How to capture the execution of a playground?

by Offray Vladimir Luna CÃ¡rdenas

Hi, I would like to store the object resulting from executing a playground. This would imply two steps: - Knowing that the playground content was executed (via the play button or its shortcuts Ctrl + Shift + g or Ctrl + g). - Getting the results of that execution. For example if the result at the end is a string or a dictionary, I would like to get that string or dictionary. Any pointers on how to make that will be welcomed. Cheers, Offray Ps: I still get lost when I search by myself trying to answer questions like the ones above. I imagine that in some way is related with evaluationAction and presentations, by looking for the source code of "do it and go", but still I can't get a functional code snippet to start prototyping.

Proof of Concept: FileTree and Fossil

by Pierce Ng

Hi all, I have written a simple integration of FileTree with Fossil to avoid the 2-step Pharo- and shell-level work to add/delete/commit files. At the operating system command prompt, init a new Fossil project: os% mkdir ~/repo os% cd ~/repo os% fossil init myproject.fossil project-id: 3c05c3016eeabf8e87816ee218c6a86d3c87b950 server-id: ff42bc86dba1a26b1d94b64685f7c09d02581617 admin-user: laptop-user (initial password is "1fe2ff") Open the repository: os% mkdir ~/myproject os% cd ~/myproject os% fossil open ~/repo/myproject.fossil In a fresh Pharo 6 image - I used v60411 - install FossilFileTree: Metacello new baseline: 'FossilFileTree'; repository: 'github://PierceNg/FossilFileTree'; load. Write code in Pharo. Open Monticello Browser. Add a "fossilfiletree" repository, using ~/myproject as the directory. Save to said repository from within Monticello Browser. Done.

Re: [Pharo-users] 4 new chapters for new book on OOP and Design

by Peter Uhnak

Hi Stef, I also noticed this but thought the problem was on my end. _All PDFs_ (books, mooc, ...) here https://ci.inria.fr/pharo-contribution/view/Books do not work in my Google Chrome (version 57). PDFs on different sites work fine. Looking at console I see some errors related to content security policy.. maybe they are bit more uptight about ensuring CSP?

Windows automation [os-windows]

by lw1990

I'm interested in using pharo to automate the windows operating system through the windows API. I found a package called os-windows, which has a lot of this functionality but also a lot is missing, I want to help add more - how is this done? Specifically I want to be able to: Move the Windows cursor on the desktop relative to the screen size Move the Windows cursor relative to the active window on any active window, not just the console Monitor all hardware keyboard activity (respond to hotkeys in any application) Send keystrokes to any target window or window control (such as an edit control) Get control information from external windows, such as the contents of an edit control, or the label of an edit control, or the hwnd of the edit control, etc. Ability to do DllCalls (which opens a lot of functionality in Windows, such as sending windows messages that can activate menu items in third party desktop applications). All of this functionality and more comes from the windows scripting language AutoHotkey (https://autohotkey.com/) I'm looking to make much of the AutoHotkey functionality available in Pharo, so that I can use Pharo instead of Autohotkey. AutoHotkey is implemented under-the-hood with the C language and is open source, so I can see how they made their functions work, I would like to port this to Pharo. Can anyone could shed some light on this process, is it even practical to do this? -- View this message in context: http://forum.world.st/Windows-automation-os-windows-tp4936229.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
