Package: listenv
================

Version: 0.8.0 [2019-12-05]

SIGNFICANT CHANGES:

 * S3 method lengths.listenv() is no longer exported.

NEW FEATURES:

 * Made several error messages more informative.  The downside is that those
   messages are no longer translated (because they are no longer aligned with
   built-in R error messages which have translations)
 
BUG FIXES:

 * parse_env_subset(x[1, names]) on a listenv 'x' matrix would throw error
   'Error in if (any(i < 0)) { : missing value where TRUE/FALSE needed' if
   one of the elements in 'names' specifies a non-existing column name.
   
 * parse_env_subset(x[]) on a listenv 'x' would throw an error on
   "Invalid subset: 'x[]'".

 * parse_env_subset(x[names]) on a listenv 'x' would throw an error on
   'length(x) = 2 > 1' in coercion to 'logical(1)' when length(names) > 1
    and _R_CHECK_LENGTH_1_LOGIC2_=true.

 * parse_env_subset(x[1,idxs]) on a listenv 'x' would throw an error on
   'length(x) = 2 > 1' in coercion to 'logical(1)' with length(idxs) > 1
   and _R_CHECK_LENGTH_1_LOGIC2_=true.

 * parse_env_subset(x[[names]]) on a regular environment 'x' with
   length(names) > 1 would not throw an error, whereas x[[names]] would.

 * parse_env_subset(x[[1]]) on a regular environment 'x' would not throw
   an error, whereas x[[1]] would.


Version: 0.7.0 [2018-01-21]

NEW FEATURES:

 * Now it is possible to set the dimension on an empty list environment without
   first resizing it with length(), e.g. x <- listenv(); dim(x) <- c(2, 3).

 * Now it is possible to remove multiple elements by assigning NULL, e.g.
   x[c(2:3, 10)] <- NULL and x[, "B"] <- NULL.

 * Added lengths() for list environments.  Requires R (>= 3.3.0).

 * dim_na(x) <- dims, where 'dims' contain exactly one missing value, will
   set the "missing" dimension based on the length of 'x' and the other
   dimensions specified, e.g. with length(x) == 6, dim_na(x) <- c(2, NA) will
   set dim(x) <- c(2, 3).  This works for all types of object to which
   dimensions can be assigned - not only list environments.

 * Added is.matrix(), is.array(), as.vector() and as.matrix() for list
   environments.

BUG FIXES:

 * print() on a named, empty list environment would output an empty string.
 
 * Removing an element from a list environment did not remove dimensions,
   e.g. x$a <- NULL.

DEPRECATED AND DEFUNCT:

 * Function map() has been renamed to mapping() and same for the corresponding
   replacement function.  The map() and map<-() functions will soon be
   deprecated and eventually defunct.

 * x <- listenv(length = n) is defunct; use x <- listenv(); length(x) <- n.

 
Version: 0.6.0 [2015-12-27]

NEW FEATURES:

 * Added support for multi-dimensional subsetting of list environments
   just as for list.

BUG FIXES:

 * parse_env_subset(x[[idx]]) for list environment 'x' and index 'idx' claimed
   x[[idx]] exists as long as idx in [1,length(x)] but it forgot to check if
   element really existed, which may not be true if 'x' has been expanded.
 
 
Version: 0.5.0 [2015-10-30]

NEW FEATURES:

 * Add support for assigning elements when creating list environment
   similarly how to lists work, e.g. x <- listenv(a = 1, b = 2).

 * length(x) <- n now expand/truncate a list environment.

 * Added unlist() and all.equal() for list environments.

DEPRECATED AND DEFUNCT:

 * Deprecated x <- listenv(length = n); use x <- listenv(); length(x) <- n.

BUG FIXES:

 * as.listenv(x) would drop NULL elements in 'x'.

 * x[idxs], x[name] <- y and x$<name> <- y would introduce NA names for
   non-named list environments.
 
 
Version: 0.4.0 [2015-08-08]

NEW FEATURES:

 * Added as.listenv().

 * CONSISTENCY: Assigning NULL now removes element just as lists,
   e.g. x$a <- NULL. To assign value NULL, do x['a'] <- list(NULL).

 * Added support for subsetting with [(), which returns another
   list environment, e.g. x[2:3], x[-1] and x[c(TRUE, FALSE)].

 * Added [<- assignment, e.g. x['a'] <- 1 and x[2:3] <- c(3,8).

 * CLEANUP: Dropped stray debug code.
 
 
Version: 0.3.0 [2015-05-23]

CODE REFACTORIZATION:

 * Package no longer depends on other packages.
 
 
Version: 0.2.4 [2015-05-22]

NEW FEATURES:

 * Added helper function parse_env_subset().
 
 
Version: 0.2.3 [2015-05-21]

NEW FEATURES:

 * print() on listenv() handles empty and no-named listenv:s better.
 
 
Version: 0.2.2 [2015-05-20]

NEW FEATURES:

 * Now listenv(length = ...) always allocates internal variables.
 
 
Version: 0.2.1 [2015-05-19]

NEW FEATURES:

 * get_variable() gained argument 'mustExist'.
 
 
Version: 0.2.0 [2015-05-19]

SIGNFICANT CHANGES:

 * Moved list environments from an in-house package to its own package.
 
 
Version: 0.1.4 [2015-05-02]

NEW FEATURES:

 * Added print() for listenv:s.

CODE REFACTORIZATION:

 * Using tempvar() of R.utils.
 
 
Version: 0.1.0 [2015-02-07]

 * Created.
