How can I make org-protocol work on Openbox? - firefox

I tried the instructions - I am using Firefox on Lubuntu (Openbox). But I get the error
"Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program".
How should I fix this?

The following steps for setting up org-protocol work with Ubuntu 16.04 (Xenial Xerus) and presumably later versions. Org-mode is assumed to have already been set-up (and installed using apt-get install org-mode or via the ELPA repository).
Set-up
Add .desktop file
Create and save a file called org-protocol.desktop to ~/.local/share/applications containing:
[Desktop Entry]
Name=org-protocol
Exec=emacsclient %u
Type=Application
Terminal=false
Categories=System;
MimeType=x-scheme-handler/org-protocol;
Then run:
$ update-desktop-database ~/.local/share/applications/
This step makes Firefox aware that "org-protocol" is a valid scheme-handler or protocol (by updating ~/.local/share/applications/mimeinfo.cache), and causes Firefox to prompt for a program to use when opening these kinds of links.
Add config settings to ~/.emacs.d/init.el (or ~/.emacs) file
Have the following settings in your Emacs configuration file:
(server-start)
(require 'org-protocol)
Also add some template definitions to the configuration file, for example:
(setq org-protocol-default-template-key "l")
(setq org-capture-templates
'(("t" "Todo" entry (file+headline "/path/to/notes.org" "Tasks")
"* TODO %?\n %i\n %a")
("l" "Link" entry (file+olp "/path/to/notes.org" "Web Links")
"* %a\n %?\n %i")
("j" "Journal" entry (file+datetree "/path/to/journal.org")
"* %?\nEntered on %U\n %i\n %a")))
Now run Emacs.
Create your notes.org file
Assuming you use the capture templates defined in step 2, you will need to prepare a notes.org file at the location you specified in step 2. You must create this file -- if it is not created along with the headlines specified in step 2, org-mode will just give a warning when you try to capture web-pages. So, given the capture templates from step 2, notes.org should contain the following:
* Tasks
* Web Links
Add bookmarklet(s) to Firefox
Save bookmark to toolbar containing something like the following as the location:
javascript:location.href='org-protocol://capture?template=l&url='+encodeURIComponent(location.href)+'&title='+encodeURIComponent(document.title)+'&body='+encodeURIComponent(window.getSelection())
If you are using an older version of org-mode, you may need to use the following instead:
javascript:location.href='org-protocol://capture://l/'+encodeURIComponent(location.href)+'/'+encodeURIComponent(document.title)+'/'+encodeURIComponent(window.getSelection())
Notice the 'l' (lowercase L) in the above URL -- this is what chooses the capture template (automatically) -- it is the key one would normally have to press when capturing with org-mode via C-c c.
When you click on this bookmarklet, Firefox will ask what program to use to handle the "org-protocol" protocol. You can simply choose the default program that appears ("org-protocol").
Using it
(Optionally) select some text on a webpage you're viewing in Firefox. When you click on the bookmarklet, the link and selected text will be placed in the Emacs capture buffer. Go to Emacs, modify the capture buffer as desired, and press C-c C-c to save it.

