[squeak-dev] Prevent syntax errors in preamble/postscript

Interesting idea. We could simply change the underlying representation of PackageInfo ('preamble postscript preambleOfRemoval postscriptOfRemoval') to hold CompiledMethods rather than StringHolders and rewrite the accessors to use Compiler and #sourceText. However, then we could not use interactive compilation (no requestor). Hm, or could we maybe simply store instances of CodeHolder? This could also solve our problem that Monticello Load Scripts are not styled<http://forum.world.st/Monticello-Load-Scripts-are-not-styled-td5109840.html>.

Speaking in general, should we maybe revise the existing StringHolder, CodeHolder, MethodHolder hierarchy? A very large part of the StringHolder implementation actually describes code-specific things. MethodHolder, on the other hand, is located in Tools but its only three users are located in EToys. IMHO, an ideal StringHolder would not contain any code-related stuff, not even #buildCodePaneWith:. Or am I basically describing the behavior of a ValueHolder? In this case, the name of StringHolder is quite confusing.

Thank you Nicolas for fixing this error so quickly.

Would it be possible to compile, but not evaluate those scripts automatically when they are saved? Or does something speak against it? It should prevent syntax errors.

Kind regards,
