"""Main entry point for Pype command.
|
|
|
|
Bootstrapping process of Pype is as follows:
|
|
|
|
`PYPE_PATH` is checked for existence - either one from environment or
|
|
from user settings. Precedence takes the one set by environment.
|
|
|
|
On this path we try to find zip files with `pype-repositories-v3.x.x.zip`
|
|
format.
|
|
|
|
If no Pype repositories are found in `PYPE_PATH (user data dir)
|
|
then **Igniter** (Pype setup tool) will launch its GUI.
|
|
|
|
It can be used to specify `PYPE_PATH` or if it is _not_ specified, current
|
|
*"live"* repositories will be used to create such zip file and copy it to
|
|
appdata dir in user home. Version will be determined by version specified
|
|
in Pype module.
|
|
|
|
If Pype repositories zip file is found in default install location
|
|
(user data dir) or in `PYPE_PATH`, it will get list of those zips there and
|
|
use latest one or the one specified with optional `--use-version` command
|
|
line argument. If the one specified doesn't exist then latest available
|
|
version will be used. All repositories in that zip will be added
|
|
to `sys.path` and `PYTHONPATH`.
|
|
|
|
If Pype is live (not frozen) then current version of Pype module will be
|
|
used. All directories under `repos` will be added to `sys.path` and
|
|
`PYTHONPATH`.
|
|
|
|
Pype depends on connection to `MongoDB`_. You can specify MongoDB connection
|
|
string via `AVALON_MONGO` set in environment or it can be set in user
|
|
settings or via **Igniter** GUI.
|
|
|
|
Todo:
|
|
Move or remove bootstrapping environments out of the code.
