Chrome says that's better, presumably because it can then tell how
large the image is before it's loaded. Not that this tiny image really
is a massive problem, but let's be good, not acceptable.
This led to pydoctheme.css being included *twice*, which led to
everything it included being included twice, which was annoying in
firefox when playing with the styles.
I don't *think* it had any performance impact?
The file is called "config.fish", not "init.fish". We'll call it
"configuration" now.
"Initialization" might be slightly more precise, but in an irritating
way.
Also some wording improvements to the section. In particular we now
mention config.fish *early*, before the whole shebang.
Otherwise there's this weird *gap*, where the sections are narrow even
tho there's plenty of space?
So you have this screen layout:
```table
| sidebar | text |
| sidebar | narr |
| sidebar | ower |
| sidebar | than |
| sidebar | need |
| sidebar | ed |
```
For some gosh-forsaken reason.
Prior to this change, a function with an on-job-exit event handler must be
added with the pgid of the job. But sometimes the pgid of the job is fish
itself (if job control is disabled) and the previous commit made last_pid
an actual pid from the job, instead of its pgroup.
Switch on-job-exit to accept any pid from the job (except fish itself).
This allows it to be used directly with $last_pid, except that it now
works if job control is off. This is implemented by "resolving" the pid to
the internal job id at the point the event handler is added.
Also switch to passing the last pid of the job, rather than its pgroup.
This aligns better with $last_pid.
This is an attempt to make these more visible - the intro section
explains what this is, and then we mention where to go, and after that
we go into installation and stuff.
I don't think putting "where to go" *after* the installation
instruction is correct, but maybe it is? For the time being, we keep
the order as it is.
fish_private_mode is active if set to something non-empty, but the docs
suggested checking if it is set at all. Switch the docs to match the
implementation through `test -n "$fish_private_mode"`
Fixes#8001
Apparently new sphinxen want to create an *additional* section
directory, so things end up in /usr/share/fish/man/man1/1, instead of /usr/share/fish/man/man1
Why? No idea.
I can't reproduce it but I'm told this section fixes it.
Fixes#7996
It's a bit weird to *have* to fire up a browser to get fish_config to
choose a prompt.
So this adds a `prompt` subcommand to `fish_config`:
- `fish_config prompt list` shows all the available prompt names
- `fish_config prompt show` demos the available sample prompts
- `fish_config prompt choose` sources a prompt
- `fish_config prompt save` makes the choice permanent
A bare `fish_config` or `fish_config browse` opens the web UI.
Part of #3625.
TODO: This shows the right prompt on a new line. Showing it in-line is awkward
to do because we'd have to move it to the right.
This prints a description of the "host". Currently that's
`(chroot:debianchroot) $USER@$hostname`
with the chroot part when needed.
This also switches the default and terlar prompts to use it, the other
prompts have slightly different coloring or logic here.
When building the docs with an old sphinx (like e.g. on Debian), this
would break links in the search results.
This happens because we've nabbed the searchtools.js from a sphinx to
add our special handling of short builtins like "and", "end", "cd" (as
part of #7757).
I don't believe this will change *a lot* in practice, so it's probably
still okay, but this hack is still worthwhile.
See #7946
Otherwise this would look ugly by stopping the gradient after the
content, so in e.g. the `end` or `false` page it would leave an ugly stripe at
the bottom.
* math: Make function parentheses optional
It's a bit annoying to use parentheses here because that requires
quoting or escaping.
This allows the parens to be omitted, so
math sin pi
is the same as
math 'sin(pi)'
Function calls have the lowest precedence, so
math sin 2 + 6
is the same as
math 'sin(2 + 6)'

It's not super clear what $SHLVL is useful for, but the current
definition is essentially
"number of shells in the parent processes + 1"
which isn't *super useful*?
Bash's behavior here is a bit weird in that it increments $SHLVL
basically always, but since it auto-execs the last process it will
decrement it again, so in practice it's often not incremented.
E.g.
```
> echo $SHLVL
1
> bash -c 'echo $SHLVL; bash'
2
>> echo $SHLVL
2
```
Both bashes here end up having the same $SHLVL because this is
equivalent to `echo $SHLVL; exec bash`. Running `echo $SHLVL` and then
`bash -c 'echo $SHLVL'` in an interactive bash will have a different
result (1 and 2) because that doesn't *exec* the inner bash.
That's not something we want to get into, so what we do is increment
$SHLVL in every interactive fish. Non-interactive fish will simply
import the existing value.
That means if you had e.g. a bash that runs a fish script that ends up
opening a new fish session, you would have a $SHLVL of *2* - one for the
bash, and one for the inner fish.
We key this off is_interactive_session() (which can also be enabled
via `fish -i`) because it's easy and because `fish -i` is asking for
fish to be, in some form, "interactive".
That means most of the time $SHLVL will be "how many shells am I deep,
how often do I have to `exit`", except for when you specifically asked
for a fish to be "interactive". If that's a problem, we can rethink it.
Fixes#7864.
This breaks apart the massive "index" document into
1. An "index" document that explains how to install and set up fish
and links to the other documents
2. A "fish-language" document that describes the syntax and semantics
of the language
3. A "fish-interactive" document that describes how to use fish
interactively
No change to the content has been made, only the parts have been moved
from index and some of the formatting (links and header levels) were
fixed.
See #7348.
Unlike links, these are checked by sphinx and it complains if they
don't match.
Also they have a better chance of doing something useful in outputs
other than html.
The "classic" theme is a mostly useless wrapper around the basic theme
that just adds a collapsible sidebar (that we no longer have).
