We may want to work on top of an existing patch and this where `rad
|
|
patch checkout` comes into play. So, first we will create a patch to
|
|
set up the workflow.
|
|
|
|
```
|
|
$ git checkout -b flux-capacitor-power
|
|
$ touch REQUIREMENTS
|
|
```
|
|
|
|
Here the instructions are added to the project's README for 1.21 gigawatts and
|
|
commit the changes to git.
|
|
|
|
```
|
|
$ git add REQUIREMENTS
|
|
$ git commit -v -m "Define power requirements"
|
|
[flux-capacitor-power 3e674d1] Define power requirements
|
|
1 file changed, 0 insertions(+), 0 deletions(-)
|
|
create mode 100644 REQUIREMENTS
|
|
```
|
|
|
|
Once the code is ready, we open (or create) a patch with our changes for the project.
|
|
|
|
``` (stderr)
|
|
$ git push rad -o patch.message="Define power requirements" -o patch.message="See details." HEAD:refs/patches
|
|
✓ Patch 6ff4f09c1b5a81347981f59b02ef43a31a07cdae opened
|
|
To rad://z42hL2jL4XNk6K8oHQaSWfMgCL7ji/z6MknSLrJoTcukLrE435hVNQT4JUhbvWLX4kUzqkEStBU8Vi
|
|
* [new reference] HEAD -> refs/patches
|
|
```
|
|
|
|
Now, let's checkout the patch that we just created:
|
|
|
|
```
|
|
$ rad patch checkout 6ff4f09
|
|
✓ Switched to branch patch/6ff4f09
|
|
✓ Branch patch/6ff4f09 setup to track rad/patches/6ff4f09c1b5a81347981f59b02ef43a31a07cdae
|
|
```
|
|
|
|
Note that `rad patch checkout` can be used to switch to the patch branch
|
|
as long as we haven't made changes to it.
|
|
|
|
```
|
|
$ git checkout master -q
|
|
$ rad patch checkout 6ff4f09
|
|
✓ Switched to branch patch/6ff4f09
|
|
```
|
|
|
|
Now, let's add a README too!
|
|
|
|
```
|
|
$ touch README.md
|
|
$ git add README.md
|
|
$ git commit --message "Add README, just for the fun"
|
|
[patch/6ff4f09 27857ec] Add README, just for the fun
|
|
1 file changed, 0 insertions(+), 0 deletions(-)
|
|
create mode 100644 README.md
|
|
```
|
|
|
|
We can now finish off the update:
|
|
|
|
``` (stderr)
|
|
$ git push rad -o patch.message="Add README, just for the fun"
|
|
✓ Patch 6ff4f09 updated to revision 0c0942e2ff2488617d950ede15567ca39a29972e
