Hum, use this instead: Usage: "Saving" self persistAsSton: someDataStructure toFile: 'persist.dat' "Loading" someDataStructure := self loadStonFromFile: 'persist:dat' Well, depends if you want to write to same file, different file etc, but this will get you on the right track On Wed, Nov 2, 2016 at 5:20 PM, phil(a)highoctane.be <phil(a)highoctane.be> wrote: > Use these methods in your class. > > loadStonFromFile: aDataFilenameString > > | data | > data := STON fromStream: ((self dataFileNamed: aFilenameString) > readStream). > ^data > persistAsSton: anObject toFile: aDataFilenameString (self > newDataFileNamed: aFilenameString) writeStreamDo: [ :out | out << (STON > toString: anObject) ] > > > dataFileNamed: filename > > "For an existing file" > ^ (FileLocator imageDirectory / 'data' / filename) fullPath asFileReference > > > newDataFileNamed: filename > | file | > file := (FileLocator imageDirectory / 'data' / filename ) fullPath > asFileReference. > file writeStream close. > ^ file > > > Usage: > > "Saving" > self persistAsSton: someDataStructure toFile: self newDataFileNamed: > 'persist.dat' > > "Loading" > someDataStructure := self loadStonFromFile: self dataFileNamed: > 'persist:dat' > > HTH > > Phil > > > > > > > > > On Wed, Nov 2, 2016 at 3:38 PM, Sven Van Caekenberghe <sven(a)stfx.eu> > wrote: > >> >> > On 2 Nov 2016, at 15:29, sergio ruiz <sergio.rrd(a)gmail.com> wrote: >> > >> > Hmmâ¦ i need to look at this .. >> > >> > i can just burp out all my objects with ston and suck them back in on >> the local machine.. >> >> Just try it ;-) >> >> STON put: myObjects onStream[Pretty]: fileStream. >> >> STON fromStream: fileStream. >> >> https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBo >> ok/lastSuccessfulBuild/artifact/book-result/STON/STON.html >> >> STON has already seen quite some usage, so you should be good. >> >> > On November 2, 2016 at 10:25:51 AM, phil(a)highoctane.be ( >> phil(a)highoctane.be) wrote: >> > >> >> Keeping data in image with a STON export would be good enough: >> > ---- >> > peace, >> > sergio >> > photographer, journalist, visionary >> > >> > Public Key: http://bit.ly/29z9fG0 >> > #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV >> > http://www.Village-Buzz.com >> > http://www.ThoseOptimizeGuys.com >> > http://www.coffee-black.com >> > http://www.painlessfrugality.com >> > http://www.twitter.com/sergio_101 >> > http://www.facebook.com/sergio101 >> >> >> >> >

Use these methods in your class. loadStonFromFile: aDataFilenameString | data | data := STON fromStream: ((self dataFileNamed: aFilenameString) readStream). ^data persistAsSton: anObject toFile: aDataFilenameString (self newDataFileNamed: aFilenameString) writeStreamDo: [ :out | out << (STON toString: anObject) ] dataFileNamed: filename "For an existing file" ^ (FileLocator imageDirectory / 'data' / filename) fullPath asFileReference newDataFileNamed: filename | file | file := (FileLocator imageDirectory / 'data' / filename ) fullPath asFileReference. file writeStream close. ^ file Usage: "Saving" self persistAsSton: someDataStructure toFile: self newDataFileNamed: 'persist.dat' "Loading" someDataStructure := self loadStonFromFile: self dataFileNamed: 'persist:dat' HTH Phil On Wed, Nov 2, 2016 at 3:38 PM, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > > > On 2 Nov 2016, at 15:29, sergio ruiz <sergio.rrd(a)gmail.com> wrote: > > > > Hmmâ¦ i need to look at this .. > > > > i can just burp out all my objects with ston and suck them back in on > the local machine.. > > Just try it ;-) > > STON put: myObjects onStream[Pretty]: fileStream. > > STON fromStream: fileStream. > > https://ci.inria.fr/pharo-contribution/job/EnterprisePharoBook/ > lastSuccessfulBuild/artifact/book-result/STON/STON.html > > STON has already seen quite some usage, so you should be good. > > > On November 2, 2016 at 10:25:51 AM, phil(a)highoctane.be ( > phil(a)highoctane.be) wrote: > > > >> Keeping data in image with a STON export would be good enough: > > ---- > > peace, > > sergio > > photographer, journalist, visionary > > > > Public Key: http://bit.ly/29z9fG0 > > #BitMessage BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV > > http://www.Village-Buzz.com > > http://www.ThoseOptimizeGuys.com > > http://www.coffee-black.com > > http://www.painlessfrugality.com > > http://www.twitter.com/sergio_101 > > http://www.facebook.com/sergio101 > > > >

Fuel is another option , though ston will be more readable because ston is text fluel is binary . SQLite is another one . You actually have a ton of options here. You can even make your own binary or text format if want , it's easy.

For this project, I want to make progress based on feedback from users ... there are lots of different directions that could be taken from this starting point and I want to be driven by user feedback ... so if you are willing to provide feedback I am willing to work with you ... i think that for my current project, I want to move REALLY quickly. so it might not be a good fit, but i would totally like to play around with it under different use cases. ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

Re: [Pharo-users] No, the installation of Pharo is not large its actually small

by Dimitris Chloupis

" ah, but this is fake (we have a bug shrinking the image). real image is around 32m. sources are also 32m. changes are going to be zero on release. " You mean a bug increasing the image size, because otherwise I dont understand you " how you get 43m in vm? my VMs (all of them, linux, win and mac), are never bigger than 12m cheers! Esteban " aha you are correct , in the vm folder contains the pharoV5.sources. This is very nice, 12 mb VM indeed, so there is a lot more room to compress than I initially thought. "Dimitris Add some node project size with npm dependencies for some nice sizes too. There it is also in terms of the number of files..." from what I am reading online, npm projects tend to be around 100 mbs, but still they give you no GUIs and no IDE. so maybe its 100 mb NPM + 200 MB the browser (Chrome / Firefox) + 100 MB the IDE plus some extra tools. But I am not NodeJS developer so I cannot confirm this. I have experience with all the languages I mentioned but I try to avoid the mess that is called "web development". By the way , those numbers are not much diiferent from Pharo. All the example I have that are 4-100x times bigger than Pharo offer also the equivalent libraries set , tools etc. For example Java and Python libraries are far larger than Pharo's. Most likely NPM is in that category. The lesson from this story is If you want a powerful environment expect to pay in hundreds of megabytes. If don't care then you can go down to few hundreds kbs . However judging from what is popular I think its safe to assume that developers love large powerful environments and don't care about size. Pharo if we take into account the size of its library , IDEs , tools etc 100 MBs is pretty much a very reasonable size. Now if we want to deliver a Lua-like Pharo version, with almost no VM, no library, no guis, no IDE just for the purpose of embedding it as a scripting engine, I am all for it. I cannot say I need it, but why not. But lets stop calling Pharo , fat, its not true and its rude. Pharo has feelings too you know :D

Dimitris, Add some node project size with npm dependencies for some nice sizes too. There it is also in terms of the number of files...
