Re: [Pharo-users] RewriteToolbuilder question

At first, I was not able to reproduce the error, but then I realised that you probably don't save the content of lower left and right parts (`@.Statements).Use cmd+s to save changes. The error is raised because parser tries to parse the old code (same as in upper left part) with a method intended for rewrite rules. That should fix it. If you have any other questions related to RewriteTool don't hesitate to ask. 2017-06-07 19:25 GMT+02:00 werner kassens <wkassens(a)libello.com>: > Hi Mark, > the code from Number>>raisedTo: > > aNumber isInteger ifTrue: [ > "Do the special case of integer power" > ^ self raisedToInteger: aNumber]. > aNumber isFraction ifTrue: [ > "Special case for fraction power" > ^ (self nthRoot: aNumber denominator) raisedToInteger: aNumber > numerator ]. > self < 0 ifTrue: [ > ^ ArithmeticError signal: 'Negative numbers can''t be raised to > float powers.' ]. > 0 = aNumber ifTrue: [^ self class one].

Now what would be really cool is a metalink to bring up a debugger for the next click on a button, to help learn how the system implements that feature. cheers -ben

Though the URL is strange (the json part). What do you get as response ? Maybe the authentication just fails. Or you made some other mistake ? I would personally never write JSON manually, but like this: STONJSON toString: { #authToken->'foo'. #payLoad->({ #name->'test'. #content->'something' } asDictionary) } asDictionary. Or this: (NeoJSONObject new authToken: 'foo'; payLoad: (NeoJSONObject new name: 'test'; content: 'something')) asString. Different styles/frameworks, same result. Sven

I don't know much about RewriteToolbuilder, so probably won't be the one to give a proper answer, but to help someone else answer... could you narrow down which video with a link? cheers -ben On Thu, Jun 8, 2017 at 12:05 AM, werner kassens <wkassens(a)libello.com> wrote: > Hi, > i followed the video and opened the RewriteToolbuilder on some code in > pharo4.0. i then tried to keep things simple and made a > transformationrule,which i thought would not change anything, by just > copying "â@.Statements." into the lower left & right panels (without the " > of course).i then press 'generate rule' and get a 'Syntax Error: end of > Statement list encountered' with this specification: ^ ArithmeticError > signal: 'Negative numbers canEnd of statement list encountered -> ''t be > raised to float powers.' . but this part of the code in the upper left > panel is just a copy of some unchanged standard pharo4.0 code. where did i > go wrong? > werner > > >

RewriteToolbuilder question

by werner kassens

Hi, i followed the video and opened the RewriteToolbuilder on some code in pharo4.0. i then tried to keep things simple and made a transformationrule,which i thought would not change anything, by just copying "â@.Statements." into the lower left & right panels (without the " of course).i then press 'generate rule' and get a 'Syntax Error: end of Statement list encountered' with this specification: ^ ArithmeticError signal: 'Negative numbers canEnd of statement list encountered -> ''t be raised to float powers.' . but this part of the code in the upper left panel is just a copy of some unchanged standard pharo4.0 code. where did i go wrong? werner

ZnClient: how to emulate a curl command

by Offray Vladimir Luna CÃ¡rdenas

Hi, I'm prototyping some integration between Fossil and Pharo for the creation of dynamic distributed web sites [1]. Now I would like to send some messages to store serialized STON domain objects as Fossil wiki pages. The command that makes this, using curl, is: curl -H "Content-Type: application/json" -d '{"authToken": "mytoken", "payload": {"name": "foo", "content": "bar"}}' http://localhost:8081/json/wiki/create and I thought that a similar command would be the one at [2], but there is something about ZnEntity that I'm not understanding. How can I replicate the curl command using ZnClient? [1] http://smalltalkhub.com/#!/~Offray/Brea [2] http://ws.stfx.eu/D61ZOA1LEQNG Thanks, Offray
