def cpplint.CheckForBadCharacters | ( | filename, | |
lines, | |||
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.

def cpplint.CheckForFunctionLengths | ( | filename, | |
clean_lines, | |||
linenum, | |||
function_state, | |||
error | |||
) |
Reports for long function bodies. For an overview why this is done, see: http://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 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.
Definition at line 4376 of file cpplint.py.
def 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.
Definition at line 1519 of file cpplint.py.
def cpplint.CheckForNewlineAtEOF | ( | filename, | |

clean_lines, | |||
linenum, | |||
nesting_state, | |||
error | |||

Check rules that are applicable to #include lines. Strings on #include lines are NOT removed from elided line, to make certain tasks easier. However, to prevent false positives, checks applicable to #include lines in CheckLanguage must be put here. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. include_state: An _IncludeState instance in which the headers are inserted. error: The function to call with any errors found.

def cpplint.CheckInvalidIncrement | ( | filename, | |
clean_lines, | |||
linenum, | |||
error | |||
) |
Checks for invalid increment *count++. For example following function: void increment_counter(int* count) { *count++; } is invalid, because it effectively does count++, moving pointer, and should be replaced with ++*count, (*count)++ or *count += 1. 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.

Checks rules from the 'C++ language rules' section of cppguide.html. Some of these rules are hard to test (function overloading, using uint32 inappropriately), but we do the best we can. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. file_extension: The extension (without the dot) of the filename. include_state: An _IncludeState instance in which the headers are inserted. nesting_state: A _NestingState instance which maintains information about the current stack of nested blocks being parsed. error: The function to call with any errors found.

def cpplint.CheckPosixThreading | ( | filename, | |
clean_lines, | |||
linenum, | |||
error | |||
) |
Checks for calls to thread-unsafe functions. Much code has been originally written without consideration of multi-threading. Also, engineers are relying on their old experience; they have learned posix before threading extensions were added. These tests guide the engineers to use thread-safe functions (when using posix directly). 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.

file_extension, | |||
nesting_state, | |||
error | |||
) |
Checks rules from the 'C++ style rules' section of cppguide.html. Most of these rules are hard to test (naming, comment style), but we do what we can. In particular we check for 2-space indents, line lengths, tab usage, spaces inside code, etc. Args: filename: The name of the current file. clean_lines: A CleansedLines instance containing the file. linenum: The number of the line to check. file_extension: The extension (without the dot) of the filename. nesting_state: A _NestingState instance which maintains information about the current stack of nested blocks being parsed. error: The function to call with any errors found.

def 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. 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.
Definition at line 1246 of file cpplint.py.
def 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 980 of file cpplint.py.
def 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.
