dart-sprintf

Dart implementation of sprintf.

Build Status

ChangeLog

v4.0.0 (2018-07-02)

* **Breaking change** (#13)
  As of dart 2, int types are going to be fixed width, and the width depends on
  implementation (dart2js vs dartvm). Dart started warning about constants that
  are greater than the max int of javascript. To fix that, this patch will limit
  int (when formatted as hex or octal) to the max limit of javascript (2**53 - 1).
  Any int outside of the +-(2**53 -1) range is not guaranteed to format correctly!

v3.0.2 (2017-08-17)

* Fixed bad publish

v3.0.1 (2017-08-17)

* Fixed weak typing which stopped dartdevc from working (#11 thanks @bergwerf)

v3.0.0 (2017-04-20)

* Fixed rounding of floats, again. Bumping major version because it's different from previous behaviour

v2.0.0 (2017-03-23)

* Fixed rounding of floats. Bumping major version, because previous behaviour was to always round down.

v1.1.1 (2016-11-16)

* Updated to use `test` library since `unittest` has been deprecated. 

v1.1.0 (2014-08-21)

* **API change**: Any object with a valid `toString` method can be formatted with `'%s'` (#7)

v1.0.9 (2013-12-15)

* Round numbers when they're truncated. (#6)

v1.0.8 (2013-10-08)

* Remove trailing decimal point if there are no following digits (#6)

v1.0.7 (2013-05-07)

* Update for new dart version

v1.0.6 (2013-04-16)

* Update for new dart version

v1.0.5 (2013-03-25)

* Fixed dependencies example in README (#5)

v1.0.4 (2013-03-21)

* Update for new dart version

* Update for new pubspec format

v1.0.3 (2013-02-12)

* Update for dart M2

v1.0.2 (2013-01-21)

* Pubspec and whitespace fixes

v1.0.0 (2012-10-08)

First release with semver

Getting Started

Add the following to your pubspec.yaml:

dependencies:
  sprintf: "^3.0.0"

then run pub install.

Next, import dart-sprintf:

import 'package:sprintf/sprintf.dart';

Example

import 'package:sprintf/sprintf.dart';

void main() {
	print(sprintf("%04i", [-42]));
	print(sprintf("%s %s", ["Hello", "World"]));
	print(sprintf("%#04x", [10]));
}
-042
Hello World
0x0a

Limitations

  • Negative numbers are wrapped as 64bit ints when formatted as hex or octal.

Differences to C's printf

  • When using fixed point printing of numbers with large exponents, C introduces errors after 20 decimal places. Dart-printf will just print 0s.
