From d86095145d42b1b9a3ef9cfa27949845483fca7b Mon Sep 17 00:00:00 2001 From: John D Pell Date: Mon, 18 Oct 2021 15:14:03 -0400 Subject: [PATCH] lib/helpers: first `shellcheck` pass MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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? Use `[[` for conditional evaluation. lib/helpers: fix `_command_exists()` The weird subshell is weird AF. Just do a normal `if`. Ditto `_binary_exists()`, `_completion_exists()`, and `_is_function()`! lib/helpers: second `shellcheck` pass lib/helpers: lint `_bash-it-migrate()` lib/helpers: lint `_disable-thing()` lib/helpers: lint `_enable-thing()` lib/helpers: lint `_help-list-aliases()` lib/helpers: lint `_help-plugins()` lib/helpers: some SC2034 fixes And SC2154 in `_make_reload_alias()` lib/helpers: lint `all_groups()` lib/helpers: `shfmt` My apologies to future `git blame` hunters ♥ lib/helpers: fix `all_groups()` - Don't write to disk, just pipe. - Don't loop, just do all functions. Performance of old implementation on my system: ``` real 0m9.996s user 0m5.318s sys 0m9.126s ``` Performance of new implementation on my system: ``` real 0m0.052s user 0m0.069s sys 0m0.025s ``` lib/helpers: cleanup - 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.) - remove `compgen` from `_bash-it-describe()` lib/helpers: fix `_bash-it-describe()` plugins/go: update tests Update tests for `plugins/go` to account for non-existing directories being ignored by `pathmunge()`. plugins/ruby: update tests Account for non-existing directory not added to path. plugins/ruby: tests on Mac OS X Test was failing only on Mac OS X for some reason, so refactor a little. lib/search: code style cleanup Couldn't even `shellcheck` until I did a first pass...too much noise! ♥ lib/search: `shellcheck` SC2076 SC2091 SC2004 SC2086 SC2207 lib/search: fix `_bash-it-flash-term()` 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. lib/search: fix SC2154 lib/search: adjust spacing on test assertions lib/search: `shfmt` My apologies to future `git blame` hunters ♥ lib/log: shellcheck lib/log: use builtin [[ for test evaluation lib/log: `shfmt` My apologies to future `git blame` hunters ♥ lib/log: short-circuit _has_colors() If we already looked up colors, and we already have them, then don't run `tput` again. main: Glob for *.bash properly when path contains spaces - `shfmt`, `shellcheck` - Clean up legacy/compatibility code to simpler control flow - Move theme stuff down to where themes are handled - Don't use `**` as _Bash It_ has never before set `globstar`; this eliminates varying behavior by environment; this alsö fixes users having any not-enabled themes under their custom dir. - Lose weird Mac-specific alternate shell startup file (Bash loads startup files on Mac the same as it does on any other *nix system.) reloader: `shellcheck` && `shfmt` Rewrite globbing per `shellcheck`'s SC2013 recommendations, and standardize whitespace. lib/preview: `shfmt` && `shellcheck` Fix theme file path globbing when $BASH_IT contains any spaces. My apologies to future `git blame` hunters ♥ lib/appearance: `shellcheck` && `shfmt` uninstall: `shellcheck` && `shfmt` lint: add lib to clean_files.txt Move `_set-prefix-based-on-path()` Instead of defining `_set-prefix-based-on-path()` in `scripts/reloader`, define it in `lib/utilities` so it can be helpful elsewhere too lib/utilities: XDG_CACHE_HOME Use $XDG_CACHE_HOME environment constant instead of placing a tmp/cache folder inside the bash-it data repo. If not defined, fall back to current behavior. plugins/dirs: use XDG_STATE_HOME Locate the bookmarks file in $XDG_STATE_HOME, and migrate an existing file from the old location if it exists. plugin/dirs: `shfmt` && `shellcheck` lib/theme: `shfmt` && `shellcheck` My apologies to future `git blame` hunters ♥ lib/colors: `shellcheck` && `shfmt` Alsö, clean up `__color_rgb` to just use a regular if block. lib/command_duration: `shfmt` && `shellcheck` My apologies to future `git blame` hunters ♥ lib/p4helpers: `shfmt` My apologies to future `git blame` hunters ♥ lib/githelpers: `shfmt` && `shellcheck` My apologies to future `git blame` hunters ♥ Add themes/*.bash to lint lib: move