| 26 | # DESCRIPTION |
---|
| 27 | # =========== |
---|
| 28 | # |
---|
| 29 | # Split a namelist file (NEMO convention syntax) given in parameter |
---|
| 30 | # into files in a given output directory. |
---|
| 31 | # |
---|
| 32 | # .. option:: -i <input file (namelist)> |
---|
| 33 | # .. option:: -o <output directory> |
---|
| 34 | # .. option:: -n <numbered output files> |
---|
| 35 | # |
---|
| 36 | # Each file of the output directory is named after the *block* it contains. |
---|
| 37 | # |
---|
| 38 | # We assume here that the input file is written with this pattern of block: |
---|
| 39 | # |
---|
| 40 | # .. parsed-literal:: |
---|
| 41 | # |
---|
| 42 | # !--------------- |
---|
| 43 | # &nameblock |
---|
| 44 | # !--------------- |
---|
| 45 | # var1 = val1 |
---|
| 46 | # ... |
---|
| 47 | # varn = valn |
---|
| 48 | # / |
---|
| 49 | # |
---|
| 50 | # If ``-n`` option is used, files in the directory output are named after |
---|
| 51 | # the number of the block it contains and the name of this block. This might |
---|
| 52 | # be useful to recombine blocks in the same order. |
---|
| 53 | # |
---|
| 54 | # EXAMPLES |
---|
| 55 | # ======== |
---|
| 56 | # |
---|
| 57 | # To split the namelist NEMO ORCA2_LIM experiment 00 if you are in NEMO |
---|
| 58 | # working space : |
---|
| 59 | # |
---|
| 60 | # .. code-block:: bash |
---|
| 61 | # |
---|
| 62 | # namelist_split.sh -i CONFIG/ORCA2_LIM/EXP00/namelist -o /tmp/EXP00_namelist_split/ |
---|
| 63 | # |
---|
| 64 | # To split the namelist under data directory with numbered files: |
---|
| 65 | # |
---|
| 66 | # .. code-block:: bash |
---|
| 67 | # |
---|
| 68 | # namelist_split.sh -i ./data/namelist -o /tmp/EXP00_namelist_split/ -n |
---|
| 69 | # |
---|
| 70 | # Check can be made by concatenation of files in output directory if ``-n`` |
---|
| 71 | # option have been used and comparison with original file : |
---|
| 72 | # |
---|
| 73 | # .. code-block:: bash |
---|
| 74 | # |
---|
| 75 | # cat /tmp/EXP00_namelist_split/b???_* > /tmp/EXP00_namelist_rebuild |
---|
| 76 | # sdiff -w80 ./data/namelist /tmp/EXP00_namelist_rebuild |
---|
| 77 | # |
---|
| 78 | # Output contains lines which are before the first block, after the last |
---|
| 79 | # block and lines between blocks. |
