I got this map for formating css into a one liner.
map <silent> <leader>cssclean :%s#\v/\*([^*]\|[\r\n]\|(\*+([^*/]\|[\r\n])))*\*+/##g<Bar>:call CssPretty()<Bar> :%le<Bar>:%s/{\_.\{-}}/\=substitute(submatch(0), '\n', '', 'g')/<Bar>:nohl<cr>Gdd
This map requires CssPretty.
Now I want to call this like :call CssClean() . I tried putting this one by reading this vim tip, but it didn't work.
What was the code of that function?
function CssClean()
%s#\v/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/##g
call CssPretty()
%le
%s/{\_.\{-}}/\=substitute(submatch(0), '\n', '', 'g')/
nohl
normal! Gdd
endfunction
should work fine.

I have developed a function which will take a list of files and will do some statistical tests and will generate a excel file. In the last line of function (return object) I want the function will return a excel file with same names as input file names. In my example it will give list_file.xlsx. IF I enter another file let's say tslist_file it should automatically return tslist_file.xlsx. The function is properly working. Suggest me how I code last line of the function so that I can generalise it.
newey<-function(list_files){
tsmom<-do.call(cbind,lapply(list_files,function(x) read_excel(x)[,2]))
tsmom<-xts(tsmom[,1:5],order.by = seq(as.Date("2005-02-01"),length=183,by="months")-1)
names(tsmom)<-c("tsmom121","tsmom123","tsmom126","tsmom129","tsmom1212")
## newey west
newey_west<-function(x){
model<-lm(x~1)
newey_west<-coeftest(model,vcov=NeweyWest(model,verbose=T))
newey_west[c(1,3,4)]
}
## running newey west
cs_nw_full<-do.call(cbind,lapply(tsmom,newey_west))
library(gtools)
p_values<-cs_nw_full[3,]
cs_nw_full[2,]<-paste0(cs_nw_full[2,],stars.pval(p_values))
write.xlsx(cs_nw_full,"list_file.xlsx")
}
Try:
write.xlsx(cs_nw_full, paste0(eval(substitute(list_files)), ".xlsx"))
Edit:
#jeetkamal is absolutely right - you need to use
write.xlsx(cs_nw_full, paste0(deparse(substitute(list_files)), ".xlsx"))
here.
I apologize for the mistake. eval wold only work if list_files was e.g. the name of a file, not a list object.
I use Rselenium and I use javascript queries.
The query in javascript is this:
document.querySelectorAll('ul#test div.mytext')[1].innerText.split('\n').filter(x => x).join('???')
When I try to run it in RSelenium code I use this:
remDr$executeScript('return document.querySelectorAll(\'ul#test div.mytext\')[ 1 ].innerText.split(\'//\n\').filter(x => x).join(\'???\')', args = list("dummy"))
However I receive an error and I belive it is due to \n character
How can I write it properly?
You are using single quotes for delimiting the code you want to run when it also contains single quotes. Since there are no double quotes in the expression, try:
remDr$executeScript("return document.querySelectorAll(\'ul#test div.mytext\')[ 1 ].innerText.split(\'//\n\').filter(x => x).join(\'???\')", args = list("dummy"))
Here is my css part of css file.
body{
width:1100px;
height:800px;
}
div.main{
margin:20px auto 0 auto;
background-color:#f7f7f7;
}
I want to rewrite it as below.
body{width:1100px;height:800px;}
div.main{margin:20px auto 0 auto;background-color:#f7f7f7;}
All attritutions and values rewritten as only one line,is there a smarty vim command to do the job?
One option would be
g/{/,/}/j
which breaks down as
g start a global command
{ search for {
,/}/ for each match, set a range up until the }
j join the range
Note that this might be to naïve as-is. This doesn't take into account nested brackets. You might first want to set a visual range to the textblock you like to change.
You could use the J or gJ (alternative that doesn't add spaces) commands. They can be run in visual mode to join all selected lines, or take a count.
Alternatively, the splitjoin.vim plugin provides specific support for css rules as you are asking. With the cursor over the first line of the css block, type gJ to join the whole block into a single line.
Either way, you may want/need to run a replace to remove leading spaces before joining - :s/^\s\+// before joining the lines.
EDIT: I guess a 'smarty' way to do this, and without using plugins, would be the following macro: vf}:s/^\s\+/^MgvgJ (the ^M means pressing the enter key - you may have to enter the macro manually to get this). Use it by putting the cursor at the beginning of the line at the top of the css rule you want to rewrite.
As #romainl said, you should use a minifier. However I am going to assume what you really want is a way to glance at your css rules quickly. If that is the case then I suggest you look into folding. #Luc Hermitte gave a great answer on this subject on the post: Using vi, how can I make CSS rules into one liners?
Below is a variant of #Luc Hermitte answer. Put the following in ~/.vim/ftplugin/css_fold.vim:
let b:width = 25
" Use the following mappings to adjust the foldtext "columns"
nnoremap <silent> <buffer> >s :<c-u>let b:width+=v:count1<cr><c-l>
nnoremap <silent> <buffer> <s :<c-u>let b:width-=v:count1<cr><c-l>
if !exists('*s:CssFoldText')
function! s:CssFoldText()
let line = printf("% *s {", -1*b:width, substitute(getline(v:foldstart), "{\s*$", "", ""))
let nnum = nextnonblank(v:foldstart + 1)
let lst = []
while nnum <= v:foldend
let line = line . " " . substitute(getline(nnum), "^\s*", "", "")
let nnum += 1
endwhile
return line
endfunction
map <SID>xx <SID>xx
let s:sid = substitute(maparg("<SID>xx"),'xx$','', '')
unmap <SID>xx
endif
exe "setlocal foldtext=" . s:sid . "CssFoldText()"
setlocal foldmethod=syntax
Now you can use folding commands like zM to close all folds, zR to open all folds, and za to toggle the current fold. Vimcasts has a nice screencast on this topic, How to fold.
