| Summary | 0000621: Actual mathstyle differs from \mathstyle after \mathchoice | ||||
| Description | If the mathstyle is altered directly inside a \mathchoice, the new style is still active after the mathchoice. However, the \mathstyle command expands to the style that was active before the mathchoice. | ||||
| Steps To Reproduce | Plain example: \def\1{\;a^a\mathstyle\;} $$ \1 \mathchoice{\scriptstyle\1}{}{}{} \1 $$ \bye The third part is typeset in scriptstyle, but reads a^a0. | ||||
| Additional Information | BTW, is there a reason why \mathchoice is not an integer parameter? | ||||

|
the last question should read: BTW, is there a reason why *\mathstyle* is not an integer parameter? |
|
|
To answer the last question: because it is read-only. |
|
|
I think it would be more consistent to turn \mathstyle into a read-only integer parameter like \lastpenalty or \inputlineno. |
|
|
one can use grouping ... it's mostly a scanner issue as the choice scanner doesn't restore the math style as seen during scanning .. changing that now is asking for compatibility problems \def\1{a^a[\mathstyle]} $$ \1 {\mathchoice{\scriptstyle(\1)}{}{}{}} \1 \mathchoice{\scriptstyle<\1>}{}{}{} \1 $$ we can decide to add an option to restore the style after scanning choinces by default |
|
|
will be explained in manual ... behaviour is as expected |
