igcc - yet another interactive shell for C development

Overview

igcc is an interactive shell for C development, which can be utilized like REPL (Read-Eval-Print-Loop) for dynamic languages such as Lisp. It would be useful for testing new libraries or learning C language. igcc is basically a thin wrapper around gcc, which invokes the compiler for each lines. Its features and limitations are listed below:

Features

written in less than 700 lines of bash script
line editting with GNU Readline
some useful commands
tab-completion of keywords and commands

Limitations

do not support C preprocessor directives
do not support function definition if use clang
getting user input in C does not work correctly
multiple lines are not allowed as input (use :edit instead)

Requirements

Bourne-again shell (bash) > 4.2
GCC > 4.9 | Clang > 3.8

Installation

Just put the script (igcc) into anywhere included in PATH.

commands

gnu11@(igcc)> :help
    :clear              clear history and reset environment.
    :edit               invoke /usr/bin/nano.
    :exit               exit igcc.
    :help               show this help.
    :include            show added header files.
    :include <header>   add header file.
    :lib                show added shared libraries.
    :lib <library>      add shared library to be linked.
    :load <file>        restore enviroment from <file>.
    :save <file>        save current environment into <file>.
