"154-其他资源-bison2.51" Bison是一个Yacc兼容的解析器生成器，主要用于创建计算机程序的语法解析器。这个资源是Bison的版本2.51，由Charles Donnelly和Richard Stallman编写，日期为2011年5月14日。Bison通过读取用户提供的语法规则描述文件（通常以.y或.yy扩展名），生成相应的C语言代码，该代码能够解析符合这些规则的语言输入。在软件开发中，解析器是处理输入数据并将其转换为可操作结构的关键组件。Bison使得开发者能够专注于定义语言的语法规则，而不是手动编写复杂的解析算法。它遵循一种称为LALR(1)的解析策略，这是一种上下文无关文法解析方法，适用于大多数编程语言和特定领域的语言。使用Bison时，你需要创建一个包含文法规则、语义动作和符号表定义的输入文件。这些规则描述了语言的结构，而语义动作则定义了当解析器遇到特定语法结构时应执行的操作。Bison将这个输入文件转换成一个C源代码文件，编译后可以链接到你的应用程序中。 Bison手册是用户指南，详细介绍了如何使用该工具，包括语法规范的写作技巧、错误处理、冲突解决以及如何调试生成的解析器。手册还提到了GNU Free Documentation License，这意味着你可以自由地复制、分发和修改文档，支持了自由软件基金会（FSF）的理念。此外，手册中包含了关于如何在不同操作系统上安装和配置Bison的信息，以及有关如何与其他GNU工具（如Flex，一个词法分析器生成器）结合使用的指导。购买FSF出版的印刷版手册有助于支持其继续发展GNU项目和推广软件自由。 Bison是开发语言解析器的强大工具，尤其适用于那些需要处理复杂语法结构的应用程序。通过使用Bison，开发者可以更加专注于他们的应用程序逻辑，而不是解析器的实现细节。这个资源提供了Bison 2.51版本的详细信息和使用指南，对任何需要创建自定义解析器的人来说都是宝贵的参考资料。

8 Bison 2.5

When you convey a covered work, you waive any legal power to forbid circumvention of

technological measures to the extent such circumvention is eﬀected by exercising rights

under this License with respect to the covered work, and you disclaim any intention

to limit operation or modiﬁcation of the work as a means of enforcing, against the

work’s users, your or third parties’ legal rights to forbid circumvention of technological

measures.

4. Conveying Verbatim Copies.

You may convey verbatim copies of the Program’s source code as you receive it, in any

medium, provided that you conspicuously and appropriately publish on each copy an

appropriate copyright notice; keep intact all notices stating that this License and any

non-permissive terms added in accord with section 7 apply to the code; keep intact all

notices of the absence of any warranty; and give all recipients a copy of this License

along with the Program.

You may charge any price or no price for each copy that you convey, and you may oﬀer

support or warranty protection for a fee.

5. Conveying Modiﬁed Source Versions.

You may convey a work based on the Program, or the modiﬁcations to produce it from

the Program, in the form of source code under the terms of section 4, provided that

you also meet all of these conditions:

a. The work must carry prominent notices stating that you modiﬁed it, and giving a

relevant date.

b. The work must carry prominent notices stating that it is released under this Li-

cense and any conditions added under section 7. This requirement modiﬁes the

requirement in section 4 to “keep intact all notices”.

c. You must license the entire work, as a whole, under this License to anyone who

comes into possession of a copy. This License will therefore apply, along with any

applicable section 7 additional terms, to the whole of the work, and all its parts,

regardless of how they are packaged. This License gives no permission to license

the work in any other way, but it does not invalidate such permission if you have

separately received it.

d. If the work has interactive user interfaces, each must display Appropriate Legal

Notices; however, if the Program has interactive interfaces that do not display

Appropriate Legal Notices, your work need not make them do so.

A compilation of a covered work with other separate and independent works, which

are not by their nature extensions of the covered work, and which are not combined

with it such as to form a larger program, in or on a volume of a storage or distribution

medium, is called an “aggregate” if the compilation and its resulting copyright are

not used to limit the access or legal rights of the compilation’s users beyond what the

individual works permit. Inclusion of a covered work in an aggregate does not cause

this License to apply to the other parts of the aggregate.

