about expressions

by Stephane Ducasse

I do not get why (Yes I know it is because it is not in the syntax.... but it is conceptually not nice). | d | d := Dictionary new. d at: #top at: #below1 put: 1. d at: #top at: #below1 put: 2. d at: #top at: #below1. is not an expression in Pharo. It means that I can manipulate 1 + 3, x + 3 as an expression but not a sequence. So it forces me to use a block to convert artificially a sequence in an expression. [ | d | d := Dictionary new. d at: #top at: #below1 put: 1. d at: #top at: #below1 put: 2. d at: #top at: #below1. ] value So if I want to build a repl executing expression then this is not a Pharo repl but just a stupid expression. I would like to know what would be impact to have sequence and declaration as expression. Stef

Re: [Pharo-dev] FileReference>>/ and path canonicalisation

I did not take any blame in wht you say. I just wanted to explain that yes comments can be wrong :) I'm super happy to get some brains looking at improving FS. I'm fighting to see how we can start to integrate faster changes in P70.

The comments appear to align with the design goals of the class. And I really do agree with the goals, it is just that given the confusion it creates, in this particular case it is more practical to parse the strings. Actually issue 18042[1] offers an alternative approach, which is to enforce not allowing the directory delimiter. I would extend the error message to suggest using #resolve: instead. I think that following the programmer's rule of being strict in what you write and forgiving in what you read, parsing the string is more practical, but I'm keen to see what everyone else thinks.

Ok I try to understand. I already cloned the github repo and I do not want to be forced to download all these small files all the time. I want one place with all the forked code one and only one.

Feel free to ignore this section, it isn't important to the conclusion... But that's my point - it depends on where the image is launched. If I want to be sure that the file will be found, I need to resolve from the image directory, not the process current working directory.

Reviewing of the pull requests

by Pavel Krivanek

Hi, the reviewing of the pull requests is currently not as easy as we would like to have. For simple changes it should be enough to go to the pull requests list (https://github.com/pharo-project/pharo/pulls) and review the changes from the GitHub web interface. In case that the PR passes tests and bootstrapping, it should be fine. However if you want to play with an image that contains the PR code, your options are more complicated. The basic and the most clean one is to bootstrap from the repository with the PR applied on it. But it takes A LOT of time (over 20 mins). You can use this script that you will run inside the clone. set -e export PR=122 export BRANCH=development export PHARO_VERSION=60 export BOOTSTRAP_ARCH=32 git fetch origin $BRANCH git fetch origin refs/pull/$PR/head git checkout -b pullrequest FETCH_HEAD git merge --no-edit origin/$BRANCH #git diff origin/$BRANCH..pullrequest > pullrequest.diff wget -O - get.pharo.org/${PHARO_VERSION}+vm | bash ./pharo Pharo.image --no-default-preferences ./bootstrap/scripts/ prepare_image.st --save --quit ./pharo Pharo.image --no-default-preferences ./bootstrap/scripts/ bootstrap.st --ARCH=${BOOTSTRAP_ARCH} --quit bash ./bootstrap/scripts/build.sh The other option is to take existing Pharo 7 image, have pharo-project/pharo clone next to it in a folder named 'pharo-core' and then create a new branch with the merged pull request. Currently it cannot be done from Iceberg directly so you need to use Git. You can use this script: set -e PR=119 COMMIT=2225314a7404c9e00fe71e70d41fc59d4ba78e2d cd pharo-core git fetch origin refs/pull/$PR/head git checkout -b pr$PR-local FETCH_HEAD git checkout $COMMIT git checkout -b pr$PR-merged git merge --no-edit pr$PR-local #git diff $COMMIT...pr$PR-merged > pr$PR.diff Set the pull request name to the variable PR and the image commmit hash to the variable named COMMIT. It can be obtained by "SystemVersion current commitHash". As the result you are in a merged branch created for this pull requests (e.g. pr122-merged) and you need to reload all packages. It can be done from Iceberg where you will need to confirm several dialogs, or by this script: repo := MCFileTreeRepository new directory: './pharo-core/src' asFileReference; yourself. versions := OrderedCollection new. repo allFileNames do: [ :packageName | | wc | wc := MCWorkingCopy allManagers detect: [ :each | each packageName = (packageName withoutSuffix: '.package') ] ifNone: [nil]. wc ifNotNil: [ [(repo loadVersionFromFileNamed: packageName) load] on: MCMergeOrLoadWarning do: [:w | w resume ] ]] displayingProgress: [:e | e ]. The other option is to let display the classical Monticello merging window. For that you can use this script: repo := MCFileTreeRepository new directory: './pharo-core/src' asFileReference; yourself. versions := OrderedCollection new. repo allFileNames do: [ :packageName | | wc | wc := MCWorkingCopy allManagers detect: [ :each | each packageName = (packageName withoutSuffix: '.package') ] ifNone: [nil]. wc ifNotNil: [ versions add: (repo loadVersionFromFileNamed: packageName) ]] displayingProgress: [:e | e ]. merger := MCVersionMerger new. versions do: [:each | merger addVersion: each ]. merger mergeWithNameLike: 'merged'. merger gatherChanges. (merger instVarNamed: #records) do: [ :each | each mergePatch operations do: [:operation | operation chooseRemote.]]. (merger instVarNamed: #merger) operations do: #chooseRemote. merger resolveConflicts. However I have seen cases where for example the PR deleted some class and the MC merging tool was not able to see this change. So be careful with this approach. We need to look at that. Do not look on this mail as something final. It's only a hint for brave sprinters. To find a good workflow how properly review our PR should be one of our priorities. Cheers, -- Pavel

Re: [Pharo-dev] Pharo 7 provisional HOWTO

by Pavel Krivanek

Unfortunately you cannot share the repository the way you try because it always needs to be in the image working directory in a folder named 'pharo-core'. Without it the Monticello will not be able to see changes int the packages. On one location place Pharo 7 image and execute the first script that clones the repository and sets the remote fork. Then into some other repository take a fresh Pharo 7 image, create symlink to the 'pharo-core' folder in the original directory and then execute the second script that only registers this repository into Iceberg and sets proper pull and push targets on it.

If you're running from the command line, $ pharo Pharo.image eval " 'someFile' asFileReference fullName " will be a file relative to the path of the image, if you open the image from where it is located (ie, working directory = image directory). This is yes different when you're 1) deploying the image in one directory, but you're using it from another one $ someDir/pharo someOtherDir/Pharo.image eval " 'someFile' asFileReference fullName " But then, why working directory should be image directory and not VM directory?
