Q: Does SLRE support Unicode or international characters?

SLRE focuses on basic ASCII-based regex syntax and may not fully support Unicode. For applications requiring international character handling, a more comprehensive library like ICU or PCRE is recommended.

Q: What's the memory usage of SLRE in an IoT device?

SLRE typically uses under 10KB when compiled, making it suitable for IoT devices with limited RAM and flash. However, performance on large strings might be slower due to its lightweight design.

Q: How can I use SLRE commercially without GPL restrictions?

To use SLRE commercially without GPL obligations, purchase a commercial license from Cesanta. The README provides contact information for pricing, and they offer royalty-free licenses for flexible deployment.

Q: Are there examples of SLRE parsing network protocols?

Yes, SLRE is well-suited for parsing lightweight network protocols in C/C++. Its portability and minimal footprint make it a good choice for embedded network applications, though examples might be limited in the documentation.

Question 1

How do I add SLRE to my C project for pattern matching?

Accepted Answer

Integrate SLRE by including its source files in your project and using the simple API functions like slre_match(). Check the documentation at docs.cesanta.com/slre for specific examples and setup instructions.

Question 2

SLRE vs PCRE: which is better for embedded systems?

Accepted Answer

SLRE is superior for memory-constrained embedded systems due to its small footprint (<10KB), while PCRE offers more features but at a larger size. Choose based on whether memory or advanced regex capabilities are your priority.
