/* * shexp . h : Defines and prototypes for shell exp . match routines * * This routine will match a string with a shell expression . The expressions * accepted are based loosely on the expressions accepted by zsh . * * o * matches anything * o ? matches one character * o \ will escape a special character * o $ matches the end of the string * Bracketed expressions : * o [ abc ] matches one occurence of a , b , or c . * o [ ^ abc ] matches any character except a , b , or c . * To be matched between [ and ] , these characters must be escaped : \ ] * No other characters need be escaped between brackets . * Unnecessary escaping is permitted . * o [ a - z ] matches any character between a and z , inclusive . * The two range - definition characters must be alphanumeric ASCII . * If one is upper case and the other is lower case , then the ASCII * non - alphanumeric characters between Z and a will also be in range . * o [ ^ a - z ] matches any character except those between a and z , inclusive . * These forms cannot be combined , e . g [ a - gp - z ] does not work . * o Exclusions : * As a top level , outter - most expression only , the expression * foo ~ bar will match the expression foo , provided it does not also * match the expression bar . Either expression or both may be a union . * Except between brackets , any unescaped ~ is an exclusion . * At most one exclusion is permitted . * Exclusions cannot be nested ( contain other exclusions ) . * example : * ~ abc will match any string except abc * o Unions : * ( foo | bar ) will match either the expression foo , or the expression bar . * At least one ' | ' separator is required . More are permitted . * Expressions inside unions may not include unions or exclusions . * Inside a union , to be matched and not treated as a special character , * these characters must be escaped : \ ( | ) [ ~ except when they occur * inside a bracketed expression , where only \ and ] require escaping . * * The public interface to these routines is documented below . *
