213 :: Hello, and a few questions!

  Team,

  I came across Nimrod 4-5 days ago. The language looks quite appealing!

  As an exercise, I wrote a small script for checking the 'alive' status of a specified set of HTTP sites. You can find it at https://github.com/js-ojus/heartbeat.nimrod. Please provide some feedback on how to make it more Nimrod-like. That I could learn the language enough (in three days) to write the said program in about 4 hours is, in my opinion, a testimony to both the language design choices and the standard library breadth. Congratulations to Araq and the other authors!

  Based on my experiences in writing the above, I have some questions.

  1. In the proc doesServerExist, I had originally written the following snippet to find out if dig received an answer:

  if ln =~ re", ANSWER: (\d+),":
    let n = parseInt(matches[0])
    if n > 0:
      ...
  Run

  This, however, did not work -- there was never a match. I then tried almost all the procs in the module re to no avail. I would appreciate some suggestions.

  2. In the module smtp, is there a way I could set a custom 'From:' address that includes a name?
  3. In the module httpclient, is there a way to have separate timeout specifications for 'connect' and 'read'?

     Thanks!

  The flags of the re constructor default to {reExtended, reStudy}. reExtended means whitespace is ignored in your pattern so you can keep them readable. Use this instead:

  
  if ln =~ re(", ANSWER: (\d+),", {}):
  Run

  or rewrite your pattern so that it uses \s instead.

  Hello!

  (2) In the module ``smtp``, is there a way I could set a custom 'From:' address that includes a name?

  Yes, you can specify extra headers when creating your message:

  
  var msg = createMessage(subject, body, mTo, @[], [("From", "from@address")])
  Run

  This may work, I haven't tested it btw.

  (3) In the module ``httpclient``, is there a way to have separate timeout specifications for 'connect' and 'read'?

  Sorry, no way to do that.

  I noticed that you use .format in your code. You can use the % operator to make it a little bit nicer if you wish:

  
  writeln(log, "$1 : [ERROR] $2 : $3." % [tAt, server, "could not be resolved/reached"])
  Run

  Araq: The flags of the re constructor default to {reExtended, reStudy}. reExtended means whitespace is ignored in your pattern so you can keep them readable.

  Thanks, I used the module pegs successfully (it has increased the size of the binary significantly, though).

  dom96: Yes, you can specify extra headers when creating your message ...

  Thanks, it has worked!

  Sure, I have adopted it!
