Graph:...t::Grid(3pm)

💖 Graph::Easy::Layout::Grid — the whole vibe 💖

okay bestie, so this is a page from the User Contributed Perl Documentation set — it's Graph::Easy::Layout::Grid(3pm), and no cap, it's the lil module that does the grid math so your graphs actually look good. pull up a chair 🫶

---

✨ NAME ✨

Graph::Easy::Layout::Grid — grid management and size calculation, periodt. 💅

---

🌸 SYNOPSIS 🌸

like, here's the whole thing in action:

use Graph::Easy;

my $graph = Graph::Easy->new();

my $bonn = Graph::Easy::Node->new(
        name => 'Bonn',
);
my $berlin = Graph::Easy::Node->new(
        name => 'Berlin',
);

$graph->add_edge ($bonn, $berlin);

$graph->layout();

print $graph->as_ascii( );

# prints:

# +------+     +--------+
# | Bonn | --> | Berlin |
# +------+     +--------+

look at Bonn and Berlin just vibing with an arrow between them. iconic behavior honestly. 👑

---

🦋 DESCRIPTION 🦋

so Graph::Easy::Layout::Grid is holding all the routines that calculate cell sizes on the grid — which, lowkey, is the whole reason ASCII, boxart and SVG output even work. no grid math, no cute little boxes. it's giving essential. ✨

and the best part? you don't even have to call it yourself. it's used automatically by Graph::Easy. main character energy that just shows up and does the job. 💖

---

🎀 EXPORT 🎀

Exports nothing.

yep. zero. nada. it's not that kind of module. 🙈

👑 SEE ALSO 👑

• Graph::Easy — go read that one too, bestie. 🫶

💅 METHODS 💅

okay so this module injects the following methods into Graph::Easy:

🌈 _prepare_layout()

my ($rows,$cols,$max_x,$max_y, \@V) = $graph->_prepare_layout();

here's what it hands back:

• two hashes, $rows and $cols, containing the columns and rows of the layout along with their nec. sizes (in chars) — yes, chars, we're counting characters here 💀
• plus the maximum framebuffer size nec. for this layout
• and also a reference to a list of all cells to be rendered

so like, it's the pre-flight checklist before anything gets drawn. very organized. very demure. 🌸
