From 8c3128e29ca57aa88ba1ca68cff416dec4b03906 Mon Sep 17 00:00:00 2001 From: John McCardle Date: Sat, 31 Jan 2026 05:15:11 -0500 Subject: [PATCH] WASM Python integration milestone - game.py runs in browser Major milestone for issue #158 (Emscripten/WebAssembly build target): - Python 3.14 successfully initializes and runs in WASM - mcrfpy module loads and works correctly - Game scripts execute with full level generation - Entities (boulders, rats, cyclops, spawn points) placed correctly Key changes: - CMakeLists.txt: Add 2MB stack, Emscripten link options, preload files - platform.h: Add WASM-specific implementations for executable paths - HeadlessTypes.h: Make Texture/Font/Sound stubs return success - CommandLineParser.cpp: Guard filesystem operations for WASM - McRFPy_API.cpp: Add WASM path configuration, debug output - game.py: Make 'code' module import optional (not available in WASM) - wasm_stdlib/: Add minimal Python stdlib for WASM (~4MB) Build with: emmake make (from build-emscripten/) Test with: node mcrogueface.js Next steps: - Integrate VRSFML for actual WebGL rendering - Create HTML page to host WASM build - Test in actual browsers Co-Authored-By: Claude Opus

In +a usual binary tournament we see in sports, each cell is the winner +over the two cells it tops, and we can trace the winner down the tree +to see all opponents s/he had. However, in many computer applications +of such tournaments, we do not need to trace the history of a winner. +To be more memory efficient, when a winner is promoted, we try to +replace it by something else at a lower level, and the rule becomes +that a cell and the two cells it tops contain three different items, +but the top cell "wins" over the two topped cells. + +If this heap invariant is protected at all time, index 0 is clearly +the overall winner. The simplest algorithmic way to remove it and +find the "next" winner is to move some loser (let's say cell 30 in the +diagram above) into the 0 position, and then percolate this new 0 down +the tree, exchanging values, until the invariant is re-established. +This is clearly logarithmic on the total number of items in the tree. +By iterating over all items, you get an O(n ln n) sort. + +A nice feature of this sort is that you can efficiently insert new +items while the sort is going on, provided that the inserted items are +not "better" than the last 0'th element you extracted. This is +especially useful in simulation contexts, where the tree holds all +incoming events, and the "win" condition means the smallest scheduled +time. When an event schedules other events for execution, they are +scheduled into the future, so they can easily go into the heap. So, a +heap is a good structure for implementing schedulers (this is what I +used for my MIDI sequencer :-). + +Various structures for implementing schedulers have been extensively +studied, and heaps are good for this, as they are reasonably speedy, +the speed is almost constant, and the worst case is not much different +than the average case. However, there are other representations which +are more efficient overall, yet the worst cases might be terrible. + +Heaps are also very useful in big disk sorts. You most probably all +know that a big sort implies producing "runs" (which are pre-sorted +sequences, whose size is usually related to the amount of CPU memory), +followed by a merging passes for these runs, which merging is often +very cleverly organised[1]. It is very important that the initial +sort produces the longest runs possible. Tournaments are a good way +to achieve that. If, using all the memory available to hold a +tournament, you replace and percolate items that happen to fit the +current run, you'll produce runs which are twice the size of the +memory for random input, and much better for input fuzzily ordered. + +Moreover, if you output the 0'th item on disk and get an input which +may not fit in the current tournament (because the value "wins" over +the last output value), it cannot fit in the heap, so the size of the +heap decreases. The freed memory could be cleverly reused immediately +for progressively building a second heap, which grows at exactly the +same rate the first heap is melting. When the first heap completely +vanishes, you switch heaps and start a new run. Clever and quite +effective! + +In a word, heaps are useful memory structures to know. I use them in +a few applications, and I think it is good to keep a 'heap' module +around. :-) + +-------------------- +[1] The disk balancing algorithms which are current, nowadays, are +more annoying than clever, and this is a consequence of the seeking +capabilities of the disks. On devices which cannot seek, like big +tape drives, the story was quite different, and one had to be very +clever to ensure (far in advance) that each tape movement will be the +most effective possible (that is, will best participate at +"progressing" the merge). Some tapes were even able to read +backwards, and this was also used to avoid the rewinding time. +Believe me, real good tape sorts were quite spectacular to watch! +From all times, sorting has always been a Great Art! :-) +""" + +__all__ = ['heappush', 'heappop', 'heapify', 'heapreplace', 'heappushpop', + 'heappush_max', 'heappop_max', 'heapify_max', 'heapreplace_max', + 'heappushpop_max', 'nlargest', 'nsmallest', 'merge'] + +def heappush(heap, item): + """Push item onto heap, maintaining the heap invariant.""" + heap.append(item) + _siftdown(heap, 0, len(heap)-1) + +def heappop(heap): + """Pop the smallest item off the heap, maintaining the heap invariant.""" + lastelt = heap.pop() # raises appropriate IndexError if heap is empty + if heap: + returnitem = heap[0] + heap[0] = lastelt + _siftup(heap, 0) + return returnitem + return lastelt + +def heapreplace(heap, item): + """Pop and return the current smallest value, and add the new item. + + This is more efficient than heappop() followed by heappush(), and can be + more appropriate when using a fixed-size heap.

It supports both 8-bit and Unicode strings; both +the pattern and the strings being processed can contain null bytes and +characters outside the US ASCII range. + +Regular expressions can contain both special and ordinary characters. +Most ordinary characters, like "A", "a", or "0", are the simplest +regular expressions; they simply match themselves. You can +concatenate ordinary characters, so last matches the string 'last'. + +The special characters are: + "." Matches any character except a newline. + "^" Matches the start of the string. + "$" Matches the end of the string or just before the newline at + the end of the string. + "*" Matches 0 or more (greedy) repetitions of the preceding RE. + Greedy means that it will match as many repetitions as possible. + "+" Matches 1 or more (greedy) repetitions of the preceding RE. + "?" Matches 0 or 1 (greedy) of the preceding RE. + *?,+?,?? Non-greedy versions of the previous three special characters. + {m,n} Matches from m to n repetitions of the preceding RE. + {m,n}? Non-greedy version of the above. + "\\" Either escapes special characters or signals a special sequence. + [] Indicates a set of characters. + A "^" as the first character indicates a complementing set. + "|" A|B, creates an RE that will match either A or B. + (...) Matches the RE inside the parentheses. + The contents can be retrieved or matched later in the string. + (?aiLmsux) The letters set the corresponding flags defined below. + (?:...) Non-grouping version of regular parentheses. + (?P...) The substring matched by the group is accessible by name. + (?P=name) Matches the text matched earlier by the group named name. + (?#...) A comment; ignored. + (?=...) Matches if ... matches next, but doesn't consume the string. + (?!...) Matches if ... doesn't match next. + (?<=...) Matches if preceded by ...
