Parser.__addToken

__addToken(toktype, toktext, srow, scol, line)

Private method used to add a token to our list of tokens.

toktype: the type of the token (int)
toktext: the text of the token (string)
srow: starting row of the token (int)
scol: starting column of the token (int)
line: logical line the token was found (string)

Parser.__tokeneater

__tokeneater(toktype, toktext, (srow, scol), (erow, ecol), line)

Private method called by tokenize.tokenize.

toktype: the type of the token (int)
toktext: the text of the token (string)
srow: starting row of the token (int)
scol: starting column of the token (int)
erow: ending row of the token (int)
ecol: ending column of the token (int)
line: logical line the token was found (string)

Parser.parse

parse(text)

SourceStat (Constructor)

SourceStat()

Constructor

SourceStat.dedent

dedent(tok)

Public method used to decrement the indentation level.

tok: the token to be processed (Token)

SourceStat.dump

dump()

Public method used to format and print the collected statistics.

SourceStat.getCounter

getCounter(id, key)

Public method used to get a specific counter value.

id: id of the counter (string)
key: key of the value to be retrieved (string)

Returns:: the value of the requested counter (int)

SourceStat.inc

inc(key, value=1)

Public method used to increment the value of a key.

key: the key to be incremented
value: the increment (int)

SourceStat.indent

indent(tok)

Public method used to increment the indentation level.

tok: a token (Token, ignored)

SourceStat.push

push(identifier, row)

Public method used to store an identifier.

identifier: the identifier to be remembered (string)
row: the row, the identifier is defined in (int)

**kw: list of key, value pairs

analyze

analyze(filename, total)

Module function used analyze the source of a Python file.

filename: name of the Python file to be analyzed (string)
total: dictionary receiving the overall code statistics

Returns:: a statistics object with the collected code statistics (SourceStat)

main

main()

Modules main function used when called as a script.

This function simply loops over all files given on the commandline and collects the individual and overall source code statistics.

summarize

summarize(total, key, value)

Module function used to collect overall statistics.

total: the dictionary for the overall statistics
key: the key to be summarize
value: the value to be added to the overall statistics

Returns:: the value added to the overall statistics
