repo命令帮助信息汇总(附生成脚本)
有时想查看repo命令的帮助信息，但是每次都需要去某个repo仓库下运行"repo help cmd"命令很不方便，所以这里将其统一汇总到一起。repo命令比较多，以前每个命令都单独运行然后抓取输出，这次写了个脚本，自动运行并保存输出。
本文主要分文两个部分，第1部分汇总repo命令的帮助信息；第2部分附上批量运行repo命令并抓取输出的脚本，输出格式有两种，包括纯文本方式和markdown方式，稍微修改就可以用于其他命令的批量运行，如git命令或bash命令什么的。
本文的repo命令帮助汇总信息就是通过markdown方式生成的。

deleting it (and all its history) from your local repository.
It is equivalent to "git branch -D ".
Options:
-h, --help show this help message and exit
2. repo branch
$ repo help branch
Summary
-------

--------------
The branch display output by this command is organized into four
columns of information; for example:
*P nocolor | in repo
repo2 |
The first column contains a * if the branch is the currently
checked out branch in any of the specified projects, or a blank
if no project has the branch checked out.
The second column contains either blank, p or P, depending upon
the upload status of the branch.
(blank): branch not yet published by repo upload
P: all commits were published by repo upload
p: only some commits were published by repo upload
The third column contains the branch name.
The fourth column (after the | separator) lists the projects that
the branch appears in, or does not appear in. If no project list
is shown, then the branch appears in all projects.

4. repo checkout
$ repo help checkout
Summary
-------
Checkout a branch for development
Usage: repo checkout [...]
Options:
-h, --help show this help message and exit
Description
-----------
The 'repo checkout' command checks out an existing branch that was
previously created by 'repo start'.
The command is equivalent to:
repo forall [...] -c git checkout
5. repo cherry-pick
$ repo help cherry-pick
Summary
-------
Cherry-pick a change.
Usage: repo cherry-pick
Options:
-h, --help show this help message and exit
Description
-----------
'repo cherry-pick' cherry-picks a change from one branch to another. The
change id will be updated, and a reference to the old change id will be
added.
6. repo diff
$ repo help diff
Summary
-------
Show changes between commit and working tree
Usage: repo diff [...]
The -u option causes 'repo diff' to generate diff output with file paths
relative to the repository root, so the output can be applied
to the Unix 'patch' command.
Options:
-h, --help show this help message and exit
-u, --absolute Paths are relative to the repository root
7. repo diffmanifests
$ repo help diffmanifests
Summary
-------
Manifest diff utility
Usage: repo diffmanifests manifest1.xml [manifest2.xml] [options]
Options:
-h, --help show this help message and exit
--raw Display raw diff.
--no-color does not display the diff in color.
--pretty-format=
print the log using a custom git pretty format string
Description
-----------
The repo diffmanifests command shows differences between project
revisions of manifest1 and manifest2. if manifest2 is not specified,
current manifest.xml will be used instead. Both absolute and relative
paths may be used for manifests. Relative paths start from project's
".repo/manifests" folder.
The --raw option Displays the diff in a way that facilitates parsing,
the project pattern will be [] and the commit pattern will be with status
values respectively :
A = Added project
R = Removed project
C = Changed project
U = Project with unreachable revision(s) (revision(s) not found)
for project, and
A = Added commit
R = Removed commit
for a commit.
Only changed projects may contain commits, and commit status always
starts with a space, and are part of last printed project. Unreachable
revisions may occur if project is not up to date or if repo has not been
initialized with all the groups, in which case some projects won't be
synced and their revisions won't be found.
8. repo download
$ repo help download
Summary
-------
Download and checkout a change
Usage: repo download {project change[/patchset]}...
Options:
-h, --help show this help message and exit
-c, --cherry-pick cherry-pick instead of checkout
-r, --revert revert instead of checkout
-f, --ff-only force fast-forward merge
Description
-----------
The 'repo download' command downloads a change from the review system
and makes it available in your project's local working directory.
