unfortunately, these commands are in no book. I just looked them up in the ConTeXt source. However, these two books helped me a lot in improving my understanding of TeX and ConTeXt. They are definitely worth their money!
The TeXbook by Donald E. Knuth https://amzn.com/0201134489 Programming in Lua by Roberto Ierusalimschy https://amzn.com/859037985X Other good books for TeX are
- TeX by Topic (https://www.ctan.org/pkg/texbytopic) and - TeX for the Impatient (https://www.ctan.org/pkg/impatient)
the next upload (not today) will provide a specifier so that one can make helpers \starttext \showframe \setupformulas[align=flushleft] \startformula \startalign[m=2,align={middle}] \NC \text to 6cm{} \NC x = 0 \NR \stopalign \stopformula \startformula \startalign[m=2,align={middle}] \NC \text to 6cm{One\hfill} \NC a = 1 \NR \NC \text to 6cm{One Two\hfill} \NC b = 2 \NR \NC \text to 6cm{One Two Three\hfill} \NC c = 3 \NR \stopalign \stopformula \startformula \startalign[m=2,align={left}] \NC \text to 6cm{One\hfill} \NC a = 1 \NR \NC \text to 6cm{One Two\hfill} \NC b = 2 \NR \NC \text to 6cm{One Two Three\hfill} \NC c = 3 \NR \stopalign \stopformula \blank[3*big] \startformula \startalign[m=2,align={middle}] \NC \text to 6cm{} \NC x = 0 \NR \stopalign \stopformula \startformula \startalign[m=2,align={middle}] \NC \text to 6cm{One} \NC a = 1 \NR \NC \text to 6cm{One Two} \NC b = 2 \NR \NC \text to 6cm{One Two Three} \NC c = 3 \NR \stopalign \stopformula \startformula \startalign[m=2,align={left}] \NC \text to 6cm{One} \NC a = 1 \NR \NC \text to 6cm{One Two} \NC b = 2 \NR \NC \text to 6cm{One Two Three} \NC c = 3 \NR \stopalign \stopformula \blank[3*big] \startformula \startalign[m =2,align={middle}] \NC \text{} \NC x = 0 \NR \stopalign \stopformula \startformula \startalign[m=2,align={middle}] \NC \text{One} \NC a = 1 \NR \NC \text{One Two} \NC b = 2 \NR \NC \text{One Two Three} \NC c = 3 \NR \stopalign \stopformula \startformula \startalign[m=2,align={left}] \NC \text{One} \NC a = 1 \NR \NC \text{One Two} \NC b = 2 \NR \NC \text{One Two Three} \NC c = 3 \NR \stopalign \stopformula \stoptext ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
