Note
The Opcode tags borrowed from
SequenceMatcher
class in thedifflib
standard Python module.Each tuple takes the form:
(tag, location, a, b)tag:
Value Meaning ‘replace’ same element in both, but different values. ‘delete’ remove value b ‘insert’ insert value a ‘equal’ same values in both location is a tuple that can take the following forms:
Tuple form Description (0) Global file level context (e.g., both files are the same) (1, stanza) Stanzas are the same, or completely different (no shared keys) (2, stanza, key) Key level, indicating Possible alternatives:

ksconf.conf.parser module¶
Parse and write Splunk’s .conf files
According to this doc:
https://docs.splunk.com/Documentation/Splunk/7.2.3/Admin/Howtoeditaconfigurationfile
- Comments must start at the beginning of a line (#)
- Comments may not be after a stanza name or on an attribute’s value
- Supporting encoding is UTF-8 (and therefore ASCII too)

cont_handler
(iterable, continue_re=re.compile('^(.*)\\\\$'), breaker='\n')¶ Look for trailing backslashes (“\”) which indicate a value for an attribute is split across multiple lines. This function will group such lines together, and pass all other lines through as-is. Note that the continuation character must be the very last character on the line, trailing whitespace is not allowed.
Parameters: - iterable (iter) – lines from a configuration file
- continue_re – regular expression to detect the continuation character
- breaker – joining string when combining continued lines into a single string. Default ‘\n’
Returns: lines of text
Return type: str

-

parse_conf
(stream, profile={'dup_key': 'overwrite', 'dup_stanza': 'exception', 'keep_comments': True, 'strict': True}, encoding=None)¶ Parse a .conf file. This is a wrapper around
parse_conf_stream()
that allows filenames or stream to be passed in.Parameters: - stream (str, file) – the path to a configuration file or open file-like object to be parsed
- profile – parsing configuration settings
- encoding – Defaults to the system default, “uft-8”
Returns: a mapping of the stanza and attributes. The resulting output is accessible as [stanaza][attribute] -> value
Return type: dict
-
ksconf.conf.parser.
parse_conf_stream
(stream, keys_lower=False, handle_conts=True, keep_comments=False, dup_stanza='exception', dup_key='overwrite', strict=False)¶
-
ksconf.conf.parser.
section_reader
(stream, section_re=re.compile('^[\\s\\t]*\\[(.*)\\]\\s*$'))¶ This generator break a configuration file stream into sections. Each section contains a name and a list of text lines held within that section.
Sections that have no entries must be preserved. Any lines before the first section are send back with the section name of None.
Parameters: - stream (file) – configuration file input stream
- section_re – regular expression for detecting stanza headers
Returns: sections in the form of (section_name, lines_of_text)
Return type: tuple
-
ksconf.conf.parser.
smart_write_conf
(filename, conf, stanza_delim='\n', sort=True, temp_suffix='.tmp')¶

splitup_kvpairs
(lines, comments_re=re.compile('^\\s*[#;]'), keep_comments=False, strict=False)¶ Break up ‘attribute=value’ entries in a configuration file.
Parameters: - lines (iter) – the body of a stanza containing associated attributes and values
- comments_re – Regular expression used to detect comments.
- keep_comments (bool, optional) – Should comments be preserved in the output. Defaults to False.
- strict (bool, optional) – Should unknown content in the stanza stop processing. Defaults to False allowing “junk” to be silently ignored for a best-effort parse.
Returns: iterable of (attribute,value) tuples

update_conf
(conf_path, profile={'dup_key': 'overwrite', 'dup_stanza': 'exception', 'keep_comments': True, 'strict': True}, encoding=None, make_missing=False)¶ Bases:
object
Context manager that allows for simple in-place updates to conf files. This provides a simple dict-like interface for easy updates.
Usage example:
with update_conf("app.conf") as conf: conf["launcher"]["version"] = "1.0.2" conf["install"]["build"] = 33
Parameters: - conf_path (str) – Path to
.conf
file to be edited. - profile (dict) – Parsing settings and strictness profile.
- encoding (str) – encoding to use for file operations.
- make_missing (bool) – When true, a new blank configuration file will be created with the updates rather than raising an exception.