9. repo forall
$ repo help forall
Summary
-------
Run a shell command in each project
Usage: repo forall [...] -c [...]
repo forall -r str1 [str2] ... -c [...]"
Options:
-h, --help show this help message and exit
-r, --regex Execute the command only on projects matching regex or
wildcard expression
-i, --inverse-regex Execute the command only on projects not matching
regex or wildcard expression
-g GROUPS, --groups=GROUPS
Execute the command only on projects matching the
specified groups
-c, --command Command (and arguments) to execute
-e, --abort-on-errors
Abort if a command exits unsuccessfully
Output:
-p Show project headers before output
-v, --verbose Show command error messages
-j JOBS, --jobs=JOBS
number of commands to execute simultaneously
Description
-----------
Executes the same shell command in each project.
The -r option allows running the command only on projects matching regex
or wildcard expression.
Output Formatting
-----------------
The -p option causes 'repo forall' to bind pipes to the command's stdin,
stdout and stderr streams, and pipe all output into a continuous stream
that is displayed in a single pager session. Project headings are
inserted before the output of each command is displayed. If the command
produces no output in a project, no heading is displayed.
The formatting convention used by -p is very suitable for some types of
searching, e.g. `repo forall -p -c git log -SFoo` will print all commits
that add or remove references to Foo.
The -v option causes 'repo forall' to display stderr messages if a
command produces output only on stderr. Normally the -p option causes
command output to be suppressed until the command produces at least one
byte of output on stdout.
Environment
-----------
pwd is the project's working directory. If the current client is a
mirror client, then pwd is the Git repository.
REPO_PROJECT is set to the unique name of the project.
REPO_PATH is the path relative the the root of the client.
REPO_REMOTE is the name of the remote system from the manifest.
REPO_LREV is the name of the revision from the manifest, translated to a
local tracking branch. If you need to pass the manifest revision to a
locally executed git command, use REPO_LREV.
REPO_RREV is the name of the revision from the manifest, exactly as
written in the manifest.
REPO_COUNT is the total number of projects being iterated.
REPO_I is the current (1-based) iteration count. Can be used in
conjunction with REPO_COUNT to add a simple progress indicator to your
command.
REPO__* are any extra environment variables, specified by the
"annotation" element under any project element. This can be useful for
differentiating trees based on user-specific criteria, or simply
annotating tree details.
shell positional arguments ($1, $2, .., $#) are set to any arguments
following .
Unless -p is used, stdin, stdout, stderr are inherited from the terminal
and are not redirected.
If -e is used, when a command exits unsuccessfully, 'repo forall' will
abort without iterating through the remaining projects.
10. repo gitc-delete
$ repo help gitc-delete
Summary
-------
Delete a GITC Client.
Usage: repo gitc-delete
Options:
-h, --help show this help message and exit
-f, --force Force the deletion (no prompt).
Description
-----------
This subcommand deletes the current GITC client, deleting the GITC
manifest and all locally downloaded sources.
11. repo gitc-init
$ repo help gitc-init
Summary
-------
Initialize a GITC Client.
Usage: repo gitc-init [options] [client name]
Options:
-h, --help show this help message and exit
Logging options:
-q, --quiet be quiet
Manifest options:
-u URL, --manifest-url=URL

GITC options:
-f MANIFEST_FILE, --manifest-file=MANIFEST_FILE
Optional manifest file to use for this GITC client.
-c GITC_CLIENT, --gitc-client=GITC_CLIENT
The name of the gitc_client instance to create or
modify.
Description
-----------
The 'repo gitc-init' command is ran to initialize a new GITC client for
use with the GITC file system.
This command will setup the client directory, initialize repo, just like
repo init does, and then downloads the manifest collection and installs
it in the .repo/directory of the GITC client.
Once this is done, a GITC manifest is generated by pulling the HEAD SHA
for each project and generates the properly formatted XML file and
installs it as .manifest in the GITC client directory.
The -c argument is required to specify the GITC client name.
The optional -f argument can be used to specify the manifest file to use
for this GITC client.
