This is a follow-up from https://github.com/nushell/nushell/pull/8173,
which was merged shortly after the 0.76 release. That PR changed
`default_env.nu` so that the user's home folder is displayed as `~` in
the left prompt. It did so using `get -i`.
This PR just rewrites the Nu code from
https://github.com/nushell/nushell/pull/8173 to use `try`/`catch`
instead of `-i`, which will make it easier to remove the `-i` flags from
`get` and `select` eventually (see
https://github.com/nushell/nushell/pull/8379).
I would like to merge this before the 0.77 release, so we don't end up
with lots of `env.nu` files using `get -i` out in the wild.
# Description
This commit changes the `PROMPT_INDICATOR` and
`PROMPT_INDICATOR_VI_NORMAL` in the default_env and sample_login files.
It also changes its missing fallback in the prompt.rs file.
This has the intention of making the default prompt friendlier when
dealing with basic terminals that may not support displaying a huge
range of the Unicode standard, or users who don't want to get out of
their way to install custom fonts for their terminals. It's also
nicer/more balanced on the eyes, to me, and brings it in line with the
logo of nushell `nu>`.
# User-Facing Changes
New installations of nushell will have > as the default prompt
indicator, and running `config reset` will also change it. This might be
confusing for a few seconds, it could be minor enough that it just feels
slightly off. Anyone who has, for some reason, unset the
PROMPT_INDICATOR variable, or set it to $nothing, will also receive the
`>` treatment.
Users running on basic terminals (like cmd.exe on Windows 10) should no
longer face font issues with the default basic prompt.
# Drawbacks
The Unicode arrow is pretty cool. And it predates many of us. Maybe it's
worth keeping. One argument I could see, and mildly disagree with, is
that it might make users lean towards installing a modern font for their
terminal which will would have good consequences in the future.
* Initialize join.rs as a copy of collect.rs
* Evolve StrCollect into StrJoin
* Replace 'str collect' with 'str join' everywhere
git ls-files | lines | par-each { |it| sed -i 's,str collect,str join,g' $it }
* Deprecate 'str collect'
* Revert "Deprecate 'str collect'"
This reverts commit 959d14203e.
* Change `str collect` help message to say that it is deprecated
We cannot remove `str collect` currently (i.e. via
`nu_protocol::ShellError::DeprecatedCommand` since a prominent project
uses the API:
