what makes a good tool good? long list of items feedback is the one he likes the most, the core of agility

Tools

Getting around

you end up doing cd tab, tab, tab

Z - jump around

• {ba,z}sh: https://github.com/rupa/z
• fish: https://github.com/jethrokuan/z
• 100% shell script
• frequency
• use instead of cd
  • need to use it once so it can learn
  • has tab completion
  • stores files in .local/share/z/data
  • db format: dir | number of times | ...

Finding stuff

new shiny tools instead of find, grep and locate.

fzf - fuzzy find

• https://github.com/junegunn/fzf
• Golang
• fuzzy, not regex
• smart case
• can be used like:
  • find to find files
  • grep to search within files
  • decision to make a decision like what branch to checkout

For example, dmesg dumps everything; dmesg | fzf. Then type error and it finds all the error in different formats. It also find "allocatE ResouRce fOR EISA"

• fzf emits to stdout

• gc script he wrote for git checkout using fzf to figure out what branch to checkout

• fzf can be used to search history

fd - find

• https://github.com/sharkdp/fd
• Rust
• use instead of find
• heuristics
  • skip hidden files by default
  • skip ignored files by default
  • smartcase
• even without heuristics, 9 times faster than find
  • it can read .gitignore and other source control types and ignores those as well

ripgrep = grep, but better

• https://github.com/BurntSushi/ripgrep
• Rust
• use instead of grep
• heuristics:
  • recursive file search by default
  • skip hidden files by default
  • skip ignored files by default
• you can output json if you want as well

Example: rg uinput vs grep -r uinput SLOW

• rged const (rged is a script that uses rg and fzf)

gron - make json greppable

• https://github.com/tomnomnom/gron
• gron converts the json into equivalent javascript
• combines really well with yaml2json and json2yaml

Looking at things

exa - ls for humans

• https://github.com/ogham/exa
• Rust
• alias to ls
• color coded permissions, understands git, also replaces tree
• -h instead of human readable gives you headers

bat - cat with wings

• https://github.com/sharkdp/bat
• rust

hexyl = read the matrix

• https://github.com/sharkdp/hexyl
• similar to xxd but color coded

fixing ux

detox

• detox.sourceforge.net
• c
• inline form of it too (inline-detox) uses stdin and renames on the fly

fish

• https://github.com/fish-shel/fish-shell
• C++
• fish_update_completions
• funced and funcsave
• location-sensitive completion
• can parse your man pages and create completions for them
• can tell you if no executable exists

entr - run commands when files change

• http://eradman.com/entrproject/

Multitasking

tmux

• https://github.com/tmux/tmux

Editing

kakoune

• https://github.com/mawww/kakoune
• C++
• vi-like, but constant feedback
