I've done a little experiment. The files I'm searching through are on a network drive and added to my Documents Library on Windows 7 (libraries\Documents).

I've got some basic functionality compiling, and I'm testing it. I still need to add callbacks and allow users to register scripts. (For testing, it's hard-coded to run a particular file.) I've been using PN for years and ever since extensions became possible I've been wanting to write one for Perl. I recently finished my Masters, and I am freelancing while I seek funding for a PhD, so I have occasional free time now. I hope to release something by the end of February, but it depends on how busy I am. I am a freelancer and some days I'm busier than others. Yesterday, I got several hours in, but today, I did almost nothing on the plugin because I had a lot of paying work. So basically I should never delete any objects, and I should free any non-const strings returned to me. Now I need to figure out how to make Perl play nice with <code>shared_ptr</code>. Perl is written in C, and I'm casting object pointers to <code>void*</code> so my Perl objects can store them. A pointer to a <code>shared_ptr</code>, cast to a <code>void*</code> - I don't think <code>shared_ptr</code> will track that properly.

However I don't know if you could easily get it so that it was terminated either by line end or a closing character. You'd need to experiment. The comment thing is unfortunate, there's no support for regular expressions for matching at the moment, although there may be something like this in the future.

In the case of IDocumentPtr this is relaxed a bit, as it's useful to tie things to doc instances, but make sure you use shared_ptr to keep the reference. For event sinks and other types where PN takes a <code><classname>Ptr</code> instance, you should create and store these directly in <code>shared_ptr</code>, and then the <code>shared_ptr</code> gubbins will take care of lifetime management - you can pass to PN and forget and <code>shared_ptr</code> will take care of deletion when there are no references left. From my recollection (I don't have the code in front of me) menu item collections are copied so you don't need to keep them around, I'd have to double-check. Any string returned to you non-const must be released with PN::ReleaseString. In most cases I've switched to using <code>PN::BaseString</code> for this as this removes the need for this, the rest will eventually follow. Anything else you'll need to copy to keep. Hope this helps! Out of interest, what are you building?

First, all the interfaces have a destructor in the class definition. One group of them by their nature seem to be singleton objects, and therefore I shouldn't ever delete them (IPN, IOptions, etc.). Another group is things I define my own descendant class for, and therefore I should create and destroy them myself (event sinks, for example). However, there are two groups I'm not sure about. One of them is things like IDocument. Are these pointers to copies of objects that I take ownership of, or are they pointers to the same objects the main program is using, and therefore the main program retains ownership? The other group (well, a group of one) is MenuItems, which I pass to the main program via AddPluginMenuItems. Does the main program take ownership of this, or should I delete it when the plugin exits? Most of the strings passed back and forth seem to be either const'ed or passed via PN::BaseString. I assume that any const char*/wchar_t* I pass to the main program are copied if necessary, and thus I can safely free them after the call. Similarly, if I get them from the main program, I assume I have to copy them if I want to keep them around. There are, however, three examples of non-const wchar_t* being returned. On two of those, there is a comment indicating that I should use PN::ReleaseString when I'm done with it. Am I correct in my assumption that the other one should be treated the same way? The method in question is: <code>virtual wchar_t* InputBox(const wchar_t* title, const wchar_t* caption) = 0;</code> Creating a new scheme in PN portable (Roody) http://pnotepad.org/forums/topic/7445#post-10618 Sat, 28 Jan 2012 03:35:44 +0000 Roody 10618@http://pnotepad.org/forums/ It took me some time to find where things are explained, too. It seems that all of the .scheme files refer to lexers that are built-in to the Scintilla SciLexer.dll file.

However I love that PN does actually support multi-line regex - i.e. that [\s\S] WILL match across new-line chars. Though I suppose that it would be nice to have a "single-line/muti-line" option that would either look at the document on a line-by-line basis or (as it is currently) as a single stream. Since this is one area of PN that I use extensively I too will be looking into improving PN's regex support. For my personal use I have already added the <a href="http://code.google.com/p/pnotepad/issues/detail?id=1534&q=regex&sort=-id">format_perl</a> features from Xpressive. I also spectacularly failed in my attempt to add Unicode support for replace! However, I am still looking into how you managed to get unicode search working and I am confident that I can sort things out. My fail-safe plan is to parse the replace string and "encode" the unicode chars into \x00\x00 etc. so that the replace string can remain a std::string. However, I know next to nothing about the non-ASCII world so I don't know how successful I will be. I will probably pester you with questions. :) AutoIt3 - Updated au3.scheme file (2012, v3.3.8.0) (simon) http://pnotepad.org/forums/topic/7351#post-10569 Thu, 12 Jan 2012 10:21:59 +0000 simon 10569@http://pnotepad.org/forums/ Thanks for your contribution!

This would be great content for the docs or blog - perhaps both. It's definitely worth looking into Xpressive's newline matching behaviour. I agree that generally we don't want to match newlines, although for some multi-line matching it can be useful. RegEx in PN - Example (NickDMax) http://pnotepad.org/forums/topic/7416#post-10563 Wed, 11 Jan 2012 23:37:56 +0000 NickDMax 10563@http://pnotepad.org/forums/ As long as we are on the topic of RegEx: <a href="http://code.google.com/p/pnotepad/issues/detail?id=1533&sort=-id">There is a defect logged about the nature of the dot (.) operator.</a> As I understand it the dot operator should not match to EOL chars. The XPressive search is given the option regex_constants::not_dot_newline which keeps the dot from matching to \n. However windows tends to use \r\n as a newline marker and the dot will match to \r. So when it comes to the end of the line, the dot operator can be a little funny. So often it is best just to not use it! the dot operator operates as: [^\n] -- matches everything BUT the new line char. What windows users typically expect: [^\r\n] -- match everything BUT the windows new line chars How to match any char: [\s\S] -- will match any char. Example: Say you want to replace the inner most div tags with span tags. Find What: <div>(?![\s\S]*?<div>[\s\S]*)([\s\S]*?)</div> Replace with: \1 The basic version of this regex is: <div>([\s\S]*?)</div> this captures all chars inside of a div tag-- however if the tags are nested then problems happen since this will match the first open div tag with the first close div tag. So we add an assertion that the match does not include a div tag itself. The result is that we will look for the inner most div tag (assuming of course valid HTML). The point of the example is that we can use [\s\S] to capture all chars in the tags (including new line chars). \s is the class of all white-space characters and \S is the set of all NON-white-space characters. One could equally use [\w\W] or [\d\D] Sometimes however it is nice to be able to limit our searches to a single line. Using [\s\S] can get us into trouble here since even something like: //([\s\S]*)$ an attempt to grab the content of an end-of-line comment - but this will match past the end of lines. We would need: //([\s\S]*?)$ to ensure the non-greedy match. Or we could just be more specific on what we were looking for: //([^\r\n]*) So it is true that the dot operator is a little buggy in PN (when operating of files using \r\n or \r line endings) but a little knowledge can get you around and let you use the full power of PN's regular expression search and replace.

Well people often use TODO: tags in comments to identify tasks that need to be completed. The following PyPn script will extract all TODO: EOL comments (on their own line) into a new file. <pre><code>############################################################################### ## Extract all ToDo lines into a new file ## By: NickDMax import pn import scintilla from pypn.decorators import script @script("Extract Todo","CPP Utils") def Name(): """ Extract TODO: lines into a new file """ #recorded search/replace wrapped in an UndoAction doc = pn.CurrentDoc() sci = scintilla.Scintilla(doc) sci.BeginUndoAction() opt = pn.GetUserSearchOptions() opt.FindText = u'^(?:(?![ \\t]*//[ \\t]*(?i:TODO:)).*(?:\\r\\n)+|[ \\t]*//[ \\t]*(?i:TODO:)[ \\t]*(.*)(\\r\\n)?(?:\\r\\n)*)' opt.MatchWholeWord = False opt.MatchCase = False opt.UseRegExp = True opt.SearchBackwards = False opt.LoopOK = True opt.UseSlashes = False opt.ReplaceText = u'\\1\\2' opt.ReplaceInSelection = False doc.ReplaceAll(opt) sci.EndUndoAction() #Now to save the text in a new file startPos = 0 endPos = sci.Length text = sci.GetTextRange(startPos, endPos) newDoc = pn.NewDocument("") newsci = scintilla.Scintilla(newDoc) newsci.BeginUndoAction() newsci.AppendText(len(text), text) newsci.EndUndoAction() #restore the document sci.Undo();</code></pre> Of course I have only tested this with one test file: <pre><code>#include<iostream> //TODO: remember to do something here. int main() { //TODO: remember to do something else here // TODO: oh don't forget to do this return 0; } // ToDo: and then there is this here too.</code></pre> So a little more testing is probably needed to ensure that it is working as expected.

The answer is of course: Yes - but would you really want to. Search: ^(?:(?!LogStep).*(?:\r\n)+)|(?:LogStep$\s*"([^"]+)"\s*$.*(\r\n)(\r\n)*) Replace: \1\2 hit <Replace All> This is a pretty complex RegEx so lets break it up. The overall structure is A|B A: RegEx to match the rest of a line NOT BEGINNING with "LogStep" B: RegEx to match the rest of a line that DOES begin with "LogStep" - capture the text (and a CRLF new line) The whole thing is wrapped in a the expression: ^(?:A|B) where ^ asserts the beginning of a line, and (?: ) is a non-capture group - that is it treated as a group but not captured into \1 or \2 etc. - this outer non-capture group creates separation. Without it our expression would need to be: ^A|^B Since the expression A contains no capture groups BUT the overall expression DOES contain capture 2 capture groups \1 and \2 will be empty when expression A matches. When B matches \1 is the text inside of the quotation marks, and \2 is a crlf (\r\n) pair.
