Re: [Pharo-users] How to grab a debug on Syntax Error?

by Henrik Sperre Johansen

Depends on whether you have a SyntaxErrorNotification or a SemanticError. For SyntaxErrorNotifications, you can wrap in a handler block raising a debugger (and will see at which index in source the error is for). Handling automatically is very kludgey without changes to the way OpalCompiler fetches source, which isn't really easily available to edit and resume from SyntaxErrorNotification handling code outside the scope of a controlling SourceEditor. For SemanticErrors, you're currently SOL, as they have a handling block in the compiler, rather than being raised and, only if unhandled, use a default action which notifies/logs dependent on whether compilation is interactive or not. -- View this message in context: http://forum.world.st/How-to-grab-a-debug-on-Syntax-Error-tp4950809p4950951… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Pharo6 server deployment and no home directory

by Juraj Kubelka

Hi Holger, I have an impression that it can be solved by using "--no-default-preferencesâ option: ./pharo Pharo.image --no-default-preferences Is it a good solution for you? Or do you need to load some preferences? Another option could be implementing an error signal, e.g., CantFindOriginError in the cantFindOriginError method and catch this in the GlobalIdentifier object.

Iâm not sure what to do in the Pharo environment, thought. Playground saves your scripts in pharo-local/play-cache folder. Use Tools->File Browser to look in play-cache/ or pharo-local/play-cache/ folder. You will find all your playground scripts saved in *.ph files. Note down this name (or rename it to something easy to remember) and make a copy. Pass this file as an argument: $ ./pharo Pharo myscript.st BTW, Playground is just that and a file is for unstructured stream of bytes. You may want to start using System Browser to create classes and methods, tests etc. for code worth preserving. Pharo offers you a lot of services like live debug, cross-refs, tracking changes, packaging etc. It is a lot easier than you think ;-). HTH .. Subbu

If you have a playground script maybe just having it as a .st file and running it with Pharo is good enough. Like pharo Pharo60.image myscript.st Check https://github.com/guillep/Scale Or get into Iceberg (Git) or Monticello to save your code as a package. Check deep into pharo, there is a chapter on these things. Gofer may also be a solution. Are you on Discord? Phil Le 12 juin 2017 01:22, "Glenn Hoetker" <ghoetker(a)me.com> a Ã©crit : > Hi all.

Help in thinking about how to save a "program"

by Glenn Hoetker

Hi all. Iâm new to Pharo and loving it. As I transition from a text-file based mindset, Iâm a little stuck and would appreciate help in how to think about a situation in a Pharonic (Pharo-ish, Pharoc?) way. Iâm crafting a short program to help me process a large text file (specifically: extract, sorting, and regularizing the âkeywordâ fields of a large BibTex file). Especially since I donât really know what Iâm doing, working in a Playground has been a great development environment. Now that the program is complete (under 30 lines, wonderful), I want to be able to save it for future reference (and perhaps for future use). If Iâd written a shell script, Iâd just save âfixBibDeskKeyWords.shâ to a directory. Iâm not sure what to do in the Pharo environment, thought. At the moment, it just lives in the Playground Iâve developed it on. I could save the image and leave that Playground open, but Iâm just positive thatâs not a best practice. I also worry about what happens if I closed/cleared that Playground by accident. I think I understand that, if I created a new package, I could use Monticello to save it to a local cache and load it into a new image whenever I needed it. But, given that itâs short, highly specialized and fairly linear, the idea of creating a âGHBibDeskStuffâ package with one class (âGBibDeskKeywordFixerâ containing a single âFixFileâ method seems really heavy and awkward. Can one save the contents of a Playground in a Pharonic way? Is there a better approach? Thank you to all involved in this wonderful programming ecosystem. I appreciate any advice.
