Text::Template::Inline - Easy formatting of hierarchical data


 # you can import any name you want instead of "render"
 use Text::Template::Inline 'render';

 # yields "Replace things and stuff."
 render {
    foo => 'things',
    bar => 'stuff',
 }, q<Replace {foo} and {bar}.>;

 # yields "Three Two One Zero"
 render [qw/ Zero One Two Three /], '{3} {2} {1} {0}';

 # for a blessed $obj that has id and name accessors:
 render $obj, '{id} {name}';

 # a "fat comma" can be used as syntactic sugar:
 render $obj => '{id} {name}';

 # it's also possible to traverse heirarchies of data,
 # even of different types.
 # the following yields "one two three"
 render {
    a => { d => 'one' },
    b => { e => 'two' },
    c => { f => [qw/ zero one two three /], },
 } => '{a.d} {b.e} {c.f.3}';

 # there's also an automatic unindent feature that
 # lines up to the least-indented line in the template:
 render {
    a => { d => 'one' },
    b => { e => 'two' },
    c => { f => [qw/ zero one two three /], },
 } => q{
 # the above results in this:


This module exports a fuction render that substitutes identifiers of the form {key} with corresponding values from a hashref, listref or blessed object. It has features that work well with inline documents like heredocs, such as automatic unindent.

The implementation is very small and simple. The small amount of code is easy to review, and the resource cost of using this module is minimal.


There is only one function defined by this module. It is exported automatically.

render ( $data, $template )

Each occurrence in $template of the form {key} will be substituted with the corresponding value from $data. If there is no such value, no substitution will be performed.

First $template is intelligently unindented and leading or trailing newlines are trimmed.

If $data is a blessed object, the keys in $template correspond to accessor methods. These methods should return a scalar when called without any arguments (other than the reciever).

if $data is a hash reference, the keys in $template correspond to the keys of that hash. Keys that contain non-word characters are not replaced.

if $data is a list reference, the keys in $template correspond to the indices of that list. Keys that contain non-digit characters are not replaced.

The modified $template string is then returned.