12. repo grep
$ repo help grep

pattern to locate:
-e PATTERN
--and, --or, --not, -(, -)
Further, the -r/--revision option may be specified multiple times in
order to scan multiple trees. If the same file matches in more than one
tree, only the first result is reported, prefixed by the revision name
it was found under.
Examples
--------
Look for a line that has '#define' and either 'MAX_PATH or 'PATH_MAX':
repo grep -e '#define' --and -\( -e MAX_PATH -e PATH_MAX \)
Look for a line that has 'NODE' or 'Unexpected' in files that contain a
line that matches both expressions:
repo grep --all-match -e NODE -e Unexpected

branches
-o, --overview show overview of all local commits
-b, --current-branch consider only checked out branches
-l, --local-only Disable all remote operations
15. repo init
$ repo help init
Summary
-------
Initialize repo in the current directory
Usage: repo init [options]
Options:
-h, --help show this help message and exit

-p PLATFORM, --platform=PLATFORM
restrict manifest projects to ones with a specified
platform group [auto|all|none|linux|darwin|...]
--no-clone-bundle disable use of /clone.bundle on HTTP/HTTPS
repo Version options:
--repo-url=URL repo repository location
--repo-branch=REVISION
repo branch or revision
--no-repo-verify do not verify repo source code
Other options:
--config-name Always prompt for name/e-mail
Description
-----------
The 'repo init' command is run once to install and initialize repo. The
latest repo source code and manifest collection is downloaded from the
server and is installed in the .repo/ directory in the current working
directory.
The optional -b argument can be used to select the manifest branch to
checkout and use. If no branch is specified, master is assumed.
The optional -m argument can be used to specify an alternate manifest to
be used. If no manifest is specified, the manifest default.xml will be
used.
The --reference option can be used to point to a directory that has the
content of a --mirror sync. This will make the working directory use as
much data as possible from the local reference directory when fetching
from the server. This will make the sync go a lot faster by reducing
data traffic on the network.
The --no-clone-bundle option disables any attempt to use
$URL/clone.bundle to bootstrap a new Git repository from a resumeable
bundle file on a content delivery network. This may be necessary if
there are problems with the local Python HTTP client or proxy
configuration, but the Git binary works.
Switching Manifest Branches
---------------------------
To switch to another manifest branch, `repo init -b otherbranch` may be
used in an existing client. However, as this only updates the manifest,
a subsequent `repo sync` (or `repo sync -d`) is necessary to update the
working directory files.
16. repo list
$ repo help list
Summary
-------
List projects and their associated directories
Usage: repo list [-f] [...]
repo list [-f] -r str1 [str2]..."
Options:
-h, --help show this help message and exit
-r, --regex Filter the project list based on regex or wildcard
matching of strings
-g GROUPS, --groups=GROUPS
Filter the project list based on the groups the
project is in
-f, --fullpath Display the full work tree path instead of the
relative path
-n, --name-only Display only the name of the repository
-p, --path-only Display only the path of the repository
Description
-----------
List all projects; pass '.' to list the project for the cwd.
This is similar to running: repo forall -c 'echo "$REPO_PATH :
$REPO_PROJECT"'.
17. repo manifest
$ repo help manifest
Summary
-------
Manifest inspection utility
Usage: repo manifest [-o {-|NAME.xml} [-r]]
Options:
-h, --help show this help message and exit
-r, --revision-as-HEAD
Save revisions as current HEAD
--suppress-upstream-revision
If in -r mode, do not write the upstream field. Only
of use if the branch names for a sha1 manifest are
sensitive.
-o -|NAME.xml, --output-file=-|NAME.xml
File to save the manifest to
Description
-----------
With the -o option, exports the current manifest for inspection. The
manifest and (if present) local_manifest.xml are combined together to
produce a single manifest file. This file can be stored in a Git
repository for use during future 'repo init' invocations.
repo Manifest Format
====================
A repo manifest describes the structure of a repo client; that is the
directories that are visible and where they should be obtained from with
git.
