<![CDATA[Custom plumber in Emacs and sacc
================================

Emacs
-----

When a URL button is pressed, Emacs invokes the browse-url function, which
tipically triggers xdg-open on Linux systems. If you want to use a custom
plumber script instead:

;;;$DOOMDIR/config.el

(setq browse-url-browser-function 'browse-url-generic
browse-url-generic-program "plumb")

sacc
----

The following patch makes sacc fire *plumber right away on selecting type BIN
IMG or GIF:

<![CDATA[Little fix in sfeed_update
==========================

I use codemadness' sfeed as an RSS/Atom reader with its curses interface.
Noticed that new content for an entry with same id/title/link (e.g. edits
of a blog post after publishing) is not updated in feedfile when running
sfeed_update.

Issue: sort command inside merge() function.

diff --git a/sfeed_update b/sfeed_update

<![CDATA[Simple blogging
===============

Single bash script (inspired by codemadness `static-site-scripts`) to

* generate `gophermap`
* generate atom feed `feed.xml`
* #push content to gopherhole

Caveats
-------

* As usual, blogposts are represented by markdown files: these are supposed
to reside in the same directory of the script
* Filenames are supposed to be in the format `YYYY-MM-DD.md`

<![CDATA[Gopher(s) links in CIRCE
========================

* In Doom Emacs turn any regexp starting with `gophers://` into clickable
buttons:

;;; $DOOMDIR/config.el

(add-to-list 'thing-at-point-uri-schemes "gophers://")

* Add a desktop entry for sacc:

# /usr/share/applications/sacc.desktop

[Desktop Entry]
Version=1.0
Name=sacc
GenericName=Web Browser
Comment=Terminal gopher client
Keywords=Internet;Gopher;Browser;Web;Explorer
Exec=st -e /usr/bin/sacc %u
Terminal=false
Type=Application
MimeType=x-scheme-handler/gopher;x-scheme-handler/gophers;
Categories=Network;WebBrowser;

* If there are no other desktop entries for gopher clients, `xdg-open` should
now open gopher(s) links in sacc. If it doesn't, check the `mimeinfo.cache`
file or use `xdg-settings`.
