Re: Leiningen in Python
Hi Rob,
Thanks for your helpful reply. I have finally had success.

Evidently not.
So I started from fresh again, just to be certain.

This wasn't necessary in the end, in my case.

My mistake, sorry.
(I should have remembered that new requires 2 args from before.)

I added your amended code to the python script to handle a second
argument.
Aside: if anyone cuts and pastes Rob's python code from a browser,
you may have to delete the whitespace after the 6 continuation
symbols (\) or else python (V2.6) complains.
So I have got past yesterday's issues and now have a standalone jar
file.
In case, it is helpful to others, the commands that I used
(virtually the same as in your last email) were:
E:\etc\clojure\Leiningen\lein.py clean
E:\etc\clojure\Leiningen\lein.py deps
E:\etc\clojure\Leiningen\lein.py compile
E:\etc\clojure\Leiningen\lein.py jar
E:\etc\clojure\Leiningen\lein.py uberjar
:: WARNING: Not 'java -jar helloworld.jar'. D'oh!
java -jar helloworld-standalone.jar
Thanks for your time with this.
Regards,
John.

Are you really sure that function `copy-to-jar` looks exactly like this:
(defmethod copy-to-jar :path [project jar-os spec]
(doseq [child (file-seq (file (:path spec)))]
(when-not (.isDirectory child)
(let [path (unix-path (str child))
path (re-sub (re-pattern (str "^" (unix-path (:root project
"" path)
path (re-sub #"^/resources" "" path)
path (re-sub #"^/classes" "" path)
path (re-sub #"^/src" "" path)
path (re-sub #"^/" "" path)]
(.putNextEntry jar-os (JarEntry. path))
(copy child jar-os)
I mean `unix-path` function is called twice not only once.
In order to see what is exactly the problem you need to comment out
`try-except` clause in core.clj in "-main" function.

And this message is totally OK. "new" command requires at least one
argument, e.g. project name:
lein.py new test_proj
But see below.

But there is still problem with passing arguments from windows
command line to leiningen. All arguments are considered as one
by Leiningen, so:
lein.py "new" "test_proj"
means for Leiningen:
lein.py "new test_proj"
I'm starting to think that it would be
nice to call leiningen as regular jar (I mean adding leiningen.clj
with "-main" function). Using "clojure.main" and "-e" is really
difficult on Windows.
@Phil what do you think about it?
Anyway I came up with this not very elegant soultion:
# part of lein.py
def run_leiningen(argv):
def escape_arg(s):
return s.replace("\\", "").replace("\"", "\\\"")
ARGS = ['"' + escape_arg(s) + '"' for s in argv]
CMD = ("java -Xbootclasspath/a:%s -client -cp %s clojure.main" \
+ " -e \"(use 'leiningen.core) (-main \\\"%s\\\")\"") \
% (quote_cp([CLOJURE_JAR]), quote_cp(CLASSPATH), ARGS[0])
if len(ARGS) == 2:
CMD = ("java -Xbootclasspath/a:%s -client -cp %s clojure.main" \
+ " -e \"(use 'leiningen.core) (-main \\\"%s\\\" \\\"%s\\\")\"")
\
% (quote_cp([CLOJURE_JAR]), quote_cp(CLASSPATH), ARGS[0],
ARGS[1])
elif len(ARGS) == 3:
CMD = ("java -Xbootclasspath/a:%s -client -cp %s clojure.main" \
+ " -e \"(use 'leiningen.core) (-main \\\"%s\\\" \\\"%s\\\"
\\\"%s\\\")\"") \
Re: Leiningen in Python
Hi Rob,
I made the changes src/leiningen/jar.clj that you suggested.
Then issued the commands:
E:\etc\clojure\Leiningen\lein.py clean
E:\etc\clojure\Leiningen\lein.py deps
E:\etc\clojure\Leiningen\lein.py compile
E:\etc\clojure\Leiningen\lein.py jar
E:\etc\clojure\Leiningen\lein.py uberjar
and they all work to compile the new Leiningen.
(Fyi, I originally didn’t have the 'lein.py deps' step
and this seems to be essential, in my case.)
Then in the python script (lein.py), I set
LEIN_JAR = expanduser("E:/keep/eclipse/3.5/git-leiningen/src/
leiningen-standalone.jar")
CLOJURE_JAR = expanduser("E:/keep/eclipse/3.5/git-leiningen/src/lib/
clojure-1.1.0-master-20091218.160125-7.jar")
i.e. to point at the newly compiled leiningen and the version of
clojure
that it downloaded into its 'lib' folder.
I then tried the simple example at
http://zef.me/2470/building-clojure-projects-with-leiningen
using this project.clj
(defproject helloworld "0.1"
:dependencies [[org.clojure/clojure "1.1.0-master-SNAPSHOT"]
[org.clojure/clojure-contrib "1.0-SNAPSHOT"]]
:main helloworld)
to correspond to the project.clj in E:/keep/eclipse/3.5/git-leiningen/
src
which contains
(defproject leiningen "1.1.0-SNAPSHOT"
:description "A build tool designed not to set your hair on fire."
:url "http://github.com/technomancy/leiningen";
:dependencies [[org.clojure/clojure "1.1.0-master-SNAPSHOT"]
[org.clojure/clojure-contrib "1.0-SNAPSHOT"]
[ant/ant-launcher "1.6.2"]
[jline "0.9.94"]
[org.apache.maven/maven-ant-tasks "2.0.10"]]
:dev-dependencies [[leiningen/lein-swank "1.0.0-SNAPSHOT"]]
:main leiningen.core)
I am able to compile the helloworld example:
E:\keep\clojure\helloworld>E:\etc\clojure\Leiningen\lein.py compile
[copy] Copying 2 files to E:\keep\clojure\helloworld\lib
Compiling helloworld
But 'lein.py uberjar' or 'lein.py jar' both produce stange errors:
E:\keep\clojure\helloworld>E:\etc\clojure\Leiningen\lein.py uberjar
Wrong number of arguments to task uberjar.
E:\keep\clojure\helloworld>E:\etc\clojure\Leiningen\lein.py jar
Wrong number of arguments to task jar.
and so does 'lein.py new'
E:\keep\clojure\helloworld>E:\etc\clojure\Leiningen\lein.py new
Wrong number of arguments to task new.
E:\keep\clojure\helloworld>E:\etc\clojure\Leiningen\lein.py version
Leiningen nil on Java 1.6.0_18-ea Java HotSpot(TM) Client VM
This seems to be a different issue (possibly with the lein.py
script?).
Any pointers would be very welcome.
Regards,
John.

