zimfw/environment

Sets generic Zsh built-in environment options.

environment

Sets sane Zsh built-in environment options.

Settings

If HISTFILE is not set, the history is set to be saved in ${ZDOTDIR:-${HOME}}/.zhistory. The file path can be customized with:

HISTFILE=/path/to/.zsh_history

Some Zsh installations already have a value set for HISTFILE. E.g. the /etc/zshrc file in macOS sets it to ${ZDOTDIR:-$HOME}/.zsh_history, so you'll have to set your own value in your ~/.zshrc if you want to customize it.

Zsh options

Changing directories

• AUTO_CD performs cd to a directory if the typed command is invalid, but is a directory.
• AUTO_PUSHD makes cd push the old directory to the directory stack.
• CD_SILENT does not print the working directory after a cd.
• PUSHD_IGNORE_DUPS does not push multiple copies of the same directory to the stack.
• PUSHD_SILENT does not print the directory stack after pushd or popd.
• PUSHD_TO_HOME has pushd without arguments act like pushd ${HOME}.

Expansion and globbing

• EXTENDED_GLOB treats #, ~, and ^ as patterns for filename globbing.

History

• HIST_FIND_NO_DUPS does not display duplicates when searching the history.
• HIST_IGNORE_DUPS does not enter immediate duplicates into the history.
• HIST_IGNORE_SPACE removes commands from the history that begin with a space.
• HIST_VERIFY doesn't execute the command directly upon history expansion.
• SHARE_HISTORY causes all terminals to share the same history 'session'.

Input/output

• INTERACTIVE_COMMENTS allows comments starting with # in the shell.
• NO_CLOBBER disallows > to overwrite existing files. Use >| or >! instead.

Job control

• LONG_LIST_JOBS lists jobs in verbose format by default.
• NO_BG_NICE prevents background jobs being given a lower priority.
• NO_CHECK_JOBS prevents status report of jobs on shell exit.
• NO_HUP prevents SIGHUP to jobs on shell exit.

environment's Issues

Changes to HISTSIZE and SAVEHIST caused those values to not be set anymore

Environment:

• zsh 5.8 (x86_64-ubuntu-linux-gnu)
• zim 1.4.3

@ericbn After the changes in 4293dd8, the following values are now exported in the environment:

$ echo $HISTSIZE $SAVEHIST
30 0

This is because the values are now only applied if variables don't currently have a value, but those two seem to always be set by Zsh. I tried starting a shell with zsh -f -il, and the same echo command returns the same two values.

Note: this seems to break the zsh-history-substring-search module, which is how I noticed something was wrong.

`.zim/modules/environment/init.zsh:setopt:16: no such option: CD_SILENT` when launching shell

• I've checked the existing issues and I'm not duplicating a report.
• I'm using the latest version of zimfw.
• I've checked the Changelog and I'm not being affected by documented changes.
• I've checked the 📢 Announcements and I'm not being affected by announced changes.
• I was able to reproduce the issue with a clean installation of Zim.
• I've pasted the output of zimfw info below.

Describe the bug
When launching a fresh instance of Zsh, I get the message in the title. It seems to be benign and does not appear until the shell is launched again. I get the message both on my daily use Zsh setup and following the repro example below, with no additional steps to the reproduce.

Steps to reproduce
The fist 4 steps restart the shell with a clean installation of Zim in a temporary directory.
Use exec zsh when restarting the terminal or restarting the shell is needed.

1. cd ${$(mktemp -d):A}
2. ZDOTDIR=${PWD} HOME=${PWD} ZIM_HOME=${PWD}/.zim exec zsh
3. curl -fsSL https://raw.githubusercontent.com/zimfw/install/master/install.zsh | zsh
4. exec zsh
5. The message should appear

Current behavior
.zim/modules/environment/init.zsh:setopt:16: no such option: CD_SILENT when launching a fresh instance of Zsh.

Expected behavior
No warning message.
