| 99 | using some MS magic. I found some useful information on this web page: |
| 100 | http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the |
| 101 | information there, using __declspec(dllexport) without "extern" we have a |
| 102 | definition; with "extern" we have a declaration. The settings here override the |
| 103 | setting in pcre2.h (which is included below); it defines only PCRE2_EXP_DECL, |

Janis Danisevskis | 53e448c | 2016-03-31 13:35:25 +0100 | [diff] [blame] | 599 | character constants like '*' because the compiler would emit their EBCDIC code, |
| 600 | which is different from their ASCII/UTF-8 code. Instead we define macros for |
| 601 | the characters so that they always use the ASCII/UTF-8 code when UTF-8 support |
| 602 | is enabled. When UTF-8 support is not enabled, the definitions use character |
| 603 | literals. Both character and string versions of each character are needed, and |
| 604 | there are some longer strings as well. |
| 605 | |
Janis Danisevskis | 8b979b2 | 2016-08-15 16:09:16 +0100 | [diff] [blame] | 606 | This means that, on EBCDIC platforms, the PCRE2 library can handle either |
Janis Danisevskis | 53e448c | 2016-03-31 13:35:25 +0100 | [diff] [blame] | 607 | EBCDIC, or UTF-8, but not both. To support both in the same compiled library |
| 608 | would need different lookups depending on whether PCRE2_UTF was set or not. |
| 609 | This would make it impossible to use characters in switch/case statements, |
| 610 | which would reduce performance. For a theoretical use (which nobody has asked |
| 611 | for) in a minority area (EBCDIC platforms), this is not sensible. Any |
| 612 | application that did need both could compile two versions of the library, using |
| 613 | macros to give the functions distinct names. */ |

Janis Danisevskis | 53e448c | 2016-03-31 13:35:25 +0100 | [diff] [blame] | 619 | mode. Newline characters are problematic in EBCDIC. Though it has CR and LF |
| 620 | characters, a common practice has been to use its NL (0x15) character as the |
| 621 | line terminator in C-like processing environments. However, sometimes the LF |
| 622 | (0x25) character is used instead, according to this Unicode document: |

Janis Danisevskis | 8b979b2 | 2016-08-15 16:09:16 +0100 | [diff] [blame] | 626 | PCRE2 defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25 |
Janis Danisevskis | 53e448c | 2016-03-31 13:35:25 +0100 | [diff] [blame] | 627 | instead. Whichever is *not* chosen is defined as NEL. |
| 628 | |
| 629 | In both ASCII and EBCDIC environments, CHAR_NL and CHAR_LF are synonyms for the |
