Re: [Alphacocoa-devel] Alpha files

[Bernard D. <bde...@or...>]

Hi Joachim,

I think both actions you are trying won’t help you to achieve what you want:
- ‘Record Window State’ just records, as you can see, the following parameters: break-in and wrapping setting, encoding, font, tab size, selection (or current position) and page geometry. 
- the Alpha creator is a legacy but I’m pretty sure that the Finder ignores it completely.

I think the solution, to make Alpha the default application to open text files, is to select a text file (any text file) in the Finder, press cmd-I to open the Finder’s information window, then open the 'Open with’ section and select Alpha in the popup menu, then click on Modify All.


I’m glad you are satisfied with Alpha 9.1.3. BTW, I have great news concerning the next version Alpha 9.1.4: Alpha now has its own PDF viewers so that any PDF file (in particular those produced for instance by pdflatex) can be opened/visualized directly in Alpha AND there is synchronisation between the latex file and the pdf viewer. It works in both directions : from tex to pdf and from pdf to tex ! Just option-click somewhere in the pdf view and Alpha takes you to the corresponding location in the latex source. All within Alpha ! Alpha 9.1.4 has new PDFView and ThumbnailView views (to be used with the [view] command) with nice editing capacities (selection, scrolling, goto, etc.) and a new core command called [synctex] to manage the synchronisation. I’ll release a preview devbuild shortly so that everyone can test these new features (but at the moment I’m on vacation in the countryside with a very poor internet connection).

Cheers,
Bernard
