|
ca65html is an assembler source to HTML converter. It is very useful if you
|
|
want to publish your assembler sources in the web.

<sect>Overview<p>
|
|
|
|
ca65html converts assembler source files written for use with the <tt/<htmlurl
|
|
url="ca65.html" name="ca65">/ crossassembler into HTML. It is a standalone
|
|
tool written in Perl, and as such it does not understand the structure of
|
|
assembler sources in the same depth as ca65 does, so it may fail in very rare
|
|
cases. In all other cases it generates very nice output.

<sect1>Command line options in detail<p>
|
|
|
|
Here is a description of all the command line options:
|
|
|
|
<descrip>
|
|
|
|
<tag><tt>--bgcolor c</tt></tag>
|
|
|
|
Set the background color. The argument c must be a valid HTML color, usually
|
|
given as RGB triplet in the form <tt/#rrggbb/, where r, g and b are the
|
|
respective red, green and blue parts as two digit hex values. The default is
|
|
<tt/#FFFFFF/ (white). This color is used in the <tt/<body>/ tag of the
|
|
generated HTML output.
|
|
|
|
|
|
<tag><tt>--colorize</tt></tag>
|
|
|
|
Colorize the output. The converter outputs processor instructions, assembler
|
|
control commands and comments in different colors.
|
|
|
|
While this make the output look very nice, it generates invalid HTML,
|
|
because using colors in a <tt/<pre>/ environment is not allowed.
|
|
However, most browsers display it well, and it is used by several other
|
|
tools, so it's up to you.
|
|
|
|
|
|
<tag><tt>--commentcolor c</tt></tag>
|
|
|
|
Set the color used for comments. The argument c must be a valid HTML color,
|
|
usually given as RGB triplet in the form <tt/#rrggbb/, where r, g and b are
|
|
the respective red, green and blue parts as two digit hex values. The
|
|
default is <tt/#B22222/ (red).
|
|
|
|
Note that this option has no effect if <tt/--colorize/ is not also given.
|
|
|
|
|
|
<tag><tt>--crefs</tt></tag>
|
|
|
|
Generate references to the C file, when a <tt/.dbg/ command is found with a
|
|
file name. The converter assumes that the C source was also converted into
|
|
HTML (for example by use of <tt/c2html/), has the name <tt/file.c.html/, and
|
|
lives in the same directory as the assembler file. If the <tt/.dbg/
|
|
directive specifies a line, a link to the correct line in the C file is
|
|
generated, using a label in the form <tt/linexxx/, as it is created by
|
|
<tt/c2html/ by use of the <tt/-n/ option.
|
|
|
|
|
|
<tag><tt>--commentcolor c</tt></tag>
|
|
|
|
Set the color used for assembler control commands. The argument c must be a
|
|
valid HTML color, usually given as RGB triplet in the form <tt/#rrggbb/,
|
|
where r, g and b are the respective red, green and blue parts as two digit
|
|
hex values. The default is <tt/#228B22/ (green).
|
|
|
|
Note that this option has no effect if <tt/--colorize/ is not also given.
|
|
|
|
|
|
<tag><tt>--cvttabs</tt></tag>
|
|
|
|
Convert tabs in the input into spaces in the output, assuming the standard
|
|
tab width of 8. This is useful if the <tt/--linenumbers/ option is used to
|
|
retain the indentation.
|
|
|
|
|
|
<tag><tt>--help</tt></tag>
|
|
|
|
Print the command line option summary shown above.
|
|
|
|
|
|
<tag><tt>--htmldir dir</tt></tag>
|
|
|
|
Specify an output directory for the generated HTML files.
|
|
|
|
|
|
<tag><tt>--indexcols n</tt></tag>
|
|
|
|
Use n columns on the index page. This option has no effect if used without
|
|
<tt/--indexpage/.
|
|
|
|
|
|
<tag><tt>--indexname name</tt></tag>
|
|
|
|
Use another index file name instead of <tt/index.html/. This option has no
|
|
effect if used without <tt/--indexpage/.
|
|
|
|
|
|
<tag><tt>--indexpage</tt></tag>
|
|
|
|
Causes the converter to generate an index page listing all label names and
|
|
exports found in the converted files.
|
|
|
|
|
|
<tag><tt>--indextitle title</tt></tag>
|
|
|
|
Use "title" as the title of the index page. This option has no effect if
|
|
used without <tt/--indexpage/.
|
|
|
|
|
|
<tag><tt>--keywordcolor c</tt></tag>
|
|
|
|
Set the color used for processor instructions. The argument c must be a
|
|
valid HTML color, usually given as RGB triplet in the form <tt/#rrggbb/,
|
|
where r, g and b are the respective red, green and blue parts as two digit
|
|
hex values. The default is <tt/#A020F0/ (purple).
|
|
|
|
Note that this option has no effect if <tt/--colorize/ is not also given.
|
|
|
|
<tag><tt>--linelabels</tt></tag>
|
|
|
|
Generate a label for each line using the name <tt/linexxx/ where xxx is the
|
|
number of the line.
|
|
|
|
Note: The converter will not make use of this label. Use this option if you
|
|
have other HTML pages referencing the converted assembler file.
|
|
|
|
|
|
<tag><tt>--linenumbers</tt></tag>
|
|
|
|
Generate line numbers on the left side of the output.
|
|
|
|
|
|
<tag><tt>--linkstyle n</tt></tag>
|
|
|
|
Influences the style used when generating links for imports. If n is zero
|
|
(the default), the converter creates a link to the actual symbol if it is
|
|
defined somewhere in the input files. If not, it creates a link to the
|
|
<tt/.import/ statement. If n is one, the converter will always generate a
|
|
HTML link to <tt/.import/ statement.
|
|
|
|
|
|
<tag><tt>--replaceext</tt></tag>
|
|
|
|
Replace the file extension of the input file instead of appending <tt/.html/
|
|
when generating the output file name.
|
|
|
|
|
|
<tag><tt>--textcolor c</tt></tag>
|
|
|
|
Set the color for normal text. The argument c must be a valid HTML color,
|
|
usually given as RGB triplet in the form <tt/#rrggbb/, where r, g and b are
|
|
the respective red, green and blue parts as two digit hex values. The
|
|
default is <tt/#000000/ (black). This color is used in the <tt/<body>/
|
|
tag of the generated HTML output.
|
|
|
|
|
|
<tag><tt>--verbose</tt></tag>
|
|
|
|
Increase the converter verbosity. Without this option, ca65html is quiet
|
|
when working. If you have a slow machine and lots of files to convert, you
|
|
may like a little bit more progress information.

