- NoPrintf - try to avoid printf without loosing formatted strings + without fiddling with << operators.
- Have engineers formatted units like mV, kWh auto selected from field size.
- Select language from a table.
- Robustness by test driven development and unit test integration in local runs and github actions.
Inspiration came from 30 years bad experience with printf, good things seen from Qt and Boost. And last but not least from an i18n discussion on Ahoy DTU Discord, where we ended up in simple i18n allows "no printf", because of grammar and argument order.
Aside of this, I always wanted to have an "fixed format engineers formatting" for numbers, like
1.345 mW * 100
134.5 mW * 100
13.45 W * 100
1.345 kW * 100
134.5 kW * 100
13.45 MW
and so on ...
- working for strings and const char
- working for relevant integers
- conditionally compile with float
- benchmark for low copy mem footprint & speed
- metric prefixes "fpnµm kMGTP" auto select the way, always having 1 to 3 digits in front of the dot, on grow or shrink: take next 10^3 prefix.
- ESP8266 and ESP32 optimized
- translation table for latin-1 codepage languages 1st.
- verification of UTF8, mbcs or wstring while keeping gnu++11 compatibility (PlatformIO default)
This does not replace the Issue Tracker from github. Or ... indeed it recently does ;-)
