User:Apple Bottom/TODO

Tools for writing articles:

• Jason Summer's Oscillizer - for oscillators and still lifes (all rules)
• Mark Niemiec's Life Search - for all patterns (Conway Life only)

Notes:

• On Link* and Cite* templates: these exist not just to make linking to/citing certain sites easier, but also to avoid having to manually update hundreds (or thousands) of articles if a site moves.

General

TODO notes, ideas and so on, not necessarily just for myself.

• Apple Bot:
  • User:Apple Bot needs bot and trusted flags.
  • Edit applebot.pl to also read Bob Shemyakin's glider synthesis list.
  • Perhaps equip the script with the ability to update these data files from the web (--update), and to suggest doing so if they aren't found.
  • Automatically editing articles to reflect the best known glider syntheses isn't a good idea, as Dvgrn points out: the synthesis RLEs would also have to be updated.
  • MediaWiki::Bot has various warts, including an inability to log in (see issue 83). The author writes that it is unmaintained, but patches are welcome. Consider submitting one.

• Ongoing project: gather references on conwaylife.com.
  • Others are on this case.

• Catagolue browser extension:
  • Put this on Github.
  • Consider adapting it for other browsers, e.g. Firefox. (Or invite others to fork the repo and submit pull requests.)
  • Finish the jslife work, and release a new version including that.
    • Well, it's not finished, but at least it's released.
  • Rowett asked about including the LifeViewer. Great idea, but for licensing reasons (GPL) this would require unobfuscated code for the LifeViewer, which is not currently available.
  • Chris_C suggested (here) automatically generating glider syntheses for still lifes.
  • More in the extension's own TODO file.

• Glider synthesis generator CGI script:
  • Also basically Chris_C's suggestion. Something resembling Oscillizer, perhaps hosted on conwaylife.com? Someone else will have to handle this.

• Catagolue-related scripts and files:
  • Beat these into shape and put them on Github as appropriate.

• Catagolue:
  • Backups should go on archive.org.
  • Is there a public repo of the Catagolue codebase? Are pull requests accepted, e.g. to add a "list of all rules ever investigated" page?

• NaiveLife.pm, image_gen:
  • Beat these into shape and put them on Github.

LifeWiki TODO

Current

• The "Types of Greyships" section in Greyship needs to be updated/expanded. Several pages redirect to this; at the minimum all those terms should be mentioned and explained.

• Figure out a way of RSS-ifying Template:CurrentNews, and have User:Nathaniel add that feed to the conwaylife.com frontpage.

• Methuselahs:
  • Methuselahs with lifespan less than 10,000 (see List of long-lived methuselahs) do not have f= and mcps= filled in in their infoboxes.
  • Various methuselahs are missing descriptions/censuses of their final patterns.

• The various "category" templates (e.g. Template:OscillatorPeriod) all take differently-named parameters; this is confusing ("was it 't='? Or 'n='? Or 'c='? Or 's='? Or..."). Tweak all these to also (alternatively) accept a nameless parameter.

• Template:GrowingSpaceship does not categorize (and thus has no supporting category infrastructure) based on the extra parameters, fs, bs, fp and bp.
  • Should it? Unlike with e.g. oscillators, it might well be that most of these categories would only contain one article, so there might be no point in having them.
  • Same for Template:MovingBreeder.
  • And quite a few others.

• Software that needs articles:
  • osrc ("Preliminary attempt at a zfind-like oscillator searcher"), Aidan F. Pierce, [1]
  • ofind ("search for oscillators in semitotalistic cellular automata"), David Eppstein, [2]
  • lifelocallookahead (spaceship searcher), Andrew J. Wade, [3], [4]

• Noam Elkies, The still-Life density problem and its generalizations, depicts the following agars in Appendix A:
  • Chicken wire
  • TV static
  • Onion rings
  • Onion bulbs
  • Hoey I
  • Hoey II
  • Square waves
  • Moore
  • DCC onions
  • AB5 F' F'' octets
  • AB8 F'2 F'' dozens
• Also, Dave Greene mentions the blocks agar here.

• In Template:Oscillator, separate oscillator-specific parameters (period, heat, volatility etc.) into an "Oscillator parameters" section (like "Pattern files" etc.), expanded by default.
  • This will make the template less confusing/overloaded for users, and it will help with an eventual rebasing of the specific infobox templates on a generic "base" pattern template.
  • Same for Template:Spaceship.
  • ...and all the other specific pattern templates, such as Template:Gun, Template:Conduit, Template:Puffer etc.
  • This should probably be discussed at the LifeWiki:Tiki bar first.

