The following compiles correctly on live.contextgarden.net \starttext \startformula \startalign[n=3] \NC a \NC b \NC d \NR \NC a \NC b \NC d \NR \stopalign \stopformula in conjunction with \placeformula[eqn1] \startformula a = b \stopformula See \in[eqn1] \unknown \stoptext See if this works for you.

Try \def\ShowExample{\typebuffer\showbuffer} and if that does not work, I guess you do not have permissions to write to a buffer. (This is all that I can make out from the error message). Try modifying texmf.cnf for the correct permissions. (Again, I am not sure which setting you need to modify). Otherwise try the attached file. I have replaced all \typebuffer\showbuffer by \starttyping ... \stoptyping buffer contents (vim regex rules). This also compiles on live.contextgarden.

This can be done by specifying the number of blocks in \type<<m=?>>. \starttyping \startformula \startalign[m=2] \NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR \stopalign \stopformula \stoptyping \startformula \startalign[m=2] \NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR \stopalign \stopformula The distance between the blocks can be increased by specifying (well you guessed it) \type<<distance>> in the parameters of align. \starttyping \startformula \startalign[m=2,distance=5em] \NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR \stopalign \stopformula \stoptyping \startformula \startalign[m=2,distance=5em] \NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR \stopalign \stopformula However, this block mode can be cumbersome to work with. You need to work with two formulas at the same time and this can be confusing. There is another alternative in \tex{startformulas} \starttyping \startformulas \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NR \stopalign \stopformula \startformula \startalign \NC d_1 u + e_1 v \NC = f_1 \NR \NC d_2 u + e_2 v \NC = f_2 \NR \stopalign \stopformula \stopformulas \stoptyping \startformulas \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NR \stopalign \stopformula \startformula \startalign \NC d_1 u + e_1 v \NC = f_1 \NR \NC d_2 u + e_2 v \NC = f_2 \NR \stopalign \stopformula \stopformulas More than two groups can also be placed. \starttyping \startformulas \dorecurse{5}{\startformula \startalign[n=3,align={middle,middle,middle}] \NC a \NC = \NC b \NR \NC 2a \NC = \NC 2b \NR \stopalign \stopformula} \stopformulas \stoptyping \startformulas \dorecurse{5}{\startformula \startalign[n=3,align={middle,middle,middle}] \NC a \NC = \NC b \NR \NC 2a \NC = \NC 2b \NR \stopalign \stopformula} \stopformulas \section{Equation Numbering and referring} To number multiline displays, two things need to be done. Write \tex{placeformula} before \tex{startformula} to {\em start up} equation numbering. To actually number the equations, you need to type \type{[+]} with each \tex{NR}. Going back to our basic example \starttyping \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+] \NC a_2 x + b_2 y \NC = c_2 \NR[+] \stopalign \stopformula \stoptyping \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+] \NC a_2 x + b_2 y \NC = c_2 \NR[+] \stopalign \stopformula If you only want to number a some specific equations, just add \type<<[+]>> to that equation only. Suppose in the above example, we want to only number the second equation. \starttyping \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NR[+] \stopalign \stopformula \stoptyping \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NR[+] \stopalign \stopformula Some more examples \unknown \starttyping \placeformula \startformula \startalign[n=3, align={right,middle,left}] \NC a_1 x + b_1 y \NC = c_1 \NC = d_1 u + e_1 v \NR[+] \NC a_2 x + b_2 y \NC = c_2 + c_3 \NC = d_2 u + e_2 v + f_1 w\NR \stopalign \stopformula \stoptyping \placeformula \startformula \startalign[n=3, align={right,middle,left}] \NC a_1 x + b_1 y \NC = c_1 \NC = d_1 u + e_1 v \NR[+] \NC a_2 x + b_2 y \NC = c_2 + c_3 \NC = d_2 u + e_2 v + f_1 w\NR \stopalign \stopformula \starttyping \placeformula \startformula \startalign[m=2] \NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR[+] \stopalign \stopformula \stoptyping \placeformula \startformula \startalign[m=2] \NC a_1 x + b_1 y \NC = c_1 \NC d_1 u + e_1 v \NC = f_1 \NR \NC a_2 x + b_2 y \NC = c_2 \NC d_2 u + e_2 v \NC = f_2 \NR[+] \stopalign \stopformula \starttyping \placeformula \startformulas \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+] \NC a_2 x + b_2 y \NC = c_2 \NR \stopalign \stopformula \startformula \startalign \NC d_1 u + e_1 v \NC = f_1 \NR \NC d_2 u + e_2 v \NC = f_2 \NR[+] \stopalign \stopformula \stopformulas \stoptyping \placeformula \startformulas \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[+] \NC a_2 x + b_2 y \NC = c_2 \NR \stopalign \stopformula \startformula \startalign \NC d_1 u + e_1 v \NC = f_1 \NR \NC d_2 u + e_2 v \NC = f_2 \NR[+] \stopalign \stopformula \stopformulas There is no fun numbering equations if can not refer to it. Well, referencing an equation is easy. Instead of the \type<<[+]>>, you can specify \type<<[eq:tag]>> and then refer to the equation using \type{\in[eq:tag]}. For example, \starttyping \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[eq:1] \NC a_2 x + b_2 y \NC = c_2 \NR[eq:2] \stopalign \stopformula As seen from (\in[eq:1]) and (\in[eq:2]), referring equations is straight forward. \stoptyping \placeformula \startformula \startalign \NC a_1 x + b_1 y \NC = c_1 \NR[eq:1] \NC a_2 x + b_2 y \NC = c_2 \NR[eq:2] \stopalign \stopformula As seen from (\in[eq:1]) and (\in[eq:2]), referring equations is straight forward. {\bf Note that you need to put the tag with the \tex{NR} and not with \tex{placeformula} (as is done with single line equations).} \section{Some Advanced Tips} Well, need to understand more myself before writing this. Write about \tex{setupalign}, \tex{definealign}. Give examples of defining \type<<gather>> and \type<<split>> environments. \stoptext [-- Attachment #3: Type: text/plain, Size: 139 bytes --] _______________________________________________ ntg-context mailing list ntg-context@ntg.nl http://www.ntg.nl/mailman/listinfo/ntg-context ^ permalink raw reply [flat|nested] 14+ messages in thread
