Flushleft formula

Flushleft formula

Hi,

Something has changed with respect to the align=flushleft option for 
formulas. Earlier (tested with 2016.05.08), align=flushleft did not remove 
the leftskip, but now it does.

Consider the following example:

\showframe
\setupitemize[margin=6em]
\setupformula[align=flushleft]

\starttext
\startitemize
   \item An equation inside an itemize
     \startformula
       E = mc^2
     \stopformula
\stopitemize
\stoptext

The output of 2016.05.06 is attached as test-old.pdf; that of 2016.06.16 
is attached as test-new.pdf

Is it possible to revert to the old behavior?

Thanks,
Aditya

it doesn't but somehow it's not effective

(indeed spacing was updated, some more - future - possibilities and 
bester handling in boxes and such)

can you test with

    \hskip\d_strc_formulas_display_margin_left % was kern but that 
doesn't indent

line 1153 in math-ali.mkiv

And some stage, it will be nice to discuss the possiblility of adding 
background to formulas, especially aligned formulas. Similar to some of 
the examples in 
http://texdoc.net/texmf-dist/doc/latex/mathtools/empheq.pdf

I guess you already added it to the new beta. It works correctly.

Thanks,

something like a

\setupformula
  [before={\startframedtext[background=color,backgroundcolor=lightblue]},
   after={\stopframedtext}]

?

("untested")

One typically wants to have a bounding box around the displayed math, but 
not the white space or the equation number. For example, see the attached 
image.

actually, backgrounds were a reason for some changes but the code that 
does that is not yet integrated (still considering the interface)

experimental framed support in beta ...

\starttext

\setupformulaframed[framecolor=red,frame=on,offset=1ex]
\setupformula[option=frame,color=blue]
\setupformula[numbercommand={\inframed[framecolor=green]}]

\startplaceformula
     \startformula
         2 + 2 = 3 + 1
     \stopformula
\stopplaceformula

\stoptext

see framed-002.tex in test suite for a bunch of examples

(rather tricky with respect to spacing and alignments etc)
