haddock \- documentation tool for annotated Haskell source code

.B haddock
.RI [ options ] " file" ...

This manual page documents briefly the
.B haddock
Extensive documentation is available in various other formats including DVI,
PostScript and HTML; see below.

.I file
is a filename containing a Haskell source module.
All the modules specified on the command line will be processed together.
When one module refers to an entity in another module being processed, the
documentation will link directly to that entity.

Entities that cannot be found, for example because they are in a module that
is not being processed as part of the current batch, simply will not be
hyperlinked in the generated documentation.
.B haddock
will emit warnings listing all the identifiers it could not resolve.

The modules should not be mutually recursive, as
.B haddock
does not like swimming in circles.

The programs follow the usual GNU command line syntax, with long
options starting with two dashes (`--').
A summary of options is included below.
For a complete description, see the other documentation.

\fB\-o \fIDIR\fP, \-\-odir=\fIDIR\fP
directory in which to put the output files

\fB\-i \fIFILE\fP, \-\-read-interface=\fIFILE\fP
read an interface from 

\fB\-D \fIFILE\fP, \-\-dump\-interface=\fIFILE\fP
dump an interface for these modules in  

\fB\-l \fIDIR\fP, \-\-lib=\fIDIR\fP
location of Haddock's auxiliary files

.BR \-h ", " \-\-html
Generate documentation in HTML format.
Several files will be generated into the current directory (or the specified
directory if the 
.B \-o
option is given), including the following:
.I index.html
The top level page of the documentation:
lists the modules available, using indentation to represent the hierarchy if
the modules are hierarchical.
.I haddock.css
The stylesheet used by the generated HTML.
Feel free to modify this to change the colors or layout, or even specify
your own stylesheet using the
.B \-\-css
.I module.html
An HTML page for each module.
.IR doc-index.html ", " doc-index-XX.html
The index, split into two (functions/constructors and types/classes, as per
Haskell namespaces) and further split alphabetically.

.B \-\-hoogle
output for Hoogle

produce index and table of contents in mshelp, mshelp2 or devhelp format 
(with \fI\-h\fP)

Include links to the source files in the generated documentation, where URL
is the base URL where the source files can be found.

\fB\-s \fPURL, \fB\-\-source\-module=\fPURL
Include links to the source files in the generated documentation, where URL
is a source code link for each module (using the %{FILE} or %{MODULE} vars).

Include links to the source files in the generated documentation, where URL
is a source code link for each entity (using the %{FILE}, %{MODULE} or %{NAME} vars).

URL for a comments link on the contents and index pages.
URL for a comments link for each module (using the %{MODULE} var).
URL for a comments link for each entity (using the %{FILE}, %{MODULE} or %{NAME} vars).
.BI \-\-css= FILE
Use the CSS
instead of the default stylesheet that comes with
.B haddock 
for HTML output. It should specify certain classes: see the default stylesheet for details.

\fB\-p \fIFILE\fP, \-\-prologue=\fIFILE\fP
Specify a file containing prologue text.

\fB\-t \fITITLE\fP, \-\-title=\fITITLE\fP
Use \fITITLE\fP as the page heading for each page in the documentation.
This will normally be the name of the library being documented.

The title should be a plain string (no markup please!).

\fB\-k \fINAME\fP, \-\-package=\fINAME\fP
Specify the package name (optional).

.BR \-n ", " \-\-no\-implicit\-prelude  
do not assume Prelude is imported

.BR \-d ", " \-\-debug
Enable extra debugging output.

.BR \-? ", " \-\-help
Display help.

.BR \-V ", " \-\-version
Display version.

.BR \-v ", " \-\-verbose
Verbose status reporting.

Use a separately-generated HTML contents page.

.B \-\-gen\-contents
Generate an HTML contents from specified  interfaces.

Use a separately-generated HTML index.

.B \-\-gen\-index
Generate an HTML index from specified interfaces.

.B \-\-ignore\-all\-exports   
Behave as if all modules have the ignore-exports atribute

Behave as if \fIMODULE\fP has the hide attribute.

The modules being processed depend on \fIPACKAGE\fP.
