Hi,

First of all I would say that I really appreciate Subtle. I was an Awesome WM user but I don't really like lua. Subtle is a good alternative and ruby is a more funny . Nice job.

Thanks :)

But when I have windows on more than one view, I can only use numbers to select the windows I want. Is it normal?

Hum, I cannot reproduce that. The selector works fine here, can you post me the output of subtler -vl -p 'puts "#{param}: #{param.clients.map(&:instance)}"' and tell me what combination doesn't work?

You can see the sublet files here: https://github.com/cedlemo/cedlemo-sublets/blob/master/cpubar/
Where is the problem?

That is an internal problem, subtle currently uses <> to separate format strings and apparently that clashes in strsep which is a bit odd. I changed the separator in r3177 to ^ and you can use the > without problems, just update later.

So my questions are: does sur maintains a local database/cache of installed sublets (like rpm or dpkg and where it is)?, is there a way to clean this catabase/cache?

subtle and all components honor the XDG specs, therefore cache files are stored in _/.cache/sur. Just delete both files and re-run sur and list e.g. locallly installed sublets. You can manually delete sublets as well, just cd into /.local/share/subtle/sublets and remove the broken file.

For the pb with selector I have done different tests:

1⇋ terms: ["urxvt"]
2⇋ www: ["luakit"]
3⇋ mails: ["Mail"]
4⇋ gimp: []
5⇋ dev: []
6⇋ multimedia: []
7⇋ virt.Mach: []
8⇋ divers.: []

With this configuration I don't have pbs

With this configuration I can't use arrows (left/top/right/bottom) to select a window
but I can use the corresponding number on the keypad to select a window
I have only three choices urxvt mail (thunderbird) and luakit.

keepassx and mail (thunderbird)

For the problem with sur:

I have cleaned the directory ~/.cache/sur/ and run sur list but now sur doesn't list any sublets and I still have the message:

/usr/lib/ruby/site_ruby/1.9.1/subtle/sur/specification.rb:113:in `eval': (eval):31: syntax error, unexpected tLBRACE, expecting ']' (SyntaxError)

from /usr/lib/ruby/site_ruby/1.9.1/subtle/sur/runner.rb:158:in `run'
from /usr/bin/sur:20:in `<main>'

I will try to restart subtle.

I have find a solution for the problem with sur.

I had a sublet specifications which was not well formated, so the line (113) spec = eval(File.open(file).read) in the file specification.rb crash.

I have modified the file specification.rb:

@ begin # Create spec
spec = eval(File.open(file).read)
spec.path = File.dirname(file)
rescue SyntaxError => se
puts file
spec = nil
end@

Now when I use "sur list" for example, if there is a bad specification file, an error is displayed and all of the good files are listed.

For my pb with selector.rb:

when I call selector.rb from the terminal :

ruby selector.rb

But when I call it via subtle and a key combinaison It doesn't work as expected.

Here's the configuration in my subtle.rb:

begin
  require "#{ENV["HOME"]}/.config/subtle/subtle-contrib/ruby/selector.rb" 
  # Set fonts
  Subtle::Contrib::Selector.font = "xft:Droid Sans Mono:pixelsize=66:antialias=true" 
  rescue LoadError => error
    puts error
  end

  grab "A-Tab" do
    Subtle::Contrib::Selector.run
end

And here is the error message:

ArgumentError: comparison of Fixnum with nil failed

I don't see the benefits of this, doesn't the if block below cover that case already?

For my pb with selector.rb:

when I call selector.rb from the terminal :
[...]
It works

But when I call it via subtle and a key combinaison It doesn't work as expected.

I fixed that error in r113 of subtle-contrib.

hum .. maybe I don't really understand what you want to say :) ) ( my english is not very good)

my answer :

I don't see any if block below in the file specification.rb and if there is code that cover that case, why any syntax error in a specifications file make

sur list

The error cannot happen there, what is your version of subtle?

Here is the code of #load_spec: http://subforge.org/projects/subtle/repository/entry/data/sur/specification.rb#L107

When #eval raises an exception it is caught by the surrounding try/rescue.

I use the subtle-hg package from archlinux
subtle 0.10.3179

I look at http://subforge.org/projects/subtle/repository/entry/data/sur/specification.rb#L107 and it's not the file I have

So what is different besides some missing brackets, that I removed a few minutes ago? I have exactly this file here on my machine.

-_-',

so ok I am sorry it's the same file. And No the if loop only check if spec is empty and rescue don't handle eval error

This:

begin # Create spec
spec = eval(File.open(file).read)
spec.path = File.dirname(file)
rescue SyntaxError => se
puts file
spec = nil
end

handle syntax error for eval:

see here :
http://stackoverflow.com/questions/542845/how-to-rescue-an-eval-in-ruby

It turns out that, by default, the "rescue" statement does not catch all exceptions, but only those that are subclasses of StandardError. SyntaxError is a sibling/cousin of StandardError, not a subclass of it, so the rescue statement doesn't capture it unless explicitly told to.

Oh you're right, didn't think about SyntaxError. Fixed in r3181.

Ok so all my pbs have been resolved

Thanks you.
