## File Format
**/etc/csvn-ui.rc** is a regular text file created by user to present Subversion repositories. This file
reads by [**cscnd(8)**](https://csvn.radix.pro/cscm/trunk/doc/cscmd.8.md) daemon and converts to binary
form for **cSvn-ui** CGI script. Binary format allows to minimize the time needed for complete HTTP
responses.
The configuration file consists of a set of variable or repository declarations also configuration
file can contains section of repository descriptions. The C/C++ comments are available:
```dts
/****************************
Apache's SVN repositories:
*/
home-page = "https://svn.apache.org/";
repo 'subversion' {
owner = "Apache";
description = "Source repository of the Subversion.";
checkout-prefix-readonly = 'https://svn.apache.org/repos/asf';
}
section "Other Repositories" {
repo 'other-repository' {
. . .
}
. . .
}
```
### Data Types
Configuration file assumes three types of variables.
> **int** – integer constants. Example declaration:

by following way:
```dts
description = "Subversion repositories"
" hosted at example.org "
"(St.-Petersburg)";
```
#### keywords
The **string** variable contains space separated keywords used in the HTML header of all **cSvn-ui**
pages as a page keywords. Default value: *"cSvn repositories"*. Example declaration:

```
#### home-page
The URL of the home page of the project. Default value: *"https://example.org"*.
Example declaration:
```dts
home-page = "https://main-site-of-the-project.org";
```
### Analytics variables:
#### analytic-links
The path to the file which contains meta tags with site ownership verificaton codes for engines such as *Google Search Console* or
*Yandex Webmaster*. **cSvn-ui** CGI Script reads the file **analytic-links** in RAW format and includes it into <HEAD> tag of each HTML page.
Example declaration:
```dts
analytic-links = '/analytics/links';
```
Where the file */analytics/links* may contains HTML tags like follow:
```html
```
The file name should be defined relative of the path where **cSvn-ui** CGI Script is installed. For example, if **cSvn-ui** CGI Script installed
into */srv/www/htdocs/csvn* directory and file name declared as */analytics/links* then **cSvn-ui** CGI Script will try to read the
file */srv/www/htdocs/csvn/analytics/links*.
#### analytic-scripts
The path to the file which contains *JavaScripts* for engines such as *Google Search Console* or
*Yandex Webmaster*. **cSvn-ui** CGI Script reads the file **analytic-scripts** in RAW format and includes it at the end of <HEAD> tag before
</HEAD> entry of each HTML page. Example declaration:
```dts
analytic-scripts = '/analytics/scripts';
```
Where the file */analytics/scripts* may contains code like follow:
```html
```
Please note that the *<script>* tags should be present in the */analytics/scripts* because **cSvn-ui** CGI Script reads this file
in RAW format and includes it as is.
The variables **analytic-links** and **analytic-scripts** should be declared on the global level of the **/etc/csvn-ui.rc**
configuration file and cannot be overriden in a repository declaration.
### Donation variables:
The **cSvn-ui** CGI Script provides the ability to create a custom donation dialogue. To do this, you need to create a set of three files:
**CSS**, **HTML**, and **JavaScript** file for automation. You can add a donation dialogue for each repository separately, as well as for the
entire list of repositories. To enable donation dialogue you have to set the value of **donate** variable to **donate = 1**:
#### donate
The integer variable used to enable or disable donation dialogue. Example declaration:
```dts
donate = 1;
```
#### donate-css
The name of file contains the stylesheet for donation modal dialogue. Example declaration:
```dts
donate-css = '/donations/donate.css';
```
#### donate-html
The name of file contains the HTML code of donation modal dialogue. Example declaration:
```dts
donate-html = '/donations/donate.html';
```
#### donate-js
The name of file contains the javascript code for donation modal dialogue automation. Example declaration:
```dts
donate-js = '/donations/donate.js';
```
**cSvn-ui** CGI Script includes these files at end of <BODY> tag just before the closing </BODY> tag. Unlike the others,
the **donate-html** file should be no more than 8192 bytes in size due to the fact that this file is a template
and the values of the following two variables are substituted into its body using placeholders *${donate-header}*
and *${donate-purpose}*:
#### donate-header
The title of the donation modal dialogue defined in the **donate-html** file. Example declaration:
```dts
donate-header = "Donations";
```
#### donate-purpose
The donation purpose used as value of <input value="..."> tag property in payment form of systems such as **PayPal** or **Yandex.Money**.
