---------- Forwarded message ---------- From: GermÃ¡n Arduino <garduino(a)gmail.com> Date: 2010/6/2 Subject: Re: [squeak-dev] Re: Using WebClient To: The general-purpose Squeak developers list <squeak-dev(a)lists.squeakfoundation.org> Hi Andreas: Thanks by the comments. I will continue with the multipart stuff, because this may become a payed work for a local customer. Indeed I could do the job with other tools but in most of cases that means install a gazillion of different pieces of software of third parts that are complex to make work. I prefer to develop my own solution, even with a bit more of work, but completeley Smalltalk. Then I can deploy on the customer a self containded service that I can extend as the customer need. I'm now reading about multipart/form-data enctype and will try to develop this feature for WebClient (if the customer don't cancel the project). Will send the news. Cheers.

I'll probably finish it today. Again a little question about petitparser: In bibtex I have to parse: "{ here is a string }". I wrote that: $} asParser negate star. But, in the string between { and } can contain the $} character, like that: { Mart{\'\i}n }. I don't know how I write that...

Re: [Pharo-users] Help with petitparser

by Lukas Renggli

I've added case-insensitive matching to the latest version of PetitParser-lr.173. I am not entirely happy with the implementation itself, but the API is ok and will be stable. By default all matches are case-sensitive, but you can tell character and string parsers to match case insensitive: " matches 'a' and 'A' " $a asParser caseInsensitive " matches 'abc', 'AbC', 'Abc', ... " 'abc' asParser caseInsensitive Hope this helps.

Help with petitparser

by Adrien BARREAU

Hello, I need some help with petitparser. I encountered 2 problems. Here they are: - I don't find to way in petitparser to: parse every string except a list of strings. For example, I want to parse all string except 'string' and 'STRING'. - I don't find a way to parse a string without taking care of its case. For example, I want to parse 'string', 'STRING', 'String', 'stRINg', etc ... I hope you'll can help me :) Adrien. _________________________________________________________________ La boÃ®te mail NOW GÃ©nÃ©ration vous permet de rÃ©unir toutes vos boÃ®tes mail dans Hotmail ! http://www.windowslive.fr/hotmail/nowgeneration/
