Re: [9fans] acme/sam language question
I finally get around to trying this out and (so far) it seems to work. Thank you! You're welcome! Opening the group at the end of the first line has the effect of replacing the empty command and its implied p; see sam's man page under `Miscellany'. This also explains why your lines, without the grouping, had the desired effect when you executed them one by one yourself, but not when executed from a script. Mark.

Re: [9fans] acme/sam language question
What if you specify the address twice like this: /A/+#0;/B/-#0g/CC/ s/CC/DD/g /A/+#0;/B/-#0p That doesn't work if A and B occur more than once in the file or if DD matches A or B. But otherwise, it seems to work for me.

Re: [9fans] acme/sam language question
I write the script like this:
/A/+#0;/B/-#0 {
g/CC/ s/CC/DD/g
}

Well. If I use these commands one by one inside p9p acme
(and probably sam, too), I truly get what I want (and what
you say). The problem appears when I want to run it from
a script like this:
sam -d EOF $1 [2] /dev/null
/A/+#0;/B/-#0
g/CC/ s/CC/DD/g
p
EOF
then you get, since the g is on a seperate line, an extra
output from the line before g. And if you try to join g with
the match like
sam -d EOF $1 [2] /dev/null
/A/+#0;/B/-#0 g/CC/ s/CC/DD/g
p
EOF
then you get no output if CC is not between A and B
(although when it is there, you get what I want).
In neither case I am fully satisfied. :)

Re: [9fans] acme/sam language question
It works for me, but I found another inconsistency. I tried it on p9p and 9vx, both in acme and sam. 9vx acme is different form the others, for some reason. It does print the string between A and B, but prints it with CC and not with DD like sam and like p9p acme. ~Fritz Am 31.10.2013 16:21, schrieb Rudolf Sykora: On 30 October 2013 08:47, Rudolf Sykora rudolf.syk...@gmail.com wrote: On 29 October 2013 17:56, Friedrich Psiorz f.psi...@gmx.de wrote: this should do the trick /A/+#0;/B/-#0 g/CC/ s/CC/DD/g p Thanks for the suggestion, the g construct didn't come to my mind.

Ruda no other suggestions? Thanks Ruda

[9fans] acme/sam language question
Hello, how can I set a dot from after A to before B, then make a global substitution, within thus set dot, of CC to DD and print the resulting text? I.e., if there isn't any CC between A and B, just print what's between A and B, if there is, change it to DD and print all between A and B. I have sth like this /A/+#0;/B/-#0 s/CC/DD/g p which works if there *is* the CC, but not if it is not there; then the s command just resets the dot to an empty set. Thank you Ruda
