Re: [Pharo-users] Adding a new reserved word

I am not very familiar with the compiler machinery but look for references to StdVariables in: VariableNode class>>initialize Encoder>>cantStoreInto: this is quite a deep part of the system, but in principle it can be changed if you know how.

Adding a new reserved word

by Carla F. Griggio

Hi everyone! I want to add a new reserved word to a Pharo image. I tried to find the code that gives special treatment to words like nil, true, false, self, etc. and add my new reserved word, but as though I tried to immitate some things, I was not successful. Â¿What could be the right way to do this? Â¿Can I add a reserved word just adding some code on a Pharo image? Thanks! Carla. PS: The object of doing this is nothing serious, I just want to make a friend laugh with a silly joke :)

Re: [Pharo-users] A question about application deployment.

by Adrian Lienhard

Yes, there certainly is a lot of stuff that can be removed (I'm currently working on removing the requires algorithm and making it reloadable from an external package). I'd love to see the other cleanup scripts. Esteban, could you share what you did to get a <5MB image?

Re: [Pharo-users] A question about application deployment.

by Mariano Martinez Peck

Be aware there are much more cleanUps or shrinks that can be done regarding the needs of your application. I am playing a bit with them now. Esteban did a lot of shrinks for a PharoCore image so that to run on IPhone (less than 5 MBs).

See the methods #cleanUpForRelease and #cleanUpForProduction. The last one e.g., removes all unit tests.

A question about application deployment.

by Rayne

http://code.google.com/p/pharo/wiki/HowToDeployAnApplication Oh that page, it talks about "shrinking" an image: "Reduce the image size by throwing out anything that is not required by your app and which is useless for your customer (unit tests, dev tools)." but it doesn't explain /how/ to do so. How does one "throw out" stuff like unit tests and dev tools? -- View this message in context: http://n4.nabble.com/A-question-about-application-deployment-tp1591431p1591… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

This way, you can write much cleaner code as you can call your methods on the literal floats that the compiler generates: 4.5 addCent: ... In addition, you should have a look at double dispatch and especially Dan's parametarized double dispatch used for the operators. This allows you to actually use the math symbols... with your own classes if it makes sense: e.g. 4.5 + 5 cents Plus is implemented like this: + aNumber "Primitive. Answer the sum of the receiver and aNumber. Essential. Fail if the argument is not a Float. See Object documentation whatIsAPrimitive." <primitive: 41> ^ aNumber adaptToFloat: self andSend: #+ when the primitve fails (aNumber is not a float), than is sends a message to your object so that you can implement the calculation in the class (whatever that is), by implementing this method: adaptToFloat: aFloat andSend: aSelector No idea if that makes sense in your case... there have been Music software developed in Squeak years ago that extenden numbers quite extensively to provide what one would these days call a "Music Domain Specific Language" ;-) Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe.

Subclassing Float?

by Ch Lamprecht

Hello, I tried to build a subclass of Float without success. More precisely, I did not find out how to build instances from it. Is subclassing Float something I should not do? I am trying to build objects, that represent Audio frequencies. They should behave like Floats but have some additional methods like 'addCent: anOffset' or 'deltaCent: aFrequency' (cent refers to a logarithmic scale used to express frequency relations). Cheers, Chris
