Does anyone know if it is possible to "pipe" output such as the
contents of a file to another program? What I am doing is that I
have a REPL that reads in code. What I want to be able to do is
make changes to code in BBEdit, and then send it into a running
instance of my environment, so that, for example, I can make
changes to the code and have those changes take effect in the
running instance without having to reload and re-execute
everything. Is this possible?
What is REPL?
I guess that I should have explained a bit better what I was aiming
for. REPL stands for “Read Eval Print Loop” and is something like a
command line interface that allows interactive running of programs and
functions. Specifically, this is for a Scheme system.
Anyway, I doubt that you can get BBEdit to reload code on behalf of
another program. But it's easy enough to write a script (Perl,
AppleScript, etc) that can tell the other program that it's time to
re-read the code file. I do something similar with apache/mod_perl.
After I make code changes I hit a command key which triggers a
script (within BBEdit) to tell apache to reload.
Aaah, see, I would need to actually pipe the file or a selection of
the file into the standard input of a currently running instance of
the program.
As for how to have code changes take effect without reloading; that
will depend on the program that is running the code. Does it support
live code changes?
Live code changes come about as the result of re-evaluating code
passed to the environment, in the same way that you would type new
commands into the command line.
