    By now you've all seen The St. Larry Wall Shrine. Well, it could use a fresh coat of gold leaf and shellac. Therefore, we are soliciting Larry-related items to be placed on the shrine. Links to offsite content are good; or if you have small bits of content, such as quotes, you'd like to contribute, that's fine too. Please reply to this Quest with your humble offerings. Thank you! And may St. Larry bless your codings and your debuggings.

    Esteemed Monk kcott has recently proposed an excellent idea.

    heretoforthwithstanding, we invite all monks to submit ideas for new monk quips!

    Your quip suggestion should include the following details:

    • Intended quip location: either XP Nodelet, Chatterbox, or Monkbar (that's the page header).
    • Text of quip.
    • Optional: background & foreground colours. If you include these, be sure they are nicely contrasting.

The Perl and Raku Conference: Call for Speakers Renewed
on Apr 10, 2024 at 23:06
1 reply by talexb

    The Perl and Raku Conference is fast approaching! We will be in Las Vegas on June 24-28, (main conference June 25-27). We want more speakers, so we are reopening the full call for talks/papers/posters.

    The new deadline is April 20, midnight Las Vegas time. (April 21 00:00 UTC) (April 21 07:00 UTC)

    Now that the eclipse is not a distraction, please consider submitting a talk (50 minute, or 20 minute) or a scientific paper or poster before that deadline! Link to conference website Speakers will be informed of talk acceptance by April 30. Whether speaker or attendee, we look forward to seeing you in Las Vegas!

    Nota Bene: 20m talks, 50m talks, papers, and posters earn free admission for the presenter. Giving a Lightning Talk does not reduce the admission fee, but earns our appreciation and delight!

    Update on 2024-0418: Jeepers. Kids, don't play with time zones. There are so many ways to get them wrong. Thanks to LanX.

    Thanks PJ. We owe you so much. Groklaw -- RIP -- 2003 to 2013.

    Hi Monks,

    i am not able to follow symbolic links when using the find() command. it says on the manual that the 'follow' or 'follow_fast' option should be used but i don't understand how to use it together with the '\&wanted' routine -

    use File::Find; find(\&wanted, @directories); find(\%options, @directories);
    thanks a lot, Yaron.
Imager font problem

    Dear Monks,

    I'm using Imager to render truetype fonts but there is no output, and no error, it's just blank. I checked $Imager::formats{tt} to see if Imager has truetype support and it's blank. I have some /usr/share/fonts/truetype so I dunno why Imager says that. How can Imager be compiled with tt support?

    I have another computer with a similar setup but on that one Imager does render truetype even though $Imager::formats{tt} is blank! They are different operating systems and versions of Imager so I don't know. I could install the only fonts that Imager supports on this box: Freetype2, but I want to use truetype and would appreciate any ideas you have on how to get Imager to use my fonts.

    Thank you.

    My script below works, but i have one problem, it just display out 1 record

    What i need is to return all records from database

    my $sth = $dbh->prepare("SELECT snd.name, snd.country, m.item, m.eqty, m.price, m.line, m.prodct FRO +M buys as m JOIN Busers as snd ON snd.id = m.buyer WHERE CASE WHEN (SELECT SUM(s +tatus = ?) FROM buys) > 0 THEN m.status = ? ELSE m.status = ? OR m. +status = ? OR m.status = ? END ORDER BY created ASC"); $sth->execute('sold', 'forsell', 'bugt', 'paid', 'inshop'); my $Data = $sth->fetchall_arrayref(); foreach my $Data (@$Data) { my ($name, $country, $item, $eqty, $price, $line, $prodct) = @$Dat +a; $html = "<tr> <td> <p>$name</p> <p> $eqty, $price, $line, </p> $prodct $country </td> </tr> "; }
External (extra) files when using Inline::CPP

    First of all, i have to admit that i feel that i should know this already, but i just don't.

    Is it possible to add external cpp/h files when using Inline::CPP? I only need XS bindings for the stuff i'm inlining, the rest only needs to be accesible through the inlined CPP code.

    Here is the simplest example i could tink of.

    test.pl
    use Inline CPP; for(1..3) { print "Perfect random number: ", cast_die(), "\n"; } __END__ __CPP__ #include "xkcd.h" int cast_die() { int rolled = xkcd_dice_roll(); return rolled; }
    xkcd.h
    #ifndef XKCD_DICE #define XKCD_DICE // See https://xkcd.com/221/ for why this is absolutely perfect #define FAIRLY_GENERATED_RANDOM_NUMBER 4 int xkcd_dice_roll(); #endif
    xkcd.cpp
    #include "xkcd.h" int xkcd_dice_roll() { return FAIRLY_GENERATED_RANDOM_NUMBER; }

    Is something like this even possible with Inline::CPP?

Running modulino inside BEGIN

    Hi

    while developing a module I like to run (F5) the testsuite automatically. I'm using a moulino approach which works considerably well

    #BEGIN { # TODO unless ( caller() ) { # Modulino for development exec q(cd ../..; prove ./t/); #run proove from dist root } #}

    It occurred to me that I have to enclose this inside a BEGIN block to avoid the overhead and side-effects of loding all modules with use (this happens in the BEGIN phase) before the unless is executed at run time.

    This doesn't work, since caller() IS defined inside BEGIN

    BEGIN { warn "Caller Begin: ",defined caller(0) } warn "Caller Normal: ",defined caller();

    Caller Begin: 1 at /home/lanx/... Caller Normal: at /home/lanx/...

    EDIT Solution

    while writing this I realized that BEGIN is called 2 levels down, hence caller(2) seems to work

    BEGIN { # TODO unless ( caller(2) ) { # Modulino for development exec q(cd ../..; prove ./t/); #run proove from dist root } }

    Is this reliable?

    (I think it is, but I already wrote this post, before finding the solution and the monastery is not overwhelmed with writeups :)

CPAN test suites with SQL

    Hi

    I'm developing a DBIx distribution and need to check plenty of SQL in the tests.

    My approach is to use SQLite as primary engine, since it comes with the DBD::SQLite module installed and that's not much of a prerequisite (it's even comes bundled with Strawberry Perl!)

    My issue is where to put the temporary SQLite file...

    • in the distribution's /t directory?
    • in the FS's /tmp ? What about other OSes?
    • or should I restrict the SQL-testing to the authors system

    Those SQLite files don't become big, but I'm not sure about writing stuff into the dist directory. On a side note:

    I want to be able to switch to other DB-Servers while testing. (But now really author's side unless explicitly wanted by the user)

    What's the best approach to make this configurable?

    • A prove option
    • an ENV setting
    • a prompt while testing? (DBI can test for available DBD:: drivers)

    Cheers Rolf
