Previously, both the modifier and +any options to it were parsed between alias expansion and parameter +expansion (see zshexpn(1)), so they could neither be quoted nor be the +result of parameter expansion. Examples: 's=command; $s -V ls' and +'\command -V ls' now work as expected. + + +Changes from 5.2 to 5.3.1 +------------------------- + +There are only minor compatibility fixes between 5.3 and 5.3.1. + +It is possible to enable character width support for Unicode 9 by +configuring with `--enable-unicode9'; this compiles in some additional +tables. At some point this support may move into a module, in which +case the configure option will be changed to cause the module to be +permanently loaded. This option is not useful unless your terminal also +supports Unicode 9. + +The new word modifier ':P' computes the physical path of the argument. +It is different from the existing ':a' modifier which always resolves +'/before/here/../after' to '/before/after', and differs from the +existing ':A' modifier which resolves symlinks only after 'here/..' is +removed, even when /before/here is itself a symbolic link. It is +recommended to review uses of ':A' and, if appropriate, convert them +to ':P' as soon as compatibility with 5.2 is no longer a requirement. + +The output of "typeset -p" uses "export" commands or the "-g" option +for parameters that are not local to the current scope. Previously, +all output was in the form of "typeset" commands, never using "-g". + +vi-repeat-change can repeat user-defined widgets if the widget calls +zle -f vichange. + +The parameter $registers now makes the contents of vi register buffers +available to user-defined widgets. + +New vi-up-case and vi-down-case builtin widgets bound to gU/gu (or U/u +in visual mode) for doing case conversion. + +A new select-word-match function provides vim-style text objects with +configurable word boundaries using the existing match-words-by-style +mechanism. + +Support for the conditional expression [[ -v var ]] to test if a +variable is set for compatibility with other shells. + +The print and printf builtins have a new option -v to assign the output +to a variable. This is for bash compatibility but with the additional +feature that, for an array, a separate element is used each time the +format is reused. + +New x: syntax in completion match specifications make it possible to +disable match specifications hardcoded in completion functions. + Changes from 5.1.1 to 5.2 ------------------------- |
