Command line from TiddlyWiki

[stevesuny]

Hello,

Was wondering if anyone has built an interface to the command line from tiddlywiki. 

For example, given a tiddler tagged tag1 tag2 tag3, I might want to run these commands at the command line, from within tiddlywiki. 

grep tag1 ~/Documents/filename| grep tag2 | grep tag3  |cut -f3 > ~/Documents/outputs/grepped.lines

wc -l ~/Documents/outputs/grepped.lines > grepped.lines.linecount

and be able to import grepped.lines and grepped.lines.linecount as tiddlers.

Doable?

I suppose I could generate the commands in a tiddler, export it as a text file, and use it as a script, but was hoping to do it in one step.

Thanks,

//steve.

I would really like to be able to run a bash script from a tiddlywiki, but I haven't figured out how yet.

As I wrote that I realised that it should be possible to use the child_process module in node to run console commands, so we may be able to make widget that does that. That doesn't take care of the browser-vs-node scope problems, which would require something like what I made for robbie to pass the command between the browser and the main node process and then reply with the output.

I suppose that you want the command line interface because you're comfortable with unix-style commands. But you might be able to do what you want without having to use a separate language.

This will create tiddlers that count the number of tiddlers marked 'Widget' and store it in a tiddler. You could modify for tag[tag1]tag[tag2] or whatever you wanted to count:

<$button>
<$wikify name="cnt" text="<$count filter='[tag[Widgets]]'/>">
<$action-createtiddler $basetitle="Current Widget Count"  text=<<cnt>>/>
Record number of widgets
</$wikify>
</$button>

Good luck,
Mark

Steve,

Did you see this discussion on Windows Command line via a custom export (save in download) export and loop that processes?, Its quite easy to create a new exporter to do this and I am sure the same method can be used in other OS's.

Regards
Tony

P.S.

I was also going to share this custom export idea for your Spreadsheet tool to re-export.

I'm pretty sure, that you don't want to run arbitrary scripts form untrusted sources on your computer, if the browser visits any page.

A word of advice:

That is precisely the attack vector to which you (we) are most vulnerable.  You cannot know or ascertain whether your friends are or have been exposed to malware *designed* to use that precise attack vector.  Attackers and their code *rely* on us behaving that way.

Be safe. Take extreme care with ALL sources - even more care with friends.

I very much doubt its so dire. Since TW is NOT interactive the only ingress is if you compromised your own site. I DID mine by using an open FTP, never aqain.

So, do you want the 5 minute argument, or the full half hour? -:)
