NAME¶
autom4te - Generate files and scripts thanks to M4
SYNOPSIS¶
autom4te [OPTION]... [FILES]
DESCRIPTION¶
Run GNU M4 on the FILES, avoiding useless runs. Output the traces if tracing, the frozen file if freezing, otherwise the expansion of the FILES.
If some of the FILES are named 'FILE.m4f' they are considered to be M4 frozen files of all the previous files (which are therefore not loaded). If 'FILE.m4f' is not found, then 'FILE.m4' will be used, together with all the previous files.
Some files may be optional, i.e., will only be processed if found in the include path, but then must end in '.m4?'; the question mark is not part of the actual file name.
Operation modes:¶
- -h, --help
- print this help, then exit
- -V, --version
- print version number, then exit
- -v, --verbose
- verbosely report processing
- -d, --debug
- don't remove temporary files
- -o, --output=FILE
- save output in FILE (defaults to '-', stdout)
- -f, --force
- don't rely on cached values
- -W, --warnings=CATEGORY
- report the warnings falling in CATEGORY (comma-separated list accepted)
- -l, --language=LANG
- specify the set of M4 macros to use
- -C, --cache=DIRECTORY
- preserve results for future runs in DIRECTORY
- --no-cache
- disable the cache
- -m, --mode=OCTAL
- change the non trace output file mode (0666)
- -M, --melt
- don't use M4 frozen files
Languages include:¶

- obsolete features or constructions (default)
- override
- user redefinitions of Automake rules or variables
- portability
- portability issues (default in gnu and gnits modes)

- -I, --include=DIR
- append directory DIR to search path
Tracing:¶
- -t, --trace=MACRO[:FORMAT]
- report the MACRO invocations
- -p, --preselect=MACRO
- prepare to trace MACRO in a future run
Freezing:¶
- -F, --freeze
- produce an M4 frozen state file for FILES
FORMAT defaults to '$f:$l:$n:$%', and can use the following escapes:¶
- $$
- literal $
- $f
- file where macro was called
- $l
- line where macro was called
- $d
- nesting depth of macro call
- $n
- name of the macro
- $NUM
- argument NUM, unquoted and with newlines
- $SEP@
- all arguments, with newlines, quoted, and separated by SEP
- $SEP*
- all arguments, with newlines, unquoted, and separated by SEP
- $SEP%
- all arguments, without newlines, unquoted, and separated by SEP
SEP can be empty for the default (comma for @ and *, colon for %), a single character for that character, or {STRING} to use a string.
