AFAIK, Cairo uses freetype library for rendering fonts. Thatâs why Igor spent some time making sure that freetype library is not loaded twice (one for the plugin and one other for athens). So, it should be the same external library, but probably not the same Pharo code.

Re: [Pharo-dev] What Logging framework for Pharo

by stepharo

You see if people using logging frameworks would have look for real at Beacon or systemLogger and add one single appenders and publish the code then we would have more of them. We will merge Beacon and SystemLogger with Doru and Norbert and we will slowly add some backends.

Hi guys As a general point of view, often the discussions in this mailing-list are comparing Pharo with projects where - people really produces open-source software and share it for real (by opposition as talking nicely close the fireplace with friends). - it often sounds like we should stop doing things just because people already did something else. - if I would really read these discussions I would drop everything and go do something else. - lot of money have been spent So as a conclusion: - ask yourself what you did for Pharo recently (not just to get money for you) but for the community in terms of open-source software, documentation, bug fixes, blog entries.... - what will you do to change the situation by helping Pharo? Not just using it! Sorry to look harsh but you often kill my fun and energy with strange expectations. We have one and half full time engineer working for Pharo now. And we are pretty successful. Now imagine how pharo would look like if you would participate for real each at its own degree Stef

Phil as usually (sadly) with the loggin framework rant people are confusing logging in the image and outside. WE MUST HAVE A LOGGING infrastructure and it will not be 'J4log' whatever. I want to log compiler error and be able to click on them and jump in the debugger. Right now I can only see errors if I open a transcript and look for strings!!! Now if we would all use the time to write mails to write code....

Appenders in Log4J describe an end point to send the log data/ event object to. So you can have a rolling_file , socket TCP connection, MQ , DB table , console ... any you need, many already provided with their custom code to pipe the info to the end point. Appenders are now configurable ( in code ) typically in XML to be able to pipe it to a file in Production / or a DB . While in dev it is to the console. You can have the same log sent to multiple Appenders with events filtered logically for each of them, with one of the Appender getting the whole dump of events. The critical issue in logging is performance impact of logging too much. On Tue, Jan 13, 2015 at 5:46 PM, stepharo <stepharo(a)free.fr> wrote: > > These are nice.

The problem is that after you have to deselect the expression because else you lose it and this is really annoying. I think that enter should deselect the current expression and paster the result on the following line.
