Hi,

What is the story around PharoMinimal and related images ?

Is there a writeup somewhere with instructions ?

Right now the minimal (Metacello) image based on Pharo 7 is used only as intermediate step in building of the full Pharo and the only real (successful) attempt to use it for something else is PharoLambda (https://gitlab.com/macta/PharoLambda).

In general it can be used for building of own (server) applications. E.g. this way you can install and run Teapot on it:

./pharo Pharo7.0-metacello-32bit-d13eed2.image config http://smalltalkhub.com/mc/zeroflag/Teapot/main ConfigurationOfTeapot --install=stable

./pharo Pharo7.0-metacello-32bit-d13eed2.image eval --no-quit "Teapot on GET: '/welcome' -> 'Hello World'; start."

You can load baselines from the Git repositories too but we currently do not have any command line handler for it so you need to do it using "eval" command or *.st flile. Something like this:

Metacello new

baseline: 'Seaside3';

repository: 'github://SeasideSt/Seaside:master/repository';

load

To make it more usable we probably should extend it with SUnit and Fuel. If you want to extend it with some packages from vanilla Pharo, you should load them using FileTree from your local Pharo repository clone.

Gofer it

url: 'filetree:///path-to-my-pharo-repository-clone/pharo/src';

package: 'Multilingual-OtherLanguages';

package: 'Multilingual-TextConverterOtherLanguages';

load.

It still needs some care. E.g. some classes from Zinc are not properly initialized (I know about��DigitalSignatureAlgorithm MD5NonPrimitive RxMatcher RxParser RxsPredicate SHA1 ZnByteEncoder ZnConstants ZnMimeType ZnNetworkingUtils ZnServer ZnSingleThreadedServer TextConstants TextAction TextStyle).

I tried to load Seaside into it today (from the example above) and it failed (some strange error probalby related to Unicode processing). But we will fix it. If you will tell me what exactly you need we can make it work together as in case of PharoLambda.

I see that we get **FANTASTIC** startup speed with it:

That is less than 1/10 of a second on a simple server ! Wow.

Loading new code in that image seem hard though.

I see that in http://files.pharo.org/image/70/ there are Pharomonticello & Pharometacello variants.

Any pointers on usage/meaning ?

Monticello is bootstrapped Pharo image with Monticello loaded. This image then loads Metacello and the generated image is the image that we call "minimal". It is minimal in sense minimal for common usage.

During Pharo building process we generate:

- bootstrapped image

- image with Opal that is loaded as binary packages using Hermes

- Monticello with only local repositories support

- Monticello with network and remote repositories support

- Metacello

- full Pharo IDE (which is loaded as sequence of several standalone baselines)
