# Programmable completion for the Subversion svn command under bash. Source

# commands as well.  Who wants to read man pages/help text...

# Known to work with bash 3.* with programmable completion and extended
# pattern matching enabled (use 'shopt -s extglob progcomp' to enable
# these if they are not already enabled).

# This completion guides the command/option order along the one suggested
# by "svn help", although other syntaxes are allowed.
#
# - there is a "real" parser to check for what is available and deduce what
#   can be suggested further.
# - the syntax should be coherent with subversion/svn/{cl.h,main.c}
# - although it is not a good practice, mixed options and arguments
#   is supported by the completion as it is by the svn command.
# - the completion works in the middle of a line,
#   but not really in the middle of an argument or option.
# - property names are completed: see comments about issues related to handling
#   ":" within property names although it is a word completion separator.
# - unknown properties are assumed to be simple file properties.
# - --revprop and --revision options are forced to revision properties
#   as they are mandatory in this case.
# - argument values are suggested to some other options, eg directory names
#   for --config-dir.
# - values for some options can be extended with environment variables:
#   SVN_BASH_FILE_PROPS: other properties on files/directories
#   SVN_BASH_REV_PROPS: other properties on revisions
#   SVN_BASH_ENCODINGS: encodings to be suggested
#   SVN_BASH_MIME_TYPE: mime types to be suggested
#   SVN_BASH_KEYWORDS: "svn:keywords" substitutions to be suggested
#   SVN_BASH_USERNAME: usernames suggested for --username
#   SVN_BASH_COMPL_EXT: completion extensions for file arguments, based on the
#      current subcommand, so that for instance only modified files are
#      suggested for 'revert', only not svn-managed files for 'add', and so on.
#      Possible values are:
#      - username: guess usernames from ~/.subversion/auth/...
#      - urls: guess urls from ~/.subversion/auth/... or others
#      - svnstatus: use 'svn status' for completion
#      - recurse: allow recursion (expensive)
#      - externals: recurse into externals (very expensive)
#     Former options are reasonable, but beware that both later options
#     may be unadvisable if used on large working copies.
#     None of these costly completions are activated by default.
#     Argument completion outside a working copy results in an error message.
#     Filenames with spaces are not completed properly.
#
# TODO
# - other options?
# - obsolete options could be removed from auto-comp? (e.g. -N)
# - obsolete commands could be removed? (e.g. resolved)
# - completion does not work properly when editing in the middle of the line
#   status/previous are those at the end of the line, not at the entry position
# - url completion should select more cases where it is relevant
# - url completion of http:// schemas could suggest sub directories?
# - add completion for experimental 'obliterate' feature?
