If my var1 is equal to...
<cfset var1 = "1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50,
51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100,
101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130">
I get this for the output:
1
It should be 1-130
Still not quite right:
initial : 1,2,3,4,5,6,10,11,12,13,14,20,25,30,31,32,33,50
desired : 1-6,10-14,20,25,30-33,50
computed: 1-6,10-14,20-20,25-25,50
^^ ^^ ^^
The code in my initial post works correctly, and is reposted (with slight
optimizations) below:
<cfset var1 = "1,2,3,4,5,6,10,11,12,13,14,20,25,30,31,32,33,50" />
<cfset last = "" />
<cfset var2 = "" />
<cfset startedRange = false />
<cfloop list="#var1#" index="curr">
<cfif last EQ curr - 1>
<cfset startedRange = true />
<cfelseif startedRange>
<cfset var2 = var2 & "-" & last />
<cfset startedRange = false />
</cfif>
<cfif NOT startedRange>
<cfset var2 = listAppend(var2, curr) />
</cfif>
<cfset last = curr />
</cfloop>
