Top Forums Shell Programming and Scripting Another IFS post, [ bourne SH only ] ? Post 302375980 by gcampton on Monday 30th of November 2009 09:30:42 AM

I'm thinking that maybe I need to just stick the arguments into a temp $VAR or file
and then convert back to OLDIFS at bottom of loop and then execute function using the var/file as arguments, convert back to NEWIFS...

But, not quite sure if this would work seems a bit problematic to me.

Code:
OLDIFS=$IFS
IFS=":\n"

tr '[:lower:]' '[:upper:]' < $opfile |
while read cmd arg1 arg2 arg3 arg4
do
    case $cmd in
        ADD) cmdadd=`add $arg1 $arg2 $arg3 $arg4`
            ;;
        DELETE) cmddelete=`delete $arg1 $arg2 $arg3`
           ;;
        ETC) etc etc
            ;;
        *) echo "invalid"
    esac
    IFS=$OLDIFS
    #somehow execute the variable or file... maybe another case?
    IFS=":\n"
done

NAME
shevek::ristring - shevek::ristring is identical to shevek::istring, but it uses std::string instead of Glib::ustring. SYNOPSIS
#include <iostring.hh> Public Member Functions ristring () Create a new istring with no data. ristring (std::string const &str) Create a new istring with data. void init (std::string const &str) Set new data to an existing istring. void push () Push the current position to the stack so it can be restored later. int pop (bool keep=false) Pop the last pushed position from the stack. void reset () Set the current position to 0, but don't change the stack. std::string rest () const Get remaining string. void skip (std::string::size_type p) Skip some characters. bool operator() (std::string const &format) Read a constant string from the input. template<typename T1 > bool operator() (std::string const &format, T1 &arg1) Read a string containing one argument from the input. template<typename T1 , typename T2 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2) Read a string containing two arguments from the input. template<typename T1 , typename T2 , typename T3 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2, T3 &arg3) Read a string containing three arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4) Read a string containing four arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5) Read a string containing five arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 , typename T6 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5, T6 &arg6) Read a string containing six arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 , typename T6 , typename T7 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5, T6 &arg6, T7 &arg7) Read a string containing seven arguments from the input. template<typename T1 , typename T2 , typename T3 , typename T4 , typename T5 , typename T6 , typename T7 , typename T8 > bool operator() (std::string const &format, T1 &arg1, T2 &arg2, T3 &arg3, T4 &arg4, T5 &arg5, T6 &arg6, T7 &arg7, T8 &arg8) Read a string containing eight arguments from the input. Static Public Member Functions template<typename T > static T direct (std::string const &data, std::string const &format, T def=T()) Read a variable from given data and return it. Detailed Description shevek::ristring is identical to shevek::istring, but it uses std::string instead of Glib::ustring. Member Function Documentation template<typename T > static T shevek::ristring::direct (std::string const &data, std::string const &format, Tdef = T ()) [inline, static] Read a variable from given data and return it. This allows using a shevek::istring in an expression without the need to create a new variable for it. If the input doesn't match the format, def is returned. int shevek::ristring::pop (boolkeep = false) Pop the last pushed position from the stack. If keep is true or not given, the current position is restored to the last position. If it is false, the current position is not changed.
