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.

I have a few lines of configurations that I need in my rsyslgog.
if $programname == 'project' then /var/log/file.log
When added to the end of the main rsyslog configuration file, /etc/rsyslog.conf, this configuration appears to be valid and functional.
However, when using the rsyslog.d directory I get a syntax error.
error during parsing file /etc/rsyslog.d/project.conf, on or before line 2: syntax error on token '==' [v8.32.0 try http://www.rsyslog.com/e/2207 ]
Is there anything in the main config that has to be parsed in advance, or is this a bug that should be reported to Fedora 27 developers?
As rsyslog author, I would assume that there is some include right in front of it that somehow renders your (valid) construct invalid. Red Hat unfortunately tends to stick to obsolete legacy format, and things like these can easily happen when this is used (after all, this was why we obsoleted it).
To hunt this down, I would check the config include that is included immediately in front of your own. If included via wildcards, the include order is sorted by filename.
Sorry, it was my bad. The configuration for my rsyslog config file was rewritten by my installer bash script, and that interpreted the $ sign as variable within the string. I should have double-checked the correctness of my config file.
I'm having trouble installing Homebrew, and it looks like the problem (invalid byte sequence in UTF-8 (ArgumentError) error message) is due to a fault in my PATH. when I run echo $PATH, I get the following (be sure to scroll to the far right in the code block below to see the fault):
/usr/local/mysql/bin:/opt/subversion/bin/:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:PATH=/usr/local/share/python:$PATH:PATH=/usr/local/share/npm/bin:$PATH:export PATH��:/usr/local/git/bin
I have no idea where those strange characters just before the /usr/local/git/bin path are coming from. I'm using bash (tried zshell, same problem). I can't find where this coming from. my .bash_profile file looks clean, too.
Examine your ~/.profile, ~/.bash_profile, and ~/.bashrc files. It is also possible that these values are being set in /etc/profile or other system-wide files, but the nature of the errors is such that I would assume they are the result of your own manual edits of your personal files. You're the best judge to decide what you may have changed and when.
Look for entries such as the following:
PATH='/usr/local/share/python:$PATH'
PATH='PATH=/usr/local/share/npm/bin:$PATH'
PATH='export PATH��:/usr/local/git/bin'
They should instead look like
PATH=/usr/local/share/python:$PATH
PATH=/usr/local/share/npm/bin:$PATH
PATH=$PATH:/usr/local/git/bin
# Not strictly necessary -- PATH is already exported
export PATH
See a pattern? These all add a value to PATH by setting it to prefix:$PATH or $PATH:suffix where the new prefix or suffix is the directory where you have installed a local package. Whether the new value should be a prefix or a suffix is probably of little consequence -- except if you are trying to override a system version (say, your /usr/local/git is installed because /usr/bin/git is too old -- then, it's important that your local version comes first in the PATH). There is also a minuscule speed difference the first time you run a command; the shell has to look in more places before finding it if it's at the end of the PATH.
The difference in quoting is significant -- PATH=$PATH:suffix expands to the old value of PATH with :suffix added on, whereas PATH='$PATH:suffix' replaces the old value of PATH with the literal string $PATH with :suffix added on. You're lucky none of this has ended up replacing your original PATH completely, which would render your shell by and large inoperable (at least until you discover that you have to use /bin/ls instead of just ls).
I'm trying to add a Chinese localisation to a scaffolded Yesod site. I have a zh.msg message file saved as UTF-8 format using Notepad in Windows, but when I run cabal install in the project directory, I get this:
Handler\Home.hs:15:11:
Not in scope: data constructor `MsgHello'
Perhaps you meant `Msg<stderr>: hPutChar: invalid argument (invalid character)
The line in question is where I render my homepage:
$(widgetFile "homepage")
I changed both message files to be Unicode formatted instead of UTF-8, and get this message instead:
Foundation.hs:1:1:
Exception when trying to run compile-time code:
Cannot decode byte '\xff': Data.Text.Encoding.Fusion.streamUtf8: invalid UTF-8 stream
So I guess UTF-8 is the way to go... somehow.
(I'm using Notepad because I haven't set up gVim to render Unicode characters. It's apparently a bit of a feat.)
When I went to commit my changes I discovered the issue. The diff for my English file looked like this:
-Hello: Hello
+<U+FEFF>Hello: Hello
I guess notepad added the character in, and it was working its way into the Haskell code. I solved it using vim according to this answer.
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!
The .XFDL file extension identifies XFDL Formatted Document files. These belong to the XML-based document and template formatting standard. This format is exactly like the XML file format however, contains a level of encryption for use in secure communications.
I know how to view XFDL files using a file viewer I found here. I can also modify and save these files by doing File:Save/Save As. I'd like, however, to modify these files on the fly. Any suggestions? Is this even possible?
Update #1: I have now successfully decoded and unziped a .xfdl into an XML file which I can then edit. Now, I am looking for a way to re-encode the modified XML file back into base64-gzip (using Ruby or the command line)
If the encoding is base64 then this is the solution I've stumbled upon on the web:
"Decoding XDFL files saved with 'encoding=base64'.
Files saved with:
application/vnd.xfdl;content-encoding="base64-gzip"
are simple base64-encoded gzip files. They can be easily restored to XML by first decoding and then unzipping them. This can be done as follows on Ubuntu:
sudo apt-get install uudeview
uudeview -i yourform.xfdl
gunzip -S "" < UNKNOWN.001 > yourform-unpacked.xfdl
The first command will install uudeview, a package that can decode base64, among others. You can skip this step once it is installed.
Assuming your form is saved as 'yourform.xfdl', the uudeview command will decode the contents as 'UNKNOWN.001', since the xfdl file doesn't contain a file name. The '-i' option makes uudeview uninteractive, remove that option for more control.
The last command gunzips the decoded file into a file named 'yourform-unpacked.xfdl'.
Another possible solution - here
Side Note: Block quoted < code > doesn't work for long strings of code
The only answer I can think of right now is - read the manual for uudeview.
As much as I would like to help you, I am not an expert in this area, so you'll have to wait for someone more knowledgable to come down here and help you.
Meanwhile I can give you links to some documents that might help you:
UUDeview Home Page
Using XDFLengine
Gettting started with the XDFL Engine
Sorry if this doesn't help you.
You don't have to get out of Ruby to do this, can use the Base64 module in Ruby to encode the document like this:
irb(main):005:0> require 'base64'
=> true
irb(main):007:0> Base64.encode64("Hello World")
=> "SGVsbG8gV29ybGQ=\n"
irb(main):008:0> Base64.decode64("SGVsbG8gV29ybGQ=\n")
=> "Hello World"
And you can call gzip/gunzip using Kernel#system:
system("gzip foo.something")
system("gunzip foo.something.gz")
