C Language Lexical analyzer written in JavaThis is the Java written C language Lexical analyzer, I also refer to a lot of code, and then the core code to organize, in the QQ Space and blog, the purpose is to learn from each other, hoping to get expert improvement. This lexical analyzer implements features that open files, save files, open Help documents, cut and

Simple logical Expression Lexical analyzer The logical expressions to be parsed are as follows: EXISTS (x) (missile (x) and owns (Father (Nono), part_of (x))) => sells (West,x,nono) To handle logical expressions, you must first extract parts of the logical expression: keywords (and, or, not, ForAll, EXISTS, =>), predicates, and arguments, and must be removed for extra spaces in an expression. This work is done by a lexical

After reading the detailed explanations of various parts of the PE file in the Software Encryption technology book, I also had the idea of writing the PE file analyzer myself. Although a good analyzer is not a minority, some friends may not understand what it means for a heap of hexadecimal numbers. If you can convert the 01 series in the program to read and understand the information directly, you can at l

PrefaceIn daily development work, we always need to write some syntax analyzers from time to time. The syntax analyzer does not necessarily refer to the front-end of a language compiler, but may also be a read/write program for configuration files designed by itself, or a DSL (domain-specific language) that simplifies our development ). We can choose to use XML, but because XML is too noisy, it is necessary to write a syntax

. Okay. What is shift? When idlist0 jumps to idlist2, it must be moved to idlist. Idlist3 jumps to idlist1 and needs to be moved to ID. Idlist0 jump to idlist1 also needs to be moved to ID. That is to say,When the state transfer passes through a non-terminator edge, it will be moved to another grammar state machine.. Id1 and idlist1 are the final nodes of ID and idlist. They must follow the "removed from there" Rules and then jump to "idlist2 or idlist1 ". That is to say,Once you reach the final

It has been a long time since the previous version. When V1.0 is used, it is called CYQ. IISLogViewer. During V2.0, a Chinese name is given, which is: Website log analyzer V2.0 After upgrading to 3.0, I changed the name:Autumn-style website log analyzer V3.0 Key points of this version upgrade:1: Overall upgrade to avoid the problem of automatic exit of software caused by thread conflicts. 2: analyze the f

To query the reason why analyzer cannot be debugged in one step, take the following steps: 1. set the server authentication attribute to hybrid mode (window and SQL authentication) 2. on the control panel, open service and open properties for the MSSQLSERVER service. on the logon page, set the logon identity to the local account and password of the server, such as administrator and password 123;3. restart the sqlserver service. at this time, the s

[Original] Microsoft baseline security analyzer tool Introduction As we all know, when conducting security testing, you can start with deployment and infrastructure, input verification, identity verification, authorization, configuration management, sensitive data, session management, encryption, parameter operations, exception management, review, and logging.. Today I would like to recommend a free security leak scanning tool Microsoft Baseline

see how a regular expression (a | B) * baa constructs a corresponding NFA. The following describes each step in detail. Figure 8 Regular Expression (a | B) * baa construction NFA example The final NFA is shown in. A total of 14 States are required. In NFA, each part of the regular expression can be distinguished. The NFA constructed here is not the simplest, so it is different from the NFA in the previous section "C # lexical analyzer (3) Regular Ex

code. Note that we have set the lexical analyzer to ignore all whitespace characters, line breaks, and comments, which are considered for easy parsing. Readers can try to expand the lexical analyzer on their own, such as adding lexical constants, more keywords and operators, and even more new lexical characters than ever before. I wish you a happy practice! At the beginning of the next chapter, we want to

So briefly write how to install memory Analyzer from scratchMemory Analyzer (Eclipse MAT) is a cross-platform, open-source tool that can be used not only to analyze the problems of the RAM, but also to monitor the state and behavior of the entire Java application. By reading the snapshot of a dump file generated by the Java runti

When I finished the lexical analyzer last week, I had a problem with a trivial but X-ache. After all, it is the first time to completely write the entire language of the compiler (so call it, the interpreter more reliable), due to lack of experience, in the string parsing this piece stopped two genius solved, here recorded for later reference. Oh yes, the reason why I want to own handwriting parser, not I do not know that there are automatic tools can

Preface In using memory analyzer tool (MAT) to analyze memory leaks (I), I introduced the causes and consequences of memory leaks. This article describes how mat analyzes the root cause of Leakage Based on heap dump. Because the test examples may be too simple and it is easy to find out the problem, I look forward to taking this as an example.At first I had to talk about classloader. In essence, its job is to read the class files on the disk into the
