# In case of emergency
|
|
|
|
|
|
|
|
In case wraptool is down we have created a backup script that you can
|
|
|
|
use to download wraps directly from the GitHub repos. It is not as
|
|
|
|
slick and may have bugs but at least it will allow you to use wraps.
|
|
|
|
|
|
|
|
## Using it
|
|
|
|
|
|
|
|
To list all available wraps:
|
|
|
|
|
|
|
|
ghwt.py list
|
|
|
|
|
|
|
|
To install a wrap, go to your source root, make sure that the
|
|
|
|
`subprojects` directory exists and run this command:
|
|
|
|
|
|
|
|
ghwt.py install <projectname> [<branchname>]
|
|
|
|
|
|
|
|
This will stage the subproject ready to use. If you have multiple
|
|
|
|
subprojects you need to download them all manually.
|
|
|
|
|
|
|
|
Specifying branch name is optional. If not specified, the list
|
|
|
|
of potential branches is sorted alphabetically and the last branch is
|
|
|
|
used.
|
|
|
|
|
|
|
|
*Note* The tool was added in 0.32.0, for versions older than that you
|
|
|
|
need to delete the `foo.wrap` file to work around this issue.
|
|
|
|
|
|
|
|
## How to upgrade an existing dir/fix broken state/any other problem
|
|
|
|
|
|
|
|
Nuke the contents of `subprojects` and start again.

|

|
## Known issues
|
|
|
|
|
|
|
|
Some repositories show up in the list but are not installable. They
|
|
|
|
would not show up in the real WrapDB because they are works in
|
|
|
|
progress.
|
|
|
|
|
|
|
|
GitHub web API limits the amount of queries you can do to 60/hour. If
|
|
|
|
you exceed that you need to wait for the timer to reset.
