DESCRIPTION
The tt_type_comp utility processes otypes and ptypes. The default
action of tt_type_comp is to compile types from source form into com‐
piled form and then merge the compiled types into the standard ToolTalk
types databases. The tt_type_comp utility preprocesses the source
types with cpp(1), and can optionally write out the compiled types
instead of merging them into the standard databases. The tt_type_comp
utility can also remove types from the standard databases or write out
the contents of these databases.
The tt_type_comp utility operates in two fundamental modes: XDR and
Classing Engine. XDR mode is the default. In XDR mode, the standard
databases are simply serialized ToolTalk data structures, and the for‐
mat of tt_type_comp output files is the same as that of the databases.
In Classing Engine mode, the standard databases are in fact the Class‐
ing Engine's own databases, and the format of tt_type_comp output files
is that expected for input to ce_db_build(1) and ce_db_merge(1).
OPTIONS
The following options are available:
−d db Specify the database to work on, which must be one of user,
system or network. For Classing Engine mode these are defined
as:
user $HOME/.cetables/cetables
system /etc/cetables/cetables
network $OPENWINHOME/lib/cetables/cetables
For the XDR format these are defined respectively as the
first, second, and last elements of $TTPATH.
These databases form a hierarchy in which the definition of a
type in the user database overrides the definition in the sys‐
tem database, and so on. For the merge and remove options,
the default database is user. For the −p, −O and −P options,
the default is all three databases.
−E Use Classing Engine mode, instead of the default XDR mode.
−G Perform garbage collection on the ToolTalk database. See
ttdbserverd(1M).
−h Write a help message for invoking tt_type_comp and then exit.
−m Merge types into the specified database, updating any existing
type with the new definition given. This is the default
action. This action is not supported for Classing Engine
mode.
−M Merge types into the specified database (see −m), but only if
they do not already exist in that database. This action is
not supported for Classing Engine mode.
−O Write the names of all otypes read.
−p Write the ToolTalk types read in a source format suitable for
recompilation with tt_type_comp.
−P Write the names of all ptypes read.
−o compiled_file
Write the compiled types into the specified file, or to stan‐
dard output if compiled_file is −.
−r Remove the given ptypes or otypes from the specified database,
as indicated by the type operands.
−s Silent mode. Write nothing to standard output.
−v Write the version number of tt_type_comp and then exit.
−x Compile source types into a compiled types file, instead of
merging them into the standard types databases.
These options will be passed through tt_type_comp to cpp: −undf −Dname
−Idirectory −Uname −Ydirectory.
OPERANDS
The following operands are supported:
source_file
A pathname of a text file containing ToolTalk source code. If
source_file is −, standard input is used.
type A name of a type to be removed by the −r option.
STDIN
The standard input is used only if a source_file operand is −.
INPUT FILES
The input file named by source_file is a text file containing ToolTalk
source code.
ENVIRONMENT VARIABLES
The following environment variables affect the execution of
tt_type_comp:
CEPATH In Classing Engine mode, a colon-separated list of
directories that tells the Classing Engine where to
find the databases that contain (among other things)
ToolTalk types. See ce_db_build(1).
LANG Provide a default value for the internationalization
variables that are unset or null. If LANG is unset
or null, the corresponding value from the implementa‐
tion-specific default locale will be used. If any of
the internationalization variables contains an
invalid setting, the utility behaves as if none of
the variables had been defined.
LC_ALL If set to a non-empty string value, override the val‐
ues of all the other internationalization variables.
LC_MESSAGES Determine the locale that is used to affect the for‐
mat and contents of diagnostic messages written to
standard error and informative messages written to
standard output.
NLSPATH Determine the location of message catalogues for the
processing of LC_MESSAGES.
TTPATH In XDR mode, a colon-separated list of directories
that tells the ToolTalk service where to find the
ToolTalk types databases. If TTPATH has no value or
is not set, it is considered to be:
$HOME/.tt:\
/etc/tt:\
/usr/dt/appconfig/tttypes:\
$OPENWINHOME/etc/tt
RESOURCES
None.
ASYNCHRONOUS EVENTS
The tt_type_comp utility takes the standard action for all signals.
STDOUT
When the −h option is used, tt_type_comp writes to standard output a
help message in an unspecified format.
When the −o option is used, tt_type_comp writes to standard output a
listing of all otypes read.
When the −p option is used, tt_type_comp writes to standard output a
listing of all the ToolTalk types read, in a source format suitable for
recompilation with tt_type_comp.
When the −P option is used, tt_type_comp writes to standard output a
listing of all ptypes read.
When the −v option is used, tt_type_comp writes to standard output a
version number in an unspecified format.
STDERR
Used only for diagnostic messages.
OUTPUT FILES
When the −x or −d user option is used, tt_type_comp writes the compiled
types in an unspecified format into a user-specified file. Otherwise,
it writes the compiled types into the databases described under −d.
EXTENDED DESCRIPTION
None.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
1 Usage; tt_type_comp was given invalid command line options.
2 A syntax error was found in the source types given to
tt_type_comp.
3 System error; tt_type_comp was interrupted by SIGINT, or encoun‐
tered some system or internal error.
CONSEQUENCES OF ERRORS
Default.
FILES
$HOME/.tt/types.xdr
User's ToolTalk types database for XDR mode
$HOME/.tt/.tt_lock
Lock file for serializing updates to user's ToolTalk types
database for XDR mode. If this file exists, will refuse to
rewrite the database. If a previous execution of exited
abnormally, a copy of this file may be left around; future
executions of will exit after printing the message
".tt_lock: File exists" several times. To clear this condi‐
tion, make sure there are no other processes running, and
remove the file.
/etc/tt/types.xdr
