[augeas-devel] Help splitting a key on a slash character

[Marc Riddle]

That was a huge help, I'm very close now, but can't quite seem to get it
right. Here's what I have right now:

--- snip ---
module Sssd =
  autoload xfm

  let eol = Util.del_str "\n"

  let key_re = /[^#;:= \t\n[\/]+/

  let dels (s:string) = del s s

  let eq = del /[ \t]*=[ \t]*/ "="

  let secname = /[^]\/]+/

  let value = /[^ \t\n][^\n]*/

  let comment = [ del /([;#].*)?[ \t]*\n/ "\n" ]

  let kv = [ key key_re . eq . store value . eol ]

  let domainsechead = dels "[" .key secname . dels "/" . [key secname] .
dels "]" . del /[ \t]*[;#]?.*/ "" . eol

  let nodomainsechead = dels "[" . key secname . dels "]" . del /[
\t]*[;#]?.*/ "" . eol

  let sechead = domainsechead | nodomainsechead

  let entry = comment | kv

  let section = [ sechead . entry* ]

  let lns = (comment) * . (section) *

  let filter = (incl "/etc/sssd/sssd.conf")
      . Util.stdexcl

  let xfm = transform lns filter

   let conf = "
[main]
foo = foobar
[domain/LDAP]
bar = barfoo
"

   test Sssd.lns get conf =
      {}
      { "main"
        { "foo" = "foobar" } }
      { "domain"
        { "LDAP"
         { "bar" = "barfoo" } } }
        { "LDAP"
         { "bar" = "barfoo" } } }


--- snip ---

Which results in the following tree:

{ 
  {  }
  { "main"
    { "foo" = "foobar" }
  }
  { "domain"
    { "LDAP" }
    { "bar" = "barfoo" }
  }
}

How do I get 'bar' to be inside of 'LDAP'? Sorry if these are basic
questions, I'm just getting up to speed with augeas, but am hoping to get
several more lenses written as I get more comfortable here...


Thanks,

Marc
