Maybe also OGDF (http://ogdf.net/doku.php) could be used if you are ok with GPLâ¦ they have their own graph format so there could be some interaction. Peter

left-pad.io

This is a really great joke: > http://left-pad.io/ <http://left-pad.io/> But should you feel the need to implement this extremely valuable web service yourself, here is how you could do it in Pharo (error handling is not 100% bullet proof, this is just a quick demo, but you get the idea): 'paddin'' oswalt' padLeftTo: 68 with: $@. (ZnServer startDefaultOn: 8080) onRequestRespond: [ :req | | str len ch | str := req uri queryAt: #str ifAbsent: [ '' ]. len := req uri queryAt: #len ifAbsent: [ '' ]. len := Integer readFrom: len ifFail: [ 0 ]. ch := (req uri queryAt: #ch ifAbsent: [ ' ' ]) first. ZnResponse ok: (ZnEntity text: (str padLeftTo: len with: ch)) ]. ZnClient new host: #localhost; port: 8080; queryAt: #str put: 'paddin'' oswalt'; queryAt: #len put: 68; queryAt: #ch put: $@; get. $ curl 'http://localhost:8080/?str=paddin%27%20oswalt&len=68&ch=@' Of course, if you are really going this into production, you'll have to pay me and Pharo the necessary royalties ;-) Sven PS: Returning a JSON (which does not really make sense here) is left as an exercise.

Pharo days 2016, driving from the Netherlands
by Stephan Eggermont March 28, 2016

March 28, 2016

I've been looking at options to get to Namur from the Netherlands. My current plans are to drive by car from Den Bosch on thursday morning, and drive back friday evening, as it would be twice as fast as going by public transport. Anyone else from the netherlands going in that direction? Or want to share a ride? Stephan Eggermont

Making STON exportation lighter
by Offray Vladimir Luna CÃ¡rdenas March 26, 2016

March 26, 2016

Hi, I'm using STON as my notebook storage file format for grafoscopio[1]. One example of such notebooks is at [2], but they grow large easily. That's because STON serialize a lot of information of each node. A snipped of such info is something like [3], showed at the end of this mail. I remember that someone told me about a way to store only the #string part of the Text node, without any #runs or #values information in STON. How can this be done? Thanks, Offray Extra links and info: [1] http://mutabit.com/grafoscopio/index.en.html [2] http://mutabit.com/repos.fossil/grafoscopio/doc/tip/Docs/Es/Tutoriales/tuto… =[3][STON code sniped]======= GrafoscopioNode { #header : 'LecciÃ³n 1: Bienvenida', #headers : OrderedCollection [ ], #key : '', #body : Text { #string : '\"Hola!, Soy el profesor Stef.
