amacleod 30-Jun-2008 [2583] | I'm trying to copy some text from the position found iwhile parsing a document. I'm using something like: rule: [some digit copy text to newline] (--where "digit has ben defined as all digits 0 to 9) This copies eveerything after the digit. How would I copy the digit itself as well? |
Brock 30-Jun-2008 [2584x2] | would it not simply be.... to some digit instead of what you have above? I'll start playing around and see if I can be of any help (if you haven't already figured it out) |
Not as easy as it seemed to be. Will take more time than I have right now. | |
amacleod 30-Jun-2008 [2586] | Is there a difference between using "to" and "thru" |
[unknown: 5] 30-Jun-2008 [2587] | yes |
Graham 30-Jun-2008 [2588] | is this block parsing? |
[unknown: 5] 30-Jun-2008 [2589] | to goes to the point and thru includes the point |
amacleod 30-Jun-2008 [2590x2] | No |
So to newline does not include the newline? | |
[unknown: 5] 30-Jun-2008 [2592] | no it wouldn't |
Graham 30-Jun-2008 [2593x2] | rule: [ digit copy text to newline skip ] parse stuff [ some rule ] |
digits: [ some digit ] rule: [ digits ... ] | |
amacleod 30-Jun-2008 [2595] | Graham, the digit String would be included in the copied text with this? |
Graham 30-Jun-2008 [2596x3] | nope |
because it matches digit and the cursor moves on | |
past the digit | |
amacleod 30-Jun-2008 [2599] | Right. Anyway to capture the digit? |
[unknown: 5] 30-Jun-2008 [2600] | you can always do something like set n number! |
Graham 30-Jun-2008 [2601x2] | rule: [ copy d thru digits .... ] |
He's using string parsing .. not block parsing | |
[unknown: 5] 30-Jun-2008 [2603] | yeah can't use set then. |
amacleod 30-Jun-2008 [2604] | I'll try that Graham. Thanks |
Graham 30-Jun-2008 [2605x3] | or |
non-digits: complement digit parse [ copy digit-text to non-digits copy text to newline skip ] | |
and correct syntax helps :) | |
[unknown: 5] 30-Jun-2008 [2608x2] | >> str: "193920347REBOL ROCKS!^/" == "193920347REBOL ROCKS!^/" >> parse str compose [some (charset "0123456789") text: copy text thru newline] == true >> text == "REBOL ROCKS!^/" |
Something like that? | |
Brock 30-Jun-2008 [2610] | he was looking for the number and the string though. |
amacleod 30-Jun-2008 [2611x2] | No I have a text document with section numbers in front: 2. Hello 2.1 Hello Again 2.1.1 Hello already 3. Goodbye I want the section number inclued in hte copy |
It need not be included in hte same copy just as long as I can record it. | |
[unknown: 5] 30-Jun-2008 [2613] | So you just want each line then really? |
amacleod 30-Jun-2008 [2614x2] | Well it gets a little more complicated. some parts of the docment will be multilined. |
I thought it would be a simple thing that I was missing. I may need to re-think the formatting of the document. | |
[unknown: 5] 30-Jun-2008 [2616x2] | So even if something is multiline you would still want each line of the multiline correct? |
Or do you mean a multiline might looks something like this: 2.1 Hello Goodbye Where the second line doesn't have the preceeding number? | |
amacleod 30-Jun-2008 [2618] | Yes and formating may need to be retained |
[unknown: 5] 30-Jun-2008 [2619] | Ahhh yes that gets a bit more complicated. |
amacleod 30-Jun-2008 [2620] | Paul, while you are there... I was considering using Tretbase for this project |
[unknown: 5] 30-Jun-2008 [2621] | Excellent choise ;-) |
amacleod 30-Jun-2008 [2622] | Let me briefly explain where I'm going to see if you think its workable or perhaps a there is a better solution |
[unknown: 5] 30-Jun-2008 [2623] | k |
amacleod 30-Jun-2008 [2624x5] | I trying to put a set of Fire department related materials online. THey are now in pdf |
I'm converting them to text and reformatting them to parse | |
I want to hold each section in a seperate database record | |
So I can index for keywords and search and read only thse sections I need. | |
Photos and diagrams will also be stored. | |
[unknown: 5] 30-Jun-2008 [2629x4] | Well, TRETBASE 1.0 is the only finished product right now. So the only available TRETBASE app is 1.0 which is really not a multi-user solution. |
It might work for you if you not in need of multi-user (simultaenous access) | |
The next version of TRETBASE which is in work is multi-user and supports indexing. | |
But not finished. | |
