[9fans] sam and 'here documents' on Unix [WAS: Re: Making multiple changes to dot using sam -d]

[Mart Zirnask]

A related question:
9front sam has the ^ command, which makes it easy to apply multiple
sam commands to the dot from a script, e.g:

#!/bin/rc
cat << END
,x/red/ c/blue/
,x/yellow/ c/green/
END

How does one accomplish this in oldschool Unix sam -d without the ^
command, and also without using ssam?

'Here dcuments' work, because the following works fine on my shell
(Busybox sh, not rc):

$ sam -d file.txt << END
,x/red/ c/blue/
,x/yellow/ c/green/
w
q
END

However, piping dot to that script from within sam -d (using the |
command) ends up with:
sh: script.sh: not found
?warning: exit status not 0

...and also an empty (deleted) sam buffer.

Replacing 'cat' with other options, e.g. 'sam -d "$*"', eventually
gave a "broken pipe" message. And, again, in all cases, an empty
buffer.

So, no ^ command, no ssam, but want to use substitutions from 'here
documents' -- where am I going wrong?
Many thanks,
Mart

hmm, interesting. ^ is indeed very useful;
making it work in sam -d is probably the
correct thing to do but here's a quick hack.
(9front specific, tho you can probably figure
out another way to pretend you typed.)

Sorry for the late reply -- great hint, thanks very much.

In a perfect world, I would need a solution that also works on Windows
(with the ported unix/p9 tools), but I'll probably build the
sam9f-unix port by iru- [1] for now.

Btw, can anybody point me to the initial ^ and/or _ command patch?
In which 9front release were they added?

Thanks and best,
Mart
