'''A tool that builds RC files and resource header files for compilation.
Usage: grit build [-o OUTPUTDIR] [-D NAME[=VAL]]*
All output options for this tool are specified in the input file (see
'grit help' for details on how to specify the input file - it is a global
option).
Options:
-a FILE Assert that the given file is an output. There can be
multiple "-a" flags listed for multiple outputs. If a "-a"
or "--assert-file-list" argument is present, then the list
of asserted files must match the output files or the tool
will fail. The use-case is for the build system to maintain
separate lists of output files and to catch errors if the
build system's list and the grit list are out-of-sync.
--assert-file-list Provide a file listing multiple asserted output files.
There is one file name per line. This acts like specifying
each file with "-a" on the command line, but without the
possibility of running into OS line-length limits for very
long lists.
-o OUTPUTDIR Specify what directory output paths are relative to.
Defaults to the current directory.
-D NAME[=VAL] Specify a C-preprocessor-like define NAME with optional
value VAL (defaults to 1) which will be used to control
conditional inclusion of resources.
-E NAME=VALUE Set environment variable NAME to VALUE (within grit).
-f FIRSTIDSFILE Path to a python file that specifies the first id of
value to use for resources. A non-empty value here will
override the value specified in the <grit> node's
first_ids_file.
-w WHITELISTFILE Path to a file containing the string names of the
resources to include. Anything not listed is dropped.
-t PLATFORM Specifies the platform the build is targeting; defaults
to the value of sys.platform. The value provided via this
flag should match what sys.platform would report for your
target platform; see grit.node.base.EvaluateCondition.
-h HEADERFORMAT Custom format string to use for generating rc header files.
The string should have two placeholders: {textual_id}
and {numeric_id}. E.g. "#define {textual_id} {numeric_id}"
Otherwise it will use the default "#define SYMBOL 1234"
--output-all-resource-defines
--no-output-all-resource-defines If specified, overrides the value of the
output_all_resource_defines attribute of the root <grit>
element of the input .grd file.
--write-only-new flag
If flag is non-0, write output files to a temporary file
first, and copy it to the real output only if the new file
is different from the old file. This allows some build
systems to realize that dependent build steps might be
unnecessary, at the cost of comparing the output data at
grit time.
--depend-on-stamp
If specified along with --depfile and --depdir, the depfile
generated will depend on a stampfile instead of the first
output in the input .grd file.
Conditional inclusion of resources only affects the output of files which
control which resources get linked into a binary, e.g. it affects .rc files
meant for compilation but it does not affect resource header files (that define
IDs). This helps ensure that values of IDs stay the same, that all messages
are exported to translation interchange files (e.g. XMB files), etc.

'''class for running bader analysis and extracting data from it.
The class runs bader, extracts the charge density and outputs it
to a cube file. Then you call different functions of the class to
extract the charges, volumes, etc...
ACF.dat contains the coordinates of each atom, the charge
associated with it according to Bader partitioning, percentage of
the whole according to Bader partitioning and the minimum distance
to the surface. This distance should be compared to maximum
cut-off radius for the core region if pseudo potentials have been
used.
BCF.dat contains the coordinates of each Bader maxima, the charge
within that volume, the nearest atom and the distance to that
atom.
AtomVolumes.dat contains the number of each volume that has been
assigned to each atom. These numbers correspond to the number of
the BvAtxxxx.dat files.
The options for the executable are::
bader [ -c bader | voronoi ]
[ -n bader | voronoi ]
[ -b neargrid | ongrid ]
[ -r refine_edge_iterations ]
[ -ref reference_charge ]

# acl.py - changeset access control for mercurial
#
# Copyright 2006 Vadim Gelfer <[email protected]>
#
# This software may be used and distributed according to the terms of the
# GNU General Public License version 2 or any later version.
'''hooks for controlling repository access
This hook makes it possible to allow or deny write access to given
branches and paths of a repository when receiving incoming changesets
via pretxnchangegroup and pretxncommit.
The authorization is matched based on the local user name on the
system where the hook runs, and not the committer of the original
changeset (since the latter is merely informative).
The acl hook is best used along with a restricted shell like hgsh,
preventing authenticating users from doing anything other than pushing
or pulling. The hook is not safe to use if users have interactive
shell access, as they can then disable the hook. Nor is it safe if
remote users share an account, because then there is no way to
distinguish them.
