[Ann] Fog 1.0.0-beta

by Santiago Bragagnolo

Hi All! I have being working on releasing versions (i should do it more often). I am happy to announce Fog v1.0.0-beta. I think I found a API that i like enough. So, i took the courage to pass to 1. Thew new version changes many things: Redefines the roll of the session, it minimize the roll of the connection, it cleans up the code, it defines a more verbose but less magic API. It generates proxies for the contracts. It supports now all the types including: maps and arrays. Goodnight :) Santiago Fog Pharo Ethereum Driver Fog is a library that allows the user to connect to an ethereum based blockchain data base. Is based on the Javascript canonical implementation done by Ethereum community Ethereum Javascript API <https://github.com/ethereum/wiki/wiki/JavaScript-API>. <https://github.com/smartanvil/Fog#dependencies> Download code <https://github.com/smartanvil/Fog#iceberg--baseline>Iceberg / Baseline Metacello new baseline: 'Fog'; repository: 'github://sbragagnolo/Fog/src'; load.

Who said anything about deleting any numbers? The code fragment I posted did not delete any numbers; it merely made a new array with everything that was not #+. In the original post there were no strings. (By the way, you wrote "trailing" where you meant "leading".)

Thinking about this functionally, you want to sum the array elements that are not + . So, (array select: [:each | each ~~ #+]) sum The *best* approach is not to put the + symbols into the array in the first place.
