I’m using ruby 1.8.6 (2010-02-04 patchlevel 398) [i386-mingw32], WinXP  
and Notepad++ in the Unix mode (for line endings)

I have the following code:

q = [1.0, 4.0, 10.0, 27.0, 50.0, 600.0, 1000.0, 5833.0, 6250.0,  
1500000.0]  
x = q.each{|e| print Math.log10(e).to\_i, " "}  
p x  
r = q.collect{|e| Math.log10(e).to\_i}  
p r  
q.inject(Array.new(4,0)){ |h,e| if e \< 10000 then h[Math.log10(e).to\_i]  
+=1 }

i=0  
q.inject(Array.new(4,0)) do |h,e|  
if e \< 10000 then h[r[i]] += 1  
i += 1  
end

The first 5 lines work as expected. However, the first q.inject line  
and the q.inject block give the following errors:

D:\abc\>ruby doh2.rb  
doh2.rb:6: syntax error, unexpected ‘}’, expecting kEND  
doh2.rb:12: syntax error, unexpected $end, expecting kEND

My goal is to take the numbers in q and count how many are in the ranges  
1-9, 10-99, 100-999 and 1000-9999.

I thought maybe it was using the Math.log10 expression as an array  
index, hence the second q.inject code.

I have looked at an octal dump. No surprises there.

0000000 q = [ 1 . 0 , 4 . 0 , 1  
0000020 0 . 0 , 2 7 . 0 , 5 0 . 0 ,  
0000040 6 0 0 . 0 , 1 0 0 0 . 0 ,  
0000060 5 8 3 3 . 0 , 6 2 5 0 . 0 ,  
0000100 1 5 0 0 0 0 0 . 0 ] \n x = q  
0000120 . e a c h { | e | p r i n t  
0000140 M a t h . l o g 1 0 ( e ) . t o  
0000160 \_ i , " " } \n p x \n r =  
0000200 q . c o l l e c t { | e | M  
0000220 a t h . l o g 1 0 ( e ) . t o \_  
0000240 i } \n p r \n q . i n j e c t (  
0000260 A r r a y . n e w ( 4 , 0 ) ) {  
0000300 | h , e | i f e \< 1 0  
0000320 0 0 0 t h e n h [ M a t h .  
0000340 l o g 1 0 ( e ) . t o \_ i ] +  
0000360 = 1 } \n \n i = 0 \n q . i n j e  
0000400 c t ( A r r a y . n e w ( 4 , 0  
0000420 ) ) d o | h , e | \n \t i f  
0000440 e \< 1 0 0 0 0 t h e n h  
0000460 [r [ i] ] + = 1 \n \t i +  
0000500 = 1 \n e n d \n  
0000510

Any ideas as to what is going on here? I have also tried other inject  
statements that I know used to work, but they don’t now. Is inject  
broken in my version?

Thanks,  
Louise

“if” needs a matching “end”, unless you use the postfix form:

h[…] += 1 if e \< 10000

BTW, even if you’re using ruby 1.8.7, running ruby 1.9.x on your code  
with the -w flag can sometimes give better error messages.

There’s no ‘end’ on that ‘if’.

Thanks, that is just the ticket!

You need an “end” to go with the "if … then … " :

q.inject(Array.new(4,0)){ |h,e| if e \< 10000 then h[Math.log10(e).to\_i]  
+=1; end }
