Remove every row with a number less than 1000 up to the first delimiter

…happy that the marking is correct click on “Remove Bookmarked Lines” which is under Search, Bookmark, that removes those rows.

A quicker way to get this menu to appear is to click in the margin that contains the purple ball bookmarks, like so after the right-click:

Note the right-click point was after the 9 of line 9, directly between the two bookmark symbols. If you squint you can see that this margin is a slightly different shade of grey than the line number margin.

Unfortunately, this did not produce the output I desired, and I’m not sure why. Could you please help me understand what went wrong

I had a look at your solution and realised you made the mistake of using “meta-characters” where they don’t apply. I suggest reading the online manual for allowed “extended search” characters here. The [ and ] mean exactly that in extended mode, when used in “regular expression” mode they refer to a set that is contained within. And there was your second problem, each of the characters except for the - are tested individually. So in essence your set was numbers 1-9 (usually use 0-9), the 2 extra 9’s following were just a duplication of the preceding 9.

So your expression said find as many numbers which are using ONLY 1-9 (excludes the 0) together. See my example below to see what results in. The same result occurs when using [1-9]+.

I think you will find a mine of information if you go through the FAQ section of this forum. Specifically the regular expression detail in the post here.

Good on you for trying, we like to see someone who has at least attempted to find a solution before asking here. Many however think we are a free bus service, hop-on and off at will, and seem reluctant to learn anything.

the purple ball bookmarks

You say purple, I say blue!

Who is right? Of course if we get a “female” to intercede it’s likely to be “deep-sea-blue”, or “sky-purple”. Most men deal in 16 colours. Those old enough would remmebr the good old days when Windows 1.x provided 16 colour renditions of the GUI, WOW!

Purple

Blue!

Neither!

RGB(25 66 191) at the dark edge
RGB(141 159 226) at the bright spot

Well… the color of the ball (or is it a circle or a sphere, Terry? :-) ) is not uniform throughout its area, so I’m sure we’re both right and there are some definite blue pixels and some definite purple pixels – I’m not going to examine pixels but “blue” or “purple” might be arbitrated by comparison with website data that gives colors a name. Don’t laugh, colors get the scientific treatment just like everything else.

Hello, @eric-tilley, @terry-r, @peterjones, @alan-kilborn and All,

A bit, off topic but …

From this site :

http://mkweb.bcgsc.ca/colornames/color.names.txt

containing a list of 9,284 colors, taken from many sources ( Color-hexa, Crayola, Pantone, Resene, rgb.txt, Wikipedia, xkcd and few others ) and with the help of some regexes, I was able to determine that the colors provided by Peter, relative to the bookmark indicator, are quite similar to the two colors below :

Dark edge of boomarks ( from Peter)           |  025  066  191

       |  Index 6603  |  persian_blue         |  028  057  187  |  #1C39BB  |

Bright spot of bookmarks ( from Peter )       |  141  159  226

       |  Index 5194  |  light_sapphire_blue  |  139  162  231  |  #8BA2E7  |

In your browser, press Ctrl + F to perform a search and enter the index numbers 6603 and 5194, followed with a space char => You should move to the corresponding color. Of course, all these color’s names seem quite subjective, excepted the well-known main colors !

In my opinion, the N++ bookmark’s color seems more blue than purple or even turquoise, as suggested by the two names persian_blue and light_sapphire_blue ;-)

Anyway, don’t forget that, on average, 8.3 % of the mondial population is color blind, so… !

Best regards,

Somehow I just knew that @guy038 was going to weigh in on the topic of colors… :-)

I’m not knocking it, he’s just backed me up! BLUE wins! So Alan, now you HAVE to say blue circle/ball/sphere.

Cheers @guy038

When an ‘authoritative source’ ( @guy038 ) refers to another ‘authoritative source’ that in turn refers to xkcd as a source; you know that’s a well researched response. <grin> Guy, thank you, you made my day. And to top it all off, color.names.txt is a pretty cool reference to have on hand.

trigger warning: potential to confuse attempted humorous sarcasm with garden variety snark—
Note: I may have to take back some of my praise after I finally crawl back out of the seemingly bottomless hole of fascinating and unique information referenced on Mr. Krzywinski’s web site. Oh, the dangers of wandering outside one’s silo; education may be possible.

Internet tells me:

Color blindness (color vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world

So a random pair of women, compared to a random pair of men, are more than 10x likely to agree with obervations like “color X differs from color Y” in many cases. It makes sense that among women, more fine-grained descriptive terms would emerge that are sensible to them.

This is a nice instance of: “what was once a cultural trope is now a scientifically validated claim”.

That’s ridiculous, you.

are less then a tenth as likely to disagree

Better.

Hello @neil-schipper,

You quoted :

Color blindness (color vision deficiency, or CVD) affects approximately 1 in 12 men (8%) and 1 in 200 women in the world

So my proportion of 8.3 % was not correct. Giving your statement, this leads to a real proportion of 50 % × 1 ÷ 12 + 50 % × 1 ÷ 200. So the proportion of color-blind people, among the world population, is rather ≈ 4.4 %, with a clear proportion in men compared to women ( about 16 times more ! )
