* Big cleanup of the semantics of paths, strings, contexts, string
concatenation and string coercion. This was a big mess (see
e.g. NIX-67). Contexts are now folded into strings, so that they
don't cause evaluation errors when they're not expected. The
semantics of paths has been clarified (see nixexpr-ast.def).
toString() and coerceToString() have been merged.
Semantic change: paths are now copied to the store when they're in a
concatenation (and in most other situations - that's the
formalisation of the meaning of a path). So
"foo " + ./bla
evaluates to "foo /nix/store/hash...-bla", not "foo
/path/to/current-dir/bla". This prevents accidental impurities, and
is more consistent with the treatment of derivation outputs, e.g.,
`"foo " + bla' where `bla' is a derivation. (Here `bla' would be
replaced by the output path of `bla'.)

/* String concatenation and context nodes: in order to allow users to
|
||||
write things like
|
||||
|
||||
"--with-freetype2-library=" + freetype + "/lib"
|
||||
|
||||
where `freetype' is a derivation, we automatically coerce
|
||||
derivations into their output path (e.g.,
|
||||
/nix/store/hashcode-freetype) in concatenations. However, if we do
|
||||
this naively, we could introduce an undeclared dependency: when the
|
||||
string is used in another derivation, that derivation would not
|
||||
have an explicitly dependency on `freetype' in its inputDrvs
|
||||
field. Thus `freetype' would not necessarily be built.
|
||||
|
||||
To prevent this, we wrap the string resulting from the
|
||||
concatenation in a *context node*, like this:
|
||||
|
||||
Context([freetype],
|
||||
Str("--with-freetype2-library=/nix/store/hashcode-freetype/lib"))
|
||||
|
||||
Thus the context is the list of all derivations used in the
|
||||
computation of a value. These contexts are propagated through
|
||||
further concatenations. In processBinding() in primops.cc, context
|
||||
nodes are unwrapped and added to inputDrvs.
|
||||
|
||||

|
