lobstr 1.2.0

New src() function for exploring srcref and srcfile objects. We’ve documented all we know about srcrefs in ?src.
obj_size(), obj_addrs(), and sxp() no longer error with “bad binding access” when inspecting environments with non-standard bindings such as those created by for loops or immediate bindings (#48).
sxp(expand = "environment") no longer shows the internal _frame and _hashtab structures. Instead, it now shows promise expressions without forcing them. This change was necessary to make lobstr compliant with R’s public C API.
General progress towards conformance to the public C API of R.

lobstr 1.1.3

Changes for compliance with R’s public API. The main consequence is that lobstr no longer reports the truelength property of vectors.

We also changed the named indicator to refs:n, where n can take the values: 0 (corresponding to NO_REFERENCES returning 1), 1 (corresponding to both NO_REFERENCES MAYBE_SHARED returning 0), and 2+ (MAYBE_SHARED returning 1).

Switched to cpp11 from Rcpp.
Relicensed as MIT (#51).
obj_size() and sxp() now support non-nil terminated pairlists.
obj_size() now displays large objects with KB, MB, etc (#57, #60), and no longer returns NA for objects larger than 2^31 bytes (#45).
obj_sizes() now computes relative sizes correctly (without meaningless floating point differences).
ref() lists all contents of environments even those with names beginning with . (@krlmlr, #53).
New, experimental tree() function as alternative to str() (#56).

ref() now handles custom classes properly (@yutannihilation, #36)
sxp() is a new tool for displaying the underlying C representation of an object (#38).
obj_size() now special cases the ALTREP “deferred string vectors” which previously crashed due to the way in which they abuse the pairlist type (#35).
