bug in \doifinset

bug in \doifinset

[Pablo Rodriguez]

Hi Hans,

the following sample:

    \starttext
    \startTEXpage[offset=1em]
    \doifinsetelse{i7}{i4, i5, i7}
        {yes}{no}
    \stopTEXpage
    \stoptext

outputs "yes" with latest from 2020.05.18 16:50, but "no" with latest
from 2020.05.25 23:39.

I think this may be a bug, since the sample above would only get "yes"
with { i7}.

Many thanks for your help,

Pablo

No spaces are allowed in these lists. Older versions of the command 
removed the spaces before the entries but the current version is stricter.

Many thanks for your reply, Wolfgang.

Without commas, lists are harder both to read and to write (at least, to
me).

Many thanks for your help,

what about

\starttext
\startTEXpage[offset=1em]
\doifinsetelse{i7}{%
i4,%
i5,%
i7,%
}
        {yes}{no}
\stopTEXpage
\stoptext

here seems to work.

The \doifinset etc. commands are used for internal checks when a key 
accepts multiple values with the same result and none of the existing 
mechanism has a space after the comma. As a result of this I saw no 
problem with this limitation and without a more detailed example from 
you there is no reason to change this.

As Luigi already has shown there are ways to format your code in a way 
to create readable lists, below is another one but in the end it depends 
on your use case.

%%%% begin example
\starttext

\startsetups [check]

     \doifelseinset
         {
             i7
         }
         {
             i4,
             i5,
             i7,
         }
         {yes}
         {no}

\stopsetups

\directsetup{check}

\stoptext
%%%% end example

Wolfgang

we can use the old one, so only the raw variants then ignore the space; 
best to be downward compatible, even if this was never the formal spec 
(more a side effect)

it's only 20% slower and internally we we often use the raw one

Many thanks for your reply, Luigi.

This is a better approach for me.

Many thanks for help,

Just in case it might be relevant.

I have been using \doifinsetelse for two months now.

Backwards compatibility is not an issue for me (after Luigi provided a
better approach to the issue)
