Anyone have any more elegant solutions? Chris has already given a near solution. You just need to "select: #isDigit" on the end of his answer to get exactly what you want. frank

Formatting dates

by blake

Heya, guys-- Converting a Ruby program to Pharo, and one of the things this program does is write a file out by date. The format is "yyyymmdd" (which is my preferred naming convention). In Ruby I have: "%04d" % d.year + "%02d" % d.month + "%02d" % d.day In Smalltalk, the closest I can seem to get to this is: d year asString, (d monthIndex asString padLeftTo: 2 with: $0), (d dayOfMonth asString padLeftTo: 2 with: $0) ...which seems sort verbose. Anyone have any more elegant solutions?

Re: [Pharo-dev] Using Gutenberg

by StÃ©phane Ducasse

Well were are the books you wrote with this wonderful format? The only guy I can consider is sven. Why because he is writing real documentation. Now I'm confident that sevn could write in pier syntax because this is really close to markdown. What is missing is the immediate rendering of pier syntax as in the collabactive book.

Because you learn markdown first but pier syntax predates it. and because like that we have one syntax for everything.

Or why we canât use epub + sigil for example. IT IS NOT A NEW SYNTAX!!! We have this neutral syntax that proved to work for real and we have exporters and with a bit of work we will be able to generate all the formats we want. So if you need epub, add a visitor and all the chapters I'm writing will be in epub too. But I will not work with a syntax that does not let me write book, html, â¦. Why because this is my time.

I donât think that markdown is good for books. Thatâs exactly what I encountered. I wanted to start with this updated version of RBE and wanted to use Gutenberg so it will be possible to put the book on iBook store and Amazon and read it on iDevices and Kindles. But When I started to rewrite latex source in Gutenberg Iâve found that a lot of details are going to be missing, because the is no support in Gutenberg for them. Like what?
