search and replace in tiddlers

[Mohammad]

Is there any way to search and replace in

Tiddlers

• text
• field value

for example search foo and replace with bar?

Do you mean across the whole of a TiddlyWiki?

Or just within a Tiddler?

Using filters you can test for particular values in fields SEARCH and use a button and action widget to setfield values REPLACE either for one tiddler or a batch of tiddlers.

If your field contains multiple values you may need to use the list operators to change one only in a list.

Global search and replace can be done opening the whole wiki in a text editor but you must be careful not to change the wrong values. Backup if doing this.

AFAIK, unless there's some brand-new operators, you can't actually replace text *inside* of tiddler text or fields. For that you'll need some 3rd party macro or widget.

I belive what you say to be generaly true yet recall an auto tag or auto l8nk plugin that scans text to find and change things.

Hmmmm

Just in tiddler.

Is these any existing macro to do that?

Mohammad,

There is an additional plugin for search and replace in code mirror. In the regular editor and text areas the browser search and replace can be used, and browser plugins found that help.

For large and complex tiddlers i prefer to use a browser plugin to open the text area in an external editor like notepad++ which has superior search and replace like including linefeed and tabs.

I believe the visual editor also has a search and replace.

Hi Mohammad,

https://danielorodriguez.com/TW5-searchNreplace/  or Stephens Kimmels http://skplugins.tiddlyspot.com/#FindReplace both working in the tiddler editor.

You are always busy, having good ideas. I enjoy it very much.

Thanks Birthe.

Thanks for your kind words! I gonna to be among the Tiddlywiki Noble Prize winners :-)  (the best joke of 2019!!)

Tony,

 I am looking to find a way to replace a word/phrase using Tiddler Commander!

But seems not straightforward at all!!

So, I ignore it and will wait to see when TW  itself supports such feature.

The command mode from the CodeMirror plugin with CodeMirror Keymap: vim 

works quite lovely with

:%s/foo/bar/gc

Even more delicious is that yanks work across the tiddlers, ie yy to yank a line in one tiddler, open a different tiddler and p to paste

Heck, even :sort to sort all lines in the tiddlers work

Good stuff!

Best,

tony

Yep,

 That is really handy! Specially when you write codes

Thanks Tnoy for the hint!

Here's a javascript macro you can play with in a safe place. It's just a think javascript macro wrapped around the underlying javascript system, so I'm sure it could be improved.

Invoke like:

<<regexpsub "(\w+)\s(\w+)" '$2, $1' "John Doe">>

Parameters regtext (which can be a regular expression, but also plain text if it's been escaped), subtext (the text to replace found text with. Note $1,$2... for replacing groups in regtext), and the text itself.

Many thanks Mark,

 I will return to you with my evaluation result.

Cheers

Hi Mark,

 It works great! Some question:

The macro has three parameters

• text
• subtext
• regtext

Is it possible to send a whole tiddler to macro, e.g text=<<currentTiddler>> ?

does regtext accept the same JS regexp expression?

--Mohammad

[Mohammad]

If I can send rexexp pattern, then can I extract few character of some words or phrases?

Do it as a macrocall:

<$macrocall $name="regexpsub" regtext="Hello" subtext="Goodbye" text={{HelloThere}}/>

Got it!

[@TiddlyTweeter]

Though I don't grasp the mechanics I can see this is exciting !

[Mohammad]

Hi Josiah,

 I am experimenting to see how Commander can search in tiddlers meet some criteria and makes search/replace subtexts!

Also for tiddler partial renaming, for example change  the word `exmp` with a word `sample`in title of a set of tiddlers all have in their title the word exmp.

This is now partially works in TW-Commander,
