Ticket #29022 – Description
v2 v28 1 This is a step toward #25486: "`$SAGE_LOCAL/bin/sage` should work in an environment without `SAGE_*` variables; and also useful for #29013.1 This ticket makes sagelib more independent from the environment variables set by `src/bin/sage-env` (`local/bin/sage-env`), and to remove assumptions regarding install locations of sagelib relative to `$SAGE_LOCAL`. 2 2 3 In a first step, we just set `SAGE_LOCAL`, but later packages' `spkg-configure` might be setting `MATHJAX_DIR` etc. 3 - To support users who want to install an experimental version of sagelib in other install locations, such as in a user site packages directory. 4 - For making sagelib available in a user's venv, as in the following example: 5 Without this ticket: 6 {{{ 7 $ sage -python -m venv --system-site-packages ~/personal-sage-venv/ 8 >>> import sage.env 9 >>> sage.env.SAGE_LOCAL 10 '/Users/mkoeppe/personal-sage-venv' # wrong 11 >>> import sage.all 12 RuntimeError: You must get the file local/bin/sage-maxima.lisp 13 }}} 14 With this ticket: 15 {{{ 16 >>> sage.env.SAGE_LOCAL 17 '/Users/mkoeppe/s/sage/sage-rebasing/worktree-algebraic-2018-spring/local' 18 >>> import sage.all 19 >>> 20 }}} 21 - To support #29013/#27824: spkg-configure.m4 for python3 22 - To make it possible for distributions to use a stock `src/sage/env.py` (providing a custom `src/sage/env_conf.py`). 4 23 5 The hope is that distributions would be able to use a stock `src/sage/env.py` and a custom `src/sage/env_conf.py`. 24 In a first step, we just set `SAGE_LOCAL`, but also `SAGE_ROOT` could be added (for developer conveniences such as sage.misc.edit_module); and later packages' `spkg-configure` might be setting `MATHJAX_DIR` etc. 6 25 7 26 In a follow-up ticket, `src/sage/env_config.py` would actually be generated by `src/setup.py`, not `configure`.
