Changes since 5.0.0
|
||||
-------------------
|
||||
|
||||
Numeric constants encountered in mathematical expressions (but not other
|
||||
contexts) can contain underscores as separators that will be ignored on
|
||||
evaluation, as allowed in other scripting languages. For example,
|
||||
0xFFFF_FFFF, or 3.141_592_654.
|
||||
|
||||
"functions -T" turns on tracing for the specified function(s) only,
|
||||
similar to "functions -t" except that tracing is turned off for any
|
||||
functions called from the specified one(s) that don't also have the -t
|
||||
or -T flag.
|
||||
|
||||
The option FORCE_FLOAT has been added to force all arithmetic constants
|
||||
to be treated as floating point. This is most useful locally within
|
||||
functions or scripts performing floating point calculations.
|
||||
|
||||
Individual pattern characters can be disabled. For example, to allow '^'
|
||||
to be an ordinary character even if the option EXTENDED_GLOB is set, use
|
||||
"disable -p '^'".
|
||||
|
||||
The variable editing builtin vared can be given custom editing widgets
|
||||
for initialisation and finishing.
|
||||
|
||||
The line editor's capability for listening on file descriptors
|
||||
additional to the terminal has been enhanced so that the handler for
|
||||
such file descriptors can be a line editor widget. Previously the
|
||||
handler always behaved as a standard shell function.
|
||||
|
||||
Hooks for adding history (the function zshaddhistory and the
|
||||
array zshaddhistory_functions) can return status 2 to indicate that
|
||||
history is to be saved internally within the shell but not written.
|
||||
|
||||
In file completion, the recursive-files style can be set to an array of
|
||||
patterns to match against "$PWD/". In any matched location, it is
|
||||
possibly to complete files in arbitrarily deep subdirectories without
|
||||
needing to type the directory prefix. See example in the zshcompsys
|
||||
manual.
|
||||
|
||||
The _user_expand completer now allows expansion functions in the
|
||||
user-expand files to return a string in REPLY that will be used to name
|
||||
the set of expansions returned.
|
||||
|
||||
The parameter HISTORY_IGNORE may be set to a pattern which matches
|
||||
lines in the internal history that are to be omitted from the history
|
||||
file at file write time. This differs from history changes made in
|
||||
the zshaddhistory hook or by the HIST_IGNORE_* options, all of which
|
||||
take effect immediately on the internal history list itself.
|
||||
|
||||
The parameter ZLE_RPROMPT_INDENT can be set to 0 to remove the space
|
||||
before the right hand side of the screen (this causes problems with
|
||||
some terminals). It is not special and is not set by default; the
|
||||
effect in that case is as if it was 1, as in previous versions.
|
||||
|
||||
If the option EXTENDED_GLOB is in effect, it is possible to force
|
||||
globbing within conditional code using the [[ ... ]] syntax by flagging
|
||||
that a certain string is a glob using the (#q) glob qualifier syntax.
|
||||
The resulting glob is treated as a single argument. For example,
|
||||
[[ -n *.c(#qN) ]] tests whether there are any .c files in the current
|
||||
directory.
|
||||
|
||||
In prompt strings, the %N(l.true.false) conditional (line length) and
|
||||
the %N<..< and %N>..> truncation operators now accept negative values
|
||||
of N, which count the remaining space to the opposite margin (positive
|
||||
values of N still count the space used since the start of the prompt).
|
||||
In PS1 and PROMPT, this counts to the right margin, whereas in RPS1 and
|
||||
RPROMPT, it counts to the left margin (not to the opposite prompt).
|
||||
|
||||
Another new prompt feature is the %. escape within time strings, for
|
||||
example %D{%H:%M:%S.%.}. It provides zero-padded decimal fractions of
|
||||
second; by default milliseconds are shown, but the number of digits may
|
||||
be indicated from 1 to 6, e.g. "%6.". (Note this is part of the
|
||||
extensions to strftime() formats rather than basic prompt escapes.)
|
||||
|
||||
The operators :^ and :^^ in parameter substitution allow for array
|
||||
zipping in the form ${name:^array}. With the :^ operator, all entries
|
||||
in $name and $array will be output in alternating order. With :^ the
|
||||
longer array is trimmed whereas the :^^ operator repeats the shorter
|
||||
array enough to match the longer array.
