kandi X-RAY | pire Summary
This is PIRE, Perl Incompatible Regular Expressions library. This library is aimed at checking a huge amount of text against relatively many regular expressions. Roughly speaking, it can just check whether given text maches the certain regexp, but can do it really fast (more than 400 MB/s on our hardware is common). Even more, multiple regexps can be combined together, giving capability to check the text against apx.10 regexps in a single pass (and mantaining the same speed). Since Pire examines each character only once, without any lookaheads or rollbacks, spending about five machine instructions per each character, it can be used even in realtime tasks. On the other hand, Pire has very limited functionality (compared to other regexp libraries). Pire does not have any Perlish conditional regexps, lookaheads & backtrackings, greedy/nongreedy matches; neither has it any capturing facilities. Pire was developed in Yandex (as a part of its web crawler. More information can be found in README.ru (in Russian), which is yet to be translated. Please report bugs to dprokoptsev@yandex-team.ru or davenger@yandex-team.ru.

How to remove this warning I have this function in my code and showing the following warning !! Does my code work in same way if i remove -?
...ANSWER
Answered 2021-Mar-18 at 03:53You can use ESLint's no-useless-escape
rule, which will suppress warnings when you use escape characters that don't change the string's meaning. Also see this question and its answers.
As a bit of extra info, -
in a regex only has special meaning if it's inside of square brackets [ ]
and otherwise does not need to be escaped. None of the instances in your regex appear to be inside such brackets, so it's safe to say the regex will work the same if you do decide to just remove the escape characters.
QUESTION
I am trying to draw 2D metaballs using WebGL2. I render a bunch of quads with transparent radial gradient and gl.blendFunc(gl.SRC_ALPHA, gl.ONE_MINUS_SRC_ALPHA)
to a separate framebuffer. I then use the resulting texture in a fullscreen quad, where I decide if pixel should be rendered based on it's alpha value like so:
ANSWER
Answered 2021-Jan-03 at 15:45I'm pretty sure the issue the texture your rendering to is 8bits. Switch it to a floating point texture (RGBA32F
) You'll need to check for and enable EXT_color_buffer_float
and OES_texture_float_linear
You say it won't work on mobile but you're using WebGL2 which hasn't shipped on iPhone yet (2021/1/3). As for RGBA32F not being renderable on mobile you could try RGBA16F. You'll have to check for and enable the corresponding extensions, EXT_color_buffer_half_float
and OES_texture_half_float_linear
. Your current code is not checking that the extensions actually exist (I'm assuming that was just to keep the code minimal)
The corruption is that your circle calculation draws alpha < 0 outside the circle but inside the quad. Before that was getting clipped to 0 because of the texture format but now with floating point textures it's not so it affects other circles.
Either discard
if c
<= 0 or clamp so it doesn't go below 0.
Note: you might find coloring faster and more flexible using a ramp texture. example, example2
Also note: It would have been nice if you'd created a more minimal repo. There's no need for the animation to show either issue
Update 2Something else to point out, maybe you already knew this, but, the circle calculation
QUESTION
I want to compare the output of a scalar function with a scalar value in a CHECK statement when creating a table, but it doesn't seem to do the right comparisons. I want the check statement to be "checked" if the scalar function returns 1. Is there any way to do this? (The function is called in the last check statement)
The statement runs successfully, and if I run the function out of the CHECK function it returns the right values (0 or 1), but when I insert data that satisfies 1 in the function returned value, errors are returned. This is my code and what I've tried,
...ANSWER
Answered 2020-Dec-01 at 00:44Marx,
I see no error with the CHECK statement in your table. See the dbfiddle here; it is working as intended, because the value you are trying to INSERT violates the CHECK statement and will not work.
If you click the link and scroll down, you see that based on the data you provided, there is no way for the function to return 1 for some of these rows. Namely, here is one example that fails:

Remove all the external script tags and css files from the html partials, or use a different method to include the html partials.
Also, those partials don't need to have or tags, best case scenario they get ignored, worse case, they affect the way that the browser reads the document and creates unexpected behavior.
