### Compiling

You need to have Go toolchain installed:
```shell
# Debian
sudo apt install golang

# Fedora
sudo dnf install golang
```

Then, just **clone the repo** and run **`go build .`** to compile an executable.

### Usage
```shell
gemtext2gophermap input.gmi output_gophermap [max line length (default 70)] [preprocessor insertion map file]
```

## Example

**input.gmi**
````markdown
Everything until the first <!--break--> in the map file will be put in place of the following insert-gopher tag.

<!--insert-gopher-->

The <script> tag should be removed because it is between two web-only tags.

<!--web-only-->
<script>
console.log("joj")
</script>
<!--web-only-->

> Everything after the first <!--break--> in the map file:

<!--insert-gopher-->
````

**map.txt**
```gophermap
<?php
echo "i" . date(DATE_RFC2822) . "\tFAKE\tNULL\t0";
?>
<!--break-->
A line from map.txt
```

> If a line in map.txt isn't in format `i /PATH host 123` it **will not** automatically get converted into that format,
> your **server is expected to do that** or you should write that explicitly in the map.txt file.
> 
> This has been done to allow injecting PHP scripts.
> (to avoid: `i<?php /FAKE NULL 0`)

#### Command
```shell
gemtext2gophermap input.gmi - 70 map.txt
```
If `-` is passed instead of `input or output` file name `stdin or stdout` will be used. Reading the **map file from stdin** is **not supported**.

#### Output
```gophermap
iEverything until the first <!--break--> in the map file will be put in /FAKE   NULL    0
iplace of the following insert-gopher tag.      /FAKE   NULL    0
<?php
echo date(DATE_RFC2822);
?>

iThe <script> tag should be removed because it is between two web-only   /FAKE   NULL    0
itags.  /FAKE   NULL    0
i> Everything after the first <!--break--> in the map file:     /FAKE   NULL    0
