|-C||The source file is a C source file. It is assumed that it will have the dependencies resolved by the cpp(1) command. The same include semantics as the cpp(1) command will be employed. This is the default. This is short-hand for --language=c|
This option may be used to specify the language of the source file.
Know names include C, M4, optimistic and roff.
The optimistic language will take on almost anything. It accepts an CW]include keyword in any case, including mixed, with leading white space, but at most one leading punctuation character. It assumes that the filename follows the include keyword and does not contain white space, and does not start or end with punctuation characters (it strips off any it may find). The rest of the line is ignored. The drawback is that it will sometimes recognise commands and other text as unintended include directives, hence the name. This is often used to recognise include directives in a wide variety of assembler input.
|-Roff||The source file is a *roff source file. It is assumed that it will have the dependencies resolved by the roffpp(1) command. The same include semantics as the roffpp(1) command will be employed. This is short-hand for --language=roff|
|-Verbose||Tell what is happening.|
|-Ipath||Specify include path, a la cc(1).|
Any directories you specify with
-I options before the
-I- option are searched only for the case of #include "file";
they are not searched for #include <file>.
If additional directories are specified with -I options after the -I-, these directories are searched for all #include directives. (Ordinarily all -I directories are used this way.)
In addition, the -I- option inhibits the use of the current directory (where the current input file came from) as the first search directory for #include "file". There is no way to override this effect of -I-. With -I. you can specify searching the directory which was current when c_incl was invoked. That is not exactly the same as what the preprocessor does by default, but it is often satisfactory.
The -I- option does not inhibit the use of the standard system directories for header files. Thus, -I- and -No_System are independent.
|This option may be used to allow absolute paths in the output. This is usually the default.|
|This option may be used to exclude absolute paths from the output.|
|For files included using a #include filename.h directive, ignore the file if it cannot be found.|
|For files included using a #include filename.h directive, print the file name even if the file cannot be found. This is the default (it probably needs to be built).|
|For files included using a #include filename.h directive, print a fatal error if the file cannot be found.|
|For files included with a #include <filename.h> directive, ignore the file if it cannot be found. This is the default (it was probably ifdefed out).|
|For files included with a #include <filename.h> directive, print the file name even if the file cannot be found.|
|For files included with a #include <filename.h> directive, print a fatal error if the file cannot be found.|
|If the file named on the command line cannot be found, behave as if the file were found, but was empty.|
|If the file named on the command line cannot be found, print a fatal error message. This is the default.|
|This option may be used to request that newlines in the output are escaped with backslash (\) characters.|
|-Help||Give information on how to use c_incl.|
|This option may be used to nominate include file names which are not to be used.|
|-VERSion||Tell what version of c_incl is being run.|
|This option may be used to tell c_incl about include files which dont exist yet. This is because they are interior to the dependency graph, but cook(1) hasnt finished walking it yet. Often used with Cooks [interior-files] function. (Note: the filename list has an arbitrary number of files; it ends at the next option or end-of-line, so you need to be careful where you put the input filename.)|
|Do not search the /usr/include directory. By default this is searched last. This option implies the -No_Absolute_Paths option, unless explicitly contradicted.|
|-CAche||This option may be used to turn caching on. This is the default.|
|This option may be used to turn caching off.|
|This option may be used to print a string before any of the filenames are printed. It will not be printed if no file names are printed.|
|This option may be used to have c_incl quote filenames. This permits filenames to contain characters which are special to Cook, including spaces.|
|This option may be used to print a string after all of the filenames are printed. It will not be printed if no file names are printed.|
|This option may be used to specify the output file. Defaults to the standard output if not set.|
|This option will give a fatal error if a #include filename.h directive is used. This is necessary when you are using Cooks search_list functionality to stitch together a baseline and a private work area.|
|This option may be used to specify that nested include files are to be scanned, so that their includes may also be discovered. This is the default.|
|This option may be use to specify that nested include files are not to be scanned. This option is recommended for use with the Cook cascade-for recipes. This option implies -No_Cache, unless a -Cache option is specified.|
|This option may be used to remove path prefixes from the included filenames. May be used more than once. This is necessary when you are using Cooks search_list functionality to stitch together a baseline and a private work area; usually as [prepost "-rlp=" "" [search_list]]|
|This option may be used to specify that leading redundant dot directories are to be removed from paths before processing. This is the default.|
|This option may be used to specify that leading redundant dot directories need not be removed from paths before processing. (Some path flattening may still occur.)|
|-Substitute_Leading_Path from to|
|This option may be used to modify path prefixes from the included filenames. May be used more than once. This is necessary when you are performing heterogeneous builds in the same directory tree. By using an arch variable to hold the architecture, and placing each architectures objects in a separate directory tree, this option may be used as -slp [arch] "[arch]" (The outer quotes protect from Cook, the inner quotes protect from the shell.) If you need more intricate editing, used sed(1).|
All options may be abbreviated; the abbreviation is documented as the upper case letters, all lower case letters and underscores (_) are optional. You must use consecutive sequences of optional letters.
All options are case insensitive, you may type them in upper case or lower case or a combination of both, case is not important.
For example: the arguments "-help", "-HEL" and "-h" are all interpreted to mean the -Help option. The argument "-hlp" will not be understood, because consecutive optional characters were not supplied.
Options and other command line arguments may be mixed arbitrarily on the command line.
The GNU long option names are understood. Since all option names for c_incl are long, this means ignoring the extra leading -. The "--option=value" convention is also understood.
The caching mechanism use by the c_incl program caches the results of searching files for include files (in a file called .c_inclrc in the current directory). The cache is only refreshed when a file changes.
The use of this cache has been shown to dramatically increase the performance of the c_incl program. Typically, only a small proportions files in a project change between builds, resulting in a very high cache hit rate.
When using caching, always use the same command line options, otherwise weird and wonderful things will happen.
The .c_inclrc file is a binary file. If you wish to rebuild the cache, simply delete this file with the rm(1) command. Being a binary file, the .c_inclrc file is not portable across machines or operating systems, so you will need to delete it when you move your sources. It is a binary file for performance.
Accesses to the .c_inclrc file use file locking, so recipies using c_incl need not use the single-thread clause.
The c_incl command will exit with a status of 1 on any error. The c_incl command will only exit with a status of 0 if there are no errors.
