DESCRIPTION¶
mytool is a
my map file manipulation program in the yudit
distribution. It can generates so-called binary nbit (
my ) map file
that can map any sequences of bytes into any sequences of bytes. These
sequences of bytes can be grouped into 1,2,4 and 8 bytes long words. The input
sequence length may be different from the matched sequence length. 'i / 'n
-> 'b specifies that the word 'in' produces 'b' but only the 'i is consumed
from the input buffer.
It can also generate a so-called
binary umap file, that maps 8 or 16 bit
single words into 16 bit single words and it contains the reverse map too.
It can also disassemble the input map and produce a
mys source file.
The input can be a binary umap file, a
my file,
mys file a
uni and a kmap file for yudit. It is recommended that all kmap files
use the new
mys format because it gives more freedom to define the
mapping.
The yudit distribution has a simple document
yudit/doc/my.doc on the
binary map formats, and a source file example file
yudit/mytool/my/example.mys please refer to this for more details.
OPTIONS¶
- -info
- prints out a small information on the current map.
- -test
- lets you test the map interactively.
- -showkeys
- show alls the keys in the map file.
- -encode
- builds a state machine in the encoding part of the map
file. The resulting map file can be written to disk with the -write
option The resulting my files can contain state machines to
speed-up conversion. A state machine based my file can manifest
10%-70% performance improvement, so it may be desirable for encoding
fontmaps. For fontmaps the bumap format might be
better suited where only one character and not a sequence of characters
need to be mapped.
- -decode
- builds a state machine in the decoding part of the map
file.
- -strip
- strips off the state machines from the map files. The
-write option can be used to save the new map file.
- -benchmark
- option performs a simple benchmark test on the map file, to
compare speed of simple, state machine based and binary map based map
files.
- -nocomment
- option strips all comments from an input source file of
format mys kmap uni. It does not strip comments from a binary
file.
- -name new-name
- assigns a name to the map file.
- -comment new-comment
- assigns a comment to the map file.
- -type new-type
- assigns a map file a distinctive type, that can be
kmap or fontmap but it is only informative. Keymaps can be
used as fontmaps and vice versa.
- -write output-file
- writes the data into an output file. mytool never
modifies the original file. All modifications should be explicitly saved
with the this option. Never specify the same file for input and
output.
- -my input-file
- load a binary map file. Only one of this option can be
specified.
- -mys input-source-file
- load a source file.
- -rmys input-source-file
- load a source file and reverse it - make encoding from
decoding and vice versa.
- -kmap input-source-file
- load a source file in kmap format.
- -rkmap input-source-file
- load a source file and reverse it - make encoding from
decoding and vice versa.
- -uni:l,u input-source-file
- load a source file in Unicode Consortium format. This
format has the local code in column l, and unicode in column u. The
numbering of columns start from 0.
- -runi:l,u input-source-file
- load a source file in Unicode Consortium format and
reverses it. Make encoding from decoding and vice versa.
- -8
- option can be used with the -uni or -runi
options. It specifies that the input is 8 bit and not 16 bit.
- -high
- option can be used with the -uni or -runi
options. It specifies that the key should be or'ed with 0x8080.
- -low
- option can be used with the -uni or -runi
options. It specifies that the key should be and'ed with 0x7f7f.
- -convert output-file-format
- converts the map file to a format. It is useful only when
combined with -write otion. The possible formats are my
-binary, mys -source, myc -my-c-source,
umap -umap-c-source, bumap -binary-umap formats.
For maps where only a single 8 or 16 bit local code should be converted
into 16 bit unicode and vice versa, the umap file formats are recommended.
The c-source files are provided so that you can inlucde a full map into
the c program.
DIAGNOSTICS¶
mytool prints out an error message and exits with a non-zero status on
error. If there is no error the exit status is zero.
