Charting graphs
by Alexandre Bergel Jan. 6, 2015

Jan. 6, 2015

Hi! RTGraphBuilder went through major improvements. - min and max may be specified. - plugins to add some decoration (average line, standard deviation range, ticks lines, â¦) Here are some examples, with some examples, which should illustrate these points: Is obtained with: -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= | b ds | b := RTGrapherBuilder new. ds := RTDataSet new. ds points: (0 to: 100 by: 0.1). ds y: [ :x | (0.1 * x) sin ]. ds noDot. ds interaction popupText: 'sinus'. ds connectColor: Color blue. b add: ds. ds := RTDataSet new. ds points: (0 to: 100 by: 0.1). ds y: [ :x | (0.2 * x) cos * 2 ]. ds noDot. ds interaction popupText: 'cosinus'. ds connectColor: Color red. b add: ds. b minY: -4. b maxY: 4. b minX: -25. b build. -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= b := RTGrapherBuilder new. ds := RTStackedDataSet new. ds interaction popup. ds points: #(600 470 170 430 300). ds barShape width: 20; color: Color lightGreen. b add: ds. b axisX noLabel; noTick. b axisY noDecimals. b addPlugin: RTMeanDevVarPlugin new. b build -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= Another example: -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= b := RTGrapherBuilder new. b extent: 300 @ 200. 5 timesRepeat: [ ds := RTStackedDataSet new. ds noDot. ds points: ((1 to: 500) collect: [ :i | 50 atRandom - 25 ]) cumsum. ds connectColor: Color green. b add: ds. ]. b addPlugin: RTMeanDevVarPlugin new. b build. -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= -=-=-=-=-=-= The plugin framework exposes to a plugin all the necessary to define a whole range of decorations. For example, variable average lines, linear regression should be trivial to add... Happy new year!

Object>>ifNilOrEmpty: aBlock
by Sebastian Sastre Jan. 5, 2015

Jan. 5, 2015

Hi guys, Iâve started to use this little one: Object>>ifNilOrEmpty: aBlock self ifNil: [ ^ aBlock value ]. (self isCollection and: [ self isEmpty ]) ifTrue: [ ^ aBlock value ]. ^ self. It allows you to do the widely known JavaScript one-liner: var stuff = this.thing || âsome default value for when this.thing is undefined, null or an empty stringâ. but in smalltalk in this way: stuff := self thing ifNilOrEmpty: [ âsome default value for when self thing is nil or an empty stringâ ] simple thing feels practical and nice :)

Wrapping RegQueryValueExA in NativeBoost
by Torsten Bergmann Jan. 5, 2015

Jan. 5, 2015

Hi, Happy new year! I try to wrap some API methods using NativeBoost to access Win32 Registry and broaden the Pharo support for Windows. Currently I'm already able to - create registry keys (RegCreateKeyA API) - open registry keys (RegOpenKeyExA API) - delete registry keys (RegDeleteKeyA API) - close registry key handles (RegCloseKey API) Now I additionally want to query some keys using the "RegQueryValueExA" API (http://msdn.microsoft.com/en-us/library/windows/desktop/ms724911%28v=vs.85%…) As I tried an example in an elder Smalltalk/MT first (see attached) I know it is working from the Win32 API side. My NativeBoost definition in Pharo for wrapping the function looks like this (similar to MSDN): regQueryValueExA: hKey with: lpValueName with: lpReserved with: lpType with: lpData with: lpcbData <primitive: 'primitiveNativeCall' module: 'NativeBoostPlugin'> ^ self nbCall: #(LONG RegQueryValueExA( HKEY hKey, LPCTSTR lpValueName, LPDWORD lpReserved, LPDWORD lpType, LPBYTE lpData, LPDWORD lpcbData)) module: #advapi32 But when I call it I get a "Generic error" thrown by NB and independent how hard I try I can not get this call to work in NativeBoost. I checked all arguments, checked the type definitions (pool WinTypes which is similar to NBWinTypes), played with options, ... but was not able to find out what I'm doing wrong in Pharo. Meanwhile after investing several days of my spare time it looks like I cant "see the wood because of all the trees". I would really appreciate if someone with enough knowledge of NativeBoost could have a second look to point my into the right direction. To reproduce: ============= - use a fresh Pharo4.0 Latest update: #40428 - open World menu -> Configuration Browser and load "OSWindows" project - go to class WinRegistry - there is the NativeBoost API definition in method #regQueryValueExA:with:with:with:with:with: - and a method #example2 that calls this in a similar way as in my Smalltalk/MT example (if you try this example you get the "Generic error") Many thanks in advance! Bye T.
