about selection

Alan Kilborn

Probably the best way for anyone to help you, is to help us by answering @Ekopalypse 's questions that you’ve so far largely ignored:

May I ask you what you want to do with the selection?
I mean, it doesn’t make sense to select the lines only, obviously you
want to do something with it, won’t you?

Given that we don’t know your real plans for these selections, might I suggest, after you’ve gotten your desired lines bookmarked, to copy them to a new file and continue working with them there?

yes. reverse line plug-in not work correctly with multiple selection…
anyway have solution to select all bookmark?
or select all line excluded some line with ### symbol?

Hi @cisco779k, All

Yes, it is possible to select all lines separated by hash symbols ( ### ) with a S/R regex, like the following:

Search: (?s)(?<=###\v\v).*?(?=\v\v###)
Replace: [leave empty]

Maybe I’m completely wrong, but I guess you want to use the reverse line plugin to flip lines locally —that is, reverse all the lines between hashes and only those— and don’t want to run a global reverse operation. I mean this (lines truncated for displaying reasons):

pacecececrst$$$!                   pacecececrst$$$!
###                                ###

If this is the outcome you want, I think is doable, though a bit complex. Anyway, if you can illustrate your needs with some examples it will be greatly appreciated.

yes Alan, right advice, that’s what i did!
i have solved with this: on reg-ex i have use this (?!^.###.$)^.+
with mark function to bookmark ALL line which do NOT contain ### (and this was something , wanted), then i have copy into new txt and used reverse line plugin to end my job.

@ astrosofista
you understand what I want to do. and although I have solved it, I want to understand for other jobs…
then, your reg-ex menthioned above work fine, but this work to FIND fields, it is not a selection!
we leave out the second part, which you have perfectly understood, but I have already solved, how to have real selection of my text included into ### symbol?

cisco779k

i’ve write my post above 5 hours ago. now i want edit, but is not possible… i must wait 3 minute after edit my post! the site must have something that doesn’t work well …
anyway: @ astrosofista keep my bad post above; your regex work fine and with mark all each field between ### is selected with bookmarks.
I was interested in this. Thank you for your contribution!

Correct; basically you have 3 minutes to edit a post. After that, you just create a new post with new information, or revise old information by discussing it in that new post.

cisco779k

ah ok! thanks for the clarification!

Great, it’s good to hear that the regex worked fine :)

Just in case you still need it, here it goes another regex, but this one only selects the hashes ###, so it does the opposite of the one posted yesterday. Click on Find Next to navigate through the file:

Search: (?s)[^#]+\R\K.*?(?=\R[^#])
Replace: [leave empty]

Best Regards

Alan Kilborn

@astrosofista :

It might be better to express regexes like this (inside of backticks) instead of the way you did it:

(?s)[^#]+\R\K.*?(?=\R[^#])

Whenever I see regexes with italics in them here, I think, uhoh, a * got consumed. Note that this is NOT the case for your posting (the regex is fine!), but the wacky italics and color is still “disturbing”.

Just a suggestion.

cisco779k

tanxs to both of them for your reg-ex.
however i don’t understand why to use reg-ex when on this simple case just enter in search field (or mark) ### …

@astrosofista said in about selection:

Also, your choice of terminology here (“selects”) probably only confuses the OP. Probably the word “finds” would have been the better way to go. :-)

cisco779k

no confusion. my initial intent (clearly expressed) was a selection of the text from the ### fields.
but since this selection is not possible, then i use the mark to make a copy & paste.

astrosofista

@Alan-Kilborn

Now I see —aging eyes here—, thank you, didn’t noticed till now that italics being applied after the * — maybe we need an escape character for avoid that, ha ha.

OTOH, I like the message structure or disposition, were the regex is on its own line.

Well, will see what can I do.

astrosofista

@cisco779k

Three reasons I can think of:

Error prevention. Regex provides more control than the normal mode, so I can make sure to only match what it is needed —as I haven’t checked the actual file and as I only had seen a sample—, I don’t know if those three hashes are also located in the middle of the file.
More error prevention. Regex also provides a way to override options that the user inadvertently may have checked. Thus, in the last regex (?s) forces the regex to run a multiline search.
Personal habit. In my Notepad++ the regex mode is always checked, so my first attempt is to run even simple searches in that mode. I only select the normal mode in order to avoid regex metacharacters intrusion — and get back to regex realm as soon as possible :)

Or you could just stay permanently in the regex realm (Search mode = Regular expression) and just lead off any “normal” searches you need to do (because of metacharacters) with a quick \Q – no need to bother with a trailing \E ! :-)

You can’t do a Whole word search this way, though, if you ever use that option, because that checkbox is disabled (but you could go to the trouble of adding \b before the \Q and at the other end).

