twopre.tcl [-help] [-verbose]
[-strip] [-DEFINE macro] [-UNDEF macro] [infile [outfile]]
twopre
is used to precompile a tcl file. It does inlining of TCL source commands
(with proper nesting) and inlining of TK image create bitmap and image create photo
commands (i.e. replace the option -file with -data).
Comments can be removed
and the additional two_{define|undef|ifdef|ifndef|else|endif} commands are
processed.
If no outfile is given, twopre will write to stdout. Without
an infile, twopre will use stdin.
The parser tries to recognize TCL syntax
properly, but there are always ways to fool it. There is no way to reliably
tell TCL code from data without really evaluating a file. So what the parser
actually does is it looks for any occurence of two_ifdef, two_ifndef,
two_define or two_undef, considers them to be TCL commands and retrieves
their parameters.
See two_pre(n) for details on the commands.
twopre.tcl
recognizes the following options:
-h|-help- Display a short help message.
-v|-verbose- Be more verbose, i.e. report (on stderr) which files are currently beeing source'd.
-s|-strip- Remove comments and empty lines. However, this is done whithout respecting the context (just using a simple regular expression), so it may well break things!
-D|-DEFINE- Define a macro (well, macros should better be called flags here, but the C Preprocessor always refers to them as macros as well...). This will override any
two_defineortwo_undefin the code.-U|-UNDEF- Undefine a macro. This will override any
two_defineortwo_undefin the code.
You can use any abbreviation of the above listed options,
but you can't use the SysV-style concatenation of options (thus -v -s is not
equal to -vs).
-strip option if you really know what's
going on.
