Export image with current shell's theme

[fdncred]

This is from to png

This is from ls in the terminal

You'll notice other problems between these images too. to png looks good but it's not quite right. It's really noticeable on the header and footer labels as well as the row indexes.

will fix colors after patching the ansi parser

[FMotalleb]

added a new feature and flag --theme (-t) with two options (currently), vscode(default) and xterm
maybe ill add custom configuration

samples:

Vscode:

Xterm:

The improved functionality now includes compatibility with a variety of themes such as “vscode,” “xterm,” “ubuntu,” “eclipse,” “mirc,” “putty,” “winxp,” “terminal,” “win10,” and “win_power-shell.” Additionally, there’s flexibility to personalize each color within any chosen theme. This is achieved by using the custom-theme- prefix followed by the color name (for example, fg, bg, white, etc.). The custom-defined colors will take precedence, replacing the default colors of the selected theme.

I'm not really sure what the point of a theme is. I just want it to look like my screen. I'll try it out in a little while.

[FMotalleb]

I get your point; however, since the plugins API doesn’t grant me the capability to get your existing shell theme, this method allows you to customize the output to your preference.

[fdncred]

I understand now. I do think there's a way to query the terminal and get colors. I've seen it somewhere but maybe not all terminals support it.

I wrote this little thing tonight. It doesn't work perfectly because someone broke the input command but if you run this custom command and hit enter 16 times, and your terminal supports this query, you'll get an output like this below. At least this is how it works on Wezterm on MacOS.

I'll try to make it work but I don't think i can because of how stdin/out are controlled in nu-plugins

[fdncred]

I tweaked this conversion a little bit so it's a little more accurate with converting 16bits to 8bits.
