Re: [Pharo-users] OSProcess on Windows

by Bob Cowdery

Hi Carlos Well, I think frustration is starting to creep in now. Everything I touch seems to croak in some way. I loaded ProcessWrapper as it seems to be the more recommended way on Windows. Still didn't get a plugin with it. Noted that 'ProcessWrapper downloadPlugin' is supposed to do that. That didn't work as it falls over on 'Utilities informUserDuring: '. Even when I took that out of the source it still fell over. Downloaded the plugin source and tried to build it but its missing libraries and I don't know which ones. Also it has a header file which can't be generated so I made one up but probably got it wrong. Oh, well, guess I will press on a bit longer.

OSProcess on Windows

by Bob Cowdery

Does anyone use OSProcess on Windows? If so can you tell me how to make it work please. OSProcess thisOSProcess command: 'cmd.exe /C notepad' Fails in two ways. It tries to output a message to stderr but fails to do so. The message it tries to output just says: "nextPutAll: 'cannot execute cmd.exe /C notepad'". I also tried to open a console with: OSProcess thisOSProcess openConsole but that seems to do nothing and gives no errors. Any help very welcome. Regards Bob

Re: [Pharo-users] VM/Settings for Deploy

by Sven Van Caekenberghe

Laurent, Mariano, Thanks for the reply. I read the various threads you both pointed to. This is not a good situation. A good VM (stable and performant) is absolutely critical to Smalltalk/Squeak/Pharo's success. A 30% speed difference due to some secret compiler settings is very scary for what is essentially an open source project, although I also understand that some people want to get some money back for their efforts. I can't imagine that recompiling the Linux kernel, Apache or PostgreSQL with some secret compiler settings or even another compiler would make so much difference versus the open way (although some minor speedup by tuning compilation to specific hardware is to be expected). I think (and Stef suggested as much since he mentioned buying the Intel C compiler) Pharo needs to deal with this to fullfill its mission of offering a free and open source attractive platform to build and deploy mission critical Smalltalk applications. On the other hand, I wouldn't mind paying a reasonable license/support fee if that would benefit the community as a whole at the same time.

Re: [Pharo-users] Finding packages

by Bob Cowdery

Hi Adrian Not having much luck really. I've tried two versions of OsProcess, one I found from a previous Pharo message and the other from your link. Both fail to load with Syntax errors and leave all the categories installed but no code. This is the error which was in UnixProcess (a bit odd seeing as I'm on Windows). I also loaded the OsProcessPlugin but that appears to require compiling according to the readme. This all seems to be much harder than it should be, or maybe it's just me. Regards Bob argsAsFlatArrayAndOffsets: anArrayOfNullTerminatedStrings "Given anArrayOfNullTerminatedStrings, flatten the array into a string buffer, leaving space at the beginning of the buffer for a list of C pointers. Answer the string buffer and an array of address offsets. The address offsets may later be converted to C pointers and overlaid on the beginning of the buffer, resulting in a data structure which can be treated as a C array of strings suitable for use as a Unix argv vector." "OSProcess thisOSProcess argsAsFlatArrayAndOffsets: (UnixProcess arguments collect: [:e | e, (Character value: 0) asString])" | offset arraySize flatStringArray ws addresses | "Preserve offset space to hold address pointers." offset := (anArrayOfNullTerminatedStrings size + 1) * self processAccessor sizeOfPointer.

Re: [Pharo-users] Finding packages

by Adrien BARREAU

The first thing I do (don't know if it's the best idea) when I am searching for a package is to take a loot at www.squeaksource.com and search the project in the "projects" tab. But, it seems to be down for the moment. Adrien.

@Stef. Thanks for the link to the book. This is something I had not come across previously. I had seen the Google Code Pharo site but I'm still a little overwhelmed by all the information that is out there in various places. It's taking me a while to get familiar with it all and where to look for stuff. I'll get there eventually :) --Thomas. -- View this message in context: http://forum.world.st/Changing-Fonts-in-Pharo-tp2267560p2267705.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

@Nico. Thanks, that was what I needed. System Fonts > Code Font. Already set to DejaVu Sans Mono... I just increased the size to 12pts. I'm never satisfied... how about the font colour and background colour? Is there a setting for these or a tweek I can make via some nifty Smaltalk code? --Thomas. -- View this message in context: http://forum.world.st/Changing-Fonts-in-Pharo-tp2267560p2267701.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Hi Thomas, just go to: World -> System -> Preferences -> System fonts, there you will be able to set your favourite fonts. Other option that I use when I share code with my students is: open a Workspace and execute: *Preferences setDemoFonts*. and choose the size you desire.

Changing Fonts in Pharo

by tgc05

I'm new to Pharo and am working through the PBE book. I would like to change the fonts (and their size) used in the OmniBrowser and generally throughout Pharo. In particular, the font in the text input panes. I'd like to be able to use DejaVu Sans Mono, if available. Failing that, the default font is OK, if it could just be larger. (or is there a zoom feature?) Can someone tell me how I can customize these settings? Thanks. -- View this message in context: http://forum.world.st/Changing-Fonts-in-Pharo-tp2267560p2267560.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Finding packages

by Bob Cowdery

Sorry if this is a bit of a basic question. Could someone enlighten me on how to install packages please. I want to be able to run command files under windows from within Pharo. It looks like I need OsProcess or maybe CommandShell. I assume these should be installable from Monticello. I don't see any search facility in the Monticello Browser and tried a few repositories but failed to find what I needed. What's the best way to find packages. Thanks Bob
