-*- Text -*- LINEDIT Linedit is a readline-style library written in Common Lisp that provides customizable line-editing for Common Lisp programs. Version 0.11 uses UFFI for foreign bindings, and is hence theoretically portable. The development and testing has so far been carried out on SBCL, however. Patches are welcome. The current input handling is only empirically correct -- which is a gentile way of saying "works on my box, dunno about yours". Once again: patches are welcome. For more information, and the latest version of Linedit visit the Linedit homepage: http://common-lisp.net/project/linedit/ Questions, feature requests, and bug-reports to [email protected]. USAGE ----- > (asdf:load-system :linedit) > (linedit:linedit :prompt "-> ") > (linedit:formedit :prompt1 "=> " :prompt2 "| ") Meta-H in the prompt display help. (Try ESC-H if your terminal misbehaves with meta-proper.) USING LINEDIT IN THE REPL (SBCL AND CCL ONLY) --------------------------------------------- Do (when (interactive-stream-p *standard-input*) (asdf:load-system :linedit) (funcall (intern "INSTALL-REPL" :linedit) ;; Keeps toplevel commands intact, etc. :wrap-current t ;; Should EOF quit after verification? :eof-quits t ;; Persistent history :history "~/.linedit_history")) in eg. your Lisp initialization file (~/.sbclrc for SBCL). INTERFACE --------- function INSTALL-REPL &key wrap-current eof-quits history killring Installs the Linedit at REPL. (SBCL and CCL only.) WRAP-CURRENT keeps current input handlers (eg. toplevel command processors) in place. If EOF-QUITS is true, EOF on *STANDARD-INPUT* causes the system to exit after verification. HISTORY and KILLRING can be pathname designators, in which case they indicate the file to use for history and killring persistence, respectively." function UNINSTALL-REPL Removes Linedit REPL input handler. (SBCL and CCL only.) function LINEDIT &rest keys &key prompt history killring Reads a single line of input with line-editing from standard input of the process and returns it as a string. Results are unspecified if *STANDARD-INPUT* has been bound or altered. PROMPT specifies the string to print to *STANDARD-OUTPUT* before starting the accept input. HISTORY and KILLRING can be pathname designators, in which case they indicate the file to use for history and killring persistence, respectively. Further keyword arguments to LINEDIT are an advanced and undocumented topic, but if you're willing to dive into sources you can eg. use multiple kill-rings not shared between different invocations of LINEDIT, or change the function responsible for providing input completion. function FORMEDIT &rest keys &key prompt1 prompt2 history killring Reads a single form (s-expession) of input with line-editing from standard input of the process and returns it as a string. Results are unspecified if *STANDARD-INPUT* has been bound or altered, or if *READTABLE* is not the standard readtable. PROMPT1 specifies the string to print to *STANDARD-OUTPUT* before starting the accept input. PROMPT2 specifies the string to print to *STANDARD-OUTPUT* when input spans multiple lines (ie. prefixing every but first line of input.) HISTORY and KILLRING can be pathname designators, in which case they indicate the file to use for history and killring persistence, respectively. Further keyword arguments to FORMEDIT are an advanced and undocumented topic, but if you're willing to dive into sources you can eg. use multiple kill-rings not shared between different invocations of FORMEDIT, or change the function responsible for providing input completion.
