The current help output might change based on the number of CPU cores available (since it reflects the dynamic --jobs logic). This is good for users running repo locally, but not good for shipping static man pages. Hook the help output to have it generate the same output all the time.

.SH DETAILS
|
|
.PP
|
|
Executes the same shell command in each project.
|
|
.PP
|
|
The \fB\-r\fR option allows running the command only on projects matching regex or
|
|
wildcard expression.
|
|
.PP
|
|
By default, projects are processed non\-interactively in parallel. If you want to
|
|
run interactive commands, make sure to pass \fB\-\-interactive\fR to force \fB\-\-jobs\fR 1.
|
|
While the processing order of projects is not guaranteed, the order of project
|
|
output is stable.
|
|
.PP
|
|
Output Formatting
|
|
.PP
|
|
The \fB\-p\fR 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.
|
|
.PP
|
|
The formatting convention used by \fB\-p\fR is very suitable for some types of
|
|
searching, e.g. `repo forall \fB\-p\fR \fB\-c\fR git log \fB\-SFoo\fR` will print all commits that
|
|
add or remove references to Foo.
|
|
.PP
|
|
The \fB\-v\fR option causes 'repo forall' to display stderr messages if a command
|
|
produces output only on stderr. Normally the \fB\-p\fR option causes command output to
|
|
be suppressed until the command produces at least one byte of output on stdout.
|
|
.PP
|
|
Environment
|
|
.PP
|
|
pwd is the project's working directory. If the current client is a mirror
|
|
client, then pwd is the Git repository.
|
|
.PP
|
|
REPO_PROJECT is set to the unique name of the project.
|
|
.PP
|
|
REPO_PATH is the path relative the the root of the client.
|
|
.PP
|
|
REPO_REMOTE is the name of the remote system from the manifest.
|
|
.PP
|
|
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.
|
|
.PP
|
|
REPO_RREV is the name of the revision from the manifest, exactly as written in
|
|
the manifest.
|
|
.PP
|
|
REPO_COUNT is the total number of projects being iterated.
|
|
.PP
|
|
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.
|
|
.PP
|
|
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.
|
|
.PP
|
|
shell positional arguments ($1, $2, .., $#) are set to any arguments following
|
|
<command>.
|
|
.PP
|
|
Example: to list projects:
|
|
.IP
|
|
repo forall \fB\-c\fR 'echo $REPO_PROJECT'
|
|
.PP
|
|
Notice that $REPO_PROJECT is quoted to ensure it is expanded in the context of
|
|
running <command> instead of in the calling shell.
|
|
.PP
|
|
Unless \fB\-p\fR is used, stdin, stdout, stderr are inherited from the terminal and are
|
|
not redirected.
|
|
.PP
|
|
If \fB\-e\fR is used, when a command exits unsuccessfully, 'repo forall' will abort
|
|
without iterating through the remaining projects.
