Installation

Install like any other patch. Go into the source directory of ST, and run the following command:

patch < ../st-undercurl-0.8.4-20210424.diff

Then build it:

make

For installation, you either use Make (recommended):

make install

And you're done!

Or any other method, but in this case, you HAVE to update the TermInfo database of your system, to let terminal programs (Like Vim and such) know that ST supports special underlines. You do this with the following command:

tic -sx st.info

Style

You can choose between three different curly underline styles:

Curly:

Spiky:

Capped:

To change the style, edit the config.def.h file, it looks like this:

// Available styles
#define UNDERCURL_CURLY 0
#define UNDERCURL_SPIKY 1
#define UNDERCURL_CAPPED 2
// Active style
#define UNDERCURL_STYLE UNDERCURL_CAPPED

Just modify UNDERCURL_STYLE to one of the three available styles.
