Fwd: Misc primitives & read-only objects

 

 

Hi all,

I'm trying to set literals as read-only in Pharo. I've got this problem with this Misc primitive:

translate: aString from: start  to: stop  table: table

"translate the characters in the string by the given table, in place"

<primitive: 'primitiveTranslateStringWithTable' module: 'MiscPrimitivePlugin'>

<var: #table  declareC: 'unsigned char *table'>

<var: #aString  declareC: 'unsigned char *aString'>

start to: stop do: [ :i |

aString at: i put: (table at: (aString basicAt: i) + 1) ]

The primitive mutates aString without checking if it's read-only.

What is the right way in Smart syntax plugin to add the read-only check ?

I think the right way is to rewrite the primitive as a SmartSyntaxPlugin.  I will do this today.  These translated primitives are a cute idea but fundamentally problematic.
