💅 NAME 💅

gbase — the lil icon that sets the base value of a source graph ✨

Fr fr, this is the glow-up tool for your graphs' index vibes. This page is from the Scotch user's manual, bestie, and it's about to be your new fave 🫶

🎀 SYNOPSIS 🎀

gbase [options] bval [igfile] [ogfile]

That's the whole vibe check: options, a base value, an input, an output. Easy 💅

✨ DESCRIPTION ✨

Okay so bestie, here's the tea ☕ — the gbase program lets you set to bval the base value of a source graph. And what even is a base value, you ask? It's the starting index used to number its vertices and edges. Like, do your vertices start at 0 or at 1? That's the whole question. That's it. That's the base value.

The base value can be set to 0 or 1 — those are the only two options, no in-between, no base value of 7, sorry babe 🙈 — so that graphs can be easily imported from and/or exported to tools written in C or Fortran. The C girlies and the Fortran girlies need different numbers and gbase is the translator at the function, keeping the peace 🕊️

Scotch can handle graphs irrespective of their base value, ngl that's the most unbothered, well-adjusted behaviour and we love that for it. 💚

🗜️ Compression, because of course 🗜️

When the proper libraries have been included at compile time, gbase can directly handle compressed graphs, both as input and output. Iconic. 🙌

A stream is treated as compressed whenever its name is postfixed with a compressed file extension — as in 'brol.grf.bz2' or '-.gz' 👀

The compression formats which can be supported are:

  • the bzip2 format ('.bz2')
  • the gzip format ('.gz')
  • the lzma format ('.lzma')

So yes, it sniffs the suffix and just knows. Main character energy, honestly 👑

🌈 OPTIONS 🌈

  • -h — Display some help. A lil "here's what's up" when you need it 🫶
  • -V — Display program version and copyright. The receipts, the credentials, the whole origin story 💖

🍓 EXAMPLE 🍓

Set the base of graph 'brol.grf' to 1, and write the modified graph to file 'brol_b1.grf':

$ gbase 1 brol.grf brol_b1.grf

Look at her go 😭✨ one line, zero drama, base value handled.

💀 bestie reminder: the base value is only 0 or 1. Don't come at it with a 2 and expect slay. It won't.

k bye, love u, go fix ur indices 🎀🦋🌸
