private |
Retrieves all the text between matching open and close parentheses. Given a string of lines and a regular expression string, retrieve all the text following the expression and between opening punctuation symbols like (, [, or {, and the matching close-punctuation symbol. This properly nested occurrences of the punctuations, so for the text like printf(a(), b(c())); a call to _GetTextInside(text, r'printf\(') will return 'a(), b(c())'. start_pattern must match string having an open punctuation symbol at the end. Args: text: The lines to extract text. Its comments and strings must be elided. It can be single line and can span multiple lines. start_pattern: The regexp string indicating where to start extracting the text. Returns: The extracted text. None if either the opening string or ending punctuation could not be found.

error | |||
) |
Logs an error for each line containing bad characters. Two kinds of bad characters: 1. Unicode replacement characters: These indicate that either the file contained invalid UTF-8 (likely) or Unicode replacement characters (which it shouldn't). Note that it's possible for this to throw off line numbering if the invalid UTF-8 occurred adjacent to a newline. 2. NUL bytes. These are problematic for some tools. Args: filename: The name of the current file. lines: An array of strings, each representing a line of the file. error: The function to call with any errors found.

function_state, | |||
error | |||
) |
Reports for long function bodies. For an overview why this is done, see: https://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Write_Short_Functions Uses a simplistic algorithm assuming other style guidelines (especially spacing) are followed. Only checks unindented functions, so class members are unchecked. Trivial bodies are unchecked, so constructors with huge initializer lists may be missed. Blank/comment lines are not counted so as to avoid encouraging the removal of vertical space and comments just to get through a lint check. NOLINT *on the last line of a function* disables this check. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. function_state: Current function name and lines in body so far. error: The function to call with any errors found.

def roslint.cpplint.CheckForIncludeWhatYouUse | ( | filename, | |
clean_lines, | |||
include_state, | |||
error, | |||
io = codecs |
|||
) |
Reports for missing stl includes. This function will output warnings to make sure you are including the headers necessary for the stl containers and functions that you use. We only give one reason to include a header. For example, if you use both equal_to<> and less<> in a .h file, only one (the latter in the file) of these will be reported as a reason to include the <functional>. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. include_state: An _IncludeState instance. error: The function to call with any errors found. io: The IO factory to use to read the header file. Provided for unittest injection.

def roslint.cpplint.CheckForMultilineCommentsAndStrings | ( | filename, | |
clean_lines, | |||
linenum, | |||
error | |||
) |
Logs an error if we see /* ... */ or "..." that extend past one line. /* ... */ comments are legit inside macros, for one line. Otherwise, we prefer // comments, so it's ok to warn about the other. Likewise, it's ok for strings to extend across multiple lines, as long as a line continuation character (backslash) terminates each line. Although not currently prohibited by the C++ style guide, it's ugly and unnecessary. We don't do well with either in this lint program, so we warn about both. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. error: The function to call with any errors found.

def roslint.cpplint.CheckForNonStandardConstructs | ( | filename, | |
clean_lines, | |||
linenum, | |||
nesting_state, | |||
error | |||
) |
Logs an error if we see certain non-ANSI constructs ignored by gcc-2. Complain about several constructs which gcc-2 accepts, but which are not standard C++. Warning about these in lint is one way to ease the transition to new compilers. - put storage class first (e.g. "static const" instead of "const static"). - "%lld" instead of %qd" in printf-type functions. - "%1$d" is non-standard in printf-type functions. - "\%" is an undefined character escape sequence. - text after #endif is not allowed. - invalid inner-style forward declaration. - >? and <? operators, and their >?= and <?= cousins. Additionally, check for constructor/destructor style violations and reference members, as it is very convenient to do so while checking for gcc-2 compliance. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. nesting_state: A NestingState instance which maintains information about the current stack of nested blocks being parsed. error: A callable to which errors are reported, which takes 4 arguments: filename, line number, error level, and message

def roslint.cpplint.CloseExpression | ( | clean_lines, | |
linenum, | |||
pos | |||
) |
If input points to ( or { or [ or <, finds the position that closes it. If lines[linenum][pos] points to a '(' or '{' or '[' or '<', finds the linenum/pos that correspond to the closing of the expression. TODO(unknown): cpplint spends a fair bit of time matching parentheses. Ideally we would want to index all opening and closing parentheses once and have CloseExpression be just a simple lookup, but due to preprocessor tricks, this is not so easy. Args: clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. pos: A position on the line. Returns: A tuple (line, linenum, pos) pointer *past* the closing brace, or (line, len(lines), -1) if we never find a close. Note we ignore strings and comments when matching; and the line we return is the 'cleansed' line at linenum.

def roslint.cpplint.Error | ( | filename, | |
linenum, | |||
category, | |||
confidence, | |||
message | |||
) |
Logs the fact we've found a lint error. We log where the error was found, and also our confidence in the error, that is, how certain we are this is a legitimate style regression, and not a misidentification or a use that's sometimes justified. False positives can be suppressed by the use of "cpplint(category)" comments on the offending line. These are parsed into _error_suppressions. Args: filename: The name of the file containing the error. linenum: The number of the line containing the error. category: A string used to describe the "category" this bug falls under: "whitespace", say, or "runtime". Categories may have a hierarchy separated by slashes: "whitespace/indent". confidence: A number from 1-5 representing a confidence score for the error, with 5 meaning that we are certain of the problem, and 1 meaning that it could be a legitimate construct. message: The error message.

Definition at line 5327 of file cpplint.py.
def roslint.cpplint.FilesBelongToSameModule | ( | filename_cc, | |
filename_h | |||
) |
Check if these two filenames belong to the same module. The concept of a 'module' here is a as follows: foo.h, foo-inl.h, foo.cc, foo_test.cc and foo_unittest.cc belong to the same 'module' if they are in the same directory. some/path/public/xyzzy and some/path/internal/xyzzy are also considered to belong to the same module here. If the filename_cc contains a longer path than the filename_h, for example, '/absolute/path/to/base/sysinfo.cc', and this file would include 'base/sysinfo.h', this function also produces the prefix needed to open the header. This is used by the caller of this function to more robustly open the header file. We don't have access to the real include paths in this context, so we need this guesswork here. Known bugs: tools/base/bar.cc and base/bar.h belong to the same module according to this implementation. Because of this, this function gives some false positives. This should be sufficiently rare in practice. Args: filename_cc: is the path for the .cc file filename_h: is the path for the header path Returns: Tuple with a bool and a string: bool: True if filename_cc and filename_h belong to the same module. string: the additional prefix needed to open the header file.
