and why we need an other syntax when we want to delete this first character ? already answered the reason why ! Why can we search for the first character of each line, if any, with the simple regex (?-s)^. So, the second standard character of current line, if any ! In replacement, we just rewrite group 1, only. The ^ symbol is a zero-length assertion, which is the location of the beginning of current line scanned ) as a standard character only, ( not EOL chars ! ) The (?-s) is a in-line modifier, which forces the regex engine to interprets the dot symbol (. Select the Regular expression search modeĬlick once on the Replace All button or several times on the Replace button But, I found this particular example to be something that I can definitely build on in the future and hope that you can too.Tick the Wrap around option, if necessary I’m still quite the noob in regular expressions and much more can be done with them. You can then refer to them in the replacement string several times if you wish. Now, in the replacement, you can refer to these tagged areas by “1”, “2”, “3”, etc….simply the order in which they appear gives them an ordinal number. Then the second section that I’ve tagged is between the and the end of the line, signified by the “$” (dollar sign). For the first piece, it tags the part between the beginning of the line, signified by the “^” (caret) character and the signified by itself. This is how you tag a portion of a string, by putting the expression within parentheses. In the image, you can see that in the FIND expression, you have two sections in parentheses. So to accomplish this I was able to use the Notepad++ Search/Replace dialog in “regular expression” mode like this: Really good regex info can be found on the Notepad++ wiki here. So I played with regular expressions and became aware of how you can “tag” parts of your search expression and then refer to those tagged portions of text in your replacement string to allow you to move things around and copy things. If Notepad++ macros worked in every situation, I’d have been able to use them, but they would simply “malfunction” on me and not allow me to accomplish this. NOTEPAD++ REGULAR EXPRESSION START OF LINE SOFTWAREIf you’ve ever had to move contacts from one piece of software to another you may have come across this problem to create an import file for the destination. So, to start with I have a list of emails like this: Today, I needed to take a list of e-mails and, for each email take the part before the and copy it at the of the line with a tab in between. I’ve been using Notepad++ for some time now and have sort of a love-dislike relationship with it because it’s very powerful…but some things, notably macros don’t exactly work like I’d want them too…and sometimes, I really think they’re buggy. See my blog post about my laziness with regular expressions. I enjoy coding and writing weird SQL! But I’ve never been able to get my head around regular expressions…never really wanted to. I’ve had some very limited success in using them…mostly in a linux command-line grepping situation where I had some very good examples to work from and had no other choice…i.e. I’ve always found regular expressions to be a real un-intuitive mind-bender.
