Just did an overhaul to reduce startup time. This uses use-package and a few other tricks. Also added support for editing Jupyter notebooks in GUI emacs. I don't do a lot with python or Jupyter notebooks, but when I do use the notebooks I don't want to be stuck in a web browser without code completion and keyboard shortcuts.

  • Switched from py-yapf to yapfify because py-yapf loses the kill ring when it runs and this was driving me crazy
  • Remove scroll bar, etc. even in -nw mode so that they are not present when connecting a GUI emacs-client to a daemon
  • Move configuration variables to front of file so it is much easier to configure the file.
  • Better checks for executables installed on the system so that ycmd, jupyter, and ripgrep are only used if actually installed. This helps portability of the file, which I've now successfully installed on several supercomputers.

  • Updated auctex configuration, adding sync support with Evince and fixing a bug with the package support libs not being loaded correctly from the byte-compiled file.

I have made several improvements to the .emacs.el file. In no particular order:

  • Fix the various incorrect warnings when compiling the file
  • Add IWYU .imp files to json mode
  • Add .tpp files to C++ mode
  • Add cmake-font-lock to get better highlighting of CMake files
  • Clean up EIN setup removing manually loading of packages and now check if a server is running before starting a new one
  • Add multiple-cursors package to allow editing multiple lines at once
  • Use string-inflection package to toggle between CamelCase, lowerCamelCase, snake_case, and SCREAMING_SNAKE_CASE
  • Improve ycmd-eldoc functionality
  • Add RealGUD for replacing the provided GUD.
  • Add origami-mode for code folding
  • Use edit-server to allow connecting to Emacs from, e.g. Chrome
  • Setup auto-updating of Emacs packages
  • Move Set packages to installsections closer to front of file

  • Added support for viewing LaTeX pdfs with Skim on macOS and Evince on Linux (Emacs OS detection is used to switch automatically)

Added:

  • Rainbow delimiters to make keeping track of which paren/brace/brackets go together easier
  • beacon-mode to flash the cursor when scrolling so it's easier to find
  • which-key to help you remember what key combination does what when you're in the middle of one
  • avy to quickly move around the current viewing area of the buffer (the keyboard shortcuts are currently set to be easy to use for Dvorak users, I'll add an option at the beginning of the file in the future)
  • zzz-to-char to replace zap-to-char for quickly deleting parts of the viewing area

Where can I find project-find-file? What package is it defined in?