Re: Leiningen in Python
Hi,
I am trying to use lein.py, from above, on Windows (Vista).
It works nicely for some commands (e.g. lein.py compile),
after removing the extra space in two places e.g.
'leiningen-%s-standalone .jar' ->
'leiningen-%s-standalone.jar'
and
'1.1.0-alpha-SNAPSHOT/cloju re-1.1.0-alpha-SNAPSHOT.jar' ->
'1.1.0-alpha-SNAPSHOT/clojure-1.1.0-alpha-SNAPSHOT.jar'
But I still have the following error with the 'lein.py install' and
'lein.py jar' commands:
E:\temp\leiningen\myproject> E:\etc\clojure\Leiningen\lein.py install
Exception in thread "main" java.util.regex.PatternSyntaxException:
Illegal/unsupported escape sequence near index 9
^E:\temp\leiningen\myproject
^ (NO_SOURCE_FILE:0)
at clojure.lang.Compiler.eval(Compiler.java:5274)
at clojure.lang.Compiler.eval(Compiler.java:5226)
...
E:\temp\leiningen\myproject> E:\etc\clojure\Leiningen\lein.py jar
Exception in thread "main" java.util.regex.PatternSyntaxException:
Illegal/unsupported escape sequence near index 9
^E:\temp\leiningen\myproject
^ (NO_SOURCE_FILE:0)
at clojure.lang.Compiler.eval(Compiler.java:5274)
at clojure.lang.Compiler.eval(Compiler.java:5226)
...
I am guessing that this means that the backslash in 'temp\leiningen'
needs to be escaped
somewhere in the python script (lein.py) above.
(I am not clear why the first backslash (in E:\temp) is not reported
as the error (index 4).)
I have tried many guesses (I am not familiar with python (V2.6)).
Can anyone make some suggestions?
Regards,
John.

As you have already found out you need only standalone leiningen jar,
which is downloaded by "lein.py".

Re: Leiningen in Python
I could not get the python script to work, so I switched to the
powershell version.
I now understand that the leiningen-1.0.0-SNAPSHOT.jar is a so-called
"uberjar" and contains all the dependencies for leiningen.
However, the python script assumes clojure is from a separate jar
which is not installed via lein self-install:
CLOJURE_JAR = expanduser("~/.m2/repository/org/clojure/clojure/1.1.0-
alpha-SNAPSHOT/clojure-1.1.0-alpha-SNAPSHOT.jar")
I don't know how to modify this to use the leiningen uberjar instead.

Re: Leiningen in Python
All,
I tried to use this script on Windows and it blew up real good! I'm a
Clojure, Java, and Leiningen newbie, so perhaps a kind soul can help
me out.
1. lein self-install "worked". It downloaded leiningen-1.0.0-
standalone.jar. However, that contradicts the description at
http://zef.me/2470/building-clojure-projects-with-leiningen which
indicates that self-install should download several jars, including
clojure itself. That didn't happen, and it looks like it would never
happen according to the python script. Also, I'd rather use one and
only one clojure, clojure-contrib, etc. for everything rather than
Leiningen using its own. Is this possible?
2. Any other lein command seems to require the clojure jar in the
repository ~/.m2/repository/org/clojure/clojure/1.1.0-alpha-SNAPSHOT/
clojure-1.1.0-alpha-SNAPSHOT.jar. Since I don't have one there, I
modified CLOJURE_JAR to point to my existing jar. Everything still
fails with this sort of error:
lein help
java.lang.NoClassDefFoundError: Files
Caused by: java.lang.ClassNotFoundException: Files
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:303)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:316)
Could not find the main class: Files. Program will exit.
Exception in thread "main"
I suspect the suspicious "Files" class name is coming from the fact
that I now have CLOJURE_JAR set as follows:
CLOJURE_JAR = expanduser("C:\\Program Files (x86)\\Clojure Box\\clojure
\\clojure-1.0.0.jar")
Looks like I'm getting bit by spaces in the path name. This would not
be an issue if lein had downloaded its own clojure jar during step 1
(no spaces in that path).
3. My clojure jar is clojure-1.0.0.jar from clojure org. The script
uses clojure-1.1.0-alpha-SNAPSHOT.jar, but a comment from the link
implies that this has been supplanted by 1.1.0-master.jar. In any
event, I don't know where either of these two things are. I tried
going to build.clojure.org, but all the build artifiacts there are
named clojure.jar.
4. BTW, what's the deal with this ".m2" directory (i.e., where does
the name come from)?
Thanks for any help you can provide!
Mike