• User:Scotgot appears to have used strict volatility instead of volatility for the v= parameter when creating oscillator pages. Check every such page they created and correct any wrong numbers.
  • Same for User:AwesoMan3000.

• Update the following RLE files to use rulestrings in B/S notation (i.e. "B3/S23", not "23/3" or "Life"); note that there might be others not listed here:
  • 112p51
  • 124p37
  • Tumbling T-tetson
  • Superfountain
  • Sailboat
  • Roteightor
  • Sixty-nine
  • Thumb 1
  • 35p52
  • Worker bee
  • Smiley
  • Kok's galaxy
  • Figure eight on 22p36
  • Figure eight on pentadecathlon
  • Pi orbital
  • Wavefront

• The cellular automaton article currently only talks about CAs defined on a square lattice. This needs to change; there are CAs on all sorts of tilings, both regular (hexagonal, triangular) and less regular (Penrose, hyperbolic, ...). We're currently fudging hexagonal tilings by defining a "hexagonal neighborhood" on the square lattice (e.g. creating a "bricklayer's tiling"); but while that's fine (software such as Golly does hexagonal CAs this way), it's essentially an implementation detail. It should be noted, but CAs should be treated more generally.
  • Related: the article currently goes on at length about both CAs in general and Life-like CAs in particular. This needs to be disentangled, and Life-like CAs given their own article that introduces the basic concepts as required to understand them and otherwise refers to the general cellular automaton article.

• Modify external link templates to all take title=, name=, pagename= and patternname= (as synonyms). It's not very useful for the parameters to have different names in different templates. (And some users even use entirely non-existent parameters without even so much as checking whether they do in fact have an effect.)

• For that matter, saner external link templates in general. No hidden surprises, no things that don't work (but should), no inconsistencies, no making-the-user-jump-through-hoops-to-use-them, and so on. (See Template talk:LinkForumThread.) Also, cleaner template code that is more conducive to being edited and doesn't present itself as a thorny thicket of punctuation.

• Write Tutorial:Writing LifeWiki articles ?

• Add an "identifiers" section to pattern infoboxes, listing e.g. apgcode, Niemiec number/identifier, Pentadecathlon (Koenig) identifier, stamp collection indices (jslife, DRH), and so on.
  • Create Template:PatternIdentifiers and use it in pattern infobox templates.
  • Add jslife/DRH/... stamp collection indices etc., in an appropriate manner.
  • Add identifiers to articles.
    • DONE: Boat on snake, 112P51.
    • DONE: apgcode=.
    • NOT DONE: everything else.

• (This is being discussed at the LifeWiki:Tiki bar.) Figure out how to best use LV:Viewer in articles in a way that's both useful, accessible, and well-integrated into the existing article layout.
  • Create Help:LifeViewer?

• (This is being discussed at the LifeWiki:Tiki bar.) Go through Category:Proposed deletion and decide what should be kept.

• Create missing articles for Life Lexicon entries, or redirect to existing ones (as appropriate). See below for a list.

• Go through pages for common objects.
  • Also make a {{CiteFlammenkampCensus}} citation template. Unnecessary, Template:citeAchim already exists
  • Move statements about how common they are to a new section, and note that the data is from Achim Flammenkamp's census.
    • Still lifes listed on List of common still lifes - DONE
    • Oscillators listed on List of common oscillators - DONE
    • Glider, LWSS, MWSS, HWSS, Glider-producing switch engine, Block-laying switch engine - DONE
  • Add data on common-ness from Catagolue.
  • If possible, find a copy of the results from Nathaniel's census and add data from that as well. (This is referenced on a few pages anyway. Check archive.org, or ask on the conwaylife.com forums.)
    • Discussion thread for this census: [5]
    • The last copy on archive.org dates from May 10, 2011, and lists 154 still lifes and oscillators, plus 4 spaceships. Images are broken, but the RLE encoded in the URLs can be used to identify (unnamed) patterns.
    • Unnamed patterns on this page are at User:Apple Bottom/Nathaniel's census (names via Catagolue).
    • Nathaniel himself may have a more recent and/or complete results. (He doesn't; data was lost in a server crash.)
    • Add data on commonness from Nathaniel's census.
  • There's also a census by Andrzej Okrasinski. Mentioned here. - DONE, thanks User:Lewis!
    • Last archive.org copy: 2009-10-27, [6]; PDF of results [7]
  • Were there any other censuses/soup-search efforts?

• Add a family= parameter for:
  • Oscillators
  • Spaceships
  • Still lifes
  • Patterns
  • Use it where appropriate.
  • Add the necessary supporting template/category infrastructure.

