Use $USER, prompt_hostname, string
Update to use correct color names such as magenta over purple.
Use bright color variants instead of bold in some cases.
Fixes display of version in documentation header. A shell-style variable
instead of a Makefile-style variable left it displayed as
ISH_BUILD_VERSION.
(cherry picked from commit 1e234f492c)
My earlier attempt with commit 851e449 to eliminate all the compiler
warnings about mixing signed and unsigned ints in an expression
introduced a subtle bug. This fixes that mistake.
Fixes#3488
(cherry picked from commit 075be74cc4)
This reverts commit dcb39af8c0.
It breaks building the documentation because splitting the sed invocation
in the `lexicon_filter` target from the preceding `if` block means the
`WORDBL` and `WORDBR` shell vars aren't available.
(cherry picked from commit 100a0ea549)
Regenerated with current autoconf tests for OS X El Capitan.
This avoids portability problems introduced with
8b9102d9fe and partially reverts that
commit.
Update the CHANGELOG to more accurately reflect what will be included in
the 2.4.0 release vis-a-vis the `history` command behavior.
I noticed that the compiler was emitting some harmless warnings related
to the history changes so deal with those as well.
This modifies the code path for `set PATH` and `set CDPATH` to emit an
easier to understand warning when an entry in those vars is invalid. For
example
$ set PATH $PATH /tmp/arglebargle
set: Warning: $PATH entry "/tmp/arglebargle": No such file or directory
$ mkdir /tmp/d
$ chmod 0 /tmp/d
$ set PATH $PATH /tmp/d
set: Warning: $PATH entry "/tmp/d": Permission denied
$ touch /tmp/x
$ set PATH $PATH /tmp/x
set: Warning: $PATH entry "/tmp/x": Not a directory
Fixes#3450
* Fix building on Android by avoiding getpwent() if missing with autoconf check
The getpwent() function does not link when building for Android,
and user names on that platform are not interesting anyway.
People regularly ask how to make abbreviations global (i.e., private to
a fish session) rather than universal. So explain how to do so in the
`abbr` man page.
Fixes#3446