I think maybe we have a misunderstanding. Your regexes in this thread are fine, I was just suggesting

this method

instead of

this method

because the second method does some lexing (does it think it is C++ above because it has special highlighting for “this”?) and the first method just leaves everything alone (and thus is probably clearer).

@Alan-Kilborn said in about selection:

Oh, yes. I thought you were suggesting inline regexes —that is, regular expressions in the middle of a paragraph—, which I really found confusing unless the expression is limited to a few characters.

So it´s clearer now. I will preserve the message structure while avoiding the multicolored format.

astrosofista

@Alan-Kilborn said in about selection:

Hmm, it looks very interesting. Will check the documentation, thank you.

Concerning the whole word issue, it wouldn’t necessarily be a problem. Because the Matching Brace feature is not available in the Find panel, a tool that I find almost indispensable to handle complex regexes, and both the Search and Replace fields are really short and the font size is too small for my needs, I usually write expressions on the Editor and use hotkeys to import and export them, so adding one or two options may not represent much trouble.

But let me first read about it and see if I can adapted it to my ways.

Hello, @cisco779k, @alan-kilborn, @astrosofista, and All

Of course, you certainly know that, in order to insert a code block, you must use, either the syntaxes :

```
Code_Text
```

or

~~~
Code_Text
~~~

But, do you know that you can add an indication, after the opening ``` or ~~~, to force a nice visual aspect of a specific language ?

Indeed, for example, you may use ```c to display a C code block, ```xml to visualize an XML piece of code and ```py to show a nice python script !

And to get only a black foreground text, with a white background, simply use any invalid indication. I usually write the ```z syntax !

Here are, below, the different indications that I’ve found out, yet, from the language names and extensions used :

    •---------------•--------------•---------------•
    |   LANGUAGE    |  MAIN form   |  OTHER forms  |
    •---------------•--------------•---------------•
    |  bash         |  sh          |  bash         |
    |  c            |  c           |  h            |
    |  c++          |  cpp         |  hpp          |
    |  c#           |  cs          |               |
    |  CSS          |  css         |               |
    |  DIFF         |  diff        |  patch        |
    |  HTML         |  html        |  xhtml        |
    |  HTTP         |  http        |  https        |
    |  ini file     |  ini         |               |
    |  javaScript   |  js / jsx    |  java         |
    |  JSON         |  json        |               |
    |               |  jsp         |               |
    |  Makefile     |  mk / mak    |  makefile     |
    |  Objective-C  |  mm          |  objectivec   |
    |  Perl         |  pl / pm     |  perl         |
    |  php          |  php         |  php3 / php4  |
    |  Python       |  py          |  python       |
    |  Ruby         |  rb          |  ruby         |
    |  SQL          |  sql         |               |
    |  XML          |  xml         |  xsl          |
    •---------------•--------------•---------------•

Note that I’m not sure, exactly, to which languages ( Java, JavaScript (embedded), JavaScript ) refer the indications js and jsp !?

I usually write the ```z syntax

I always wondered why the z was included, and sometime between last year and now, I had dropped the z to become just ``` alone. Now that I know the purpose of the z (and the other options), I’ll have to start using those.

And if you use the </> button to fomat a block of text, you can still go back above and add in the option; for example, here I added pl to the ``` line after I generated it using </>.

my $default;
open my $fh, '>', 'out.txt' or die "Goodbye, cruel world: $!";
sub hehe { say "haha"; }
BEGIN {
    $default = Win32::Mechanize::NotepadPlusPlus::Notepad->_new();
}

yep, it properly highlights that. cool.

Hello, @cisco779k, @alan-kilborn, @astrosofista, @peterjones and All,

Oh…, I’m sorry ! I spoke a little too fast :-(( Peter, I did some tests, again, with your piece of Perl, a Python script, some HTML and C code and…, seemingly, as soon as you click on the </> icon and you paste the different pieces of code, NodeBB seems, each time, to detect correctly the language !?

Indeed, after I added the related indication, and used Ctrl + Z and Ctrl + Y, I did not be able to see any difference in the code !!

So, the table shown, in my previous post, is rather useless. The only interesting case would be if you would show for instance, a Perl script, with the Python syntax !

Could your confirm my tests ?

Cheers,

guy038
