Fmt

An experimental Oberon-7 module to provide format functions for INTEGER and REAL values. It is inspired by Karl Landström's OBNC oberon compiler and his extension library.

Installation

Prerequisite

This repository assumes you have installed Karl Landström's OBNC compiler v0.16.1 or better. It assumes you have a working C tool chain configured (e.g. clang, gcc, make). If you can compile and install Karl's extenions modules obnc-libext-0.7.0.tar.gz then you should be able to install this package.

Setup

The installation process was inspired by Karl's scripts for https://miasap.se/obnc/downloads/obnc-libext_0.7.0.tar.gz and mirrors that process and most of those assumptions.

The basic process is

1. build
2. test
3. install

In the shell I do

    ./build.bash && ./test.bash && ./install.bash

By default modules are installed relative to your home directory but if you want to install them in a system directory for other users (e.g. /usr/local) then try

    ./build.bash && ./test.bash && ./install.bash --prefix=/usr/local

Usage

This module is intended to be used with other Obeorn-7 programs and module. This is an example of retrieving the Unix epoch.

    MODULE Fmt;
      IMPORT Out;
    VAR
      i : INTEGER;
      r : REAL;
      fmt : ARRAY 24 OF CHAR;
      dest : ARRAY 128 OF CHAR;

    BEGIN
      i := 42;
      Fmt.Int(i, "%4d", dest);
      Out.String("Formatted i: ");Out.String(dest);Out.Ln;
      r := 42.0;
      Fmt.Real(i, "%4.2f", dest);
      Out.String("Formatted r: ");Out.String(dest);Out.Ln;
    END Fmt.

Acknowledgments

This project would not be possible with Oberon so a giant thank you goes to Niklaus Wirth, Jürg Gutknecht, Martin Reiser, Paul Reed et el.

A big thanks also goes to Karl Landström for creating OBNC a very nice open source Oberon-7 compiler.
