NAME
cppi - indent the C preprocessor directives in FILE to reflect their
nesting
SYNOPSIS
cppi [FILE]
cppi -c [OPTION] [FILE]...
DESCRIPTION
Indent the C preprocessor directives in FILE to reflect their nesting
and ensure that there is exactly one space character between each #if,
#elif, #define directive and the following token, and write the result
to standard output. The number of spaces between the `#' and the fol‐
lowing directive must correspond to the level of nesting of that direc‐
tive. With no FILE, or when FILE is -, read standard input.
-a, --ansi
when checking, fail if text follows #else or #endif
-c, --check
set exit code, but don't produce any output
-l, --list-files-only
don't generate diagnostics about indentation; print to stdout
only the names of files that are not properly indented
-m, --max-string-length=LENGTH
fail if there is a double-quoted string longer than LENGTH; if
LENGTH is 0 (the default), then there is no limit
--help display this help and exit
--version
output version information and exit
With the -c option, don't write to stdout. Instead, check the indenta‐
tion of the specified files giving diagnostics for preprocessor lines
that aren't properly indented or are otherwise invalid.
Note that --ansi without --check does not correct the problem of
non-ANSI text following #else and #endif directives.
The exit code will be one of these:
0 all directives properly indented
1 some cpp directive(s) improperly indented, or text follows
#else/#endif (enabled with --check --ansi), or a double-quoted
string is longer than the specified maximum
2 #if/#endif mismatch, EOF in comment or string
3 file (e.g. open/read/write) error
A pragma directive may have its `#' indented.
