| <p>So, you've got yourself a shiny new MacBook and you want to give PDL a spin. | ||
| Lucky you, because the OG author of PDL just got one recently and made an installer to save you a bunch of work. | ||
| It works pretty much for Monterey through to Sonoma, buuuuut ... of course my machine happens to be running <strong><em>Sequoia 15.1</em></strong>, | ||
| the latest release, which is not yet listed as having been tested but I believe in Santa and Santa believes in me!</p> | ||
|
|
||
| </section> | ||
| <section id="section-2"> | ||
| <p>I'm a <a href="https://brew.sh/">Homebrew</a> fan because it simplifies my life when installing third party software on the Mac. | ||
| Part of me wants to see what the minimum requirements are to get PDL up and running, but Life's Too Short.</p> | ||
|
|
||
| <p>Homebrew has formulae for <a href="https://metacpan.org/pod/PDL::Graphics::PLplot">PLPlot</a>, | ||
| <a href="https://metacpan.org/pod/PDL::Graphics::Gnuplot">Gnuplot</a>, GD for graphics, | ||
| the <a href="https://metacpan.org/pod/PDL::IO::HDF">HDF</a> library and <a href="https://metacpan.org/pod/PDL::GSL::CDF">Gnu Scientific Library</a> | ||
| as well as the X11 server needed for the <a href="https://pdl.perl.org/?page=demos/plot2D">PGPLOT demos</a>. | ||
| There's a bit of discussion about how <a href="https://www.xquartz.org/">XQuartz</a> is to be replaced by Apple's Metal, | ||
| but for now it looks best to stick with XQuartz. | ||
| Go for Maximum Install!</p> | ||
|
|
||
| <pre><code>brew install plplot gnuplot gd hdf5 gsl | ||
| brew install --cask xquartz | ||
| </code></pre> | ||
|
|
||
| <p>Now, does your MacBook have the Intel chip or the newer M1 chip found in post-2020 machines? | ||
| Figure that out and go to the <a href="https://github.com/PDLPorters/SciPDL/blob/main/README.md">Instructions</a>, | ||
| which consist of downloading the correct release, | ||
| open the <code>.dmg</code> file, drag and drop the image onto the Applications folder icon that's just popped up. | ||
| Done.</p> | ||
|
|
||
| <p>(yes, it is that easy)</p> | ||
|
|
||
| <p>If you rush to click on the <code>pdl></code> icon and get surprised by this error popup, | ||
| it means that you haven't read further down the <code>README</code> where it informs you not to panic, | ||
| <strong>Edit</strong> and <strong>Save</strong> the file (you won't see a Save button, but you just <strong>⌘ S</strong> or <strong>File > Save</strong>)</p> | ||
|
|
||
| <p><img alt="Not authorised message" src="apple_not_authorised.png" title="Error message"></p> | ||
|
|
||
| <p>For running the PGPLOT demo, you'll need to start the Xserver and if it says it can't connect, | ||
| try rebooting, starting the Xserver and entering the pdl shell. | ||
| If that still doesn't work, | ||
| open a terminal and follow the Running SciPDL instructions to set the environment and type <code>pdl</code> or <code>pdl2</code> at the prompt.</p> | ||
|
|
||
| <p>Parabolas are boring. Here's a cubic instead.</p> | ||
|
|
||
| <pre><code>pdl> use PGPLOT | ||
| pdl> use PDL::Graphics::PGPLOT | ||
|
|
||
| pdl> $ENV{PGPLOT_XW_WIDTH} = 0.3 | ||
| pdl> dev('/XSERVE') | ||
|
|
||
| pdl> $x = sequence(10) | ||
| pdl> $y = $x**3 - 8 * $x**2 + 20 | ||
|
|
||
| pdl> points $x, $y | ||
| </code></pre> | ||
|
|
||
| <p><img alt="Plotting a cubic with PGPLOT" src="cubic_pgplot.png" title="points along a cubic curve"></p> | ||
|
|
||
| <p>You'll have an excellent imagination to see the outline of Santa's pipe in the above plot, | ||
| no doubt inspired by a mince pie or two!</p> | ||
