OK

Here is a detailed action:

Replace:

(define (python-launcher)

  (if (url-exists? "$TEXMACS_HOME_PATH/plugins/tmpy")

      (string-append "python \""

                     (getenv "TEXMACS_HOME_PATH")

                     "/plugins/tmpy/session/tm_python.py\"")

      (string-append "python \""

                     (getenv "TEXMACS_PATH")

                     "/plugins/tmpy/session/tm_python.py\"")))

With:

(define (python-launcher)

  (if (url-exists? "$TEXMACS_HOME_PATH/plugins/tmpy")

      (string-append "/path/to/your/python \""

                     (getenv "TEXMACS_HOME_PATH")

                     "/plugins/tmpy/session/tm_python.py\"")

      (string-append "/path/to/your/python \""

                     (getenv "TEXMACS_PATH")

                     "/plugins/tmpy/session/tm_python.py\"")))

I will document the detailed steps for the upcoming TeXmacs 2.1 .

Under progs, there is init-python.scm. Just change the python-launcher.

 

I  have seen it but do not understand what I have to change.

Have you read the README.md?

Ditto.  I guess I need more detailed instructions like before. 

The python-launcher is the function that constructs a command to launcher the underlying python process. We may provide menu entries to choose the available python version later.

Dear Max, 

On a Mac OS X I am trying to change python environments in TeXmacs-1.99.11.app. 

As you had advised in the past, in previous versions of TeXmacs, like 1.99.8, I was changing the first line of the file

/Applications/TeXmacs-1.99.8.app/Contents/Resources/share/TeXmacs/plugins/python/bin/tm_python

However, in  /Applications/TeXmacs-1.99.8.app/Contents/Resources/share/TeXmacs/plugins/python/ 

there is no bin; its contents are README.md, doc and progs.  What should I do?

Thank you, Alkis
