## Templates
|
||||
|
||||
**This feature required `kotlin` to be installed in your system. [Read more](https://kotlinlang.org/docs/command-line.html#install-the-compiler)**
|
||||
|
||||
**You may run gradle task `generateKTStemplates` instead of raw launch, but it will work slowly. Sample `./gradlew generateKTStemplates`**
|
||||
|
||||
This project supports generating of files from `.ktstemplate.` files. Current docs:
|
||||
|
||||
### Using
|
||||
|
||||
* Create file contains `.ktstemplate` in its name
|
||||
* Write variables **before** the first `H*` (starting with `#`) section
|
||||
* Launch `kotlin ${thisscriptname}` with required args
|
||||
|
||||
#### File sample
|
||||
|
||||
```markdown
|
||||
first = hello
|
||||
second = world
|
||||
|
||||
# Sample
|
||||
|
||||
This is sample of $first $second
|
||||
```
|
||||
|
||||
Will have next result:
|
||||
|
||||
```markdown
|
||||
# Sample
|
||||
|
||||
This is sample of hello world
|
||||
```
|
||||
|
||||
### Launch
|
||||
|
||||
This script accept next args:
|
||||
|
||||
`[...paths] [--plain] [--recursive]`
|
||||
|
||||
Where:
|
||||
|
||||
* `...paths` - Paths to the files-templates or folders with files-templates
|
||||
* `--plain` - will look only into the folders from `paths`
|
||||
* `--recursive` - (default) will look into the folders from `paths` and recursively in subfolders
