Has anyone else tried using a Mac with Digital Ocean? Pharo runs cross platform, Mac OS X is certainly no problem since that is what most people are using. Now, you are deploying on Ubuntu Linux, which is essentially independent from where you are developing. I am not sure what went wrong, but did you select a 32-bit Ubuntu variant ? What does 'uname -a' say ? Can you copy/paste the literal error ? 64-bit does also work, but you need to do some extra stuff, for a 1st tutorial I would skip that part. HTH, Sven

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

by Bruce Prior

I worked my way through Sven van Caekenberghe's excellent tutorial on building and deploying a web app on Digital Ocean's cloud server. All went well at first, even though Digital Ocean didn't offer a Mac option (I picked Ubuntu Linux). I skipped the Tests and Configuration parts of Sven's tutorial in order to get to the deployment part faster. I thought I could come back to those parts. I was able to get SSH command line access to the new server and loaded Pharo using curl (See Sven's Section 12.3). But when I went to test the setup using # ./pharo Pharo.image printVersion I got an error saying pharo not found even though it was there in the pharo-vm directory. I suspect that my attempt to do all this on an Apple iMac is the problem. Has anyone else tried using a Mac with Digital Ocean?

In my example I did the same mistake, even if you instantiate a RubScrolledTextMORPH the object that processes the keyevents is actually a RubEditingArea, accessible through (RubScollredTextMorph) self textArea.

You can use the power of Inspector! Inspect rubric morph and you will see there is shortcuts tab which lists all assigned shortcuts and if you click on one them a new tab will be opened to the right showing exact place in source code when shortcut is defined and its action.

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

by Johan Fabry

Hi Nicolai, thanks for your answer! 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. > On Oct 28, 2015, at 17:58, Nicolai Hess <nicolaihess(a)gmail.com> wrote: > > > > 2015-10-28 19:59 GMT+01:00 Johan Fabry <jfabry(a)dcc.uchile.cl <mailto:jfabry@dcc.uchile.cl>>: > Hi all, > > I am trying to add a keyboard shortcut to a RubTextEditor.
