How to use Regular Expression for Search & Replace in Eclipse ?

[Ashish Vijaywargiya-5]

Hello Jacques,

I noticed that you have done couple of work in the area to search any
string and replace with other string by the use of Regular Expression
using Eclipse.

Do we have some "How To docs" on ofbiz confluence or somewhere else ?
(searched on confluence but didn't fine any :( )
Are you using some plugin for this job ?
Do you have some script that you use and update as per the new
requirement for replacements of any string ?

Can you please share your thoughts on this as soon as you get a chance.
If this has been discussed on mailing list then can you please share me
that thread ?

Thanks in advance for any pointer !

Hi Ashish,

You don't need anything else than last Eclipse version.

When it comes to large changes, I don't like much hand-coding. It's tedious and error prone.
So, as you can see in the following links I have been batlle from the beginning for a S/R powerful feature in Eclipse but I had to
wait 3.4M1 to have the R part really working.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=196783
https://bugs.eclipse.org/bugs/show_bug.cgi?id=155565
BTW, I'm still waiting for this one :o)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=200039

I will soon write a tip in http://docs.ofbiz.org/display/OFBIZ/Eclipse+Tips

+1, it would be great to have this feature in next release of Eclipse.

I'll wait for your tips on this but in the meantime I will try to
explore this feature from the help content available in eclipse at Help
--> Help Contents (by searching "regular expression").
Please share the tips through email as soon as you are done with that.

FYI, I have enabled the mail notification feature for any changes on the
confluence pages but in case if I miss your changes then your email on
ML will be of great help for me :-).

Also Ashish, don't worry about the
741 remaining occurences of
<service name=(.*)engine="simple"(.*)\R(.*)location="org.ofbiz

I can deal with that if you want, tough of course being more to do large Searchs/Replacements would help.
But we warned, it's an hard beast and I have been bitten many times by it ;o)

I am fine if it takes less time for you. Please do the needful as soon
as you get a chance.
As you can see in the previous email in another thread that David is
also interested to get rid of this ASAP before ofbiz another release in
end of march.
 
Yesterday I have spent around 20 minutes in night for all the commits I
have done today and in my opinion that is considerable time frame for
such work.
Thanks !

Well, the feature itself uses the standard java regular expressions and is actually fairly simple to understand. I would recommend to have a go at regular expressions before trying that feature. For instance, you can try

http://www.gskinner.com/RegExr/
or
http://www.regextester.com


to test the results. Another great read is also:

http://java.sun.com/developer/technicalArticles/releases/1.4regex/

Be aware that there are different types of regexp. So not all commands may work (luckily, eclipse displays the available commands on the input dialog)


Btw, a great one I use quite often is this: <TAG\b[^>]*>(.*?)</TAG>
It'll grab the start and ending ending of a specified html tag. You can then use the select the inner element using $1 :)

Thanks Paul,

I think it will be great to share our tips in a wiki page. I will open one soon...

When I have done regexp search and replace operations on some of my own
code I like to codify it in a python script. Sometimes the script may
contain the list of files that are to be worked on, sometimes I just ask
the script to glob a pattern recursively acting on files. Recently I
have also used the same sort of technique for transforming xml data
files using the standard xml processing lib's in python to help myself
with customer data import tasks.
