FindRepl.bat:New regex utility to search and replace strings

[foxidrive]

PS - There is a new answer at S.O. that show a very clear example of /O and /B switches usage; perhaps you want to review it. It is here.

Thanks Antonio, that's useful and explains the /$ switch for me.

[Aacini]

Aacini , its working with "/J" switch but i dont know that your machine produced blanks as compared to my windows xp sp3 32it.

Note that your code execute these 4 commands:

Code: Select all

      type inputfile.txt |FindRepl "View" /a "displayed"

      type inputfile.txt |FindRepl "View" /a "displayed"

      type inputfile.txt |FindRepl "view" /a "displayed"

      type inputfile.txt |FindRepl "view" /a "displayed"

That is, no one of the commands have the /i switch! My modified code execute these commands:

Code: Select all

      type inputfile.txt |FindRepl /i "View" /a "displayed"

      type inputfile.txt |FindRepl "View" /a "displayed"

      type inputfile.txt |FindRepl /i "view" /a "displayed"

      type inputfile.txt |FindRepl "view" /a "displayed"

Sometimes I don't clearly express myself...

IMPORTANT: Note that in the "solution" the replacement string is enclosed in quotes and apostrophes: FindRepl /i "view" /a "'displayed'" /J; this is required because "displayed" (in quotes) is a literal string, but "'displayed'" (in quotes and apostrophes) is a JScript expression!

Aacini, thanks for your clarification. its really my typos error in posting code but your "'displayed'" really had a apostrophes which i cant see yesterday. i reviewed it today and see it has apostrophes!

anyway i had another problem in my new script here:

inputfile.txt

there are two doublecolon : symbols : here
there are two doublequotes marks "symbols" here
there are less and greater than < symbols > here
there are questionmark and asterisk ? symbols * here
there are backslash and slash \ symbols / here
there are pipe and exclaimation marks | symbols ! here

my script here:

Code: Select all

@echo off
echo deleting characters: 

type inputfile.txt |FindRepl ":|'|<|>|\?|\*|\\|/|\||\!" /A "" /Q:'

echo replacements:

type inputfile.txt |FindRepl ":|'|<|>|\?|\*|\\|/|\||\!" /A "[DC]|[DQ]|[LS]|[GR]|[QM]|[ST]|[BS]|[SL]|[PI]|[EM]" /Q:'

pause
exit 

output here:

Code: Select all

deleting characters:


there are  two doublecolon  symbols  here
there are  two doublequotes marks symbols here
there are  less and greater than  symbols  here
there are  questionmark and asterisk  symbols  here
there are  backslash and slash  symbols  here
there are  pipe and exclaimation marks  symbols  here

replacements:


there are  two doublecolon [DC] symbols [DC] here
there are  two doublequotes marks [DQ]symbols[DQ] here
there are  less and greater than [LS] symbols [GR] here
there are  questionmark and asterisk  symbols  here
there are  backslash and slash [PI] symbols [SL] here
there are  pipe and exclaimation marks  symbols  here

Press any key to continue . . .

as shown above:

1) "[QM]" , "[ST]" , "[BS]" , "[EM]" are not displayed.

2) "[PI]" is misplaced and is found in "[BS]" position.

and i do know how to script correctly.

[foxidrive]

Bars, did you describe and provide the output that you are trying to get?

Bars, did you describe and provide the output that you are trying to get?

foxi,

i want a question mark symbol "?" displayed as "[QM]"

i want a asterisk symbol "*" displayed as "[ST]"

i want a backslash symbol "\" displayed as "[BS]"

i want a exclamation mark symbol "!" displayed as "[EM]"

here is supposed output to be displayed (replacement part only):

Code: Select all

there are  two doublecolon [DC] symbols [DC] here
there are  two doublequotes marks [DQ]symbols[DQ] here
there are  less and greater than [LS] symbols [GR] here
there are  questionmark and asterisk [QM] symbols [ST] here
there are  backslash and slash [BS] symbols [SL] here
there are  pipe and exclaimation marks [PI] symbols [EM] here

in my previous post my script output display is (replacement part only) :

Code: Select all

there are  two doublecolon [DC] symbols [DC] here
there are  two doublequotes marks [DQ]symbols[DQ] here
there are  less and greater than [LS] symbols [GR] here
there are  questionmark and asterisk  symbols  here
there are  backslash and slash [PI] symbols [SL] here
there are  pipe and exclaimation marks  symbols  here

my previous script is:

Code: Select all

@echo off
echo deleting characters:

type inputfile.txt |FindRepl ":|'|<|>|\?|\*|\\|/|\||\!" /A "" /Q:'

echo replacements:

type inputfile.txt |FindRepl ":|'|<|>|\?|\*|\\|/|\||\!" /A "[DC]|[DQ]|[LS]|[GR]|[QM]|[ST]|[BS]|[SL]|[PI]|[EM]" /Q:'

pause
exit 

[foxidrive]

To simplify this problem:

This doesn't work because the ? character can't be escaped in the way I tried it below.

