==name rez

==short-description

Reads text out of resource files.

==argument string resource-identifier

The identifier of the resource to display, of the form C<R:FILENAME:ID[:OFFSET]>.

==option bool x hex

Display the resource in hex.

==long-description

Extracts a string from a resource file, taking in to account the current device language settings and the different drives that a resource file might be installed on to.

The C<resource-identifier> syntax is as follows:

=over 4

=item *

C<FILENAME> is the path of the resource file, relative to the resource directory and not including extension. Eg "Apps\MyApp" would match a file that (on an unlocalised, uncustomised system) resided at C<Z:\Resource\Apps\MyApp.rsc>.

=item *

C<ID> is the numeric resource id, in hex with preceding 0x or in decimal.

=item *

C<OFFSET> is a sequence of numbers and d/D characters. A number indicates the number of bytes to skip over, 'D' means read a 16-bit descriptor (an LTEXT, in resource file parlance), 'd' means read an 8-bit descriptor (LTEXT8). So an offset of 14DD24D means 'skip 14 bytes from the start of the resource, then skip over 2 LTEXTs, then skip another 24 bytes, the descriptor I want is next (and is a 16-bit LTEXT).

If no offset is specified, the whole resource is read as if it was a TBUF. This is different to specifying an offset of 0D, which would be a resource starting with an LTEXT (the difference is whether there's a leading length byte - TBUF doesn't use one).

=back

A full resource identifier might be C<R:Apps\MyApp:0x23> indicating resource 0x23 of C<x:\Resource\Apps\MyApp.rxx>. Or C<R:eikcoctl:7:8D30d> indicating resource 7 of C<x:\Resource\eikcoctl.rxx>, seeking 8 bytes, one 16-bit descriptor, 30 bytes more, then the result is a 8-bit descriptor at that point.
