[Larceny-users] Evaluate <expr> at startup does not work for import

[Marijn Schouten (hkBst)]

Hi,

I noticed that it doesn't seem to work when you try to import at startup.


$ larceny -err5rs -- -e "(import (rnrs))"
Larceny v0.97a4 (alpha test) (May 10 2009 12:38:12, precise:Linux:unified)


Error: Undefined global variable "rnrs".
Entering debugger; type "?" for help.

(import (rnrs))

Autoloading (rnrs)
Autoloading (rnrs enums)
Autoloading (rnrs lists)
Autoloading (rnrs syntax-case)
Autoloading (rnrs conditions)
Autoloading (err5rs records procedural)

Autoloading (rnrs hashtables)
Autoloading (rnrs arithmetic bitwise)
Autoloading (rnrs programs)
Autoloading (rnrs files)

Autoloading (rnrs records syntactic)
Autoloading (rnrs records procedural)
Autoloading (rnrs control)
Autoloading (rnrs sorting)
Autoloading (rnrs bytevectors)
Autoloading (rnrs unicode)
I would like to start larceny in a way that loads syntax-case before loading
whatever file I want to run (also in the same command). Is that possible?

Thanks,

Marijn

PS My svn troubles were caused by using neon-0.28.4. I've downgraded to
neon-0.28.3 and now svn works fine again.

I noticed that it doesn't seem to work when you try to import at startup.

In Larceny, all code that is evaluated using the -e
command-line option must be written in R5 Scheme.
That allows you to load R5RS code at startup, even
if the mode is ERR5RS.

I suppose we could add an -eERR5RS command-line option,
but right now we're trying to figure out how to reduce
the number of command-line options we have to support.

In R6RS mode, of course, the -e command-line option isn't
interpreted at all.

I don't think that's feasible in Larceny's ERR5RS mode.
On the other hand, it sounds as though you may be trying
to run something as a batch program, in which case R6RS
mode might work for you.

Thank you for following up on that.
