Generally no, but single-line patterns are normal with getline()+setline():
for lnr in range(a:firstline, a:lastline)
let line=getline(lnr)
let newline=substitute(line, pattern, replacement, flags)
if line isnot# newline
call setline(lnr, newline)
endif
endfor
Marks won't get lost in this case, though I would prefer the following:
let s:F={}
function s:F.histget(history)
let r=[]
while 1
let histentry=histget(a:history, -1)
if histdel(a:history, -1)
call insert(r, histentry)
else
return r
endif
endwhile
endfunction
function s:F.histextend(history, histlst)
while !empty(a:histlst)
call histadd(a:history, remove(a:histlst, 0))
endwhile
return a:histlst
endfunction
function Replace(pat, repl, f) range
let savedhistory=s:F.histget('search')
let savedwinview=winsaveview()
try
keepjumps lockmarks
\ execut a:firstline.','.a:lastline.'sm/'.escape(a:pat, '/').'/'
\.escape(a:repl, '/').'/'.a:f
finally
call s:F.histextend('search', savedhistory)
call winrestview(savedwinview)
endtry
endfunction
Unlike previous one, it supports multiline patterns.
