36 | /* Primitives provided by the program: | |
37 | ||
38 | Two stacks are provided, a string stack and an integer stack. | |
39 | ||
40 | Internal state variables: | |
41 | internal_wanted - indicates whether `-i' was passed | |
42 | internal_mode - user-settable | |
43 | ||
44 | Commands: | |
45 | push_text | |
46 | ! - pop top of integer stack for address, pop next for value; store | |
47 | @ - treat value on integer stack as the address of an integer; push | |
48 | that integer on the integer stack after popping the "address" | |
49 | hello - print "hello\n" to stdout | |
50 | stdout - put stdout marker on TOS | |
51 | stderr - put stderr marker on TOS | |
52 | print - print TOS-1 on TOS (eg: "hello\n" stdout print) | |
53 | skip_past_newline | |
54 | catstr - fn icatstr | |
55 | copy_past_newline - append input, up to and including newline into TOS | |
56 | dup - fn other_dup | |
57 | drop - discard TOS | |
58 | idrop - ditto | |
59 | remchar - delete last character from TOS | |
60 | get_stuff_in_command | |
61 | do_fancy_stuff - translate <<foo>> to @code{foo} in TOS | |
62 | bulletize - if "o" lines found, prepend @itemize @bullet to TOS | |
63 | and @item to each "o" line; append @end itemize | |
64 | courierize - put @example around . and | lines, translate {* *} { } | |
65 | exit - fn chew_exit | |
66 | swap | |
67 | outputdots - strip out lines without leading dots | |
68 | paramstuff - convert full declaration into "PARAMS" form if not already | |
69 | maybecatstr - do catstr if internal_mode == internal_wanted, discard | |
70 | value in any case | |
71 | translatecomments - turn {* and *} into comment delimiters | |
72 | kill_bogus_lines - get rid of extra newlines | |
73 | indent | |
74 | internalmode - pop from integer stack, set `internalmode' to that value | |
75 | print_stack_level - print current stack depth to stderr | |
76 | strip_trailing_newlines - go ahead, guess... | |
77 | [quoted string] - push string onto string stack | |
78 | [word starting with digit] - push atol(str) onto integer stack | |
79 | ||
80 | A command must be all upper-case, and alone on a line. | |
