Package: globals
================
Version: 0.10.0 [2017-04-16]
NEW FEATURES:
o Globals that are part of a formula are now identified.
o findGlobals(..., trace = TRUE) will now show low-level parse information
as the abstract syntax tree (AST) is walked.
SOFTWARE QUALITY:
o Enabled more internal sanity checks.
BUG FIXES:
o walkAST() could produce error "Cannot walk expression. Unknown object
type 'nnn'" for expressions of type 'builtin', 'closure' and 'special'.
Version: 0.9.0 [2017-03-09]
NEW FEATURES:
o Added option 'globals.debug', which when TRUE enables debugging output.
BUG FIXES:
o globalsOf(..., recursive = TRUE) would in some cases scan an incorrect
subset of already identified globals.
o globalsOf(..., recursive = TRUE) failed to skip objects part of package
namespaces that where defined via a local() statement.
Version: 0.8.0 [2017-01-14]
NEW FEATURES:
o globalsOf() identifies also globals in locally defined functions.
This can be disabled with argument recursive = FALSE.
o findGlobals() now takes both closures (functions) and expressions.
Version: 0.7.2 [2016-12-28]
BUG FIXES:
o c(x, list()) where x is a Globals object would give an error reporting
that the list does not have named elements.
Version: 0.7.1 [2016-10-13]
NEW FEATURES:
o Globals() and as.Globals() now accepts an empty list as input as well.
BUG FIXES:
o walkAST(quote( function(x=NULL) 0 )) would give a sanity check error due
to the NULL argument. Thank you GitHub user billy34 for reporting on this.
Version: 0.7.0 [2016-09-08]
NEW FEATURES:
o Added walkAST(), which can be used to tweak expressions.
o Added globalsByName() for locating and retrieving a set of known global
variables.
o Added c(), $<-(), names(), unique() for Globals objects.
o Improved as.Globals() for lists.
Version: 0.6.1 [2016-01-31]
NEW FEATURES:
o Now the error message of globalsOf(..., mustExist=TRUE) when it fails to
locate a global also gives information on the expression that is
problematic.
BUG FIXES:
o cleanup() for Globals did not cleanup functions in core package
environments named 'package:<name>'.
Version: 0.6.0 [2015-12-12]
NEW FEATURES:
o findGlobals() is updated to handle the case where a local variable is
overwriting a global one with the same name, e.g. { a <- b; b <- 1 }.
Now 'b' is correctly identified as a global object. Previously it would
have been missed. For backward compatibility, the previous behavior can
be obtained using argument method="conservative".
Version: 0.5.0 [2015-10-13]
NEW FEATURES:
o globalsOf() now returns attribute 'where' specifying where each global
object is located.
BUG FIXES:
o cleanup() now only drops objects that are *located* in one of the "base"
packages; previously it would also drop copies of such objects, e.g.
FUN <- base::sample.
Version: 0.4.1 [2015-10-05]
BUG FIXES:
o globalsOf() failed to return global variables with value NULL. They were
identified but silently dropped.
Version: 0.4.0 [2015-09-12]
NEW FEATURES:
o findGlobals() and globalsOf() gained argument 'dotdotdot'.
Version: 0.3.1 [2015-06-10]
o More test coverage.
Version: 0.3.0 [2015-06-08]
NEW FEATURES:
o Renamed getGlobals() to globalsOf().
Version: 0.2.3 [2015-06-08]
NEW FEATURES:
o Added [() for Globals.
o findGlobals() and getGlobals() gained argument 'substitute'.
o Added cleanup(..., method="internals").
Version: 0.2.2 [2015-05-20]
NEW FEATURES:
o Added Globals class with methods cleanup() and packagesOf().
Added as.Globals() to coerce lists to Globals objects.
Version: 0.2.1 [2015-05-20]
NEW FEATURES:
o getGlobals() gained argument 'mustExist' for controlling whether to give an
error when the corresponding object for an identified global cannot be
found or to silently drop the missing global.
o findGlobals() and getGlobals() gained argument 'method' for controlling
whether a "conservative" or a "liberal" algorithm for identifying true
globals should be used.
Version: 0.2.0 [2015-05-19]
o Moved globals function from an in-house package to this package.
Version: 0.1.0 [2015-02-07]
o Created.