The basic structure of a manifest is a bare Git repository holding a
single 'default.xml' XML file in the top level directory.
Manifests are inherently version controlled, since they are kept within
a Git repository. Updates to manifests are automatically obtained by
clients during `repo sync`.
XML File Format
---------------
A manifest XML file (e.g. 'default.xml') roughly conforms to the
following DTD:
]>
A description of the elements and their attributes follows.
Element manifest
----------------
The root element of the file.
Element remote
--------------
One or more remote elements may be specified. Each remote element
specifies a Git URL shared by one or more projects and (optionally) the
Gerrit review server those projects upload changes through.
Attribute `name`: A short name unique to this manifest file. The name
specified here is used as the remote name in each project's .git/config,
and is therefore automatically available to commands like `git fetch`,
`git remote`, `git pull` and `git push`.
Attribute `alias`: The alias, if specified, is used to override `name`
to be set as the remote name in each project's .git/config. Its value
can be duplicated while attribute `name` has to be unique in the
manifest file. This helps each project to be able to have same remote
name which actually points to different remote url.
Attribute `fetch`: The Git URL prefix for all projects which use this
remote. Each project's name is appended to this prefix to form the
actual URL used to clone the project.
Attribute `pushurl`: The Git "push" URL prefix for all projects which
use this remote. Each project's name is appended to this prefix to form
the actual URL used to "git push" the project. This attribute is
optional; if not specified then "git push" will use the same URL as the
`fetch` attribute.
Attribute `review`: Hostname of the Gerrit server where reviews are
uploaded to by `repo upload`. This attribute is optional; if not
specified then `repo upload` will not function.
Attribute `revision`: Name of a Git branch (e.g. `master` or
`refs/heads/master`). Remotes with their own revision will override the
default revision.
Element default
---------------
At most one default element may be specified. Its remote and revision
attributes are used when a project element does not specify its own
remote or revision attribute.
Attribute `remote`: Name of a previously defined remote element. Project
elements lacking a remote attribute of their own will use this remote.
Attribute `revision`: Name of a Git branch (e.g. `master` or
`refs/heads/master`). Project elements lacking their own revision
attribute will use this revision.
Attribute `dest-branch`: Name of a Git branch (e.g. `master`). Project
elements not setting their own `dest-branch` will inherit this value. If
this value is not set, projects will use `revision` by default instead.
Attribute `sync-j`: Number of parallel jobs to use when synching.
Attribute `sync-c`: Set to true to only sync the given Git branch
(specified in the `revision` attribute) rather than the whole ref space.
Project elements lacking a sync-c element of their own will use this
value.
Attribute `sync-s`: Set to true to also sync sub-projects.
Element manifest-server
-----------------------
At most one manifest-server may be specified. The url attribute is used
to specify the URL of a manifest server, which is an XML RPC service.
The manifest server should implement the following RPC methods:
GetApprovedManifest(branch, target)
Return a manifest in which each project is pegged to a known good
revision for the current branch and target. This is used by repo sync
when the --smart-sync option is given.
The target to use is defined by environment variables TARGET_PRODUCT and
TARGET_BUILD_VARIANT. These variables are used to create a string of the
form $TARGET_PRODUCT-$TARGET_BUILD_VARIANT, e.g. passion-userdebug. If
one of those variables or both are not present, the program will call
GetApprovedManifest without the target parameter and the manifest server
should choose a reasonable default target.
GetManifest(tag)
Return a manifest in which each project is pegged to the revision at the
specified tag. This is used by repo sync when the --smart-tag option is
given.
Element project
---------------
One or more project elements may be specified. Each element describes a
single Git repository to be cloned into the repo client workspace. You
may specify Git-submodules by creating a nested project. Git-submodules
will be automatically recognized and inherit their parent's attributes,
but those may be overridden by an explicitly specified project element.