6. Conveying Non-Source Forms.

You may convey a covered work in object code form under the terms of sections 4 and

5, provided that you also convey the machine-readable Corresponding Source under

the terms of this License, in one of these ways:

GNU GENERAL PUBLIC LICENSE 9

a. Convey the object code in, or embodied in, a physical product (including a phys-

ical distribution medium), accompanied by the Corresponding Source ﬁxed on a

durable physical medium customarily used for software interchange.

b. Convey the object code in, or embodied in, a physical product (including a physi-

cal distribution medium), accompanied by a written oﬀer, valid for at least three

years and valid for as long as you oﬀer spare parts or customer support for that

product model, to give anyone who possesses the object code either (1) a copy of

the Corresponding Source for all the software in the product that is covered by this

License, on a durable physical medium customarily used for software interchange,

for a price no more than your reasonable cost of physically performing this con-

veying of source, or (2) access to copy the Corresponding Source from a network

server at no charge.

c. Convey individual copies of the object code with a copy of the written oﬀer to

provide the Corresponding Source. This alternative is allowed only occasionally

and noncommercially, and only if you received the object code with such an oﬀer,

in accord with subsection 6b.

d. Convey the object code by oﬀering access from a designated place (gratis or for

a charge), and oﬀer equivalent access to the Corresponding Source in the same

way through the same place at no further charge. You need not require recipients

to copy the Corresponding Source along with the object code. If the place to

copy the object code is a network server, the Corresponding Source may be on

a diﬀerent server (operated by you or a third party) that supports equivalent

copying facilities, provided you maintain clear directions next to the object code

saying where to ﬁnd the Corresponding Source. Regardless of what server hosts

the Corresponding Source, you remain obligated to ensure that it is available for

as long as needed to satisfy these requirements.

e. Convey the object code using peer-to-peer transmission, provided you inform other

peers where the object code and Corresponding Source of the work are being oﬀered

to the general public at no charge under subsection 6d.

A separable portion of the object code, whose source code is excluded from the Cor-

responding Source as a System Library, need not be included in conveying the object

code work.

A “User Product” is either (1) a “consumer product”, which means any tangible per-

sonal property which is normally used for personal, family, or household purposes, or

(2) anything designed or sold for incorporation into a dwelling. In determining whether

a product is a consumer product, doubtful cases shall be resolved in favor of coverage.

For a particular product received by a particular user, “normally used” refers to a

typical or common use of that class of product, regardless of the status of the par-

ticular user or of the way in which the particular user actually uses, or expects or is

expected to use, the product. A product is a consumer product regardless of whether

the product has substantial commercial, industrial or non-consumer uses, unless such

uses represent the only signiﬁcant mode of use of the product.

“Installation Information” for a User Product means any methods, procedures, autho-

rization keys, or other information required to install and execute modiﬁed versions of a

covered work in that User Product from a modiﬁed version of its Corresponding Source.

10 Bison 2.5

The information must suﬃce to ensure that the continued functioning of the modiﬁed

object code is in no case prevented or interfered with solely because modiﬁcation has

been made.

If you convey an object code work under this section in, or with, or speciﬁcally for

use in, a User Product, and the conveying occurs as part of a transaction in which

the right of possession and use of the User Product is transferred to the recipient in

perpetuity or for a ﬁxed term (regardless of how the transaction is characterized),

the Corresponding Source conveyed under this section must be accompanied by the

Installation Information. But this requirement does not apply if neither you nor any

third party retains the ability to install modiﬁed object code on the User Product (for

example, the work has been installed in ROM).

The requirement to provide Installation Information does not include a requirement

to continue to provide support service, warranty, or updates for a work that has been

modiﬁed or installed by the recipient, or for the User Product in which it has been

modiﬁed or installed. Access to a network may be denied when the modiﬁcation itself

materially and adversely aﬀects the operation of the network or violates the rules and

protocols for communication across the network.

Corresponding Source conveyed, and Installation Information provided, in accord with

this section must be in a format that is publicly documented (and with an implementa-

tion available to the public in source code form), and must require no special password

or key for unpacking, reading or copying.

7. Additional Terms.

“Additional permissions” are terms that supplement the terms of this License by mak-

ing exceptions from one or more of its conditions. Additional permissions that are

applicable to the entire Program shall be treated as though they were included in this

License, to the extent that they are valid under applicable law. If additional permis-

sions apply only to part of the Program, that part may be used separately under those

permissions, but the entire Program remains governed by this License without regard

to the additional permissions.

When you convey a copy of a covered work, you may at your option remove any

additional permissions from that copy, or from any part of it. (Additional permissions

may be written to require their own removal in certain cases when you modify the

work.) You may place additional permissions on material, added by you to a covered

work, for which you have or can give appropriate copyright permission.

Notwithstanding any other provision of this License, for material you add to a covered

work, you may (if authorized by the copyright holders of that material) supplement

the terms of this License with terms:

a. Disclaiming warranty or limiting liability diﬀerently from the terms of sections 15

and 16 of this License; or

b. Requiring preservation of speciﬁed reasonable legal notices or author attributions

in that material or in the Appropriate Legal Notices displayed by works containing

it; or

c. Prohibiting misrepresentation of the origin of that material, or requiring that mod-

iﬁed versions of such material be marked in reasonable ways as diﬀerent from the

original version; or

GNU GENERAL PUBLIC LICENSE 11

d. Limiting the use for publicity purposes of names of licensors or authors of the

material; or

e. Declining to grant rights under trademark law for use of some trade names, trade-

marks, or service marks; or

f. Requiring indemniﬁcation of licensors and authors of that material by anyone who

conveys the material (or modiﬁed versions of it) with contractual assumptions

of liability to the recipient, for any liability that these contractual assumptions

directly impose on those licensors and authors.

