API
sliceAnsi(string, startSlice, endSlice?)
Columns are counted the same way as string-width.
[!NOTE] Tabs and other control characters take no columns. Replace tabs with spaces first if you need tab stops.
string
Type: string
String with ANSI escape codes. Like one styled by chalk.
startSlice
Type: number
Zero-based visible-column index at which to start the slice. Grapheme clusters (for example, emoji sequences and combining marks) are kept intact.
endSlice
Type: number
Zero-based visible-column index at which to end the slice.
If a full grapheme cluster would cross endSlice, it is excluded.
