CCDB 1.00 release notes

Information about files and mktbl from file

It is usual situation when one already has data file and want to create table to store it. mktbl -f helps with this

> mktbl /test/haha -f python/tests/test_table.txt #my lonely comment
The command to create table: 

mktbl /test/haha -r 2 X Y Z #my lonely comment

Comments in file: 
Test assignment for software tests

Now one can copy it and run. It is not done automatically to be sure the values are reviewed.

The file is:

#Test assignment for software tests
#& X            Y            Z
  2.2          2.3          2.4         
  2.5          2.6          2.7     

You may notice that line with column names starts with #& while normal comments starts with plain #

One can use column types right there:

#& X=int            Y=int            NOT_Z=string

-f flag added to Info command also. info -f gives the info of text files, how CCDB sees it.

 ~/halld/ccdb/trunk $ ccdb info -f $CCDB_HOME/python/tests/test_table.txt
Rows: 2
Columns: 3
Column names:
    X
    Y
    Z

Comments in file: 
Test assignment for software unit tests

Type 'ccdb mktbl -f /home/romanov/halld/ccdb/trunk/python/tests/test_table.txt' to see how to create a table for the file
Type 'ccdb add <table name> /home/romanov/halld/ccdb/trunk/python/tests/test_table.txt #<comments>' to add the file to existing table (rows and columns must consist)

ls update

When ls is used directly on a table name, it gives data versions (as vers command):

 ccdb ls /test/test_vars/test_table
/test/test_vars/test_table

-l flag adds info about table like (info) command.

The flags of ls command changed too:

Lists directories and tables for current directory

- Accepts wildcards symbols '*', and '?'

keys:
    -v or --variations   - prints all variations
    -t or --tables       - prints full path for all tables
    -d or --directories  - prints all directories
    -x or --dtree        - draws directory tree

    -l or --extended     - shows extended info when is used on table
