A couple things went wrong with `env -u HOME USER=x ./fish -c ''`
We failed to check that `pw` isn't NULL leading to a crash when USER is
bogus. After fixing that we were not left with both variables in a
correct state still.
We now go back and force fish to dig up a working USER when we notice
this and then get both set successfully. Fixes#3599
I hate doing this but I am tired of touching a fish script as part of
some change and having `make style` radically change it. Which makes
editing fish scripts more painful than it needs to be. It is time to do
a wholesale reformatting of these scripts to conform to the documented
style as implemented by the `fish_indent` program.
This augments the previous change for issue #3346 by adding an error
message when an invalid integer is seen. This change is likely to be
controversial so I'm not going to squash it into the previous change.
The `test` builtin currently has unexpected behavior with respect to
expressions such as `'' -eq 0`. That currently evaluates to true with a
return status of zero. This change addresses that oddity while also
ensuring that other unusual strings (e.g., numbers with leading and
trailing whitespace) are handled consistently.
Fixes#3346
Only in one instance would test as `[` have the the errors formatted
as "[: foo". This fixes that. When trying to track down the source of
an error this could lead someone astray.
make clean was outputting misleading messages due to our
recursive invocation of make in the pcre directory, even if
that directory has no Makefile. This can easily come about if
the ./configure script determines we have a system installed PCRE.
This change simply checks for the presence of the Makefile in
the PCRE directory before invoking recursive make, for the clean
and distclean targets.
Fixes#3586
This might be a bit over the top, but getting the information that a default priority threshold is used without knowing what that value is or how to find out might not be so useful after all. Thus, change the completion to include this information dynamically.
Currently, the ./configure script generated by autotools will
test if the configure.ac script is newer than its output configure
script, and if so, run autoconf to rebuild it. However autoconf
is no longer sufficient because we have some m4 macros. So now
run autoreconf --no-recursive (per #3572)
This commit does a few things:
- Switches to C++11 as the language dialect
- Eliminates the Release_C++11 configuration (now C++11 is default)
- Switches to libc++ from libstdc++, since the libstdc++ that ships
with Xcode does not support C++11
The existing code is inconsistent, and in a couple of cases wrong, about
dealing with strings that are not valid ints. For example, there are
locations that call wcstol() and check errno without first setting errno
to zero. Normalize the code to a consistent pattern. This is mostly to
deal with inconsistencies between BSD, GNU, and other UNIXes.
This does make some syntax more liberal. For example `echo $PATH[1 .. 3]`
is now valid due to uniformly allowing leading and trailing whitespace
around numbers. Whereas prior to this change you would get a "Invalid
index value" error. Contrast this with `echo $PATH[ 1.. 3 ]` which was
valid and still is.
Some key bindings were updated in fish 2.4.0 but in some cases the
documentation does not correctly reflect the actual behavior. This
commit attempts to fix that.
Builtin commands that validate var names should use a consistent
mechanism. I noticed that builtin_read() had it's own custom code that
differed slightly from wcsvarname().
Fixes#3569
My previous change removed one place where is_wchar_ucs2() was used and
replaced it with compile time tests. This change does the same for the
other uses.
On Cygwin there are two narrowing conversions at line 931 in
src/fish_tests.cpp due to the code assuming a wchar_t is four bytes.
Obviously that's wrong but only became an issue with the pending change to
switch to C++11. The problematic values aren't actually used on Windows
because the tests that would use them are bypassed if is_wchar_ucs2()
returns true. This change predicates that code on a compile time rather
than a run time test.
