Revision as of 15:17, 22 August 2011
Present a program which emits the lyrics to the song I Knew an Old Lady Who Swallowed a Fly, taking advantage of the repetitive structure of the song's lyrics.

Boring, ad hoc dictionary based decompression. The encoder was arguably more interesting, though. Output is different from listing in talk page in punctuations and capitalizations. <lang c>#include <stdio.h>

Forth
swallow-addr is obviously a good candidate for an object, but Forth has many OO candidates - we won't settle that argument here.
<lang forth>: string, ( c-addr u -- ) \ store string at HERE , with a count
dup c, here swap dup allot move ;
\ doubly linked list: (0|prev, 0|next, aside?, cstr animal; cstr aside) \ aside? is true if the aside is always displayed. variable swallowed variable first
- >next ( swallow-addr -- swallow-addr' )
cell+ @ ;
- >aside? ( swallow-addr -- f )
2 cells + @ ;
- >animal ( swallow-addr -- c-addr u )
3 cells + count ;
- >aside ( swallow-addr -- c-addr u )
>animal + count ;
- swallow ( "animal" -- )
align swallowed @ if here swallowed @ cell+ ! else here first ! then here swallowed @ , swallowed ! 0 , 0 , parse-word string, ; \ data structure still needs the aside
- always ( -- ) \ set aside? of last-defined swallow to true
swallowed @ 2 cells + on ;
- aside ( "aside" -- )
0 parse string, ;
swallow fly always aside But I don't know why she swallowed the fly, swallow spider always aside That wriggled and jiggled and tickled inside her; swallow bird aside Quite absurd, she swallowed the bird; swallow cat aside Fancy that, she swallowed the cat; swallow dog aside What a hog, she swallowed the dog; swallow pig aside Her mouth was so big, she swallowed the pig; swallow goat aside She just opened her throat, she swallowed the goat; swallow cow aside I don't know how, she swallowed the cow; swallow donkey aside It was rather wonky, she swallowed the donkey;
- ?aside ( swallow-addr -- ) \ print aside if aside? is true
dup >aside? if >aside cr type else drop then ;
- reasons ( swallow-addr -- ) \ print reasons she swallowed something
begin dup @ while dup cr ." She swallowed the " >animal type ." to catch the " @ dup >animal type ." ," dup ?aside repeat drop ;

Icon and Unicon
This version isn't as compressed as some of the others but it is very straightforward to modify. Just add a new long and terse verse entry and amend the line marked order. This uses a feature of Icon/Unicon that allows procedures to be called with a list datatype instead of an argument list, so we just pre-build argument lists for printf.
<lang Icon>procedure main() #: There Was An Old Lady Lyrics
verse := table() # arglists for printf - [1] long asides and [2] terse joiners verse["bird"] := [["%s,\nQuite absurd, %s %s;\n",1,2,1],["%s,\n",1]] verse["cat"] := [["%s,\nFancy that, %s %s;\n",1,2,1],["%s,\n",1]] verse["dog"] := [["%s,\nWhat a hog, %s %s;\n",1,2,1],["%s,\n",1]] verse["pig"] := [["%s,\nHer mouth was so big, %s %s;\n",1,2,1],["%s,\n",1]] verse["goat"] := [["%s,\nShe just opened her throat, %s %s;\n",1,2,1],["%s,\n",1]] verse["cow"] := [["%s,\nI don't know how, %s %s;\n",1,2,1],["%s,\n",1]] verse["donkey"] := [["%s,\nIt was rather wonky, %s %s;\n",1,2,1],["%s,\n",1]]
# just long versions of these
verse["fly"] := "%s,\nBut I don't know why %s %s,\nPerhaps she'll die!\n\n",1,2,1 verse["spider"] := "%s,\nThat wriggled and jiggled and tickled inside her;\n",1 verse["horse"] := "%s...\nShe's dead, of course!\n",1
every (f := verse[k := key(verse)][1|2])[i := 1 to *f] do # fix every printf args
f[i] := case f[i] of { 1 : k ; 2 : "she swallowed the"; default : f[i]}
zoofilo := [] "fly,spider,bird,cat,dog,pig,goat,cow,donkey,horse," ? # order
while push(zoofilo,tab(find(","))) & move(1) do {
printf("There was an old lady who swallowed a ")
every critter := !zoofilo do {
printf!verse[critter,(critter == (zoofilo[1] | "spider" | "fly"),1)|2]
if critter == "horse" then stop() # dead
printf("She swallowed the %s to catch the ","fly" ~== critter)
}
}
end
