I use emacs, and it is super powerful, but out of the box, it has some rough edges. Finding files in stock emacs isn’t great.<\/p>\n

I used to use a plugin called find-things-fast (https:\/\/github.com\/eglaysher\/find-things-fast<\/a>), but a previous employer had a codebase too big that made it grind to a halt. (Hint: different projects should be in different repos.) I grew out of the habit of using it, but when I upgraded and tried using it again, I got no results. Turns out the new version has a file extension whitelist, and the author sets it to his type of project, the Chromium project with lots of C++ file extensions. I wanted to use the file extensions for my projects, but rather than guess and make an ad-hoc list, I decided to roll up my command line sleeves and figure it out for real.<\/p>\n

Find all files in Git repo:<\/p>\n

git ls-files<\/pre>\n
Run a regex to strip out the ending file extension:<\/p>\n
git ls-files | perl -ne 'while(\/\\.[^\\.\\\/]+$\/g) {print \"$&\";}'<\/pre>\n
Sort the lines, and filter down to unique extensions:<\/p>\n
git ls-files | perl -ne 'while(\/\\.[^\\.\\\/]+$\/g) {print \"$&\";}' | sort | uniq<\/pre>\n
Append this to a file:<\/p>\n
git ls-files | perl -ne 'while(\/\\.[^\\.\\\/]+$\/g) {print \"$&\";}' | sort | uniq >> ~\/src\/file_extensions.txt<\/pre>\n
Run this command in each project.<\/p>\n
Create a sorted unique list from all projects:<\/p>\n
sort ~\/src\/file_extensions.txt | uniq > ~\/src\/sorted_file_extensions.txt<\/pre>\n
The I used an emacs editor macro to make an elisp list of wildcard strings, that looked like this:<\/p>\n
'(\"*.asd\" \"*.bash\" \"*.bowerrc\" \"*.clj\" \"*.cljs\" \"*.coffee\" \"*.conf\" \"*.css\" \"*.csv\" \"*.editorconfig\" \"*.el\" \"*.eot\" \"*.erb\" \"*.example\" \"*.gif\" \"*.gitattributes\" \"*.gitconfig\" \"*.gitignore\" \"*.gitkeep\" \"*.gitmodules\" \"*.goo\" \"*.haml\" \"*.htm\" \"*.html\" \"*.info\" \"*.irbrc\" \"*.jade\" \"*.jpg\" \"*.js\" \"*.jshintrc\" \"*.json\" \"*.k\" \"*.lisp\" \"*.lock\" \"*.lua\" \"*.md\" \"*.nrepl-port\" \"*.nvmrc\" \"*.orig\" \"*.png\" \"*.rake\" \"*.rb\" \"*.rdoc\" \"*.rspec\" \"*.ru\" \"*.ruby-gemset\" \"*.ruby-version\" \"*.scm\" \"*.scss\" \"*.sh\" \"*.sml\" \"*.ss\" \"*.swf\" \"*.texi\" \"*.text\" \"*.ttf\" \"*.txt\" \"*.woff\" \"*.xml\" \"*.yml\" \"*.zsh\")<\/pre>\n
I customized the variable ftf-filetypes, restarted emacs, and now if works like a dream again. Thanks Elliot<\/a>!<\/p>\n","protected":false},"excerpt":{"rendered":"
