HTTPClient and HTTPSocket are gone, fully deprecated. If there is little to no HTTP interaction, I would consider Soup class>>fromUrl: urlObject urlObject asUrl retrieveContents.

Re: [Pharo-project] [squeak-dev] The Inbox: Compiler.quasiquote-eem.248.mcz

by Eliot Miranda

Hi All, I had fun implementing a quasi-quote for Squeak today. This is a convenient way of embedding substrings in format strings (a little like printf), and, because it uses a different quote character, a convenient way of embedding code form other languages in a string literal. An example of the former usage is `hello [#cruel] world` which evaluates to 'hello cruel world' And `Float pi is [Float pi]` evaluates to 'Float pi is 3.141592653589793' An example of the latter use is that one can write `printf("%s: %c\\n", "a string", 'C');` instead of 'printf("%s: %c\n", "a string", ''C'');' This last example shows a limitation; The use of \ to escape characters ($\ $[ and $`) in quasi-quote might not be such a good choice. Anyway I thought I'd put this in the in-box for people to play with and savage. Please let me know what you think, both about the semantics and the implementation. This is a quick hack and I'm sure that there's plenty of scope for clean-up. cheers Eliot On Tue, Feb 5, 2013 at 9:54 PM, <commits(a)source.squeak.org> wrote: > A new version of Compiler was added to project The Inbox: > http://source.squeak.org/inbox/Compiler.quasiquote-eem.248.mcz > > ==================== Summary ==================== > > Name: Compiler.quasiquote-eem.248 > Author: eem > Time: 5 February 2013, 9:54:20.317 pm > UUID: ef044906-3339-48cc-856b-9b5172e3e81b > Ancestors: Compiler-cwp.247 > > Add a quasi-quote form that allows convenient embedding > of substrings within a format string, and provides a > convenient way of embedding literal strings within an > alternative literal string whose string delimiter is different. > > e.g. > `hello [#cruel] world!` > evaluates to > 'hello cruel world'. > > `S1[B1]...SN[BN]SN+1` > > is equivalent to > { 'S1'.
