shlex — Simple lexical analysis — Python 3

  1. ilanguages, (for example, in run control files for Python applications) or for parsing quoted strings. The shlex module defines the following functions: shlex.split (s, comments=False, posix=True)
  2. The shlex module defines the following class:. class shlex.shlex([instream [, infile [, posix]]])¶. A shlex instance or subclass instance is a lexical analyzer object. The initialization argument, if present, specifies where to read characters from. It must be a file-/stream-like object with read() and readline() methods, or a string (strings are accepted since Python 2.3)
  3. shlex - Lexical analysis of shell-style syntaxes. ¶. Lexical analysis of shell-style syntaxes. The shlex module implements a class for parsing simple shell-like syntaxes. It can be used for writing your own domain specific language, or for parsing quoted strings (a task that is more complex than it seems, at first)
  4. # strip C-style comments # shlex will handle the python/shell style comments for us line = re.sub(self.comment_pattern, self._comment_replacer, line) # expand shortcuts and aliases line = self._expand(line) # split on whitespace lexer = shlex.shlex(line, posix=False) lexer.whitespace_split = True # custom lexing tokens = self._split_on_punctuation(list(lexer)) return token

  7. python, windows : parsing command lines with shlex. When you have to split a command-line, for example to call Popen, the best practice seems to be. subprocess.Popen (shlex.split (cmd), The shlex class makes it easy to write lexical analyzers for simple syntaxes resembling that of the Unix shell.

Inspired by ordereddict, this is a packaging of an improved shlex module for Python 2 that handles Unicode properly. Shlex is A lexical analyzer class for simple shell-like syntaxes. If you've found your way here, you probably already know that the standard shlex doesn't handle Unicode prior to Python 3 (see bug 1170 for details). Since Python 2.7.3 however, it accepts unicode objects. Sadly, it still does not handle non-ascii chars ein bisschen komplizierter als die andere Lösung, aber es funktioniert Nur unwesentlich, so, und die lex.commenters bit ist eigentlich etwas, dass meine Antwort nicht zu tun. +1 für einen anderen Weg, um git-r-dun. Angefangen habe ich mit den Quellcode der shlex.split-Funktion aus der python-source und einfach optimiert mit der Liste der Zitate Zeichen node-shlex is a Node.js module for quoting and parsing shell commands. The API was inspired by the shlex module from the Python Standard Library. However, the Python implementation is fairly complex, and supports a confusing matrix of modes that is not replicated here. node-shlex always operates in what the Python module calls POSIX mode The shlex class makes it easy to write lexical analyzers for simple syntaxes resembling that of the Unix shell. This will often be useful for writing minilanguages, (for example, in run control files for Python applications) or for parsing quoted strings. The shlex module defines the following functions: shlex.split(s, comments=False, posix=True) Python: split command line into pieces as the shell does - shlex.split () Sometime, for example when you use subprocess you might want to run an external program avoiding the invocation of the shell. For that you need to have the external command in pieces, not in a single long string. So what if you have the command as a string

Python besteht aus dem Interpreter, der den Sprachkern implementiert und aus einer Sammlung von Standard-Modulen, ohne die sich kaum Skripts schreiben lassen, die wirklich Arbeit verrichten. So implementiert das Modul » os« eine Schnittstelle zum Betriebssystem . Viele Methoden sind auf allen Betriebssystemen gleichermaßen verfügbar, manche unterscheiden sich zwischen Unix (Linux, Mac OS X. This approach has behavior very similar to the standard shell parsing. Extract key value pairs in Python 3 using shlex and regex. import re import shlex def regex_kv_pairs (text: str, value_sep==): Parse key-value pairs from a shell-like text with regex.

  5. The subprocess.run method in Python is pretty powerful, as it allows you to run shell commands within python itself. This helps in limiting all code to python itself without the need to have additional shell script code in separate files. It can be, however, quite tricky to correctly tokenize shell commands in a python list. You can use the shlex.split() method to tokenize simple shell.

This will often be useful for writing minilanguages, e.g. in run control files for Python applications. shlex ([stream]) A shlex instance or subclass instance is a lexical analyzer object Yes. I think that the main use of shlex is really to parse a line into chunks with a way to embed spaces; it?s intended to parse a program command line (?prog --blah value stillthesamevalue arg samearg?), but not necessarily a full shell line (with & and | and whatnot). When people have a line containing & and |, then they need a shell to execute it, so they would not call shlex.split but. Patch to mention shlex.quote() in the `subprocess` module's Frequently Used Arguments Warning box. Could perhaps be a separate Note, but that could be clutter-y.
