In exceptional cases (custom installation, malfunctions elsewhere), `pyenv-commands --sh` may return nothing.
In non-Fish, this would cause "syntax error near unexpected token `)'" in `pyenv()`.
Bash does not allow to specify a `case` option that would never match.
This works around it by defaulting to `/`. Commands, being filenames, can never match it.
In Fish, nothing needs to be done: it apparently does interpret a `case` without argument as one that never matches.
In some advanced shell setups, the order of custom-added PATH entries is important.
We disregard it by default, always pushing shims to the front of PATH,
to ensure that Pyenv works even in poorly maintained shell environments
and with minimal hassle for non-export users
(an attempt to do the opposite (#1898) has ended in a disaster).
Some advanced users are however ready and able to carefully maintain their environment
and deal with breakages and inconvenience. This option is for them.
We're going to eliminate the need to mandatorily use `pyenv init --path`.
We can't delete it yet for backward compatibility.
Besides, there's one other use case for it: to enable shims but without
shell integration, e.g. for noninteractive shells.
To be a full-fledged replacement for `pyenv init -` however,
it needs to do rehashing.
Now the setup is to add to both rc and profile:
1) set PYENV_ROOT
(can do it unconditionally -- since if you change it,
you need to update all places anyway since any of them can be run first)
2) Add `pyenv` to PATH if not already there
3) eval "$(pyenv init -)"
Not a breaking change, old setup will continue to work.
Sometimes it is convenient to be able to temporarily disable something
in a version-file. Because these files often aren't necessarily tracked
in a SCM, especially when working with virtualenvs, the SCM diffs won't
help with showing removed lines which are currently the only way to
disable something.
The test "prefix for system in /" is duplicated in test/prefix.bats.
Both tests are completely identical. This commit removes the
duplication.
It appears that the culprit is this merge from rbenv/master, from 2016:
cf1beda362
With the current development version of bats, this leads to the
following error when running `make test`:
Error:
Duplicate test name(s) in file
"/home/travis/build/pyenv/pyenv/test/prefix.bats":
test_prefix_for_system_in_-2f
Note that the development version is what pyenv's Makefile uses. With
the latest release of bats, the duplication only leads to a warning:
bats warning:
duplicate test name(s) in /src/test/prefix.bats:
test_prefix_for_system_in_-2f
This was imported semi-automatically in 0965577, but `ruby -S` is
different from `python -S`.
`ruby -S`: look for the script using PATH environment variable
`python -S`: don't imply 'import site' on initialization
All scripts in libexec/ (excluding pyenv) are called through pyenv,
therefore the shebang lines are not necessary. On some systems this
provides a measurable increase in performance of the shell prompt.
