followme - Simple static website creation and maintenance
followme [file or directory]
Update a static website after changes. Constant portions of each page are updated to match, text files are converted to html, and indexes are created for new files in the archive.
The script is run on the directory or file passed as its argument. If no argument is given, it is run on the current directory.
If a file is passed, the script is run on the directory the file is in. In addition, the script is run in quick mode, meaning that only the directory the file is in is checked for changes. Otherwise not only that directory, but all directories below it are checked.
First, create a folder to contain the new website. Run followme with the init option in that directory
mkdir website cd website followme --init
It will install the initial templates and configuration files. The initial setup is configured to update pages to maintain a consistant look for the site and to create a weblog from files placed in the archive directory. If you do not want a weblog, just delete the arcive directory and its contents.
To start creating your site, create the index page as a text file, run followme again, and edit the resulting page:
vi index.txt followme vi index.html
The first page will serve as a prototype for the rest of your site. When you look at the html page, you will see that it contains comments looking like
<!-- section content --> <!-- endsection content -->
These comments mark the parts of the prototype that will change from page to page from the parts that are constant across the entire site. Everything outside the comments is the constant portion of the prototype. When you have more than one html page in the folder, you can edit any page, run followme, and the other pages will be updated to match it.
So you should edit your first page and add any other files you need to create the look of your site.
You can also use followme on an existing site. Run the command
in the top directory of your site. The init option will not overwrite any existing files in your site. Then look at the page template it has created:
Edit the existing pages in your site to heve all the section comments in this template.
The configuration file for followme is followme.cfg in thr top directory of your site. It contains the names of the Perl modlues that are run when the followme command is run:
module = App::Followme::FormatPages module = App::Followme::ConvertPages
FormatPages runs the code that keeps the pages consistent with the prototype. ConvertPages changes text files to html pages using a template and the prototype. The modules are run in the order that they appear in the, configuration file. If you want to change or add to the behavior of followme, write another module and add it to the file. Other lines in the configuration file modify the default behavior of the modules by over ridding their default parameter values. For more information on these parameters, see the documentation for each of the modules.
ConvertPages changes text files into html files. It builds several variables and substitutes them into the page template. The most significant variable is body, which is the text contained in the text file, modified by adding paragraph tags around all paragraphs that are not already surrounded by html tags. Other variables are the the title, which is built from the file name, replacing dashes with blanks and capitalizing each word, and the url, which is built from the html file name. A number of time variables are built from the modification date of the text file: weekday, month, monthnum, day, year, hour24, hour, ampm, minute, and second. To change the look of the html page, edit the template. Only blocks inside the section comments will be in the resulting page, editing the text outside it will have no effect on the resulting page.
A larger website will be spread acrss several folders. Each folder can have its own configuration file. If they contain modules, they will be run on that folder and all the subfolders below it. After initialization, the website is configured with an archive folder containing a configuration file. This file contains to modules that implement a weblog:
module = App::Followme::CreateNews module = App::Followme::CreateIndexes
CreateNews generates an html file from the most recently updated files in the archive directory. CreateIndexes builds an index file for each directory with links for all the subdirectories and html contained in it. Templates are used to build the html files, just as with individual pages, and the same variables are available. The template to build the html for each file in the index is contained between
<!-- loop --> <!--endloop -->
In addition to normal section blocks, there are per folder section blocks. The contents of these blocks is kept constant across all files in a folder and all subfolders of it. If the block is changed in one file in the folder, it will be updated in all the other files. Per folder section blocks look like
<!-- section in folder_name --> <!-- endsection -->
where folder_name is the the folder the content is kept constant across. The folder name is not a full path, it is the last folder in the path.
Followme is run from the folder it is invoked from if it is called with no arguments, or if it is run with arguments, it will run on the folder passed as an argument or the folder the file passed as an argument is contained in. Followme looks for its configuration files in all the directories above the directory it is run from and runs all the modules it finds in them. But they are are only run on the folder it is run from and subfolders of it. Followme only looks at the folder it is run from to determine if other files in the folder need to be updated. So after changing a file, it should be run from the directory containing the file.
