shortvrb
‘s MakeShortVerb
allows defining single active tokens, e.g. |
, in a way that makes |foo|
equivalent to verb|foo|
. To do this, |
is defined to expand to verb|
and added to both dospecials
and @sanitize
. Internally, MakeShortVerb|
expands to def@shortvrbdef{verb}@MakeShortVerb|
and @shortvrbdef
is later used to set the expansion of |
.
I want to use the same mechanism but with minted
. In order to use the minted
macro code
(as defined in the MWE below) insead of verb
, I defined
defMakeShortCode{def@shortvrbdef{code}@MakeShortVerb}
However, I get the error
! Paragraph ended before minted@inline@ii was complete.
when using the shorthand. If I manually define
def|{code|}
the shorthand works fine. Inspection of the definition of |
in both cases shows that they are indeed identical, so the only difference should be the registration of |
in dospecials
and @sanitize
.
Why exactly does this error occur? How can I get around this without braking e.g. the verbatim
environment? Is this a bug in minted
or is there a good reason for this behavior?

The problem is that when code|foo|
is executed, TeX only scans for the second |
after dospecials
changed its category code to 12
. @MakeShortVerb
defines |
13 to expand to code
0|
13 (the indices denote category codes), so |foo|
effectively expands to code
0|
13foo
0|
12, which can't work.
We can fix this by modifying MakeShortCode
to define |
13 as code
0|
12.

Not sure why trying to overcomplicate things:
documentclass{article}
usepackage{minted}
newmintinline[code]{latex}{}
catcode`|=active
makeatletter
protecteddef|{%
ifmmode
expandafter@firstoftwo
else
expandafter@secondoftwo
fi
{string|}{code|}%
}
makeatother
begin{document}
|foo|
$|a+b|$
end{document}
A more complicated version that allows to locally remove a shorthand.
documentclass{article}
usepackage{minted}
newmintinline[code]{latex}{}
makeatletter
newcommand{makemintedshorthand}[1]{%
expandafterchardefcsname catcode#1endcsname=catcode`#1
begingrouplccode`~=`#1lowercase{endgroup
protecteddef~{%
ifmmode
expandafter@secondoftwo
else
expandafter@firstoftwo
fi
{code~}{#1}%
}}%
catcode`#1=active
}
newcommand{removemintedshorthand}[1]{%
ifcsname catcodestring#1endcsname
catcode`#1=csname catcodestring#1endcsname
fi
}
makeatother
makemintedshorthand{|}
begin{document}
|foo|
$|a+b|$
begingroup
removemintedshorthand{|}
code$abc|def$ code|abc$def|
verb|xyz| verb"a|b"
endgroup
|foo|
end{document}
