Lutz, is that you @newlisp?

Edit: No, I assume this is you, but are you on as newlisp as well? Greetings from @taoeffect! :-D

[Lutz]

... yes, thats me. @newlisp for newLISP announcements and @lutz_mueller for everything else (probably not used much).

[itistoday]

(probably not used much).

You'll give into it, sooner or later, everyone does. </cliche> :-D

[m i c h a e l]

Just wanted to mention that I deleted my Twitter account a few days ago. I did this because a couple of my entries were “disappeared,” and I had lost confidence in Twitter.

I mention this because I didn’t want those individuals whom I was following to think I simply stopped following them :-)

Lutz,

Here's my take on the twitter.lsp (v0.3ax) which uses my linked? and command-line stuff. This way the script can be executed either by newlisp.exe on the commandline or after use of link.lsp.

Kind regards,
Bruce.

Code: Select all

; post, delete and see user and friends messages and followers on http://twitter.com
; February 12th, 2009, L.M.
; version 0.1
; version 0.2
;    added twitter seach
;    fields now separated by CR-LF
;    records now separated by CR-LF CR-LF
; version 0.3
;    eliminated spurious nil in search
;    added xml option to search
; version 0.4ax
;	better main-args handling. Now using linked? and command-line
;	not very graceful about failures, e.g. search without search term
; when no parameters are given, show help text

P.S. I'm not exactly sure where to post this.

On Unix OSs you could see "/usr/bin/newlisp" or similar in (args 0), so the following might be safer:

Code: Select all

(if (find "newlisp" (args 0) 1) ... )

although most Unix folks wouldn't use link.lsp, because they would have to compile newLISP anyway, if not running Mac OX X or Ubuntu Linux.

Also, isn't there a way on Windows to combine source with a batch file? There is something here: http://www.newlisp.org/index.cgi?page=Code_Snippets but I am not sure if it still works. It might take care of the 'main-args' issue.

What is the code to use a Windows OS Shell command to execute a script?

[cormullion]

Open Command Prompt, and type:

Code: Select all

newlisp "script"

where script is the name of the script.

To see more options, type:

Code: Select all

newlisp -h

I've just found a Windows machine and tried this. Yay, my first time! :)

(The manual gets it spot on, too... :))
