Can I use standard Ruby Gems with this skill?

No, PicoRuby does not support Bundler or the standard Gem ecosystem due to the minimal runtime environment of the ESP32.

Does PicoRuby support regular expressions?

No, Regex is unavailable in PicoRuby; developers should use basic string matching methods or manual parsing instead.

What standard library methods are safe to use?

Basic methods for Array, Hash, String, and Time are available, though some specific methods like #each_with_index should be avoided in tight loops.

What is the primary memory limit for PicoRuby on ESP32?

The total heap is strictly limited to 520KB, which requires developers to use fixed-size arrays and avoid repeated string concatenation.

How does multi-threading work in PicoRuby?

PicoRuby uses a single-threaded runtime. Threads, Fibers, and complex enumerators are not supported to keep the system lightweight.

개발자 도구

Enforces memory limits and standard library constraints for PicoRuby applications running on ESP32 microcontrollers.

소개

This skill provides essential guardrails for developing Ruby applications on resource-constrained hardware using the PicoRuby runtime. It guides developers through the specific limitations of the R2P2-ESP32 environment, including the strict 520KB heap limit, the absence of regular expressions and threads, and the architectural differences between PicoRuby and CRuby. By incorporating these constraints directly into the coding process, the skill helps prevent runtime failures and ensures efficient memory management and performance for embedded Ruby projects.
