Re: [NTG-context] Bug regarding placement and size of primes

Thank you very much for providing the instructions, Mikael! Unfortunately

1) get the files

svn checkout --username anonsvn --password anonsvn https://serveur-svn.lri.fr/svn/modhel/luatex/branches/experimental/ https://serveur-svn.lri.fr/svn/modhel/luatex/branches/experimental/ does not work on MacOS (which I am using). Can someone tell me which command I need to use at MacOS (current version)?

Besides, Hans, I think it is a questionable decision to include the new mechanism for primes in the beta but not the required LuaTeX version for them to work correctly. I tried out the ConTeXt version „current“ (--context=current downloading the standalone) and there the old bugs persist. That means that I cannot use ConTeXt to typeset mathematics now, since no version works correctly when primes are required (until I can handle it to compile LuaTeX 1.05, but I think it would be much more comfortable the beta version of ConTeXt could run using the LuaTeX version it provides on it’s own).

Hi Mikael,

when will LuaTeX 1.05 be released? And how can I get the source for compilation (and what exactly will I have to do to get everything to work)? Besides: Do you have a link to the thread you are referring to?

Dear Hans,

the newest beta (I have updated some hours ago) contains again some bugs regarding the size and placement of primes. You can verify that by using the following minimal example (created to show some older bugs being resolved meanwhile):

%%%%%%% \starttext % Compare $f'$ to $(f')$ and to $f''$, $(f'')$, $f^{''}$ and $(f^{''})$. % \startformula % \int\nolimits_a^b \bigl(\|f(x)\|\bigr)\, {\mathrm d}x % \stopformula % \stoptext %%%%%%%

The output is attached. The primes are obviously rendered too small. And while $f'$ seems to lead to a placement of the prime a little too low, $f^{'}$ seems to cause the prime being placed too high.

Best Mathias

I think this is intended (see the other thread). Hans decided to do the primes differently, which means that they will look strange until luatex 1.05 is out. You can compile luatex 1.05 yourself, and you will see that the primes look OK. I attach a pdf result of your file, compiled with 1.05.

As far as I understand 1.05 will be out at the same time as the context meeting takes place (Sepbember?).

For the thread, it was this one (that you participated in): https://mailman.ntg.nl/pipermail/ntg-context/2017/088747.html . I think the information you need is available there, but still:

I run linux (ubuntu), and these are the steps that made it work for me (with help of luigi and Taco):

1) get the files

svn checkout --username anonsvn --password anonsvn https://serveur-svn.lri.fr/svn/modhel/luatex/branches/experimental/

2) compile:

step into the folder experimental and run build.sh

3) copy the luatex binary to a place where it is found

I chose to replace the one from garden, and it seems to work.

Good luck!
