match - How to ignore Characters while matching in vim -


i'm trying vim (gvim on windows 7) since past few days , must interesting though have steep learning curve.

i have decently built _vimrc file now, forum, looking specific pattern ignore technique.

suppose, in text file have string so:

10000000c9abcdef

and in same file have same string, separated : @ every 2 characters so,

10:00:00:00:c9:ab:cd:ef

or, have line such as,

hostname portname switchname

as as

hostname_portname_switchname

how can make vim match 10000000c9abcdef 10:00:00:00:c9:ab:cd:ef , match hostname portname switchname hostname_portname_switchname ?

as of now, if place cursor below 10:00:00:00:c9:ab:cd:ef , hit *, highlights , matches 10:00:00:00:c9:ab:cd:ef, how can make match 10000000c9abcdef ? or hostname_portname_switchname hostname portname switchname ?

basically, want vim ignore non word characters ( assuming non word characters space, tab, :, ::, comma, colon, semicolon etc.)

is there way ?

after selecting match *, can modify search pattern change literal non-keyword character (\k\@!.) match non-keyword, optionally (\?):

:let @/ = substitute(@/, '\k\@!.', '\\%(\\k\\@!.\\)\\?', 'g')

to make work _, have either adapt regular expression, or :set iskeyword-=_.

c++ - End of file on pipe magic during open -

i have c++ application in starting process(wireshark) following. if (fp == null){ fp = popen(processpath, "r"); //processpath process want start if (!fp){ throw std::invalid_argument("cannot start process"); } fprintf(fp, d_msg);//d_msg input want provide process } else if(fp != null){ fprintf(fp, d_msg); } the problem when execute c++ application, start wireshark error end of file on pipe magic during open what should avoid that? also tried using mkfifo create named pipe , execute it. used this: if (fp == null){ system("mkfifo /tmp/mine.pcap"); fp = popen("wireshark -k -i /tmp/mine.pcap", "r"); if (!fp){ dout << "cannot start wireshark"<<std::endl; throw std::invalid_argument("cannot start wireshark"); } input = fopen("/tmp/mine.pcap", "wb"); fprintf(input , d_msg); fclose(input)...

data.table making a copy of table in R -

i doing this: myfun <- function(inputvar_vec){ # inputvar_vec input vector # # result = output vector return(result) } dt[, result := lapply(.sd, myfun), = byvar, .sdcols = inputvar] i getting following warning: warning message: `in `[.data.table`(df1, , `:=`(prop, lapply(.sd, propeventinlastk)), : invalid .internal.selfref detected , fixed taking copy of whole table, := can add new column reference. @ earlier point, data.table has been copied r (or been created manually using structure() or similar). (and more stuff) .... ` my guess because stacking result vectors (after operation), copy being made? can suggest method remove warning? have done using apply functions , thought should extendable here too. my other question is: can pass chunk of rows data frame (subsetted using statement), , call function myfun operate on that? adding example requested # generate data n = 10000 default=na value = 1 df = data.table(id = sample(1:5000, n, replace=true), ...
