Find after in strings?

by Tim Mackinnon

Maybe this is a dumb question - and often Iâm surprised when asking these, but why is there no way to âfind afterâ a string. I find it rather boring to try and parse a string, after a known marker - thus: (loc := aString findString: âmarkerâ) > 0 ifTrue: [ loc := loc + âmarkerâ size ]. Is there a better way? This whole pattern seems very old and clunky and not smalltalk like? Couldnât we have: findAfter: aString ifAbsent: aBlock ? Or is there a whole better pattern for string searching that Iâm missing ?

Finder blows me away again

by Ben Coman

Just sharing... I wondered if there was a better way of converting an array of strings into one string than doing this... x := #( '++' '||' '++') . x flatCollect: [ :c | c ] but it was awkward copying the array twice into Finder. So I wondered if it could do variable assignment, and it can!! i.e... Tools > Finder > Examples > then simply paste the above snippet into the textfield. cheers -ben

In GsDevKit_home, use $GS_HOME/bin/todeBackup and $GS_HOME/bin/todeRestore to do a backup and restore ... these are bash scripts that call the tODE commands `bu backup` and `bu restore`, you will see docs for these commands when do the `man bu` ... if you are doing regular production backups (which you should be) you could simply restore from backup into your sandbox stone, whenever you want to start with a fresh extent ... While we are at it, take a look at the bash script $GS_HOME/bin/todeIt that allows you to call tode commands from bash ... a convenient way for you to do your deployment scripts, where you can write your own tODE command line scripts and then call them from bash ... With GemStone 3.5.0 (not yet released), it will be practical to write topaz/smalltalk/stash[1] bash command line scripts for deployment ... I plan to give a talk on stash[1] at ESUG this year:) Dale [1] https://github.com/dalehenrich/stash

This sounds okay ... I'd be inclined to have you also include a sandbox or QA stone in your setup, that is either a copy of the production db, or a db filled with test data, that you would use to validate your update process/code before each release to production ... better safe debugging in a sandbox, than sorry debugging in a production db:) > > Does this sound reasonable? > > Also, one thing that I find invaluable in troubleshooting applications > written using relational databases is to be able to be able to just > dump the production database and load it up on my local machine. Is > this possible using gemstones? Good you are thinking along the same lines ... You can take a snapshot of an extent in a running stone using the tODE command `bu snapshot` (run `man bu` in a tODE shell ) for more details, then using the GsDevKit_home bash script, $GS_HOME/bin/newExtent ( `$GS_HOME/bin/newExtent -h` for more details) you can install the snapshot from production into a local sandbox stone ... For future questions about GsDevKit_home and GemSTone, please the GLASS mailing list[1][2]. There are a number of folks in the wild that are using the develop in Pharo, deploy in GemStone model so you'll benefit from having those folks weigh in with their approaches as well, without cluttering the Pharo newsgroup with GemStone information. Also there are few more GemTalk employees that monitor the GLASS list and can weigh in with their knowledge as well :) Dale [1] http://forum.world.st/GLASS-f1460844.html [2] https://lists.gemtalksystems.com/mailman/listinfo/glass > > Thanks! > > > > ---- > peace, > sergio > photographer, journalist, visionary > > Public Key: http://bit.ly/29z9fG0 > #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV > http://www.codeandmusic.com > http://www.twitter.com/sergio_101 > http://www.facebook.com/sergio101

[gemstones] Use case for GsDevKit_home

by sergio ruiz

I have another project coming up, and I have free reign over the tech stack. I am gonna use Pharo, but I'd like to spend my up front time on this project figuring out the things I usually wait until the end to do. One of these issues is setting up gemstones. I would like to use GsDevKit_home, but I want to make sure that the use case I am envisioning is in keeping what this package is set up to do. My vision is something like: - Deploy a stone to remote production server. - Develop in the latest version of Pharo on my local machine, keeping my project in git. - When it's time to deploy, use tODE client to tell the production server to grab the latest code, and we're done. Does this sound reasonable? Also, one thing that I find invaluable in troubleshooting applications written using relational databases is to be able to be able to just dump the production database and load it up on my local machine. Is this possible using gemstones?
