💖 Relational — bestie edition 💖

okay so this is the manual for Relational(1), from the General Commands Manual section of your local man tree, and honestly? she's a whole vibe. it's the relational-cli situation. let's get into it 🦋

✨ NAME ✨

relational-cli — an implementation of Relational algebra. no cap, that's literally the whole thing 💅

🎀 SYNOPSIS 🎀

relational-cli [OPTIONS] [ FILE ...]

🌸 DESCRIPTION 🌸

ok so picture this: this program gives you a command line interface for running relational algebra queries. that's its whole job and it's iconic for it. it's meant for experimenting with relational algebra queries — like a lil playground, a sandbox, a science fair project but make it math 🧚

📜 SCRIPTING 📜

the tea is: this tool always runs in interactive mode. always. she does not know how to be anything else. but — and this is the slay part — you can still write a whole sequence of queries into a script and run it that way:

relational-cli < script.txt

and here's the little ruleset, bestie, write it down 📝:

  • the result of all the lines that do not terminate with a ; are printed.
  • comments are lines beginning with ;.
  • whenever stdin or stdout are not a terminal, silent mode will be used, which prints less debug information, to avoid cluttering.
lowkey silent mode is the "we're in public, act normal" of this program 😭

💅 OPTIONS 💅

a summary of options is included below. they're short, they're sweet, they're all lowercase:

  • -v — show version information and exit. bye bestie 👋
  • -h — shows help and exit.
  • -q — uses the Qt5 GUI. fancy!! windowed!! ✨
  • -r — uses the readline UI (this is the default, in case you were wondering 👑).
