| Summary | 0001976: specify array variables and syntax | ||||
| Description | POSIX sh specifies one array per function, the argument array many sh implementations support having array variables past the argument array due to posix shell specifying a syntax for the argument array, sh implementations with array extensions naturally landed on similar and compatible syntax mksh, ksh93, bash, zsh, osh, yash, all support the following syntax: foo=(a b "c d" e) foo+=(f g) "${foo[@]}" # a b "c d" e f g "${foo[*]}" # "a b c d e f g" "${foo[expr]}" # indexed by expr, where expr is evaluated like $(( expr )) "${#foo[@]}" # 6, the lenght of foo additionally, mksh, ksh, and zsh, support declaring arrays as such: set -A name -- values notably ksh does not implement the name=(values) syntax, but has no other syntax that would conflict with it either ash and dash do not currently implement any sort of arrays, but also have no syntax that conflicts with the existing extensions | ||||
| Desired Action | rough first draft of changes: XBD 4.25: specify varname=(value) as assigning an array variable specify varname[expr]=value as assigning a entry in the array XCU: 2.5: specify array variables as containing an array of arbitrary byte sequences, except for null byte XCU: 2.6.2: specify ${parameter[@]} and ${parameter[*]} expansions matching 2.5.2 special parameters specify ${parameter[expr]} expansion, where expr is arithimetically expanded, then parameter is expanded matching 2.5.1 positional parameters | ||||
