[ANN] DicThesaurusRex - Spelling correction and thesaurus for Squeak
by Michael Perscheid 23 Sep '13

23 Sep '13

Hi all, we'd like to announce our "DicThesaurusRex" project: This dictionary and thesaurus extension allows Smalltalk developers to benefit from spelling correction and synonym search within source code. It optionally extends code editors with a spelling correction that underlines unknown terms and typos. These annotations can either be corrected with suitable suggestions or always ignored in case of well-known abbreviations. Moreover, the thesaurus integration provides helpful advice during searching and programming. For example, the source code search has been extended to look also for similar terms and synonyms. As a result, the search presents developers not only exact but also semantic matches. For more information, please visit the following project page: https://www.hpi.uni-potsdam.de/hirschfeld/trac/SqueakCommunityProjects/wiki… DicThesaurusRex has been developed as part of our software engineering I course at the Hasso-Plattner-Institute, University of Potsdam (summer term 2013). We'd like to thank the following students: * Daniel Neuschäfer-Rube * Suhanyaa Nitkunanantharajah * Jaqueline Pollak * Jakob Reschke Best regards, Michael --- Michael Perscheid michaelperscheid(a)googlemail.com http://www.michaelperscheid.de/

Serial port write freezes the VM
by mactro 10 Sep '13

10 Sep '13

Hi, I'm developing a mod for Scratch that will allow controlling an educational robot via Bluetooth. I'm using SerialPort2 class that is included in Scratch plugin and allows opening ports by name. Everything works fine BUT, when I send commands in a loop, and the connection is lost (i.e. the robot was powered off), the VM freezes. I tried forking the port nextPutAll like that: timer := Delay forMilliseconds: 1000. port := SerialPort2 new. port openPortNamed:'COM14' baud:57600. process := [port nextPutAll:'test'. Transcript show:'port'.] forkAt: 1. [timer wait. Transcript show:'delay'. process terminate.] forkAt: 7. but with no result. Is there any way to write to a serial port with timeout? mactro -- View this message in context: http://forum.world.st/Serial-port-write-freezes-the-VM-tp4707333.html Sent from the Squeak - Beginners mailing list archive at Nabble.com.
