Some more of the invocations are tested in this change:
- bad switches
- errors in configuration files
- regular command, configuration and init command ordering
- persistence of variables over command invocation.
- interactive and login switch use
- terminal exit code return
- version request
There are sure to be other invocations that should be tested, but
these give a fair number of them a go.
The new '-C' initial command needs some tests, and as there are no
tests just yet for the command invocation, this change adds a harness
and calls it from the high-level tests in the Makefile.
The tests are similar in style to the other high level tests, in that
we capture the output and compare it to that which we expect. The
harness itself is written in bash - sorry - because we're testing the
fish shell's invocation, and trying to do that with the fish we've
just built wouldn't actually make for a very useful test when things
go wrong.
The 'tests/invocation.sh' script can be executed manually, or as part
of the 'make test' target, to make it easy to use both as part of the
development and as part of automation.
The harness has only been tested on linux with bash 4.3.11, and requires
grep and sed. Although not tested with OS X, I believe I have avoided
the syntax which is inconsistent.
The tests added here cover just the initial command's basic execution,
and when it is mixed with the regular '-c' command.
In order to allow the execution of commands before dropping to an
interactive prompt, a new switch, '-C' or '--init-command' has been
added to those switches that we accept.
The documentation has been updated correspondingly.
The original code only supported a single command list to be executed,
and this command list terminates the shell when it completes. To allow
the new command list to preceed the original one, both have been
wrapped in a new container class 'command_line_switches_t'. This is
then passed around in place of the list of strings we used previously.
I had considered moving the interactive, login and other command line
switch states into this container, but doing so would change far more
of the code, moving the structure to be available globally, and I
wasn't confident of the impact. However, this might be a useful thing
to do in the future.
A new function, run_command_list, was lifted from the prior execution
code, and re-used for both the initial command and the regular command
execution.
We now have a builtin that can do URL escaping so use it. I can't find
any uses of our private `__fish_urlencode` function in any Oh-My-Fish or
Fisherman code so remove it.
We need a way to encode arbitrary strings into valid fish variable
names. It would also be nice if we could convert strings to valid URLs
without using the slow and hard to understand `__fish_urlencode` function.
In particular, eliminating the need to manipulate the locale.

As part of addressing #1310 I decided it makes more sense to replace
`current-function` with just `function`, etc., because I'm going to add
flags to let the user specify which stack level they are interested in.
With the default being zero or the "current" level.
This just removes every invalid index.
That means with `set foo a b c` and the "show" function from tests/expand.in:
- `show $foo[-5..-1]` prints "3 a b c"
- `show $foo[-10..1]` prints "1 a"
- `show $foo[2..5]` prints "2 b c"
- `show $foo[1 3 7 2]` prints "3 a c b"
and similar for command substitutions.
Fixes#826.
This is another step to resolving issue #1310. It makes
`fish_breakpoint_prompt` a replacement for `fish_prompt` if it is defined
and we're presenting a prompt in the context of a `breakpoint` command.
This implements `status is-breakpoint` that returns true if the current
shell prompt is displayed in the context of a `breakpoint` command.
This also fixes several bugs. Most notably making `breakpoint` a no-op if
the shell isn't interactive. Also, typing `breakpoint` at an interactive
prompt should be an error rather than creating a new nested debugging
context.
Partial fix for #1310
This does several things. It fixes `builtin_function()` so that errors it
emits are displayed. As part of doing that I've removed the unnecessary
`out_err` parameter to make the interface like every other builtin.
This also fixes a regression introduced by #4000 which was attempting to
fix a bug introduced by #3649.
Fixes#4139
Running the tests on travis revealed that some compilers (or at least
with some options) call the wrong struct constructor if there is more
than one struct with the same name but differing definitions.
