NAME¶
hxincl - expand included HTML or XML files
SYNOPSIS¶
hxincl [
-x ] [
-f ] [
-s name=subst ] [
-s name=subst ]... [
-b base ] [
file-or-URL ]
DESCRIPTION¶
The
hxincl command copies an HTML or XML file to standard output, looking
for comments with a certain structure. Such a comment is replaced by the file
whose name is given as the attribute of the directive. For example:
...<!-- include "foo.html" -->...
will be replaced by the content of the file
foo.html. It is important to
note that you must quote filenames if they contain white space.
The comment is replaced by
<!-- begin-include "foo.html" -->
before the included text and
<!-- end-include "foo.html" -->
after it. These comments make it possible to run
hxincl on the resulting
file again to update the inclusions.
Single quotes are allowed instead of double quotes. And if the file name
contains no spaces, the quotes may also be omitted.
OPTIONS¶
The following options are supported:
- -x
- Use XML conventions: empty elements are written with a
slash at the end: <IMG />.
- -b base
- Sets the base URL for resolving relative URLs. By default
the file given as argument is the base URL.
- -f
- Removes the comments after including the files. This means
hxincl connot be run on the resulting file later to update the
inclusions. (Mnemonic: final or frozen.)
- -s name=substitution
- Include a different file than the one mentioned in the
directive. If the comment is
<!-- include "name" -->
the file substitution is included instead. The option -s may
occur multiple times.
OPERANDS¶
The following operand is supported:
- file-or-URL
- The name of an HTML or XML file or the URL of one. If
absent, standard input is read instead.
EXIT STATUS¶
The following exit values are returned:
- 0
- Successful completion.
- > 0
- An error occurred in the parsing of one of the HTML or XML
files.
ENVIRONMENT¶
To use a proxy to retrieve remote files, set the environment variables
http_proxy or
ftp_proxy. E.g.,
http_proxy="http://localhost:8080/"
BUGS¶
Assumes UTF-8 as input. Doesn't expand character entities. Instead pipe the
input through
hxunent(1) and
asc2xml(1) to convert it to UTF-8.
Remote files (specified with a URL) are currently only supported for HTTP.
Password-protected files or files that depend on HTTP "cookies" are
not handled. (You can use tools such as
curl(1) or
wget(1) to
retrieve such files.)
