44 | /* |
45 | * At first glance the rules appeared to be: |
46 | * |
47 | * - Single quotes are not special characters. |
48 | * |
49 | * - Double quotes are removed, but within them spaces cease |
50 | * to be special. |
51 | * |
52 | * - Backslashes are _only_ special when a sequence of them |
53 | * appear just before a double quote. In this situation, |
54 | * they are treated like C backslashes: so \" just gives a |
55 | * literal quote, \\" gives a literal backslash and then |
56 | * opens or closes a double-quoted segment, \\\" gives a |
57 | * literal backslash and then a literal quote, \\\\" gives |
58 | * two literal backslashes and then opens/closes a |
59 | * double-quoted segment, and so forth. Note that this |
60 | * behaviour is identical inside and outside double quotes. |
61 | * |
62 | * - Two successive double quotes become one literal double |
63 | * quote, but only _inside_ a double-quoted segment. |
64 | * Outside, they just form an empty double-quoted segment |
65 | * (which may cause an empty argument word). |
66 | * |
67 | * - That only leaves the interesting question of what happens |
68 | * when one or more backslashes precedes two or more double |
69 | * quotes, starting inside a double-quoted string. And the |
70 | * answer to that appears somewhat bizarre. Here I tabulate |
71 | * number of backslashes (across the top) against number of |
72 | * quotes (down the left), and indicate how many backslashes |
73 | * are output, how many quotes are output, and whether a |
74 | * quoted segment is open at the end of the sequence: |
75 | * |
76 | * backslashes |
77 | * |
78 | * 0 1 2 3 4 |
79 | * |

95 | * [Test fragment was of the form "a\\\"""b c" d.] |
96 | * |
97 | * There is very weird mod-3 behaviour going on here in the |
98 | * number of quotes, and it even applies when there aren't any |
99 | * backslashes! How ghastly. |
100 | * |
101 | * With a bit of thought, this extremely odd diagram suddenly |
102 | * coalesced itself into a coherent, if still ghastly, model of |
103 | * how things work: |
104 | * |
105 | * - As before, backslashes are only special when one or more |
106 | * of them appear contiguously before at least one double |
107 | * quote. In this situation the backslashes do exactly what |
108 | * you'd expect: each one quotes the next thing in front of |
109 | * it, so you end up with n/2 literal backslashes (if n is |
110 | * even) or (n-1)/2 literal backslashes and a literal quote |
111 | * (if n is odd). In the latter case the double quote |
112 | * character right after the backslashes is used up. |
113 | * |
114 | * - After that, any remaining double quotes are processed. A |
115 | * string of contiguous unescaped double quotes has a mod-3 |
116 | * behaviour: |
117 | * |
118 | * * inside a quoted segment, a quote ends the segment. |
119 | * * _immediately_ after ending a quoted segment, a quote |
120 | * simply produces a literal quote. |
121 | * * otherwise, outside a quoted segment, a quote begins a |
122 | * quoted segment. |
123 | * |
124 | * So, for example, if we started inside a quoted segment |
125 | * then two contiguous quotes would close the segment and |
126 | * produce a literal quote; three would close the segment, |
127 | * produce a literal quote, and open a new segment. If we |
128 | * started outside a quoted segment, then two contiguous |
129 | * quotes would open and then close a segment, producing no |
130 | * output (but potentially creating a zero-length argument); |
131 | * but three quotes would open and close a segment and then |
132 | * produce a literal quote. |