The order in which access checks are performed is:
1) Deny list for branches (section ``acl.deny.branches``)
2) Allow list for branches (section ``acl.allow.branches``)
3) Deny list for paths (section ``acl.deny``)
4) Allow list for paths (section ``acl.allow``)
The allow and deny sections take key-value pairs.
Branch-based Access Control
---------------------------
Use the ``acl.deny.branches`` and ``acl.allow.branches`` sections to
have branch-based access control. Keys in these sections can be
either:
- a branch name, or
- an asterisk, to match any branch;
The corresponding values can be either:
- a comma-separated list containing users and groups, or
- an asterisk, to match anyone;
You can add the "!" prefix to a user or group name to invert the sense
of the match.
Path-based Access Control
-------------------------
Use the ``acl.deny`` and ``acl.allow`` sections to have path-based
access control. Keys in these sections accept a subtree pattern (with
a glob syntax by default). The corresponding values follow the same
syntax as the other sections above.
Groups
------
Group names must be prefixed with an ``@`` symbol. Specifying a group
name has the same effect as specifying all the users in that group.
You can define group members in the ``acl.groups`` section.
If a group name is not defined there, and Mercurial is running under
a Unix-like system, the list of users will be taken from the OS.
Otherwise, an exception will be raised.
Example Configuration
---------------------
::
[hooks]
# Use this if you want to check access restrictions at commit time
pretxncommit.acl = python:hgext.acl.hook
# Use this if you want to check access restrictions for pull, push,
# bundle and serve.
pretxnchangegroup.acl = python:hgext.acl.hook
[acl]
# Allow or deny access for incoming changes only if their source is
# listed here, let them pass otherwise. Source is "serve" for all
# remote access (http or ssh), "push", "pull" or "bundle" when the
# related commands are run locally.
# Default: serve
sources = serve
[acl.deny.branches]
# Everyone is denied to the frozen branch:
frozen-branch = *
# A bad user is denied on all branches:
* = bad-user
[acl.allow.branches]
# A few users are allowed on branch-a:
branch-a = user-1, user-2, user-3
# Only one user is allowed on branch-b:
branch-b = user-1
# The super user is allowed on any branch:
* = super-user
# Everyone is allowed on branch-for-tests:
branch-for-tests = *
[acl.deny]
# This list is checked first. If a match is found, acl.allow is not
# checked. All users are granted access if acl.deny is not present.
# Format for both lists: glob pattern = user, ..., @group, ...
# To match everyone, use an asterisk for the user:
# my/glob/pattern = *
# user6 will not have write access to any file:
** = user6
# Group "hg-denied" will not have write access to any file:
** = @hg-denied
# Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
# everyone being able to change all other files. See below.
src/main/resources/DONT-TOUCH-THIS.txt = *
[acl.allow]
# if acl.allow is not present, all users are allowed by default
# empty acl.allow = no users allowed
# User "doc_writer" has write access to any file under the "docs"
# folder:
docs/** = doc_writer
# User "jack" and group "designers" have write access to any file
# under the "images" folder:
images/** = jack, @designers
# Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
# will have write access to any file under the "resources" folder
# (except for 1 file. See acl.deny):
src/main/resources/** = *
.hgtags = release_engineer
Examples using the "!" prefix
.............................
Suppose there's a branch that only a given user (or group) should be able to
push to, and you don't want to restrict access to any other branch that may
be created.
The "!" prefix allows you to prevent anyone except a given user or group to
push changesets in a given branch or path.
In the examples below, we will:
1) Deny access to branch "ring" to anyone but user "gollum"
2) Deny access to branch "lake" to anyone but members of the group "hobbit"
3) Deny access to a file to anyone but user "gollum"
::
[acl.allow.branches]
# Empty
[acl.deny.branches]
# 1) only 'gollum' can commit to branch 'ring';
# 'gollum' and anyone else can still commit to any other branch.
ring = !gollum
# 2) only members of the group 'hobbit' can commit to branch 'lake';
# 'hobbit' members and anyone else can still commit to any other branch.
lake = !@hobbit
# You can also deny access based on file paths:
[acl.allow]
# Empty
[acl.deny]
# 3) only 'gollum' can change the file below;
# 'gollum' and anyone else can still change any other file.
/misty/mountains/cave/ring = !gollum