Code: Select all

echo a?bcd|findrepl "\?|b|c|d" /A "[QM]|[ST]|[BS]|[EM]"

and it needs to be escaped somehow because this generates an error:

Code: Select all

echo a?bcd|findrepl "?|b|c|d" /A "[QM]|[ST]|[BS]|[EM]"

[Aacini]

This is a subtle bug. I need to carefully review the program in order to find it. However, the cure is simple and the same than before: change the version1 literal-to-literal replacement by the new version 2 regexp-to-JScript replacement:

Code: Select all

C:\> echo a?bcd|findrepl "\?||b||c||d" /A "'[QM]'||'[ST]'||'[BS]'||'[EM]'" /J
a[QM][ST][BS][EM]

[bars143]

Aacini, thanks for answer and now my new script is:

Code: Select all

@echo off

echo INDIVIDUAL REPLACEMENT: 

type inputfile.txt |FindRepl "\|" "'[PI]'" /J >outputfile.txt
type outputfile.txt |FindRepl "\!" "'[EM]'" /J >outputfile.txt 
type outputfile.txt |FindRepl "\*" "'[ST]'" /J >outputfile.txt 
type outputfile.txt |FindRepl "\?" "'[QM]'" /J >outputfile.txt
type outputfile.txt |FindRepl "\\" "'[BS]'" /J >outputfile.txt
type outputfile.txt |FindRepl "\/" "'[SL]'" /J >outputfile.txt 
type outputfile.txt

echo ALTERNATION REPLACEMENT: 

type outputfile.txt |FindRepl ":|'|<|>|\*" /A "[DC]|[DQ]|[LS]|[GR]|[ST]" /Q:'

pause
exit 

inputfile.txt :

Code: Select all

there are  two doublecolon : symbols : here
there are  two doublequotes marks "symbols" here
there are  less and greater than < symbols > here
there are  questionmark and asterisk ? symbols * here
there are  backslash and slash \ symbols / here
there are  pipe and exclaimation marks | symbols ! here

resulting output in console :

Code: Select all

INDIVIDUAL REPLACEMENT:


there are  two doublecolon : symbols : here
there are  two doublequotes marks "symbols" here
there are  less and greater than < symbols > here
there are  questionmark and asterisk [QM] symbols [ST] here
there are  backslash and slash [BS] symbols [SL] here
there are  pipe and exclaimation marks [PI] symbols [EM] here

ALTERNATION REPLACEMENT:


there are  two doublecolon [DC] symbols [DC] here
there are  two doublequotes marks [DQ]symbols[DQ] here
there are  less and greater than [LS] symbols [GR] here
there are  questionmark and asterisk [QM] symbols [ST] here
there are  backslash and slash [BS] symbols [SL] here
there are  pipe and exclaimation marks [PI] symbols [EM] here

Press any key to continue . . .

It can be done in one pass, Bars, but the first term using a pipe needs special handling, using findstr V2.0

Code: Select all

type inputfile.txt |findrepl "(\|)||!||\*||\?||\\||/||:||'||<||>" /A "'[PI]'||'[EM]'||'[ST]'||'[QM]'||'[BS]'||'[SL]'||'[DC]'||'[DQ]'||'[LS]'||'[GR]'" /J /Q:'

EDIT: The first term with pipe works fine when it is placed at the end of the search terms, and this seems to be because three ||| in a row is what causes the problem.
Here the two leading terms in search and replace have been shifted to the last position without any special handling:

Code: Select all

type inputfile.txt |findrepl "!||\*||\?||\\||/||:||'||<||>||\|" /A "'[EM]'||'[ST]'||'[QM]'||'[BS]'||'[SL]'||'[DC]'||'[DQ]'||'[LS]'||'[GR]'||'[PI]'" /J /Q:'

output

Code: Select all

there are  two doublecolon [DC] symbols [DC] here
there are  two doublequotes marks [DQ]symbols[DQ] here
there are  less and greater than [LS] symbols [GR] here
there are  questionmark and asterisk [QM] symbols [ST] here
there are  backslash and slash [BS] symbols [SL] here
there are  pipe and exclaimation marks [PI] symbols [EM] here

thanks Foxi , you got it solved !.

but we have the same scripts except those "(\|)" , where my console report an error : expected ")"... but i cant figure it out what it really means?

when i tried to put a ")" anywhere i chose - something next error is expected "/" then put a "/" anywhere then expected ";" error? got no solution , then i decided to go individual replacement rather than solving this error message where i am no knowledge about error code.

anyway a second thanks,

Bars

It is very simple with JREPL v2.

As literal values:

Code: Select all

jrepl  ": \q < > ? * \ / | !"  "[DC] [DQ] [LS] [GR] [QM] [ST] [BS] [SL] [PI] [EM]"  /l /x /t " " /f input.txt

Or as a regular expressions:

Code: Select all

jrepl ": \q < > \? \* \\ / \| !" "[DC] [DQ] [LS] [GR] [QM] [ST] [BS] [SL] [PI] [EM]" /x /t " " /f input.txt

i though that jrepl has no alternation like findrepl

thanks for suggestion Dave its working too.

Aacini and dbenham, you two blokes have created brilliant tools with these Jscript enhanced batch files.
If I had any sway in Microsoft then I'd get them included in a Windows Update patch so that administrators and enthusiasts everywhere can benefit.

Below I have a suggestion to help people use your tools, because there is a fair amount of chatter and questions in the main threads,
if you both think it is worthwhile then I'd suggest that you create dedicated threads called something like:

FindRepl: Examples and tutorials
FindRepl: Code
FindRepl: Discussion

Jrepl: Examples and tutorials
Jrepl: Code
Jrepl: Discussion


The current threads can be renamed to the : Discussion threads.

In the Example threads you'd keep all the samples of code, and explanations of how they can be used
A Code thread can have a history of the code releases with a LARGE message at the top to see the last post for the most recent version, and all linked appropriately to the other threads.
- and the mods here can move any posts with conversations/questions to the Discussion threads.

It might make the threads easier to maintain, plus searchers can browse the appropriate threads for the valuable tips and tricks that many of us need to effectively use your gems.
There's some initial work to get it set up but I'm also willing to help if needed.

[foxidrive]

Bars, see my previous post today regarding the pipe and special handling in FindRepl, as it turns out there is another way of arranging the terms:

i second foxidrive's suggestion. both are marvelous tools with so much features built in..