Also this value can be used as a header of modal dialogue content. Example declaration:
```dts
donate-purpose = "Support for our projects";
```
Donation dialogue can be defined for each repository separately or defined on global level. In the last case
the dialogue header and payment purpose may be overriden in the body of a repository declaration like follow:
```dts
true = 1;
false = 0;
donate = true;
donate-css = '/donations/donate.css';
donate-html = '/donations/donate.html';
donate-js = '/donations/donate.js';
donate-header = "Donation";
donate-purpose = "Support our activities";
section "Tools" {
repo 'repo-path' {
. . .
donate-header = "Project Donation";
donate-purpose = "Support our Project";
. . .
}
}
```
To show the modal dialogue in javascript code **donate-js** the selector **'a.donate'** should be used. For examle, like this:
```php
var show = document.querySelector( "a.donate" );
/**************
Open Dialog:
*/
show.onclick = function() {
dialog.style.display = "block";
}
```
Where the variable *dialog* points to modal dialogue defined in the **donate-html** file.
### Repository Declaration
The **/etc/csvn-ui.rc** config file should contains at least one repository declaration to be shown
by the **cSvn-ui** CGI Script. When all expected variables declared in the global section
the config file the repository declaration can be very simple:
```dts
repo 'tools' {
owner = "John Smith";
description = "John Smith's tools source code repository.";
}
```
The list of repositories can be splitted in several sections. The section has a name and can
contains repository declarations only.
```dts
section "John Smith sources" {
repo 'tools' {
owner = "John Smith";
description = "John Smith's tools source code repository.";
}
repo 'examples' {
owner = "John Smith";
description = "John Smith's examples source code.";
}
}
```
Please note, repositories, unlike sections, do not have a name, but have a **path** to repository.
So if your repositories in the file system are stored in the `/var/scm/svn` directory, and the
`tools` repository is located in the `/var/scm/svn/tools` directory, then the path to the repository
is set relative to the `/var/scm/svn` directory as follows:
```dts
repo 'tools' {
owner = "John Smith";
description = "John Smith's tools source code repository.";
}
```
## Working Example
As an example, we will give a working configuration file in which the **cSvn-ui** repository is presented.
```dts
svn-utc-offset = +0300;
checkout-prefix-readonly = 'svn://radix.pro';
checkout-prefix = 'svn+ssh://svn@radix.pro';
branches = 'branches';
trunk = 'trunk';
tags = 'tags';
snapshots = 'tar.xz';
css = '/.csvn/css/csvn.css';
logo = '/.csvn/pixmaps/csvn-banner-280x280.png';
logo-alt = "Radix.pro";
logo-link = "https://radix.pro";
main-menu-logo = '/.csvn/pixmaps/logo/SVN-logo-white-744x744.svg';
favicon-path = '/.csvn/pixmaps/favicon';
syntax-highlight-css = '_csvn.css';
header = '/.csvn/html/header.html';
footer = '/.csvn/html/footer.html';
page-size = 200;
owner = "Andrey V.Kosteltsev";
author = "Andrey V.Kosteltsev";
title = "Radix.pro SVN Repositories";
description = "Subversion repositories hosted at radix.pro (St.-Petersburg)";
keywords = "cSvn repositories";
copyright = "© Andrey V. Kosteltsev, 2019 – 2020.";
copyright-notice = "Where any material of this site is being reproduced, published or issued to others the reference to the source is obligatory.";
home-page = "https://radix.pro/";
section "Tools" {
repo 'csvn-ui' {
owner = "Andrey V.Kosteltsev";
title = "cSvn-ui for SVN Repositories";
description = "cSvn-ui – is a web interface for Subversion™ Repositories written in C";
home-page = "https://radix.pro/";
}
}
```
