nix shell cli dump
my .zshrc was getting to be > 1,3 million lines on avg.
after days of configuration and variable tweaking
and then realizing that debugging was l'impossible so
tried bash-it (along w/ xonsh, which was v weird(?) tbd which i'll use)
tl;dr zsh feature Bloat, config hell
built-in-it! you don't even gotta go on github and organize by most stars
example bash-it browser opens a browser with the raw html displayed
shell echo "
#### bash-it autocompletion
another suspiciously seamless-ly integrated feature, w/ no
`compinit autoload -UZ)(R##F) -9; init` à la `.zshrc`
you select which autocompletions you'd like, w/ option for `all` and a warning
that it might slow things down, which, it didn't :~_)
#### bash-it search
```shell
bash-it search bundle

example:
11.3.1 Finding Duplicated Words in a Document A common error when writing large amounts of prose is to accidentally duplicate words. Typically you will see this in text as something like “the the program does the following…” When the text is online, often the duplicated words occur at the end of one line and the beginning of another, making them very difficult to spot.
This program, dupword.awk, scans through a file one line at a time and looks for adjacent occurrences of the same word. It also saves the last word on a line (in the variable prev) for comparison with the first word on the next line.
The first two statements make sure that the line is all lowercase, so that, for example, “The” and “the” compare equal to each other. The next statement replaces nonalphanumeric and nonwhitespace characters with spaces, so that punctuation does not affect the comparison either. The characters are replaced with spaces so that formatting controls don’t create nonsense words (e.g., the Texinfo ‘@code{NF}’ becomes ‘codeNF’ if punctuation is simply deleted). The record is then resplit into fields, yielding just the actual words on the line, and ensuring that there are no empty fields.
If there are no fields left after removing all the punctuation, the current record is skipped. Otherwise, the program loops through each word, comparing it to the previous one:
# dupword.awk --- find duplicate words in text
{
$0 = tolower($0)
gsub(/[^[:alnum:][:blank:]]/, " ");
$0 = $0 # re-split
if (NF == 0)
next
if ($1 == prev)
printf("%s:%d: duplicate %s\n",
FILENAME, FNR, $1)
for (i = 2; i <= NF; i++)
if ($i == $(i-1))
printf("%s:%d: duplicate %s\n",
FILENAME, FNR, $i)
prev = $NF
}
my first awk = an night cron job that emailed db stats in a beauty of a lil table:
sendEmail() {
local userCount="$(psql -d ${ConnString:?} -c $'\copy (select count(*) from users where created_at > now() - interval \'1 day\') to stdout' |
| awk '{print "<h1>signups</h1><p>there were " $0 " signups today</p>"
;}')"
}
tail /usr/local/var/postgres/server.log
// sample output:
FATAL: lock file "postmaster.pid" already exists
HINT: Is another postmaster (PID 90574) running in data directory "/usr/local/var/postgres"?

to see how krazi good it is, type /u/l/b<tab> which will complete to /usr/local/bin
on running brew update i noticed these caveats:
==> Upgrading zsh-completions
==> Downloading https://github.com/zsh-users/zsh-completions/archive/0.28.0.tar.gz
==> Downloading from https://codeload.github.com/zsh-users/zsh-completions/tar.gz/0.28.0
######################################################################## 100.0%
==> Caveats
To activate these completions, add the following to your .zshrc:
fpath=(/usr/local/share/zsh-completions $fpath)
You may also need to force rebuild `zcompdump`:
rm -f ~/.zcompdump; compinit
Additionally, if you receive "zsh compinit: insecure directories" warnings when attempting
to load these completions, you may need to run this:
chmod go-w '/usr/local/share'
i also see this a lot:
zsh completions have been installed to:
/usr/local/share/zsh/site-functions
zmodload zsh/complist
autoload -Uz compinit
compinit
and not a clue what it does, tho i know it's related to autocompl
also, when i cat .zcompdump i see:
autoload -Uz _brew _brew_cask _brew_services _carthage _cheat
ETC
_zsh _zsh-mime-handler _zsocket _zstyle _ztodo \
autoload -Uz +X _call_program

from the trouble shooting docs, re: permissions
"if you're unsure what to do, run
cd /usr/local \
sudo chown -R $(whoami) bin etc include lib sbin share var opt Cellar Caskroom Frameworks`
check for all plainfiles:
% l *(.)
PATH and path both set the search path for commands. These two variables are equivalent, except that one is a string and one is an array. If the user modifies PATH, the shell changes path as well, and vice versa.
% PATH=/bin:/usr/bin:/tmp:.
% echo $path
/bin /usr/bin /tmp .
% path=( /usr/bin . /usr/local/bin /usr/ucb )
% echo $PATH
/usr/bin:.:/usr/local/bin:/usr/ucb
from: http://zsh.sourceforge.net/Intro/intro_16.html#SEC16
to see which options can be set, do setopt <tab>
setopt autocd
now u can do
