And - yes that is bad - not all keyboard shortcuts go through KMKeyCombination and KMKeymap. The SmalltalkEditor class defines its own shortcut handler. For exampe: cmd+shift+a -> #argAdvance: This method searches for the next $: followed by a space and place the caret after the space. nicolai

Implementing text navigation shortcuts

by Laura Risani

Hi all, I like to implement a keyboard shortcut for, while editing any text, move the text pointer to the next position after $: . Seems that the base of all text editing is the class #TextMorphForEditView. I see there there is an instance variable for the text. My problem is i can not find a method that tells/sets the current position in the text of the text pointer. I've tried going through the list of methods of #TextMorphForEditView and its superclasses. Also through the one of senders of #arrowRight trying to find the instantiation of #KMKeyCombination needed to implement the existing shortcut "ctrl + right arrow" which jumps to the next position after an space, but i found nothing. Best, Laura

Re: [Pharo-users] [Pharo-dev] [ANN] PUnQLite NoSQL database project updated

by Tudor Girba

Hi Torsten, This sounds very interesting. I tried to play with it on Mac, but I got a bit stuck. Here is what I did: - I downloaded the UnQLite sources from: http://unqlite.org/db/unqlite-db-20130825-116.zip - In that folder I did: gcc -m32 -c unqlite.c gcc -m32 -dynamiclib -o unqlite.dylib unqlite.o - I then copied the unqlite.dylib file in the plugins folder: Pharo.app/Contents/MacOS/Plugins - I started a Pharo 4 image with the corresponding VM - I loaded the stable version of PUnQLite from the ConfigurationBrowser - I executed without errors the code you mentioned: |db| db := PqDatabase open: 'comments.db'. db disableAutoCommit. db transact: [ Object subclasses do: [:cls | | key | key := cls asString. db at: key put: cls comment ] ]. db close. ==> However I do not get a comments.db file/folder, and the Database Browser does not show anything. Am I doing something wrong?

Autoformatting extisting packages

Hi all, How do i apply autoformatting to existing packages? I've read somewhere that this functionality used to be at the refactoring menu, but i can't find it, don't know if it has been renamed or moved. Best, Laura

Code completion differences at browser and workspace

by Laura Risani

Hi all, I've noticed that the code completition tool shows a different list if brought up at a workspace or at a system browser. Particulary workspace's completition list is broader than browser's one. For instance if while writting a method i have already accepted other method names but haven't yet defined them in any class, these selectors are shown in worskpace's completition but don't in browser's. So while at the system browser i have to waste keystrokes bringing up the manually the other completition tool and search in that list the selector i want. So, question : how do i make the completition tool show at system browser the same list that it would show at a workspace? Best, Laura

Re: [Pharo-users] [ANN] PUnQLite NoSQL database project updated

by PBKResearch

Hi Torsten This looks very interesting. I am looking at a project which needs simple persistence, and I was considering MongoDB plus Voyage, which looked like overkill. I shall definitely be trying PUnQLite. I am not yet on Pharo 4; I am using Moose 5.0, which is essentially Pharo 3. To load PUnQLite, I used the Gofer script on GitHub, the only problem being that the config did not load the PunQLite-Tools package; I got that separately by using the Monticello browser. My main purpose here is to tell you about a problem I found when running the 'comments.db' example below. The database was generated as expected, but when I used the Database Browser to examine the results, I found that trying to display the comment for some classes caused a PqFetchError. It affects only a small proportion of classes; going through the alphabetical list in the browser, the first three classes affected are AbstractDistributionMap, AbstractEcryptorDecryptor (sic) and AbstractTimeZone. One curiosity is that, once the debugger window has popped up for one entry and been closed down, the same window appears whichever other entry is selected next. I have deleted and recreated the 'comments.db' file to see if that would clear the problem, but it persisted. This disclosed another curiosity. The 'choose a .db' window that pops up when opening the Database Browser has a button to delete a file, but it did not delete my database file when I tried it; I had to close down Pharo to free the file and then use Windows Explorer. It seems that the problem is one which affects the Database Browser only; I tried a snippet in a workspace which opened the comments.db database and retrieved the entry for AbstractDistributionMap, and it worked correctly. I hope this is enough detail for you to investigate; if not, come back to me.

If you like to use a small RDBMS solution with Pharo then there is the embeddable SQLite shared library and NBSQLite3 project [1] to access it. Combine it with Glorp [2] and you do not have to fight too much with SQL. On the other end of persistency world there are the so called "NoSQL databases" and beside Mongo and all the others that require special setup etc. there is this wonderful small UnQLite embeddable database [3] that similar to SQlite world only requires a simple library. Thanks to Masashi Umezawa there is a nice wrapper for Pharo already to access this tiny embeddable NoSQL database called "PUnQLite" [4] and [5], also including access to the Jx9 machinery of UnQLite. It is really cool that he made this available. This week I updated "PUnQLite" a little bit: - refactored the Native boost wrapper for UnQLite (using shared pools, ...) - documented classes - added a help topic - fixed a bug in cursors when accessing the keys in an empty database - and finally added a small spec based tool to work with a database file (see attached screenshot) One can use it to open an unqlite database, show the key value pairs and remove or add entries. If you are in latest Pharo 4 already you can load all of that right from the config browser. Be aware that you need the external unqlite shared library which is downloaded and extracted into a folder "pharo-vm" when loading the config. For instance on Windows it automagically downloads a file "pharo-vm/unqlite.dll" below your image directory and you just have to copy this shared library file to the folder where your VM (Pharo.exe) resides. Havent tried on other OS platforms. >From the Pharo side using the UnQLite database basically works like having some kind "external dictionary" in a database file. Just run that in a workspace: |db| db := PqDatabase open: 'comments.db'. db disableAutoCommit. db transact: [ Object subclasses do: [:cls | | key | key := cls asString. db at: key put: cls comment ] ]. db close. Then open the "Database Browser" from the world menu and open the "comments.db" file. You can browse the keys and values, remove entries or add new. A filter for the keys is also included. Nothing fancy but hope you like it or find it usable. Couldnt make it to PharoConf 2015 but I hope all participants enjoy their time there.

Re: [Pharo-users] New book for Pharo :)

by Werner Kassens

Hi Ben, i also prefer SCI, although i have another reason <g>, it has less letters than MATH and the letters are positioned nearer to each other on my keyboard (good for my one-handed typing approach). SciTalk is a really nice idea i agree. werner On 01/29/2015 04:19 PM, Ben Coman wrote: > MATH seems to constraining. SCI seems good. And I like that suggestion > for SciTalk.
