# skool2ctl.py

## SYNOPSIS

`skool2ctl.py` [options] FILE

## DESCRIPTION

`skool2ctl.py` converts a skool file into a control file. The control file is written to stdout. When FILE is ‘-’, `skool2ctl.py` reads from standard input.

## OPTIONS

`-b, --preserve-base`

  Preserve the base of decimal and hexadecimal values in instruction operands and DEFB, DEFM, DEFS and DEFW statements. (By default, only binary values and character values are preserved.)

-E, –end ADDR

  Stop converting at this address. ADDR must be a decimal number, or a hexadecimal number prefixed by ‘0x’.

`-h, --hex`

  Write addresses in upper case hexadecimal format.

-I, –ini param=value

  Set the value of a configuration parameter (see `CONFIGURATION`), overriding any value found in `skoolkit.ini`. This option may be used multiple times.

`-k, --keep-lines`

  Preserve line breaks in comments.

`-l, --hex-lower`

  Write addresses in lower case hexadecimal format.

`--show-config`

  Show configuration parameter values.

-S, –start ADDR

  Start converting at this address. ADDR must be a decimal number, or a hexadecimal number prefixed by ‘0x’.

`-V, --version`

  Show the SkoolKit version number and exit.

-w, –write X

  Write only these elements, where X is one or more of:

  `a` = ASM directives
  `b` = block types and addresses
  `t` = block titles
  `d` = block descriptions
  `r` = registers
  `m` = mid-block comments and block start/end comments
  `s` = sub-block types and addresses
  `c` = instruction-level comments

  The default is to write all of these elements.

## CONFIGURATION

`skool2ctl.py` will read configuration from a file named `skoolkit.ini` in the current working directory or in `~/.skoolkit`, if present. The recognised configuration parameters are:

> Hex:

>   Write addresses in decimal (`0`, the default), lower case hexadecimal (`1`), or upper case hexadecimal (`2`).

> KeepLines:

>   Preserve line breaks in comments (`1`), or don’t (`0`, the default).

> PreserveBase:

>   Preserve the base of decimal and hexadecimal values in instruction operands and DEFB/DEFM/DEFS/DEFW statements (`1`), or don’t (`0`, the default).

Configuration parameters must appear in a `[skool2ctl]` section. For example, to make `skool2ctl.py` write upper case hexadecimal addresses by default (without having to use the `-h` option on the command line), add the following section to `skoolkit.ini`:

    [skool2ctl]
    Hex=2

Configuration parameters may also be set on the command line by using the `--ini` option. Parameter values set this way will override any found in `skoolkit.ini`.

## EXAMPLES

1. Convert `game.skool` into a control file named `game.ctl`:

   `skool2ctl.py game.skool > game.ctl`

2. Convert `game.skool` into a control file containing only block types, addresses and titles:

   `skool2ctl.py -w bt game.skool > game.ctl`
