Also, it was a totally fresh image downloaded from the site. on which system are you? Do you use a one click image if you use a normal single image not one click, when you download a package it is saved in the folder call package cache that is created on the side of your image. throw it away. Normally the file on the server are not corrupted. We test them before announcing a new release.

there is a directory package-cache in the same level that the image lives. are you doing this in the 1-click image or a normal image? assuming you can easily see the directory you can just delete it. I'm sorry i'm not more specific about the error. I'm hoping someone else chips in with a better description. Last time I debugged one I found it was an error in the zip protocol; i have no idea why. cheers, Mike 2010/4/19 Sean P.

Likely run for hours... oh yes I know the syndrome. Last time took me 5-6 hours for recompiling everything or what is just gtk :) What we will do is that I would like that this knowledge/burden is shared so we will give a try with jean-baptiste and cyrille to regenerate a plugin and compile it....

Hi, I think this is a common error caused by corrupt mcz files. Can you clear your cache and try again? thanks, Mike On Mon, Apr 19, 2010 at 6:47 PM, Sean P.

Re: [Pharo-project] Fonts for dummies

Read it as "if you meant kerning in the sense that the width of a string ~= width of each individual character" i.e., the ascent/descentKerns in StrikeFonts are not used for this. > What I am trying to discover is how to get the exact pixel size of '0xFFFF' and of 'suffix AV' - the latter will potentially involve more kerning than the former. When rendered by StrikeFonts, no, they will not, since it does not do kerning. For FreeTypeFonts, #widthOfString:from:to: does exactly what you ask. It wouldn't be impossible to add kerning to StrikeFonts, but it's a fairly major task as you'd need to: - Update the StrikeFont class to include kerningInfo, and implement kerningLeft:right: method - Define font construction methods etc. - Actually define useful kerning values for fonts in use. - Update the displayString: primitive to take into account kerning info Basically, the support is just not there at all at the moment for StrikeFont kerning.

[Pharo-project] Thrift servers in Pharo (help needed)

by Yoandy RodrÃguez MartÃnez

Hello everyone: As you may have noticed, Thrift doesn't generate Smalltalk server code. I've added some of the missing classes for server support (ported from python implementation) but my Smalltalk skills are not good enough to add server-side code into the generator. Is anyone interested?

(Try changing it to something other than 96 while using a FreeType font somewhere, and you can see the text size changing) Ideally there'd be code which gathers this value from the system at image startup, I'm not aware if such code exists though.

The fact that the Canvas is not involved is deeply discouraging: one should not have to edit a class method in order to involve a higher-resolution output device :( Please note, the "output device" in your definition, and a "Canvas" as defined in Squeak/Pharo, are two different things. A canvas does not know the physical dimensions of the display device its raster will be displayed on. Thus using it when rendering will not make any difference, but the TextStyles>>pixelsPerInch setting does what you'd like (for FreeType fonts). Repeated for clarity: > In essence, if those features are important to you: > - Use FreeTypeFonts. > - Set TextStyle pixelsPerInch: to a computed value at startup. The computed value here meaning: "Whatever you somehow manage to find out is the correct physical proportion". Cheers, Henry
