Please switch to a POSIX-compatible shell (e.g. BASH, KSH, ZSH). + +.. note:: + + STScI will not maintain a separate codebase of Anaconda's backend ``conda`` in order to implement CSH support. Feel free to + create an issue with the `developers <http://github.com/conda/conda/issues>`_. How does AstroConda differ from Ureka? ====================================== -TODO +Ureka and AstroConda both provide applications and libraries in binary form, however Ureka was a *one size fits all* distribution +which included every package in one giant tarball. If an end-user only really wanted a small set of packages they were forced +to install everything *and then some*. AstroConda is a *if the shoe fits wear it* distribution of packages. If an end-user +needs ``HSTCAL``, for example, they can install ``HSTCAL`` and omit much of the rest of HST's software suite. How often are updates released? =============================== -TODO +Updates to (STScI) software will be released as bugs are identified and squashed. The ``stsci-*`` metapackages, for example, provide +"releases" (i.e. a set of software used by our internal pipelines). After installing a release it is then possible to upgrade to the latest +out-of-band packages by simply running: + +```conda update -n astroconda --all``` + +Non-STScI software will be upgraded on an as-needed basis. See the `Contibuting Guide <contributing.html>`_ to learn more about asking +for updates to existing packages. + +What happened to SSBX? +====================== + +SSBX was a weekly release of STScI's software suite regardless of the stability of the codebase. This release was often times +broken and caused issues for external users. SSBX has been rolled into AstroConda as out-of-band package updates. This offers +a much better user experience, because as bugs are fixed, people will be able to upgrade without waiting until the following week. + +What happened to SSBDEV? +======================== + +SSBDEV was a nightly snapshot release of STScI's software suite. This release was often times broken and caused issues for +external users. Nightly snapshots are ***no longer available*** for use by the public. Updates to AstroConda will be made +directly as existing software is improved and/or new software is released. Why isn't IRAF installed by default? ==================================== -TODO +IRAF is an extremely large software package. Not every developer or scientist requires it. + +If you wish to use IRAF, simply install it: + +``conda install -n iraf27 python=2.7 iraf && source activate iraf27`` + +Why is IRAF/PyRAF less functional under Python 3? +================================================= + +The Python code in ``stsdas``, for example, is targeted specifically for Python 2.7 and earlier. If the demand for Python 3 +support under IRAF is great enough we may be able pull our resources to accommodate the community. It is recommended to install +IRAF into its own environment under Python 2.7: + +``conda create -n iraf27 python=2.7 iraf && source activate iraf27`` + -Why can't I install IRAF in a Python 3 environment? -=================================================== +Will AstroConda interfere with other scientific distributions (e.g. SciSoft)? +============================================================================= -TODO +**Probably**, however unlike Ureka we will not impose any restrictions on your environment or issue compatibility warnings at run-time. +It is your responsibility to maintain a functional shell environment so it does not conflict with your Anaconda installation. -Will AstroConda interfere with scientific software distributions (e.g. SciSoft)? -================================================================================ -TODO |
