stdc 1.0.4

A minimal-abstraction Standard C Library implementation for Dart. Designed for C programmers to seamlessly use familiar functions like stdc.printf or stdc.sin.

1.0.4

• Massive Systems-Level Feature Expansion: Added support for three core C standard headers simultaneously (<stdlib.h>, <stdio.h>, <time.h>), significantly expanding the library's utility for C programmers seeking a zero-abstraction environment in Dart.
• <stdlib.h> Addition: Implemented essential standard library utilities mapping directly to native-equivalent concepts:
  • String conversions: atoi, atol, atof.
  • Pseudo-random number generation: rand, srand.
  • Integer arithmetic: abs, labs, llabs.
  • Searching and sorting: qsort, bsearch (designed to use pure Dart's optimized algorithms while exposing the familiar C signatures with comparators).
• <stdio.h> Addition: Brought raw, authentic C-style I/O to Dart using direct dart:io hooks where appropriate:
  • Formatted I/O: Added a lightweight, zero-dependency sprintf and printf implementation that mimics C's format specifiers (%d, %s, %f, %x, etc.) without bloating the library.
  • Character and String Output: puts, putchar.
  • Standard Input: getchar, gets.
• <time.h> Addition: Implemented low-level time tracking utilities mapping to system ticks and epochs:
  • Core timing: time, clock.
  • Utility functions: difftime, ctime.

1.0.3

• <string.h> Addition: Implemented standard C string manipulation functions (strlen, strcmp, strcpy, strcat, strstr, etc.). Mutating functions like strcpy and strcat have been adapted to return a new string, adhering to Dart's immutable String nature while maintaining familiar C naming conventions.

1.0.2

• <ctype.h> Addition: Implemented standard character classification and conversion functions (isalpha, isdigit, toupper, tolower, etc.). Designed to accept String inputs for ergonomic use in Dart while maintaining native performance.

1.0.1

• Version Reset: Reset versioning to 0.1.0 to properly track early development of the library before a stable 1.0.0 release.
• Initial Architecture Setup: Implemented the core Stdc extension architecture, allowing a unified stdc namespace across different headers.
• <math.h> Implemented: Added comprehensive support for C standard math functions (sin, cos, sqrt, pow, ceil, floor, abs, fabs, etc.) mapped to Dart's highly optimized dart:math.
• Examples & Tests: Created example/stdc_example.dart and test/stdc_test.dart.
• Documentation: Added comprehensive API dartdoc comments to all functions, classes, and constants.

1.0.0

• Initial placeholder version from Dart template creation.
