Highlighting on One Dark theme

[wail-shudar]

The highlighting is dark on the One Dark theme. I attempted to edit the CSS file in Devtools. However I am unable to save the changes. Any help would be appreciated.

.ace_marker-layer .ace_selection {
    background: #996bbb;
}

The easiest way to tweak the theme would be to copy the one-dark.rstheme from the package, change the lines you want, give it a new name, and then install your new tweaked theme.

one_dark_pkg <- system.file("themes", "one-dark.rstheme", package = "rsthemes")
file.copy(one_dark_pkg, "my-one-dark.rstheme")
file.edit("my-one-dark.rstheme")
# change the first line to something like /* rs-theme-name: One Dark {mine} */
# tweak the CSS you want in the file and save
rstudioapi::addTheme("my-one-dark.rstheme", apply = TRUE)
