LISTG(1)

✨ LISTG(1) ✨

okay so bestie, this is the manual page for listg, and the version we're vibing with is 2.9.3. it writes graphs in a format actual humans can read. that's the whole gig. let's get into it 💅

📜 SYNOPSIS 📜

listg [-fp#:#l#o#Ftq] [-a|-A|-c|-d|-e|-H|-M|-W|-L|S|-s|-b|-G|-y|-Yxxx]

yes the flags look like a keyboard smash. no, we are not skipping any of them. stay with me. 🫶

💖 DESCRIPTION 💖

[infile [outfile]]

Write graphs in human-readable format.

that's it, that's the mission statement. you hand it graphs, it hands them back looking like something a person can actually read, and infile / outfile are the optional in and out slots. 🌸

🎀 the flags 🎀

🌈 input + selection vibes 🌈

• -f — assume the inputs all have the same size. heads up: this one is only used when the input comes from a file, and only if -p is also given.
• -p#, -p#:#, -p#-# — only display one graph, or a whole sequence of graphs. the first graph is number 1. if there's a second number and it's empty or zero, that means infinity. lowkey important: this option won't work for incremental input.

🖼️ output format picks 🖼️

• -a — write it as an adjacency matrix instead of a list of adjacencies.
• -A — same as -a, but with a space between entries.
• -d — write the output so it satisfies dreadnaut.
• -c — write ascii form with minimal line-breaks.
• -e — write a list of edges, preceded by the order and the number of edges.
• -M — write in Magma format.
• -m — write in Mathematica format.
• -W — write the matrix in Maple format.
• -H — write in HCP operations research format.
• -T — write in the edge-list format that the program tutte needs.
• -b — write in DIMACS format.
• -G — write in GRAPE format.
• -y — write in dot file format.
• -Yxxx — extra dotty commands for dot files (the argument keeps going to the end of the param).
• -t — write the upper triangle only (this one affects -a, -A, -d and the default).
• -s — write only the numbers of vertices and edges.

🧮 matrix modifiers 🧮

• -L — (only with -M or -W) write the Laplacian instead of the adjacency matrix.
• -S — (only with -M or -W) write the signless Laplacian, not the adjacency matrix.

🔧 layout + housekeeping 🔧

• -l# — set the screen width limit (default is 78, and 0 means no limit). ngl, heads up: this is not currently implemented with -a or -A.
• -o# — set the number of the first vertex (the default is 0).
• -F — write a form-feed after each graph except the last one.
• -q — suppress auxiliary output. the quiet luxury option. 🙈

⚠️ the incompatible era, fr fr: -a, -A, -c, -d, -M, -W, -H and -e are incompatible. pick a lane bestie, don't mix them. 💀

and that's the whole page, you ate it, no crumbs. 💖

this was listg version 2.9.3, dated September 2026 — periodt, go make some graphs look pretty 🦋✨👑
