the fastest way to load external code
 
|
Hi,
I am looking for ways to make loading of code from an st file faster. To this end, I would like to find in-image mechanisms that are not mandatory for obtaining a functional image. For example, one place I look at is SystemAnnouncer uniqueInstance, and I know that I should have no Nautilus open and that I can disable Renraku and GTExample: ReRuleManager uniqueInstance unsubscribe. GTExampleOrganizer instance stopSystemAnnouncements. What else do you see around? Cheers, Doru -- www.tudorgirba.com www.feenk.com "Don't give to get. Just give." |

Strikes me that parsing, not compiling and either holding onto the source String or simply keeping a pointer into the source file makes sense. Compilation to methods can wait until installation. With that approach you need no notifications at all. HTH _,,,^..^,,,_ (phone) > > Cheers, > Doru > > > -- > www.tudorgirba.com > www.feenk.com > > "Don't give to get. Just give." > > > > > > > |

Another thing you can do (but be careful) is to close the changes file. Sources (and change operations) will then not be written to disk which saves a lot of I/O operations. I use this for some special imports. I’m not sure however, how well that will work in Pharo 5 (I’ve been doing this in Pharo 1.3).

Hi,
Interesting. How do I do that? Doru > On May 22, 2016, at 9:49 AM, Max Leske <[hidden email]> wrote: > > Another thing you can do (but be careful) is to close the changes file.
