* fish_key_reader: Simplify default output
It now only prints the bind statement. Timing information and such is
relegated to a separate "verbose" mode.
* Adjust fish_key_reader docs
* Adjust tests
This introduces a new variable, $fish_color_option, that can be used
to highlight options differently.
Options are tokens starting with `-`, but only up to (and including!)
the first `--`.
Fixes#8292.
First, I changed "the escape key" to :kbd:`Esc`. This makes this information
easier to find when scanning the docs because it stands out and because it is
more consistent with the docs's formatting of keyboard keys.
Additionally, emphasize that escape/page-down can be used to edit
the original search sting.
Finally, I added a link from the FAQ to history-search to make this mechanism
easier to discover.
This was all to address confusion in former zsh and bash users as to how to
edit a search that is in progress, but this will also help new users. See
https://github.com/fish-shell/fish-shell/pull/6686#issuecomment-872960760
This spoke of "--bold" and "-b", which are two different things - "-b"
is short for "--background", bold is "-o".
Instead let's just mention the long versions of all the switches.
See #8053.
A bunch of our variables are only relevant for interactive use, but
this is two whole sections on them. Simply move them inside "Syntax
highlighting" and leave the link in Special Variables.
The file is called "config.fish", not "init.fish". We'll call it
"configuration" now.
"Initialization" might be slightly more precise, but in an irritating
way.
Also some wording improvements to the section. In particular we now
mention config.fish *early*, before the whole shebang.
fish_private_mode is active if set to something non-empty, but the docs
suggested checking if it is set at all. Switch the docs to match the
implementation through `test -n "$fish_private_mode"`
Fixes#8001
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.
