target class

[wlandau]

• cmd field.
• All dependency hashes:
  • cmd$hash().
  • Hashes of the dependencies of cmd from hash_envir().
  • Hashes of the targets directly upstream.
• Names of the targets directly upstream.
• Delegate pkgs() and eval() to cmd.
• Field for the return value.
• Other metadata such as runtime and seed. Need to think about organization.

[wlandau]

should track pre-build and post-build metadata separately

[wlandau]

Almost done. Need #5.

[wlandau]

Need to decompose fields.

• key
• cmd (already has subfields)
• file (already has subfields)
• result
  • value
  • seconds
  • warnings
  • error
• settings
  • format
  • seed

[wlandau]

result and settings should be classes of their own.

[wlandau]

After that is done, a target should be able to save itself without a data store class. Only the metadata needs to be a class, not the whole store.

[wlandau]

Done as a general issue. Offloading to sub-issues.
