Re: [Pharo-users] Telnet client

by Sean P. DeNigris

Finding old ( and sometimes new ;-) ) Squeak code is a bit of an art. I find the Nabble search of all Smalltalk mailing lists (or you can restrict to sub groups/lists e.g. just Pharo) the best starting point (http://forum.world.st/) Searching on "telnet" produced a link to the code for the Telnet project you found (the thread is called "Net::Telnet equivalent"). Also, a google search on "squeak smalltalk telnet" produced the following additional leads: * Download some old images; "December 2004... Squeak has built in a very basic telnet client" http://wiki.squeak.org/squeak/1523 * look at the Curl plugin; "adds an new repository type that uses the Curl Plugin... supports TELNET http://www.squeaksource.com/monticellossl" HTH, Sean -- View this message in context: http://forum.world.st/Telnet-client-tp3171716p3172111.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Telnet client

by Aidan Gauland

Hi, I want to create a MUD <http://en.wikipedia.org/wiki/MUD> client (a client for games played over Telnet) with Pharo, but I'm stuck on how best to use Pharo as a Telnet client. I've heard of the cURL plugin, but I'm not sure if that can be (easily) used for anything other than file transfers. Even if I built and installed it, I'm not confident I'd be able to tell for certain whether I can use it in the way I want. I also found this <http://map.squeak.org/package/14bcecc6-dbb8-4866-bb0c-25278ca882ba>, but that's about eight years old and its homepage link is dead, so it doesn't look too promising. I found TelnetProtocolClient in the Pharo image, but that does not seem to be at all what I need. Can someone with experience with telnetting from within Pharo/Squeak point me in the right direction? Thanks, Aidan

Re: [Pharo-users] Numbers showing up in Transcript

There is issue 2610, but it is 'closed'. The closing comment, by marcus.denker, is: "I think this has been fixed in 1.2" I can't tell if it is fixed on 1.2 cos I don't know how to turn this behavior on? What setting is it? I can reproduce it on 1.1 with these steps: 1) Open the the Transcript window 2) Open a Shout Workspace 3) type a ( or [, (or any of the special characters that automatically display the 'closing' character), then move the cursor with the right or left arrow key The numbers that show up in the Transcript are the column positions of the characters. It appears to be some debugging code left in. If I wanted to find where this bug is myself, where would I start to look? Can you give me a hint? *** Another question: How can I search the source code in the image for a particular string?

Re: [Pharo-users] minimal pharo image

by Adrian Lienhard

Hi Annick, You may also want to try ScriptLoader new cleanUpForProduction; cleanUpForRelease This shrinks a 1.0/1.1 image to 7MB or less IIRC (don't know the size for the current 1.2).
