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)

Interface

#include "PrintSize.h"
  • PrintSize() Constructor
  • size_t write(uint8_t c) core. Note: gives a warning unused parameter.
  • size_t write(uint8_t * str, uint8_t length) Note: gives a warning unused parameter.
  • void reset() reset the total counter.
  • uint32_t total() total bytes "printed".

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

Must

Should

  • 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;

Could

  • PRINTSIZE_LIB_VERSION ?
