nErVe hello every one.. 00:42
i was wndering what regular expression would define values like these 00:43
:0.210867130540167
i have them in a file and i dont need them as such
so want ot delete them
skids perl5?
nErVe yes
OHH..
i m sorry 00:44
skids \:\d+\.\d+ but yeah try #perl
nErVe i forgot this was perl 6
hey skids thanks for the help 00:49
skids np
nErVe would the regex you gave delete the value
skids s/ \:\d+\.\d+//g would, assuming you want the colon gone too.
erm, extra space in there. 00:50
nErVe i was suggested =~ /:\d+\.\d+/
byt ~perl
#perl i mean
skids Maybe, perl6 escapes all literal metas so I've been getting into that habit.
nErVe so the exact regex to delete the values would be..?? 00:51
s/ \:\d+\.\d+//g as you said ..??
right..I m sorry I am newbie at regex 00:52
skids s/:\d+\.\d+//g (minus the accidental space and the exra \)
00:58 M_o_C joined
buu nErVe: Please note that the s/// operator has nothing to do with the actual regex 01:01

nErVe i was reading more about regex 01:15
from what i understand in could stand for substitution
is that right buu
01:15 icwiener_ left 01:18 DemoFreak left 01:22 Whiteknight left
nErVe just a last bit 01:22
if i was to delete/substitute numbers the regex would be ? 01:23
last nErVe: If you just want to delete the numbers (without determining what they are) the s///g skids wrote should do the trick, I believe. 01:24
nErVe well this time is different i want o delete Node21 and values like them
last ..any suggestions.? 01:25
last nErVe: not sure what you mean by Node21? 01:26
nErVe well i want to delete "NODE21" similarly "NODE22" 01:27
buu NODE\d+
Maybe.
last nErVe, NODE\d+ would be NODE followed by one or more digits. Does that sound right? 01:28
deleting it would be s/NODE\d+//g
nErVe its does not delete.. 01:30
scsys.co.uk:8002/30044 01:32
last you there buddy..? 01:34
last sorry, was working in another window 01:35
nErVe ne ways i was wonderin if you could find out the error in my script 01:36
last actually, your script works great for me. 01:37
the NODE digits are deleted. 01:38
well, NODE and the digits.
Is that not happening for you?
(I'll be a minute, I've got to calm a baby here.)
nErVe welli want ot delte the node21 both
i mean the digit and the word node 01:39
also it doesnt not delete either
ne clue wat i cld be doing wrong 01:40
last is it lower case or upper case? 01:46
the way you've got it will only delete all upper case "NODE" 01:47
01:48 athomason left
nErVe oh so i have to make the smaller case in the regex ..?? 01:48
last it is case sensitive, so it will match the case you use in the regex. 01:49
01:49 sri_kraih left 01:50 sri_kraih joined
last if you want it to be case insensitive, you need to add the letter i after the g, so it's $line =~ s/NODE\d+//gi; 01:50
nErVe hey thanks a lot that is a new trick I learnt 01:51
man life as a life science student is horrible..
hehe..
but its nice to have people like yourself around
last glad I could help. 01:52
01:52 wolverian left
nErVe btw just one more thing if you would not mind...how would i open edit and save the same file again 01:52
i mean i have open the file
now i ve deleted the things i dont want
now i want to save it
01:53 mkfort joined
last I usually move the existing file to a backup, then copy it with the changes to a new file with the original file name. 01:53
give me a sec... 01:54
nErVe well thats not needed in my case because currently im working on fake data sets the actual file will be much larger 01:55
last gist.github.com/132998 is the way I do it. 01:57
(I'm sure there are better ways to write that code, that's just the script I've had sitting around for the last ten years.)
Doing it in place is more complicated, I'd suggest going with the backup unless you don't have the disc space for it. 01:58
01:59 molaf_xx joined
nErVe could you please explain the code.. 01:59
last huh, something went wrong with the gist? one sec. 02:01
Try it again, first try had an embedded ASCII 0 character that messed up github. 02:04
nErVe scsys.co.uk:8002/30045 do you think this will work..?? 02:06
last You need to move the second open statement up out of the loop.
everything else looks right. 02:07
skids For Perl5 there are commandline options for that.
last does require loading the entire file into memory to work, but as long as you've got enough memory to do that...
nErVe well i have a 3 gb ram 02:08
but i will running it on power mac at the uni
its has 8gb..
the max i ve ever seen..
i got syntax error at 8 and 16 02:09
skids e.g. perl -pne -i.bak 's/:\d+\.\d+//g'
nErVe with the open statement you told me to move 02:10
last open(TFILE,">$treeFile"); # needs quotes and semicolon
nErVe i have given them
last skids: I always forgot about the command line options. That's beautiful. 02:11
nErVe ohh i forgot to save the file.. 02:12
i ran it now it gives me..Use of uninitialized value $_ in print at ./notung_file_parser.pl line 15.
last print TFILE $line; 02:13
because you are using $line as the variable in the loop instead of $_ 02:14
02:15 M_o_C left, molaf_x left
nErVe Scalar found where operator expected at ./notung_file_parser.pl line 17, near "TFILE $line" 02:18
(Do you need to predeclare TFILE?)
syntax error at ./notung_file_parser.pl line 17, near "TFILE $line"
Global symbol "$line" requires explicit package name at ./notung_file_parser.pl line 17.
go it.. 02:19
got it..i think he errot..
error
i had used the $line at close 02:20
btw can you help me modify you code the one u posted to work with one i have written..?? 02:21
last Just replace the line # insert your s/// code here!! with the two s/// expressions you use. You don't need the $line =~ bits, because you will be working directly with $_ in my code. 02:24
Need to get my nose down into some ugly C++ code now.

