This fixes a stupid bug in my previous commit to standardize on a new
`list_to_array_val()` function. This adds a unit test to keep this from
regressing.
This is the first step in implementing a better abstraction for handling
fish script vars in the C++ code. It implements a new function (with two
signatures) to provide a standard method for construct the flag string
representation of a fish script array.
Partial fix for #4200
The count command should not treat any flag specially. Not even `-h` and
`--help`. It should simply return a count of the number of arguments it
received.
Fixes#4189
Completion strings, especially the description, might contain characters,
such as backspace, which make it impossible to calculate the width of
the string.
Fixes#4179
Var `___git_ps_color_suffix_done` is supposed to be
`___fish_git_prompt_color_suffix_done`. This bug was found by an
experimental change to detect the use of undefined variables (#4163).
Similarly, we should simply test whether `__fish_git_prompt_showcolorhints`
is set rather than set to a non-empty string.
The `read` command `-m` and `--mode-name` vars are now deprecated and do
nothing other than result in a warning message. The `read` command now
honors the `FISH_HISTORY` var that is used to control where commands are
read from and written to. You can set that var to the empty string to
suppress the use of both history files. Or you can set it to a history
session ID in which case that will limit the `read` history that is
available.
Fixes#1504
Don't import the bash history if the user has specified that a non-default
fish history file should be used. Also, rename the var that specifies
the fish history session ID from `FISH_HISTFILE` to `FISH_HISTORY`.
Fixes#4172
Using the FISH_HISTFILE variable will let people customise the session
to use for the history file. The resulting history file is:
`$XDG_DATA_HOME/fish/name_history`
Where `name` is the name of the session. The default value is `fish`
which results in the current history file.
If it's set to an empty string, the history will not be stored to a
file.
Fixes#102
Because the 'getopt' library differs between systems, it's likely
that there will be different output. This is the case between the
GNU-based Linux and the BSD-based Darwin, for the 'getopt' library,
it seems. It causes the tests to produce different results.
To allow us to test, and check for regressions, on the different
platforms, the invocation code has been updated to allow a
system-specific suffix to be used on the test files. If this suffix
is found, the test will also be flagged as being system-specific
which should ensure the change in behaviour is noted.
The Travis macOS test systems do not appear to have colordiff present, so any
failures would mean that no output would be shown. This may also be a
problem for the other test scripts as well, but the invocation tests are
the ones being affected here.
We change our behaviour to downgrade to the plain diff tool if colordiff is
not present.
The invocation tests were not especially clear on how they should be
used, without reading the code. And who really wants to do that? So,
a description of what the test does (and thus what each file is) is
now present in the file prologue comment.
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.
