  1. Go to 'https://loom.shalott.org/learndb.html 'to see all the topics on one page.
  2. The main commands for the learndb are add, query, edit, swap, and delete. See [3] for add and insert, [4] and [5] for edit, [6] for query, [7] for swap and move. You can read entries in private queries to Sequell. You cannot change it in private, however.
  3. "!learn add article_name article text" adds an article to the learndb. !learn insert article_name[index] text adds an entry with a specific index.
  4. "!learn edit name[index] s/REGEX/REPLACE/opts" allows you to edit entries in the learndb. Regex refers to the portion of text you are editing, and replace refers to the text you are replacing the edited material with. Continued in learndb[5].
  5. Some characters are considered special when in the REGEX, and must be "escaped" with a backslash (eg. \ ( and ].) An escaped backslash would be \\. Sequell uses the forward slash also as a delimiter. To use the forward slash in REGEX, use the underscore as the delimiter (eg. !learn edit math[1] s_divide by_/.) For description of REGEX syntax visit 'https://code.google.com/p/re2/wiki/Syntax'
  6. "!learn query term" is approximately equivalent to ??term. Both forms support [$] for the last entry, or [-3] for the third from the end.
  7. !learn swap entry1 entry2 swaps two entries' order numbers. !learn mv foo bar moves an entry.

  9. The database can only be changed from the #crawl channel on Libera IRC or the {roguelikes discord} server. See 'https://libera.chat 'and the webclient at 'https://web.libera.chat/#crawl'
  10. woefully out of date