• Add Catagolue links (using Template:LinkCatagolue and style=brief) to pages transcluding Template:JavaRLE, currently:

Next/Later

• Make Template:GunNavbox and use it on Template:GunBarrelCategory, Template:GunPeriodCategory, Category:Guns with a specific number of barrels and Category:Guns with specific period.
  • Also look into making Template:GunNumbers à la Template:OscNumbers.

• Write articles for common patterns from Catagolue.
  • xp2: Monotub spark coil, xp2_og2t1e8z6221, anything rarer than #40 on my list
  • ...

• Make or consider making new pattern templates, along with the supporting template/category infrastructure for each, and use them where appropriate. Also add category links to Template:PatternMainNavbox ("minor types").
  • Template:Breeder (well, there's Template:MovingBreeder...)
  • Template:CaberTosser
  • Template:Conduit
  • Template:Converter
  • Template:GardenOfEden
  • Template:InductionCoil
  • Template:InfiniteGrowth - distinct from Template:Puffer?
  • Template:LoopOscillator - probably not necessary
  • Template:MutteringMoat - probably not necessary
  • Template:Reaction
  • Template:Seed
  • Template:ShuttleOscillator - probably not necessary
  • Template:Spacefiller
  • Template:Spark
  • Template:Superstring
  • Template:Tagalong
  • Template:UnitCell
  • Template:Waveguide

• Go through Category:Pages without pattern files and add raw RLE snippets where possibly/appropriate.
  • Many of these snippets are on User talk:Nathaniel.

• Where appropriate, move references out of main article text for further readability/editability.
  • See [8] for an example.

• Citation templates:
  • Make a {{CiteLifeLine}} template that can be used to cite LifeLine issues easily without resorting to {{cite web}}. - already exists.
  • Use Template:CiteLifeline where Lifeline is currently cited directly.
  • Make Template:CiteForumPost. Use Template:LinkForumThread, with format=ref.
    • Use it wherever Template:Cite web is currently used to cite forum posts.
    • Also use it where forum posts are referenced without a citation template.
  • Make a list of citation templates, transclude it in their documentation. Better yet, use DPL to generate it automatically.

• Make and use DPL templates for oscillator population and sawtooth population, as for oscillator periods and sawtooth expansion factors.
  • Also for other things?

• Most population 12 still lifes have no entries.
  • Given how many there are, consider discussing up to which size still lives should have entries at all.

• Make nicer-looking versions of the following images (and possibly others), and also consider giving them more informative names where appropriate:

  • Most files uploaded by User:AwesoMan3000

• Create images for pages in Category:Pages with broken file links.

• Various patterns are missing pattern files. Bug Nathaniel or the other admins about adding those.

• Outdated/orphaned pages in need of attention:
  • Game of Life statistics
  • Period 5 oscillators
  • Timeline of Life facts

• Transcribe further LifeLine issues.
  • Modulo community consensus, update existing transcriptions to use LifeViewer and on-wiki RLE snippets instead of static images.
  • Also see Lifeline/project.

• Add entries for various "well-known" (i.e. well-investigated) rules, especially named ones.

• Write articles for "Pattern of the Year" nominations (see ConwayLife.com forums). Any pattern thus nominated is clearly important.

• Write articles for various noteworthy oscillators; see Talk:Oscillator#Recent_records.

• (Perhaps) write articles for all patterns in the various "stamp collections" floating around, notably jslife and Dean Hickerson's stamp collections.

• Make sure all oscillators/spaceships have animated images, and create/upload missing ones.

• Add rule parameters to spaceship pages.

• Double-check oscillators starting with $, 0-9, A, B to make sure rulemin is correct.

• Add rulespecial= parameters to oscillators, still lifes and spaceships where appropriate.
  • Better yet, do away with rulespecial and autogenerate the data from rulemin and rulemax, using a list of candidate rules based on List of Life-like cellular automata.

• Add an "in other rules" section to pattern articles.

• Format infoboxes for books and articles.

• Make Template:CrawlerNavbox and use it on the crawler-related categories/templates instead of the generic PatternMainNavbox.

• Pages needing cleanup:
  • (13,1)c/31 Pseudo-B climber
  • (23,5)c/79 Herschel climber
  • (27,1)c/72 Herschel climber
  • (34,7)c/156 Herschel climber
  • 31c/240 reaction
  • Almost knightship
  • Cis-mirrored worm
  • Cis-mirrored worm siamese cis-mirrored worm
  • Flock (2x2 oscillator imgs)
  • Reciprocating agar
  • Very^3 long boat
  • Very^4 long boat
  • Very^5 long boat
  • Very^6 long boat
  • Very^7 long boat
  • Various pages created since ~2016-07-22; anything created/edited by User:AwesoMan3000

• Add a symmetry option to Template:Pattern (and related templates) and display the pattern's symmetry in the infobox, and also put patterns into the right symmetry category automatically.
  • This should be discussed at the Tiki bar first.

