LEI-P2Q(1)                 public-inbox user manual                 LEI-P2Q(1)

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
