PrintSize

Arduino library to determine the length of print statements.

Description

PrintSize is a minimal library to determine the length of a variable when printed. This includes printing of floats, integers in decimal or hex notation.

Works for print(), println() and if supported printf() e.g. ESP32.

Finally since 0.2.0 it has a total counter to add up the characters "printed" since the last reset() call. (see example)

This library is related to

Operational

Example shows the right alignment of 10 random numbers.

Example shows (elementary) line fitting.

Applications

Can be used to calculate the needed space.

  • to properly do a right alignment e.g. for numbers or variable text.
  • do left alignment and overwrite previous output with just enough spaces.
  • centring of numbers.
  • see if output will fit into a line / display.
  • see if a string fits in EEPROM or any other storage medium.
  • see if a string fits in a communication buffer.

Future

  • add examples
  • add a function to handle tab char correctly e.g. could add more than one char. Interferes with the write(str, length).
    • setTabSize(2,4,6, 8...);
    • getTabSize();
    • uint8_t _tabSize = 4;