• Modify Template:Pattern (etc.) to allow specifying several discoverers.
  • Fix up articles currently doing this manually.
    • DONE, except: Heavyweight volcano, Pre-pulsar spaceship. See Tiki bar discussion.

• Add documentation to Template:cite web.

• (?) Rebase Template:Pattern etc. on a generic Template:Infobox.
  • This is a disruptive change that should gain consensus at the Tiki bar first.

Stalled

• Add Template:LinkCatagolue on object's pages.
  • Still lifes:
    • Up to 10 bits - DONE; all objects have entries
    • 11 bits and more - DONE all objects with entries have the right templates
  • Oscillators - DONE, except:
    • Interchange, Killer toads, Traffic light - NOT DONE, pseudo objects
    • P57 Herschel loop 1, P59 Herschel loop 1, P61 Herschel loop 1, - NOT DONE, too large; although these can be encoded in extended form, Catagolue cannot currently handle the resulting codes.
    • P59 Herschel loop 2, P61 Herschel loop 2 - NOT DONE, no pattern files
  • Spaceships - DONE, except:
    • Caterloopillar, Caterpillar, Centipede, Demonoid, Gemini, Half-baked knightship, Parallel HBK, Shield bug, Waterbear - NOT DONE, too large
    • (L|M|H)WSS flotillae - DONE
  • Puffers:
    • Block-laying switch engine, Glider-producing switch engine, Pufferfish, Pony express - DONE
    • Everything else - NOT DONE

• Use Template:LinkLexicon instead of hardcoded Life Lexicon links - DONE, except for the occasional stray link not in the search index
  • Grab an XML dump of the current revisions and grep through it to find any remaining links.
  • DONE, except:
    • Filter, Plaintext, Spaceship terminology, Stephen Silver, Types of spaceship, LifeWiki:Life links, LifeWiki:Task list: not sure right now how to best avoid direct links there.
    • Talk:Pi ship, Talk:Triple pseudo still life - NOT DONE, talk pages
    • User:Sokwe - NOT DONE, user page
    • Template:CiteLexicon, Template:LinkLexicon - obviously these have to use direct links.

• Check oscillator pages and ensure the infoboxes have rulemin and rulemax parameters.
  • Bit for cutting and pasting: |rulespecial=[[Conway's Game of Life|Conway Life]]|rulemin=B3/S23|rulemax=. But keep in mind some oscillators do in fact work in "lower" rules such as B3/S3 (clock) or B3/S2 (blinker, fox, killer toads, toad, traffic light).
  • Use Oscillizer to figure these out if not. Note that Oscillizer chokes on rule specs in S/B notation (e.g. 23/3); they have to be in B/S notation (e.g. B3/S23).
  • DONE, except for:
    • P59 Herschel loop 1, P61 Herschel loop 1 - NOT DONE, too large for Oscillizer
    • P59 Herschel loop 2, P61 Herschel loop 2 - NOT DONE, no RLE

• Create Template:LinkPentadecathlonObject
  • ...and start using it.

• Most population 11 still lifes have no entries.
  • Resources:
    • Category:Strict still lifes with 11 cells - current entries
    • xs11 on Catagolue - complete list
    • Niemiec - complete list
  • Create and upload images - DONE
  • Write articles, create redirects - DONE
  • Have Nathaniel add patterns for the objects and their syntheses - NOT DONE

Done

• Create and use Template:LinkCellebration - DONE
  • Actually, replaced by Template:LinkMirek.
• Create and use Template:LinkCallahan - DONE, I believe
• Create and use Template:LinkForumThread - DONE (for Main namespace articles anyway)

• The following gliders in David Eppstein's DB don't seem to have articles:
  • http://fano.ics.uci.edu/ca/gliders/g16485.html
  • http://fano.ics.uci.edu/ca/gliders/g16532.html

• Use DPL to automatically populate the list of link templates.

• Add rule parameters to still lifes. - DONE
  • Oscillizer also works for these, since they're really p1 oscillators.
  • Snippet: |rulespecial=[[Conway's Game of Life|Conway Life]]|rulemin=B/S23|rulemax=B/S012345678. Fill in B conditions for rulemax. Note: rulemin may also be B/S2 or B/S3.

• Use {{CiteLexicon}} where appropriate.
  • Grep an XML dump of the current revisions to find what needs updating.

