CHANGES FROM PREVIOUS VERSIONS OF ZSH
-------------------------------------
New features in zsh version 3.1.7
---------------------------------
Further enhancements to new completion system:
- Comprehensive context-sensitive configuration vai `styles', which
can be set by the menu-driven front end in compinstall.
- General mechanism for setting patterns to be ignored in a completion;
overriding of patterns to be matched for functions
- New completers: _prefix to complete word before cursor, _ignored
to complete using words so far ignored (like $fignore but more
powerful), _history to complete words from shell history
- Multiple use of completers with different options, similalry splitting
of different types of completion (`tags') so they are considered with
different styles
- Many more supplied completions for standard commands which work out of
the box, and better handling of command line options/arguments which
behave in the usual way
- $fpath now set up to use installed functions by default; functions
can be loaded just by `autoload -U compinit; compinit'
- Much improved handling of nested quoting
- New LIST_PACKED and LIST_ROWS_FIRST completion options and corresponding
styles
- compctl library separated out (frozen but still supported)
- User-friendly introduction available at zsh website
http://sunsite.auc.dk/zsh/
Additions to complist listing library (coloured completion and menu
selection):
- Listings can be shown page by page (are by default for new completion)
- Menu selection allows full up and down scrolling of long lists
Other editing features:
- new parameters $PENDING, $MARK, $BUFFERLINES
- Easy display of a prompt from within an editing widget
Code parsing, storing and execution:
- Completely new system of storing code internally, greatly optimised
- Much less memory for shell functions etc.
- Can compile shell functions to .zwc `wordcode' functions for fast
loading
- Can create `digest' files of entire directories in .zwc format
Parameters:
- Floating point support added, similar to ksh93, `typeset -F' and
`typeset -E' declare floating point variables; usual C/Fortran-like
rules for integer/float conversion
- Mathematical library zsh/mathfunc contains all the standard mathematical
functions for use in arithmetical expressions
- Improved parsing of arithmetical expressions and better error messages
- Special parameters can be made local
- `typeset -h' hides specialness of parameters, either as parameter
attribute or when declaring new local variable
- Local parameters can now be exported as in other shells; new option
GLOBAL_EXPORTS on by default provides old behaviour that `typeset -x'
referred to global parameters.
- zsh/parameter module enhanced: now needed for new completion; parameters
provided have `-h' flag set so that they are hidden by `typeset', so
that existing functions don't need to be changed
- Quotes can be stripped from parameter values with ${(Q)...}, providing
reverse of ${(q...)...} facility
Globbing and pattern matching:
- Pattern matching rewritten for efficiency
- Supports `backreferences', i.e. extracting parenthesised chunks of
matches, e.g.
[[ $foo = (#b)(*/)[^/]* ]]
stores the part of $foo up to the last / in $match[1] and the indexes of
the match in $mbegin[1], $mend[1]. (#m) is also availabel to set $MATCH
to the entire match and corresponding $MBEGIN, $MEND: useful in
parameter substitutions like ${.../.../...}.
- (#s) and (#e) match start and end of pattern like ^ and $ in regular
expression, useful in complex expressions such as ((#s)|/)dirname((#e)|/)
and in parameter expressions.
- Depth-first/last listing of recursive glob lists
Functions etc.:
- `autoload -X' inside a function body instructs the shell to
bootstrap the function at that point
- `autoload +X fn' says load the function fn but don't execute it
- Prompt `themes' make customization of prompts easier
Modules:
- New hierarchical naming scheme for modules; supplied modules go into
zsh subdirectory, so zle becomes zsh/zle etc.; aliases supplied for
compatibility for existing code, but the new format should be used in
future.
- zmodload is more consistent between dynamicall and statically linked
shells
- zsh/zftp and its function suite support multiple sessions (zfsession
command); zftransfer allows transfer of files between two ftp sessions
with no local file; use styles for e.g. progress style; IPv6 supported;
recursive put `zfput -r' for uploads
- zsh/zpty module creates pseudoterminal and allows builtin `expect'-like
behaviour
Other:
- Test suite, not yet complete (`make test')
- use of Linux task limits
- Many fixes including output redirection with `setopt xtrace' and
other redirection fixes; NIS+ problem.
- Better null-command behaviour in sh and csh emulation
- Internal memory usage optimisations
New features in zsh version 3.1.6 (beta version)
------------------------------------------------
Note also the changes for 3.0.6, which include changes between 3.1.5. and
3.1.6.
New completion system via shell functions; massive degree of
programmability and configurability:
- ready-made function suite to use, see zshcompsys(1)
- approximate completion and spelling correction via completion
- control over matching for case-independence, partial word completion, etc.
- menu selection: choose a completion by moving the cursor
- coloured completion lists
- completion of filenames in quotes is now more reliable; splitting
quoted strings into command arguments is also possible.
Other editing changes:
- enhancements to function/editing interface: new parameters, numeric
arguments, string argument passing, reading keys from widgets.
- the old history-search-{back,for}ward behaviour and bindings have
returned (up to minor details).
- BASH_AUTO_LIST option to show completion list only on second key press.
