Measuring width string
by Aliaksei Syrel Nov. 7, 2015

Nov. 7, 2015

Hi I'm sending it here so that it doesn't get lost. There are multiple ways to measure string width. In the following examples performance will be tested measuring 10`000 times the width of the following string: *string := 'abcdefghijklmnopqrstuvwxyz 0123456789!@#$%^&*()_+'.* 1) The most straightforward way is to send #widthOfString: to the font. Time to run gives around 250ms. http://ws.stfx.eu/2Q5YA9DFTRDR Resulting value is rounded to integer and seems to be not absolutely correct and precise. 2) More complex way is to go deeper on the level of glyphs and manually summarise the width of each character in the string sending #getGlyphWidth: character to the font. Time to run gives around 750ms. http://ws.stfx.eu/ETBEW1EHAAZ8 Resulting value is float and looks like correct and precise value. 3) Even more complex is to use CairoFontMetricsProvider instead of font's methods. The same as in 2nd case we measure each character. Time to run around 350ms. http://ws.stfx.eu/7I89DMD0ZLM3 Resulting value is exactly the same as in the 2nd case. With almost equal performance to 1st it is nice alternative. 4) One more way is to let native cairo to calculate everything for us. Calls happen through nativeboost. Time to run around 120ms. http://ws.stfx.eu/HYD76OMIOM7L <http://ws.stfx.eu/HYD76OMIOM7L> As result it returns *CairoTextExtents* which allows to calculate width and height with one call. Cheers, Alex

How to declare a script variable to hold attribute value in jQuery seaside
by Jayalakshmi Lade Nov. 7, 2015

Nov. 7, 2015

Hi, I am new to jQuery in seaside and trying to convert the below jQuery script to seaside jQuery for activating tabs and to render the related data but on another tab click getting *val* as 'undefined'. *jQuery script:* $(document).ready(function(){ $('ul.tabs li').click(function(){ var tab_id = $(this).attr('data-tab'); $('ul.tabs li').removeClass('current'); $('.tab-content').removeClass('current'); $(this).addClass('current'); $("#"+tab_id).addClass('current'); }) }) *My Converted jQuery code in seaside:* html document addLoadScript: ((html jQuery: 'ul.tabs li') onClick: (html jQuery ajax callback: [ :val | self tabId: val ] value: (html jQuery this attributeAt: 'data-tab')), ((html jQuery: 'ul.tabs li') removeClass: 'current'), ((html jQuery: '.tab-content') removeClass: 'current'), (html jQuery this addClass: 'current'), ((html jQuery id: self tabId) addClass: 'current')). Please give me your valuable suggestions on this. Thank you and looking forward for your reply. *Regards,* *Jaya L*

garbage on transcript
by stepharo Nov. 6, 2015

Nov. 6, 2015

Hi when I define methods and the Transcript is open I get such kind of trace and I do not get where it comes from. I think that this is the syntactical coloring. Would be good to avoid because this is annoying. StoreImporter>>messageSelectorAndArgumentNames (statements is Undeclared) UndefinedObject>>noMethod (messageSelectorAndArgumentNames is Undeclared) Stef

What is switch universe in Bloc?
by Stephan Eggermont Nov. 6, 2015

Nov. 6, 2015

I took a look at the latest Brick, and did 'switch universe' before opening the Brick examples. Resizing the Pharo window resulted in a black screen. If I first create a Bloc world, resizing works. (Ubuntu 15.04) Stephan
