Re: [NTG-context] ! Declared variable conflicts with previous vardef [Metapost]
z is a MetaPost intrinsic, something along the lines of vardef z@#=(x@#,y@#) enddef; so you can't use the same name for a pair. Actually you can simply delete the declaration pair z[]; from your file and it will work as intended. If you insist on using your own declaration of z, then you have to stash away MetaPost's definition using save z; pair z[]; I recommend the former, just delete pair z[]; On 3/01/19 2:43 PM, Fabrice Couvreur wrote: > Hi, > I have a problem compiling this file. > Thanks. > Fabrice > > ## test file > \starttext > \setupbodyfont [pagella,9pt] > \startMPpage[offset=2pt] > path p, q, r, b ; pair z[]; > p := unitsquare xyscaled (9cm,5cm) ; > z[0] = (2cm,0cm) ; > z[1] = (2cm,2cm) ; > z[2] = (0cm,2cm) ; > q := llcorner p--z[0]--z[1]--z[2]--cycle ; > r := unitsquare xyscaled (7cm,3cm) shifted(2cm,2cm) ; > b := z[2]--z[1]--ulcorner r--urcorner p--lrcorner r--z[1]--z[0]--llcorner > p--cycle ; > draw p ; > draw b numberstriped (.25,15,5) withcolor magenta ; > label.llft("A", p) ; > label.lrt("D", p) ; > label.ulft("C", p) ; > label.urt("B", p) ; > label.lft("M", z[2]) ; > label.ulft("N", z[1]) ; > label.bot("P", z[0]) ; > label.top("J", ulcorner r) ; > label.rt("I", lrcorner r) ; > label.bot(btex $x$ etex,(llcorner p+z[0])/2); > label.lft(btex $x$ etex,(llcorner p+z[2])/2); > \stopMPpage > > \stoptext > # > !