TimToady if you want the whole series

masak no, there's no context in the backlog to clarify Matt-W's "living in the future" remark. I'm kinda hoping he was referring to my latest blog post. 11:51
lichtkind Su-Shee: thanks but the links are know but the docs page is currently in bad state im currently reformating, im aware that what i do is only one of many tutorials but i had these links look: www.perlfoundation.org/perl6/index....inks_table 12:04
Su-Shee: are you more interested in perl 6 docs? 12:09
Su-Shee lichtkind: interested? I'm _so_ waiting for a real book... so yeah, I'm really interested. :) 12:11
lichtkind: I just added them because they're rather good right now and there's isn't too much waving the perl6 flag right now. :)
lichtkind Su-Shee: how you mean that? 12:12
Su-Shee lichtkind: it's not that we've got a perl6 hype on our hands right now so I smuggle one in with useful links. ;) 12:13
lichtkind Su-Shee: hype sucks, only lamer wnat to surf on a hype wave :)
i should write LAMORZZ
Su-Shee lichtkind: a little more recognition can't hurt. 12:14
masak lichtkind: no, it's not only lamers that would recognize Perl 6 through a hype.
lichtkind Su-Shee: it is recognized or it would'nt be headlined by Ix magazine
masak it's not nearly recognized enough. 12:15
Su-Shee lichtkind: don't know. if "ck" was the editor - he's supporting perl anyway for .. every since.

Su-Shee I think I've explained about 20 times within the last 12 weeks that perl isn't dead and perl 6 no vaporware. 12:16
lichtkind Su-Shee: he is supportive but has not much clue about perl 6, moritz_++ was , but what i ment, and i know that because i spoke with him, without general backing no story gets to the frontpage like the perl 6 tut did
Su-Shee which is difficult to tell because international tech media says otherwise..
lichtkind: I know, I write regularly for Heise. 12:17
lichtkind Su-Shee: did you see Perl 6 Tutorial
mom
Su-Shee lichtkind: gimme gimme gimme. ;)
lichtkind Su-Shee: did you see wiki.perl-community.de/cgi-bin/fosw...l6Tutorial
Su-Shee: i tried to write for heise maybe i wil 12:18
Su-Shee lichtkind: I don't think this is how a new technology spreads in the german realm...
lichtkind Su-Shee: what you mean ? 12:19
Su-Shee I mean that I don't think that Heise is the main source of any tech stuff which later on gets more well known (or starts a hype :)
lichtkind: _very_ nicely done. can't you do it in english?

azawawi wonders if rakudo error messages will improve like STD's
STD error/warning messages rock. TimToady++ 17:44
pmichaud: i cant figure out how to highlight comments/pod in rakudo padre's PGE dumper 17:46
17:49 masak left
TimToady azawawi: rakudo hasn't been worrying about error messages much because the plan is to eventually run STD directly 17:56

azawawi i see; now we can use either S:H:P6/STD or rakudo/PGE highlighting in Padre Perl 6. The quick fixe, outline tree, and useful error messages are based currently on the STD highlighter. 18:00
pmurias azawawi: the quick-fix is eclipse inspired? 18:02
azawawi pmurias: yup
pmurias: this is an initial implementation using the right click menu 18:03
pmurias: next step is integration with Ecliptic's CTRL-~, search.cpan.org/~azawawi/Padre-Plug...cliptic.pm 18:04

I would like to know if perl6 has/will have a fast way to perform a deep comparison of data structures ?

eternaleye `alpha: Well, the === operator does a deep comparison of the contents, and =:= checks if two variables are bound to the same container 19:47
`alpha cool
thanks eternaleye

eternaleye Hm, rakudo may not implement it yet, though

eternaleye Might be NYI
`alpha I see
eternaleye Here's a question for the spec-writers: If the block for a ... expression has a slurpy param, what happens? For instance, if I had 2, 3, 5, 7 ... -> *@prev_primes { for @prev_primes[*-1]..* { return $_ if isPrime( $_ ); }; }; would it work? 19:53
s/isPrime( $_ )/isPrime( $_, @prev_primes ) 19:54
[revised] 2, 3, 5, 7 ... -> *@prev_primes { for @prev_primes[*-1]^..* { return $_ if $_ % all( @prev_primes ) != 0; }; }; 20:00

amoc rakudo: say 'value identity is same' if [1,2,3] === [1,2,3] 20:27
p6eval rakudo 1b06df: ( no output )
amoc i think it's because Array is a mutable type. and there identity doesn't belong to their contents.
