| 59 * The "internal use only" fields in regexp.h are present to pass info from | |
| 60 * compile to execute that permits the execute phase to run lots faster on | |
| 61 * simple cases. They are: | |
| 62 * | |
| 63 * regstart char that must begin a match; NUL if none obvious; Can be a | |
| 64 * multi-byte character. | |
| 65 * reganch is the match anchored (at beginning-of-line only)? | |
| 66 * regmust string (pointer into program) that match must include, or NULL | |
| 67 * regmlen length of regmust string | |
| 68 * regflags RF_ values or'ed together | |
| 69 * | |
| 70 * Regstart and reganch permit very fast decisions on suitable starting points | |
| 71 * for a match, cutting down the work a lot. Regmust permits fast rejection | |
| 72 * of lines that cannot possibly match. The regmust tests are costly enough | |
| 73 * that vim_regcomp() supplies a regmust only if the r.e. contains something | |
| 74 * potentially expensive (at present, the only such thing detected is * or + | |
| 75 * at the start of the r.e., which can involve a lot of backup). Regmlen is | |
| 76 * supplied because the test in vim_regexec() needs it and vim_regcomp() is | |
| 77 * computing it anyway. | |
| 78 */ | |
| 79 | |
| 80 /* | |
| 81 * Structure for regexp "program". This is essentially a linear encoding | |
| 82 * of a nondeterministic finite-state machine (aka syntax charts or | |
| 83 * "railroad normal form" in parsing technology). Each node is an opcode | |
| 84 * plus a "next" pointer, possibly plus an operand. "Next" pointers of | |
| 85 * all nodes except BRANCH and BRACES_COMPLEX implement concatenation; a "next" | |
| 86 * pointer with a BRANCH on both ends of it is connecting two alternatives. | |
| 87 * (Here we have one of the subtle syntax dependencies: an individual BRANCH | |
| 88 * (as opposed to a collection of them) is never concatenated with anything | |
| 89 * because of operator precedence). The "next" pointer of a BRACES_COMPLEX | |
| 167 | 90 * node points to the node after the stuff to be repeated. |
| 91 * The operand of some types of node is a literal string; for others, it is a | |
| 92 * node leading into a sub-FSM. In particular, the operand of a BRANCH node | |
| 93 * is the first node of the branch. | |
| 94 * (NB this is *not* a tree structure: the tail of the branch connects to the | |
| 95 * thing following the set of BRANCHes.) | |
| 7 | 96 * |
| 97 * pattern is coded like: | |

| 284 * | |
| 285 * BRANCH The set of branches constituting a single choice are hooked | |
| 286 * together with their "next" pointers, since precedence prevents | |
| 287 * anything being concatenated to any individual branch. The | |
| 288 * "next" pointer of the last BRANCH in a choice points to the | |
| 289 * thing following the whole choice. This is also where the | |
| 290 * final "next" pointer of each individual branch points; each | |
| 291 * branch starts with the operand node of a BRANCH node. | |
| 292 * | |
| 293 * BACK Normal "next" pointers all implicitly point forward; BACK | |
| 294 * exists to make loop structures possible. | |
| 295 * | |
| 296 * STAR,PLUS '=', and complex '*' and '+', are implemented as circular | |
| 297 * BRANCH structures using BACK. Simple cases (one character | |
| 298 * per match) are implemented with STAR and PLUS for speed | |
| 299 * and to minimize recursive plunges. | |
| 300 * | |
| 301 * BRACE_LIMITS This is always followed by a BRACE_SIMPLE or BRACE_COMPLEX | |
| 302 * node, and defines the min and max limits to be used for that | |

| 1323 * generation turned off and size counting turned on, and once "for real". | |
| 1324 * This also means that we don't allocate space until we are sure that the | |
| 1325 * thing really will compile successfully, and we never have to move the | |
| 1326 * code and thus invalidate pointers into it. (Note that it has to be in | |
| 1327 * one piece because vim_free() must be able to free it all.) | |
| 1328 * | |
| 1329 * Whether upper/lower case is to be ignored is decided when executing the | |