• Put a {{DISPLAYTITLE}} on pages like P11 double-length signal injector to avoid capitalizing the "p". Also adjust infobox names if necessary.

• LifeWiki:Tiki bar

• Make images for Symmetry illustrating the various kinds of symmetry, à la Alexey Nigin in the linked thread.

• Format infobox transclusions on pattern pages for readability/editability.
  • See [9] for an example.
  • Make a local helper script to handle this.
  • Category:Patterns: $, 1-9, A-Z - DONE

• Rewrite/edit:
  • Broken lines

• Last two top 100 objects on Catagolue without articles:
  • Cis-mirrored R-mango (#89)
  • Cis-mirrored R-loaf (#92)

• LifeWiki:Did you know/25 is out of date; Sawtooth 177 is smaller.
• Template:SpaceshipNavbox should list Category:Spaceships with specific direction and Category:Spaceships with specific slope.
• Template:Disambig should put pages into Category:Disambiguation pages.
• The following categories should be placed in Category:Pattern categories:
  • Category:Still lifes
  • Category:Reflectors
  • Category:Pure glider generators
  • Category:Puffer engines
  • Category:Pseudo still lifes
  • Category:Patterns
  • Category:Induction coils
  • Category:Eaters
• The following category should be placed in Category:Toplevel category:
  • Category:Everything else
• Template:Gun should categorize guns according to their periods.
• Add a parameter indicating the number of barrels to Template:Gun.
• Add "family" parameter to Template:Stilllife and Template:Pattern, à la Template:Oscillator and Template:Spaceship.
  • Add links to family category and important families to Template:OscillatorNavbox, à la Template:SpaceshipNavbox.
• Main Page lists all.zip as a 2 MiB file; it's actually 45.7 MiB right now.
• Template:PatternNavbox is missing a number of "other categories".
• Template:PatternDownload should handle cases where rulemin or rulespecial is passed but not rulemax without printing e.g. "# of rules: 2^-6 = 0.015625".

• Merge Template:CatagolueBrief into Template:LinkCatagolue and add a style= parameter to control how Catagolue links are formatted, e.g. style=listitem (default), style=brief, etc.

• The RLE/Plaintext/Life 1.05/Life 1.06 files for Killer candlefrobras are wrong, encoding the "Killer candlefrobras eating an HWSS" reaction instead of the pattern itself.

Needs admin assistance

• Install the InputBox extension and create preload templates for oscillators, spaceships, still lifes, rules etc. to make it easier for non-techies to contribute pages.
  • See User:Apple Bottom/Page Creation Box for how a template using the extension, and User:Apple Bottom/Create a page for an example of how the template might be used.

General ideas for LifeWiki

• Would be nice to have better integration of RLE. Perhaps an extension to handle it, either in its own namespace (RLE:) or as parser tags (<rle>). Images could also be auto-generated from RLE then. Extension:EasyTimeline might serve as a base.
• LifeViewer integration would also be nice, ideally tied into the above. See [10], [11].
• Information on patterns etc. could additionally be encoded in a semantic format to facilitate automated processing. See [12]. Alternatively, would a Wikidata-like repo of facts be useful?
  • This could be done in Template:Pattern etc., and would be transparent to human users; articles would still render as before, and their source text wouldn't need to be changed.
  • What would be the best solution for this? Generating machine-readable data in some XML- or JSON-based microformat, Semantic Mediawiki, or a Wikidata-like repository?
• Would be nice to handle other rules in some way.
  • How would articles be named? Prefixes/namespaces (e.g. HighLife:Bomber or B36/S23:Bomber)? Suffixes (e.g. Bomber (HighLife) or Bomber (B36/S23))? What about patterns that work in several important rules, such as the Moon (which is in both Seeds and Live Free or Die, not to mention various other B2 rules)?
  • How would pattern categories work? Different category trees for each rule?
  • Might be better to keep wikis for different rules separate (though they could share the same MediaWiki codebase, the way that the Wikimedia Foundation runs many different wikis). But this would lead to duplication of effort for templates etc. Would a central template repository be useful? (What if different wikis want to tweak the same template in different ways? The repo could act as a shadow repo only providing templates not present locally, but this would still mean templates would likely diverge instead of being edited globally.)
• MediaWiki supports Lua scripting. Would be good to have, to replace the more complicated templates and to do things difficult to do with templates at all.
• Combatting spam:
  • MediaWiki has various rate-limiting features etc. to combat spam. These could perhaps be used to do away with the "you manually have to request the trusted flag to edit" bit.
  • Alternatively, or in addition, it's possible to limit editing to auto-confirmed users.
  • There's also stable versions and patrolling.
