Hello,
I'm porting some personal perl5 scripts to Raku, and one of those
scripts is using Inline::C.
The inline::c code would contain a function with the signature:
AV* encode(unsigned char* data, size_t data_size)
Description of the parameters on the original perl script:
data -> binary
Hi David,
the first thing that catches my eye is that your struct and the class
have the members switched around, so you're already almost guaranteed to
read a bogus pointer when trying to get the data.
Also, please note that returning structs directly, or passing structs
directly, as arguments
Thanks for the help.

I did those two changes:
"""
EncodedData* ed = malloc(sizeof(EncodedData));
ed->data
The ｢@i｣ is defined within the ｢BEGIN｣ block, so it is scoped to the
｢BEGIN｣ block.
If you didn't want that, don't use a *block* with ｢BEGIN｣.
BEGIN my @i;
Also you wrote the ｢if｣ wrong.
There shouldn't be a ｢;｣ before the ｢if｣.
You also don't need to use ｢$_ ~~ ｣ with ｢/^WARN/｣ as that

You're returning a pointer to encbuffer -- make sure the storage for
that is kept around
somewhere. If it is passed in from Raku,
Hi,
I am trying to write an one-liner to go through all lines in a logfile and
look for an certain key word, store the line and sort them before printing
them out.
My approach was:
raku -ne "BEGIN {my @i }; @i.push($_); if $_ ~~ /^WARN/; END { @i.sort.say
}"
That does not work because @i does

I haven't tried all of this, but the first thing that leaps out is
that repr('CStruct') is
not a struct -- it
ooh neat! I didn't know. Indeed this works. Thanks Sean!
raku -ne'push my @i: $_ if .starts-with: q[WARN]; END .say for @i'
sample.log

Ooops forgot the sort... let's golf with the hyper-operator again...
raku -ne'push my @i: $_ if .starts-with: q[WARN]; END @i.sort>>.say'

Maybe?
perl6 -e 'lines() ==> grep /^WARN/ ==> sort() ==> join("\n") ==> say();'
HTH, Bill.

Thanks for the information!
Have a great weekend!

Or alternately the main body of the loop can be written:
(my @i).push($_) if /^WARN/;
Or even:
push my @i: $_ if /^WARN/;

There is an old open bug report about this:
I like this formulation Fernando posted (removed a set of parens not needed
with method calls)
raku -e'lines.grep(/^WARN/).sort».say' sample.log
It is clean, all left-to-right, and doesn't use "map" for its side-effects
only.
Putting the feed operator back in where it would work–have to keep
I also noticed that although my data string is defined as
CArray[uint8], when i loop through the array, the values are signed
ints:
say $_ for $ed.data[0..10];
output:
-98
-110
-109
-99
74
-109
-99
74
-105
-93
74
Is it possible to not "sign" them?

raku -e'.say for lines() ==> grep(/^WARN/) ==> sort' sample.log
is not very satisfying because for the "for" which breaks the flow.
OTOH this
raku -e'lines().grep(/^WARN/).sort».say' sample.log
doesn't use the feed operator and this
raku -e'lines() ==> grep(/^WARN/) ==> sort() ==> say()'

and the reduce call can be written more compactly: reduce({"$^a\n$^b"})
