troll-string-util

This project contains string formatting utilities for embedded applications which use fixed-size strings and where exceptions, run-time type info (RTTI) and dynamic memory allocations are unavailable. It relies on and complements the library etl. It requires C++17 at minimum.

Some useful functionalities for displaying that troll provides include:

• Substituting values into string’s placeholders (format string)
• Console ANSI style code insertions
• Simple tabulations

Utilities here in this project originated as helper modules from my taking of the course “CS 452 - Real-time Programming” at University of Waterloo, in which participants were asked to complete a real-time OS throughout the term.

Usage

Drop the header files or templates you like into your project, or include as your submodule. Note that you need to enable -std=c++17 or similar for them to work.

Please see following pages for the documentation:

• format
• format_scan
• utils

Testing

The CMake files exist primarily for running the test suites. Here are example commands to run them from the command line:

cmake -DBUILD_TESTS=ON -B./build
cmake --build ./build --target troll_util_tests
./build/troll_util_tests