All other non-permissive additional terms are considered “further restrictions” within

the meaning of section 10. If the Program as you received it, or any part of it, con-

tains a notice stating that it is governed by this License along with a term that is a

further restriction, you may remove that term. If a license document contains a further

restriction but permits relicensing or conveying under this License, you may add to a

covered work material governed by the terms of that license document, provided that

the further restriction does not survive such relicensing or conveying.

If you add terms to a covered work in accord with this section, you must place, in the

relevant source ﬁles, a statement of the additional terms that apply to those ﬁles, or a

notice indicating where to ﬁnd the applicable terms.

Additional terms, permissive or non-permissive, may be stated in the form of a sep-

arately written license, or stated as exceptions; the above requirements apply either

way.

8. Termination.

You may not propagate or modify a covered work except as expressly provided un-

der this License. Any attempt otherwise to propagate or modify it is void, and will

automatically terminate your rights under this License (including any patent licenses

granted under the third paragraph of section 11).

However, if you cease all violation of this License, then your license from a particular

explicitly and ﬁnally terminates your license, and (b) permanently, if the copyright

holder fails to notify you of the violation by some reasonable means prior to 60 days

after the cessation.

Moreover, your license from a particular copyright holder is reinstated permanently if

the copyright holder notiﬁes you of the violation by some reasonable means, this is the

ﬁrst time you have received notice of violation of this License (for any work) from that

notice.

Termination of your rights under this section does not terminate the licenses of parties

who have received copies or rights from you under this License. If your rights have

been terminated and not permanently reinstated, you do not qualify to receive new

licenses for the same material under section 10.

9. Acceptance Not Required for Having Copies.

You are not required to accept this License in order to receive or run a copy of the

Program. Ancillary propagation of a covered work occurring solely as a consequence of

using peer-to-peer transmission to receive a copy likewise does not require acceptance.

12 Bison 2.5

However, nothing other than this License grants you permission to propagate or modify

any covered work. These actions infringe copyright if you do not accept this License.

Therefore, by modifying or propagating a covered work, you indicate your acceptance

of this License to do so.

10. Automatic Licensing of Downstream Recipients.

Each time you convey a covered work, the recipient automatically receives a license

from the original licensors, to run, modify and propagate that work, subject to this

License. You are not responsible for enforcing compliance by third parties with this

License.

An “entity transaction” is a transaction transferring control of an organization, or

substantially all assets of one, or subdividing an organization, or merging organizations.

If propagation of a covered work results from an entity transaction, each party to that

transaction who receives a copy of the work also receives whatever licenses to the work

the party’s predecessor in interest had or could give under the previous paragraph, plus

a right to possession of the Corresponding Source of the work from the predecessor in

interest, if the predecessor has it or can get it with reasonable eﬀorts.

You may not impose any further restrictions on the exercise of the rights granted or

aﬃrmed under this License. For example, you may not impose a license fee, royalty, or

other charge for exercise of rights granted under this License, and you may not initiate

litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent

claim is infringed by making, using, selling, oﬀering for sale, or importing the Program

or any portion of it.

11. Patents.

A “contributor” is a copyright holder who authorizes use under this License of the

Program or a work on which the Program is based. The work thus licensed is called

the contributor’s “contributor version”.

A contributor’s “essential patent claims” are all patent claims owned or controlled by

the contributor, whether already acquired or hereafter acquired, that would be infringed

by some manner, permitted by this License, of making, using, or selling its contributor

version, but do not include claims that would be infringed only as a consequence of

further modiﬁcation of the contributor version. For purposes of this deﬁnition, “con-

trol” includes the right to grant patent sublicenses in a manner consistent with the

requirements of this License.

Each contributor grants you a non-exclusive, worldwide, royalty-free patent license

under the contributor’s essential patent claims, to make, use, sell, oﬀer for sale, import

and otherwise run, modify and propagate the contents of its contributor version.

In the following three paragraphs, a “patent license” is any express agreement or com-

mitment, however denominated, not to enforce a patent (such as an express permission

to practice a patent or covenant not to sue for patent infringement). To “grant” such

a patent license to a party means to make such an agreement or commitment not to

enforce a patent against the party.

If you convey a covered work, knowingly relying on a patent license, and the Corre-

sponding Source of the work is not available for anyone to copy, free of charge and under

the terms of this License, through a publicly available network server or other readily

accessible means, then you must either (1) cause the Corresponding Source to be so
