vim - Dynamically change spell checking on a key stroke -


hello discovered spelllang if vim. trying achieve following:

  1. when press f7 dialogue opened asking me if want activate french or english dictionary set spelllang=fr spell or set spelllang=en spell
  2. when press f7 again spell disabled

can in vimrc ?

cheers (i using gvim , windows guess won't matter)

yes can achieve this. wrote little script illustration. can put .vimrc.

the key point use of inputlist() prompts user enter number. of course can expand spelllang_list contains list of possible languages desire.

function! <sid>togglespell()     let spelllang_list = [ 'fr', 'en' ]     let string = []      in range(len(spelllang_list))         call add(string, i+1 . ") " . spelllang_list[i])     endfor      if ! &spell         let &spell = 1         let selection = inputlist(string)         let &spelllang = spelllang_list[selection-1]     else         let &spell = 0         echo "'spell' disabled..."     endif endfunction  noremap <f7> :call <sid>togglespell()<cr>

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), ...
