System information

64-bit Linux OS
GNU Emacs 24.1.1 (x86_64-unknown-linux-gnu, X toolkit, Xaw scroll bars) of 2012-06-25


On sage-mode project page it is said that sage-mode should be installed with the following command:

sage -f sage-mode-0.7.spkg

This does not work though sage-mode-0.6.spkg can be installed this way without any problems.

In order to install this package I had to download it manually. Here is the correct installation command:

sage -f ~/Downloads/sage-mode-0.7.spkg

I have put the following code into my emacs.el:

(add-to-list 'load-path (expand-file-name
(require 'sage "sage")
(setq sage-command "/home/maksim/Applications/sage/sage")

Syntax highlighting

Running M-x sage-mode in Emacs leads to the following error message:

Symbol's value as variable is void: python-source-modes

though package python is a built-in one and works well.

In order to avoid this problem I have added the following code:

(setq python-source-modes 'python-mode)

This made sage-mode work properly (at least syntax highlighting).


run-sage command does not work. It reports

Symbol's value as variable is void: sage-buffer

Setting this variable to nil does not help:

Symbol's function definition is void: python-args-to-list

The file .../lisp/progmodes/python.el in the Emacs distribution does contain this function.

It sounds like (based on the python-source-modes error) you are using fgallina's new python.el. Sadly, sage-mode doesn't support that yet. I have an experimental spkg with some support. If you want to try and report any problems to bitbucket (or even better submit patches/pull requests), that would be great. You can comment on the fgallina ticket, or create new ones.

Ok, I *thought* you were the maintainer. Can you update accordingly? I guess just updating the contact, bitbucket link (in the sense that yours is now the "official" repository) and maybe making sure to continue to attach old versions there, if we deem that useful. Otherwise people will keep contacting Nick.

New version is hard to install if Sage was installed as normal user. SAGE_ROOT and SAGE_DATA are not defined (incorrect Sage installation?) and one have to set them for the user and also for root (the installation script requires root privileges to do something with Python).

New version does not have `python-source-modes` problem but still reports about undefined `sage-buffer` variable after `M-x run-sage`. Setting `sage-buffer` to nil lets me run Sage but it reports "`Symbol's function definition is void: python-send-string`". The buffer with Sage appears but I can not type anything there.

I can move cursor in that buffer. When I try to type numbers there is no response. Attempt to type letters make Emacs behave like I do something wrong (e.g. move up when at the top of buffer).

I've updated the wiki, and SPKG.txt.

I can't help with the rest, but the "current" Sage-mode is still 0.6, as listed at the list of optional spkgs. That is what this will do without a URL.

But if you specify a URL for sage -f http://url/for/sage-mode-0.7.spkg, that should work fine. I've opened Trac 13176 for upgrading the optional spkg to this.

I have also tried 0.6 and saw no difference

You mean no difference in the other problems? Unfortunately, I can't help with those :( but I'll note them at the relevant ticket.

Ergoemacs changes load-path variable and makes Emacs load some packages from wrong place, i.e. ergoemacs_1.9.3.1/packages.

Ergoemacs contains old version of python-related modules. The problem can be solved by [re]moving some files from ergoemacs_1.9.3.1/packages directory. For this particular issue they are python.el, python.elc, python-mode.el and python-mode.elc.
