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

• https://github.com/RobTillaart/PrintCharArray (captures data in a buffer)
• https://github.com/RobTillaart/PrintSize. (captures data in a String)

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;
