.SH DESCRIPTION |
| 40 |
|
.I Rcode_ident |
| 41 |
< |
Takes a list of ASCII identifiers on the input and encodes them |
| 41 |
> |
takes a list of ASCII identifiers on the input and encodes them |
| 42 |
|
as a 16-bit index to a table appended to the output. |
| 43 |
|
This default index size can hold up to 65 thousand unique IDs, |
| 44 |
|
which is suitable for most applications. |
| 48 |
|
if 256 or fewer unique identifiers appear on the input. |
| 49 |
|
The |
| 50 |
|
.I \-24 |
| 51 |
< |
option creates a 24-bit index can record over 16 million |
| 51 |
> |
option creates a 24-bit index that can record over 16 million |
| 52 |
|
unique identifiers. |
| 53 |
|
.PP |
| 54 |
|
Identifiers are separated by newlines by default, but any single-character |
| 61 |
|
.PP |
| 62 |
|
Input is taken from the first named file, or standard input if no |
| 63 |
|
files are given. |
| 64 |
+ |
(Input file is required for |
| 65 |
+ |
.I \-r |
| 66 |
+ |
option.) |
| 67 |
|
Output is sent to the second named file, or standard output if none. |
| 68 |
|
.PP |
| 69 |
|
The |
| 94 |
|
The |
| 95 |
|
.I \-tS |
| 96 |
|
option specifies an alternate ID separator instead of the default newline. |
| 97 |
+ |
The |
| 98 |
+ |
.I \-l |
| 99 |
+ |
option tells |
| 100 |
+ |
.I rcode_ident |
| 101 |
+ |
to list identifiers following the header information (if present). |
| 102 |
+ |
The |
| 103 |
+ |
.I \-n |
| 104 |
+ |
option prints identifier table indexes rather than the strings themselves. |
| 105 |
+ |
Indexing starts from 0 for the first table entry. |
| 106 |
|
.PP |
| 107 |
|
When decoding, the |
| 108 |
|
.I \-i |
| 127 |
|
To query specific modifiers using ximage with the 't' command: |
| 128 |
|
.IP "" .2i |
| 129 |
|
ximage -op render.hdr | rcode_ident -i -r mods.idx |
| 130 |
+ |
.PP |
| 131 |
+ |
To only print out the list of unique identifiers: |
| 132 |
+ |
.IP "" .2i |
| 133 |
+ |
rcode_ident -r -h -H -i -l mods.idx < /dev/null |
