Abstract

PURPOSE:To improve the readability by making name marks the same between an input specifications description or an input source program, and an output specifications description or an output object program by sharing name mark converting information by each function of a language processing system. CONSTITUTION:A name mark converting information generating means 3-3 provided on a language processing system 1 converts an input name mark into an output name mark, and registers their corresponding relation in name mark converting information 2. The name mark converting information retrieving means 3-2 of a name mark managing means 3 retrieves the name mark converting information 2 by setting the input name mark and the output name mark as keys and obtaines the output name mark and the input name mark. In such a manner, the input name mark and output name mark can be managed integrally. Also, the output name mark of a variable name, a function name and a type name, etc., in an output specifications description or an output source program can be displayed by the input name mark described by an input specifications description or an input source program.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a name management method for a language processing system, and relates to a name management method for a language processing system, and relates to a name management method for name management in an input/output specification description or an input source program/output object program in a language processing system that processes specification descriptions or language descriptions. This paper relates to name management methods for language management systems that manage language management systems.

0002

[Prior Art] Conventional name management methods of language processing systems such as compilers or automatic generation systems use input names, which are names in input specification descriptions or input source programs, to be used in output specifications or output object programs. It is converted into an output name name that is a name name that satisfies the constraints.

[0003] The above-mentioned constraints are, for example, constraints on the execution machine, and when an input name is referenced between modules, a name subject to a character count constraint on the input name is treated as an output name. These restrictions include the inability to use name tags in Japanese.

[0004] Also, the above conversion means that, for example, when sharing a name tag with another module, up to 8 characters from the beginning of the input name specified by the user are used as the output name, and within the module. This is a conversion in which the compiler automatically generates an output name from a single input name.

[0005]

[Problem to be Solved by the Invention] The name management method of the conventional language processing system described above has the problem that when software is ported from another machine at the source program level, the effective number of characters of the name does not match the ported machine. If the name tag is different from the other machine, the uniqueness of each name tag may be lost, which poses a problem in that portability is impaired.

[0006] Furthermore, if the most severe constraint among the constraints of each machine to be ported is used as a base to improve portability, the input specification description or the name on the input source program will be constrained, resulting in a decrease in readability. There is a problem with this.

Furthermore, if Japanese output names cannot be used in the output specification description or output object program, even if Japanese names can be written in the input specification description or input source program, each module Since the connections between the two are made using non-Japanese names,
There is a restriction that the input name that can be written in Japanese must be an input name that is closed within the module, so in this case, the output name is displayed as alphanumeric characters, so one name The user has to be aware of a plurality of different names regarding the meaning of the name, which also has the problem of reducing readability.

[0008]

[Means for Solving the Problems] The name management method of the language processing system of the present invention uses names such as variable names, function names, type names, etc. in the input specification description or input source program of the language processing system. The input name is converted into an output name that is a name that satisfies the constraints of the output specification description or the output object program according to user specifications or default name conversion/generation rules, and the input name and the output name are Name name conversion information generation means that registers the correspondence of names in name name conversion information according to the sharing level of each name name; Name name conversion information search means for searching according to the sharing level and searching for a corresponding input name name from name conversion information as an output name key according to the sharing level of each name name. It is composed of means.

Embodiments Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the name management system of the language processing system of the present invention.

Referring to FIG. 1, this embodiment comprises a language processing system 1 including name name management means 3 and name name conversion information 2. Furthermore, the name name management means 3 includes a name name conversion/generation rule 3-1 and a name name conversion information retrieval means 3-1.
2, and name conversion information generating means 3-3.

The language processing system that is the object of the present invention is a software development/execution environment that includes functions such as a compiler, an automatic generation system, a language editor that references correspondence, a loader, and the like.

Name conversion/generation rule 3-1 converts the input name, which is the name specified by the user on the input specification description or the input source program, to the constraints on the output specification description or the output object program. This is a rule for converting/generating an output name that satisfies the name, and uses either a user-specified rule or a rule that the system has as a default value.

[0014] Furthermore, name conversion information 2 indicates the correspondence between input name names and output name names, and these relationships are managed hierarchically for each group according to the sharing level. . Note that the sharing level is an index indicating whether it is closed within a module, shared between modules, or shared between programs. Considering partial compilation, etc., the shared name name correspondence may be referenced/updated by multiple compilers or automatic generation systems at the same time, so the name name conversion information 2 is This is realized by a means that allows simultaneous update control.

On the other hand, the name conversion information search means 3-2 is a means for searching the name conversion information 2 for the corresponding output name or input name from the input name or output name, depending on the sharing level. It is.

Further, the name name conversion information generating means 3-3 generates an output name name from the input name name of the group, and registers the correspondence relationship in the name name conversion information 2 according to the sharing level.

Next, the operation of the main parts of the name tag management means 3 will be explained.

FIG. 2 is a flowchart showing an example of the operation when an input name mark is specified as an input in this embodiment.

As shown in FIG. 2, the output name name corresponding to the input name name is extracted from the name name conversion information 2 by name name conversion information retrieval means 3-.
2 to search according to the sharing level of the input name (3-
a1), when the relationship between the input name name and the output name name has already been defined (3-b1), that is, when the language processing system 1 to be searched or the name name conversion information 2 is shared; If the language processing system 1 has already defined the correspondence, return the searched output name (
3-d1). In addition, if the relationship between the input name name and the output name name is undefined (3-b1), that is, any language processing system 1 sharing the name name conversion information 2 will be able to use the output name corresponding to the input name name. If the name name has not been generated, the name name conversion information generating means 3-3 generates a corresponding output name name according to the name name conversion/generation rule 3-1, and determines the correspondence between the input name name and the output name name. Register the relationship in name conversion information 2 according to the sharing level (3-c1), and return the generated output name (3-c1).

FIG. 3 is a flowchart showing an example of the operation when an output name mark is specified as an input in this embodiment.

As shown in FIG. 3, the input name name corresponding to the output name name is extracted from the name name conversion information 2 by the name name conversion information retrieval means 3-.
2 to search according to the sharing level of the output name (3-
a2) If the relationship between the input name and the output name has already been defined (3-b2), the searched input name is returned (3-d2). In addition, if the relationship between the input name name and the output name name is undefined (3-b2), that is, any language processing system 1 sharing the name name conversion information 2 will be able to use the output name corresponding to the input name name. If the target has not been generated, an error is notified (3-c2).

[Effects of the Invention] As explained above, the name name management method of the language processing system of the present invention shares name name conversion information with each function of the language processing system, thereby converting input name names and output name names. It is now possible to centrally manage and display output names such as variable names, function names, and type names in output specification descriptions and output object programs with input names written in input specification descriptions or input source programs. This has the effect that the names in the input specification description or input source program and the output specification description or output object program are made the same, thereby improving readability.

A further advantage is that the input source program or input specifications can be ported without being aware of the constraints of output specification descriptions or output object programs that depend on each machine.

Furthermore, the name management method of the language processing system of the present invention does not impair the conventional format of the output specification description or the output object program itself;
Another advantage is that when executing an output specification description or an output object program, no changes are required compared to the conventional case.
