Formula editor for KDE

The formula plugin for Calligra Words is not as handy as LibreOffice Math. I know the markup language used in LibreOffice Math fairly well. I wonder whether is it possible to edit formulae using text editor in LO Math's markup and save them as OpenDocument Formula files and then import them to Words or Stage (without installing LO Math).

I'm considering Calligra when I use KDE, and the formula editor is one major obstacle. Any suggestions? I'm willing to learn other markup languages like (La)TeX or MathML, if necessary.

I've never used KDE, but is it really so important to avoid GTK programs? I use Qt programs in MATE all the time and it doesn't cause any problems. Does the other way around not work as well?

It works.

It doesn't definitely matter. I occasionally use Qt-based programs on Gnome, Cinnamon or MATE, too.

Another concern is that LibreOffice Math saves formulae in either ODF formula format (*.odf) or MathML 2.0 format (*.mml). The former is binary but the latter is a text file format. I prefer text files so I wonder whether I can directly write formulae in markup using a text editor like Emacs of Nano.

Note: It seems that there is no "Flat ODF Formula" (*.fodf) format in LibreOffice Math.

You can... but MathML is an XML format and typing XML is tiresome: far too verbose! You should learn LaTeX. You can do so adapting existing documents.

I see. When I create a simple "E=mc^2" and save it as MathML, I got this:

<?xml version="1.0" encoding="UTF-8"?>

E
=

mc
2

E=mc^2

LaTeX seems to be somehow similar to LibreOffice Math's markup, but even shorter. Maybe I can try Kile under KDE.

You can type LaTeX in your favorite text editor.