Add protocol handler
Create file ~/.local/share/applications/org-protocol.desktop containing:
[Desktop Entry]
Name=org-protocol
Exec=emacsclient %u
Type=Application
Terminal=false
Categories=System;
MimeType=x-scheme-handler/org-protocol;
Note: Each line's key must be capitalized exactly as displayed, or it will be an invalid .desktop file.
Then update ~/.local/share/applications/mimeinfo.cache by running:
On GNOME:
update-desktop-database ~/.local/share/applications/
On KDE:
kbuildsycoca4
Configure Emacs
Init file
Add to your Emacs init file:
(server-start)
(require 'org-protocol)
Capture template
You'll probably want to add a capture template something like this:
("w" "Web site"
entry
(file+olp "/path/to/inbox.org" "Web")
"* %c :website:\n%U %?%:initial")
Note: Using %:initial instead of %i seems to handle multi-line content better.
This will result in a capture like this:
\* [[http://orgmode.org/worg/org-contrib/org-protocol.html][org-protocol.el – Intercept calls from emacsclient to trigger custom actions]] :website:
[2015-09-29 Tue 11:09] About org-protocol.el
org-protocol.el is based on code and ideas from org-annotation-helper.el and org-browser-url.el.
Configure Firefox
Expose protocol-handler
On some versions of Firefox, it may be necessary to add this setting. You may skip this step and come back to it if you get an error saying that Firefox doesn't know how to handle org-protocol links.
Open about:config and create a new boolean value named network.protocol-handler.expose.org-protocol and set it to true.
Note: If you do skip this step, and you do encounter the error, Firefox may replace all open tabs in the window with the error message, making it difficult or impossible to recover those tabs. It's best to use a new window with a throwaway tab to test this setup until you know it's working.
Make bookmarklet
Make a bookmarklet with the location:
javascript:location.href='org-protocol://capture://w/'+encodeURIComponent(location.href)+'/'+encodeURIComponent(document.title)+'/'+encodeURIComponent(window.getSelection())
Note: The w in the URL chooses the corresponding capture template. You can leave it out if you want to be prompted for the template.
When you click on this bookmarklet for the first time, Firefox will ask what program to use to handle the org-protocol protocol. If you are using Ubuntu 12.04 (Precise Pangolin), you must add the /usr/bin/emacsclient program, and choose it. With Ubuntu 12.10 (Quantal Quetzal) or later, you can simply choose the default program that appears (org-protocol).
You can select text in the page when you capture and it will be copied into the template, or you can just capture the page title and URL.
Tridactyl
If you're using Tridactyl, you can map key sequences something like this:
bind cc js location.href='org-protocol://capture://w/'+encodeURIComponent(content.location.href)+'/'+encodeURIComponent(content.document.title)+'/'+encodeURIComponent(content.document.getSelection())
You might also want to add one for the `store-link` sub-protocol, like:
bind cl js location.href='org-protocol://store-link://'+encodeURIComponent(content.location.href)+'/'+encodeURIComponent(content.document.title)
Capture script
You may want to use this script to capture input from a terminal, either as an argument or piped in:
#!/bin/bash
if [[ $# ]]
then
data="$#"
else
data=$(cat)
fi
if [[ -z $data ]]
then
exit 1
fi
encoded=$(python -c "import sys, urllib; print urllib.quote(' '.join(sys.argv[1:]), safe='')" "${data[#]}")
# "link" and "title" are not used, but seem to be necessary to get
# $encoded to be captured
emacsclient "org-protocol://capture://link/title/$encoded"
Then you can capture input from the shell like this:
tail /var/log/syslog | org-capture
org-capture "I can capture from a terminal!"
These instructions are more up-to-date than the ones in Mark's answer.

Neomutt Pipe Attachments to Shell Program from Menu

The header of the attachments menu in neomutt gives the options
q:Exit s:Save |:Pipe p:Print ?:Help
I assumed that the Pipe option would allow me to pipe a chosen attachment to the shell. In particular, maybe I want to open a file in a way that bypasses the mailcap defaults.
Suppose I wanted to open a file from the attachment menu with open. Is there a way to achieve this with Pipe and not by going to edit my mailcap?
Thanks
The only downfall of this is you need to specify all types, because wildcard can be only in subtype - */* or * doesn't work
Store original mailcap file location in a variable
Define macro in attach menu that changes mailcap file to a new one, run view-attach (which uses open to open a file with) and return to original mailcap_path configuration.
~/.muttrc
set my_origmailcap=$mailcap_path
macro attach <Space> "\
<enter-command>set mailcap_path=~/.mailcap2<enter>\
<view-attach>\
<enter-command>set mailcap_path=$my_origmailcap<enter>\

using ag in emacs under macos

I use project-root to setup root directory of the project as:
(setq project-roots
`(("Git Project"
:root-contains-files (".gitignore"))))
Then I go into my git project directory (e.g ~/.emacs.d), and press M-x ag-project-files and enter some search string. It shows the files which contains the string. But when I push enter key on top of the file (in order to jump into that file), it shows error message like:
Find this error in (default File: lisp/ag.el): ~/.emacs.d/
I don't know how this error come out? It is all right when I use emacs in Linux, but no good in Mac. Have you ever met this problem?
I ran into this same problem using projectile-ag. It turned out that setting the "--nogroup" parameter for ag was causing this break (but only on macOS). To work around this I just set ag-arguments to not include the "--nogroup" param:
(setq ag-arguments (list "--smart-case" "--column"))

