./perfect_hash.py -h
Usage: ./perfect_hash.py [options] KEYS_FILE [TMPL_FILE] Generates code for perfect hash functions from a file with keywords and a code template. If no template file is provided, a small built-in Python template is processed and the output code is written to stdout. Options: --version show program's version number and exit -h, --help show this help message and exit --delimiter=STR Delimiter for list items used in output, the default delimiter is ', ' --indent=INT Make INT spaces at the beginning of a new line when generated list is wrapped. Default is 4 --width=INT Maximal width of generated list when wrapped. Default width is 76 --comment=STR STR is the character, or sequence of characters, which marks the beginning of a comment (which runs till the end of the line), in the input KEYS_FILE. Default is '#' --splitby=STR STR is the character by which the columns in the input KEYS_FILE are split. Default is ',' --keycol=INT Specifies the column INT in the input KEYS_FILE which contains the keys. Default is 1, i.e. the first column. --trials=INT Specifies the number of trials before NG is increased. A small INT will give compute faster, but the array G will be large. A large INT will take longer to compute but G will be smaller. Default is 5 --hft=INT Hash function type INT. Possible values are 1 (StrSaltHash) and 2 (IntSaltHash). The default is 1 -e, --execute Execute the generated code within the Python interpreter. -o FILE, --output=FILE Specify output FILE explicitly. `-o std' means standard output. `-o no' means no output. By default, the file name is obtained from the name of the template file by substituting `tmpl' to `code'. -v, --verbose verbosity
