convert from VisualWorks to Pharo
Locked
 
|
Hello,
I'm trying to convert some packages from VW to Pharo. For that, I use the technic described in the SCG wiki (using the squeak exporter in visual works and then dragging the .st file in pharo). For some packages it works well. For other, I have syntax errors (that don't really described the problem). In these case, what is the solution ?

The syntax error (with respect to the Pharo parser) is sometimes easy to spot, sometimes not. I think there is way to get a better error review. -- Simon _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

But what generates the error?

I'm not able to tell what is the problem. It seems that the line:
string replaceAll: $ä with: $a. is the origin of the problem. By sending 'proceed' to this syntax error, all ends with success. I have also another question: If in visual works, the package contains extensions to classes that no longer exist in Pharo, what is the solution to port it to Pharo?

Hi Cyrille,
The simplest solution is to rename the classes in VisualWorks and export afterwards. Another solution is create the VW classes in Pharo and move the methods afterwards.

Here is the content of my syntax error window : =================================== performStemming: aString string := aString. self toLowercase. self preprocessing.
self setMarks. self step1. self step2.
self step3. self toLowercase. string := string replaceAll: $ä Argument expected ->with: $a.
string := string replaceAll: $ö with: $o. string := string replaceAll: $ü with: $u.
^string "German includes the following accented forms, ä ö ü
and a special letter, ß, equivalent to double s. The following letters are vowels:
a e i o u y ä ö ü First, replace ß by ss, and put u and y between vowels into upper case. R1 and R2 are first set up in the standard way (see the note on R1 and R2), but then R1 is adjusted so that the region before it contains at least 3 letters.
Define a valid s-ending as one of b, d, f, g, h, k, l, m, n, r or t. Define a valid st-ending as the same list, excluding letter r.
Do each of steps 1, 2 and 3. Step 1: Search for the longest among the following suffixes,
(a) e em en ern er es (b) s (preceded by a valid s-ending)
and delete if in R1. (Of course the letter of the valid s-ending is not necessarily in R1) (For example, äckern -> äck, ackers -> acker, armes -> arm)
Step 2: Search for the longest among the following suffixes, (a) en er est (b) st (preceded by a valid st-ending, itself preceded by at least 3 letters)
and delete if in R1. (For example, derbsten -> derbst by step 1, and derbst -> derb by step 2, since b is a valid st-ending, and is preceded by just 3 letters)
Step 3: Search for the longest among the following suffixes, and perform the action indicated.
end ung delete if in R2 if preceded by ig, delete if in R2 and not preceded by e
ig ik isch delete if in R2 and not preceded by e lich heit delete if in R2 if preceded by er or en, delete if in R1
keit delete if in R2 if preceded by lich or ig, delete if in R2
Finally, turn U and Y back into lower case, and remove the umlaut accent from a, o and u."

So apparently, it is a problem with the input charset of the st file, which the Pharo parser does not recognize. Cyrille, can you execture a 'file -I changeset.st' in a terminal to get the charset? On 25 févr. 2010, at 14:14, Cyrille Delaunay wrote:

I have replaced the only method concerned by hand :)
