1st code example on page |
the line of "===" signs
is mis-aligned. Remove all the thinspaces between "=". It should read
like the following (viewed in constant-width), with each header ("ID",
"Received", "From", "Subject") aligned with the start of a sequence of
"===..." below it:
format STDOUT_TOP =
ID Received From Subject
===== ========== ======================================== ====================
.
format STDOUT =
@<<<< @<<<<<<<<< @<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< @<<<<<<<<<<<<<<<<<<<
$_->id $_->received $_->from_address $_->subject

the figure was built for an old example, and is incorrect and confusing for the current example.
Update figure with the following text:
- In the first bubble, "/view/beer/1" changes to "/artist/edit/110".
- In the third bubble, "view" changes to "edit" and "beer" changes to "artist".
- In first bubble on the right, 'Load up row "1"' changes to 'Load up row "110"'.
- In the second bubble on the right, "BeerDB::Beer->view" changes to "CD::Artist->edit".

The subroutine defined at the bottom of the page should be named "error" instead of
"not_found" for consistency with the text and code in the "A POE Web Server" section

3rd Paragraph (in the code) |
The line of code:
if (SvTRUE(get_sv("MyModule::DEBUG", TRUE")) {...
clearly has too many quotes/is missing a quote around TRUE. Either
if (SvTRUE(get_sv("MyModule::DEBUG", "TRUE")) {...
or
if (SvTRUE(get_sv("MyModule::DEBUG", TRUE)) {...
worked fine for me (using ActivePerl on XP with VC++6 and similar-ish code: testing
whether a variable had been created already in the main package)
Note from the Author or Editor:
The quotes around TRUE should be removed and the line should read:
if (SvTRUE(get_sv("MyModule::DEBUG", TRUE)) {...
The reported version with "TRUE" will compile but give warnings - get_sv requires an integer, not a string, as second parameter. |
