Please don't kill the in-place find feature of the former CTRL-J
by Masato Sumi 23 Dec '15

23 Dec '15

I'm very worry about that the new CTRL-J (aka "again") of tunk seems lacking very old but elegant feature of the former CTRL-J, "in-place find" function. When you just inserted text at a caret, the former version of CTRL-J (or select "again" from yellow-button menu) sets the text as a search key then delete it and then select next found text. I prefer and everyday use this feature because it make me find the text very seamlessly. I know my English is too bad to explain about this feature, so I made a screen-recording below. (Although it is very old Apple Smalltalk, you can do the same thing in current Squeak but not trunk) https://www.youtube.com/watch?v=-jKdn_9dKeQ If it was my misunderstanding and the new CTRL-J still keeps this feature, please let me how to use it. Thanks -- sumim

Changes to Trunk (http://source.squeak.org/trunk.html) in the last 24 hours: http://lists.squeakfoundation.org/pipermail/packages/2015-December/009218.h… Name: Morphic-mt.1061 Ancestors: Morphic-tpr.1060 Text editing: code clean-up and fix for in-place find. Here is how it works: - You just moved your cursor to some place without selecting something. - You type something. - You hit CMD+G to "find again" - The previous input will be removed and taken as search text. - The next match will be selected. - (If you err here, you can undo with CMD+Z to insert the input from above again.) If you hit CMD+J, nothing will happen because there was no replace operation detected. If you, however, hit CMD+G to find the next match and then continue wit a CMD+J, it will find/replace the next match (with nothing) because your insertion was removed automatically as described above. ============================================= http://lists.squeakfoundation.org/pipermail/packages/2015-December/009219.h… Name: ToolBuilder-Morphic-cmm.154 Ancestors: ToolBuilder-Morphic-mt.153 Encountered the model already nil'd out before entering PluggableSystemWindow>>#delete on occasion.

ftp change: /trunk
by Tobias Pape 22 Dec '15

22 Dec '15

Dear all I just noticed, that http://ftp.squeak.org/trunk actually was a deep copy of http://ftp.squeak.org/4.2alpha. I removed the content from /trunk and made it a link to http://ftp.squeak.org/5.1alpha. Best regards -Tobias PS: the usage of FTP to access the files is actually steadily decreasing. What about renaming it to files.squeak.org, keeping content? [and, important for box admins, moving it away from the box2-on-box4 infra]. Thoughs?

review, validation and test development for GenericGF
by Robert Withers 22 Dec '15

22 Dec '15

Hi all, sticking with the distribution for discussing Crypto in the base, I am currently trying to stabilize a port of Reed-Solomon such that FEC can be added to SecureSession. I am doing this work in SecureSession. I just posted an update of the GenericGF class, with the Java implementation attached here. I need this critical code reviewed and tested. You need Cryptography and SecureSession to be included in the catalog. If you can help me with the former, I could help with the latter, if that suits you. Please let me know! Please load Cryptography(-Pharo) and SecureSession.23 for review. "ported & refactored GenericGF from the java code. This includes reindexing from 0 to 1. Having no tests, hopefully someone can give a review of this specific class. Where some tests to be developed at this scope, that would be stellar." I appreciate. -- . .. .. ^,^ best, robert

Re: [Pharo-users] [squeak-dev] encoding challenge
by Robert Withers 21 Dec '15

Thank you, this is good. I was modeling DateAndTime as UTCTime, which is a specified format for two digit years: http://www.obj-sys.com/asn1tutorial/node15.html. I noticed this other time representation while lookin... GeneralizedTime: http://www.obj-sys.com/asn1tutorial/node14.html. To meet that format with padding, I decided to convert to strings. Not pretty but there is a test! :) Unfortunately the ASN.1 DER endoding for time is specific format. I coudl just throws milliseconds in an integer slot, but I wanted to meet the spec as well for a full ASN.1 tool. I am undecided whether to use ASN.1 for header encoding in SecureSession, or custom binary specification - I use the second option at this time. Yet I am in the middle of redefining that message protocol, so now would be the time to decide. Fuel and I have a date coming up, for sure. thank you, Robert On 12/21/2015 03:34 PM, Sven Van Caekenberghe wrote: > Robert, > >> On 19 Dec 2015, at 07:09, Robert Withers <robert.w.withers(a)gmail.com> wrote: >> >> A core part of communications, whether online or to persistence, is encoding, or marshalling.

From your code I assume you are only interested in second precision and the UTC/GMT/Z timezone.

When mistakes like this happen, I think its better to revert to the ancestor and try again, rather than embalm these kinds of meta-notes forever into the history. 'copy image versions here' does exactly what its meant to and what it says it does.
