Module:MaroScaleSandbox

From MTG Wiki
Revision as of 18:46, 4 July 2022 by >Jerodast (Remainder of comments, and some rephrasings now that I understand Lua better. Major code changes would be renaming a few vars and, what I'm especially curious about, removing the section that pre-loads all expected arguments up to MAX_ENTRIES)
Jump to navigation Jump to search

This is a sandbox page for experimenting with the Module:MaroScale lua script. Click for /doc access.

Goals:

  • Learn a bit more how it's used/about Modules
  • Make some updates/improvements (see script comments for details)

User:jerodast (talk) will request to delete this page once any useful changes are merged to core MaroScale page.

Since this module gets arguments from frame:getParent(), its use is best exemplified / tested via the calling template. These examples don't use real references, which in practice would be true citations with a full reference footnote. In these examples, ratings will always be EXPECTED to be in ascending order once sorted by date, to easily verify correctness.

Let's put[a] in some[b] fake footnotes to test compatibility of tables & other footnotes.[c]

--[[ Sandbox page for the MaroScale lua script

jerodast will request to delete this page once any useful changes are merged to
  the live MaroScale page

Goals for jerodast:
  * learn a bit more how it's used, AND about Modules in general
  * update LEGAL_EXPANSIONS
  * allow for not-a-single-number phrasings to be given an approximate number
      for sorting but still display, e.g. "about a 9" (treated as 9) or
      "7 or 8" (treated as 7.5)
  * explore possibility of having dates show up in the list of ratings changes,
      since the current simple serial list presentation makes ratings appear
      uniformly spaced when they're not
  * add column for additional notes - note that Beeble Scale crams notes into
      Timeline column already
