Hi anyone/all,
Minor one, but it's been bugging me for a while. I want to see the
full descriptions of rake tasks sometimes, or at least, a lot more of
the description than 60 something chars. I had a look in rake.rb
around the various things, spotted the fact that there is code for
full descriptions, but that it's currently defaulted to false, I think
all the time.
Anyway, more useful than this, to me at least, is to be able to use a
known width of the screen where possible, so I added the following
code starting at line 2012 of rake.rb. I would have provided a patch
(and test cases), but I threw this together fast and dirty (inside the
gem install), so the procedure would have been significantly longer.
The following code is useful under environments where the user has:
* shopt -s checkwinsize (bash, or some other equivalent in other
shells (sets COLUMNS and ROWS)).
* export COLUMNS
It works as it previously did under conditions where the environment
variable is not available.
Thanks for Rake, it's awesome,
James.
Code:
=====
# if ENV['COLUMNS'] is nil, we want to supply 80 to
Integer(), else we get 0 for nil.
# if ENV['COLUMNS'] if for some reason 'foo', we need to
rescue and return 80.
display_cols = Integer(ENV['COLUMNS'] || 80) rescue 80
max_column = display_cols - name.size - width - 7
