.TH CPPI "1" "March 2013" "cppi 1.18" "User Commands"
.SH NAME
cppi \- indent the C preprocessor directives in FILE to reflect their nesting
.SH SYNOPSIS
.B cppi
[\fIFILE\fR]
.br
.B cppi
\fI-c \fR[\fIOPTION\fR] [\fIFILE\fR]...
.SH DESCRIPTION
.\" Add any additional description here
.PP
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 following
directive must correspond to the level of nesting of that directive.
With no FILE, or when FILE is \-, read standard input.
.TP
\fB\-a\fR, \fB\-\-ansi\fR
when checking, fail if text follows #else or #endif
.TP
\fB\-c\fR, \fB\-\-check\fR
set exit code, but don't produce any output
.TP
\fB\-l\fR, \fB\-\-list\-files\-only\fR
don't generate diagnostics about indentation;
print to stdout only the names of files that
are not properly indented
.TP
\fB\-m\fR, \fB\-\-max\-string\-length\fR=\fILENGTH\fR
fail if there is a double\-quoted string longer
than LENGTH; if LENGTH is 0 (the default),
then there is no limit
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
With the \fB\-c\fR option, don't write to stdout. Instead, check the
indentation of the specified files giving diagnostics for preprocessor
lines that aren't properly indented or are otherwise invalid.
.PP
Note that \fB\-\-ansi\fR without \fB\-\-check\fR does not correct the problem of
non\-ANSI text following #else and #endif directives.
.SS "The exit code will be one of these:"
.TP
0
all directives properly indented
.TP
1
some cpp directive(s) improperly indented, or
text follows #else/#endif (enabled with \fB\-\-check\fR \fB\-\-ansi\fR), or
a double\-quoted string is longer than the specified maximum
.TP
2
#if/#endif mismatch, EOF in comment or string
.TP
3
file (e.g. open/read/write) error
.PP
A pragma directive may have its `#' indented.
