Can't unembed, or decend into embedded symbols

[Peter Clifton]

Looking at gschem/tests/agile-vfo-block_1.sch

I noticed some embedded components which don't have their whichone flag set. I thought I'd see how the user can fix this, but:

I can't get gschem to un-embed the component (where would it save the file? I don't believe the required symbol exists in the directory structure / libraries).

It is also impossible to descend into an embedded symbol. Should it be?

Comments?

Perhaps un-embedding a component should prompt for a file-name to save? (Defaulting to the one in specified in the page, if any)

We'd only need to save an un-embedded symbol if it doesn't exist, or is different to that found in the libraries.

There are lot of things that we could do with embedded symbols. Here some use cases:

1. Embedded symbol in the schematic, no symbol in the library
* open the symbol in a buffer (or in a temporary file)
* modify the symbol
  * save the symbol as a file
  * reembed the new modified symbol

2. Edit an instance of a symbol that is still available in a library
* embed the symbol
* modify the symbol
  * save the symbol as a file
  * reembed the new modified symbol

This would also work fine with symbols, that came from a symbol database
that is connected with component-library-command.

When embedding modified symbols, the symbol name should be modify.
e.g. EMBEDDED_symbolname_SHA1
Adding a hash to a modified embedded symbol would prevent any unwanted symbol
update to an older, unmodified symbol.
