Examples

Define new conversion set

\defineconversion[inventory][<3,!,\math{\therefore},?]

Four are the things I'd been better without:
\startitemize[inventory, packed][stopper=, width=2em]
    \item Love,
    \item curiosity,
    \item freckles,
    \item and doubt.
\stopitemize
\leftaligned{---Dorothy Parker, \quote{Inventory} (fragment)}

Change numbering in itemize to '(i)', '(ii)', ...

\defineconversion[bracketroman][(\romannumerals]

Three be the things I shall never attain:
\startitemize[bracketroman, packed][stopper=), width=2em]
    \item Envy,
    \item content, and
    \item sufficient champagne.
\stopitemize
\leftaligned{---Dorothy Parker, \quote{Inventory} (fragment)}

Conversion set of stars

\defineconversion[starred][\m{*},\m{**},\m{***}] % Math mode gives better spacing, thus \m{...}

\startitemize[starred,packed][stopper=,width=2.5em]
    \item First,
    \item second,
    \item third.
\stopitemize

Conversion for numbers with leading zeros

\startluacode
interfaces.implement {
    name      = "FourDigits",
    public    = true,
    arguments = "string",
    actions   = function(s) context("%04d",tonumber(s)) end
}
\stopluacode

\defineconversion [FourDigits] [\FourDigits]

\setuphead[chapter][conversion=FourDigits]

\startchapter [title={Chapter}] \stopchapter
