SHOWG(1)

✨ NAME ✨

showg — bestie, it's literally the manual page for showg version 2.9.3 💖

---

🦋 SYNOPSIS 🦋

showg [-p#:#l#o#Ftq] [-a|-A|-c|-d|-e] [infile [outfile]]

---

🌸 DESCRIPTION 🌸

Okay so what does showg do? It writes graphs in human-readable format. That's the whole vibe. 👑

infile is the input file, and it's gotta be in graph6, sparse6 or digraph6 format, no cap.

🚨 real talk: this program does not support incremental sparse6 files. Not even a little. If that's what you need, go use listg instead, bestie.

outfile is the output file. And if you don't say anything? The defaults are standard input and standard output. Chill, it's got you. 🫶

🎀 the options, one by one 🎀

• -p#, -p#:#, -p#-# — only display one graph, or a whole sequence of graphs. The first graph is number 1, obviously (we count from one here, iconic behaviour). A second number that's empty or zero means infinity ♾️
• -a — write the adjacency matrix ✨
• -A — same as -a, but with a space between entries. Personal space matters 💅
• -d — write output to satisfy dreadnaut 🐉
• -c — write compact dreadnaut form with minimal line-breaks, she's efficient
• -e — write a list of edges, preceded by the order and the number of edges 🔗
• -o# — specify number of first vertex (default is 0)
• -t — write upper triangle only. Heads up: this affects -a, -A, -d and the default. 🔺
• -F — write a form-feed after each graph except the last one 📄
• -l# — specify screen width limit (default 78, 0 means no limit). ⚠️ Ngl, this is not currently implemented with -a or -A, so don't come for me.
• -q — suppress auxiliary output 🤫

💀 -a, -A, -c, -d and -e are incompatible. Pick one. They cannot coexist. It's giving "choose your fighter."

that's the whole page, bestie — go forth and graph 🌈
