Abstract

PURPOSE:To freely combine options in correspondence with the use environment of respective users by extracting a character string defined in a profile file from the character string appearing in the operand of an inputted command and converting it into a basic option of the combination of plural basic options. CONSTITUTION:When the command is inputted from a keyboard and a command file, a command reception part 12 receives the command and analyzes the option designated in the operand. An option conversion processing part 13 extracts the character string defined in the profile file 15 from the character string appearing in the operand of the inputted command and executes a processing converting the character string into the basic option or the combination of plural basic options from the description of composite option concerned. Thus, the description of the command operand used in correspondence with the use environment of respective users is simplified and the options can freely be combined.

Description

[Detailed Description of the Invention] [Summary] Software functions that realize multiple types of processing are
Regarding the command option specification processing method in data processing systems that can be selected by command operand options, the description of the command operands to be used has been simplified and options can be freely combined according to each user's usage environment. The purpose is to.

A profile file that stores definition information that alternatively represents a basic option of a command or a combination of multiple basic options using a character string specified by one user, and a character string that appears in the operand of the input command. Extract the defined string,
and an option conversion processing unit that converts it into a basic option or a combination of a plurality of basic options.

(Industrial Application Field) The present invention relates to a command option specification processing method for a data processing system in which functions of software that implement multiple types of processing can be selected by options of command operands.

[Conventional technology]

When using software that can perform multiple types of processing, the user often selects the functions to be used by providing specific keywords (hereinafter referred to as options).

Especially if the software is started with a command.
Specify options using command operands.

However, with this conventional method.

There are the following problems.

(i) Since keywords to be used as options are determined by the software developer, the same or R4Q functions may be specified by different options in five different software programs.

For this reason, when trying to use multiple software in a series of tasks, it is necessary to understand a variety of options.

(II) When performing fast-track work, that is, routine work that has non-routine parts, an option that specifies the function of the routine part must be specified each time. A means of implicitly giving a list of options is often provided as a function of the command processor, but this creates a large number of command sequences with different names that are reduced to the same command, which becomes uncontrollable. Sometimes.

FIG. 5 shows an example of a prior art technique for simplifying the description of such options.

In FIG. 5, "frt" is a command name, and the sequences other than blank characters starting with a hyphen (-) on the right side are options.

A detailed explanation of the options is omitted, but
The command string shown in Figure 5 (a) has a file name of 5aI.
lp1. It instructs to compile the FORTRAN source programs ``f'' to samp4.f'' under the respective options.

There are many common options depending on the user and computer installation, but as shown in Figure 5 (a),
Specifying basic options each time takes time to enter a command and increases the chances of input errors.

Therefore, conventionally 1, for example, a function called a shell variable is used, and as shown in Figure 5 (b), a string of commonly used options is stored in a shell variable (in this example,
The description of the operand is simplified by assigning it to $XX) and writing a shell variable call ($XX) as the operand of the command.

However, even with this method, calls to shell variables must be written for each operand each time, and the user must be aware of the shell variables, which is cumbersome.

[Problem to be solved by the invention]

The present invention aims to solve the above-mentioned problems and to simplify the description of command operands to be used in accordance with each user's usage environment, and to enable options to be freely combined.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention.

In FIG. 1, 10 is a command input device.

11 is a data processing device consisting of a CPU and memory, etc.; 12 is a command reception unit that accepts commands; 13 is an option conversion processing unit that converts compound options into basic options; and 14 is a command execution unit that executes command processing according to the options. 15 is a profile file used for converting options; 15-1 is a user-specific profile file prepared for each individual; 15-2 is a user-shared profile file commonly prepared for each user; and 16 is a command.

The present invention has a profile file 15 that stores definition information in which basic options of five commands or combinations of a plurality of basic options are alternatively expressed using character strings specified by the user. Profile file 1
5 includes a user-specific profile file 15-1 prepared for each individual, and a user-shared profile file 15-2 commonly used by each user.

The contents of these profile files 15 are as shown in FIG. 1 (b), and consist of descriptions of default options and descriptions of each definition option.

The default option is definition information that is implicitly valid for each command.9 For example, the option written in the first line of the profile file 15 is taken as the default option.

If the default option is not required, the first line may be left blank to instruct non-use of the default option.

The definition option is represented by a character string that is one alternative representation of the compound option written on the right side of the equal sign. A compound option is definition information consisting of a basic option or a combination of a plurality of basic options that can be interpreted by the command execution unit 14.

When a command is input from the keyboard or a command file, the command reception unit 12 accepts the command and analyzes the options specified by the two operands. Here, the option conversion processing unit 13 extracts the character string defined in the profile file 15 from the character string appearing in the ogland of the input command, and extracts the character string defined in the profile file 15 from the description of the corresponding compound option. Performs processing to convert into a combination of basic options.

