It turns out the FunctionGraphMorph in package Morphic-Widgets-Extras also lets one make plots.

You can display a plot in Erudite by simply inserting something like this in a document:

[[[ | g d |
d := -1.
g := FunctionGraphMorph new.
g domain: (-4 to: 4).
g addFunction: [ :x | x \\ d ] color: Color green.
g addFunction: [ :x | x // d ] color: Color red.
g ]]] embedIt

Proposal: remove gnuplot support, instead use this morph for plots.

Hi,

I am raising this issue in Cuis-Smalltalk-Dev, Erudite and hilaire/drgeo.

There exists a git tag for Cuis)Smalltalk-Dev called BaseForCuis6.2.

If I clone the Cuis-S,alltalk-Dev repository and then git checkout BaseForCuis6.2, that works fine, and I get the repsoitory as tagged for Cuis 6.2 including the interesting V3 image for Cuis without "immediate Unicode characters" .

Howver I then subsequently "git clone" the Erudite repository and try to install the Erudite package using

Feature require:'Erudite'

then the Cuis system raises an error and fails to install Erudite.

The message is : Installing [Erudite] requires base system updates to #6247 but this system is updated to #6161. Please install Cuis base system updates and retry. OK'

I tried running

ChangeSet installNewUpdates

that did not help, but in fact an alternative which I am more interested in, is trying to install Erudite "the way it was at the time of BaseForCuis6.2".

Is there a git tag please for the Erudite repo BaseForCuis6.2 so that Erudite can be git checkout'ed using a tag BaseForCuis6.2 so that I can install Erudite in a Cuis 6.2 system ?

The reason I also post this issue in hilaire/drgeo is because DrGeo instructs to intall Cuis6.2 and then to install Erudite (and SVG, Numerics, Parsers etc.)

Thanks,
David Stes

Open the PetitParser tutorial and click on 'Parsing some input' raises the error 'Not enough elements'

It looks like UML is not being parsed in nested book sections.

At first glance it works, however after closing and reopening a UML book, only the UML in the top-level sections are images.

Would you also like to have tables in the Erudite package?

If yes, what should the syntax look like?

Hi.
Error installing PetitParserTutorial.
Petit Parser expected = 1.3
Petit Parser current version (Cuis-Smalltalk /Parsers )= 1.2

Cuis version: #4253

PetitParserTutorial package doesn't load.

Error says: 'Could not find code package file for [PetitParser]. Installation of [PetitParserTutorial] failed'.

This happens after installing Erudite first.

My guess: I think this is a problem of Cuis feature requirement subsystem. Feels like it is looking for a CodePackageFile even when PetitParser package is already loaded in the image.

PetitParserTutorial requires PetitParser 1.2, and PetitParser already installed by Erudite is 1.4

Clicking save-as in the editor seems to remove the language extension from the book. For example, the parser class method is not there in the new class of the book.

The system throws an error when selecting one of the "Read" or "Edit" entries in the Erudite menu.

It complains about 'bad number of arguments' when doing a call to self perform: #markup on an EruditeMarkupGrammar object.

I think the root of the problem is calling perform: with selectors whose methods are AdvisedMethod instances.

To confirm this, I changed a test case in the MethodAdvisersTests class to send perform: #selector instead of sending selector directly to the subject after installing the AdvisedMethod. This results in the same error.

We can change submorphs alignment via using {axisEdgetWeight: ::selector}: . The axisEdgeWeight can be be either a number between 0.0 and 1.0, or one of #columnTop, #rowLeft, #center, #rowRight, #columnBottom. For example, let''s center our submorphs:

axisEdgetWeight should be axisEdgeWeight (extra letter t in original)