How to (easily) get current file path in Sublime Text 3

How to (easily) get current file path in Sublime Text 3
I don't often use ST console (I used it only once to install package manager), but I suppose it could be good way to :
get current file path like some kind pwd command.
But it doesn't work.
Does anyone know an easy way to get current file path?
to clipboard : better not a strict objective in the answer
not necessary by ST command, maybe package?
Right click somewhere in the file (not on the title tab) --> Copy file path
If you don't want to use the mouse, you could set up a keyboard shortcut as explained here https://superuser.com/questions/636057/how-to-set-shortcut-for-copy-file-path-in-sublime-text-3
To easily copy the current file path, add the following to Key Bindings - User:
{ "keys": ["ctrl+alt+c"], "command": "copy_path" },
Source
Key Bindings - User can be opened via the command palette (command + p on OSX)
Easy to understand using image. On Right Click you will get this.
Transcribed code in image for convenience:
import sublime, sublime_plugin, os
class CopyFilenameCommand(sublime_plugin.TextCommand):
def run(self, edit):
if len(self.view.file_name()) > 0:
filename = os.path.split(self.view.file_name())[1]
sublime.set_clipboard(filename)
sublime.status_message("Copied file name: %s" % filename)
def is_enabled(self):
return self.view.file_name()... # can't see
Mac OS X - Sublime Text 3
Right click > Copy File Path
A lot of these answers involve touching the mouse. Here's how to do get the path without any mouse clicks using SideBarEnhancements
Install SideBarEnhancements using PackageControl.
Click super + shift + P to open the command palette
In the command palette begin typing path until you see File: Copy Path
Select File: Copy Path
Now the path to file you are working in is copied into your clipboard.
There is a Sublime Package which gives your current file location inside a status bar. I just cloned them directly to my /sublime-text-3/Packages folder.
git clone git#github.com:shagabutdinov/sublime-shell-status.git ShellStatus;
git clone git#github.com:shagabutdinov/sublime-status-message.git StatusMessage;
You have to check/read the description on GitHub. Even it is listed in package control it would not install properly for me. You can actually edit the shell output as you want. If you have the right skills with python/shell.
Looks like this (Material Theme)
If you're like me and always click on items in the sidebar just to realize that copying the path only works when clicking in the editor area, have a look at the SideBarEnhancements package. It has a huge bunch of options to copy file paths in a variety of different ways.
Installation is available via Package Control (despite the webpage only mentions installation via manual download).
Note: The package “sends basic, anonymous statistics”. The webpage explains how to opt out from that.
Go to this link. The code in the link is given by robertcollier4.
Create a file named CpoyFileName.py or whatever you like with .py extension.
Save the file in Sublime Text 3\Packages\User folder. Then paste the above given key bindings in your Preferences: Key Bindings file.
Now, you can use the specified key bindings to copy just filename or total (absolute) filepath.
Please note that the filename or filepath do contain file extension.
Fastest Solution ( No Packages Needed + Comprehensive ):
Folder Path:
Folder in "Sidebar"
Right Click
"Find In Folder"
"Where" field contains everything you need
File Path:
File in current "Tab"

Programming a Filter/Backend to 'Print to PDF' with CUPS from any Mac OS X application

