Request to add tomelr package to GNU ELPA

[Kaushal Modi]

Hello,

I have been working on a small library very much inspired and reused from the core library json.el. 

The library is called tomelr, and it does just one job: convert the input lisp S-exp (alist or plist) to a TOML (see https://toml.io) config string. 

Purpose: I plan to replace a lot of custom logic for TOML generation in my ox-hugo package (Org mode to Markdown exporter for Hugo static site generator) with this dedicated and fully tested TOML generation library. 

The source code is at https://github.com/kaushalmodi/tomelr.

Companion blog post: https://scripter.co/defining-tomelr/

The README.org on the repo has a lot more details, but here's a short example of what this library does:

** Alist data

'((title . "Some Title") ;String

  (author . ("fn ln")) ;List

  (description . "some long description\nthat spans multiple\nlines") ;Multi-line string

  (date . 2022-03-14T01:49:00-04:00) ;RFC 3339 date format

  (tags . ("tag1" "tag2"))

  (draft . "false") ;Boolean

  (versions . ((emacs . "28.1.50") (org . "release_9.5-532-gf6813d"))) ;Map or TOML Table

  (org_logbook . (((timestamp . 2022-04-08T14:53:00-04:00) ;Array of maps or TOML Tables

                   (note . "This note addition prompt shows up on typing the `C-c C-z` binding.\nSee [org#Drawers](https://www.gnu.org/software/emacs/manual/html_mono/org.html#Drawers)."))

                  ((timestamp . 2018-09-06T11:45:00-04:00)

                   (note . "Another note **bold** _italics_."))

                  ((timestamp . 2018-09-06T11:37:00-04:00)

                   (note . "A note `mono`.")))))

** Plist data

'(:title "Some Title" ;String

  :author ("fn ln") ;List

  :description "some long description\nthat spans multiple\nlines" ;Multi-line string

  :date 2022-03-14T01:49:00-04:00 ;RFC 3339 date format

  :tags ("tag1" "tag2")

  :draft "false" ;Boolean

  :versions (:emacs "28.1.50" :org "release_9.5-532-gf6813d") ;Map or TOML Table

  :org_logbook ((:timestamp 2022-04-08T14:53:00-04:00 ;Array of maps or TOML Tables

                 :note "This note addition prompt shows up on typing the `C-c C-z` binding.\nSee [org#Drawers](https://www.gnu.org/software/emacs/manual/html_mono/org.html#Drawers).")

                (:timestamp 2018-09-06T11:45:00-04:00

                 :note "Another note **bold** _italics_.")

                (:timestamp 2018-09-06T11:37:00-04:00

                 :note "A note `mono`.")))

** TOML Output

You will get the below TOML output for either of the above input data.

title = "Some Title"

author = ["fn ln"]

description = """

some long description

that spans multiple

lines"""

date = 2022-03-14T01:49:00-04:00

tags = ["tag1", "tag2"]

draft = false

[versions]

  emacs = "28.1.50"

  org = "release_9.5-532-gf6813d"

[[org_logbook]]

  timestamp = 2022-04-08T14:53:00-04:00

  note = """

This note addition prompt shows up on typing the `C-c C-z` binding.

See [org#Drawers](https://www.gnu.org/software/emacs/manual/html_mono/org.html#Drawers)."""

[[org_logbook]]

  timestamp = 2018-09-06T11:45:00-04:00

  note = "Another note **bold** _italics_."

[[org_logbook]]

  timestamp = 2018-09-06T11:37:00-04:00

  note = "A note `mono`."

Thanks!
