Mrbob error in Plone 5.1

Plone Support Add-on Development

I'm trying to create a theme for a plone 5.1 website following the instructions in https://docs.plone.org/develop/addons/bobtemplates.plone/docs/intro.html and all I get is the following:

maguimar@maguimar-HP:/opt/plone/zeocluster/src$ sudo ../bin/mrbob -O plonetheme.cittaconf bobtemplates:plone_addon

In http://mastering-plone-5-development.readthedocs.io/en/latest/theming/theme-package.html
says that should appear this
> What kind of package would you like to create? Choose between 'Basic', 'Dexterity', and 'Theme'. [Basic]: Theme

but I only get

--> What kind of package would you like to create? Choose between 'Basic', 'Dexterity'. [Basic]:

so no Theme option, and beyond that, at the end give me
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 13: ordinal not in range(128)

In another document https://training.plone.org/5/theming/theme-package.html it says to use the mrbob as follow

maguimar@maguimar-HP:/opt/plone/zeocluster/src$ sudo ../bin/mrbob -O plonetheme.cittaconf as bobtemplates:plone_theme_package

In any way I get stuck and don't know how to get out of this. I'll be grateful for any help

Just use ASCII characters for all the questions and see if that helps ( so skip the ã and other 'spanish letters' )

3

I'm only using ascii characters

It looks like the error comes form line 303, which is:

question = six.u("--> %s [%s]: ") % (self.question, self.default)

you could insert try to insert

# -*- coding: utf-8 -*-

in the first line of configurator.py

If that does not work, try inserting

import pub; set_trace()

above that line 303 and start in debug mode ( bin/instance fg ) and try (in terminal):

bin/instance fg

self.question  (and hit enter)

self.default (and hit enter)

I finally solved the problem. I noted that when I run mrbob in Python 3.5 everything works well and I verify that if I run sys.getdefaultencoding() I get 'utf-8' but in python 2.7 the same command returns 'ascii', so I inserted the following lines before the line 301 in configurator.py

  • reload(sys)
  • sys.setdefaultencoding('UTF8')

Before I had inserted this two lines, when I run the command
mrbob -O ploneconf.theme bobtemplates:plone_theme_package

I got this error:

--> Theme name [Theme]: Plone Theme

UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 13: ordinal not in range(128)

After I had included the two mentioned lines everyting works well when I run

mrbob -O ploneconf.theme bobtemplates:plone_theme_package

i understand now, it's something like this old problem

I guess that it means that plonecli can only be used by people having ascii names (unless one uses the workaround in the issue) and using only ascii directory names. Plonecli is listed as Python 3 compatible but in the context of Plone, a Python 2 app for now, it's not exactly natural to try to install it using Python 3.

please try the current version of plonecli and bobtemplates.plone, there shouldn't be a problem with umlauts.
Pay attention to the changed call syntax of bobtemplates.plone if you are using it directly.
We are using it only in Python 2.7 for now, because Plone runs only on that anywhay for now.
