What I'm looking for is this kind of command line interaction at the Windows command line:
C:\temp1>clj some_script.clj
C:\temp2>
Where some_script.clj contains something like:
(cd "c:\\temp2")
So the question is - how do I implement the function cd? Have experimented with clojure.java.shell, but it does not look like the lib I need. This might be a simple question, the problem might be that I'm not fluent in Java?!
You can't do this in Java, so you can't do it in Clojure. See Changing the current working directory in Java?
clojure can do this.
You only need to change a dynamic global variable called *sh-dir*. run the following code in your repl:
(use '[clojure.java.sh])
(sh "ls")
=> {:exit 0, :out "LICENSE\nREADME.md\nauto_deploy.iml\ndoc\nproject.clj\nresources\nsrc\ntarget\ntest\n", :err ""}
(binding [*sh-dir* "c:/"] (sh "ls"))
{:exit 0,
:out "$360Section

$Recycle.Bin

",
:err ""}
see the doc for more info. you can use (alter-var-root #'clojure.java.shell/*sh-dir* (constantly "the-cd-path")) to change it constantly. Thanks for isaac telling me about this.
Hope this helps.

So every example I've looked up indicates this is how one is supposed to do it but I think I may have found a bug unless there's another way to do this.
I'm using upload! to upload assets to a remote list of servers. The task looks like this:
desc "Upload grunt compiled css/js."
task :upload_assets do
on roles(:all) do
%w{/htdocs/css /htdocs/js}.each do |asset|
upload! "#{fetch(:local_path) + asset}", "#{release_path.to_s + '/' + asset}", recursive: true
end
end
end
If local_path is defined as an absolute path such as:
set :local_path:, '/home/dcmbrown/projects/ABC'
This works fine. However if I do the following:
set :local_path:, '~/projects/ABC'
I end up getting the error:
The deploy has failed with an error: Exception while executing on ec2-54-23-88-125.us-west-2.compute.amazon.com: No such file or directory - ~/projects/ABC/htdocs/css
It's not a ' vs " issue as I've tried both (and I didn't think capistrano paid attention to that anyway).
Is this a bug? Is there a work around? Am I just doing it wrong?
I ended up discovering the best way to do this is to actually use path expansion! (headsmack)
irb> File.expand_path('~dcmbrown/projects/ABC')
=> "/home/dcmbrown/projects/ABC"
Of course what I'd like is to do automatic path expansion but you can't have everything. I think I was mostly dumbstruck that it didn't automatically; so much so I spent a couple of hours trying to figure out why it didn't work and ended up wasting time asking here. :(
I don't think the error is coming from the remote server, it just looks like it since it's running that upload command in the context of a deploy.
I just created a single cap task to just do an upload using the "~" character and it also fails with
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy#XXX: No such file or directory # rb_file_s_stat - ~/Projects/testapp/public/404.html
It appears to be a Ruby issue not Capistrano as this also fails in a Ruby console
~/Projects/testapp $ irb
2.2.2 :003 > File.stat('~/Projects/testapp/public/404.html')