generic helper functions to helpers.bash `__check_precmd_conflict()`, `save_append_prompt_command()`, and `_save-and-reload-history()` are generally useful and not theme-specific. lib/helpers: add preexec functions Add matching `check_preexec_conflict()` with `check_precmd_conflict()` and alsö `safe_append_preexec()` lib/command_duration Remove use of temporary files. lib/command_duration: first pass at logging lib/command_duration: dynamic clock hand Calculate the position (from 1 to 12) of the hour hand on the clock emoji used for the _command_duration string. Expressly handle COMMAND_DURATION_COLOR as blank when undefined. lib/command_duration: Refactor using `$EPOCHREALTIME` Fallback to `$SECONDS` for older versions of _Bash_. Instead of shortcircuiting the definition, just short-circuit the function. This allows the variable to be set later, e.g. on theme change. plugin/cmd-returned-notify: Rewrite to match/use `lib/command_duration` Use `$EPOCHREALTIME` (or `$SECONDS`) built-in variable provided by Bash instead of `date +%s`. We're only measuing the difference in seconds, so avoid both the binary invocation as well as the subshell. Alsö, Reduce environmental pollution by not exporting every variable, and unsetting when done. Change variable names to match lib/command-duration Rename `preexec_return_notification()` to match lib/command-duration's `_command_duration_pre_exec()`, and guard against redefining it. This should now use the same preexec hook and variables as the theme library `command_duration`. tests: handle nanoseconds lib/command_duration: `shfmt` My apologies to future `git blame` hungers ♥ plugins/proxy: use `_command_exists` Addresses bash-it/bash-it#1632 Alsö, use `_log_notice`, quote variables, handle unbound parameters, &c. completions/sqlmap: use `_command_exists` Addresses bash-it/bash-it#1632 completion/fabric: no need for `_command_exists` If we're already inside the completion handler for `fab`...then it's a bit silly to check if `fab` is installed. plugins/java: quote path plugins/jekyll: simplify command flow Use bashisms, remove suplerfous variable, use parameter default value replacement plugins/latex: 2009 was 12 years ago Glob the currently installed edition, instead of transpoting us back to undergrad. plugins/osx-timemachine: code style cleanups Use bash functionality rather than external binaries, or even builtins. Alsö, if $SUDO_ASKPASS is set then pass -A to sudo. plugins/osx: code style improvements #TODO #TODO Avoid external binaries plugins/python: code style improvements Use shell functionality to avoid invoking external binaries, and quote some stuff. Alsö, use $EDITOR and related variables in order to fall through if some aren't defined. plugins/osx: unbound PROMPT_COMMAND Expressly handle undefined PROMPT_COMMAND as empty plugins/osx: dead code removal No need for gymnastics to determine if variable had been exported priort to modification. If it was, then it still is. See man bash(1). plugins/osx: unbound PROMPT_COMMAND I don't think this is possible given bash-preexec.sh dependency and early load. completion/system: accomodate multiple versions For Homebrew, switch between v1 and v2 of bash-completion based on whether the running Bash shell is new enough to use v2. plugins/go: simplify _bash-it-gopath-pathmunge() plugins/man: Add "R" to `$LESS` plugin/history: no need to set a trap Instead of globbally clearing `$HISTTIMEFORMAT` and setting a return trap to re-enable it, just make it local to the function. Also, set the defaults in a way that is happy with read-only parameters. plugin/latex: just call `pathmunge()` as it will check if the directory exists itself plugin/nginx: dont overwrite user-set variable, and quote path just in case plugin/git-subrepo: use `$HOME` instead of `~` If the outer variable is double-quoted, then the default expansion when undefined does not get tilde-expanded. Use `$HOME`. aliases/general: minor fixes - Don't define some aliases if the target isn't installed, use _command_exists to check instead of `type` and `which`. - Use `$EDITOR` for the editor for aliases about editing, excep the `sudo` ones because maybe you want those