|
<sect>Peculiarities<p>
|
|
|
|
<sect1>Cross links<p>
|
|
|
|
Since ca65html is able to generate links between modules, the best way to use
|
|
it is to supply all modules to it in one run, instead of running each file
|
|
separately through it.
|
|
|
|
|
|
<sect1>Include files<p>
|
|
|
|
For now, ca65html will not read files included with <tt/.include/. Specifying
|
|
the include files as normal input files on the command line works in many
|
|
cases.
|
|
|
|
|
|
<sect1>Conversion errors<p>
|
|
|
|
Since ca65html does not really parse the input, but does most of its work
|
|
applying text patterns, it doesn't know anything about scoping and advanced
|
|
features of the assembler. This means that it may miss a label may choose the
|
|
wrong color for an item in rare cases. Since it's just a tool for displaying
|
|
sources in a nice form, I think that's ok. Anyway, if you find a conversion
|
|
problem, you can send me a short piece of example input code. If possible, I
|
|
will fix it.
|
|
|
|
|
|
<sect1>Colorization<p>
|
|
|
|
While having colors in the output looks really nice, it has two drawbacks:
|
|
|
|
<enum>
|
|
|
|
<item>The output is not standard compliant HTML, because <tt/<font>/
|
|
tags are use in a <tt/<pre>/ environment. This works with all browsers
|
|
I've tested, but it may not work with the one you're using.
|
|
|
|
<item>Since lots of <tt/<font>/ tags are created in the output, the size
|
|
of the output file will literally explode. This seems to be the price, you
|
|
have to pay for color...
|
|
|

|
<sect>Bugs/Feedback<p>
|
|
|
|
If you have problems using the converter, if you find any bugs, or if you're
|
|
doing something interesting with the assembler, I would be glad to hear from
|
|
you. Feel free to contact me by email (<htmlurl url="mailto:uz@cc65.org"
