import { conceallevel } from "https://deno.land/x/denops_std@v4.1.4/option/mod.ts";
{not available when compiled without the |+conceal| feature} Determine how text with the "conceal" syntax attribute |:syn-conceal| is shown:
Value Effect ~ 0 Text is shown normally 1 Each block of concealed text is replaced with one character. If the syntax item does not have a custom replacement character defined (see |:syn-cchar|) the character defined in 'listchars' is used (default is a space). It is highlighted with the "Conceal" highlight group. 2 Concealed text is completely hidden unless it has a custom replacement character defined (see |:syn-cchar|). 3 Concealed text is completely hidden.
Note: in the cursor line concealed text is not hidden, so that you can edit and copy the text. This can be changed with the 'concealcursor' option.
