Hi Rob,

Hopefully it's just the ones related to the TextBox stimulus? This has a couple of extra dependencies that I haven't ironed out on the standalone installations yet. You can still create text using the standard text stimulus though. Were there others that don't work?

cheers,
Jon

Hi Rob,

I do not think this is a missing freetype library issue; last I checked that was working fine.

The issue you are reporting is fixed in the psychopy/psychopy master branch. Basically, on OSX, there is a .TTF file that is not actually TTF font file, but a text file listing the available font files. ;)  

To check if the source you have has the fix or not,  open the psychopy/visual/textbox/fontmanager.py file in your site-packages, and check that lines 145 - 153 are as follows:

                try:
                    face = Face(fp)
                    if monospace_only:
                        if face.is_fixed_width:
                            fi_list.append(self._createFontInfo(fp,face))
                    else:
                        fi_list.append(self._createFontInfo(fp,face))
                except FT_Exception, fte:
                    pass

If not, please try getting the textbox folder from psychopy/psychopy master and (after a backup up) replacing the folder that you have from the install with it. Does that fix the issue?

** Also note that the textbox demo's are broken on psychopy/psychopy master after all the visual demo's were changed from using .getX to .x for visual attributes. Textbox has not been updated to use properties, so the change needs to be reverted for these demo's. 

This is easy to do, in the textbox demo's where there is something like 

textbox.text = newtext

change that back to 

.setText(newtext)

 

and the text demo's will run fine again. 

I can not fix these issues and submit a pull request myself because my fork of psychopy has a lot of other changes that are not completed and I can not do a pull request on a specific file in my fork, only the whole fork it seems.

Sorry about all this.

Sol

More specifically about the demo lines that need to be reverted before they will run:

In demo /stimuli/textBoxStim/textbox_glyph_placement.py, line 81 need to be changed back to:

mouse_position.setText("%.3f,%.3f"%(mp[0],mp[1]))

In demo stimuli/textBoxStim/textstim_vs_textbox.py, line 68 needs to be reverted to:

        stim.setText(text)

Thanks again,

Sol

Hi Jon, Sol

yes everything else seems to be ok (i just wanted to show some students some cool stuff :-)

I'll look into those lines/files Sol and report back 

[Rob Stone]

some more info  lines 145....  in fontmanager.py

 

                  try:

                    face=Face(fp)

                    if monospace_only:

                        if face.is_fixed_width:

                            fi_list.append(self._createFontInfo(fp,face))

                    else:

                        fi_list.append(self._createFontInfo(fp,face))

                except Exception, e:

                    import traceback

                    traceback.print_exc()

                    return None

                    pass

 

will try and find the master and install etc  and report back

[Rob Stone]

so i eventually figured out how to get a copy of the master and installed the new textbox folder into visual and it all works fine :-)

interestingly (or not as i've no idea how this is all configured) inside my resources i have 3 copiers of visual (and other stuff!)

Users/rob/Desktop/coding/exp-gen/psychopy/PsychoPy2-1.803.app/Contents/Resources/lib/python2.7/

psycopy/, psychopy-1.80.03/,  and  psychopy-1.80.05/

as it has autoupdated. It uses the psycopy folder (i presume this is correct just a bit funky)

Cheers

Yes, exactly. It isn't pretty, but it works ;-)

Great; thanks for letting us know.
