Project File Options
You can specify various options and information for your project in the meta-data of your project file. Quoting from the Markdown Meta-Data page (and not intending to give an example of the meta-data fields supported by FORD):
Meta-data consists of a series of keywords and values defined at the beginning of a markdown document like this:
Title: My Document
Summary: A brief description of my document.
Authors: Waylan Limberg
John Doe
Date: October 2, 2007
blank-value:
base_url: http://example.com This is the first paragraph of the document.The keywords are case-insensitive and may consist of letters, numbers, underscores and dashes and must end with a colon. The values consist of anything following the colon on the line and may even be blank.
If a line is indented by 4 or more spaces, that line is assumed to be an additional line of the value for the previous keyword. A keyword may have as many lines as desired. [Note that these must be spaces and not tabs.]
The first blank line ends all meta-data for the document. Therefore, the first line of a document must not be blank. All meta-data is stripped from the document prior to any further processing by Markdown.
Project file options will be overriden by Command Line Options.See ./example/example-project-file.md for a sample project file.
N.B.!: Markdown comments must not appear within the meta data section! Typical markdown commenting strategies may be used within the markdown body of the project file, BUT NOT WITHIN THE META-DATA SECTION! After declaring meta-data HTML block comments of the form
<!-- This is a multi line
comment!
wow
-->or markdown phony link comments may be used:
[comment 1 goes here, this will declare a phony link target. Just make sure not to reference the null anchor]:#
The options which can be specified in the meta-data are listed below. Defaults are included in the description, if they exist.
Information about your project.
The name of the project's chatroom on Gitter, which can then be displayed using the Gitter sidecar.
The licenses under which the documentation is released. Options are:

- by-nd: Creative Commons attribution, no derivatives
- by-sa: Creative Commons attribution, share-alike
- by-nc: Creative Commons attribution, non-commercial
- by-nc-nd: Creative Commons attribution, non-commercial, non derivatives

The path to a custom favicon which will be used by the HTML documentation. If left blank, it will default to an icon for FORD. Evaluated relative to the location of the project file.
The name of this project. (default: Fortran Project)
The URL of the BitBucket repository for this project.
A URL from which to download the source or binaries for this project.
The URL of the Github repository for this project.
The URL of the Gitlab repository for this project.
The Sourceforge repository for this project.
The URL at which the documentation will be available. If
left blank then relative URLs will be used for links. This can be used within
any documentation with the macro |url|. (default: blank, i.e. relative links)
The homepage for this project.
A summary of the description of your project. If present it will be printed in a "Jumbotron" element at the top of the documentation index page. This will be processed by Markdown before being used.
Information about the author.
The name of the person(s) or organization who wrote this project.
A brief description of the author. You could provide biographical details or links to other work, for example. This will be processed by Markdown before being used.
A picture of or avatar for the author.
The author's BitBucket page.
The author's email address.
The author's Facebook profile.
The author's Github page.
The author's Google+
The author's LinkedIn profile.
The author's Twitter.
The author's website.
Settings specifying where to look (and not to look) for documentation.
Directories whose contents should not be included in documentation. Each excluded directory must be on its own line. Provide the relative path to directory from the top level project file.
Directories in which the C preprocessor searches for any #includeed files, such as headers. These
directories will also be searched for files loaded using Fortran's intrinsic include statement. Each
directory must appear on its own line. Evaluated relative to the location of the project file.
A directory containing any images or other content which
you will use or link to in your documentation. This will be placed at the root
of your documentation file-tree, with the name "media". The URL of this
directory can be accessed within your documentation using the macro |media|.
Evaluated relative to the location of the project file.
The directory relative to which any "included" Markdown files' paths are specified. (default: directory containing the project file.) Evaluated relative to the location of the project file.
A directory containing markdown files to be processed into individuals pages within the documentation. See Writing Pages for details. Evaluated relative to the location of the project file.
The directories where the source-files are to be found for this project. These must not be a subdirectory of the output_dir (see below). Multiple directories can be listed, each on their own line. Evaluated relative to the location of the project file. (default: ./src)
Source files which should not be included in documentation. Each excluded file must be on its own line. Provide only the file-name, not the full path.
File extensions which will be read by FORD for documentation. Each extension must be on its own line. These extensions are only for free-form code; see below for fixed-form extensions. (default: f90, f95, f03, f08, f15, F90, F95, F03, F08, F15)
Non-Fortran source files from which documentation should be extracted (see here). Multiple values may be provided, each on its own line. Each entry should consist of the extension of the file-type to be documented, a space, and then the character(s) designating a comment within such a file. Only single-line comments are supported.
