NAME

6       cppi  -  indent  the C preprocessor directives in FILE to reflect their
7       nesting
8

SYNOPSIS

10       cppi [FILE]
11       cppi -c [OPTION] [FILE]...
12

DESCRIPTION

14       Indent the C preprocessor directives in FILE to reflect  their  nesting
15       and  ensure that there is exactly one space character between each #if,
16       #elif, #define directive and the following token, and write the  result
17       to  standard output.  The number of spaces between the `#' and the fol‐
18       lowing directive must correspond to the level of nesting of that direc‐
19       tive.  With no FILE, or when FILE is -, read standard input.
20
21       -a, --ansi
22              when checking, fail if text follows #else or #endif
23
24       -c, --check
25              set exit code, but don't produce any output
26
27       -l, --list-files-only
28              don't  generate  diagnostics  about indentation; print to stdout
29              only the names of files that are not properly indented
30
31       -m, --max-string-length=LENGTH
32              fail if there is a double-quoted string longer than LENGTH;   if
33              LENGTH is 0 (the default), then there is no limit
34
35       --help display this help and exit
36
37       --version
38              output version information and exit
39
40       With the -c option, don't write to stdout.  Instead, check the indenta‐
41       tion of the specified files giving diagnostics for  preprocessor  lines
42       that aren't properly indented or are otherwise invalid.
43
44       Note  that  --ansi  without  --check  does  not  correct the problem of
45       non-ANSI text following #else and #endif directives.
46
47   The exit code will be one of these:
48       0      all directives properly indented
49
50       1      some cpp  directive(s)  improperly  indented,  or  text  follows
51              #else/#endif  (enabled  with --check --ansi), or a double-quoted
52              string is longer than the specified maximum
53
54       2      #if/#endif mismatch, EOF in comment or string
55
56       3      file (e.g. open/read/write) error
57
58       A pragma directive may have its `#' indented.
