Thanks. > Bruce Just for the record, Pharo runs fine in 64-bit, although for the moment it remains a 32-bit application. There are various ways to install the VM. If you follow my approach using the zero config scripts, and you only need to deploy to a headless server, the following script installs what is needed on Ubuntu: https://github.com/svenvc/pharo-server-tools/blob/master/ubuntu-32bit-suppo… Sven

Attempting Pharo Book #3 WebApp Example on a 64-bit iMac

by Bruce Prior

My problem was that I chose a 64-bit Ubuntu OS when I signed up with the ISP, Digital Ocean. So I started another Droplet at DO and set it up with an Ubuntu 32-bit system. All is well now and everything down to the end of sec. 12 in Sven's tutorial works for me. Now I'll look at Deploying For Production. Many thanks to Sven and Damien for their comments, and to Sven for his fascinating tutorial. Bruce

No... I got it wrong, it was a copy & paste mistake. It should be Zn... because I put them both in the tests to compare. Thank you for noticing. Regards! Esteban A. Maringolo

thanks, so the title should be Base64MimeConverter instead of ZnBase64Encoder. On Thu, Oct 29, 2015 at 5:18 PM, Esteban A.

Esteban, Could you explain line 8 ? why did you use a Base64MimeConverter? thanks. line 8: stream nextPutAll: 'ZnBase64Encoder '; nextPutAll: [ (Base64MimeConverter mimeEncode: ba readStream multiLine: false) ] bench printString; cr.

I also prefer base64 even over native binary storage. I ran a small comparison[1] of speed and size and these were my results.

ByteArray is not pharo-specific, but the syntax is --- I can copy paste base64 from/to outside world. Plus base64 has better tool support in the wild.

Re: [Pharo-users] How to add a keyboard shortcut to Rubric?

by Johan Fabry

Excellent Nicolai, thanks for the detailed answer! Now I have everything working exactly as I want it to be, so Iâm happy :-) (Also, alex, thanks for pointing out the tab in the inspector, but I think I would have not found it since the morph is embedded in a Spec window so it would have been even deeper in the hierarchy.) > On Oct 28, 2015, at 20:04, Nicolai Hess <nicolaihess(a)gmail.com> wrote: > > > > 2015-10-28 23:56 GMT+01:00 Aliaksei Syrel <alex.syrel(a)gmail.com <mailto:alex.syrel@gmail.com>>: > You can use the power of Inspector!

However, apparently the problem is a bit different: the shortcut I wanted to add, cmd-s, already existed but I did not realize it! I want to add cmd-s to save the text to a file, but the editor has auto accept set to true and cmd-s calls accept by default. So adding another cmd-s did not do anything and neither could I see that the existing cmd-s binding was executing some other behavior :-/ > > After seeing this, I expected that I would be able to remove the cmd-s keybinding, using removeKeyCombination: but apparently I cannot (see example below). > > In general, itâs not nice to discover from the code that there are keyboard shortcuts that are not listed in the context menu. The enduser should be able to discover all active keybindings from what is visible in the UI and this is not the case here. Maybe Iâll make a subclass of RubTextEditor that only reimplements buildShortcutsOn: so that it is without all these hidden keybindings. > > But for now Iâll add cmd-d to do save â¦ although thatâs ugly. :-( > > | window text | > text := RubScrolledTextMorph new. > > "define a custom shortcut" > text removeKeyCombination: $s command. > text on:$s command do:[ > text setText: text text asString reverse]. > > window := StandardWindow new. > window addMorph: text fullFrame: (0@0 corner: 1@1) asLayoutFrame. > window title: 'Example'. > window openInWorld. > > @Johan, as above, the "correct" morph for processing the keyevents is the textArea of the RubScrolledTextMorph, > this should work > > > | window text | > text := RubScrolledTextMorph new. > > "define a custom shortcut - notice the call to textArea" > > text textArea removeKeyCombination: $s command. > text textArea on:$s command do:[ > text setText: text text asString reverse]. > > window := StandardWindow new. > window addMorph: text fullFrame: (0@0 corner: 1@1) asLayoutFrame. > window title: 'Example'. > window openInWorld. > ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD and RyCh labs - Computer Science Department (DCC) - University of Chile
