Re: [Pharo-users] what to use for simple parsing
Sure works. Regex '((XXX Logical Channel) ([0-9])) on (((Upstream)|(Downstream)) ([0-9])) on ((chassis) ([0-9])), ((slot) ([0-9])), ((mac) ([0-9]))' asRegex But in PP, things were more comple and there were a lot of them, so: line ^ temperatureStatusDescrEntry token asParser / temperatureStatusValueEntry token asParser / temperatureThresholdEntry token asParser / temperatureLastShutdownEntry token asParser / temperatureStateEntry token asParser and things like temperatureStatusDescrEntry ^ temperatureStatusDescrOidPrefix, oidIndex, space, equals, space, stringType, space, displayStringValue. made my day much easier. Especially when I had all the tokens I needed: gauge32Type ^'Gauge32:' asParser flatten == [:str | #gauge32]. Not sure it would have been as flexible with a SmaCC (I am not familiar with SmaCC but used Lex/Yacc|Bison in another life). Phil

Re: [Pharo-users] what to use for simple parsing
I used Regex at first to do the job but it turned into an unholy mess (not that it couldn't parse what I needed) and PetitParser was there. it really depends how you approach this. For example in my case I quickly found out that would be insane to put everything in a single string, so I broke the single string to smaller ones and resynthesised it. Each string had a very simple regex quite easy to read if one is familiar syntax. And as Damien said you could extend String to a more flexible object, but then you get in the realm of SmaCC/ PettitParser. I chose SmaCC because it already offered solution to my problem. But for the title of this thread simple parsing I think regex is a very good choice depending on your demands.

Re: [Pharo-users] Oracle on Linux
This discussion about database connectivity feels like the early days of JDBC. Things got solved when people wrote the type 4 drivers in Java, making it all nice to use and all.

Not sure it would have been as flexible with a SmaCC (I am not familiar with SmaCC but used Lex/Yacc|Bison in another life). SmaCC is a lot (and I mean a lot) simpler than Flex/bison, especially for the interaction between Flex and Bison (in short, SmaCC infer all the token/keyword stuff as well as the api between the two objects, behaving like a scannerless system). For everything like keywords, for example, you don't even bother with the token: Gauge32Type: Gauge32: { #gauge32 } ; And of course you would: TemperatureStatusDescrEntry : TemperatureStatusDescrOidPrefix OidIndex Space = Space StringType Space DisplayStringValue (Everytime I read PetitParser code, I see the SmaCC grammar, usually in a more verbose form (asParser, asToken)... ) Some of the benefits of SmaCC are not that obvious in fact. Coming from the Flex/Bison world, what is striking is the multithreading ability of the SmaCC parser infrastructure: they have no global/shared space and you can create as many instances of them as you like, as often as you like... A second benefit, but harder to use, is the AST node automatic generation, with the api, an equality and visitors: this makes all the code appearing behind an SmaCC parser very regular. However, if you derive on a regular basis grammars, the SmaCC API is not designed for that. It could do it (you could maybe include other grammars, for example), but nobody has expressed that need :) Thierry

[Pharo-users] Glorp with PostgresV2 on Pharo 4
I'm on a roll. :-) I've written another blog post on installing Glorp with PostgresV2 on Pharo 4. To avoid this message looking like spam mail promoting my blog and devoid of content, here's the slightly edited blog post, in its original Markdown format sans JSON metadata. Outside of Smalltalk, create the database 'sodbxtest', user 'sodbxtest' with password 'sodbxtest': # su postgres -c psql postgres=# create role sodbxtest with password 'sodbxtest' login; CREATE ROLE postgres=# create database sodbxtest; CREATE DATABASE postgres=# \q # In Smalltalk, firstly, install PostgresV2: Gofer it smalltalkhubUser: 'PharoExtras' project: 'PostgresV2'; package: 'ConfigurationOfPostgresV2'; load. ((Smalltalk at: #ConfigurationOfPostgresV2) project version: '2.4') load. Open Test Runner and runs the PostgresV2 tests. On my Linux Mint machine, using a vanilla PostgreSQL 9.3 installation, 23 of 24 tests passed, and TestPGConnection#testNotify2 erred. Now that we know the PostgresV2 driver can talk to our database, using the Monticello browser, open the PostgresV2 repository and load the package GlorpDriverPostgreSQL. Here I had to edit NativePostgresDriverconnectionArgsFromCurrentLogin: to comment out the second last line: connectionArgs clientEncoding: aLogin encodingStrategy asSymbol This is because GlorpDatabaseLoginResource classdefaultPostgreSQLLocalLogin does not specify encodingStrategy, meaning it is nil and will respond to #asSymbol with DNU. Next, in a playground, execute the following: GlorpDemoTablePopulatorResource invalidateSetup. GlorpDatabaseLoginResource defaultLogin: GlorpDatabaseLoginResource defaultPostgreSQLLocalLogin Open Test Runner and run the Glorp tests. Tested on Linux Mint 17.

Here I had to edit NativePostgresDriverconnectionArgsFromCurrentLogin: to comment out the second last line: connectionArgs clientEncoding: aLogin encodingStrategy asSymbol This is because GlorpDatabaseLoginResource classdefaultPostgreSQLLocalLogin does not specify encodingStrategy, meaning it is nil and will respond to #asSymbol with DNU. Yes, we have to fix that, but you also set it manually, no real need to patch the code: createLogin ^ Login new database: PostgreSQLPlatform new; username: 'sven'; password: ''; connectString: 'localhost:5432_sven'; encodingStrategy: #utf8; yourself Interesting articles !

Hi Mariano, Chatting on IRC about Quuve.. We are curious about the look-like-desktop-application screenshot of Quuve. Is the screenshot from a web application or a Dekstop one? Based on Pharo?

[Pharo-users] Spec with dynamic tabs
Hi to all, I'm working with Spec and appreciate the modularity a lot. However, I had some difficulties to discover, how I can have a dynamic widget in a tab. Plugging together the TabsExample and the DynamicWidgetChange didn't work either. In the end I discovered the flaw: - In DynamicWidgetChangechange the last line from self openWithSpec to self buildWithSpec . The DynamicWidgetChange example works as before. But now also the following works (I propose to enhance the example): - Add a method dynamicTab | tab | tab := self newTab. tab label: 'Dynamic'; icon: Smalltalk ui icons nautilusIcon; model: (DynamicWidgetChange new). ^ tab to DynamicWidgetChange. - add a line addTab: self dynamicTab to DynamicWidgetChangepopulateManager Now you can dynamically change the widgets in the fourth tab.

Re: [Pharo-users] Bytecodes in Nautilus
In other IDE tools that nautilus you can't see anymore the bytecodes though. Yes, we need to streamline all the tools: We need these things to have *one* definition: adding it once should add it to all tools. not necessarily. It should be possible to customise. 2015-04-01 8:06 GMT-07:00 Sean P. DeNigris s...@clipperadams.com mailto:s...@clipperadams.com: Hmm... I found it in the method pane's context menu.

Re: [Pharo-users] Oracle on Linux
Norbert, OpenDBXDriver worked for Oracle in Linux. Not sure the state about right now (FFI status etc), but with some work it should work.
