Command-line options for 256 color for opacity in nstars #2

Closed livibetter closed 7 years ago

livibetter commented 7 years ago

I noticed that ncurses is only one does not utilize the opacity, my guess is about the standard 16-color.

Can we add option parsing and allow to turn on 256 color support? IIRC, it has 24 gray gradient. I also prefer the "." (period) over "*" (asterisk), it looks more consistent with other frontends, so with options, user can override the character (may also want to work to support Unicode).

I can help with this, but maybe you would prefer to implement by yourself if you think this is a good feature. It might also be a good idea to add options support to the other two, even without any options.

I appreciate the interest in the project!

For me, the ncurses front end was mostly a study in basic ncurses and the silly IRC-like command interface at the bottom. I don't actually mind what character represents a star. My choice of asterisk was more due to it appearing closer to the center of the line than the period.

Pull requests are appreciated :-)

Either way, feel free to submit a PR changing the character. Maybe if you're up to it, you could also add a /char x command to be able to change it as the program is running too! shouldn't be that hard.

I did not attempt to experiment with color here, but applying the opacity would be cool too.

It would be interesting to vary the character to the closest approximate to the star's sub-character position. This is the kind of thing aalib/libcaca does to render graphics in text, but I think stars may be a nicely simplified case where it wouldn't require much effort to get reasonable results.

@ph1l how silly me to forget there is the "silly IRC-like command interface" already in place. I was wondering why there is a command-line interface when there is only one command you can issue. Now it's very helpful. I will try to add two commands first, /char X and /colormode <mono|256>.

@vcaputo I think I need PR to see what you are talking about.

@livibetter Perhaps the aalib gallery will suffice http://aa-project.sourceforge.net/gallery/

Closing, this will be resolved in #6.
