* ck
*The Config Keeper*

* build it
** requirements
- clang (llvm) or gcc (gnu)
- cmake
- sqlite3-dev

** compiler
#+BEGIN_SRC sh
  > export CC=clang
  # or
  > export CC=gcc
#+END_SRC

** make
#+BEGIN_SRC sh
  # clone the repo
  > cd ~/code; git clone https://gitlab.com/grm-grm/ck
  # make a build directory and enter it
  > mkdir ~/ck_build; cd ~/ck_build;
  # run cmake
  > cmake ~/code/ck
  # run make
  > make
  # run ck
  > ./ck
#+END_SRC

* for devs
** CMake options
cmake accepts the following options:
#+BEGIN_SRC cmake
  option(CK_ASAN "Build with asan")
  option(CK_DEBUG "Build with debug symbols")
  option(CK_TESTS "Make the tests")
  option(CK_SHARED "Build with shared lib")
#+END_SRC

To use any one of them append it after the cmake command like so:
#+BEGIN_SRC sh
  cmake -DCK_ASAN=1 -DCK_DEBUG=1 -DCK_TESTS=1 ~/code/ck
#+END_SRC

Just build with address sanitizer enabled like so:
llvm has better asan than gcc, so I use that.
#+BEGIN_SRC sh
  # clone the repo
  > cd ~/code; git clone https://gitlab.com/grm-grm/ck
  # make a build directory and enter it
  > mkdir ~/ck_build; cd ~/ck_build;
  # run cmake
  > cmake -DCK_ASAN=1 -DCK_DEBUG=1 -DCK_TESTS=1 ~/code/ck
  # run make
  > make
  # run ck
  > ./ck
#+END_SRC

** tests
The testing "suite" is a bash script that runs regression
and unit tests. Regression tests are under the =tests/= directory
and are bash scripts that test =ck= functionality. Unit tests reside
under =unit/= directory and test the code.

*** run tests
Simply go to the build dir and type.
#+BEGIN_SRC sh
$ ./check_ck
#+END_SRC

*** test suite
#+BEGIN_SRC sh
$ ./check_ck -h
ck test suite
use without flags to run all tests

flags:
  -u, --unit            run only the unit tests
  -r, --regression      run only the regression tests
  -c, --clear           remove test files
             		 use if the tests crush unexpectedly
  -h, --help, *         print this
#+END_SRC
* manual
ck's goal is to assist with the configuration file management.
To that end it tries to provides a cli interface that is pretty straight-forward
and intuitive.

Example usage:
#+BEGIN_SRC sh
  # initialize new ck
  $ ck init /path_to/where_you_want/your_configs/to_be \
    /path_to/the_secret/directory

  # add emacs configs
  ## primary config
  $ ck add emacs ~/.emacs.d/orgconf.org -p
  ## secret config, with passwords and naughty words
  $ ck add emacs ~/.emacs.d/accounts.org -s
  ## and another one for emacs
  $ ck add emacs ~/.emacs.d/init.el

  # add tmux config
  $ ck add tmux ~/.tmux.conf -p

  # list the configs
  $ ck list tree
  $ ck list paths -t lisp
  $ ck list programs -t python

  # search the configs
  $ ck search search-term
  $ ck search "\"search term with spaces\""
  $ ck search "\(" #escape symbols
#+END_SRC

The first command after typing *ck* is the action you wish to perform. Actions are 
a very important concept of ck. With an action you can initialize *ck*, add/move/delete
configuration files to it, edit them, list them in various ways and search in their content.

Actions expect their arguments in the order specified below. This is done to reduce the amount
of flags one has to pass to ck.

** ck configuration
ck uses sqlite to index the configuration files. The init
action creates a *.ck* directory (under $HOME)
in witch the *ckrc* and the *ckdb* reside. The first one contains
the two directories described above while the other one is the
sqlite db.

One can have multiple config directories with different configurations
each.

Using the special keyword *config* (or *conf* or *c* or *-c*) you can set the path
in which ck will search for the *.ck* directory.

You can prefix every action with this and ck will use the configuration
directory of your choice.

Usage:
#+BEGIN_SRC sh
  $ ck config ~/ ... # the default behaviour

  # /someplace/else must exist or
  # the action following it must be init
  $ ck conf /someplace/else ... 

  # same thing
  $ ck c /someplace/else ... 
  $ ck -c /someplace/else ... 
#+END_SRC

** Actions
*** init 
or i or -i

init takes exactly 2 arguments.

- *config_dir*: where all the configs will live
- *secret_dir*: where all the secret configs will live

Use init to initialize a new ck database.

Usage:
#+BEGIN_SRC sh
  # initialize new ck
  $ ck init /path_to/where_you_want/your_configs/to_be \
    /path_to/the_secret/directory
#+END_SRC

*** add 
or a or -a

Adds a configuration to the ck database.
Add takes 2 to 4 arguments.

- *program_name*: the name of the program you add a config to
- *config_path*: the path to the config
- Optional: (order doesn't matter)
  + *-p*: the config will be the primary (relevant on edit below)
  + *-s*: the config will be stored in the secret_dir

Keep in mind:
- The config has to exist.
- If you are adding a config to a program already existing in ckdb make
 sure to use the same name.
- Each program can have only one primary config.

Usage:
#+BEGIN_SRC sh
  # add config to ck
  $ ck add program_name config_path [-s] [-p]
#+END_SRC

*** list
or ls or l or -l

List can show the *paths* or the *programs* that ck keeps track of.

With the flag *-t* and then one of the follwing types one can change
the way the list is printed:
- *plain*: simple listing (default)
- *python*: print like a python list
- *lisp*: print like a lisp list

Using the keyword *tree* ck can list the configurations under their
corresponding program.

Passing the *-a* flag will enable the listing of config attributes (secret or primary). 
It is best used with tree or plain paths.

Usage:
#+BEGIN_SRC sh
  # list tree structure, with attributes
  $ ck list tree -a
  # list paths in python
  $ ck l paths -t python
  # list programs in lisp
  $ ck ls programs -t lisp
#+END_SRC

*** search
or s or -s

Perform infile grep in all the configurations ck keeps track of.

Takes one argument, the *search-term*.

To search for terms with spaces you have to put them in quotes.

Usage:
#+BEGIN_SRC sh
  # search for parenthesis
  $ ck search \(
  # search term with spaces
  $ ck search "This is a space"
  # both
  $ ck search "(add 2 4)"
  # and a normal one
  $ ck search alias
#+END_SRC

If you want to use more advanced grep techniques or even
a different pattern matching program you can do it like so:

#+BEGIN_SRC sh
  # with xargs
  $ ck ls paths | xargs grep -E 'A|B'
  # or in bash
  $ for i in $(ck ls paths); do grep -E 'A|B' $i; done
  # or in zsh
  $ for i ($(ck ls paths)) grep -E 'A|B' $i
#+END_SRC

*** edit 
or e or -e

==--WIP--==

Currently edit can only edit the primary config of a program.

To do it use:
#+BEGIN_SRC sh
$ ck edit program_name
#+END_SRC
