the_silver_searcher VS GNU Emacs

View on GitHub

If you have trouble finding it among the other stuff happening in the server log, well, so do I! I recommend learning how to programmatically search through your terminal output. Providing a universal method for this is challenging because various tools and terminal emulators implement this functionality differently. Another option would be to use tools like grep or the_silver_searcher (a favorite of mine) to search the file where your dev logs are written to. This file is located at log/development.log in a Rails project.

Some of the examples below use ag, but could just as well use grep or equivalent.

Why guess when [there are installation instructions for various platforms on the README](https://github.com/ggreer/the_silver_searcher#installing)?

Also, although it may not be easy to remember, is this really a problem in practice given the installation count in most contexts is one? If there's a context where it's installed regularly, that's a one-time addition to an install script, Dockerfile, etc. in my experience. Do you have a situation that isn't amenable to that?

The kernel changes a lot, so the books would get outdated quickly. But you can find simple / similar drivers, and read the code. Usually there are some documentation / comments on the headers before the function declarations. The Elixir and the Silver Searcher will help a lot.

My "vim" way of finding all the places where a function is being used: using visual mode, marking the function, and passing it to :Ag (silversearcher) The problem with this is that it is not 100% accurate, since it will just look for things with the same name, so I was thinking about using the LSP to make things more robust.

We're fans of ag, The Silver Searcher.

Helm-ag is an interface to the ag, silver-searcher, so check the docs for ag. For example, ag automatically ignore some files if there is a .gitignore with some file patterns, or you could use .agignore.

gnu.org - contains everything you need to research his philosophy.

stallman.org - personal website, contains a lot of opinion, but I absolutely respect this man in all what he says.

emacs.org (redirects to https://www.gnu.org/software/emacs/) - his non-philosophical work, one of two mainstream console text editors.

Forever, there was a file included in stock Emacs, `spook.el`, which could be hooked up to automatically add random strings of "interesting" keywords to each of your email or Usenet messages (in signatures, or in headers like `X-Spook`).

Looks like copyright date of 1988:

Try `M-x spook RET` in an Emacs buffer.

If you want to spare a couple of detours, you probably could start with Emacs Org-mode according to Greenspun's eleventh rule: "Any sufficiently complicated PIM or note-taking program contains an ad hoc, informally specified, bug-ridden, slow implementation of half of Org mode."

Emacs: winget install GNU.Emacs

The whole cl-lib thing is a total disaster:

https://github.com/emacs-mirror/emacs/blob/master/lisp/emacs...

They added cl- as a prefix to each Common Lisp symbol.

FIRST is now called cl-first, CAAAR is now cl-caaar .

I would really prefer if GNU Emacs removes all Common Lisp functionality, instead of creating this really wacky stuff, with discussions about this topic every year.

Never too late to try! Take your time. Emacs will outlive us all. https://www.gnu.org/software/emacs/

GNU Emacs is a versatile, open-source text editor that offers extensibility and customization—a sort of self-documenting real-time display editor. Our thanks for the suggestion go to CartanAnnullator.

Emacs

Their DEFUN and DEFVAR macros for example let us define a function or a variable that will be available as a Lisp function, and can be used as an ordinary C function from the C code. Emacs is written in pure C99 language and works with both GCC and Clang I believe. We can just define a C function via macro, and it is auto exported and made available to Lisp. For example my first patch to Emacs was for this function (we added "count" argument to make it possible to skip enumerating files in a directory for the case when user code is just interesting if a directory is empty or not):