Experimental: You may optionally specify the
Pygments lexer to use when
applying syntax-highlighting to the file, as an additional argument
after the comment character. This should take the form of the module
being imported relative to
pygments.lexer. E.g. fortran.FortranLexer or c_cpp.CLexer. This
feature should not be considered stable and the behaviour may change
in future releases.
File extensions which will be read by FORD for documentation, with the files containing fixed-form code. (default: f, for, F, FOR)
If false, fixed-form code lines are read in their entire length. Otherwise anything after the 72nd column is ignored. (default: true)
If desired, your source files can be passed through an arbitrary preprocessor before being analysed by FORD.
File extensions which should be preprocessed prior to further analysis. If the extension is not specified in extensions or fixed_extensions then the file will be assumed to be free-form. (default: F90, F95, F03, F08, F15, F, FOR)
Macros to be provided to the C preprocessor when applying it to source files. Can take the form
mac-name or mac-name=mac-value. Each macro must appear on its own line.
If set to 'true', then any files with extensions in fpp_extensions will be passed through the specified preprocessor, CPP by default. (default: true)
The preproccessor command to use on files with extensions in fpp_extensions. Can include flags as needed. Macros and include paths specified in the project file will automatically be appended using the CPP interface, which is fairly standard. (default: cpp -traditional-cpp -E)
The symbol(s) following an exclaimation mark which
designates that a comment contains documentation. For excample, if the docmark
was !, comments would then be designated by !!. It should not be
the same as any other docmark. (default: !)
The symbol(s) following an exclaimation mark which
designate that the following set of comments, until the end of the block, are all
documentation. This mark needs only to be used at the beginning of the block,
after which all regular comments will be treated as documentation. For excample,
if the docmark was *, comments would then be designated by !*. An example of
such a block of documentation is provided.
!* This is an example.
! Here is another line of comments.
!
! History
! ----------
! * 1/1/2000 Created
subroutine blah()
end subroutine blahIt should not be the same symbol as any other docmark. (default: *)
The symbol(s) following an exclaimation mark which
designates that a comment contains documentation preceding the code which
it is documenting. For excample, if the docmark
was >, comments would then be designated by !>. It should not be
the same as any other docmark. (default: >)
The symbol(s) following an exclaimation mark which
designate the start of a block of documentation preceding the code which
it is documenting and that all further comments within this block will be
treated as documentation. For example, if the predocmark_alt
was #, comments would then be designated by !#. It should not be
the same as any other docmark. (default: |)
Settings specifying how to process documentation and what information to display in the output.
List of aliases in the form key = replacement. In the documentation |key| can then be used
as shorthand for replacement. For example:
alias: ford = FORD (the Fortran documentation generator)
euler = \exp(i \pi) + 1 = 0
This code uses |ford|.
Did you know Euler's identity is $$|euler|$$?
becomes:
This software uses FORD (the Fortran documentation generator).
Did you know Euler's identity is $$\exp(i \pi) + 1 = 0$$?
Three aliases are pre-defined: |url| for the project URL, |media| for the media directory and |page| for the page_dir.
Aliases can currently only be defined in the project file, and not in individual docstrings
A Python datetime format to be
used if the date and time at which the documentation was generated is printed in the documentation footer.
(default: %Y-%m-%dT%H:%M:%S.%f%z)
The path to a custom style-sheet which can be used to modify the appearance of the output. Evaluated relative to the location of the project file.
How much documentation should be printed. Options are 'public', 'private', 'protected', or any combination of those three. Each choice must be on its own line. If 'none' is present, then nothing will be displayed other than the programs, modules, and procedures contained within source files (i.e. procedures within modules will not be displayed). These choice can be overridden for a specific item using the documentation meta data, and those settings will be inherited by any items they contain. (default: 'public' and 'protected')
A list of modules (and their external documentation) which are not included in the project.
An entry takes the form module_name:url where module_name is its name as
it would appear in a use statement, and url is the location of its documentation. Any entity
which uses this module will provide a link to the external documentation in the same way that
it would provide a link to the documentation of a module in the project.
Any extra types of variables which FORD should look for. This can be useful when using, for example, the PETSc library. Each variable type must be on its own line.
This flag toggles visibility of the source files in FORD documentation output. If set to true, the individual files will be listed and all contents will be shown on a file page. If false, procedures will still show the names of the files they are defined in, but there will be no way to access the contents of the file itself. For showing the code definitions for individual procedures, modules, and derived types, see source. (default: true)
If true then convert all non-string and non-comment source code to lower case prior to
analyzing. (default: false)
The path to a JavaScript file containing settings for MathJax. This might be used to, e.g., define TeX macros.
