Evaluate command: tdf#109338
Adds evaluate command.
It's visible from UI as a bracket.
Example: evaluate { {1} over {%sigma sqrt{2%pi} }func e^-{{(x-%mu)^2} over {2%sigma^2}} } from { -infinity } to { +infinity } = 0
In order to make the mathml part, several changes had to be mad:
- Allow mathml to correctly identify the math token for opperators
- Allow mathml to correctly identify the math token for fences
- Since improvements where made on token recognision, visitors to string can now be lighter ( removing long long switch )
- Improving the import / export to mathm
- LO says it mathml 2, but actually is something between 2 and 3
- Allowing mfenced ( mathml 2.0 ) to stayl 3 adding the missing data ( prefix and postfix )
- Be able to know if we are opening or closing brackets
- lrline and lrdline commands hidden on UI.
- They are they own open close
- If prefix and postfix are missing meaning of the expression may change, however that's the user problem.
- The problem resides in the fact that MS_VERTLINE is uses for lline and rline.
- The problem resides in the fact that MS_DVERTLINE is uses for ldline and rdline.
- Changing frac priority from 0 to 5, if not { frac 1 2 frac 1 2 } fails ( found while testing )
- The mathml testing was made with highter standars than qa tests, however there are no guarantees.
- Added xml tokens needed for math
- Added starmathdatabase. Will grow in the future.
The point is avoiding long lists and swtches inside code.
Added it command for hidden or implicit product ( like ⁢ in mathml ). Oppens path for tdf#66200. Note that about this issue there is only one line on the parser. The mathml implementation will be made later when LO will allow chars with &charname;.
