Synthesizing guns

[hotdogPi]

Catagolue has the following guns in http://catagolue.hatsya.com/census/b3s2 ... sis-costs/
Gosper glider gun
Bi-gun
AK-94
p156

These should be possible to synthesize:
Other p30 and p46 guns
p16 (use a normal emulator rather than a bounding box-optimized one)
p22 (Jason's p22)
p24 (p6 thumb)
p25 (unnamed p5 that could probably be activated from a still life)
p16-assisted p32 (Rich's p16)
p40 (34P20 works in place of toaster)
p43 (16-cell still life)
p44 (house siamese shillelagh if using transparent blinker form)
p45, two types (pentadecathlons)
p48 (Rob's p16)
p49 (gourmet catalysts)
p51 (Spartan)
p52 (eater 2s)
p53 (build the large still life incrementally)
p60 (pentadecathlon, chucklebait OR five pentadecathlons)
p68 (unnamed p4)
p74 (chucklebait)
p88 (blockers and/or figure eights)
B-52 bomber (mold, blocker)
p113 (Spartan)
p143 (chucklebait)
p144 (unnamed medium-sized catalyst)
p201 (Spartan)
p246 (unix)
p46 gliderless LWSS and MWSS (Tanner's p46)

There isn't a particularly easy way to get a synthesis of a gun pattern into Catagolue, right? We either have to post a synthesis of a capped version of the gun using the nonmagical box.

-- Or, maybe alternatively, submit a pull request to Shinjuku?

[hotdogPi]

How are the existing ones there, then?

How are the existing ones there, then?

If I remember right, those four were maybe the only named gun patterns on the LifeWiki at one point, that had a "|synthesis = {N}" line in their infoboxes.

Somebody who understands the connection between Catagolue and Shinjuku better than I do, submitted one or more pull requests to to get those linear-growth pattern syntheses into the database.

If someone wants to submit a pull request for the above p48 gun synthesis, I'd definitely appreciate seeing a walkthrough of the process posted here. Here's some previous discussion where the process is described as "simply encode your syntheses in your local copy of Shinjuku".

Catagolue has the following guns in http://catagolue.hatsya.com/census/b3s2 ... sis-costs/
Gosper glider gun
Bi-gun
AK-94
p156

LifeWiki already has a synthesis for each of the following guns : AK-94, B-52 bomber, Bi-gun, Period-45 glider gun, Period-144 glider gun, Period-156 glider gun, Period-184 glider gun, Simkin glider gun, and a period-856 glider gun which is only in the pattern collection.
On Catagolue, there is also a capped p43 gun, xp43_w2egoy03pm0eik8y18k8z4s0gzw11xcujy8pf6xggzyo1074zy2252y1259e0djoy031e8 and a capped (with a boat-bit) p48 gun, xp96_0178cy766zy44koy6m640ooe4a4z0gs26x11xoy1oo022440ezo8go
There are likely more of them.

How are the existing ones there, then?

If I remember right, those four were maybe the only named gun patterns on the LifeWiki at one point, that had a "|synthesis = {N}" line in their infoboxes.

Somebody who understands the connection between Catagolue and Shinjuku better than I do, submitted one or more pull requests to to get those linear-growth pattern syntheses into the database.

If someone wants to submit a pull request for the above p48 gun synthesis, I'd definitely appreciate seeing a walkthrough of the process posted here. Here's some previous discussion where the process is described as "simply encode your syntheses in your local copy of Shinjuku".

Shinjuku doesn't contain syntheses of linear growth patterns, because apgcodes with 'yl' prefixes don't provide enough information to reconstruct the original pattern. Such syntheses are currently handled inside Catagolue's source code (see initialise/diffupdate.py).
However, I just tried to use Shinjuku with lifelib's new 'xg' prefixes for guns, and it appears to work correctly (before testing the following, change maxexp to 16 or some reasonnable value in the oscar call in shinjuku.tanscode.encode_comp, or it will take a while) :

Code: Select all

>>> from shinjuku.transcode import encode_comp, decode_comp, realise_comp
>>> comp = encode_comp("58bobo$58b2o$2bo56bo$3b2o$2b2o10$45bo$45bobo$45b2o19$20bo21bo$20bobo11b5o3bo$12bo7b2o12b2o3bo2bo$13b2o25bo$12b2o25b2o$35bo$36b2ob2o$39b2o3$2o$b2o$o31b2o$32bobo$32bo8$17b2o$18b2o$17bo32bo$49b2o$49bobo$44b2o$43b2o$45bo!")

It should be feasible to add a tabulation for gun syntheses to Catagolue without too much modification to the existing code.
