Question

I wanted to use regular expressions in eclipse to adept code to a software update.

instead of

{$CFG->prefix}example1.xy

the code needs to be:

{example1}.xy

to work.

another example would be:

{$CFG->prefix}example2.foo

>

{example2}.foo

constant parts are : {$CFG->prefix}; .

i tried the following (i used whitespaces to make reading easier):

Find: \{\$CFG-\>prefix\} ([a-z]|[0-9])* \. ([a-z]|[0-9])*

Which will find the requested String. I struggle in replacing it.

i can use ,/1to store the result of the regex and use it in the replacement (right?) but i am not sure how i can modify/manipulate this result.

thanks for any help.

Answer 1

Try the following search and replace :

Find: \{\$CFG->prefix\}([a-z0-9]*)\.([a-z0-9]*)

Replace with : {\1}.\2

Using the above the following :

Here is a quick screen-cast to show this in action.

Changes made to the OP’s Find reg-ex

In order to get the above find-replace to work, I had to make the following changes to the OP’s find expression :

1. Removed whitespaces.
2. Moved the Greedy Match modifier inside the groups : i.e. ([...]*) instead of ([...])*
3. Corrected the character set : i.e [a-z0-9] instead of [a-z]|[0-9]
4. Introduced another Group which captures the part after the period. This however is not strictly needed but may be useful in some scenarios.
