When the file is being re-created, we write to it, instead of appending to
it. So, the rm here is unnecessary and prevents users from linking the profile
file to another location that is potentially under version control. For
instance, once could link to a profile file located at
"$BASH_IT_CUSTOM/profiles/*.bash_it".
Two new functions `_bash-it-history-auto-save()` and `_bash-it-history-auto-load()`, which append new history to disk and load new history from disk, respectively.
See bash-it/bash-it#1595 for discussion.
This allows future use like `bash-it preview`. Alsö, allows to use `$BASH_PREVIEW` to specify a particular theme to preview instead of just doing all of them.
Improve `_bash-it-erase-term()`, `_bash-it-flash-term()`, `_bash-it-rewind()`, `_bash-it-search-result()`, and `_bash-it-search-component()`. Minor tweaks to `_bash-it-is-partial-match()`, and `_bash-it-search()`.
1. `$text_black` isn't a parameter provided by _Bash It_. Typo?
2. `$bold_yellow` is meant for prompt strings and putputs `\[`; ditto `$bold_red`.
3. The color was never returned to normal after.
This reverts bash-it/bash-it#99, a metaprogramming adventure in terminal color code escape computation. It was functionally reverted in bash-it/bash-it#699; I'm just finishing the job.
Bash loads initialization files on Mac just the same as it does on Linux or WSL. Our previous assumptions were wrong, and my fix was alsö wrong because I made more assumptions!
This patch eliminates the assumptions. Literally just load either the startup file the shell started with, or fall back to `~/.bashrc`. Don't check `shopt -q login_shell` and don't check `$OSTYPE` or anything else.
Define the helper functions for `bash-preexec.sh` immediately after importing it, rather than in `lib/theme`.
- `__check_precmd_conflict()` and `save_append_prompt_command()` are generally useful and not theme-specific.
- Add matching `__check_preexec_conflict()` and `safe_append_preexec()`.
Quote some parameter uses that don't strictly require it, but since Bash needs so many quotes everywhere else my brain worms feel better when these are quoted too.
lib/helpers: simplify some quote escapes
Replace weird non-globs with array and loop, as suggested by `shellcheck`. Alsö, simplify several constructs to eliminate external binaries.
Alsö, see mvdan/sh issue 558
lib/helpers: unbound positional parameters
- Improve `pushd`/`popd` somewhat
- local some parameters
- Lose weird Mac-specific alternate shell startup file (Bash loads startup files on Mac the same as it does on any other *nix system.)
Quote things, SC2268, SC2143, SC2181, SC2162, SC2016, SC2013, &c.
Rewrite globbing per `shellcheck`’s SC2013, and alsö s/typeset/local/g. Eliminate `compgen` where possible.
Alsö: use the existing utility functions `_bash-it-get-component-type-from-path` and `_bash-it-get-component-name-from-path`, which just use parameter substitution anyway. Why was `sed` here?
Alsö, don't add not-existing directories to `$PATH` in `pathmunge()`.
Finally, merge PR #1865 from NoahGorny...and clean it a bit...
- Don't write to disk, just pipe.
- Don't loop, just do all functions.

Don't use `local -n var` so that we can support v3.2...
Note: function names and variable names are different namespaces, so we can have a variable named the same as the function...which makes it really easy to predict default names for results when returning this way.
...to replace `_set-prefix-based-on-path()` in `scripts/reloader`.
Deliberately does not use `_bash-it-get-component-name-from-path()`/`_bash-it-get-component-type-from-path()` as we need some of the intermediate state and would have to reimplement anyway.
Alsö, fix tests to load `lib/colors` instead of `lib/appearance`...wut
Alsö, `short-circuit _has_colors()`: If we already looked up colors, and we already have them, then don't run `tput` again.
My apologies to future `git blame` hunters ♥
The existing function `_bash-it-grep()` is weird. New function `_bash-it-egrep()` just does the thing without requiring two subshells and manual invocation.
