ExtUtils::Mkbootstrap(3pm) Perl Programmers Reference Guide ExtUtils::Mkbootstrap(3pm)NAME
ExtUtils::Mkbootstrap - make a bootstrap file for use by DynaLoader
SYNOPSIS
"Mkbootstrap"
DESCRIPTION
Mkbootstrap typically gets called from an extension Makefile.
There is no "*.bs" file supplied with the extension. Instead, there may be a *_BS file which has code for the special cases, like posix for
berkeley db on the NeXT.
This file will get parsed, and produce a maybe empty @DynaLoader::dl_resolve_using array for the current architecture. That will be
extended by $BSLOADLIBS, which was computed by ExtUtils::Liblist::ext(). If this array still is empty, we do nothing, else we write a .bs
file with an @DynaLoader::dl_resolve_using array.
The *_BS file can put some code into the generated "*.bs" file by placing it in $bscode. This is a handy 'escape' mechanism that may prove
useful in complex situations.
If @DynaLoader::dl_resolve_using contains "-L*" or "-l*" entries then Mkbootstrap will automatically add a dl_findfile() call to the
generated "*.bs" file.

ExtUtils::Typemaps::Cmd - Quick commands for handling typemaps
SYNOPSIS
From XS:
INCLUDE_COMMAND: $^X -MExtUtils::Typemaps::Cmd
-e "print embeddable_typemap(q{Excommunicated})"
Loads "ExtUtils::Typemaps::Excommunicated", instantiates an object, and dumps it as an embeddable typemap for use directly in your XS file.
DESCRIPTION
This is a helper module for ExtUtils::Typemaps for quick one-liners, specifically for inclusion of shared typemaps that live on CPAN into
an XS file (see SYNOPSIS).
For this reason, the following functions are exported by default:
EXPORTED FUNCTIONS
embeddable_typemap
Given a list of identifiers, "embeddable_typemap" tries to load typemaps from a file of the given name(s), or from a module that is an
"ExtUtils::Typemaps" subclass.
Returns a string representation of the merged typemaps that can be included verbatim into XS. Example:
print embeddable_typemap(
"Excommunicated", "ExtUtils::Typemaps::Basic", "./typemap"
);
This will try to load a module "ExtUtils::Typemaps::Excommunicated" and use it as an "ExtUtils::Typemaps" subclass. If that fails, it'll
try loading "Excommunicated" as a module, if that fails, it'll try to read a file called Excommunicated. It'll work similarly for the
second argument, but the third will be loaded as a file first.
After loading all typemap files or modules, it will merge them in the specified order and dump the result as an embeddable typemap.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:

Hi all...
Well guys and gals, I jumped in at the deep end and found things that PERL cannot do by default.
Many tricky terminal escape codes are not catered for so I had to create workarounds.
One thing I searched for was this:

Well, guys I saw a question about GOTO for Python.
So this gave me the inspiration to attempt a GOTO function for 'dash', (bash and ksh too).
