Massive list and massive search and replace?

Calvin Foo

I guess I need to learn from ground up. I only have experience in writing ASP 3.0. and SQL Server.

I guess I just start from there

Maybe anyone can give me a simple guide on How to write a simple replace text script? I’ll further study from there and include a list of text (maybe import from CSV)

There’s very, very, very little to learn. First, follow the instructions in Alan’s second post to you (“REFERENCE” link) LIKE A MONKEY.

Here’s a first script you can run:

#! python
import sys
print "Old style print syntax"
sys.stdout.write("Calvin-Foo's first script -- hello from Python %s\n" % (sys.version,))

You don’t need to know what any of the lines mean or what they do. (Once you get it running, you can hack at it for fun).

There’s a lot complexity in airplanes and elevators and keyboards and phones that you don’t see and don’t need to deal with. It’s really quite similar.

In case it isn’t obvious, you could take YOUR data, in whatever (textual) format, and use Notepad++ to change it with a replacement operation into MY demo format, and then just run with the demo solution.

This avoids programming and could (probably) be made into a N++ macro for easy repetitive running.

As an example, take your original problem statement data (I know it isn’t your real data, but we have none of that here, so…):

1. james - James
2. calvin - Calvin
3. new york - New York

You could change that into the needed input format for the script by this operation:

Find: (?-s)^\d+\. (.+?) - (.+)
Replace: ${1}->${2}
Search mode: Regular expression
Wrap around: Checked
Action: Replace All button

After the replace-all, your data would then look like this:

james->James
calvin->Calvin
new york->New York

which would be a direct feed-in to the demo script.

this seems a bit too complicated for me

Of course, this data transform may involve learning some regular expressions (don’t know your expertise), but I don’t think it is too much to ask people that request a moderately-complex solution to a problem to do some sort of learning of their own along the way.

How to write a simple replace text script?

Well about the simplest one I can think of would be a one-liner:

editor.replace('apple', 'Apple')

this script is FANTASTIC.

i do have a question though- in the final output it prints how many replacements were made, but is there any way to see what the actual replacements were?

looking into the code i see

“”" if self.num_repl_made_in_this_file > 0:

                self.print('replacing "{fw}" with "{rw}" {n} times'.format(
                    fw=find_what, rw=replace_with, n=self.num_repl_made_in_this_file)) """

but i dont see where that would get printed- it doesnt show up in the python console either

again huge thanks for this one

Well…glad you like it.

The self.print() function calls are really meant as debug helpers while testing the script. Thus, in the version of the script above, they don’t do anything because the debug variable is set to False. If you change the 0 to a 1 in this line:

self.debug = True if 0 else False

or simply change it to:

self.debug = True

then the output of the self.print() calls will go to the PythonScript console window. You’ll see the output you indicated you were interested, plus output from other things that happen while the script is running.

@Alan-Kilborn perfect!

Thanks Alan, it work perfectly, Except one specially for me. Appreciate your help if possible:

I want to find only within word boundary.

For example:
Sentence: You are eating apple. The tree have a lot of apples. all the apples is green.
apple->cherry
apples->cherries

Hence, how can I add in a code to made it change only words start or end a transition from space to non-space character (space, common, dot, quote marks, questions mark…).

thanks in advance

You can use \b in the regular expression to insist upon a word boundary; example: \bapple will match have an apple today but will not match have a crabapple today.

Sorry to ask and bother you. I tried to edit your py code as below, but it seems to be a wrong code. Could you advise how to correct:

Not work:

     # FINALLY, the actual replacement!
                editor.rereplace('\b'+find_what+'\b', replace_with)

Not work 2:

     # FINALLY, the actual replacement!
                editor.rereplace(r'\b'+find_what+'\b', replace_with)

This should work: editor.rereplace(r'\b'+find_what+r'\b', replace_with)

I like how you showed initiative in trying to solve the problem yourself…and you had the right idea, you just didn’t take it far enough.
