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.
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.
Fixes#4150
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 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 changes all of the builtins to behave like `string` to return
STATUS_INVALID_ARGS (121) if the args passed to the command don't make
sense. Also change several of the builtins to use the existing symbols
(e.g., STATUS_CMD_OK and STATUS_CMD_ERROR) rather than hardcoded "0"
and "1" for consistency and to make it easier to find such values in
the future.
Fixes#3985
Per discussion in PR#3998 to review adding a `--filter` flag to `string
replace` rename the same flag in the `string match` subcommand to avoid
confusion about the meaning of the flag.
Discussion in issue #3295 resulted in a decisions to rename the
functions --metadata flag to --details.
This also fixes a bug in the definition of the short flags for the
`functions` command. The `-e` flag does not take an argument and
therefore should not be defined as `e:`. Notice that the long form,
`--erase`, specifies `no_argument`. This discrepency happened to work
due to a quirk of how the flag parsing loop was written.
The bind mode names can be, and are, used in the construction of fish
variable names. So don't allow users to use names that are not legal as
a variable name. This should not break anything since, AFAICT, no
existing fish scripts, including those provided by Oh-My-Fish and
Fisherman define bind modes that would not be legal with this change.
Fixes#3965
This is to fix tests on Travis, since that stores the commit message in an environment variable.
`env | grep MANPATH` of course picks it up and generates unwanted output.
Yes.
Fixes invalid character in variable name $fish_cursor_replace-one (used by fish_vi_cursor[_handle]) by renaming bind mode 'replace-one' to 'replace_one'.
Reviewing a PR for a completion script caused me to look at the
implementation for the `__fish_complete_directories` function. Which in
turn lead me to create this change to improve its implementation and add
unit tests for the function.
- Error out if anything that is not a PID is given
- Otherwise background all matching existing jobs, even if not all
PIDs exist (but print a message for the non-existing ones)
Fixes#3909.
If the first word of the alias body ends with a semicolon we need to
strip that character, and otherwise escape the extracted command, to
ensure the subsequent function definition is valid.
Fixes#3860
The previous change neglected to consider that numbers too large for the
long long datatype will result in calling strerror(ERANGE) whose return
value can vary depending on the platform. Which breaks the unit test.
This puts a hard upper bound of 10 MiB on the amount of data that read
will consume. This is to avoid having the shell consume an unreasonable
amount of memory, possibly causing the system to enter a OOM condition,
if the user does something non-sensical.
Fixes#3712
