Lua: Text Properties

[thobl]

The documentation of Attributes/Properties (https://ipe.otfried.org/ipelib/luaobj.html) does not seem to match the actual behavior.

Specifically, the following code works:

local text = ipe.Text(
   {horizontalalignment="hcenter", 
    verticalalignment="vcenter"},
   "some text", ipe.Vector(0, 0))
text:set("transformations", "affine")

Judging from the documentation, the following should have the same effect, but it does not set the transformations to affine.

local text = ipe.Text(
   {horizontalalignment="hcenter", 
    verticalalignment="vcenter", 
    transformations="affine"},
   "some text", ipe.Vector(0, 0))

Also, the names for the alignment attributes in the documentation are horizontalAlignment/verticalAlignment and not horizontalalignment/verticalalignment (the latter works, the former does not).

The attributes in the constructor reflect the environment set in Ipe when creating objects. Text is by default not transformable, even if everything else is - to make it transformable, you also need to set transformabletext. So the following should work:

local text = ipe.Text(
   {horizontalalignment="hcenter", 
    verticalalignment="vcenter", 
    transformabletext=true,
    transformations="affine"},
   "some text", ipe.Vector(0, 0))

I've fixed the misspelled attribute names in the documentation - thanks!
