need to replace TF to ThreeFold
need to replace ThreeFold0 to ThreeFold
need to replace ThreeFold1 to ThreeFold

'

text_out := '

this is TTT SomeTest
this is TTT SomeTest

need to replace ThreeFold to ThreeFold
need to replace ThreeFold to ThreeFold
need to replace ThreeFold to ThreeFold

'

mut ri := regext.regex_instructions_new()
ri.add(['TF:ThreeFold0:ThreeFold1:ThreeFold']) or { panic(err) }
ri.add_item('test_1', 'TTT') or { panic(err) }
ri.add_item('^Stest 1', 'TTT') or { panic(err) } //will be case insensitive search

mut text_out2 := ri.replace(text: text, dedent: true) or { panic(err) }

//pub struct ReplaceDirArgs {
//pub mut:
//	path       string
//	extensions []string
//	dryrun     bool
//}
// if dryrun is true then will not replace but just show
ri.replace_in_dir(path:"/tmp/mypath",extensions:["md"])!
