NAME


cwgen - generate groups of random characters for Morse code practice

SYNOPSIS


cwgen [-g --groups=groups] [-n --groupsize=groupsize] [-n --groupsize=group_min-group_max]
[-r --repeat=repeat] [-x --limit=limit] [-c --charset=charset] [-h --help] [-V --version]

cwgen installed on GNU/Linux systems understands both short form and long form command
line options. cwgen installed on other operating systems may understand only the short
form options.

Options may be predefined in the environment variable CWGEN_OPTIONS. If defined, these
options are used first; command line options take precedence.

DESCRIPTION


cwgen provides a simple method to generate groups of random characters for use as input
into cw. Command line options control the group size, number of groups, and character set
from which the random characters are selected.

COMMAND LINE OPTIONS
cwgen understands the following command line options. The long form options may not be
available in non-LINUX versions.

-g, --groups
Specifies the number of groups of random characters to generate. The default value
is 128.

-n, --groupsize
Specifies either the number of random characters in each group, if a single value
is given, or a range for the number of random characters in each group if a dash-
separated pair of values is given. If a range is given, cwgen generates groups
sized randomly between 'group_min' and 'group_max'. The default value is 5.

-r, --repeat
Specifies the number of times to repeat each group. The default value is 0,
indicating that each group is printed just once.

-x, --limit
Specifies an upper limit on the number of characters printed. This option is
useful when using random group sizes, to ensure a given amount of practice text.
The default value is 0, indicating no upper limit on the number of characters
printed.

-c, --charset
Defines the character set from which the random characters are selected. The
default value is 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'.

EXAMPLES


Generate 20 groups of 10 characters from the set EISH5, and sound them as Morse code.
Both short-form and long-form option examples are shown:

cwgen -g 20 -n 10 -c "EISH5" | cw -w 25 -t 850

cwgen --groups=20 --groupsize=10 --charset="EISH5" | cw --wpm=25 --tone=850
