It appears that a `.join` or `.to_s` method is missing somewhere.

can you patch

r << ' ' + s.to_s

in line 736

(a pretty weird situation if that changed in ruby; on my system that patch is not needed; ruby version 1.8.6)

I use ruby 1.9.3p286 (2012-10-12 revision 37165) [i686-linux] and it does appear to be due to a change in the Array class. See http://stackoverflow.com/a/3960429/193149 http://nuclearsquid.com/writings/ruby-1-9-what-s-new-what-s-changed/ (search for to_s) The bug is not in line 736. If I change that line to r << ' ' (an extreme case always helps testing), I get texexec --help --all TeXExec | ["version 6.2.1 - 1997-2009 - PRAGMA ADE/POD"] TeXExec | ["--check check versions"] TeXExec | ["--figures generate overview of figures"] TeXExec | ["--listing list of file content"] TeXExec | ["--make make formats"] TeXExec | ["--modules generate module documentation"] TeXExec | ["--mpgraphic process mp file to stand-alone graphics"] TeXExec | ["--mpstatic process mp/ctx file to stand-alone graphics"] TeXExec | ["--mptex process mp file"] TeXExec | ["--mpxtex process mpx file"] TeXExec | ["--pdfarrange impose pages (booklets)"] TeXExec | ["--pdfcombine combine multiple pages"] TeXExec | ["--pdfcopy copy pages from file(s)"] TeXExec | ["--pdfselect select pages from file(s)"] TeXExec | ["--pdfsplit split file in pages"] TeXExec | ["--pdftrim trim pages from file(s)"] TeXExec | ["--process process file"] TeXExec | [""] TeXExec | ["boolean switches:"] TeXExec | [""] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [""] TeXExec | ["string switches:"] TeXExec | [""] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] TeXExec | [" "] So, the `s` part is being formatted correctly, the brackets are coming from somewhere else.
