## Installation
First, clone this repository. Then change into the source directory and build the project.
```bash
git clone https://gitlab.schukai.com/oss/bob.git
cd bob/source
go build
```
### Nix/Flake Support
This repository contains a file called flake.nix. You can install this program
using the [nix package manager](https://nixos.org/).
```bash
nix build
```
## Usage
### Template
#### Prepare
```bash
bob template prepare \
--input ./templates/ \
--output ./output/ \
--data-file ./data.yaml \
```
This will create files in the `./output/` directory with all parsed templates from `./templates/` directory.
Also, a data YAML. This data YAML is used to generate the final files with the `bob html generate` command.
This command prepares the title, description, keywords, and other metadata for the templates.
Furthermore, it will parse the templates for images, anchors, and text.
If the argument `--data-file` is not set, the data YAML will be written to `./output/data.yaml`.
| Original | Parsed |
| ----------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- |
| `<html lang="en"><head>` | `<html lang="en" data-attributes="lang path:lang"><head>` |
| `<title>Bob</title>` | `<title data-attributes="title path:title">Bob</title>` |
| `<meta name="description" content="Bob is a html and html fragment builder">` | `<meta name="description" content="Bob is a html and html fragment builder" data-attributes="description path:meta.description">` |
| `<img alt="alt text" title="my title" src="..." ` | `<img alt="alt text" title="my title" src="..." data-attributes="alt path:img.id1003.alt title path:img.id1003.title src path:img.id1003.src">` |
| `<a href="https://gitlab.schukai.com/oss/bob">` | `<a href="https://gitlab.schukai.com/oss/bob" data-attributes="href path:a.id1004.href">` |
| `<p>Bob is a html and html fragment builder</p>` | `<p><span data-attributes="text path:p.id1005.text">Bob is a html and html fragment builder</span></p>` |
If you want to translate the text, you can copy the default `data.yaml` to a new file and translate the text there.
A good practice is to use the language code as the file name.
For example, `de.yaml` for German, `en.yaml` for English, etc.
Beside text, images and metadata, special attributes are also extracted.
For example, the Monster datatable headers `data-monster-head` are extracted.
```html
<monster-datatable>
<template id="datatable-order-list-row">
<div data-monster-head="OID" ...></a></div>
...
```
If you want to add Javascript translations, a consecutive ID is assigned if not
specified separately. This is not ideal for several reasons. It is better to assign
your own ID. To be independent of HTML, JavaScript and CSS selectors, there is a
separate attribute `data-bob-reference` for this.
```html
<script type="application/json"
data-monster-role="translations"
data-bob-reference="my-translation">
{
"key1": "value1",
"key2": "value2",
"key3": {
"one": "value3",
"two": "value4"
}
}
```
#### HTML
##### Generate
This will generate HTML files from the prepared templates and data YAML.
The YAML must be located in the input directory. Any file with `.yaml` extension
will be processed.
```bash
bob html generate --input ./input/ --output ./output/ --data-files ./pages/
```
If the `--data-files' attribute is not defined, the `--input' directory is used.
The yaml looks like:
```yaml
test1.html:
export: en/test1.html
lang: en
title: TEST
meta:

```
The translations are set in a json inside a script tag.
The `modifications' rules are executed last. Here you can remove tags, add content and set attributes.
##### Sync
This will sync HTML nodes from a source to a destination.
```bash
bob html sync --specification ./specification.yaml
```
The structure of the specification file is as follows:
```yaml
sync:
- source:
path: "./source.html"
selector: "head"
destination:
path: "./"
exclude:
- ./source.html
keep:
- title
```
With the above specification, the `head` node from `./source.html` will
be synced to all files in `./` except `./source.html`.
Furthermore, the `title` node will be kept.
Relative paths are relative to the specification file. Absolute paths are absolute, obviously.
#### Cut
This will cut a node from a source file and save it to a destination template file.
```bash
bob template cut --specification ./specification.yaml
```
The structure of the specification file is as follows:
```yaml
snippet:
- source: ./test.html
selector: "head"
destination: ./snippets/container.html
attribute:
- selector: "li"
name: "class"
value: "list-item"
replacement:
- selector: "#myid"
content: "replacement content"
```
Relative paths are relative to the specification file.
## Contributing
The bob command line tool is written in Go. The environment is defined in the
`flake.nix` file.
If you want to build the project, you can use the `nix build` or use the task build.
```bash
task build
```
To update the version and get the vendor hash,
the task `task update-code` must be called.
The hash is currently always null, as a vendor directory is used
in the project. This is created with `go mod vendor`.