The name of any Markdown extensions which you wish to be used when parsing your documentation. For example, 'markdown.extensions.toc'. Note that Markdown-Extra, CodeHilite, and Meta-Data are loaded by default.
If true then will print the date and time of creation, using the specified date format, in the footer of
each page of documentation. (default: false)
If false then the local variables, derived types, etc. within public procedures will not be included in documentation. This is equivalent to setting display: none in the documentation meta data of each procedure.
It can be overriden locally in the
documentation meta data.
(default: false)
The name of the particular revision of your code/documentation, to be printed in the footer below the license and copyright year.
If true then add a search feature to the documentation. This can be time-consuming, so you may
want to turn it off for large projects. Note that this process can be sped up if the
lxml library is installed. (default: true)
The order in which to display entities (variables, procedures, etc.) in the documentation. Options are (default: src)
-
src: Order which they occur in source code -
alpha: Alphabetical order. -
permission: Display public first, then protected, then private. Within these categories, items are displayed in the same order as they occur in the source code. -
permission-alpha: Display public first, then protected, then private. Within these categories, items are displayed in alphabetical order. -
type: Sort variables (and functions) by type. For each time, items are displayed in the same order as they occur in the source code/ -
type-alpha: Sort variables (and functions) by type. Within these categories, items are displayed in alphabetical order.
If set to 'true', then the syntax-highlighted source code will be displayed at the bottom of the
documentation page for each procedure, program, and derived type. This behaviour can be overridden
for a given item using the
documentation meta data.
FORD may not be able to extract the source code in all cases; see
here
for details. To hide source files themselves, see incl_src. Note that this substantially increases run-time. (default: false)
The version name/number of your project.
The year to display in the copyright notice. (default: the current year)
FORD can generate call-trees, dependency diagrams, and inheritance diagrams will be produced for the project. These require Graphviz to be installed. Note that this can increase run-time substantially. The following graphs are produced:
- For each module:
- a graph showing the modules which it
uses and, if a submodule, the (sub)modules it is descended from - a graph showing which modules
useand which submodules descend from this one
- a graph showing the modules which it
- For each type:
- a graph showing all type which it descends from or contains as a component
- a graph showing all types which descend from or contain as a component this type
- For each procedure:
- a graph showing all procedures called by this procedure and (for interfaces) any procedures which it provides an interface to
- a graph showing all procedures which call this one or provide and interface to it
- For each program:
- a graph showing the modules which are
used by the program - a graph showing the procedures called by the program
- a graph showing the modules which are
- A graph showing all module
usedependencies on the module list page - A graph showing the inheritance structure of all derived types (and their use as components of other types) on the type list page
- A graph showing the call-tree for all programs and procedures on the procedure list page
Note that, at present, call-trees only work for procedural programming and will not identify any calls to type-bound procedures. Call-trees are not supposed to show intrinsic procedures. However, intrinsic procedures and even keywords may appear in a grey node on the graph. This means that it this procedure was not known (or overlooked) by the developers. Please report this is a bug. (default: false)
If true then edges connecting nodes in the graphs will be assigned various colours. This can make large graphs
easier to read. Americans, please note that the proper spelling has
been used here. (default: false)
If set to 'true' then graphs are produced of call trees, dependency
structures, and inheritance diagrams. This behaviour can be overridden
for a given item in the code using the
documentation meta data. (default:
false)
The maximum number of recursions to make when analysing graph structures. For large projects, producing graphs can be prohibitively time-consuming and the graphs confusing and unreadable if full recursion is used, so you may wish to set the maximum to be only a few levels. (default: 10000)
The maximum number of nodes which may be displayed in a graph. For large projects, graphs become unreadable if they contain too many nodes. A graph's depth will be reduced to keep the number of nodes below this maximum or, if the even a depth of one would result in more nodes than the maximum, it will be restructured to give a clearer visualisation. (default: 100000000)
Where documentation should be written to.
The directory where the project output will be placed. Any content already present there will be deleted. Evaluated relative to the location of the project file. (default: ./doc)
A directory where, if it is specified and graphs is set to true, SVG and graphviz copies
of all graphs for your project will be placed. Note that name mangling is applied to the filenames.
Evaluated relative to the location of the project file.
Miscellaneous options determining how FORD is run and its output.
Allows FORD to crash and display a Python backtrace if an error is encountered when parsing a file.
The number of CPUs to in multithreading. 0 indicates that the code should be run in serial. (default: number of cores on the computer)
If 'true', FORD will suppress all output documenting its progress. (default: false)
If 'true', FORD will print warning messages for any undocumented items which it encounters and any time it can not find the source code for some item where it is requested as part of the documentation. (default: false)
