Spacing between formula and texts
![](https://secure.gravatar.com/avatar/117a058bed6945e7fa1b40ff2f6e7aa7.jpg?s=120&d=mm&r=g)
Hi, I happened to review the output of my article and found one thing which is not perfect for me. The spacing between a formula and its upper texts is not treated well when I tuned with some indent things. Here is my test file ======================================== \usemodule[units] \setupindenting[big] \indenting[always,next] % no, not, yes, always, never, first, next % \setupformulas[spacebefore=5em] \starttext Blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, I love the following formula: \placeformula[-] \startformula 6.670 \times 10^{-11} \Newton \Times \Square \Meter \Per \Square \Kilo \Gram \stopformula which is very cool. which is very cool. which is very cool. which is very cool. which is very cool. % \showmathcharacters \stoptext ======================================== I'm really uncomfortable with that, and I want to solve it by myself. When I looked up the indent macros in core-spa.tex, how complex is that. So I just hope you guys could help me. -- Best Regards Chen ---------------------------------------------------------------- Zhi-chu Chen | Shanghai Synchrotron Radiation Facility No. 2019 | Jialuo Rd. | Jiading | Shanghai | P.R.

Hi Chen, I can't give a real solution but only a workaround, the problem lies in the macro \beforedisplayspace which calls \docomplexdoblank which calls itself \presetindentation and this macro causes your real problem. You solve this now by placing \let\presetindentation\relax at the begin in your document or remove the next key for \setupindenting. This is all what I can do for you in a few minutes, the rest is up to Hans to make a extra test in \beforedisplay or somewhere else to disable \preetindentation before a display formula. Wolfgang

Really! It works fine with "first" key. OK, I can just live with that, although I hope Hans will have time to fix it, it's not so cool with the first paragraph indented :) This is all what I can do for you in a few minutes, the rest is up to
Hans to make a extra test in \beforedisplay or somewhere else to disable \preetindentation before a display formula.

Hi Chen, you use the following code for the moment (untested): \newif\ifquicksolution \quicksolutiontrue \def\beforedisplayspace {\doifnot{\formulaparameter\c!spacebefore}\v!none {\quicksolutionfalse\blank[\formulaparameter\c!spacebefore]}} \def\afterdisplayspace {\doifnot{\formulaparameter\c!spaceafter }\v!none {\blank[\formulaparameter\c!spaceafter ]\quicksolutiontrue}} \def\presetindentation {\doifoutervmode{\ifindentfirstparagraph\else\ifquicksolution\noindentation\fi\fi}} Wolfgang