Okay so here is what I want to do. I want to add a print option that prints whatever the user's document is to a PDF and adds some headers before sending it off to a device.
I guess my questions are: how do I add a virtual "printer" driver for the user that will launch the application I've been developing that will make the PDF (or make the PDF and launch my application with references to the newly generated PDF)? How do I interface with CUPS to generate the PDF? I'm not sure I'm being clear, so let me know if more information would be helpful.
I've worked through this printing with CUPS tutorial and seem to get everything set up okay, but the file never seems to appear in the appropriate temporary location. And if anyone is looking for a user-end PDF-printer, this cups-pdf-for-mac-os-x is one that works through the installer, however I have the same issue of no file appearing in the indicated directory when I download the source and follow the instructions in the readme. If anyone can get either of these to work on a mac through the terminal, please let me know step-by-step how you did it.
The way to go is this:
Set up a print queue with any driver you like. But I recommend to use a PostScript driver/PPD. (A PostScript PPD is one which does not contain any *cupsFilter: ... line.):
Initially, use the (educational) CUPS backend named 2dir. That one can be copied from this website: KDE Printing Developer Tools Wiki. Make sure when copying that you get the line endings right (Unix-like).
Commandline to set up the initial queue:
lpadmin \
-p pdfqueue \
-v 2dir:/tmp/pdfqueue \
-E \
-P /path/to/postscript-printer.ppd
The 2dir backend now will write all output to directory /tmp/pdfqueue/ and it will use a uniq name for each job. Each result should for now be a PostScript file. (with none of the modifications you want yet).
Locate the PPD used by this queue in /etc/cups/ppd/ (its name should be pdfqueue.ppd).
Add the following line (best, near the top of the PPD):
*cupsFilter: "application/pdf 0 -" (Make sure the *cupsFilter starts at the very beginning of the line.) This line tells cupsd to auto-setup a filtering chain that produces PDF and then call the last filter named '-' before it sends the file via a backend to a printer. That '-' filter is a special one: it does nothing, it is a passthrough filter.
Re-start the CUPS scheduler:sudo launchctl unload /System/Library/LaunchDaemons/org.cups.cupsd.plist
sudo launchctl load /System/Library/LaunchDaemons/org.cups.cupsd.plist
From now on your pdfqueue will cause each job printed to it to end up as PDF in /tmp/pdfqueue/*.pdf.
Study the 2dir backend script. It's simple Bash, and reasonably well commented.
Modify the 2dir in a way that adds your desired modifications to your PDF before saving on the result in /tmp/pdfqueue/*.pdf...
Update: Looks like I forgot 2 quotes in my originally prescribed *cupsFilter: ... line above. Sorry!
I really wish I could accept two answers because I don't think I could have done this without all of #Kurt Pfeifle 's help for Mac specifics and just understanding printer drivers and locations of files. But here's what I did:
Download the source code from codepoet cups-pdf-for-mac-os-x. (For non-macs, you can look at http://www.cups-pdf.de/) The readme is greatly detailed and if you read all of the instructions carefully, it will work, however I had a little trouble getting all the pieces, so I will outline exactly what I did in the hopes of saving someone else some trouble. For this, the directory with the source code is called "cups-pdfdownloaddir".
Compile cups-pdf.c contained in the src folder as the readme specifies:
gcc -09 -s -lcups -o cups-pdf cups-pdf.c
There may be a warning: ld: warning: option -s is obsolete and being ignored, but this posed no issue for me. Copy the binary into /usr/libexec/cups/backend. You will likely have to the sudo command, which will prompt you for your password. For example:
sudo cp /cups-pdfdownloaddir/src/cups-pdf /usr/libexec/cups/backend
Also, don't forget to change the permissions on this file--it needs root permissions (700) which can be changed with the following after moving cupd-pdf into the backend directory:
sudo chmod 700 /usr/libexec/cups/backend/cups-pdf
Edit the file contained in /cups-pdfdownloaddir/extra/cups-pdf.conf. Under the "PDF Conversion Settings" header, find a line under the GhostScript that reads #GhostScript /usr/bin/gs. I did not uncomment it in case I needed it, but simply added beneath it the line Ghostscript /usr/bin/pstopdf. (There should be no pre-cursor # for any of these modifications)
Find the line under GSCall that reads #GSCall %s -q -dCompatibilityLevel=%s -dNOPAUSE -dBATCH -dSAFER -sDEVICE=pdfwrite -sOutputFile="%s" -dAutoRotatePage\
s=/PageByPage -dAutoFilterColorImages=false -dColorImageFilter=/FlateEncode -dPDFSETTINGS=/prepress -c .setpdfwrite \
-f %s Again without uncommenting this, under this I added the line GSCall %s %s -o %s %s
Find the line under PDFVer that reads #PDFVer 1.4 and change it to PDFVer, no spaces or following characters.
Now save and exit editing before copying this file to /etc/cups with the following command
sudo cp cups-pdfdownloaddir/extra/cups-pdf.conf /etc/cups
Be careful of editing in a text editor because newlines in UNIX and Mac environments are different and can potentially ruin scripts. You can always use a perl command to remove them, but I'm paranoid and prefer not to deal with it in the first place.
You should now be able to open a program (e.g. Word, Excel, ...) and select File >> Print and find an available printer called CUPS-PDF. Print to this printer, and you should find your pdfs in /var/spool/cups-pdf/yourusername/ by default.
*Also, I figured this might be helpful because it helped me: if something gets screwed up in following these directions and you need to start over/get rid of it, in order to remove the driver you need to (1) remove the cups-pdf backend from /usr/libexec/cups/backend (2) remove the cups-pdf.conf from /etc/cups/ (3) Go into System Preferences >> Print & Fax and delete the CUPS-PDF printer.
This is how I successfully set up a pdf backend/filter for myself, however there are more details, and other information on customization contained in the readme file. Hope this helps someone else!

