ya, this is what do-notation is for - the parsers are monads. i'm not entirely sure what you mean by 'result' of the three parsers, but this returns a tuple of all three results together which you then pattern match on yourself. if you're not sure how tuples work it is 100% necessary for learning haskell so go read that chapter of learn you a haskell/your lecture notes.
code:
p1 :: Parser Int
p2 :: Parser String
p3 :: Parser Double

p4 :: Parser (Int, String, Double)
p4 = do
    int  <- p1
    str  <- p2
    dubs <- p3
    return (int, str, dubs)
liftM3 (,,) p1 p2 p3

Thank you again, that makes sense. I (think) I am fine with tuples, and yes learn you a haskell is what the lecture notes are based on haha

This is too difficult. ive looked around and cant find any similar examples at all. the two best pages on parsec in haskell ive found (http://book.realworldhaskell.org/read/using-parsec.html and http://unbui.lt/#!/post/haskell-parsec-basics) dont seem to cover it all. i have something like..

code:

example_string = "  integer(kind=4), parameter:: ipppp = 150" --trying to parse the beginning, before the ccomma. the (kind=4) part is optional

kind_parser :: Parser Integer
kind_parser =
    do
        string "(kind="
        num <- integer
        char ')'
        return num

type_parser :: Parser VarType
type_parser =
    do
        whiteSpace
        w <- word
        --this is where i struggle, ive tried using num <- optional kind_parser - but that doesnt work, the idea is to capture the value of kind if it is available, if not then set it to 4
        comma

ive clearly got a fundamental problem, causing these lots of small issues. but it seems like id only know these answers if id came accross it before, which i havent as part of the course

just a job search for your first job is a bad place to "phone it in." even a depressed person must make choices where to apply greater or lesser effort, and your first job search is a place where more is better.

another way to put it: rejections during your first job search may often have very little to do with you as a candidate

if you don't already have connections to the industry to lean on, it's a numbers game. just gotta make a very large number of attempts, no way around it

no use beating yourself up for failures, either. repeated failure is an expected part of the process. can't let it get to you, because it's not your fault. just keep grinding out cover letters and sitting for interviews.

lots of things in life will not immediately punish you for withdrawal or dysfunction. not all important things are "challenging"

you can phone it in at work and not get fired

you can ignore your mothers email and still get invited to Christmas

you can fail to call friends for long periods and still be welcome when you recover

Mr. b.s.d. is right. It's hard to not be made to feel like poo poo when you get turned down repeatedly. It can be really tough, but always try to keep in mind that software development is one of the most subjective fields for interviews. There are always people who are very smart and have lots of credentials that get turned down, so you are not alone.

this would be a much easier pill to swallow of grueling 4 hour technical interviews werent the norm. it's really hard to convince yourself that 'it's not personal' after the rejecters spend many hours and dollar interviewing you.

Valeyard posted:

'optional' discards the result (presumably it's meant to be used for comments and stuff), you want to use 'option' instead which you supply with a default value to return if the parser fails.

This is all in the parsec docs* which I got to by googling "parsec optional". Nobody expects you to understand those overly general type signatures immediately (there's a reason that scala's docs lie about the type sigs) but the description for these combinators make the difference clear.

*: https://hackage.haskell.org/package/parsec-3.0.0/docs/Text-Parsec-Combinator.html

e: for now, just pretend that 'ParsecT s u m a' is actually 'Parser a' and ignore the 'Stream' bit to the left of the =>. that way the horrific 'optional :: Stream s m t => ParsecT s u m a -> ParsecT s u m ()' becomes 'optional :: Parser a -> Parser ()' and it's clear that is discards the result and returns () instead.

option effectively has the type 'option :: a -> Parser a -> Parser a'. as for how you'd know to do this, well the most significant type parameter, the type of the actual value(s) inside, is always the last one in a monad anyway

so it'd be something like

code:

type_parser = do
    whiteSpace
    w <- word
    num <- option 4 kind_parser
    comma
    -- continue parsing the rest of the string
    return (VarType{type=w, kind=num, inout=fart, name=butt, value=piss})

(depending on how a value of type VarType is constructed of course)

a nontrivial part of haskell (as I'd imagine any language unless you want to reimplement everything yourself) is looking through relevant libraries for a function that does what you want. try the search engine https://www.fpcomplete.com/hoogle or hayoo (remember to limit your search to the package parsec and even the version if you're using an old one)

cobol, visual basic, fortran, and php are the most dread-inducing, d is the least

visual basic, cobol, php, and actionscript are the most embarassing languages, clojure, go, and ocaml are the least

i would do vbs again if the money were right. i'm not sure i can say that about php.

edit: actually no. i'm never doing either one. i might rather eat 3 meals a day in soup kitchens and sleep on a subway grate than work with either technology on a daily basis. it would at least require serious thought whether homelessness was preferable to going back to that world
