**OderWat** Thank you, everything was actually easier than I thought. In
MemFiles have stringify operator **$** for type MemSclise. What is interesting,
with **lines** iterator code works somehow faster than code with iterator
**memSlices**. Why?
Works 4 seconds for a file in rows 3_000_000
pattern = ARGS[1]
rex = pattern.re
for line in fMem.lines:
countLine+=1
if line.match(rex).isSome:
countRepl+=1
fOut.writeLine(line.replace(rex, ARGS[2]))
else: fOut.writeLine(line)
# end for
Works 4.8 seconds for a file in rows 3_000_000
pattern = ARGS[1]
rex = pattern.re
for slice in fMem.memSlices:
if slice.size > 0:
countLine+=1
line = $slice
if line.match(rex).isSome:
countRepl+=1
fOut.writeLine(line.replace(rex, ARGS[2]))
else:
fOut.writeLine(line)
# end for
