PGF/TiKZ bug

I'm attempting to repost this correctly as a bug.

The PGF/TiKZ export option is missing closing } in some cases and losses the tick-marks on the y-axis.

The incorrect code generated by

[co]GeoGebra 5.0.352.0-3D (03 April 2017)

Java: 1.8.0_20

Codebase: file:/Applications/GeoGebra%205.app/Contents/Resources/Java/

OS: Mac OS X

Architecture: x86_64 / null

is

attached as is a hand-corrected version that will actually compile and

produce a reasonably correct version of the ggb screen.

• export for drawing axes is missing y-axis tick-marks because that line of code gives a point rather than a pair of points
• In

  textbook (from toolbar) in ggb using LaTeX, multiple lines of equations

  require an explicit \\ typed into the dialog box. When those lines of

  equations are exported in TiKZ/PGF a redundant \\ is added.

• When

  multiline LaTeX in a textbox (from the toolbar) is exported, the

  terminating $ setting off the equations as math inside the TiKZ/PGF node

  is inside the last } of the math expression and the entire node is

  lacking the closing }. (The last } on the line actually closes the

  parbox.) This last pair of errors is what causes the failure to

  compile. Sadly, it causes TiKZ/PGF to complain about subsequent \draw

  statements so it's a bit painful to debug, but that's not ggb's fault.

Well,

I tried attaching files, but I can't see that anything is happening.

There may be two copies of each, in which case the second errors file is

the real one. So I guess I'll just quote excerpts here.

y-axis is:

\draw[shift={(0,\y)},color=black] (-2pt,0pt) node[left] {\footnotesize $\y$};

y-axis should be:

\draw[shift={(0,\y)},color=black] (-2pt,0pt) -- (2pt,0pt) node[left] {\footnotesize $\y$};

a block of equations is:

\draw

(38.02668824248539,15.782488764428555) node[anchor=north west]

{\parbox{23.339053270351926 cm}{$\vec{F}_R=I\vec{L}\times\vec{B} \\ \\

\vec{F}_R=IHB(-\hat{y})\times(-\hat{z}) \\ \\ \vec{F}_R=IHB\hat{x$}};

the same block of equations should be:

\draw

(38.02668824248539,15.782488764428555) node[anchor=north west]

{\parbox{23.93081627089105 cm}{$\vec{F}_R=I\vec{L}\times\vec{B} \\

\vec{F}_R=IHB(-\hat{y})\times(-\hat{z}) \\ \vec{F}_R=IHB\hat{x}$}};

So

maybe it's the closing } on the final \hat that is missing, but the

other \hat instances have both {}. In any case, what is currently being

output doesn't work.
