Re: [Pharo-dev] Code generation for ASTs with syntax errors

Ok. Now I need to evaluate if the time spent writing a GT presentation is worth the performance impact of using the GT Inspector use compared to writing a dedicated version of a faster tree viewer ;) Thierry 2015-05-19 10:18 GMT+02:00 Tudor Girba <tudor(a)tudorgirba.com>: > It's already available :). > > > [image: Inline image 1] > > Doru > > > On Tue, May 19, 2015 at 10:18 AM, Jan Vrany <jan.vrany(a)fit.cvut.cz> wrote: > >> >> > >> > with the GT inspector, it has a very nice AST view: >> > >> > >> > The AST view of the GT Inspector is useless for serious work. >> > >> > >> > I've been spending the past weeks and months looking at ASTs, SSA and >> > CFGs of code and I allways need a twin view: node + source code (and >> > selecting one of those node select the relevant portion of the code). >> >> Agree, something like this would be even nicer... >> >> Jan >> >> >> >> > > > -- > www.tudorgirba.com > > "Every thing has its own flow" >

I've been spending the past weeks and months looking at ASTs, SSA and CFGs of code and I allways need a twin view: node + source code (and selecting one of those node select the relevant portion of the code).

Anyone knows why we can set only bold and/or italic emphasis on a LogicalFont? StringMorph new contents:'hello';emphasis:1;openInHand. -> bold text StringMorph new contents:'hello';emphasis:8;openInHand. -> no change, it should be underlined This is different if the default font is a StrikeFont StringMorph new contents:'hello';emphasis:1;openInHand. -> bold text. StringMorph new contents:'hello';emphasis:8;openInHand. -> underlined. I found the place in LogicalFont, where other emphasis' are filtered out, but I don't understand why. nicolai > Nicolai > Am 15.05.2015 5:21 nachm. schrieb "Sean P.

It seems to me the advantage of this change is that it allows compilation to complete rather than bombing out part way through. But just because compilation finishes, doesn't mean it needs to be committed into the runtime system. > Syntax errors shouldn't require immediate fixing during compilation per se, but there should be a way to deal with them "at compile time" âwhatever that means for us. > For instance, faulty methods could have a flashy icon in the browser; I think I'd even color the whole package-class-protocol-selector in red if either of them contain faulty methods. > > I guess it *should* mean that the faulty-compiled-method is not committed but stored in a temporary buffer similar to how editing source is effectively done in a temporary buffer.

But the result is that it is very easy to loose code. And you never know what is âreally savedâ and what not. But in general: I know that this is one of those things that I will not be able to convince anyone that it is useful before it is doneâ¦ which is good: I like to explore directions that everyone else rejects immediately.
