# This is the default value (as of the time I wrote this) but I'm making
# it explicit since it needs to agree with the value used by clang-format.
# Thus, if we ever change the fish style to allow longer or shorter lines
# this should be changed (as well as the corresponding .clang-format file).
#
- key: LONG_LINE
value: 100
#
# The default limit for the length of variable names is 20. Long names are
# problematic but twenty chars results in way too many errors. So increase
# the limit to something more reasonable.
#
- key: LONG_VARIABLE_NAME
value: 30
#
# This allows us to avoid peppering our code with inline comments such as
#
# scoped_lock locker(m_lock); //!OCLINT(side-effect)
#
# Specifically, this config key tells oclint that the named classes have
# RAII behavior so the local vars are actually used.
#
- key: RAII_CUSTOM_CLASSES
value: scoped_lock scoped_buffer_t builtin_commandline_scoped_transient_t scoped_push
# We're slightly more persmissive regarding the total number of lines in a
# function. Default is 50.
- key: LONG_METHOD
value: 60
# We're slightly more persmissive regarding the number of non-comment
# lines in a function. Default is 30.
- key: NCSS_METHOD
value: 40
# We're willing to allow slighly more linearly independent paths through a
# function. Most of our code has a lot of `switch` blocks or consecutive
# `if` tests that are straightforward to interpret but which increase this
# metric. Default is 10.
- key: CYCLOMATIC_COMPLEXITY
value: 14
# We're willing to allow slighly more execution paths through a function.
# Default is 200.
- key: NPATH_COMPLEXITY
value: 300
disable-rules:
#
# A few instances of "useless parentheses" errors are meaningful. Mostly
# in the context of the `return` statement. Unfortunately the vast
# majority would result in removing parentheses that decreases
# readability. So we're going to ignore this warning and rely on humans to
# notice when the parentheses are truly not needed.
#
# Also, some macro expansions, such as FD_SET(), trigger this warning and
# we don't want to suppress each of those individually.
#
- UselessParentheses
#
# OCLint wants variable names to be at least three characters in length.
# Which would be fine if it supported a reasonable set of exceptions
# (e.g., "i", "j", "k") and allowed adding additional exceptions to match
# conventions employed by a project. Since it doesn't, and thus generates
# a lot of really annoying warnings, we're going to disable this rule.
#
- ShortVariableName
#
# This rule flags perfectly reasonable conditions like `if (!some_condition)`
# and is therefore just noise. Disable this rule.
#
- InvertedLogic
#
# The idea behind the "double negative" rule is sound since constructs
# like "!!(var & flag)" should be written as "static_cast<bool>(var &
# flag)". Unfortunately this rule has way too many false positives;
# especially in the context of assert statements. So disable this rule.
#
- DoubleNegative
#
# Avoiding bitwise operators in a conditional is a good idea with one
# exception: testing whether a bit flag is set. Which happens to be the
# only time you'll see something like `if (j->flags & JOB_CONSTRUCTED)`
# in fish source.
#
- BitwiseOperatorInConditional
#
# I don't think I've ever seen a case where assigning a value to a
# parameter inside the function body was unclear, let along dangerous or
# an error. This rule is therefore just noise. Disable this rule.
