[Pharo-project] Trying to understand DateAndTime
by Nicolas Cellier April 29, 2013

April 29, 2013

Since DateAndTime comment is out of date (sic !) and current implementation seems not free of bug, here is an effort to summarize and understand the whole thing, let's call this a review. Please tell me where my interpretations are wrong. 1) The DateAndTime is stored internally as - a point in UTC time (julianDayNumber, seconds, nanos) - an offset from UTC (a Duration) denoting the local time zone 2) The ticks method returns the UTC part {julianDayNumber. seconds. nanos} 3) DateAndTime print themselves in local time using the offset 4) other methods (with some exceptions) return the local dateAndTime parts (year month day hours minutes seconds) Exceptions are: - secondsSinceMidnight (which should be renamed secondsSinceMidnightUTC IMO, even if the method is classified private) - julianDayNumberUTC as the name tells So far so good (but secondsSinceMidnight which is error prone) What I find strange: - #hash uses the offset... Why ??? d1 := DateAndTime now. d2 := d1 offset: d1 offset + 1 hours. { d1 = d2. d1 hash = d2 hash. } gives #(true false), a clue? - #< compares julianDayNumber (the UTC inst. var.) with otherDate julianDayNumber (with otherDate local offset) which seems wrong, it should better use julianDayNumberUTC or (normalized) ticks. - #= could be simplified and accelerated if using #hasEqualTicks: (if the ticks are correctly normalized though which would be the case since #ticks:offset: does, unfortunately #setJdn:seconds:nanos:offset: does not). Some senders of #setJdn:seconds:nanos:offset: don't normalize the day/seconds/nanos, though it should be their responsibility (DateAndTime todayAtMilliSeconds: xxx) (DateAndTime todayAtNanoSeconds: xxx), not counting year:month:day:hour:minute:second:nanoSecond:offset: which does not either (many senders...). Maybe we should better let the normalization responsibility to #setJdn:seconds:nanos:offset:. It remain to analyze the conversion protocol (asYear etc...) which seems to use the local time year, but I don't understand the whole Timespan thing right now (why DateAndTime now asYear starts now, and not on january 1st?).

[Pharo-project] ssl fails on build CI
by Max Leske April 29, 2013

April 29, 2013

The FileSystem-Git builds on CI generate many test failures because the SSL plugin is missing (apparently) here's the output: https://ci.inria.fr/pharo-contribution/job/FileSystem-Git/6/PHARO=20,VERSIO…. Is that to be expected? I gathered from a recent thread that at least libssl should be present on the CI servers. Or do I need to change something in the configuration? Max

[Pharo-project] State of PharoConf videos
by Stephan Eggermont April 29, 2013

April 29, 2013

Hi, I'm very happy to see that the initiative to make video recordings of the PharoConf and MooseDay has resulted in so many screencasts already published. Great work! And now the first feedback: - Format conversion: 62 of 72 GB done, processing the whole weekend. - First 13 minute part currently encoding and uploading. Still about an hour and a half to go. - I would like to receive the presentation files to combine them with video. - Some of the material is difficult to use. Zoomed out too much it is difficult to follow the speaker and the beamer screen is not readable. Combining a screencast with the video only makes sense when zoomed in (talking head size). Why does this take so long? - the video is in a format that I cannot work with directly, so needs transcoding. I have been using VideoMonkey for this, which is based on ffmpeg. I have the impression that this ffmpeg is not using the GPU, but only the i5. I'm open for suggestions on better software for this in the future, as it takes the whole weekend. - I switched from iMovie to Final Cut Pro X. That allows non-linear editing, so I don't have to wait for rendering to cut the movies. It remains responsive even during the format conversion. - video is much larger than the equivalent length of screencast. That creates a upload bottleneck. 13 minutes of HD video is 733 MB. My home upload is 1Mbps (2 hours), so for uploading more material I'll ask someone at our local university. - I'm spending a limited amount of time during the weekend (and none next week). Stephan

[Pharo-project] [FYI] Athens tutorial
by Igor Stasenko April 29, 2013

April 29, 2013

Hello, there i prepared a small tutorial for Athens, which i did today at PharoConf. But the code i did can be reused by non-participants of conference :) Here the instructions. Download Pharo 2.0 wget -O - get.pharo.org | bash Run Pharo 2.0 ./pharo-ui Pharo.image In a workspace, evaluate (line after line) Gofer it smalltalkhubUser: 'Pharo' project: 'Athens'; configuration; load. ConfigurationOfAthens loadVersion: '2.0'. Gofer it smalltalkhubUser: 'Pharo' project: 'Athens'; package:'Athens-Tutorial'; load. AthensTutorial new openWithSpec. Took from here https://gist.github.com/SergeStinckwich/44ca34b54cde83b687a3 (just removed duplicates ;) Thanks, Serge for compiling it down ;) Once you load the code and have window open, skip step one (you already did it), and then just follow the steps by pressing doit button changing the code , pressing doit again , going forwards etc .. and playing with it. I put some comments there to serve as a small description/detail. Any feedback & help & contributions & improvements is welcome. P.S. if you get a DNU at step 30, enable Freetype in settings and try again. -- Best regards, Igor Stasenko.

[Pharo-project] [Ann] TxText. New text editor done!
by Denis Kudriashov April 28, 2013

April 28, 2013

Hi guys. I'm happy to announce that new text editor based on new text model done. You can load configuration from http://www.smalltalkhub.com/#!/~sig/TxText. Last version: 0.6. See class side example methods. What available now in TxTextMorph: - cursor navigation with move left, right, down, up and mouse click - text selection with move left, right, down, up and mouse movement - editing by keyboard input - text wrap - #addCursor/#removeCursor - #enableSelection. - #beEditable - all keyboard interractions based on shortcuts Little details about navigation and editing: There is TxEditor object which know about cursor position and text selection. Text morph ask him to perform all navigation and editing behaviour. It has cursorMode which knows how to change editor selection when cursor moved. Editor delegates all move actions to cursorPosition by #doesNotUnderstand method. It is simplified adding new navigation methods. For example see TxTextMorph>>enableSelection aTxTextMorph>>moveEditorOn: Character arrowLeft by: #moveLeft. This expression adds two shortcuts: to move editor left and to select text left (when selectionModeModifier active). What next: - Remains standart navigation and editing features like copy/paste, move to line end, to text end and etc. - halo menu items to edit text and layout properties - Edit decorators to get mask behaviour like "(999)***-**-**", pretty numbers like "1'000'000", secrete field like "***" - Value specs to filter inserted text (only numbers, only english and etc) There are some problems with focus behaviour now. And drawing text morph with transparent back color works bad. It will be cool if somebody with good knowledge at this topics can fix it. Best regards, Denis
