Various coding styles I hate seeing. It's a rant, but a fun one. Uses Spiderman to help illustrate my angst.

4. REALLY STUPID STUFF
$ , $ ,$ , $ , $ , $ , $ , $
a b i j k l m n
$,$,$,$, $,$,$
f u c k y o u
Trailing spaces STOP IT!
$a,@ra,%ah

5. TABS VS. SPACES
The eternal struggle
Do not mix tabs and spaces
Do NOT mix tabs and spaces
DO NOT mix tabs and spaces
DO NOT MIX TABS AND SPACES!
Best rule? No tabs, only spaces
6. MISUNDERSTANDINGS
m pwithout checking value
a
#mpEP,IT
a XRLS
m %gs =mp+ $ = $is$}'g' ) ky %is
y ae
a ( _ > kd{_{ae} , es kd;
#mpBOKLS
a LC IT
m @otd=mp {$-[]
y sre
a
_>0
}
sr {$-[]<>$-[] }
ot

7. SWITCHES
i
f
(oe
$n) {.}
..
esf(to
li $w) {.}
..
esf(tre {.}
li $he) ..
es
le
{.}
..
m %ipth=(
y dsac
$n
oe = sb{.}
> u ..,
$w
to = sb{.}
> u ..,
$he = sb{.}
tre > u ..,
)
;
i (eit $ipth$nu}){
f
xss dsac{ipt
$ipth$nu}>..;
dsac{ipt-(.)
}es {.}
le ..
8. EMPTY IF CLAUSE
i (smtig {
f $oehn)
#d ntig
o ohn
}es {
le
#teata wr
h cul ok
}
9. RETURN VARIABLES
m $eun
y rtr;
i (ti){
f $hs
..
.
$eun='hs;
rtr
ti'
}esf(aohrtig {
li $nte_hn)
..
.
$eun='ht;
rtr
ta'
}
rtr $eun
eun rtr;
12. GOTO HELL;
NOT FOR WORKFLOW!

13. WHY?
Because code is alive and grows
Sometimes to ridiculous age
You might not be the last
And the next might know your address
