| class REGEXP |
|---|
| **** | < $FINALIZE Sather frontend for regular expressions. As specified in POSIX draft 1003.2/D11.2. |
| attr c_str: STR; |
|---|
| **** | Regular expression in POSIX syntax. |
| attr ignore_case: BOOL; |
|---|
| **** | True, if regular expression does not respect the case. |
| any_times: SAME |
|---|
| **** | Returns a regular expression matching self in zero or more occurences. |
| atleast(i:INT): SAME |
|---|
| **** | Returns a regular expression matching self in at least i occurences. |
| atmost(i:INT): SAME |
|---|
| **** | Returns a regular expression matching self in zero or at most 'i' occurences. |
| beginning: SAME |
|---|
| **** | Returns a regular expression matching the beginning of the string. |
| between(i,j:INT): SAME |
|---|
| **** | Returns a regular expression matching self in between 'i' and 'j' occurences. |
| char: SAME |
|---|
| **** | Returns a regular expression matching one arbitrary char. |
| compile |
|---|
| **** | Preparation of a regular expression to be used in 'match'. If not called before, will be called automatically on the first call to 'match'. |
| digit: SAME |
|---|
| **** | Returns a regular expression matching '0', '1' .. or '9'. |
| ending: SAME |
|---|
| **** | Returns a regular expression matching the end of a string. |
| letter: SAME |
|---|
| **** | Returns a regular expression matching 'a' .. 'z' or 'A' .. 'Z' |
| lowercase: SAME |
|---|
| **** | Returns a regular expression matching 'a', 'b' .. or 'z' |
| match( s:STR ): BOOL |
|---|
| **** | Peturns true if the string 's' is being accepted by the regular expression |
| match( s:STR, out from: INT, out to: INT ) |
|---|
| **** | Peturns the first position of 'string' matching the regular and the position of the first character after the match. 'from' and 'to' are -1 when no match is found. |
| nocase: SAME |
|---|
| **** | Returns a regular expression as self but ignoring the case |
| noneof(s:STR): SAME |
|---|
| **** | Returns a regular expression matching none of the chars in 's'. |
| oneof(s:STR): SAME |
|---|
| **** | Returns a regular expression matching one of the chars in 's'. |
| plus( r:SAME ): SAME |
|---|
| **** | Returns a regular expression matching self or r. Ignores the case when one of the subexpressions ignores the case. |
| pow( r:SAME ): SAME |
|---|
| **** | Returns a regular expression machting self and then r. Ignores the case when one of the subexpressions ignores the case. |
| regexp(s:STR,ignorecase:BOOL): SAME |
|---|
| **** | Passing a regular expression directly from string 's' using the POSIX syntax. (Special meanings are carried by unescaped characters.) Returns void if the expression is illegal. |
| str(s:STR): SAME |
|---|
| **** | Returns a regular expression matching exactly the string 's' |
| uppercase: SAME |
|---|
| **** | Returns a regular expression matching 'A', 'B' .. or 'Z' |
| usecase: SAME |
|---|
| **** | Returns a regular expression as self but respecing case. |
| whitespace: SAME |
|---|
| **** | Returns a regular expression matching ' ','\t','\v' and '\n' |
| attr c_regexp: EXT_OB; |
|---|
| **** | Compiled version of the regular expression. |
| attr c_regexp: EXT_OB; |
|---|
| **** | Compiled version of the regular expression. |
| attr c_str: STR; |
|---|
| **** | Regular expression in POSIX syntax. |
| escape(s:STR): STR |
|---|
| **** | Returns a string in which all characters with special meaning are escaped to keep their literal meaning. |
| finalize |
|---|
| **** | The internal buffers of the POSIX regexp may keep some of the buffers reachable, meaning unreachable for GC. |
| attr ignore_case: BOOL; |
|---|
| **** | True, if regular expression does not respect the case. |
| init(s:STR): SAME |
|---|
| init(s:STR,ignorecase:BOOL): SAME |
|---|
| **** | Internal creation routine. |
| normalize(s:STR): STR |
|---|
| **** | Returns a normalized version of 's'. Characters with special meaning in bracket expressions are rearranged to keep literal meaning. |
