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.

Usage

Options

Usage: igcc [options]
Options:
  -h, --help                   show this help and exit.
  -v, --version                show version info and exit.
  -std <standard>              specify c dialect.
  -i, --interactive <boolean>  interactive or not. default: true when there is no "--eval" "--require", false in other cases
  -r, --require <file>         interpret file.
  -e, --eval <...>             evaluate script.
  --read-stdin <boolean>       whether to read from standard input. default: same as interactive
  -Pc <option>                 pass <option> to the c compiler.
  -cc <compiler>               specify c compiler.
  -x <language>                specify the language. permissible languages include: c. default: c

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>.      
    :show               show history.
    ! <command>         excute shell command.

If source-highlight is available on your system, :show uses it to highlight history. Also, if indent is available, it is used to format history.
