Please add port select --summary option

[cdeil (Christoph Deil)]

I love how easy it is with port select to switch between versions.

But finding out which of the ports I have installed support port select is tricky. I have to google to find ​http://stackoverflow.com/questions/8016692/on-macports-what-ports-are-supported-by-port-select and then I see

$ ls /opt/local/etc/select
clang     cython    gcc       ipython   llvm      mysql     nosetests pep8      python    qt4       scala     sphinx
$ port select --show gcc
The currently selected version for 'gcc' is 'mp-gcc47'.
$ port select --show python
The currently selected version for 'python' is 'python27'.

Would it be possible to have one command (e.g. called --summary) that shows an overview table:

$ port select --summary
Portgroup   Selected   Options
gcc         mp-gcc47   none llvm-gcc42 mp-gcc45 mp-gcc47 mp-llvm-gcc42
python      python27   none python27 python32
...

To see the select ports that you've already installed, run:

port installed name:_select$

To see the available select ports that you haven't installed yet, run:

port echo name:_select$ and not installed

If you know some Tcl (or even if you don't, since it's not too complicated) I'd welcome a patch on this one.

To start, see source:trunk/base/src/macports1.0/macports.tcl@97839:3986-4094#L3986​ where this is implemented.

I have added the --summary option for port select. But, I could not test it properly. Please report any bugs.

Looks good at first sight – unfortunately I can't test right now because my working copy is busy tracking other changes and I don't want to risk mixing them (why don't we use git again? :/).

One thing I noticed is that your changes put set group [lindex $portlist 0] before the length check of $portlist. Since lindex doesn't fail on invalid indices that's not a problem per-se, I just think it would be a little cleaner to move it after the check. The indentation seems to be a little off in some places, too, but that's just a cosmetic issue.

Everything else seems to be in order – what's the problem with testing it? Don't have any select-capable ports installed? You can just install python_select or mysql_select – they won't have anything to select, but they should still show up just fine in your summary output.

Replying to ryandesign@…: You can combine those ideas to get the requested feature:

for i in `port -q echo installed and name:_select$`; do port select --list ${i%%_select*}; done

I've fixed a bug, and rearranged the code to make a cleaner diff. Please see attached.

Version 2 of the patch returned one portgroup only, moved the return statement to the correct location
