Got ZnCharacterWriteStream did not understand #greaseNext:putAll:startingAt: while storing a Canvas on a file

[vitormcruz]

Pharo 11, Windows, using Seaside 3.5.9

While trying to build a WAHtmlCanvas and storing it in a file, I got a "Instance of ZnCharacterWriteStream did not understand #greaseNext:putAll:startingAt:".

The code used to generate the file is:

	aFile writeStreamDo: [ :aFileStream |
		WAHtmlCanvas builder 
			documentClass: WAHtmlDocument ;
			rootClass: WAHtmlRoot;
			fullDocument: true;
			rootBlock: [ :root | root style: self style ];
			render: self on: aFileStream.		
	]

The error stacktrace is:

Hi Vitor, To allow this, we should add the Grease extension method that is on WriteStream to the Zinc stream classes. Add this instance method to ZnEncodedWriteStream greaseNext: anInteger putAll: aCollection startingAt: startIndex "Store the next anInteger elements from the given collection." ^ self next: anInteger putAll: aCollection startingAt: startIndex There are more Zinc classes where this should be added to make it complete, but I think this will solve your problem. Greetings, Johan

Hello,

My workaround for now was to create a String on memory and then write it on the file, which for my use case is fine:

| html |

html := String streamContents: [ :s |
WAHtmlCanvas builder 
	documentClass: WAHtmlDocument ;
	rootClass: WAHtmlRoot;
	fullDocument: true;
	rootBlock: [ :root | root style: self style ];
	render: self on: s.	
].

aFile writeStreamDo: [ :aFileStream | 	aFileStream nextPutAll: html ].
