font installer & free type fonts
 
|
Hi,
To ease the transition to Athens, we need to get free type fonts in the image. I researched a bit, and found a couple of font families that are nicely free and open-source: DejaVu, Source Code Pro, Source Sans Pro, and LinLibertine. I put together a little tool that imports a TTF file and installs it in a dedicated class. You can find a library of already imported fonts on SmalltalkHub: http://www.smalltalkhub.com/#!/~girba/FreeFonts/ More details about this library can be found at: http://www.tudorgirba.com/blog/free-font-collection-for-pharo For example, you can use the SourceCodeProRegular font as a code font like: Gofer new smalltalkhubUser: 'girba' project: 'FreeFonts'; package: 'SourceCodeProRegular'; load. (Smalltalk at: #SourceCodeProRegular) new install. FreeTypeSystemSettings loadFt2Library: true. StandardFonts codeFont: (LogicalFont familyName: 'Source Code Pro' pointSize: 10). The Moose image already comes with a convenience method to set a complete free type font set: MooseImageSetupCommandLineHandler new installFonts.

Hi doru
How do you use SourceCodeProSemibold for example StandardFonts codeFont: (LogicalFont Because there is no family name for semi bold Stef On May 11, 2013, at 12:21 AM, Tudor Girba <[hidden email]> wrote: Hi, _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

Hi,
The fonts-related code is a bit too complex for my mind. Semi bold is indeed not a FreeTypeFontFamily, but a FreeTypeFontFamilyMember. After loading the font, you can inspect it via: (LogicalFontManager current allFamilies detect: [:each | each familyName = 'Source Code Pro' ]) members detect: [ :each | each styleName = 'Semibold' ]. You will see that it has a couple of integer values for: stretch, weight and slant. The only way I could set a LogicalFont from outside was via these values explicitly: StandardFonts codeFont: (LogicalFont familyName: 'Source Code Pro' pointSize: 10 stretchValue: 5 weightValue: 600 slantValue: 0). I guess we need to review this part of Pharo.

Hi , Doru
i have only one question: why you put font binary data into compiled method? That means that in object memory it will be contained 3 times: - 1 as source code - 2 as big literal array - 3 in freetype memory buffer imo, #fontContents should be fontContents ^ self url getContents ".. or whatever.. url is key here" ... or you can download the binaray data and put it into class var (lazy-initialized etc).. but do not hold binary data as source code.. this is really awful idea as to me. unless you worry that longevity of your file copy @ smalltalk-hub will be higher than longevity on site where you downloaded it from. -- Best regards, Igor Stasenko. _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

Since package is also downloaded from internet, there's no worry that font will be unavailable during installation (unless the site where it located changes file location). Like that, the package will contain just minimum necessary bits to install the font. And also, having url available, makes it easier for users to add own fonts by simply overriding it, without need of figuring out how to turn a binary file into method's source code. > -- > Best regards, > Igor Stasenko. -- Best regards, Igor Stasenko. _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

Do you care? Because I like the idea to have self contained package. We can do the inverse: remove the method once the fonts are installed? I do not want to rely on a web connection to get the system working. > Since package is also downloaded from internet, there's no worry that > font will be unavailable > during installation (unless the site where it located changes file location). > Like that, the package will contain just minimum necessary bits to > install the font. > And also, having url available, makes it easier for users to add own > fonts by simply overriding it, > without need of figuring out how to turn a binary file into method's > source code.

Hi, The reason I took this path was because this is how we are dealing with pictures as well. Furthermore, the fonts are downloaded from sourceforge and that is neither the fastest nor the most reliable site. As Stef said, if we are worried about the size, we can easily unload the package after installing. So, for me, the current solution is simple and as reliable as any other Pharo code. In other words, if SmalltalkHub fails, many other things will fail before the fonts become an issue.
Nevertheless, it could be interesting to create an index class that can build fonts on the fly based on a url. For this, we would need a repository somewhere reliable :).
About the easiness of compiling the binary file, there already exists a utility documented on my blog post: Gofer new smalltalkhubUser: 'girba' project: 'FreeFonts';
package: 'FontInstaller'; load. fontDirectory := FileSystem workingDirectory / 'Fonts' / 'SourceCodePro_FontsOnly-1.017'.
FontInstaller new installFromDirectory: fontDirectory / 'TTF'
license: ((fontDirectory / 'LICENSE.txt') readStreamDo: #contents). Cheers, Doru On Wed, May 15, 2013 at 9:42 AM, stephane ducasse <[hidden email]> wrote:
