Source code repository location

The latest version of Docbrowser can be found at Github:

https://github.com/lokedhs/docbrowser

Compatibility

The application has been tested on SBCL, CCL and CLISP. Please let me know of any issues on other Common Lisp implementations.

Starting the server

After loading the package, run the following command from the REPL:

(docbrowser:start-docserver)

This will start the docserver on port 8080. A different port number can also be given as an optional argument.

To access the docbrowser, point a web browser to http://localhost:8080/

Definitions are sorted by export status, category, package, and then by lexicographic order.

6.1 Exported definitions

6.1.1 Special variables

Special Variable: *begin-code*

The string that opens a script segment. The end of a script segment is specified by *END-CODE*.

Package

parser.lisp (file)

Special Variable: *current-content*

Package

Special Variable: *end-code*

6.1.2 Functions

Function: escape-string-all STRING S

Escapes all characters in STRING which aren’t in the 7-bit ASCII character set.

Package

docbrowser-template

Source

util.lisp (file)

Function: escape-string-minimal STRING S

Escape only #<, #>, and #& in STRING.

Package

docbrowser-template

Source

util.lisp (file)

Function: escape-string-minimal-plus-quotes STRING S

Like ESCAPE-STRING-MINIMAL but also escapes quotes.

Package

docbrowser-template

Source

util.lisp (file)

Function: exec-template-file FILE DATA STREAM &key BINARY ENCODING

Load and compile FILE and put it into the template cache if it was not already in the cache. Then run the template using DATA and write the output to STREAM.

Package

docbrowser-template

Source

template.lisp (file)

Function: parse-template STREAM &key BINARY ENCODING INCLUDE-ROOT-DIR

Parses and compiles the template defition given as STREAM. If BINARY
is NIL, the generated template will output its data as strings (using PRINC), otherwise the output will be converted to binary using the encoding specified by ENCODING. The binary output is the preferred
method as that will allow constant strings in the template to be
encoded during parsing instead of at runtime.

INCLUDE-ROOT-DIR is used to specify a base directory from where the "include" command will search for files.

The return value is a function that takes two arguments, DATA and OUTPUT. DATA is the data that will be used by the template, and OUTPUT is the output stream to which the result should be written.