In this conversion, if a default option is defined in the profile file 15, the option conversion processing unit 13 unconditionally adds that option to the operand of the command.

When the profile file 15 consists of a user-specific profile file 15-1 prepared for each individual and a user-shared profile file 15-2 commonly used by each user, the option conversion processing unit 13 converts the user-specific profile file 15-1 and the user shared profile 152 for optional conversion selectively or according to a predetermined priority order.

The above enables flexible option specification.

[Effect]

In the present invention, an option is realized as a basic option that cannot be divided into two, and a composite option that is a combination of these basic options. Composite options can be easily defined or modified by the user of the software via the profile file 15. Note that the user-specific profile file 151 and the user-shared profile file 15-2
are in the same format and can be edited with a normal editor.

For example, assume that a profile file 15 as shown in FIG. 1(C) is prepared. Here, the default option is -3w-Aa''.

-Em -Kc'' is alternatively represented by the character string °'-Ua''. Similarly, "-DN" is alternatively represented by the character string "-Ub", and -Px" is alternatively represented by the character string "-Uc".

When such a profile file 15 is prepared, the command 16 (command name=
cmd), the option conversion processing unit 13 converts the default option and the user-defined option "-Ua" from the profile file 15 into a basic option sequence "-3w" as shown in the command 16'.
-Aa-Em -Kc" and is handed over to the command execution unit 14.

〔Example〕

FIG. 2 shows an application example of the present invention, FIG. 3 shows an example of option conversion according to an embodiment of the present invention, and FIG. 4 shows a flow of option conversion processing according to an embodiment of the present invention.

For example, as shown in FIG. 2, the present invention can be applied to option analysis processing of a FORTRAN compiler.

The FORTRAN compiler main body 21 provides dozens of basic options, such as area boundary restrictions, whether to specify debugging, and whether to output minor error messages.

When the frt command reception unit 20 accepts a command string in which a basic option and a compound option are described as operands, it imports the definition of the compound option from the profile file 15 and uses the shell variable reference function 22 to change the variable name to FORT7EC. Referring to the shell variables of
Converts the options, converts all the basic options, and converts them to the FORTRAN compiler main body 21
Notifies the sequence of the two basic options.

FIG. 3 shows a concrete example of the option conversion.

The profile file 15 can be edited in advance with a suitable text editor, and in the example shown in FIG.
-Ub'' In this example,
The character string of the user-defined option is specified to be represented by a character string starting with "-U".

Assume that a command 16 shown in FIG. 3 is input when such a profile file 15 is prepared.

Here, the FORT7EC shell variable is '-Aabi
-Kcg -3w -Px' is defined.

The frt command receiving unit 20 shown in FIG.
Since EC is defined as a shell variable name that describes a common option, explicit notation of shell variables such as "$FORT7EC" can be omitted in each command.

The frt command receiving unit 20 uses the profile file 15
In response to the input of the command 16 shown in FIG. 3, the shell variable reference function 22 generates a sequence of basic options as shown in the command 16'. That is, the user can input a simplified command like command 16 manually instead of inputting a command like command 16' shown in FIG.

FIG. 4 shows an example of the processing of the option conversion processing section 13 shown in FIG. The following will explain the processes ① to ② shown in FIG. 4.

■ First, it is checked whether a user-specific profile file exists for the command operand description, which consists of basic options and compound options. If there is a user-specific profile file, move on to 2 process ■; if there is not,
Move on to processing ■.

■ Import the user-defined information from the user profile file, then move on to process ■.

■ If there is no user-specific profile file Import the user-defined information from the user coexistence profile file. In this embodiment, either the user-specific profile file or the user-shared profile file is selectively used, but both may be used. In this case, when definition information overlaps, for example, Give priority to the definition in the user-specific profile file.

■ Separate the contents of the profile file into "compound option definition" and "default option list".

■ Arrange the options in the following order.

i) Default options in the profile file.

ji) Options written in shell variable FORT7EC.

1ii) Options written in command operands.

Note that the priority for one duplicate description is that ji is large,
i is the smallest.

■ Expand the compound option placed in process ■ into basic options.

■ Through the above processing, a list of only basic options is obtained and carried over to the main processing of the command.

By using the present invention, for example, standard options can be set at the following levels.

(a) Actually specified by the operand (variable in each case).

(b) Specified using shell variables (variable for each business procedure)
.

(C) Specified in the profile file (variable for each user or installation).

(d) Specified during command development (common to all users).

〔Effect of the invention〕

As described above, according to the present invention, it is possible to simplify the description of command operands to be used and to select options for commands with flexibility, depending on each user's usage environment.

Furthermore, when business procedures are written in command files, the number of options that need to be written in the business procedures is reduced, making it easier to maintain and manage the files that describe business procedures.
