I’ve given myself permission to spend an hour or two tickling my brain with various technical ideas and prototypes every day. This means Emacs geekery is going to turn up on my blog more often. =) Here’s a recent hack that I put together to make my weekly reviews a little easier.
I skim a lot of blog posts on my phone using the Feedly app. (See: How to read blogs efficiently with a feed reader.) I save the posts I want to follow up on or include in my weekly round-up. I have an If This Then That recipe that monitors my saved items and stashes them in Evernote with the
roundup tag. If I come across other interesting pages while browsing on my computer, I use the Evernote Web Clipper to save those pages with the
roundup tag as well.
In the past, I selected a range of notes to export from Evernote, saved them to a file, and used my sacha/evernote-extract-links-for-review function to extract the titles and URLs. I opened each of the pages with C-c C-o (
org-open-at-point) to refresh my memory and follow up. I deleted lines that were no longer relevant. Since IFTTT had changed to rewriting the URLs instead of leaving the source URLs alone, I copied the original URLs and replaced the links that were in Org.
This is Emacs, though, and even that can be smoothened with a little scripting. Now I can use the code below to expand URLs and to open all the URLs in the region.
Link-related convenience functions
I picked this up from http://www.emacswiki.org/emacs/AlexSchroederConfigOrientalibombus .
(defun kensanata/resolve-redirect (url) "Resolve shortened URL by launching `curl --head' and parsing the result." (let* ((curl (shell-command-to-string (format "curl --silent --head %s" url))) (location (when (and (string-match "\\`HTTP/1\.1 301" curl) (string-match "^Location: \\(.*\\)" curl)) (match-string 1 curl)))) (or location url))) (defun sacha/resolve-urls-in-region (beg end) "Expand URLs between BEG and END." (interactive "r") (save-excursion (save-restriction (narrow-to-region beg end) (goto-char (point-min)) (while (re-search-forward org-bracket-link-regexp nil t) (replace-match (save-match-data (kensanata/resolve-redirect (match-string 1))) t t nil 1)) (goto-char (point-min)) (while (re-search-forward org-link-re-with-space nil t) (replace-match (save-match-data (kensanata/resolve-redirect (match-string 0))) t t nil))))) (defun sacha/open-urls-in-region (beg end) "Open URLs between BEG and END." (interactive "r") (save-excursion (save-restriction (narrow-to-region beg end) (goto-char (point-min)) (while (re-search-forward org-plain-link-re nil t) (org-open-at-point)))))
Evernote on Windows doesn’t have the same kind of scripting capabilities that Evernote on the Mac has, but it turns out you can still do a fair bit of scripting with the
(defun sacha/evernote-export-and-extract (start-date end-date) "Extract notes created on or after START-DATE and before END-DATE." (let ((filename "c:/sacha/tmp/Evernote.enex")) (call-process "c:/Program Files (x86)/Evernote/Evernote/enscript.exe" nil t t "exportNotes" "/q" (concat " tag:roundup" " created:" (replace-regexp-in-string "-" "" start-date) " -created:" (replace-regexp-in-string "-" "" end-date)) "/f" filename) (sacha/evernote-extract-links-for-review filename))) (defun sacha/evernote-extract-links-for-review (filename) "Extract note names and URLs from FILENAME. The file should be an ENEX export." (interactive (list (read-file-name "File: ") (org-read-date) (org-read-date))) (let (list) (with-temp-buffer (insert-file-contents filename) (goto-char (point-min)) (while (re-search-forward "<title>\\(.+?\\)</title>\\(.*?\n\\)*?.*?href=\"\\(.*?\\)\"" nil t) (setq list (cons (cons (match-string-no-properties 1) (match-string-no-properties 3)) list)))) (setq list (mapconcat (lambda (x) (concat "- [[" (kensanata/resolve-redirect (cdr x)) "][" (car x) "]]: ")) list "\n")) (if (called-interactively-p 'any) (insert list) list)))
Let’s see how this new workflow goes. =) If you’re curious, you can check out the rest of my weekly-review-related code in my Emacs configuration.
