Here is an issue: > https://pharo.fogbugz.com/f/cases/14254/AST-method-replaceWith-does-not-cha… I would say that they are correct. When I write source to source compilers, I admit that anything that I change in the AST (via replaceWith equivalent) has no valid source interval (since it does not exist in the original source). However, all unmodified nodes should keep their 'non-modified' source interval (since I may need it to fetch the relevant text from the source). If I want my modification to the AST to have valid source intervals, then, I need to regenerate the source from the modified AST. And only then they are valid. You may want to update the source interval when you do a replaceWith, but the only thing we will get with what you want to do is that, after a replaceWith, no source interval can be trusted since it may end up past the end of the original source string length.

Of course there are, but most will be a bit too complex I guess. But you are looking at this from the wrong angle. Kilon tried to explain this to you before. You have to see Pharo as a system, a world that contains a lot of things, all at your fingertips. You build applications by changing that system to become your system. There is not really such a thing as a complete standalone application in the classic sense. BTW, one could argue that even for classic languages like C, Java or C# this is not really the case since they use lots of libraries and OS services as well. One way to answer your question is that the system itself is the best example of (many) different applications. I know this won't help much, sorry. Maybe some of my recent articles can help: https://medium.com/@svenvc These are all meant as introductions/tutorials. Regards, Sven

Thanks for the report. This part will be cleaned as soon as we get some times and OSWindow fully plugged.

Pharo program "examples"

by Hans Schueren

Thanks Jan , i know that the system itself is the program. But there must be "Image" programs out there to download. I only want to download a program ( Folder with image and exe [Pharo Container] ) Online. Just to see and start the program and see how it opens. ( like a normal program [ Pharo IDE is shadowed] ). Guess that i am a user. I have heared about Pharo and want to test a real program. Hans Hello again , are there any Pharo Program examples online ? I dont mean normal examples from coding. What i mean are end-user programs. Completely ready Online for downloading. Regards Hans

Well, not really. Technically, tokens are used to drive a parser from a scanner. If an AST node knows how to relate itself to its original source code chunk and is able to print itself correctly, then tokens are redundant. In short, if you work with parsers, you'd better know what tokens are. If you're only working with the AST, tokens are redundant and noise (i.e. they often have a type (or more than one) which is only understood by the parser). Example of how it is done: RBPragmaNode accessing-tokens gives access to left and right, which are positions, not tokens.
