Within a class, methods are organised into "protocols" that are shown in the third browser pane from the left of Figure *testCellStateShouldBeOffEmpty*. We will group our "tests" inside a protocol of the same name. to produce this nice looking PDF showing the note indented with dividing lines... Now that was real easy to do!!

I can't imagine making a similar change as easy in a Markdown processor in some other language. --------------- Next, in common.tex [1] I found... { \newcommand{\dothisicon}{\raisebox{-.5ex}{\includegraphics[height=1.2em]{pharo}}} \newcommand{\dothis}[1]{% \medskip \noindent\dothisicon \ifx#1\empty\else\quad\emph{#1}\fi \par\smallskip\nopagebreak} } and discovered I could do this in the Pillar markup...

However changing this to be less of a hack like this... 'dothis' = anAnnotatedParagraph annotation asLowercase ifTrue: [ ^ canvas command name: 'dothis' ; parameter: [ super visitAnnotatedParagraph: anAnnotatedParagraph ] ]. doesn't quite work, since the first Pharo icon runs onto the previous line... That can be fixed as follows.... PRLaTeXCommand>>name: aString stream newLine. "<---THIS LINE ADDED" stream << $\ << aString but I don't know if that is the right thing to do. Maybe there are times when you want commands to run on from a line. What would be the right thing? Also, is it reasonable to add this new annotation type? i.e. might it be integrated soon ? :) :) .

storeOn:/readFrom: symmetrical?

by Rick Kitts

Hi. A basic question I hope someone can answer. This works: â cut here --- | stream aInt | stream := (String new:20) writeStream. aInt := 23. (aInt storeOn:stream) = (aInt class readFrom:(stream contents)) â cut here --- This doesnât (generates an error): â cut here --- | stream aTime | stream := (String new:20) writeStream. aTime := Time now. (aTime storeOn:stream) = (aTime class readFrom:(stream contents)) â cut here --- To the question then. Assuming the second case isnât wrong in some fashion I donât understand, is it the case that storeOn:/readFrom: is supposed to be symmetrical for all classes? I ask it that way because there are a couple of Kernel classes where Iâve seen this to not be the case. TIA, âRick
