"This document is an introductory tutorial to using regular expressions in"
" Python with the :mod:`re` module. It provides a gentler introduction "
"than the corresponding section in the Library Reference."
msgstr ""

msgid "Introduction"
msgstr ""
#: ../Doc/howto/regex.rst:26
msgid ""
"Regular expressions (called REs, or regexes, or regex patterns) are "
"essentially a tiny, highly specialized programming language embedded "
"inside Python and made available through the :mod:`re` module. Using this"
" little language, you specify the rules for the set of possible strings "
"that you want to match; this set might contain English sentences, or "
"e-mail addresses, or TeX commands, or anything you like. You can then "
"ask questions such as \"Does this string match the pattern?\", or \"Is "
"there a match for the pattern anywhere in this string?\". You can also "
"use REs to modify a string or to split it apart in various ways."
msgstr ""
#: ../Doc/howto/regex.rst:35
msgid ""
"Regular expression patterns are compiled into a series of bytecodes which"
" are then executed by a matching engine written in C. For advanced use, "
"it may be necessary to pay careful attention to how the engine will "
"execute a given RE, and write the RE in a certain way in order to produce"
" bytecode that runs faster. Optimization isn't covered in this document, "
"because it requires that you have a good understanding of the matching "
"engine's internals."
msgstr ""
#: ../Doc/howto/regex.rst:42
msgid ""
"The regular expression language is relatively small and restricted, so "
"not all possible string processing tasks can be done using regular "
"expressions. There are also tasks that *can* be done with regular "
"expressions, but the expressions turn out to be very complicated. In "
"these cases, you may be better off writing Python code to do the "
"processing; while Python code will be slower than an elaborate regular "
"expression, it will also probably be more understandable."

"We'll start by learning about the simplest possible regular expressions."
" Since regular expressions are used to operate on strings, we'll begin "
"with the most common task: matching characters."
msgstr ""

"For a detailed explanation of the computer science underlying regular "
"expressions (deterministic and non-deterministic finite automata), you "

msgid "Matching Characters"
msgstr ""
#: ../Doc/howto/regex.rst:65
msgid ""
"Most letters and characters will simply match themselves. For example, "
"the regular expression ``test`` will match the string ``test`` exactly. "
"(You can enable a case-insensitive mode that would let this RE match "
"``Test`` or ``TEST`` as well; more about this later.)"
msgstr ""
#: ../Doc/howto/regex.rst:70
msgid ""
"There are exceptions to this rule; some characters are special "
":dfn:`metacharacters`, and don't match themselves. Instead, they signal "
"that some out-of-the-ordinary thing should be matched, or they affect "
"other portions of the RE by repeating them or changing their meaning. "
"Much of this document is devoted to discussing various metacharacters and"
" what they do."
msgstr ""
#: ../Doc/howto/regex.rst:76
msgid ""
"Here's a complete list of the metacharacters; their meanings will be "
"discussed in the rest of this HOWTO."
msgstr ""
#: ../Doc/howto/regex.rst:83
msgid ""
"The first metacharacters we'll look at are ``[`` and ``]``. They're used "
"for specifying a character class, which is a set of characters that you "
"wish to match. Characters can be listed individually, or a range of "
"characters can be indicated by giving two characters and separating them "
"by a ``'-'``. For example, ``[abc]`` will match any of the characters "
"``a``, ``b``, or ``c``; this is the same as ``[a-c]``, which uses a range"
" to express the same set of characters. If you wanted to match only "
"lowercase letters, your RE would be ``[a-z]``."
msgstr ""
#: ../Doc/howto/regex.rst:92
msgid ""
"Metacharacters are not active inside classes. For example, ``[akm$]`` "
"will match any of the characters ``'a'``, ``'k'``, ``'m'``, or ``'$'``; "
"``'$'`` is usually a metacharacter, but inside a character class it's "
"stripped of its special nature."
msgstr ""
#: ../Doc/howto/regex.rst:97
msgid ""
"You can match the characters not listed within the class by "
":dfn:`complementing` the set. This is indicated by including a ``'^'`` "
"as the first character of the class; ``'^'`` outside a character class "
"will simply match the ``'^'`` character. For example, ``[^5]`` will "
"match any character except ``'5'``."
msgstr ""
#: ../Doc/howto/regex.rst:102
msgid ""
"Perhaps the most important metacharacter is the backslash, ``\\``. As "
"in Python string literals, the backslash can be followed by various "
"characters to signal various special sequences. It's also used to escape"
" all the metacharacters so you can still match them in patterns; for "
"example, if you need to match a ``[`` or ``\\``, you can precede them "
"with a backslash to remove their special meaning: ``\\[`` or ``\\\\``."
msgstr ""
#: ../Doc/howto/regex.rst:109
msgid ""
"Some of the special sequences beginning with ``'\\'`` represent "
"predefined sets of characters that are often useful, such as the set of "
"digits, the set of letters, or the set of anything that isn't whitespace."
msgstr ""
#: ../Doc/howto/regex.rst:114
msgid ""
"Let's take an example: ``\\w`` matches any alphanumeric character. If "
"the regex pattern is expressed in bytes, this is equivalent to the class "
"``[a-zA-Z0-9_]``. If the regex pattern is a string, ``\\w`` will match "
"all the characters marked as letters in the Unicode database provided by "
"the :mod:`unicodedata` module. You can use the more restricted "
"definition of ``\\w`` in a string pattern by supplying the "
":const:`re.ASCII` flag when compiling the regular expression."

"Locales are a feature of the C library intended to help in writing "
"programs that take account of language differences. For example, if "
"you're processing encoded French text, you'd want to be able to write "
"``\\w+`` to match words, but ``\\w`` only matches the character class "
"``[A-Za-z]`` in bytes patterns; it won't match bytes corresponding to "
"``é`` or ``ç``. If your system is configured properly and a French locale"
" is selected, certain C functions will tell the program that the byte "
"corresponding to ``é`` should also be considered a letter. Setting the "
":const:`LOCALE` flag when compiling a regular expression will cause the "
"resulting compiled object to use these C functions for ``\\w``; this is "
"slower, but also enables ``\\w+`` to match French words as you'd expect. "
"The use of this flag is discouraged in Python 3 as the locale mechanism "
"is very unreliable, it only handles one \"culture\" at a time, and it "
"only works with 8-bit locales. Unicode matching is already enabled by "
"default in Python 3 for Unicode (str) patterns, and it is able to handle "
"different locales/languages."

"This flag allows you to write regular expressions that are more readable "
"by granting you more flexibility in how you can format them. When this "
"flag has been specified, whitespace within the RE string is ignored, "
"except when the whitespace is in a character class or preceded by an "
"unescaped backslash; this lets you organize and indent the RE more "
"clearly. This flag also lets you put comments within a RE that will be "
"ignored by the engine; comments are marked by a ``'#'`` that's neither in"
" a character class or preceded by an unescaped backslash."
