NAME

       lei-p2q - use a patch to generate a lei-q query

SYNOPSIS

       lei p2q [OPTIONS] (FILE|COMMIT)

       lei p2q [OPTIONS] (--stdin|-)

DESCRIPTION

       Given a patch, create a query that can be fed on stdin to lei-q(1).  This is useful for
       mapping the patch to associated messages of an inbox.

       The patch can be provided on stdin or as a file.  Alternatively, when an argument is given
       that does not point to an existing file, it is taken as a reference to a commit in the
       current git repository, and git-format-patch(1) is used to generate the patch.

OPTIONS

       -w PREFIX[,PREFIX]
       --want=PREFIX[,PREFIX]
           Search prefixes to use.  "dfpost" (post-image git blob ID) and "dfn" (file names from
           the diff) are the most useful.  Other available values are "dfa", "dfb", "dfctx",
           "dfhh", and "dfpre".

           Appending an integer to "dfpost" or "dfpre" indicates a minimum ID length, and the
           generated query will be for that value up through the default abbreviation length.
           For example, if the repository's "core.abbrev" is set to "auto" and git calculates the
           default abbreviation length as 7, "dfpost6" will expand a post-image blob ID of
           e7b4b32 (seven characters) into "dfpost:e7b4b32 OR dfpost:e7b4b3".

           This option may be given multiple times.

           Default: "dfpost7"

       --stdin
           Read message from stdin.  This is implicit if no arguments are given and stdin is a
           pipe or regular file.

       --debug
           Dump output that shows the information collected for every prefix.  This information
           can be useful for seeing how a patch is processed, but the format should not be
           considered stable.

       --uri
           URI escape output for interacting with HTTP(S) public-inbox instances.

       -q
       --quiet
           Suppress feedback messages.

EXAMPLES

         # to search for all threads which touch a given thread:
         lei p2q $COMMIT_OID | lei q -t -o /tmp/results

         # to view results on a remote HTTP(S) public-inbox instance
         $BROWSER https://example.com/pub-inbox/?q=$(lei p2q --uri $COMMIT_OID)

         # to view unapplied patches for a given $FILE from the past year:
         echo \( rt:last.year.. AND dfn:$FILE \) AND NOT \( \
               $(git log -p --pretty=mboxrd --since=last.year $FILE |
                       lei p2q -F mboxrd )
               \) | lei q -o /tmp/unapplied
