Howdoi – Instant Coding Answers via the Command Line

Some queries I tried (results were not perfect but pretty decent):

    howdoi split string javascript
        var split = 'john smith~123 Street~Apt 4~New York~NY~12345'.split('~');

        var name = split[0];
        var street = split[1];

        etc...

    howdoi get day from date javascript
        var date = new Date();
        var day = date.getDay();

    howdoi iterate coffeescript
        ages = []
        ages["jim"] = 12
        ages["john"] = 7

        for k,v of ages
          console.log k + " is " + v
  
    howdoi get referrer url php
        <?php

        session_start();

        if (!isset($_SESSION["origURL"]))
          $_SESSION["origURL"] = $_SERVER["HTTP_REFERER"];

        ?>

Why do you need the Apple Developer Program Enrollment ID? I also tried to apply to the iOS Developer Program this weekend. I applied, I paid and I got my activation codes. But then when I tried to activate with my Apple ID I got an error saying (in my case) they "were not able to successfully verify my identity". In that error message there was an Enrollment ID# consisting of both letters and numbers, a total of 10 characters, that I was supposed to include when contacting the support regarding this issue. I have not seen the same Enrollment ID somewhere else in the process and therefore I assume it is some kind of internal ID for my signing up process and you should only see it/use it when you hit some problems during the process.

I'll figure it out one of these days.

One that fails rather badly:

format dates django templates Returns simply "date", despite StackOverflow having lots of hits: http://stackoverflow.com/search?q=format+dates+django+templa...

But some others are super cool:

create datetime from epoch >>> datetime.datetime.fromtimestamp(1284286794)

One suggestion is that by default I would include the link to the stackoverflow page.

Some color might be nice to make it extra sexy, look at the colorama package to do it easily cross platform.

    $ howdoi kill someone
    ps aux

    $ howdoi clean up blood stains
    No, you cannot achieve that with PHP [...]

He hasn't got the hint with lmgtfy links so I'll try a different tack...

USER_AGENT = "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1309.0 Safari/537.17"

to something a little more honest though, unless you have a good reason for keeping it.

I thought at first you had compiled a corpus of knowledge, but this is much better, but with the requirement of internet access.

Google for _split string javascript_ or the other queries, and you'll get basically the same results, just not limited to StackOverflow as howdoi does.

Maybe if I were more married to my command line this would be useful, but in general, I'm only there for bash and git. I spend most of my time in an editor, so popping over to the browser is no more work for me than showing the terminal.

I'm thinking seeing the question, and listing all questions so I know which -pX I want ;)

"Have I ever had this problem ?" "Did I save the answer ? (In evernote or whatever)"

To think about those two answers I need around 2000ms. After 1000ms I wrote the query and asked google again... Is it only me? I wish I would use my local knowledge database but I only use it when I`m not lucky with google after the first queries.

I was very impressed by responses to queries like this:

    howdoi retrieve the keys from an array of hashes in ruby

        hash = {"apple" => "fruit", "carrot" => "vegetable"}
        array = hash.keys   #=> ["apple", "carrot"]

However, something bugs me a little; Is there any reason for not mentioning Stack Overflow in the README?

Tried "howdoi split string zsh" and it gave me a good answer.

Bummer. It looks really cool.

>>> howdoi foo bar

Or as a magic function for ipython.

howdoi -a parse HTML with regex

$ howdoi mvp pattern

$ howdoi wittgenstein

$ howdoi hopfield network

$ howdoi feed forward network

$ howdoi artificial heart
