You want to start from a minimal image and load everything you need with a Metacello baseline/configuration. And you want to change some settings to run without sources.

Re: [Pharo-users] RB refactoring rewrite variable to a symbol

Hi Peter, i assume from your question "RewriteTool maintained?" that you want to make a RBTransformationRule, right? if yes, i once had a similar problem and overwrote only #checkMethod: checkMethod: aMethod Â Â Â | arg | Â Â Â arg := aMethod argumentNames first asString. Â Â Â self initialize. Â Â Â self rewriteRule Â Â Â Â Â Â replace: Â Â Â Â Â Â Â Â Â '| ``@temporaries1 | Â Â Â Â Â Â Â Â Â `.@Statement' Â Â Â Â Â Â with: Â Â Â Â Â Â Â Â Â ('| ``@temporaries1 | Â Â Â Â Â Â Â Â Â {1} blahblah ifTrue: [ ^ {1} adaptToNumber: self andSend: #{2}]. Â Â Â Â Â Â Â Â Â `.@Statement' Â Â Â Â Â Â Â Â Â Â Â Â format: {arg. aMethod selector}). Â Â Â ^ super checkMethod: aMethod not too elegant, but it works. you could strip ":" from the method selector and do something similar. werner On 11/11/2017 05:17 PM, Peter UhnÃ¡k wrote: > Hi, > > how can I rewrite a(n instance) variable to a symbol? > > E.g. > > [IN] > something: aSomething > Â Â something := aSomething > > [OUT] > something: aSomething > Â Â self write: aSomething into: #something > > > I can capute the input just fine... ``@var := ``@arg > but I have no idea how to convert the var into a symbol (or string). > > Thanks, > Peter >

deployment of pharo applications

by ÐÐ¸ÐºÐµÐ½ÑÐ¸Ð¹ ÐÐ¾ÑÐ°Ð¿Ð¾Ð²

Well, i've got very extensive feedback for i18n of applications, there are few solutions i can use, despite there is no united way embedded into pharo view on application design. That's ok, i can do something for my one taste (i prefer it to be a part of SPEC framework or something like this). Another stumbling block is application deployment. I've heard about some "Launcher" but ... what is it? what it does? where to get it? In Cincom VW deployment means: - get rid of all we don't use in image. - test image for successful run - delete all sources (hide it from disassembler) - lock\hide all excessive menus, tools or any backdoor to launch Smalltalk IDE or execute smaltalk code presented as text. - pack image and VM together with specified name of main executable. What can i do with Pharo? Does it have unified method to deploy pharo applications? I didn't find that method, and i ought to do some messy stuff "by hand". It will be very useful to do some steps in that direction. I want Pharo to be comfortable tool for application development. Like Delphi or C++ (where i came from but don't want to get get back to, after Smalltalk any other platform seems imperfect for me). Faithfully yours, Vikenti Potapov.

Re: [Pharo-users] RB refactoring rewrite variable to a symbol

by Thierry Goubier

Hi Peter, Hi Peter, you should try {:node :dic | ... } to handle that. Something like: RBParseTreeRewriter new replace: '`@var `{:node :dic | dic at: #varName put: node name} := `@arg' with: 'self write: `@arg into: `{:dic | RBParser parseExpression: ''#'', (dic at: #varName) }'. You need to adjust, I haven't checked if this is correct ;).

RB refactoring rewrite variable to a symbol

by Peter UhnÃ¡k

Hi, how can I rewrite a(n instance) variable to a symbol? E.g. [IN] something: aSomething something := aSomething [OUT] something: aSomething self write: aSomething into: #something I can capute the input just fine... ``@var := ``@arg but I have no idea how to convert the var into a symbol (or string). Thanks, Peter

Most of the web pages I want to scrape use javascript to construct the DOM, which makes Soup. XMLHTMLParser, etc. useless. I've extended Torsten's Pharo-Chrome library and use that to navigate the DOM in a way similar to Soup: https://github.com/akgrant43/Pharo-Chrome This gets around the issue with javascript since it waits for the browser to load the page, run the javascript and construct the DOM.
