Add initial hook support
This adds the basic hook code as well as pre and post-commit hooks.
Argument passing is by environment variable key/value pairs so that
extra data can be passed over time. File lists will generally not be
passed to hooks as these can be extremely long (>1M).

NAME
----
hg - Mercurial source code management system
SYNOPSIS
--------
'hg' [-v -d -q -y] <command> [command options] [files]
DESCRIPTION
-----------
The hg(1) command provides a command line interface to the Mercurial system.
OPTIONS
-------
--debug, -d::
enable debugging output
--quiet, -q::
suppress output
--verbose, -v::
enable additional output
--noninteractive, -y::
do not prompt, assume 'yes' for any required answers
COMMAND ELEMENTS
----------------
files ...::
indicates one or more filename or relative path filenames
path::
indicates a path on the local machine
revision::
indicates a changeset which can be specified as a changeset revision
number, a tag, or a unique substring of the changeset hash value
repository path::
is either the pathname of a local repository of the URI of a remote
repository. There are two available URI protocols, http:// which is
fast and the old-http:// protocol which is much slower but does not
require a special server on the web host.
COMMANDS
--------
add [files ...]::
Add the given files to the repository. Note that this just schedules the
files for addition at the next hg commit time.
addremove::
Add all new files and remove all missing files from the repository. New
files are ignored if they match any of the patterns in .hgignore
annotate [-r <rev> -u -n -c] [files ...]::
List the files with each line showing the revision id responsible
for that line.
options:
-r, --revision <rev> annotate the specified revision
-u, --user list the author
-c, --changeset list the changeset
-n, --number list the revision number (default)
cat <file> [revision]::
Output the given revision or tip of the specified file to stdout.
clone [-U] <source> [dest]::
Create a new copy of an existing repository.
If the specified source is on the same filesystem, the repository
will be copied via hardlinks. This is the fastest and most
space-efficient mode of operation.
If the destination directory is not specified, it defaults to the
current directory.
If the destination is specified, but does not exist, it is created.
The source is added to .hg/hgrc in the new copy as the default for
future pulls.
options:
-U, --no-update do not update the new working directory
commit [-A -t -l <file> -t <text> -u <user> -d <datecode>] [files...]::
Commit all changed files in the working dir to the repository. This uses
the EDITOR environment variable to bring up an editor to add a commit
comment.
Options:
-A, --addremove run addremove during commit
-t, --text <text> use <text> as commit message
-l, --logfile <file> read the commit message from the specified
file
-d, --date <datecode> use the specified date code
-u, --user <user> record commit as the specified user
aliases: ci
copy <source> <dest>::
Mark a file as copied or renamed for the next commit.
diff [-r revision] [-r revision] [files ...]::
Generate a unified diff of the indicated files. If there are no
revisions specified, the working directory file is compared to
the tip, one revision specified indicates a comparison between the
working directory file and the specified revision, and two revisions
compares the two versions specified.
export [revision]::
Print the changeset header (author, changeset hash, parent, and commit
comment) and the diffs for a particular revision.
forget [files]::
Undo an 'hg add' scheduled for the next commit.
heads::
Show all changesets with no children. These are the "heads" of
development branches and are the usual targets for updates and merges.
history::
Print the revision history of the repository. Use the -v switch
for more detail.
identify::
Print a short identifier of the current state of the repo. This
includes one or two parent hash identifiers, followed by
a "+" if there are uncommitted changes in the working directory,
followed by a list of tags for this revision.
aliases: id
import [-p <n> -b <base> -q] <patches>::
Import the listed patches and commit them individually.
options:
-p, --strip <n> directory strip option for patch
-b <path> base directory to read patches from
aliases: patch
init [-u] [source]::
Initialize a repository in the current directory.
NOTE: The following use is deprecated, and will be removed soon;
use the "hg clone" command instead.
If a source is specified, pull that source into the repository.
This source is added to .hg/hgrc as the default for future pulls
in this repository.
If the specified source is on the same filesystem, the repository
will be copied via hardlinks. This is the fastest and most
space-efficient mode of operation.
options:
-u, --update update the working directory to match the tip
log <file>::
Print the revision history of the specified file.
manifest [revision]::
Print the indicated revision of the manifest (list of version controlled
files).
parents::
Print the working directory's parent revisions.
pull <repository path>::
Pull any changes from the specified repository to the repository in the
current directory.
options:
-u, --update update the working directory to tip after pull
push <destination>::
Push changes from the local repository to the specified
destination. If the destination is local, this is identical to a
a pull in that directory from the current directory.
