface), the data retrieved via
get_data_section
is decoded, but otherwise undecoded. There's no
reliable way for this module to programmatically know whether utf8
pragma is enabled or not: it's your responsibility to handle them
correctly.
