💖 Ace::Graphics::Glyph::arrow — the "arrow" glyph 💖

📛 NAME

Ace::Graphics::Glyph::arrow — The "arrow" glyph 💅

---

👀 SYNOPSIS

See L<Ace::Graphics::Panel> and L<Ace::Graphics::Glyph>.

(yeah she's minimal, she lets the other docs do the talking 🙈)

---

🌸 DESCRIPTION

So this glyph draws arrows. and the way that it's customizable?? obsessed. depending on your options, the arrows can be:

• labeled 🏷️
• oriented vertically or horizontally (your choice bestie)
• or they can carry major and minor ticks so you can literally use them as a scale 📏

it's giving "one glyph, so many jobs." main character energy fr fr. 👑

✨ OPTIONS ✨

so on top of all the common options (iykyk), the following glyph-specific options are recognized:

• -tick — whether to draw major and minor ticks. the values are: 0 = no ticks, 1 = major ticks, 2 = minor ticks. default is 0 🎚️
• -parallel — whether to draw the arrow parallel to the sequence or perpendicular to it. default is true 📐
• -northeast — whether to draw the north or east arrowhead (depends on the orientation, bestie). default is true 🌬️
• -southwest — whether to draw the south or west arrowhead (again, depends on orientation). default is true 🌊

---

ok so here's the part that ate: set -parallel to false and you get to display a point-like feature — like a polymorphism, or just to indicate an important location. very "mark your spot" of it.

and if the feature start == end, then the glyph will draw a single arrow right at the designated location:

       ^
       |

but OTHERWISE (start ≠ end, obviously) you get two arrows — one at the start, one at the end:

       ^              ^
       |              |

periodt. two arrows, zero confusion. 🫶
