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.