How do I get quicklisp to load rfc2388 in slime?

I'm trying to load hunchentoot via quicklisp in slime, and getting the following error:
READ error during COMPILE-FILE:
:ASCII stream decoding error on
#<SB-SYS:FD-STREAM
for "file [redacted]/dists/quicklisp/software/rfc2388-20120107-http/rfc2388.asd"
{100607B723}>:
the octet sequence #(196) cannot be decoded.
(in form starting at line: 29, column: 29,
file-position: 1615)
[Condition of type ASDF:LOAD-SYSTEM-DEFINITION-ERROR]
I get this when trying to run either:
(ql:quickload "hunchentoot")
Or simply:
(ql:quickload "rfc2388")
It seems that others are getting this too. I found one hint at a possible answer, saying:
The system file is encoded as UTF-8.
I'm not sure how to configure things so that SBCL on Windows starts with
UTF-8 as its default encoding for loading sources, but that's what you
need to do.
From there, I've tried (based on e.g. [this] adding the following to my emacs config:
(set-language-environment "UTF-8")
(setq slime-lisp-implementations
'((sbcl ("/opt/local/bin/sbcl") :coding-system utf-8-unix)))
(setq slime-net-coding-system 'utf-8-unix)
But... I still get the same error, even after completely re-starting emacs, to make sure I had a fresh Slime that was reading the above config.
So, what am I missing, and/or otherwise how can I get this to load?
Thanks in advance! (More thanks to come for a successful answer. ;)
Have you checked your locale settings? Emacs configuration only tells it what coding systems to set for communication between SLIME and SWANK.
You can check for locale settings with /usr/bin/locale, for example:
navi ~ » locale
LANG=pl_PL.UTF-8
LC_CTYPE=pl_PL.UTF-8
LC_NUMERIC=pl_PL.UTF-8
LC_TIME=pl_PL.UTF-8
LC_COLLATE="pl_PL.UTF-8"
LC_MONETARY=pl_PL.UTF-8
LC_MESSAGES=C
LC_PAPER=pl_PL.UTF-8
LC_NAME="pl_PL.UTF-8"
LC_ADDRESS="pl_PL.UTF-8"
LC_TELEPHONE="pl_PL.UTF-8"
LC_MEASUREMENT=pl_PL.UTF-8
LC_IDENTIFICATION=pl_PL.UTF-8
LC_ALL=
navi ~ »
Mine is setup for UTF-8 everywhere, as you can see, except for displaying 'C' messages.
Try this:
change into the .../quicklisp/dists/quicklisp/software/rfc2388* directory and load rfc2388.asd into a text editor.
Move down to the :author parameter of the defsystem form. Replace the author's name by the name given at the top of the file.
Store file using ASCII encoding.
Of course, when a new version of the library is published, the workaround gets lost. Or else store the modified project in local-projects.
With the original UTF-8 encoding still in effect, the DEBUGGER should present an INPUT-REPLACEMENT option to replace offending input characters by a replacement string. Choose that option, type "?" or "x" or any string you like at the prompt and then ENTER. The load then completes. Of course, that is not something you would like to do every time.
So the best idea is probably to send an email to the author and ask to provide an ascii version for quicklisp.
There should be a .cache directory in your HOME that contains all the fasl files. Sometimes removing those old fasl files seems to work for me when something goes wrong with compilation.
