Re: [Pharo-users] YAML parser (2017)

by Peter Uhnak

Hi, Phil Back has kindly fixed the PetitYAML so it mostly works now. The only problem I've encountered was some weird misparsing of strings containing slashes, e.g. "5/". In any case: Install PetitParser (from Catalog or somewhere), load PetitYAML package (this is already loaded when loading PP from catalog). And then parse your string ``` PPYAMLGrammar parse: ' language: c sudo: false cache: directories: - opensmalltalk-vm/.thirdparty-cache git: depth: "5"'. ``` "Dictionary( 'cache'->a Dictionary( 'directories'->#('opensmalltalk-vm/.thirdparty-cache') ) 'git'->a Dictionary( 'depth'->'5' ) 'language'->'c' 'sudo'->'false' )" Take a look at PPYAMLGrammarTest>>testTravisYml too.

I ran into this problem with the wonderful (as it had a SHA256 implementation) NaCl bindings. Pharo5: * RBParser still has the currentScope variable and can import it * Syntax highlighting ends in an exception (which I disabled) Pharo6: * RBParser doesn't have currentScope anymore so I patched it out * Syntax highlighting seems to work fine @Esteban: Would you accept a change to the FFI-Pharo5Compat to not use the currentScope variable/reduce error checking? Or would you accept it in a FFI-Pharo6Compat package? I think it would help to be able to load the Nacl code in Pharo6 and then fix it? what do you think? holger

> On 24 Jul 2017, at 15:11, Hilaire <hilaire(a)drgeo.eu> wrote: > > Thanks guys. > > I hope it includes the fixes for the bugs impacting Dr. Geo. > Hello, I think there is a bit of a confusion of how we do fixed for Pharo6. I will explain: -> if people find bugs, they end up on the issue tracker -> Some of these get fixed. If a fix is ready, we will integrate it very quickly. This means that only the update number changes, not the main version number (these are bug fixes, they do not change APIs). A good name for these updates is âhot fixesâ. They are announced to the dev list only with the automatic lists that are send for each update. We integrated already quite some into Pharo6 like that. The release was I think around #60500, while 6.1 was done around #60510 Then there are cases that are more grave: 6.1 was done because it contains bigger changes. What I think would have been good is to list all the updates that where done between releasing 6.0 and 6.1 *as part of the changelog* of 6.1 (even though they were already in the image that you got a minute before Pharo6.1 was released, as they where released as hot fixes before). Now if the image includes all fixes needed for DrGeo depends on a) has that issue been fixed and b) if yes was all massaging done to have the update actually integrated. (what does not help is that it is holiday time, e.g. I did not read emails and did *nothing* from end of Juli to yesterday, this does not help but was really, really needed). Marcus

Now if this is so close to the truth that means two massively important things.
