' undefined inside \startformula .. \stopformula

' undefined inside \startformula .. \stopformula

[Sanjoy Mahajan]

I just noticed this test file failing:

\starttext
$f'(x)$
\startformula
f^\prime(x)\quad f'(x)
\stopformula
\stoptext

It gives:

! Undefined control sequence.
l.4 f^\prime(x)\quad f'
                       (x)

As you can see from lack of complaint about $f'(x)$, the ' still works
in inline math mode.  So somehow the ' active charcode setting didn't
make it into display-math mode?

I couldn't get any tests to produce a PDF file on the live context, so I
didn't test it there.  But I'm using:

ConTeXt  ver: 2006.12.20 23:52 MK II  fmt: 2006.12.25

This is a typo in math-pln.tex. The end of the file should be

\bgroup
     \catcode`\_ = 13
     \catcode`\' = 13
     \doglobal\appendtoks
         \let_\activemathunderscore

Hi Aditya,

I've copied your codes and replaced the original ones with them, but I
failed when I make the formats:
texexec --make --all

It gives me the following message:

Sorry, about that. This is because of the loading order of files. For 
the time being, you can copy the definitions to cont-new.tex or to the 
top of your tex file.

Hans, what is the proper way of getting this to work. Also append to 
\everydisplay, or move the definitions to core-mat? (Or I am 
completely missing the point?)

such temp hacks go into cont-new indeed and when ok can go into a core 
module

everymathematics covers both inline and display math

ok, fixed ... the _ thing is kind of weird and taco and i could not cook 
up a reason why plain does/needs that ; the ' (prime) is needed

this trickery is related to a change in the catcode management of 
context (which interferes with some plain tex left-overs)

Hans has uploaded a new version, with fix (context 2006.12.27).

Just tested on my test file and it works.  Thanks to all,
