Thank you.
I was pointing out to Benoit that invoking SHELL to run a /bin/echo,
which could seem stupid at first, it is not so stupid because in a
single line you do what gambas would do in three lines. So, it could be
nice to have something similar native in gambas, because in unix
everything is a file. I suspect that this feature would be useful only
in a few situations, so one can well write a subroutine to do that, but
anyway I tried to think at a possible syntax: PRINT/TO, or PRINT/APPEND.
It's funny to invent these things... Writing a subroutine has the
disadvantage that every functionality has the same syntax. Look at what
is clearer:
print "Started" to "/var/log/messages" ' good and clear
syntax
myappend("/var/log/messages", "Started") ' much less readable
or, on the wave of these new stupid languages:
Os.FileSystemUtilities.AppendStringToFile("/var/log/messages",
"Started");
Note that in the myappend() call you don't know, at first, if "Started"
is appended to /var/log/messages, or "/var/log/messages" is appended to
./start. Then you go to the declaration to check this... where is the
declaration in a big project having tenth of sources? I agree that
choosing good names for identifiers is a must, but there could be
something better.
