Hi Martin!
I have question about your manual (Ini agent description ).
I have one config file which is read by the scr agent, but in the
config file i have following entry in the config file:

# variable1 = value
# variable2 = value
# variable3 = value
# variable4 = value

Is it possible to configure the scr agent so that he can read and write
those values without # sign?

This will give you regular variables with value_type 0 and commented-out ones
with value_type 1.

`ag_ini (
`IniAgent ( "/foo/bar.conf",
$[
"options" : [ "global_values" ],
"params" : [
// unfortunately this is the simplest way to write
// '"whatever = whatever", including whitespace'
$[ "match" : [ "^[ \t]*([^=]*[^ \t=])[ \t]*=[ \t]*(.*[^ \t]|)[
\t]*$",
"%s %s"
]],
// same as above, with "# " added
$[ "match" : [ "^# [ \t]*([^=]*[^ \t=])[ \t]*=[ \t]*(.*[^
\t]|)[ \t]*$",
"%s %s"
]],
],
// something which does NOT match the above, because comments are processed
first
"comments" : [ "^#[^ ].*" ],
"subindent" : " ",
]
)
)

Unfortunately, if you add just "#" instead of "# " then you have much harder
time
negating that regex to specify what constitutes an uninteresting comment.
IIRC for smb.conf, we used '#' for free comments and ';' for
disabled values to solve this problem


Let's say we have
foo = bar
# baz = quux

SCR::Read(.myagent.value.foo) -> "bar"
SCR::Read(.myagent.value.baz) -> "quux"
SCR::Read(.myagent.value_type.foo) -> 0
SCR::Read(.myagent.value_type.baz) -> 1
SCR::Write(.myagent.value_type.foo, 1) // comment it out
