[Solved] Newline and brackets

[McLP]

I want to make a formula like

Code: Select all   Expand viewCollapse view

alignl ( (a and b or c) and newline alignl a or (c and d) )

, but it creates weird output.

the output created by the example code

I have a very long fomula that without using newline would not fit on the page. But the newline seems to confuse the brackets and operands. I tried with none and other tips from the forum, but they did not work with logical operands.

I need fast help, thank you!

Try this:

Code: Select all   Expand viewCollapse view

alignl { (a and b or c) and {} } newline  alignl { {} a or (c and d) }

{} : invisible empty operand

{ .... } : invisible grouping sign

You can't have grouping across newline. This is an annoying limitation of the Math component.

A workaround is to insert invisible group close at the end of the line, then invisibly start a new parenthesis group on the new line.
To use different tokens for group initiate and terminate, you need to use the "left" and "right" keywords.

Code: Select all   Expand viewCollapse view

alignl left ( (a and b or c) and {} right none newline left none alignl a or (c and d) right )

Thank you all for your help, I now switched to using LaTeX. But I can say that keme's workaround would work in OO too.
