embedded-scripting-languages VS imapfilter

Hopefully the linked README provides a general overview (I know I need to write some more documentation!), but Steel is an implementation of the scheme programming language (not entirely compliant yet, but aiming for R5RS and R7RS compliance). It can be used as a standalone language via the interpreter/repl (like Python or Racket), or it can be embedded inside applications, like Lua. There are hundreds (thousands, probably) of embeddable languages, each with their own flavor - see a list compiled here for example https://github.com/dbohdan/embedded-scripting-languages

Use cases are generally for either configuration, scripting, or plugins - so scripting in games, or adding extensions to your text editor without having to use FFI or RPC + serializing a bunch of data. The advantage it has over using dynamic libraries (in general) is it runs in the same process, and can access the internal data structures directly without a lot of ceremony involved. The downside is typically is not as fast as native code unless a JIT is involved.

Javascript is an example of an embedded scripting, where the browser is the host application.

> There is a huge opportunity, IMO, for more players here.

There are quite a few embeddable scripting languages [1]. I think these days it's less common to embed a language mostly because there are good high-level languages that applications can be predominantly written in.

I'm not a huge fan of Lua but I think it is at least way more popular and better on every measure than TCL. There are plenty of other better less well-known options too: Rhai, Wren, AngelScript, Starlark (for some use cases), etc. There's a good list here.

or perhaps use one of this list (depending on who's writing the configuration): https://github.com/dbohdan/embedded-scripting-languages

Shouldn't be _too_ hard to convert your scripts.

I ran into the same problem and one workspace disallows App passwords. You can simply get the OAuth token with a little python script and then use it as the password: https://github.com/google/gmail-oauth2-tools/blob/master/pyt...

(see for example https://github.com/lefcha/imapfilter/issues/186)

My first real exposure to Lua was as the configuration language of imapfilter. Absolutely loved both.

Use [imapfilter](https://github.com/lefcha/imapfilter) to store the attachment in a local folder and delete/archive the mail. Then use something like [inotify](https://en.wikipedia.org/wiki/Inotify#:~:text=inotify%20(inode%20notify)%20is%20a,reports%20those%20changes%20to%20applications.)%20is%20a,reports%20those%20changes%20to%20applications.)) to run a script that sends the new pdf to the printer

Imapfilter runs lua scripts. Since it's basically just a lua interpreter with a pre-imported library, you can pretty much do any processing you might like, but... IMHO it doesn't seem great: the documentation is so-so, the API is a bit clunky and lacks basic functionality (eg. you have to decode utf8 mime headers yourself) and (personal opinion) writing an imapfilter script is not easier than using an IMAP library in whatever your favorite programming/scripting language might be.

You could look at something like imapfilter. It's designed to do what you want, I think, though I've never used it.

I know this one is an issue, and for that you will want to use an email client with the bridge. I have used a protonmail docker container shenxn/protonmail-bridge-docker with imapfilter to provide client side filtering.

If you can see yourself writing some scripts to clean it up, I can recommend imapfilter as a starting point. I learned enough Lua to be able to use this effectively. The "config" file is actually just a Lua script.

I believe that Google still offers IMAP access (I think you need to set up app passwords, or possibly jump through some OAUTH hoops), letting you use something like imapfilter to set up rules, connecting to Gmail, then doing the filtering.