I would suggest the following
1.Close Emacs,then open it
2.Create new file by C-x C-f
3.enter valid sml code in the file wc you created and named test.sml say
4.C-x C-s to save it
5.M-x run-sml and press return twice
6.In the sml REPL enter use "test.sml";press return
7.This is it!!!
Make sure that the directory before you run sml is the same one as the one where the file exists. Otherwise, you must use the file's absolute path. Take a look at this question which deals with the same problem (and suggests it might be an issue with file not being specified correctly).
This is very simple to recreate.
If my script foo.py is:
import scipy
Then run:
python pyinstaller.py --onefile foo.py
When I launch foo.exe I get:
WARNING: file already exists but should not: C:\Users\username\AppData\Local\Temp\_MEI86402\Include\pyconfig.h
I've tested a few versions but the latest I've confirmed is 2.1dev-e958e02 running on Win7, Python 2.7.5 (32 bit), Scipy version 0.12.0
I've submitted a ticket with the Pyinstaller folks but haven't heard anything yet. Any clues how to debug this further?
You can hack the spec file to remove the second instance by adding these lines after a=Analysis:
for d in a.datas:
if 'pyconfig' in d[0]:
a.datas.remove(d)
break
The answer by wtobia# worked for me. See https://github.com/pyinstaller/pyinstaller/issues/783
Go to C:\Python27\Lib\site-packages\PyInstaller\build.py
Find the def append(self, tpl): function.
Change if tpl[2] == "BINARY": to if tpl[2] in ["BINARY", "DATA"]:
Expanding upon Ilya's solution, I think this is a little bit more robust solution to modifying the spec file (again place after the a=Analysis... statement).
a.datas = list({tuple(map(str.upper, t)) for t in a.datas})
I only tested this on a small test program (one with a single import and print statement), but it seems to work. a.datas is a list of tuples of strings which contain the pyconfig.h paths. I convert them all to lowercase and then dedup. I actually found that converting all of them all to lowercase was sufficient to get it to work, which suggests to me that pyinstaller does case-sensitive deduping when it should be case-insensitive on Windows. However, I did the deduping myself for good measure.
I realized that the problem is that Windows is case-insensitive and these 2 statements are source directories are "duplicates:
include\pyconfig.h
Include\pyconfig.h
My solution is to manually tweak the .spec file with after the a=Analysis() call:
import platform
if platform.system().find("Windows")>= 0:
a.datas = [i for i in a.datas if i[0].find('Include') < 0]
This worked in my 2 tests.
A more flexible solution would be to check ALL items for case-insensitive collisions.
I ran the archive_viewer.py utility (from PyInstaller) on one of my own --onefile executables that has the same error and found that pyconfig.h is included twice:
(31374007, 6521, 21529, 1, 'x', 'include\\pyconfig.h'),
(31380528, 6521, 21529, 1, 'x', 'Include\\pyconfig.h'),
(31387049, 984, 2102, 1, 'x', 'pytz\\zoneinfo\\CET'),
Sadly though, I don't know how to fix it.
PyInstaller Manual link:
http://www.pyinstaller.org/export/d3398dd79b68901ae1edd761f3fe0f4ff19cfb1a/project/doc/Manual.html#archiveviewer
Consider the following:
(directory (make-pathname :directory '(:absolute "Users" "gazonk" "foo" "*")
:name :wild))
This breaks because one of the directories contains the character ";".
If the "*" above is removed, the code returns a directory listing where ";" is escaped.
It seems I cannot make it go further down because some directories contain a ";"
Is there a fix for this?
Any and all commends appreciated. Thank you.
Confirmed. I see the same behavior with ccl 1.9 (64-bit or 32-bit) on Mac OS X 10.8.
I created an empty subdirectory using mkdir 'a;b' and I see:
(make-pathname :directory '(:absolute "Users" "gazonk" "foo" "*") :name :wild))
> Error: Illegal directory string "/Users/gazonk/foo/a;b/"
> While executing: CCL::%DIRECTORY-STRING-LIST, in process listener(1).
Update:
Based on Rainer's comment, it sounds like this is likely a ccl bug.
Recommend asking on the #ccl irc channel or submitting a bug report here (requires registration).
I installed moodle 1.9.12 and now I want to use Algebra notation in content. I enable "TeX Notation" and "Algebra Notation" in administrator panel and also install mimetext and dvips and Imagemagic on the server. fortunately Tex Notation works fine but I got the following error for Algebra:
sh: /var/www/html/moodle/filter/tex/mimetex.linux: not found
The shell command
"/var/www/html/moodle/filter/tex/mimetex.linux" -e "/var/www/moodledata/filter/algebra/de06d6c44d98ba4e42dffca988bf530b.gif" -- '\Large \frac{\sin\left(z\right)}{x^{2}+y^{2}}'
returned status = 127
File size of mimetex executable /var/www/html/moodle/filter/tex/mimetex.linux is 830675
The file permissions are: 100775
The md5 checksum of the file is 56bcc40de905ce92ebd7b083c76e019e
Image not found!
Note: /var/www/html/moodle/filter/tex/mimetex.linux exists on the server and is executable!!!
What is the problem?? Any idea?????
From what you have described, calling the general tex filter debug page works and does not show up the same error.
/filter/tex/texdebug.php works, but /filter/algebra/algebradebug.php does not.
If this is the case, perhaps you could check for an open_basedir, or safe_mode_exec_dir being set to include the current working directory, or otherwise restricting the execution of /var/www/html/moodle/filter/tex/mimetex.linux, while the current working directory is /var/www/html/moodle/filter/algebra.
You could look at this by visiting /admin/phpinfo.php at your site, and look carefully at the effective values of open_basedir, safe_mode and safe_mode_exec_dir.
You could also check the apache error log or add the following lines to the top of the algebra debug php file, and you might see some extra error messages:
$CFG->debug = 6143 ;
$CFG->debugdisplay= 1 ;
Hope that helps
