==Application Details==

*Description: 

*Version: readline

*Module: readline/6.3

*Licence: GNU



==Usage Examples==



===Module===

<pre style="background-color: #000000; color: white; border: 2px solid black; font-family: monospace, sans-serif;">

[username@login01 ~]$ module add readline/6.3

</pre>



===Compilation===



''readline'' is a library for use either with a compiled binary that requires it, or it could be required at compilation time also.



The following code is in C and must be linked against the readline library by passing a -lreadline flag to the compiler:



<pre style="background-color: #f5f5dc; color: black; font-family: monospace, sans-serif;">



#include <stdlib.h>

#include <stdio.h>

#include <unistd.h>

#include <readline/readline.h>

#include <readline/history.h>



int main()

{

    char* input, shell_prompt[100];



    // Configure readline to auto-complete paths when the tab key is hit.

    rl_bind_key('\t', rl_complete);



    for(;;) {

        // Create prompt string from user name and current working directory.

        snprintf(shell_prompt, sizeof(shell_prompt), "%s:%s $ ", getenv("USER"), getcwd(NULL, 1024));



        // Display prompt and read input (NB: input must be freed after use)...

        input = readline(shell_prompt);



        // Check for EOF.

        if (!input)

            break;



        // Add input to history.

        add_history(input);



        // Do stuff...



        // Free input.

        free(input);

    }

    return 0;

}



</pre>
