Is any way to insert blank lines in the text file?

[goodywp]

Hi,

I have a txt file and need to replace some txt for updating.

Code: Select all

.......
set oldgen=%oldgen: =%
set newgen=%newgen: =%

@echo off &setlocal
set "search=%oldgen%"
set "replace=%newgen%"
set "textfile=Readme-how-to-use-this-package.txt"
set "newfile=indesnew.txt"
(for /f "delims=" %%i in (%textfile%) do (
    set "line=%%i"
    setlocal enabledelayedexpansion
    set "line=!line:%search%=%replace%!"
    echo(!line!
    endlocal
))>"%newfile%"
del %textfile%
rename %newfile%  %textfile%

I can do the job but the thing is that after the converting, the format of this txt file is shrinking in terms of missing blank lines and looks a little bit ugly ...

Is any way to insert new blink line in each paragraph or another work around to do the job?

Thanks

I did try the post suggested and not work as expected. And today I found that post has been withdrawn..

[elzooilogico]

supposed lines doesn't start with [ nor ] this should work

Code: Select all

for /F "tokens=1,* delims=[]" %%i in ('"type "%textfile%"|find /N /V """') do (
   echo(%%j
)

but, as you are doing string substitutions

Code: Select all

>"%newfile%" (
 for /F "tokens=1,* delims=[]" %%i in ('"type "%textfile%"|find /N /V """') do (
   set "line=%%j"
   if "!line!" == "" (
     echo(
   ) else (
     set "line=!line:%search%=%replace%!"
     echo(!line!
   )
 )
)

the

Code: Select all

if "!line!" == "" (
  ...
) else (
  ...
)

block is mandatory as if line is empty you'll end up echoing %search%=%replace%

You can do the same thing using FindStr instead of Find

Code: Select all

@Echo Off
Set "search=%oldgen%"
Set "replace=%newgen%"
Set "textfile=Readme-how-to-use-this-package.txt"
Set "newfile=indesnew.txt"
(
	For /F "Tokens=1* Delims=:" %%A In ('FindStr /N "^" "%textfile%"') Do (
		If "%%B"=="" (
			Echo=
		) Else (
			Set "line=%%B"
			SetLocal EnableDelayedExpansion
			Set "line=!line:%search%=%replace%!"
			Echo=!line!
			EndLocal
		)
	)
)>"%newfile%"
Del "%textfile%"
Ren "%newfile%" "%textfile%"
