| michael@0 | 6 | * shexp.h: Defines and prototypes for shell exp. match routines |
| michael@0 | 7 | * |
| michael@0 | 8 | * This routine will match a string with a shell expression. The expressions |
| michael@0 | 9 | * accepted are based loosely on the expressions accepted by zsh. |
| michael@0 | 10 | * |
| michael@0 | 11 | * o * matches anything |
| michael@0 | 12 | * o ? matches one character |
| michael@0 | 13 | * o \ will escape a special character |
| michael@0 | 14 | * o $ matches the end of the string |
| michael@0 | 15 | * Bracketed expressions: |
| michael@0 | 16 | * o [abc] matches one occurence of a, b, or c. |
| michael@0 | 17 | * o [^abc] matches any character except a, b, or c. |
| michael@0 | 18 | * To be matched between [ and ], these characters must be escaped: \ ] |
| michael@0 | 19 | * No other characters need be escaped between brackets. |
| michael@0 | 20 | * Unnecessary escaping is permitted. |
| michael@0 | 21 | * o [a-z] matches any character between a and z, inclusive. |
| michael@0 | 22 | * The two range-definition characters must be alphanumeric ASCII. |
| michael@0 | 23 | * If one is upper case and the other is lower case, then the ASCII |
| michael@0 | 24 | * non-alphanumeric characters between Z and a will also be in range. |
| michael@0 | 25 | * o [^a-z] matches any character except those between a and z, inclusive. |
| michael@0 | 26 | * These forms cannot be combined, e.g [a-gp-z] does not work. |
| michael@0 | 27 | * o Exclusions: |
| michael@0 | 28 | * As a top level, outter-most expression only, the expression |
| michael@0 | 29 | * foo~bar will match the expression foo, provided it does not also |
| michael@0 | 30 | * match the expression bar. Either expression or both may be a union. |
| michael@0 | 31 | * Except between brackets, any unescaped ~ is an exclusion. |
| michael@0 | 32 | * At most one exclusion is permitted. |
| michael@0 | 33 | * Exclusions cannot be nested (contain other exclusions). |
| michael@0 | 34 | * example: *~abc will match any string except abc |
| michael@0 | 35 | * o Unions: |
| michael@0 | 36 | * (foo|bar) will match either the expression foo, or the expression bar. |
| michael@0 | 37 | * At least one '|' separator is required. More are permitted. |
| michael@0 | 38 | * Expressions inside unions may not include unions or exclusions. |
| michael@0 | 39 | * Inside a union, to be matched and not treated as a special character, |
| michael@0 | 40 | * these characters must be escaped: \ ( | ) [ ~ except when they occur |
| michael@0 | 41 | * inside a bracketed expression, where only \ and ] require escaping. |
| michael@0 | 42 | * |
| michael@0 | 43 | * The public interface to these routines is documented below. |
