Comments in newLISP source files can be converted to HTML documentation using only a few tags in comments. The newLISPdoc system is designed to use a minimum of tags and leave the tagged comments still readable.
newLISPdoc also generates an index page for all newLISP source files generated.
See here for the source of newLISPdoc . The program and this documentation are also part of the source distribution of newLISP since version 9.0. Since newLISP version 9.1 syntax highlighting is built into newlispdoc which is installed in the same directory as the main newLISP executable program. The script syntax.cgi is still available for web site installations, but is not required anymore for newlispdoc.
From within the directory where the modules are, execute with all module filenames to process on the commandline. For example to process the files mysql.lsp, odbc.lsp and sqlite3.lsp do:
newlispdoc mysql.lsp odbc.lsp sqlite.lsp
Or on Windows:
newlisp newlispdoc mysql.lsp odbc.lsp sqlite.lsp
This will generate index.html, mysql.lsp.html, odbc.lsp.html and sqlite.lsp.html all in the same directory, where the command was executed. The page index.html contains links to all other pages.
If the current directory contains the file newlispdoc.css, HTML output will be formatted accordingly. For a sample file see util/newlispdoc.css in the source distribution.
The command line flag -s can be supplied to additionally generate syntax highlighted HTML versions of the source files and put a link to the highlighted version of the source file on the documentation page:
newlispdoc -s mysql.lsp odbc.lsp sqlite.lsp newlispdoc -s *.lsp
The -d flag supplies a download link to the raw source:
newlispdoc -d *.lsp newlispdoc -s -d *.lsp
One or both options can be supplied.
Or on Windows:
newlisp newlispdoc -s mysql.lsp odbc.lsp sqlite.lsp
Since version 1.3 of newLISPdoc a file containing URLs of source file locations can be specified. This allows indexing and documenting of newLISP source code distributed on different sites:
newlispdoc -url file-with-urls.txt newlispdoc -s -url file-with-urls.txt
Or on Windows:
newlisp newlispdoc -url file-with-urls.txt newlisp newlispdoc -s -url file-with-urls.txt
http:// and file:// URLs can be used. Like with individual files, the -s switch can be specified to generate also syntax highlighted source files. A URL file contains one URL per line. No other information is allowed in the file. The following is a sample URL file:
http://asite.com/code/afile.lsp http://othersite.org/somefile.lsp file:///usr/home/joe/program.lsp
The last line shows a file URL from the local filesystem.
All generated files will be written to the current directory.
The following tags start at the beginning of a line with 2 semicolons and one space before the tag:
;; @module one word for module name ;; @index Title and URL for index page ;; @description one line description of the module ;; @location the original URL location of the source file ;; @version one line version info ;; @author one line for author info ;; @syntax one line syntax pattern ;; @param name description on one line ;; @return description on one line ;; @example multiline code example starting on next line
The only required tag is either the @module tag or alternatively the @index tag. If neither one tag is present in the file, it will not be processed. All other tags are optional. Only lines starting with ;; (2 semicolons) are processed. Program comment text which should not appear in the documentation should start with only one semicolon.
The one line description of the @description tag will be put under the module name on the index and module doc page. This and the @location where added in June 2007, and are not part of the newlispdoc program in the newLISP v. 9.1 release.
A function may have multiple @syntax tags each on consecutive lines.
The following is the only tag, which can be embedded anywhere in the text. Between the tag link specification and description is exactly one space:
@link link description
Custom tags can be made up by just prepending the custom name with a @. The text after the custom tag will be translated as usual, e.g. it may contain a @link tag. Like in most other tags, text is limited to the same line.
All words between <...> angle braces are displayed in italic. Internally newLISPdoc uses <em>,</em> tags for formatting. They should be used for parameter specs after the @param tag and in text referring to those parameters..
All words between single quotes ' ... ' are printed in monospace. Internally newLISPdoc uses <tt>,</tt> tags for formatting.
All other lines starting with 2 semicolons contain descriptive text. An empty line with only 2 semicolons at the beginning is a break between paragraphs of text.
Lines not starting with 2 semicolons are ignored by newLISPdoc. This allows doing code comments with just one semicolon.
If more formatting is required than what is offered by newLISPdoc, the following simple HTML tags and their closing forms may also be used: <h1>,<h2>,<h3>,<h4>, <i>,<em>,<b>,<tt>,<p>, <br>,<pre>,<center>,<blockquote> and <hr>.
newLISPdoc generates and index page for all modules documented. A special tag @index can be used to show a link on the index page to an index of other module collections. This way multilevel indices of modules can be created. To display a link to another module collection on the index page, create a file containing a @index and a @description link:
; - other-collection.txt - ;; @index OtherCollection http://example.com/modules ;; @description Modules from OtherCollection
Use one or more of these files on the newLISPdoc command line as any other source file:
newlispdoc -s other-collection.txt *.lsp
This will show the index entry for OtherCollection on the module index before listing all modules in *.lsp.
The following is the commented source of and example program followed by the pages generated in HTML:
;; @module example.lsp ;; @author John Doe, email@example.com ;; @version 1.0 ;; ;; This module is an example module for the newlispdoc ;; program, which generates automatic newLISP module ;; documentation. ;; @syntax (example:foo <num-repeat> <str-message>) ;; @param <num-repeat> The number of times to repeat. ;; @param <str-message> The message string to be printed. ;; @return Returns the message in <str-message> ;; ;; The function 'foo' repeatedly prints a string to ;; standard out terminated by a line feed. ;; ;; @example ;; (example:foo 5 "hello world") ;; => ;; "hello world" ;; "hello world" ;; "hello world" ;; "hello world" ;; "hello world" (context 'example) (define (foo n msg) (dotimes (i n) (println msg)) ) ;; See the @link http://example.com/example.lsp source .
Below the example.lsp.html and index.html page generated:
This module is an example module for the newlispdoc program, which generates automatic newLISP module documentation.
return: Returns the message in str-message
The function foo repeatedly prints a string to standard out terminated by a line feed.
See the source.(example:foo 5 "hello world") => "hello world" "hello world" "hello world" "hello world" "hello world"
Below the index page index.html which was generated. When more than one module is specified on the command line, the index page will show one link line for each module.