- the ZBEEP parameter gives a string to output instead of beeping,
allowing you to have a visual bell.
History changes: new options HIST_NO_FUNCTIONS, HIST_EXPIRE_DUPS_FIRST,
HIST_FIND_NO_DUPS, HIST_IGNORE_ALL_DUPS, INC_APPEND_HISTORY,
HIST_SAVE_NO_DUPS, SHARE_HISTORY, allow better control of when history is
read and written and how duplicates are handled. New format for history
saves.
Associative arrays plus enhanced parameter substitutions to retrieve keys
and values.
Globbing changes:
- Case-insensitive and approximate globbing.
- Ordering and indexing of globbing matches, e.g. *(om[1]) picks
most recently modified file.
- General file mode qualifier with chmod(1)-like syntax, e.g. *(f:u+wx:)
New loadable modules:
- zftp, plus associated function suite, for turning your zsh session
into an FTP session too
- parameter, for examining and altering shell hash tables via an
associative array interface.
- mapfile, for reading and writing external files via an associative
array interface.
Debugging and prompt enhancements:
- $PS4 can contain %i for $LINENO as well as %N for script or function
names (default PS4 changed), also %_ for current shell structure
executing;
- Prompt truncation %<...< is now more flexible: it applies to a
whole section of the prompt, not just one escape. You need to put
%<< after the truncated escape to get the old behaviour.
- %20(l.yes.no) in prompts prints yes if at least 20 characters have
been output, else no (e.g. for outputting extra newlines).
Parameter and expansion changes
- `typeset -t MYPATH mypath' creates tied path/PATH-like variables
- `typeset -g' allows operations on parameters without making them local
- New expansions
- ${(t)param} prints type information for $param
- ${(P)param} treats value of $param as the name of a param to
substitute
- ${foo:q} can quote replaced parameter text from expansion
- ${foo/old/new} substitution, like bash; also (S) flag for shortest
match
- $foo[(b.2.i)bar] starts searching $foo for bar starting at 2nd match
Builtin and function changes
- stat module: `stat -H hash foo' gives you e.g. $hash[mtime]
- `autoload -U' autoloads functions without alias expansion.
Other new options:
- LOCAL_TRAPS allows signal traps to be local to functions (as in ksh).
- NO_RCS can now be turned on at any point in initialization files.
- NO_GLOBAL_RCS can force /etc/z* files after /etc/zshenv to be skipped.
(Please don't use this as an excuse to stuff more into /etc/zshenv!)
- Existing MAGIC_EQUAL_SUBST option is more useful; any argument containing
...=~...:~... will perform filename expansion on the ~ (previously,
the string before `=' had to look like a parameter name).
Configuration changes:
- Generation of signal names should be more reliable
- Customizable installation of shell functions from distribution.
New features in zsh version 3.0.6
---------------------------------
Most of these changes are designed to improve compatibility with zsh
version 3.1.6, the latest development release. However, this release also
fixes all known Year 2000 (Y2K) bugs in zsh 3.0.
History changes:
- whitespace between words is ignored in history searches.
- new option HIST_REDUCE_BLANKS removes extra whitespace in the stored
history.
- support for reading (but not writing) version 3.1.6 history files.
Globbing changes:
- the a, c, and m glob qualifiers can now test time in seconds.
- globbing of number ranges behaves more like character ranges in that
it can match a prefix of a number, e.g. `<1-5>*' matches 1, 2, 3, 4,
5, 17, 23skiddoo, 5986, etc., but not 6, 7, 8ball, 911, etc.
Parameter and expansion changes:
- expansion of ~ and other globbing flags via ${~param} do not depend
upon EXTENDED_GLOB (bug fix).
- nested parameter substitutions require braces (this was always the
documented behavior, but previous parsers didn't enforce it).
- quote only nested expansion, e.g. ${(f)"$(<file)"} reads complete
`file', then splits lines into array.
Builtin and function changes:
- `typeset -U' works on the colon-array version of linked parameters.
- `typeset +f' and `functions +' output the names (only) of functions.
- `emulate -L' has the effect of `setopt localoptions'.
- in fn1() { local foo; unset foo; foo=bar; }, foo is restored at local
level, whereas if the `unset foo' appeared in a nested function it
would have been restored at global level, which was presumably wrong.
- `foo=bar >&file' is a redirection, not a NULLCMD.
- any single complex command, such as `case ... esac', parses as if
semicolon-terminated (bug fix).
- the shell function `preexec', if defined, is run after parsing each
command line but before executing the command.
Other changes:
- the option PRINT_EIGHT_BIT causes zsh to emit raw bytes in prompts
and completion lists even if the system ctype(3) package says that
those bytes are not "printable."
Debugging enhancements:
- LINENO is now very much more useful in scripts and functions and is
reported correctly in most error messages.
- ERREXIT behavior is now consistent with newer Bourne-like shells,
e.g. with respect to `if' tests that fail.
Configuration changes:
- Large file and 64-bit integers on 32-bit machines supported where
provided by OS.
- a few more system features, such as getpwnam/getpwuid, are tested for.
New features in zsh version 3.1 (beta version)
