Advanced configuration

❗️ This page works with URL rewriting enabled ❗️

By default, the same style is used for all the pages, //htmgem/css/htmgem.css//, except when a file having the same name as the page but with the extension **.css** exists in the same directory. In such as case, it's used.

When the CSS option is activated in the configuration (see /rewrite// below) other behaviors are possible. **Beware**, it won't work with a Gemini client as HtmGem is only reachable with a web browser.

&style=**htmgem** : Uses the default style.
&style=**none** : The page HTML is sent without style.
&style=**<autre nom>** : The file htmgem/css/<autre nom>.css is used as a style.
&style=**/<path>** : The provided file (absolute path) is used as a style.
&style=**source** : The source code of the page is sent to the browser, see below…
&style=**pre** : The source code of the page is sent to the browser enclosed in //<pre>//, see below…

URL rewriting to set the style to use

Modifying the web server configuration works but it's rather heavy. It's possible to test a particular style this way:

https://site.tld/htmgem/index.php?url=/url/page.gmi&style=<…>

It's also possible to make a URL rewriting which incorporate the style:

rewrite ^(.+\.gmi)$ /htmgem/index.php?rw=1&url=$1;

rewrite ^(.+\.gmi)\ *\|\ *([\w_]+)$ /htmgem/index.php?rw=1&url=$1&style=$2;

For instance, when it's activated:

Shows the readable source code on the screen, using the markup **<pre>**.

configuration-en.gmi | source : Downloads the source code.

With style already included…

Style //HtmGem//, the default style

Style selector: the page containing the style allows to test them 😎

Text decoration

The text decoration, which interprets the **bold** for instance, is not part of GemText definition. The text decoration applies everywhere except on the titles and preformated texts.

Disable the text decoration

It's possible to:

disable and enable the text decoration with a line **^^^**,
add what follows to the URL **rewriting**:

&textDecoration=0

BNF / Syntax

HtmGem uses a precise implementation of the GemText BNF. It indicates exactly what text portions are to be used.

How to build GemText pages?

———————————————————— ————————————————————

Amongst the distributed files and directories, only the ones below are useful for HtmGem:

**htmgem/*.php** : These files translate the GemText to HTML.
**htmgem/css/htmgem.css** : If it's missing, the display will be without style — literally.
**htmgem/css/…** : Keep the styles you use.

The others can be deleted (included this present file //configuration-en.gmi//) although they are not harmful.
