• FPC snippet.

    From j b l@1:154/700 to All on Thu Jan 26 19:50:19 2017
    Hi,

    I have some FPC code, that isn't working the way it should.

    if FileExists(fn+'.PK2') then shell('/usr/bin/mv '+fn+'.PK2 '+fn+'.MIX');

    It works like this. It checks for the existence of, say, SOMEBOARD.PK2, and if that file exists, it moves it to SOMEBOARD.MIX. The problem is that it isn't moving the file(s).

    Does this look right?

    Thanks,

    Is there any reason you're not wanting to use the Rename procedure that's
    part of the fpc system library?

    www.freepascal.org/docs-html/rtl/system/rename.html

    One problem with your code is that it would depend on a *nix style operating system, and that the 'mv' command is available at your specified path. Obviously that makes your code less portable. That might not matter, but if it's potentially a concern it's worth noting.

    Because it simply does not work. In fact, everything i've tried involving the "fn" variable does not work. I'm tearing my hair out over this. I simply cannot figure it out. If someone could take a look at http://www.catch22bbs.com/msgpack.pas , i'd appreciate it. I'm still a newbie with (Free) Pascal, so there are obviously some things that I would miss. Sudden Death offered his help, but it ended up not working as well. :(

    Was this a typo? Or should the first instance of "fn" have a "+" before it as well?

    You're showing you are not a programmer! ;)

    + Is the operator to concatenate two strings together. So you are not puting it
    just in front of a string or string variable, but between them...

    Bye, Wilfred.

    There's usually a lot more spacing in what I've seen in the past, so.. oh well.
    I tried.

    Nah. The first "+" is usually appended on to something that "continues" the argument. If that makes sense. The first argument usually doesn't have it.

    no, not a typo... read the ""properly formatted""* routine like this


    if FileExists(fn+'.PK2') then
    shell('/usr/bin/mv ' + fn + '.PK2 ' + fn + '.MIX');


    the pluses, in this case, are appending strings together...

    i'd be interested in what the variable "fn" contains... i'd also be concerned about that forced caps stuff with ".PK2" which may be lower case on some file systems which may be case sensitive...
