[UFFI] Call a function where argument type is char ** (argv)

by Blondeau Vincent

Hello, I have written a R bridge in Pharo and I would like to migrate it from NativeBoost to UFFI. Most of the changes are easy to do but I am stuck to a double pointer problem. I have to call the function: int Rf_initEmbeddedR(int argc, char ** argv). I know how to give the int but the char ** is a problem. With NB, I managed to have this (working) code: "This is 32bit... too bad..." strings := OrderedCollection new. par := NativeBoost allocate: 4 * params size. params keysAndValuesDo: [ :i :each | | str | str := each asNBExternalString. strings add: str. par nbUInt32AtOffset: (i - 1) * 4 put: str value ]. self prim_initEmbeddedRargc: params size argv: par ] ensure: [ "Free the memory we allocated" par ifNotNil: [ par free ]. strings ifNotNil: [ strings do: [ :each | each free ] ] ] With a primitive call: Self nbCall: #(int Rf_initEmbeddedR(int argc, char *argv)) Do I still need to create my own array of strings or FFI creates it for me? How? Thanks in advance for your answers, Vincent !!!************************************************************************************* "Ce message et les pi?ces jointes sont confidentiels et r?serv?s ? l'usage exclusif de ses destinataires.

Do we want AST-Debugger?

by Denis Kudriashov

Hi. Look at AST-Interpreter project which includes AST-Debugger http://smalltalkhub.com/#!/~Pharo/AST-Interpreter. Code is so simple comparing to "bytecode simulation" approach of current debugger. AST debugger are independent from bytecode set. It just visit AST-nodes to simulate code execution. But current debugger simulates bytecode. It depends on current bytecode set. There are few kinds of BytecodeEncoders. To understand how current debugger is working you need to know many VM details. So my question is why our debuggers are not based on AST interpreter? Why it is bad idea? (if it is bad). Best regards, Denis

There are quite some progress on the plugin work. Eliot made x64 FFI working a couple months ago. Nicolas Cellier have already been looking for Number plugins for a while. Many Slang compilation bugs related to 32-64 bits dependency were fixed, so many plugins work out of the box.
