This also may not be the most elegant solution, but it works:
<cfset write_toggle = 1>
<cfloop from="#myString_len#" to="1" step="-1" index="i">
<cfif write_toggle eq 1>
<cfset myProteinSequence = Insert(" ",myProteinSequence,i)>
</cfif>
<cfif mid(myProteinSequence,i,1) eq ")">
<cfset write_toggle = 0>
<cfelseif mid(myProteinSequence,i,1) eq "(">
<cfset write_toggle = 1>
</cfif>
</cfloop>

Subject: Conditional text Insert into a String
I have a string that looks like:
... KPPET(L ATT)(I GAT)TTID ...
And I want to end up with a string that looks like:
... K P P E T (L ATT) (I GAT) T T I D ...
Notice that there is a space in between each letter EXCEPT in the (X YYY)
pattern where YYY has to stay together with NO intervening spaces. ( X YYY )
would be OK too.
Right now, I am adding spaces in a loop:
<cfset myString = "#ProteinSequence#">
<cfset myString_len = Len(myProteinSequence)>
<cfloop from="#myString_len#" to="1" step="-1" index="i">
<cfset myProteinSequence = Insert(" ",myProteinSequence,i)>
</cfloop>
But this adds spaces everywhere, even where I don't want them , in the "YYY"
pattern, so I get:
... K P P E T ( L A T T ) ( I G A T ) T T I D ...
If I could do a "conditional insert" where it stops inserting a space when
it hits the first ")" and start again after it hits the next "(" but I am
not sure how to do it?
Any ideas would be appreciated, otherwise I need to explore regular express
replace with backreferences (maybe), which is a prospect too horrible to
contemplate ...
