Some colors aren't displayed correctly when spelled out. about vim-css-color

[ap]

I cannot reproduce this. If you move your cursor onto an incorrectly highlighted word and give this command,

:echo map(synstack(line('.'), col('.')), 'synIDattr(v:val, "name")')

… what is the output?

Which other color keywords does this affect? “Some” isn’t much help… 😄

Yeah it wasn't helpful was it? lol. Sorry, was in a rush.

One of the colors I've used is purple. It looks like the color isn't shown but when you enter the hex value of it, the color pops up. In regards to the output I get:

['cssDefinition', 'cssAttrRegion', 'BG800080']

Attached is a screenshot.

OK, so, that bit looks right. I guess we’ll have to play 20 questions; sorry for the bother.

1. What does :hi BG800080 say in that situation?
2. If you type #800080 instead of purple, what colour do you get?
3. What does :hi BGa020f0 say in that situation?

Np.

Answer to question 1:

Answer to questions 2 & 3:

Thing is after I typed #BG800080 then it worked as per the screenshot.

Now when I quit vim and made up a new .css stylesheet and typed the color in again, it didn't work again.

Is the output of :hi BG800080 different after you type #800080, once purple is highlighted correctly, compared to the output before?

[ap]

Yes it is. No need to show me, I found it. This is painfully stupid.

It’s a late effect of #16, itself long fixed in commit c8ae081. Once upon a time, the mapping of RGB values to 256-colour terminal palette indices was recalculated at every Vim startup. Then, at some point, to make startup faster, I dumped the results of the conversion and hardcoded them in the script. But I did this back when the mapper function had a simple stupid bug that completely broke many of its results. As a result I hardcoded a bunch of broken outputs into the script. Arrrrrrgghhh. Later I fixed the bug but did not recompute the indices, so they’ve stayed broken for another 2½ years.

There you go. Thank you for the report.

Cool. Glad to help out. Thanks for resolving the issue!