The other currently available push method is SSH. This requires an
accessible shell account on the destination machine and a copy of
hg in the remote path. Destinations are specified in the following
form:
ssh://[user@]host[:port]/path
rawcommit [-p -d -u -F -t -l]::
Primarily useful for importing from other SCMs.
recover::
Recover from an interrupted commit or pull. This should only be
necessary when Mercurial suggests it.
remove [files ...]::
Schedule the indicated files for removal from the repository at the next
commit.
aliases: rm
root::
Print the root directory of the current repository.
serve [-a addr -n name -p port -t templatedir]::
Start a local HTTP repository browser and pull server.
options:
-a, --address <addr> address to use
-p, --port <n> port to use (default: 8000)
-n, --name <name> name to show in web pages (default: working dir)
-t, --templatedir <path> web templates to use
status::
Show changed files in the working directory.
C = changed
A = added
R = removed
? = not tracked
tag [-t <text> -d <datecode> -u <user>] <name> [revision]::
Add a tag <name> to the specified revision or the tip.
options:
-t, --text <text> message for tag commit log entry
-d, --date <datecode> datecode for commit
-u, --user <user> user for commit
tags::
List the repository tags.
tip::
Show the tip revision.
undo::
Undo the last commit or pull transaction.
update [-m -C] [revision]::
Update or merge the working directory to a specified revision.
If there are no outstanding changes in the working directory and
there is a linear relationship between the current version and the
requested version, the result is the requested version.
Otherwise the result is a merge between the contents of the
current working directory and the requested version. Files that
changed between either parent are marked as changed for the next
commit and a commit must be performed before any further updates
are allowed. Merging will not be performed without the -m flag.
The -C switch will tell Mercurial to forcibly update to the
specified version, adding, removing, and overwriting locally
changed fils as necessary.
options:
-m, --merge allow merging of branches
-C, --clean overwrite locally modified files
aliases: up checkout co
verify::
Verify the integrity of the current repository.
This will perform an extensive check of the repository's
integrity, validating the hashes and checksums of each entry in
the changelog, manifest, and tracked files, as well as the
integrity of their crosslinks and indices.
ENVIRONMENT VARIABLES
---------------------
HGEDITOR::
This is the name of the editor to use when committing. Defaults to the
value of EDITOR.
HGMERGE::
An executable to use for resolving merge conflicts. The program ,
will be executed with three arguments: local file, remote file,
ancestor file.
The default program is "hgmerge", which is a shell script provided
by Mercurial with some sensible defaults.
HGUSER::
This is the string used for the author of a commit.
EMAIL::
If HGUSER is not set, this will be used as the author for a commit.
LOGNAME::
If neither HGUSER nor EMAIL is set, LOGNAME will be used (with
'@hostname' appended) as the author value for a commit.
EDITOR::
This is the name of the editor used in the hgmerge script. It will be
used for commit messages, too, if HGEDITOR isn't set. Defaults to 'vi'.
PYTHONPATH::
This is used by Python to find imported modules and may need to be set
appropriately if Mercurial is not installed system-wide.
FILES
-----
.hgignore::
This file contains regular expressions (one per line) that describe file
names that should be ignored by hg.
.hgtags::
This file contains changeset hash values and text tag names (one of each
seperated by spaces) that correspond to tagged versions of the repository
contents.
$HOME/.hgrc, .hg/hgrc::
This file contains defaults and configuration. Values in .hg/hgrc
override those in .hgrc.
NAMED REPOSITORIES
------------------
To give symbolic names to a repository, create a section in .hgrc
or .hg/hgrc containing assignments of names to paths. Example:
-----------------
[paths]
hg = http://selenic.com/hg
tah = http://hg.intevation.org/mercurial-tah/
-----------------
HOOKS
-----
Mercurial supports a set of 'hook', commands that get automatically
executed by various actions such as starting or finishing a commit. To
specify a hook, simply create an hgrc section like the following:
-----------------
[hooks]
precommit = echo "this hook gets executed immediately before a commit"
commit = hg export $NODE | mail -s "new commit $NODE" commit-list
-----------------
NON_TRANSPARENT PROXY SUPPORT
-----------------------------
To access a Mercurial repository through a proxy, create a file
$HOME/.hgrc in the following format:
--------------
[http_proxy]
host=myproxy:8080
user=<username>
passwd=<password>
no=<localhost1>,<localhost2>,<localhost3>,...
--------------
"user","passwd" fields are used for authenticating proxies, "no" is a
comma-separated list of local host names for which proxy must be
bypassed.
BUGS
----
Probably lots, please post them to the mailing list (See Resources below)
when you find them.