Attribute `name`: A unique name for this project. The project's name is
appended onto its remote's fetch URL to generate the actual URL to
configure the Git remote with. The URL gets formed as:
${remote_fetch}/${project_name}.git
where ${remote_fetch} is the remote's fetch attribute and
${project_name} is the project's name attribute. The suffix ".git" is
always appended as repo assumes the upstream is a forest of bare Git
repositories. If the project has a parent element, its name will be
prefixed by the parent's.
The project name must match the name Gerrit knows, if Gerrit is being
used for code reviews.
Attribute `path`: An optional path relative to the top directory of the
repo client where the Git working directory for this project should be
placed. If not supplied the project name is used. If the project has a
parent element, its path will be prefixed by the parent's.
Attribute `remote`: Name of a previously defined remote element. If not
supplied the remote given by the default element is used.
Attribute `revision`: Name of the Git branch the manifest wants to track
for this project. Names can be relative to refs/heads (e.g. just
"master") or absolute (e.g. "refs/heads/master"). Tags and/or explicit
SHA-1s should work in theory, but have not been extensively tested. If
not supplied the revision given by the remote element is used if
applicable, else the default element is used.
Attribute `dest-branch`: Name of a Git branch (e.g. `master`). When
using `repo upload`, changes will be submitted for code review on this
branch. If unspecified both here and in the default element, `revision`
is used instead.
Attribute `groups`: List of groups to which this project belongs,
whitespace or comma separated. All projects belong to the group "all",
and each project automatically belongs to a group of its name:`name` and
path:`path`. E.g. for
Users may add projects to the local manifest(s) prior to a `repo sync`
invocation, instructing repo to automatically download and manage these
extra projects.
Manifest files stored in `$TOP_DIR/.repo/local_manifests/*.xml` will be
loaded in alphabetical order.
Additional remotes and projects may also be added through a local
manifest, stored in `$TOP_DIR/.repo/local_manifest.xml`. This method is
deprecated in favor of using multiple manifest files as mentioned above.
If `$TOP_DIR/.repo/local_manifest.xml` exists, it will be loaded before
any manifest files stored in `$TOP_DIR/.repo/local_manifests/*.xml`.
18. repo overview
$ repo help overview
Summary
-------
Display overview of unmerged project branches
Usage: repo overview [--current-branch] [...]
Options:
-h, --help show this help message and exit
-b, --current-branch Consider only checked out branches
Description
-----------
The 'repo overview' command is used to display an overview of the
projects branches, and list any local commits that have not yet been
merged into the project.
The -b/--current-branch option can be used to restrict the output to
only branches currently checked out in each project. By default, all
branches are displayed.
19. repo prune

-----------
'repo rebase' uses git rebase to move local changes in the current topic
branch to the HEAD of the upstream history, useful when you have made
commits in a topic branch but need to incorporate new upstream changes
"underneath" them.

Usage: repo stage -i [...]
Options:
-h, --help show this help message and exit
-i, --interactive use interactive staging
Description
-----------
The 'repo stage' command stages files to prepare the next commit.
24. repo start
$ repo help start
Summary
-------
Start a new branch for development
Usage: repo start [--all | ...]
Options:
-h, --help show this help message and exit
--all begin branch in all projects
Description
-----------
'repo start' begins a new branch of development, starting from the
revision specified in the manifest.
25. repo status
$ repo help status
Summary
-------
Show the working tree status
Usage: repo status [...]
Options:
-h, --help show this help message and exit
-j JOBS, --jobs=JOBS number of projects to check simultaneously
-o, --orphans include objects in working directory outside of repo
projects
Description
-----------
'repo status' compares the working tree to the staging area (aka index),
and the most recent commit on this branch (HEAD), in each project
specified. A summary is displayed, one line per file where there is a
difference between these three states.
The -j/--jobs option can be used to run multiple status queries in
parallel.
The -o/--orphans option can be used to show objects that are in the
working directory, but not associated with a repo project. This includes
unmanaged top-level files and directories, but also includes deeper
items. For example, if dir/subdir/proj1 and dir/subdir/proj2 are repo
projects, dir/subdir/proj3 will be shown if it is not known to repo.
