VERSION

version 0.21

SYNOPSIS

    my $munged = PPIx::EditorTools::RenameVariable->new->rename(
        code        => $code,
        line        => 15,
        column      => 13,
        replacement => 'stuff',
    );
    my $code_as_strig = $munged->code;
    my $code_as_ppi   = $munged->ppi;
    my $location      = $munged->element->location;

DESCRIPTION

This module will lexically replace a variable name.

METHODS

new()

Constructor. Generally shouldn't be called with any arguments.

rename( ppi => PPI::Document $ppi, line => Int, column => Int, replacement => Str )
rename( code => Str $code, line => Int, column => Int, replacement => Str )
rename( code => Str $code, line => Int, column => Int, to_camel_case => Bool, [ucfirst => Bool] )
rename( code => Str $code, line => Int, column => Int, from_camel_case => Bool, [ucfirst => Bool] )

Accepts either a PPI::Document to process or a string containing the code (which will be converted into a PPI::Document) to process. Renames the variable found at line, column with that supplied in the replacement parameter and returns a PPIx::EditorTools::ReturnObject with the new code available via the ppi or code accessors, as a PPI::Document or string, respectively. The PPI::Token found at line, column is available via the element accessor.

Instead of specifying an explicit replacement variable name, you may choose to use the to_camel_case or from_camel_case options that automatically convert to/from camelCase. In that mode, the ucfirst option will force uppercasing of the first letter.

You can not specify a replacement name and use the to/from_camel_case options.

Croaks with a "no token" exception if no token is found at the location. Croaks with a "no declaration" exception if unable to find the declaration.
