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
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.
Fixes#4150
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 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
Users continue to be surprised that fish auto splits/joins three env
vars but not other similar vars. Mention this in the tutorial to make it
less likely new users are surprised by this behavior.
Fixes#4009
It still performs the assignment even if the command substitution
returned unsuccessfully - `set foo (echo bar; false)` returns 1 but
sets $foo to bar.
Also use `type -p` instead of `which`.
Another change related to issue #3985. I forgot to includes this in my
previous two changes related to to consistently returning status 121
when any command, not just `string`, is handed invalid args.
This primarily replaces "STATUS_BUILTIN_OK" with "STATUS_CMD_OK" and
"STATUS_BUILTIN_ERROR" with "STATUS_CMD_ERROR". That is because we want
to make it clear these status codes are applicable to fish functions as
well as builtins. Future changes will make it easier to use these
symbols and values in functions.
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.
This is the first step in addressing issue #3965. It renames some of the
functions involved in validating variable and function names to clarify
their purpose. It also augments the documentation to make the rules for
such identifiers clearly documented.
- 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.
