"""Merge content of several hex files into one file."""
|
|
||||||
|
|
||||||
VERSION = '2.2'
|
|
||||||
|
|
||||||
USAGE = '''hexmerge: merge content of hex files.
|
|
||||||
Usage:
|
|
||||||
python hexmerge.py [options] FILES...
|
|
||||||
|
|
||||||
Options:
|
|
||||||
-h, --help this help message.
|
|
||||||
-v, --version version info.
|
|
||||||
-o, --output=FILENAME output file name (emit output to stdout
|
|
||||||
if option is not specified)
|
|
||||||
-r, --range=START:END specify address range for output
|
|
||||||
(ascii hex value). Both values are inclusive.
|
|
||||||
Range can be in form 'START:' or ':END'.
|
|
||||||
--no-start-addr Don't write start addr to output file.
|
|
||||||
--overlap=METHOD What to do when data in files overlapped.
|
|
||||||
Supported variants:
|
|
||||||
* error -- stop and show error message (default)
|
|
||||||
* ignore -- keep data from first file that
|
|
||||||
contains data at overlapped address
|
|
||||||
* replace -- use data from last file that
|
|
||||||
contains data at overlapped address
|
|
||||||
|
|
||||||
Arguments:
|
|
||||||
FILES list of hex files for merging
|
|
||||||
(use '-' to read content from stdin)
|
|
||||||
|
|
||||||
You can specify address range for each file in the form:
|
|
||||||
|
|
||||||
filename:START:END
|
|
||||||
|
|
||||||
See description of range option above.
|
|
||||||
|
|
||||||
You can omit START or END, so supported variants are:
|
|
||||||
|
|
||||||
filename:START: read filename and use data starting from START addr
|
|
||||||
filename::END read filename and use data till END addr
|
|
||||||
|
|
||||||
Use entire file content:
|
|
||||||
|
|
||||||
filename
|
|
||||||
or
|
|
||||||
filename::
