  So what's the point of include and not_include if you have to do this 
  weird size thing? 

 include/not_include check the return value of the match arg command 
 and whether it includes or doesn't include the argument. 

 A match API call in Augeas' API returns a list of paths that match the 
 argument you pass, so you're actually checking whether those paths 
 include or don't include a certain value.  It doesn't return the values 
 of those nodes, which is what you expected. 


Well I expected match /files/home/user/.ssh/config/IdentityFile 
not_include ~/.ssh/user2nd_rsa to be true if ~/.ssh/user2nd_rsa wasn't 
one of the values found with the match (and false if it was).  That 
obviously isn't how it works in practice.  

In augtool match /files/home/user/.ssh/config/IdentityFile returns:

/files/home/user/.ssh/config/IdentityFile[1] = ~/.ssh/id_rsa
/files/home/user/.ssh/config/IdentityFile[2] = ~/.ssh/user2nd_rsa
/files/home/user/.ssh/config/IdentityFile[3] = ~/.ssh/git_user_rsa

so I'm still not understanding why the not_include in the onlyif returns 
false in my case -- Unless it is trying to check against the entire line 
where I'll never be certain if it is [2] or [3] or something else so it 
will be fairly useless for me in this case.  

On the bright side the size thing works (just that I would have never 
thought of trying it.).

 

 It's possible the get arg command would work better with 
 include/not_include, except that API call will only match a single path 
 and return one value value - so isn't much help with include. 

 We could do with something better here in the provider for sure, care to 
 raise a feature request?  Please add me to the watchlist if you do. 


I suspect the only features I need are more examples in the documentation.

[Puppet Users] augeas onlyif problem

2013-11-06 Thread Jist Anidiot 
I'm trying to make sure a specific user has a special ssh key used as his 
identity file.

so I'm trying something like:

 augeas{user_second_key:
context = /files/home/user/.ssh/config,
changes = [ ins IdentityFile after 
/files/home/user/.ssh/config/IdentityFile[last()],
  set /files/home/user/.ssh/config/IdentityFile[last()] 
~/.ssh/user2nd_rsa,
 ],
onlyif = match /files/home/user/.ssh/config/IdentityFile not_include 
~/.ssh/user2nd_rsa, 

  }

However it adds the line every puppet run.  I'm wondering what I might be 
doing wrong.
