This section documents Fun's optional, build-time selectable extensions. Each page covers:
|
|
|
|
- How to enable the extension via CMake option (FUN_WITH_*)
|
|
- Build requirements and detection notes
|
|
- Available opcodes and/or helper functions
|
|
- Minimal usage examples and links to example scripts
|
|
|
|
## Extensions:
|
|
|
|
- [cURL (libcurl)](./curl/)
|
|
- [INI (iniparser)](./ini/)
|
|
- [JSON (json-c)](./json/)
|
|
- [libxml2 (XML)](./xml2/)
|
|
- [SQLite](./sqlite/)
|
|
- [PCRE2 (Perl-compatible regex)](./pcre2/)
|
|
- [PC/SC (Smart cards)](./pcsc/)
|
|
- [OpenSSL](./openssl/)
|
|
- [kcgi](./kcgi/)
|
|
|
|
## Notes:
|
|
|
|
- These integrations are optional; the VM compiles without them.
|
|
- When disabled, related builtins usually return empty strings/neutral values rather than fail hard, mirroring existing optionality patterns.