Status Display
--------------
The status display is organized into three columns of information, for
example if the file 'subcmds/status.py' is modified in the project
'repo' on branch 'devwork':
project repo/ branch devwork
-m subcmds/status.py
The first column explains how the staging area (index) differs from the
last commit (HEAD). Its values are always displayed in upper case and
have the following meanings:
-: no difference
A: added (not in HEAD, in index )
M: modified ( in HEAD, in index, different content )
D: deleted ( in HEAD, not in index )
R: renamed (not in HEAD, in index, path changed )
C: copied (not in HEAD, in index, copied from another)
T: mode changed ( in HEAD, in index, same content )
U: unmerged; conflict resolution required
The second column explains how the working directory differs from the
index. Its values are always displayed in lower case and have the
following meanings:
-: new / unknown (not in index, in work tree )
m: modified ( in index, in work tree, modified )
d: deleted ( in index, not in work tree )
26. repo sync
$ repo help sync
Summary
-------

Usage: repo sync [...]
Options:
-h, --help show this help message and exit
-f, --force-broken continue sync even if a project fails to sync
--force-sync overwrite an existing git directory if it needs to
point to a different object directory. WARNING: this
may cause loss of data
-l, --local-only only update working tree, don't fetch
-n, --network-only fetch only, don't update working tree
-d, --detach detach projects back to manifest revision
-c, --current-branch fetch only current branch from server
-q, --quiet be more quiet
-j JOBS, --jobs=JOBS projects to fetch simultaneously (default 1)

-u MANIFEST_SERVER_USERNAME, --manifest-server-username=MANIFEST_SERVER_USERNAME
username to authenticate with the manifest server
-p MANIFEST_SERVER_PASSWORD, --manifest-server-password=MANIFEST_SERVER_PASSWORD
password to authenticate with the manifest server
--fetch-submodules fetch submodules from server
--no-tags don't fetch tags
--optimized-fetch only fetch projects fixed to sha1 if revision does not
exist locally
--prune delete refs that no longer exist on the remote
-s, --smart-sync smart sync using manifest from the latest known good
build
-t SMART_TAG, --smart-tag=SMART_TAG
smart sync using manifest from a known tag
repo Version options:
--no-repo-verify do not verify repo source code
Description
-----------
The 'repo sync' command synchronizes local project directories with the
remote repositories specified in the manifest. If a local project does
not yet exist, it will clone a new local directory from the remote
repository and set up tracking branches as specified in the manifest. If
the local project already exists, 'repo sync' will update the remote
branches and rebase any new local changes on top of the new remote
changes.
'repo sync' will synchronize all projects listed at the command line.
Projects can be specified either by name, or by a relative or absolute
path to the project's local directory. If no projects are specified,
'repo sync' will synchronize all projects listed in the manifest.
The -d/--detach option can be used to switch specified projects back to
the manifest revision. This option is especially helpful if the project
is currently on a topic branch, but the manifest revision is temporarily
needed.
The -s/--smart-sync option can be used to sync to a known good build as
specified by the manifest-server element in the current manifest. The
-t/--smart-tag option is similar and allows you to specify a custom
tag/label.
The -u/--manifest-server-username and -p/--manifest-server-password
options can be used to specify a username and password to authenticate
with the manifest server when using the -s or -t option.
If -u and -p are not specified when using the -s or -t option, 'repo
sync' will attempt to read authentication credentials for the manifest
server from the user's .netrc file.
'repo sync' will not use authentication credentials from -u/-p or .netrc
if the manifest server specified in the manifest file already includes
credentials.
The -f/--force-broken option can be used to proceed with syncing other
projects if a project sync fails.
The --force-sync option can be used to overwrite existing git
directories if they have previously been linked to a different object
direcotry. WARNING: This may cause data to be lost since refs may be
removed when overwriting.
The --no-clone-bundle option disables any attempt to use
$URL/clone.bundle to bootstrap a new Git repository from a resumeable
bundle file on a content delivery network. This may be necessary if
there are problems with the local Python HTTP client or proxy
configuration, but the Git binary works.
