NAME
Uil — Invokes the UIL compiler from within an application "Uil" "uil functions" "Uil" "uil
compiler"
SYNOPSIS
#include <uil/UilDef.h>
Uil_status_type Uil(
Uil_command_type *command_desc,
Uil_compile_desc_type **compile_desc,
Uil_continue_type (*message_cb) (),
char *message_data,
Uil_continue_type (*status_cb) (),
char *status_data);
DESCRIPTION
The Uil function provides a callable entry point for the UIL compiler. The Uil callable
interface can be used to process a UIL source file and to generate UID files, as well as
return a detailed description of the UIL source module in the form of a symbol table
(parse tree).
command_desc
Specifies the uil command line.
compile_desc
Returns the results of the compilation.
message_cb
Specifies a callback function that is called when the compiler encounters errors
in the UIL source.
message_data
Specifies user data that is passed to the message callback function
(message_cb). Note that this argument is not interpreted by UIL, and is used
exclusively by the calling application.
status_cb Specifies a callback function that is called to allow X applications to service
X events such as updating the screen. This function is called at various check
points, which have been hard coded into the UIL compiler. The
status_update_delay argument in command_desc specifies the number of check
points to be passed before the status_cb function is invoked.
status_data
Specifies user data that is passed to the status callback function (status_cb).
Note that this argument is not interpreted by the UIL compiler and is used
exclusively by the calling application.
Following are the data structures Uil_command_type and Uil_compile_desc_type:
typedef struct Uil_command_type {
char *source_file;
/* single source to compile */
char *resource_file; /* name of output file */
char *listing_file; /* name of listing file */
unsigned int *include_dir_count;
/* number of dirs. in include_dir */
char *((*include_dir) []);
/* dir. to search for include files */
unsigned listing_file_flag: 1;
/* produce a listing */
unsigned resource_file_flag: 1;
/* generate UID output */
unsigned machine_code_flag: 1;
/* generate machine code */
unsigned report_info_msg_flag: 1;
/* report info messages */
unsigned report_warn_msg_flag: 1;
/* report warnings */
unsigned parse_tree_flag: 1;
/* generate parse tree */
unsigned int status_update_delay;
/* number of times a status point is */
/* passed before calling status_cb */
/* function 0 means called every time */
char *database;
/* name of database file */
unsigned database_flag: 1;
/* read a new database file */
unsigned use_setlocale_flag: 1;
/* enable calls to setlocale */
};
typedef struct Uil_compile_desc_type {
unsigned int compiler_version;
/* version number of compiler */
unsigned int data_version;
/* version number of structures */
char *parse_tree_root; /* parse tree output */
unsigned int message_count [Uil_k_max_status+1];
/* array of severity counts */
};
Following is a description of the message callback function specified by message_cb:
Uil_continue_type (*message_cb) (message_data, message_number, severity, msg_buffer,
src_buffer, ptr_buffer, loc_buffer, message_count)
char *message_data;
int message_number;
int severity;
char *msg_buffer, *src_buffer;
char *ptr_buffer, *loc_buffer;
int message_count[];
This function specifies a callback function that UIL invokes instead of printing an error
message when the compiler encounters an error in the UIL source. The callback should
return one of the following values:
Uil_k_terminate
Terminate processing of the source file
Uil_k_continue
Continue processing the source file
The arguments are
message_data
Data supplied by the application as the message_data argument to the Uil
function. UIL does not interpret this data in any way; it just passes it to the
callback.
message_number
An index into a table of error messages and severities for internal use by UIL.
severity An integer that indicates the severity of the error. The possible values are
the status constants returned by the Uil function. See Return Value for more
information.
msg_buffer
A string that describes the error.
src_buffer
A string consisting of the source line where the error occurred. This string is
not always available. In this case, the argument is NULL.
ptr_buffer
A string consisting of whitespace and a printing character in the character
position corresponding to the column of the source line where the error
occurred. This string may be printed beneath the source line to provide a
visual indication of the column where the error occurred. This string is not
always available. In this case, the argument is NULL.
loc_buffer
A string identifying the line number and file of the source line where the error
occurred. This is not always available; the argument is then NULL.
message_count
An array of integers containing the number of diagnostic messages issued thus
far for each severity level. To find the number of messages issued for the
current severity level, use the severity argument as the index into this array.
Following is a description of the status callback function specified by status_cb:
Uil_continue_type (*status_cb) (status_data, percent_complete,
lines_processed, current_file, message_count)
char *status_data;
int percent_complete;
int lines_processed;
char *current_file;
int message_count[];
This function specifies a callback function that is invoked to allow X applications to
service X events such as updating the screen. The callback should return one of the
following values:
Uil_k_terminate
Terminate processing of the source file
Uil_k_continue
Continue processing the source file
The arguments are
status_data
Data supplied by the application as the status_data argument to the Uil
function. UIL does not interpret this data in any way; it just passes it to the
callback.
percent_complete
An integer indicating what percentage of the current source file has been
processed so far.
lines_processed
An integer indicating how many lines of the current source file have been read
so far.
current_file
A string containing the pathname of the current source file.
message_count
An array of integers containing the number of diagnostic messages issued thus
far for each severity level. To find the number of messages issued for a given
severity level, use the severity level as the index into this array. The
possible severity levels are the status constants returned by the Uil function.
See Return Value for more information.
RETURN
This function returns one of the following status return constants:
Uil_k_success_status
The operation succeeded.
Uil_k_info_status
The operation succeeded. An informational message is returned.
Uil_k_warning_status
The operation succeeded. A warning message is returned.
Uil_k_error_status
The operation failed due to an error.
Uil_k_severe_status
The operation failed due to an error.
