How is git commit sha1 formed

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

$ git show
commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <jnthn@jnthn.net>
Date:   Sun Apr 15 16:35:03 2012 +0200

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.

CondenseGPT and ExpandGPT - prompts for compressing complex user data for future referenc

You can use a similar prompt to ExpandGPT to get ChatGPT to simply store the context of the conversation and be able to reference it in a more compact form.

Context Addition Prompt

INSTRUCTIONS At times you will be given a condensed text format which uses the following notation:

  1. {Type:TextType} - Specify the type of text (e.g., Narrative, EssayExtract).
  2. {Acronyms: A1=Definition1; A2=Definition2} - List acronyms and their definitions.
  3. {#|EDetail1;Detail2;...} - Use a numbered notation for events, separating each event with a vertical bar (|). Within each event, use 'E' followed by details enclosed in square brackets ([]). Separate details with semicolons (;). Include important details in brackets.
