Embedded Pike revisited
by Stephen R. van den Berg 23 May '14

23 May '14

I've been doing some PCB work lately, exploring various MCUs, discovered that ARM MCUs are quite affordable these days. How feasible would a embedded-Pike be, kind of in the same spirit as this MicroPython: https://www.kickstarter.com/projects/214379695/micro-python-python-for-micr… -- Stephen.

Three patches for review
by Chris Angelico 23 May '14

23 May '14

I've posted each of these patches previously, but haven't heard a certain word as to their acceptance or rejection. Can someone please consider them? 1) Add a nodelay() function to Stdio.Files. There was some discussion as to whether or not this should be done in a more general way, but the discussion flagged and no conclusion was reached. 2) Represent a GTK G_TYPE_POINTER argument as an integer, rather than as an object. Every example I can find of a G_TYPE_POINTER coming back results in a segfault of Pike, which suggests that it's really not an object. I haven't found any instances where it really is meant to be an object, but that doesn't mean there aren't any. Does anyone know for sure? In any case, returning integers is safe for cases like the Notebook switch-page signal. 3) Ensure that something, at least, is pushed for every argument to a GTK signal callback function. Currently, unrecognized types can be simply skipped, resulting in stack mangling. My patch pushes the name of the type, thus preventing segfaults. The two GTK patches apply cleanly to 7.8 as well as 8.0, and can be considered bugfixes. The nodelay() function is definitely a feature addition, and is also not as important. Would love to see the GTK fixes arrive in time to go into the next published builds. Thanks! ChrisA

wix help
by H. William Welliver III 20 May '14

20 May '14

I’m working on preparing a build of 7.8.856 for Windows, and I’m having a minor problem with the resulting installer. Specifically, none of the dlls used in the modules are included in the generated msi. Does anyone know if there’s something particular I need to do to get the install generator to include them? In every other way, the msi looks good. Bill

Escapes
by Martin Nilsson (Opera Mini - AFK!) ＠ Pike (-) developers forum 09 May '14

09 May '14

So "\u1234" creates a string with one character '\u1234' in it. "\uu1234" however creates the string "\\u1234" with 6 characters in it. The "\uu" sequence gets turned into "\\u". This is intentional, as the code in the lexer says /* A double-u quoted escape. Convert the "\u" or "\U" to "\", * thereby shaving off a "u" or "U" from the escape * sequence. */ Where does this weird syntax come from? Why is it desired?

Concurrency in Pike
by Danesh Daroui 04 May '14

04 May '14

Dear Pike users and developers, I wanted to ask whether there is any library implemented for Pike to support concurrency or if it planed to do so as an embedded feature or added package? I think the language has a great potential to be widely used if such enhancements are done. I am reading the book "Pike: an Introduction" and have not seen any concept about concurrency yet (I am not done with the book yet). Thanks, Danesh -- Using Opera's mail client: http://www.opera.com/mail/

new 7.8 stable feedback?
by Bill Welliver 28 Apr '14

28 Apr '14

Hello all, It's been a little over a week since I posted a new alpha version, 7.8.852. Does anyone have any further feedback that needs to be addressed before I announce it as a beta version on the primary list? If I don't hear anything in the next day or so, I'll move it to the beta folder and make an announcement. Thanks! Bill

Image.FreeType multi face support
by H. William Welliver III 26 Mar '14

26 Mar '14

I’ve attached a diff that adds a new feature to Image.FreeType. I’ve not committed this because some additional work will be required to properly integrate this feature with Image.Fonts. As it stands, the diff should not break compatibility, but it seems possible that proper support in Image.Fonts *might*. Background: Certain font types supported by FreeType can contain multiple faces (be they varying weights or altogether unrelated typefaces) within a single font file. Currently, Image.FreeType and Image.Fonts will simply load the first face in the font file. I’ve noticed that, at least on MacOS X, the first font isn’t always a good default; for example, sometimes it might be a Bold-Oblique variant or whatever. It’d be nice to be able to access the others. The diff makes 2 changes: first, it adds a new field, “face_count”, to the results of Font->info(). The second change is the addition of a second, optional parameter to Font->create(), which allows the face number within the font to be specified. As I mentioned, it’d be nice to include support for this within Image.Fonts, though I’m not sure the best way to handle that. Any suggestions to that end would be welcome. As always, comments and suggestions are welcome. If there are no objections after a time, I’ll commit this change to 8.0. Bill
