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.