For more information see:
:h folds
:h 'foldtext'
:h 'foldmethod'
:h za
:h zR
:h zM
I'm trying to concatenate PHP variables into an "onclick" function.
Here is the line I'm having trouble with (look for the "onclick" part):
$imagecontent = '<div class="imagensfw" id="image'.$id.'" style="width:'.round($wd).'px;height:'.round($ht).'px;" onclick="viewimage(image'.$id.','.round($wd).','.$url.');"><p>Image</div>';
I'm particularly having trouble with concatenating the $url variable. I'd want to put it between quotes, but if I do so, the "onclick" function becomes all messed up (when the code is displayed in the browser).
I think that putting the URL address ($url variable as a parameter in the onclick) between quotes will fix the error its shooting:
Error : missing ) after argument list
Here's my short Javascript function if you're interested:
function viewimage(id,width,url){
var image = document.getElementById(id);
image.innerHTML = '<img src="'+url+'" width="'+width+'" alt="Image" />';
}
Here's what I tried but didn't work (i.e. messed up the code):
onclick="viewimage(image'.$id.','.round($wd).', **"** '.$url.' **"** );"
(Noticed the double quotes added between the $url variable).
Thank you for your time.
Have you tried using variable parsing? From the link's example:
$beer = 'Heineken';
echo "He drank some ${beer}s";
This should simplify the construction of your string.
Silly me, I just noticed an error on my part. I thought we could use double quotes in an "onclick" function. Turns out not, we have to use single quotes ( ' ). It fixed my problem. Thanks!
I would like to come up with a Vim substitution command to turn multi-line CSS rules, like this one:
#main {
padding: 0;
margin: 10px auto;
}
into compacted single-line rules, like so:
#main {padding:0;margin:10px auto;}
I have a ton of CSS rules that are taking up too many lines, and I cannot figure out the :%s/ commands to use.
Here's a one-liner:
:%s/{\_.\{-}}/\=substitute(submatch(0), '\n', '', 'g')/
\_. matches any character, including a newline, and \{-} is the non-greedy version of *, so {\_.\{-}} matches everything between a matching pair of curly braces, inclusive.
The \= allows you to substitute the result of a vim expression, which we here use to strip out all the newlines '\n' from the matched text (in submatch(0)) using the substitute() function.
The inverse (converting the one-line version to multi-line) can also be done as a one liner:
:%s/{\_.\{-}}/\=substitute(submatch(0), '[{;]', '\0\r', 'g')/
If you are at the beginning or end of the rule, V%J will join it into a single line:
Go to the opening (or closing) brace
Hit V to enter visual mode
Hit % to match the other brace, selecting the whole rule
Hit J to join the lines
Try something like this:
:%s/{\n/{/g
:%s/;\n/;/g
:%s/{\s+/{/g
:%s/;\s+/;/g
This removes the newlines after opening braces and semicolons ('{' and ';') and then removes the extra whitespace between the concatenated lines.
If you want to change the file, go for rampion's solution.
If you don't want (or can't) change the file, you can play with a custom folding as it permits to choose what and how to display the folded text. For instance:
" {rtp}/fold/css-fold.vim
" [-- local settings --] {{{1
setlocal foldexpr=CssFold(v:lnum)
setlocal foldtext=CssFoldText()
let b:width1 = 20
let b:width2 = 15
nnoremap <buffer> + :let b:width2+=1<cr><c-l>
nnoremap <buffer> - :let b:width2-=1<cr><c-l>
" [-- global definitions --] {{{1
if exists('*CssFold')
setlocal foldmethod=expr
" finish
endif
function! CssFold(lnum)
let cline = getline(a:lnum)
if cline =~ '{\s*$'
return 'a1'
elseif cline =~ '}\s*$'
return 's1'
else
return '='
endif
endfunction
function! s:Complete(txt, width)
let length = strlen(a:txt)
if length > a:width
return a:txt
endif
return a:txt . repeat(' ', a:width - length)
endfunction
function! CssFoldText()
let lnum = v:foldstart
let txt = s:Complete(getline(lnum), b:width1)
let lnum += 1
while lnum < v:foldend
let add = s:Complete(substitute(getline(lnum), '^\s*\(\S\+\)\s*:\s*\(.\{-}\)\s*;\s*$', '\1: \2;', ''), b:width2)
if add !~ '^\s*$'
let txt .= ' ' . add
endif
let lnum += 1
endwhile
return txt. '}'
endfunction
I leave the sorting of the fields as exercise. Hint: get all the lines between v:foldstart+1 and v:voldend in a List, sort the list, build the string, and that's all.
I won’t answer the question directly, but instead I suggest you to reconsider your needs. I think that your “bad” example is in fact the better one. It is more readable, easier to modify and reason about. Good indentation is very important not only when it comes to programming languages, but also in CSS and HTML.
You mention that CSS rules are “taking up too many lines”. If you are worried about file size, you should consider using CSS and JS minifiers like YUI Compressor instead of making the code less readable.
A convenient way of doing this transformation is to run the following
short command:
:g/{/,/}/j
Go to the first line of the file, and use the command gqG to run the whole file through the formatter. Assuming runs of nonempty lines should be collapsed in the whole file.