The --fetch-submodules option enables fetching Git submodules of a
project from server.
The -c/--current-branch option can be used to only fetch objects that
are on the branch specified by a project's revision.
The --optimized-fetch option can be used to only fetch projects that are
fixed to a sha1 revision if the sha1 revision does not already exist
locally.
The --prune option can be used to remove any refs that no longer exist
on the remote.
SSH Connections
---------------
If at least one project remote URL uses an SSH connection (ssh://,
git+ssh://, or user@host:path syntax) repo will automatically enable the
SSH ControlMaster option when connecting to that host. This feature
permits other projects in the same 'repo sync' session to reuse the same
SSH tunnel, saving connection setup overheads.
To disable this behavior on UNIX platforms, set the GIT_SSH environment
variable to 'ssh'. For example:
export GIT_SSH=ssh
repo sync
Compatibility
~~~~~~~~~~~~~
This feature is automatically disabled on Windows, due to the lack of
UNIX domain socket support.
This feature is not compatible with url.insteadof rewrites in the user's
~/.gitconfig. 'repo sync' is currently not able to perform the rewrite
early enough to establish the ControlMaster tunnel.
If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or later
is required to fix a server side protocol bug.
27. repo upload
$ repo help upload
Summary
-------
Upload changes for code review
Usage: repo upload [--re --cc] []...
Options:
-h, --help show this help message and exit
-t Send local branch name to Gerrit Code Review
--re=REVIEWERS, --reviewers=REVIEWERS
Request reviews from these people.
--cc=CC Also send email to these email addresses.
--br=BRANCH Branch to upload.
--cbr, --current-branch
Upload current git branch.
-d, --draft If specified, upload as a draft.
-D BRANCH, --destination=BRANCH, --dest=BRANCH
Submit for review on this target branch.
--no-verify Do not run the upload hook.
--verify Run the upload hook without prompting.
Description
-----------
The 'repo upload' command is used to send changes to the Gerrit Code
Review system. It searches for topic branches in local projects that
have not yet been published for review. If multiple topic branches are
found, 'repo upload' opens an editor to allow the user to select which
branches to upload.
'repo upload' searches for uploadable changes in all projects listed at
the command line. Projects can be specified either by name, or by a
relative or absolute path to the project's local directory. If no
projects are specified, 'repo upload' will search for uploadable changes
in all projects listed in the manifest.
If the --reviewers or --cc options are passed, those emails are added to
the respective list of users, and emails are sent to any new users.
Users passed as --reviewers must already be registered with the code
review system, or the upload will fail.
Configuration
-------------
review.URL.autoupload:
To disable the "Upload ... (y/N)?" prompt, you can set a per-project or
global Git configuration option. If review.URL.autoupload is set to
"true" then repo will assume you always answer "y" at the prompt, and
will not prompt you further. If it is set to "false" then repo will
assume you always answer "n", and will abort.
review.URL.autoreviewer:
To automatically append a user or mailing list to reviews, you can set a
per-project or global Git option to do so.
review.URL.autocopy:
To automatically copy a user or mailing list to all uploaded reviews,
you can set a per-project or global Git option to do so. Specifically,
review.URL.autocopy can be set to a comma separated list of reviewers
who you always want copied on all uploads with a non-empty --re
argument.
review.URL.username:
Override the username used to connect to Gerrit Code Review. By default
the local part of the email address is used.
The URL must match the review URL listed in the manifest XML file, or in
the .git/config within the project. For example:
[remote "origin"]
url = git://git.example.com/project.git
review = http://review.example.com/
[review "http://review.example.com/"]
autoupload = true
autocopy = [email protected],[email protected]
review.URL.uploadtopic:
To add a topic branch whenever uploading a commit, you can set a
per-project or global Git option to do so. If review.URL.uploadtopic is
set to "true" then repo will assume you always want the equivalent of
the -t option to the repo command. If unset or set to "false" then repo
will make use of only the command line option.
