# This script updates the Oh My Zsh version of the zsh-history-substring-search
|
|
# plugin from the independent upstream repo. This is to be run by OMZ developers
|
|
# when they want to pull in new changes from upstream to OMZ. It is not run
|
|
# during normal use of the plugin.
|
|
#
|

# The official upstream repo is zsh-users/zsh-history-substring-search

# https://github.com/zsh-users/zsh-history-substring-search

# This is a zsh script, not a function. Call it with `zsh update-from-upstream.zsh`
|
|
# from the command line, running it from within the plugin directory.
|

#
|
|
# You can set the environment variable REPO_PATH to point it at an upstream
|
|
# repo you have already prepared. Otherwise, it will do a clean checkout of
|
|
# upstream's HEAD to a temporary local repo and use that.
|
|

# Just bail on any error so we don't have to do extra checking.

# This is a developer-use script, so terse output like that should

Oh My Zsh Distribution Notes

$thin_line
|
|
|
|
What you are looking at now is Oh My Zsh's repackaging of zsh-history-substring-search
|
|
as an OMZ module inside the Oh My Zsh distribution.
|
|
|
|
The upstream repo, $UPSTREAM_REPO, can be found on GitHub at
|
|
$upstream_github_url.
|
|
|
|
This downstream copy was last updated from the following upstream commit:
|
|
|
|
SHA: $upstream_sha
|
|
Commit date: $upstream_commit_date
|
|
|
|
Everything above this section is a copy of the original upstream's README, so things
|
|
may differ slightly when you're using this inside OMZ. In particular, you do not
|
|
need to set up key bindings for the up and down arrows yourself in \`~/.zshrc\`; the OMZ
|
|
plugin does that for you. You may still want to set up additional emacs- or vi-specific
|
|
bindings as mentioned above.
