Suggestion: Find in Files from command line
-
…grep…
Maybe grep isn’t great for multiple directories that aren’t in the same tree? Too much to specify, or maybe there’s a nice way to do something like that via a config file?
Specifying such a thing is problematic even for the best tools.
It is a weakness for Notepad++ as well.Plus grep uses yare (yet another regex engine).
The grepper in RegexBuddy allows me to pick the regex engine I want to use (typically I set it to the same one as N++, i.e., Boost).<start_unpaid_commercial>
RegexBuddy really is a great value, for I think 35USD.

@Alan-Kilborn - to quote the famous “how dare are you??” :-D
To be honest, I never had a problem with it. Yes, there are better solutions, like the one I posted, but for what I use it for, it’s good enough. Maybe because I only use utf8 encoded files.

how dare are you?
:-)
N++'s searching is slow, and as previously mentioned, how does one search several different trees? Also, you can’t do anything else with it while it is conducting a search.
It’s perfectly fine for most things (interactive find-next, find all in current file, …), but when you get into searching a lot of files, well there are other and better ways to skin that cat.
And since that is what the beginning of this thread was about (automating an already not-great feature), I say “meh” to the original idea. Not something I’d use. But I respect those that would, and their opinions on the topic.
-
The idea is great, because then I can start a new instance easily and it is not blocking my current instance.

If I’m considering “calling out” like that, I’ll call out to a more capable searching program. :-)
And when that more-capable program shows me the hits and I want to go to one of them, I’ll have that program call back into Notepad++ to take me to the file and hit line. -
I’m not sure I understand, but in the end it depends on personal preference anyway.
I mean, if I use Npp because of its search function, then I think I’m using the wrong tool for the job.
On the other hand, if I mainly edit, then it’s good to have a powerful search function like Npp has, and if it can be easily launched from Npp and doesn’t block me - all the better. -
Well, in theory we could put together all we know and create the desired functionality via scripting…if it isn’t picked up natively. There’d be a lot of individual pieces, but I can’t think of anything that would be a “stopper”.
-
Yes, that (usually) always works :-D
-
And some of the pieces are:
- invoke new instance of N++ with new parameters on the command line
- command line pickoff of parameters (@Ekopalypse has showed us how to do this in the past)
- invoking of the Find in Files dialog after N++ startup
- filling in the fields on Find in Files with command line data
- starting the Find in Files running
So, okay, only 4 basic steps, but some of those steps have a lot of “meat” to them.
I don’t know that I have sufficient interest in the base topic to work up a script, but the script-writer in me thinks that writing it would be more fun than using it would be useful. :-)

YAREST (Yet Another Regular Expression Search Tool)
I use grepWin from Stefans Tools.
It’s FOSS, it’s also available in the PortableApps.com platform, it uses Boost (or plain text) for searching, it can be easily configured to invoke Npp at the desired found line [ grepWin :: Settings > Editor ]:
C:\programs\Notepad++\notepad++.exe -n%line% "%path%"it works well as a Run menu command:
<Command name="grepWin" Ctrl="no" Alt="no" Shift="no" Key="0">grepWin /searchpath:"$(CURRENT_DIRECTORY)" /filemask:"*.*"</Command>and I find it nicely bridges the CL/GUI divide. It took a very small amount of work (a batch file wrapper) to make it assume folder and file extension defaults as I prefer them for regular CL invocations. [But sometimes I’ll still fire up GnuWin32 grep (for one thing it’s less to type <grin>)]

grepWin…it uses Boost
That it uses Boost’s regex engine is a bit obscure – it doesn’t seem to advertise that – is a definite plus for N++ users that are used to it for searching.

I don’t think the author considers it a major selling point; to many people RE is RE, right up until they get bitten by the flavor differences.The author states on the mini help page on his website:
grepWin uses the boost regex engine to do its work, with the Perl Regular Expression Syntax.The F1 help screen in grepWin has links to the top-level (non version specific) Boost documentation (which as of today has ‘release’ resolving to ‘1_77_0’):
https://www.boost.org/doc/libs/release/libs/regex/doc/html/boost_regex/syntax/perl_syntax.html https://www.boost.org/doc/libs/release/libs/regex/doc/html/boost_regex/syntax/character_classes.htmlThe project source code on github for the current version (2.08) shows it using Boost 1.76.0.0.
I have not tried any form of “proof of Boostness” as I typically use grepWin for searches similar to: “Which files in this project reference a particular manifest constant?” or “Have I defined this word in another text file in this folder tree?”
It does offer a replace function, which works well with plain text replacements. I have only tried regex replacements a couple of times (it worked fine). By default, grepWin saves a copy of the original file with a .bak extension added for both replacement styles.

You said that very well. :-)

I’m not really sure what that means (the last part).
I’ve also seen other related references calling it PCRE (Perl Compatible Regular Expression) syntax.
To me, it’s “Boost RE syntax”. -
@Alan-Kilborn
Nolo contendere.I think my opening statement (BTW: I thought you’d like it) also covers the authors conflation of different RE namings.
-
Coming in late, but I was searching for a way to do something similar “from the command line”.
I have a utility that greps through DB-based data. It lists hits, and if a user chooses one, write the corresponding content to a temp file and opens it up in Notepad++. However, to FIND data from that point, the use has to open the find dialog and type in the text again and press go.
I’d love to find a way to pre-search, JUST the file opened from the command line, for a specific text string. Have the matching strings already found, highlighted and the cursor on the first match.

Filelocator Lite, which is now known as AgentRansack, is what I’m using. Npp is great, however there is a flaw that can force me to delete it.
-
you can do it without notepad https://stackoverflow.com/a/20999154/12517370
-
I’d like to use such a feature so that I can integrate with a browser extension that can ask Notepad++ to open the given html file (at rightclick or icon in toolbar) and edit it.
Having the feature discussed here would allow me to first select a piece of text, then have Notepad open the html exactly where that is. -
If your browser extension knows the line number of the selected text, then you could use the -n command line option to tell Notepad++ which line to scroll to. You don’t need to be able to “find in files” from the command line to implement that behavior.

update: @artie-finkelstein actually pointed out-nin September 2021, though you may not have waded through enough of the posts to notice it, nor maybe understood the implication that it could solve your problem easier than “find-in-files-from-command-line”. -
