40# inbtw
`inbtw` (a.k.a. "in between"), is a small utility to extract the text in between two tags.
```bash mdox-exec="inbtw" mdox-expect-exit-code=2
inbtw extracts the text between tags.
A tag is defined by "// [START " and "// [END "
Example for a file containing:
// [START mytag]
var Bla = "bla"
// [END mytag]
executing:
> inbtw -tag mytag -f myfile.go
will yield:
var Bla = "bla"
Usage of inbtw:
-f string
file(s) to parse, multiple files can be separated by ',', '-' for stdin.
-tag string
tag containing the text to extract.
```
## Purpose
To extract code snippets in order to render them in a document. It requires less maintenance than something like `sed` because it needs line numbers, and less complicated than regex or `awk`.
## Installing
```shell
go install github.com/veggiemonk/inbtw@latest
```
