News came into my inbox yesterday that imzy is shutting down. Some people are moving to imzy @ Dreamwidth. I have mixed feelings about this because while I think Dreamwidth has a much better community model than tumblr or twitter, the interface is still the old livejournal template with crappy scaling to mobile.
But, I decided I might as well look at how to syndicate content from bigeekfan to my long-disused cbrachyrhynchos@dreamwidth page. It turns out that it's not that difficult since Dreamwidth supports posting by email with markdown support. So the process is:
- load my markdown files
- translate absolute paths to full urls
- pull the title from the YAML header
- separate the YAML header from the body
- send the email
Here's the code (identifying information removed).
#lang racket (require net/smtp) (require net/head) (require openssl) (define smtp-pass "") (define smtp-user "") (define smtp-server "") (define smtp-port 465) (define base-url "https://www.bigeekfan.com/") (define dreamwidth-address "email@example.com") ;; load the file into a string (define (load-file filename) (file->string filename)) ;;; create the email header using the recipient list ;;; and the subject (define (create-header recipient-list subject) (standard-message-header smtp-user recipient-list '() '() subject)) ;;; split the body into a list of lines (define (email-body html-string) (string-split html-string "\n")) ;;; send an email message to recipient-list with the subject ;;; and the body. (define (send-message recipient-list subject body-string) (smtp-send-message smtp-server smtp-user recipient-list (create-header recipient-list subject) (create-email-body body-string) #:port-no smtp-port #:auth-user smtp-user #:auth-passwd smtp-pass #:tcp-connect ssl-connect)) ;; clean up relative links (define (clean-relative-links string base-url) (string-replace string "](https://www.bigeekfan.com/" (string-join (list "](" base-url) ""))) ;; pull the title using regex (define (get-title string) (for/first ([line (string-split string "\n")] #:when (regexp-match? #rx"title:" line)) (second (regexp-match #rx"\"(.*)\"" line)))) ;; get the the position of the start of the body of the post (define (get-body-index string) (cdr (first (regexp-match-positions #rx"\n---\n\n" string)))) ;; get the body (define (get-body string) (substring string (get-body-index string))) ;;; combine all of the above functions to create an email body ;;; as a list of strings including the !markdown directive for ;;; dreamwidth. (define (create-email-body string) (append (list "!markdown" "") (email-body (get-body (clean-relative-links string base-url))))) ;;; send a hugo markdown file to recipient list (define (send-markdown-file recipient-list filename) (define text (load-file filename)) (define subject (get-title text)) (send-message recipient-list subject text)) ;;; command line argument parsing (define filename (make-parameter #f)) (when (< 0 (vector-length (current-command-line-arguments))) (filename (last (vector->list (current-command-line-arguments))))) ;;; if there's a command-line option, send the file. (if (filename) (send-markdown-file (list smtp-user dreamwidth-address) (filename)) (display "No file."))
This will probably need some modification to work with other markdown blogs. You'll want to use an app password if you're hard-coding the smtp password into the script.
