Receiving notification of theme changes or changes to syntax highlighting properties
by monty March 20, 2016

March 20, 2016

How can you receive notification of a theme change (like going to or from the Dark theme), or even better, notification of a change to some property of syntax highlighting (like the styling used for string literals)? And what is the preferred way of querying the current syntax highlighting properties? I am using "SHTextStylerST80 new attributesFor: aProperty" now (SHPreferences doesn't provide enough), but there is talk of Shout being removed.

Changes Browser is broken

Today I learned that you can actually lose code in Pharo because the record is not always added to the changes file. Also using the tool is quite a lot of pain, so if you want to recover your changes you have to do a lot of archaeology. I've added several issues and marked most of them as '2 - Really Important', because I think they are (especially for students etc that like to break things), but maybe you don't want it for Pharo 5. https://pharo.fogbugz.com/f/cases/17840/ChangesBrowser-selectAll-DNU https://pharo.fogbugz.com/f/cases/17841/Creating-a-class-from-a-debugger-du… https://pharo.fogbugz.com/f/cases/17842/Recover-lost-changes-doesn-t-recove… https://pharo.fogbugz.com/f/cases/17843/Changes-Browser-doesn-t-recover-cha… Peter

[ANN] FFICHeaderExtractor first milestone (for early code reviewers) [WAS] Can OSProcess functionality be implemented using FFI instead of plugin?
by Mariano Martinez Peck March 18, 2016

March 18, 2016

Hi guys, OK, I have a first working version and so I wanted to share it with you. I have not yet the time to start writing the doc since I just finished the first pass on the code. Tomorrow I will start with the doc. But I thought some of you may be interested in taking a look even without formal "doc" (and some feedback/iteration may avoid re-writing docs..). If you have no clue what I am talking about, then this summary is for you: *----------* *When we use FFI to call a certain library it's quite common that we need to pass as argument certain constants (for example, SIGKILL to kill()). These constants are defined in C header files and can even change it's value in different paltforms. * *These constants also are sometimes defined by the C preprocessor and so there is not way to get those values from FFI. If you don't have the value of those constants, you cannot make the FFI call. * *----------* I have tested the tool in OSX and CentOS using latest Pharo 5.0. It won't work in Windows right now. As usual, all classes and methods have comments and there are enough tests. At the end, I decided the C program will output a very naive Smalltalk literal array kind of thingy. The tool then parses that output and directly creates a init method (which is compiled into the SharedPool class) for that platform which is then called automatically at startup (only if initialization is needed). As for real examples, I started to write constants for libc: signal.h (to use kill()) , wait.h (to use wait() famility), fcntl.h (to use ... xxx()) , and errno.h. You can take a look to the package 'FFICHeaderExtractor-LibC'. Note that for running the tests you need 'cc' findable by path in OSX and 'gcc' in Unix. To load the code in a latest Pharo 5.0, execute: Metacello new baseline: 'FFICHeaderExtractor'; repository: 'github://marianopeck/FFICHeaderExtractor:master/repository'; load. Any feedback is appreciated. I will start writing the doc now. BTW: Big thanks to Eliot Miranda which helped me answering noob questions and providing useful code and guidelines.
