This subdirectory contains option (flag) names and descriptions
common to multiple podman man pages. Each file is one option. The
filename does not necessarily need to be identical to the option
name: for instance, hostname.container.md and hostname.pod.md
exist because the --hostname option is sufficiently different
between podman-{create,run} and podman-pod-{create,run} to
warrant living separately.
How
The files here are included in podman-*.md.in files using the @@option
mechanism:
@@option foo ! includes options/foo.md
The tool that does this is hack/markdown-preprocess. It is a python
script because it needs to run on readthedocs.io. From a given .md.in
file, this script creates a .md file that can then be read by
go-md2man, sphinx, anything that groks markdown. This runs as
part of make docs.
Special Substitutions
Some options are almost identical except for 'pod' vs 'container'
differences. For those, use <<text for pods|text for containers>>.
Order is immaterial: the important thing is the presence of the
string "pod" in one half but not the other. The correct string
is chosen based on the filename: if the file contains -pod,
such as podman-pod-create, the string with pod (case-insensitive)
in it is chosen.
The string <<subcommand>> is replaced with the podman subcommand
as determined from the filename, e.g., create for podman-create.1.md.in.
This allows the shared use of examples in the option file:
Example: podman <<subcommand>> --foo --bar
As a special case, podman-pod-X becomes just X (the "pod" is removed).
This makes the pod-id-file man page more useful. To get the full
subcommand including 'pod', use <<fullsubcommand>>.
Restrictions
There is a restriction for having a single text line with three
back-ticks in the front and the end of the line. For instance:
```Some man page text```
This is currently not allowed and causes a corruption of the
compiled man page. Instead, put the three back-ticks on separate
lines like:
