Description makism 2009-09-24 19:49:53 UTC
When invoking layman with "-Lv" it crashes, or better an exception/error is thrown.
I tried to do a "-f" first, but nothing changed.

Reproducible: Always

Steps to Reproduce:
1. `layman -Lv`

Actual Results:  
Traceback (most recent call last):
  File "/usr/bin/layman", line 37, in <module>
  File "/usr/bin/layman", line 34, in main
  File "/usr/lib/python2.6/site-packages/layman/", line 498, in __init__
    result += i[1](config).run()
  File "/usr/lib/python2.6/site-packages/layman/", line 380, in run
    for i in self.rdb.list(self.config['verbose'], self.config['width']):
  File "/usr/lib/python2.6/site-packages/layman/", line 221, in list
    result.append((str(overlay), overlay.is_supported(),
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 307: ordinal not in range(128)

Expected Results:  
A complete listing with all available overlays and a description for each overlay.

Comment 1 Conway S. Smith 2009-10-09 18:57:57 UTC
I also encountered this.  I think the best fix for now is to fix layman's remote/global list of overlays w/ the attached patch.  Long rambling description below.

I found that it was being caused by the description for the multimedia overlay using Unicode U+2019 "RIGHT SINGLE QUOTATION MARK" for the apostrophe in "gentoo’s", which apparently str() in python-2.6 can't handle.  Editing /usr/lib64/python2.6/site-packages/layman/ & changing str(overlay) to unicode(overlay) gets it past the traceback makism posted, and it looks like it mostly works, except for a few funky issues I don't understand.

Just running "layman -vL" works fine, printing out all the info for all the overlays, including those after multimedia, but the Unicode U+2019 "RIGHT SINGLE QUOTATION MARK" somehow becomes Unicode U+00e2 "LATIN SMALL LETTER A WITH CIRCUMFLEX" - "gentoo’s" becomes "gentooâs".  Which is weird, but I could live with that.  But what's even weirder is that if stdout is redirected, as with "layman -vL | cat", it prints everything through the first line of multimedia's description, but when it hits the line w/ the Unicode character it dies like this:

* multimedia
* ~~~~~~~~~~
* Source  : git://
* Contact :
* Type    : Git; Priority: 50
* Description:
*   Repository for development of (mostly bleeding-edge)
*               multimedia packages for Gentoo Linux. This is the official overlay

    print self.maybe_color('green', '* ') + i
UnicodeEncodeError: 'ascii' codec can't encode character u'\u2019' in position 35: ordinal not in range(128)

I resolved that by editing /usr/lib64/python2.6/site-packages/layman/ from
    print self.maybe_color('green', '* ') + i
    print self.maybe_color('green', '* ') + i.encode('utf_8')

After which it works when redirecting stdout (but again with "gentoo’s" becoming "gentooâs").

But I don't think hacking layman to play well with unicode is the way to go right now, what with the python3 unicode->str stuff.  My attached patch for layman-global.txt makes it work w/ layman-1.2.3.  It replaces the unicode apostrophe w/ ascii, and changes multimedia's description's white-space/line-wrapping to be more in-line w/ the rest of the file.

Until it's applied on, users can apply it to their local cache (for me it was /usr/local/portage/layman/cache_65bd38402ac8431067b54904bd2ed2d1.xml), and run "layman -nLv".

This should be fixed now.  app-portage/layman-1.2.4-r2 comes with a backport of the fix: please try it out and re-open this bug if necessary.  Thanks for reporting!;a=commitdiff;h=a4ce3e5d2076528950155069999873a92b87833e
