Here's a script to automate the launch of Win and DOS demos in Linux.

category: code [glöplog]

Decided to write a Bash script to make things faster.
It only takes 1 argument, the demo archive or the existing demo directory.
It's menu based so no command line options.

example: thisscript.sh /mnt/dvd/demoname.zip

Code:


#!/bin/bash

FileReader=less
FileEditor=vim

exepath=""
demopath=""
exename=""
workdir=""

separator="=================== "

function fnError
{
    echo ERROR $@
    echo
    echo "Usage: startdemo.sh <demo archive or directory>"
}

function fnSplitPath
{
    exename=$(basename "$exepath")
    workdir=$(echo "$exepath" | sed -e 's,/[^/]\+$,,g')
    #echo -e "executable="$exename \\n"working directory="$workdir \\n
}

function fnWineMenu
{
    #got Wine?
    wine --version &>/dev/null
    if [ $? -ne 0 ]; then
        echo "But you don't have Wine :("
        return
    fi

    cd "$workdir"

    #show menu
    local isDone=0
    local items=('Configure' 'Toggle explorer use' 'Launch' 'Cancel')
    local options=""

    while [ $isDone -eq 0 ]; do
        echo -e ${separator}Wine menu
        if [ -z "$options" ]; then
            echo "explorer [OFF]"
        else
            echo "explorer [ON]"
        fi

Updated the fnDosMenu function. Creating a config file for each dos demo was a waste. Now it's the same file for all.

Code:


function fnDosMenu
{
    #got DOSBox?
    dosbox --version &>/dev/null
    if [ $? -ne 0 ]; then
        echo "But you don't have DOSBox :("
        return
    fi

    #use default config as a template
    local template=$(dosbox -printconf)

    #create dosbox config file if it doesn't exist
    local dosboxconf=~/.dosbox/demos_dosbox.conf
    cd "$workdir"
    if [ ! -f "$dosboxconf" ]; then
        if [ ! -f "$template" ]; then
            echo "ERROR no dosbox template!"
            return
        fi
        cp "$template" "$dosboxconf"

        echo Created "$dosboxconf"
    fi

    #show menu
    local isDone=0
    local items=('Configure' 'Launch' 'Cancel')
    while [ $isDone -eq 0 ]; do
        echo -e ${separator}DOSBox menu
        select i in "${items[@]}"; do
            #configure dosbox
            if [ "$i" = "${items[0]}" ]; then
                $FileEditor "$dosboxconf"

            #launch
            elif [ "$i" = "${items[1]}" ]; then
                dosbox -conf "$dosboxconf" -noautoexec "$exename"

            #done
            else
                isDone=1
            fi
            break
        done
    done
}

Nice work. Don't use DOSBox on Linux though :/
Sometimes DOSBox need specific options for the demo to run (no XMS, GUS, whatnot), so a specific configuration for every demo might be necessary.

Having a fast machine with this and a DVD-style menu as a frontend would be sweet. DOS demoplayer... ;)
