Dev laptop setup: explicit automation Reinout van Rees http://reinout.vanrees.org 

Explicit is better than implicit •Don’t just fool around. •Collect everything. •“The cobbler’s children go barefoot.” •If it isn’t version controlled, it doesn’t exist. Or it isn’t explicit enough.

Dev laptop automation •Collect explicitly •Scripts, tools •Dotfiles •Version controlled •Backups 

What to collect? •Python tools •Handy shell scripts •Your custom tasks (so you finally make them) 

~/tools/bin •https://github.com/ reinout/tools •Shell+py scripts •Pip requirements file •Local development (zest.releaser, etc.) •... look on github 

Dev laptop automation •Collect explicitly •Scripts, tools •Dotfiles •Version controlled •Backups 

Dotfiles •On pypi. “pip install”(=> ~/tools/bin for me) •~/Dotfiles with files and directories •Symlinked into the root as dotfiles •Dotfiles command itself only manages it: great single-purpose script •Separate: ~/.emacs.d (=> starter kit) 

My ~/Dotfiles •New laptop? •Second home machine? •Your kid has a screwdriver? •All those nifty tricks... 

.inputrc # Ignore case for tab completion. set completion-ignore-case on # No need to press tab twice set show-all-if-ambiguous on # Type the start of a command ("svn" # or so) and press up/down to cycle # through previous versions of that # command. "\e[A": history-search-backward "\e[B": history-search-forward 

.profile # Handy aliases for going up in a directory. alias ..="cd .." alias ...="cd ../.." alias ....="cd ../../.." alias .....="cd ../../../.." 

.profile # No accidental shell closing with ctrl-d. export IGNOREEOF=1 # Two-line prompt export PS1="\u@\h:\w\n$ " # Exclude certain things from the # command history. export HISTIGNORE="&:l:vdir:[bf]g:exit"

Version control •Lots on github and bitbucket •But... dotfiles? Passwords? FTP accounts? •=> Private repository on own linux box •ssh://vanrees.org/~/git/Dotfiles •ssh://vanrees.org/hg/preken 

Checkoutmanager •Loads of git, bzr, hg, svn checkouts •31 git, 22 svn, 9 hg •No way I’m going to do “git pull” on every one of them in the morning! •=> checkoutmanager •commands: up, st, co, out •On pypi (and source on bitbucket)
