Padre::Task::Eval(3pm) User Contributed Perl Documentation Padre::Task::Eval(3pm)NAME
Padre::Task::Eval - Task for executing arbitrary code via a string eval
SYNOPSIS
my $task = Padre::Task::Eval->new(
prepare => '1 + 1',
run => 'my $foo = sub { 2 + 3 }; $foo->();',
finish => '$_[0]->{prepare}',
);
$task->prepare;
$task->run;
$task->finish;
DESCRIPTION
Padre::Task::Eval is a stub class used to implement testing and other miscellaneous functionality.
It takes three named string parameters matching each of the three execution phases. When each phase of the task is run, the string will be
eval'ed and the result will be stored in the same has key as the source string.
If the key does not exist at all, nothing will be executed for that phase.
Regardless of the execution result (or the non-execution of the phase) each phase will always return true. However, if the string eval
throws an exception it will escape the task object (although when run properly inside of a task handle it should be caught by the handle).
METHODS
This class contains now additional methods beyond the defaults provided by the Padre::Task API.

Padre::Task::LexicalReplaceVariable(3pm) User Contributed Perl Documentation Padre::Task::LexicalReplaceVariable(3pm)NAME
Padre::Task::LexicalReplaceVariable - Lexically variable replace using PPI
SYNOPSIS
my $replacer = Padre::Task::LexicalReplaceVariable->new(
document => $document_obj,
location => [ $line, $column ], # the position of *any* occurrence of the variable
replacement => '$foo',
);
$replacer->schedule;
DESCRIPTION
Given a location in the document (line/column), determines the name of the variable at this position, finds where the variable was defined,
and lexically replaces all occurrences with another variable.
The replacement can either be provided explicitly by the user (using the "replacement" option) or the user may set the "to_camel_case" or
"from_camel_case" options. In that case the variable will be converted to/from camel case. With the latter options, "ucfirst" will force
the upper-casing of the first letter (as is typical with global variables).
SEE ALSO
This class inherits from "Padre::Task::PPI".
