character as an identifier, such as hitting a number, it is possible to follow the scanned number and then look back at a small number and then scan the number until there is no number.The scan will return a scanned token, a compressed representation of the location, and a string of literals, so that a source file can be converted into a token stream of tokens, that is, the process of tokenize or lexical analysis. Func (S *scanner) Scan () (POS token

The lexical parser or scanner is mainly used to parse the text of a string, and then analyze the words in the text to recognize the attributes of a certain type. The first step in writing a compiler or parser is to do something like this: lexical analysis. There have been many ways to use string search, where regular expressions are used to accomplish this purpose.Example:Print ("Lexical analyzer") import collectionsimport Retoken = collections.namedtuple (' Token ', [' Typ ', ' value ', ' line

the string parameter matches the specified mode, true is returned; otherwise, false is returned.Example: matches ("Merano", "ran ")Result: True. FN: Replace (string, pattern, replace) Replace the specified mode with the replace parameter and return the result.Example: Replace ("bella Italia", "L ","*")Result: 'Be ** A ita *'Example: Replace ("bella Italia", "L ","")Result: 'bea itaa' FN: tokenize (string, pattern) Example:

JQuery selector code (4) -- Expr. preFilter Expr. preFilter is a preprocessing method for ATTR, CHILD, and PSEUDO selectors in the tokenize method. The details are as follows: Expr. preFilter: {ATTR: function (match) {/** to complete the following tasks: * 1. attribute name decoding * 2. Attribute Value decoding * 3. If the judgment character is ~ =, A space is added on both sides of the property value * 4. The final mtach object ** match [1] is ret

SQLite virtual machine. SQLite supports databases up to 2 TB in size, and each database is fully stored in a single disk file. These disk files can be moved between computers in different bytes. The data is stored on the disk in the form of B + tree (B + tree) data structure. SQLite obtains database permissions based on the file system.1. Public interface)Most of the public interfaces of the SQLite library are composed of main. c, legacy. C and vdbeapi. functions in the C source file are implem