Moving to basic directly drops a layer of indirection and a file that
needs to be transferred over the net.
Same thing goes for "default.css" which literally just includes
classic.css (WHYYYY???)
(also this removes some useless javascript)
Unfortunately this has both stopwords and a length limit, and things
like "and" just are tough to search.
So what we do is leave everything as it is, but when a search fails,
we show a list of things that are hard to search for, currently that's
"and", "for", "if" and such.
Fixes#7757.
The user may write for example:
echo foo >&5
and fish would try to output to file descriptor 5, within the fish process
itself. This has unpredictable effects and isn't useful. Make this an
error.
Note that the reverse is "allowed" but ignored:
echo foo 5>&1
this conceptually dup2s stdout to fd 5, but since no builtin writes to fd
5 we ignore it.
After commit 6dd6a57c60, 3 remaining
builtins were affected by uint8_t overflow: `exit`, `return`, and
`functions --query`.
This commit:
- Moves the overflow check from `builtin_set_query` to `builtin_run`.
- Removes a conflicting int -> uint8_t conversion in `builtin_return`.
- Adds tests for the 3 remaining affected builtins.
- Simplifies the wording for the documentation for `set --query`.
- Does not change documentation for `functions --query`, because it does
not state the exit code in its API.
- Updates the CHANGELOG to reflect the change to all builtins.
builtin_set_query returns the number of missing variables. Because the
return value passed to the shell is an 8-bit unsigned integer, if the
number of missing variables is a multiple of 256, it would overflow to 0.
This commit saturates the return value at 255 if there are more than 255
missing variables.
This introduces a new variable $fish_color_keyword that will be used
to highlight keywords. If it's not defined, we fall back on
$fish_color_command as before.
An issue here is that most of our keywords have this weird duality of
also being builtins *if* executed without an argument or with
`--help`.
This means that e.g.
if
is highlighted as a command until you start typing
if t
and then it turns keyword.
E.g. autoloading and aliases are both about functions, variable scope
and overrides are both about variables.
It makes sense to group these together, and this might allow us to
collapse some of the TOC later.
Also move abbr explanation to interactive use (as abbrs are purely an
interactive concept)
(also add an example to tilde expansion, not making a separate commit
for that)
This goes to a separate file because that makes option parsing easier
and allows profiling both at the same time.
The "normal" profile now contains only the profile data of the actual
run, which is much more useful - you can now profile a function by
running
fish -C 'source /path/to/thing' --profile /tmp/thefunction.prof -c 'thefunction'
and won't need to filter out extraneous information.
This allows us to flex them together, so now you get one column on the
left with the title "Documents" and one on the right saying
"Sections" on narrow screens.
On wide screens it doesn't say "Table Of Contents" twice.
This should make it clearer
This used to put the TOC last, which is the last place you'd want it.
It's not perfect and we do some hacky layoutery to achieve it, but it
should generally be usable.
This makes the *tables* themselves scrollable, not the section div
they are in, which means the section doesn't scroll along with
them (it's already reflowed).
We should typically avoid scrolling even at max-width.
An exception here is the output of `functions` - this prints one very
long line, but it's really not important what's in there specifically,
it's just to illustrate the kind of output you'd get.
This clips overflowing padding/margins and thereby removes
non-"content" that's just off-screen, making the site scrollable.
The exception here is for tables - we allow scrolling the *section*
divs for those (because I have no idea how to only make the <table>
scrollable), if necessary of course.
This came up online - here we exclaim that fish has no aliases (which
is true), but then in the main docs we explain that you can use
`alias` to make something (which is also true).
Add a foot note explaining the apparent contradiction.
This removes the margin with the background gradient and such
completely once the screen falls under 700px. In those cases we really
don't want to waste space, and having just a weird blue bit above the
docs looks weirder than not having anything.
Currently binding `exit` to a key checks too late that it's exitted,
so it leaves the shell hanging around until the user does an execute
or similar.
As I understand it, the `exit` builtin is supposed to only exit the
current "thread" (once that actually becomes a thing), and the
bindings would probably run in a dedicated one, so the simplest
solution here is to just add an `exit` bind function.
Fixes#7604.
Prior to this change, `fish_private_mode` worked by just suppressing
history outright. With this change, `fish_private_mode` can be toggled on
and off. Commands entered while `fish_private_mode` is set are stored but
in memory only; they are not written to disk.
Fixes#7590Fixes#7589
It was always a bit ridiculous that argparse required `X-longflag` if
that "X" short flag was never actually used anywhere.
Since the short letter is for getopt's benefit, we can hack around
this with our old friend: Unicode Private Use Areas.
We have a counter, starting at 0xE000 and going to 0xF8FF, that counts
up for all options that don't have a short flag and provides one. This
gives us up to 6400 long-only options.
6.4K should be enough for everybody.
Prior to this change, a glob like `**/file.txt` would only match
`file.txt` in subdirectories; the `**` must match at least one directory.
This is historical behavior.
With this change we move a little closer to bash's implementation by
allowing a literal `**` segment to match in the current directory. That
is, `**/foo` will match both `foo` and `bar/foo`, while `b**/foo` will
only match `bar/foo`.
Fixes#7222.
And again clang-format does something I don't like:
- if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0) return found;
+ if (found != end && std::strncmp(found->name, name, len) == 0 && found->name[len] == 0)
+ return found;
I *know* this is a bit of a long line. I would still quite like having
no brace-less multi-line if *ever*. Either put the body on the same
line, or add braces.
