Josh's SVN wrapper script
https://github.com/holtrop/jsvn
This wrapper script to Subversion supplements normal svn behavior by
adding additional functionality or modifying the output of the default
svn subcommands (simplification and colorization). Much of the functionality
implemented here was inspired by the way that git works.
It is recommended to put this script in your $PATH as 'jsvn' or something
other than 'svn' and to make an alias svn='jsvn'.
For example, this .bash_aliases stanza will check if 'jsvn' is in your
path and automatically alias 'svn' to it if so:
if [[ "$(which jsvn 2>/dev/null)" != "" ]]; then
alias svn='jsvn'
fi
Implemented subcommands:
add <file>...
- add files as usual; add recursive contents of directories
binaries [--set-lock]
- show a list of versioned binary files under the current path, with
a prepended '*' for those with svn:needs-lock set
- with --set-lock, set svn:needs-lock to '*' for binaries
bisect <operation>
operations:
- init initialize a new bisect operation
- bad mark the current revision as bad - containing the change sought
- good mark the current revision as good - older than the change sought
- reset terminate the bisect operation and return to the original revision
branch[es] [-d] [-s] [<branch_name>]
- with no arguments, list branches with '*' by the current one
- with -d, delete <branch>
- otherwise, create a new branch from the current one
- also switch to the new branch if -s is given
diff
- allow specifying ref1..ref2 syntax to show the diff between two references
- references can be tag names, branch names, or 'trunk'
- allow specifying ref1...ref2 syntax to show the diff between the common
ancestor of ref1 and ref2 and ref2's HEAD
externals
- print a list of the externals in the repository
lockable [--remove] | [--status] <file[s]>
- with no switches, set svn:needs-lock to '*' for file[s]
- with --remove, remove svn:needs-lock' for file[s]
- with --status, prepended '*' for those with svn:needs-lock set
log
- allow specifying ref1..ref2 syntax to show the log entries for
ref2 which are not a part of ref1
merge <branch>
- merge branch <branch> into the current WC path
- falls back to Subversion "merge" if <branch> doesn't exist
root
- output root URL (for use on shell such as "svn log $(svn root)/tags")
stash [command]
- allow temporarily saving changes to the working copy without committing
- the stashes behaves as a "stack" where "save" pushes a new stash object
and "pop" pops the newest one from the top of the stack
commands:
save [-k] (default if not specified):
- save changes as a "stash" object
- revert changes from working copy unless -k (keep working copy) given
- this only works with text files, not binary files
list:
- show a list of all stash objects
pop [-k] [id]:
- apply the stash object <id> back to the working copy
- the stash object is removed unless -k (keep) given
- <id> defaults to the newest stash object created
show [id]:
- display the diff stored in stash with ID <id>
- <id> defaults to the newest stash object created
drop [id]:
- delete stash object <id>
- <id> defaults to the newest stash object created
switch <short_name>
- switch to 'trunk', branch name, or tag name without having to specify
the full URL
- falls back to Subversion "switch" if <short_name> doesn't exist
tag[s]
- tag: list tags
- tag -d <name>: delete tag <name>
- tag -m <old> <new>: rename tag <old> to <new>
- tag <name> [source_ref[@rev]]: create tag <name>; if source_ref is given
it is resolved as a reference name (can be 'trunk', or another tag or a
branch name); if source is not given the HEAD of the current working-
copy URL is used
url
- output repository URL of current working directory
users
- show a list of contributing users to a SVN path
watch-lock
- block until the lock on a file/URL is released
If the subcommand name begins with two leading underscores ("__"), the
underscores will be stripped and the command will be handled by native
Subversion without any jsvn processing.
Configuration:
jsvn will execute the files "~/.jsvn", and "$WCROOT/.svn/jsvn", in that
order, if they exist, as Python scripts for the user to locally configure
jsvn. Variables written to from within configuration scripts will be used
as configuration directives to control jsvn's execution. jsvn's default
settings or even user-specified settings can thus be overridden for a
particular working copy by creating a "$WCROOT/.svn/jsvn" script.
Available configuration variables:
use_color: True or False to enable/disable colorization of svn output
use_pager: True or False to enable/disable automatic piping of svn
output to a pager program
pager: A string specifying the pager program (and args) to execute
aliases['XXX']: A string or list defining the alias 'XXX'. A string
can be used if the alias expands to a single argument. A
list must be used to pass multiple arguments to svn.
An arbitrary shell command can be specified by beginning the
alias definition with a '!' character. In this case, the shell
variable $0 will contain the subcommand specified by the user
on the command line, and $1, $2, ... will contain any positional
parameters specified on the command line.
Starting with jsvn v1.2, user configuration scripts may define
python functions to be used as aliases. The execution
environment for these user-defined functions is limited but
does provide the following symbols:
- Popen, PIPE: passed from the subprocess module for arbitrary
command execution
- do(cmd, expand=True): the do() function allows the alias
function to execute a command within jsvn. 'cmd' should be
either a string if the command has no arguments, or a list
containing the command and all arguments. 'expand' is a
boolean flag determining whether user-defined aliases should
be used to expand the command. If an alias function invokes
do() with the same command that the alias function itself is
bound to, and expand is not set to False, then the alias
function will be called recursively!
svn: Specify the path to the native Subversion executable. If not
specified, the first 'svn' in $PATH will be used.
ignore_executable_extensions: A list of extensions (including the '.')
for newly added files which should not automatically have the
svn:executable property added for them even if the files are
executable. The default value is ['.c', '.cc', '.h', '.txt'].
Configuration Examples:
pager = 'less -FRXi' # enable case-insensitive searching in less
aliases['revert'] = ['revert', '-R'] # default to recursive reverts
aliases['s'] = ['status', '--ignore-externals']
aliases['status'] = '__status' # ignore jsvn processing of status command
aliases['init'] = '!svnadmin create $1'
def up_and_ctags(args):
do(args, expand=False) # do the actual update command
Popen(['ctags', '-R']).wait()
aliases['up'] = up_and_ctags