specifically? - Fix `ls` aliases to match their common definitions (-A instead of -a: don't show '.' and '..' when displaying hidden files). themes/base: use `type -P` instead of `which` Avoid external binary `which`. Use built-in `type -P` instead. Uppercase `-P` forces a path search to avoid hashed matches and functions/aliases and whatnot. plugins/git: use `type -p` completion/grunt: shellcheck completion/subversion: load system completion Load the completion script from the subversion package installed on the system, instead of bundling a copy. This addresses Bash-it/bash-it#1818. NOTE: If `completions/system` is enabled, then it will load this same file anyway automatically. plugins/battery: lint plugins/xterm: not just Xterm completion/system: load earlier than other completions plugin/projects: cleanup plugins/thefuck: lint plugins/todo: lint plugin/man: simplify Don't overwrite variables that the user has already set. completion/git: use `_completion_exists()` plugin/base: SC2144 globs literally don't work. At all. plugin/base: use `_bash-it-component-item-is-enabled()` lib/githelpers: `shfmt` && `shellcheck` My apologies to future `git blame` hunters ♥ lint: add lib and scripts to clean_files.txt and disable `shfmt` for now pending upstream mvdan/sh#721 Let function blocks begin on new lines so that the opennign and closing braces align. lib/helpers: new functions `_bash_it_history_auto_*()` 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. lib/helpers: new function `_find_uncle()` New function to do a search looking for a sibling to a parent of the current directory, for example to find `../../.git` to indicate that `$PWD` is inside a git repository. main: lint false positive style consistency improvements Adjust location of quotation marks in paths for visual consistency. Use double-bracket test evaluation, which has better feature support and avoids possible external tool invocation. Reduce environmental pollution Don’t `export` every single variable… Only variables that need to be seen by child processes need to be `export`ed. lib: avoid duplicate inclusion For lib/log and lib/utilities, add double-inclusion protection as we're so early in startup that these are loaded explicitly rather than through `reloader.sh` or even the early lib load loop. This *slightly* improves performance, but alsö improves debugging by reducing surface area. lint defaults and base No need for `cat` The input redirection can go at the beginning, it doens't need to go at the end. main: add some debugging alsö, clear a loop variable and set BASH_IT_LOG_PREFIX after reloader. main: move Jekyll stuff to plugins/jekyll If the user doesn't load the Jekyll plugin, then don't load any Jeykll stuff. lib/utilities: s/defined/loaded lib/helpers: define `pathmunge()` unconditionally plugins/history: Add `autoshare` to `$HISTCONTROL` lib/helpers: fix `_command_exists()` The weird subshell is weird AF. Just do a normal `if`. Ditto `_binary_exists()`. --- .editorconfig | 2 +- lib/utilities.bash | 7 +++++++ themes/githelpers.theme.bash | 0 3 files changed, 8 insertions(+), 1 deletion(-) mode change 100644 => 100755 themes/githelpers.theme.bash diff --git a/.editorconfig b/.editorconfig index eb3256aa29..36c98e6eaa 100755 --- a/.editorconfig +++ b/.editorconfig @@ -25,7 +25,7 @@ binary_next_line = true # like -bn switch_case_indent = true # like -ci space_redirects = true # like -sr keep_padding = false # like -kp -function_next_line = true # like -fn +#function_next_line = true # like -fn end_of_line = lf charset = utf-8 trim_trailing_whitespace = true diff --git a/lib/utilities.bash b/lib/utilities.bash index 9f9e6b6075..6804ab6f5f 100644 --- a/lib/utilities.bash +++ b/lib/utilities.bash @@ -33,6 +33,13 @@ function _bash-it-get-component-type-from-path() { echo "${filename}" } +function _set-prefix-based-on-path() { + filename=$(_bash-it-get-component-name-from-path "$1") + extension=$(_bash-it-get-component-type-from-path "$1") + # shellcheck disable=SC2034 # expected + BASH_IT_LOG_PREFIX="$extension: $filename" +} + # This function searches an array for an exact match against the term passed # as the first argument to the function.
