End of file during parsing?

End of file during parsing?

[Rui Tiago Matos]

I hacked up a bash function [1] to open some files in different
frames. It works great after emacs is running. Otherwise it doesn't:
it opens up emacs but I get:

command-line-1: End of file during parsing

Now, this is very strange because if I use --eval=... from the command
line directly it works as expected. Anyone has an idea about why this
doesn't work?

[1]
emacs () 
{ 
    if [ -z "$DISPLAY" ]; then
        emacs21 $@;
    else
        if [ ! "`/bin/ps -U $UID | grep emacs`" ]; then
            local CMDLINE="--eval=";
            local FILE;
            for FILE in $*;
            do
                if ( grep ^/ <<< $FILE ) || ( grep ^~ <<< $FILE ); then
                    CMDLINE="$CMDLINE(find-file-other-frame \"$FILE\")";
                else
                    CMDLINE="$CMDLINE(find-file-other-frame \"$PWD/$FILE\")";
                fi;
            done;
            if [ "$CMDLINE" != "--eval=" ]; then
                emacs21 $CMDLINE &
            else
                emacs21 &
            fi;
        else
            local CMDLINE="-q";
            local FILE;
            for FILE in $*;
            do
                if ( grep ^/ <<< $FILE ) || ( grep ^~ <<< $FILE ); then
                    CMDLINE="$CMDLINE (find-file-other-frame \"$FILE\")";
                else
                    CMDLINE="$CMDLINE (find-file-other-frame \"$PWD/$FILE\")";
                fi;
            done;
            if [ "$CMDLINE" != "-q" ]; then
                gnudoit $CMDLINE;
            fi;
        fi;
    fi
}

How does bash distinguish between the shell function emacs and the 
binary emacs?

It doesn't, but that is intended :-)

Try changing the command line that invokes emacs in that case to:

emacs21 "$CMDLINE"

The problem is that the shell is splitting the arguments at the spaces 
when you don't quote it.  So the argument that emacs is seeing is:

  --eval=(find-file-other frame

Indeed that works, thanks!

Yet it only solved only part of the problem as I still continued to
have some problems but finally I've come to a solution and I can
finally edit multiple files smoothly :-) FWIW here is the final
version:

emacs () 
{ 
    if [ -z "$DISPLAY" ]; then
        emacs21 "$@";
    else
        if [ ! "`/bin/ps -U $UID | grep emacs`" ]; then
            local CMDLINE="--eval=(defun myfun () ";
            local FILE;
            for FILE in $*;
            do
                if ( grep ^/ <<< $FILE ) || ( grep ^~ <<< $FILE ); then
                    CMDLINE="$CMDLINE(find-file-other-frame \"$FILE\")";
                else
                    CMDLINE="$CMDLINE(find-file-other-frame \"$PWD/$FILE\")";
                fi;
            done;
            if [ $# != 0 ]; then
                emacs21 "$CMDLINE"")" -f myfun &
            else
                emacs21 &
            fi;
        else
            local CMDLINE="-q";
            local FILE;
            for FILE in $*;
            do
                if ( grep ^/ <<< $FILE ) || ( grep ^~ <<< $FILE ); then
                    CMDLINE="$CMDLINE (find-file-other-frame \"$FILE\")";
                else
                    CMDLINE="$CMDLINE (find-file-other-frame \"$PWD/$FILE\")";
                fi;
            done;
            if [ "$CMDLINE" != "-q" ]; then
                gnudoit $CMDLINE;
            fi;
        fi;
    fi
}
