HS logic: basic question about file management

[Warichet]

Hi,

I've a basic question about file management.
What would be the HS equivalent of the classic loop:
while not EOF
read line
do something
end while
I understand, if the data is < 10K, no problem, it fits at once in a single 14Byte var, and from then on, one can work on it with memory var.
But if I want to work on the HS Login List (32K text, 98K html), how can I exploit the file?
If there are 500 lines in the file, I'm going to write 500 modules ? No I guess

As an aside: is it possible to call an "external" application ? and eventually re-import the data into the HS ?

Thank you in advance for your patience with a newbie
Raymond



PS: sorry if the topic has alreaddy been discussed, but can't find it in the old forum (not sure about the keywords for search)

This is not true! The webpage query reads up to 500.000 bytes = ~ 488 kBytes!
Only 14-byte Textobjects can hold 10k only. This means that you are able to query a webpage with 98 k HTML but if you try to put more than 10k into a single 14-byte Textobject you will loose some data.

Thank you for putting me right

I see no answer here, so I conclude it is not possible
It is said that the HS logic is Python. OK, but Python does support file management

is it possible to call an "external" application ? and eventually re-import the data into the HS ?

Any hint about this ?

No, actually not possible via HS-Logic

[MatthiasS]

The only way, and so I did with hs2wav and wetter2hs, is to send an IP telegram to your external application, make some calculations and deliver the result back the same way.

I dont want to fight another Windows against Linux war. But with misterhouse it would be possible, no doubt about.

MH uses perl and you could (as an example) be able to read a file containing caller ids from one file

01234567 Peter
987654321 Anne
...

Read that with a view lines of perl

my %cid2name;
open(<CID>,"/where/ever/the/file/is") die "could not open file!";
while($line = <CID>) {
  ($id, $name) = split(/ /,$line);
  $cid2name[$id] = $name;
}

And than use this data with a line like that

print_log sprintf("%s is calling from %s", $cid2name[$cid], $cid);

or react on the callername like

if ($cid2name[$cid] eq "Peter") {
  set $Garagedoor OPEN;
}

@Matthias
Thank you, I'll give it a try, but, hum, it's not so trivial. I guess you talk about application to application programming, via ports ?

@RaK
I'm pretty convinced about Perl, but when all you have got is Python....
"quand on n'a pas ce qu'on aime,
faut aimer ce qu'on a"
Loosely translated as:
"when you don't have what you love,
love what you have".
Tell this to your wife tonight, and tell us the reaction

Don't confound Python with the HS function files (.hsl). Basically the HS only allows you to use python expressions to compute your figures. It does simply not allow you to use full python language. So you are limitted by the hsl syntax, not by Python.

Not to start a "religious" discussion, but python is more or less replacing perl nowadays, so don't believe that Python would be weaker then Perl

Cheers,
Gaston

And don't believe, that todays limited access to python inside hs will be limited the same way forever!

OK, that's something I recently discovered (the hard way). It's not obvious when you read about the HS and it's possibilities. Anyway, I'm convinced I made the right choice, just a bit frustrated by an annoying limitation.

And don't believe, that todays limited access to python inside hs will be limited the same way forever!

Oh gosh, if this could be true
I'm sure I'll will be flamed, knocked ans sacked (in that sequence, please ) for this, but...mmm. I found this Python logic a crummy way of programming. Of course, the big plus is the grahic part of the logic editor , but I would happily give it up in favour of a standard scripting language. I know, we are not really on "computers" but a standard scripting tool would benefit to everyone (except maybe to the fellows which have invested so much of their time in the currently available HS libraries)

Best regards

Raymond,

please be so kind (in this case), to wait for the release of the release after the soon coming up!
First, it will be a overwhelming one, and be sure, that the beta.testers are pushing hard to realize new features in addition to the coming ones!

[Warichet]

please be so kind to wait for the release

Patience is not in my best skill .... but ... OK ...

it will be a overwhelming one
