├── README.md └── bb.sh /README.md: -------------------------------------------------------------------------------- 1 | bashblog-ng 2 | ======== 3 | 4 | This is the Next Generation version of (https://github.com/cfenollosa/bashblog). Me, and [lots of other people](https://www.google.com/search?q=%22Generated+with+bashblog,+a+single+bash+script+to+easily+create+blogs+like+this+one%22), love bashblog as a simple tool to maintain a blog. The reason for bashblog-ng is simply that I wanted more features added but did not want to pollute the original bashblog with lots of pull requests. 5 | 6 | A single Bash script to create blogs. 7 | 8 | Created because someone wanted a very, very simple way to post entries to a blog by using a public folder on a server, without any special requirements and dependencies. Works on GNU/Linux, OSX and BSD. 9 | 10 | You can see a sample here: (https://yagni.rocks). That page was 100% generated using bashblog-ng, no additional tweaking. 11 | 12 | Check out [other bashblog-ng users](https://www.google.com/search?q=%22Generated+with+bashblog-ng+-+%28B%29e+%28A%29wesome+%26+%28S%29imple+%28H%29omie%22) 13 | 14 | 15 | Usage 16 | ----- 17 | 18 | Download the code and copy bb.sh into a public folder (for example, `$HOME/public_html/blog`) and run 19 | 20 | ./bb.sh 21 | 22 | This will show the available commands. If the file is not executable, type `chmod +x bb.sh` and retry. 23 | 24 | **Before creating your first post, you may want to configure the blog settings (title, author, etc). 25 | Read the Configuration section below for more information** 26 | 27 | To create your first post, just run: 28 | 29 | ./bb.sh post 30 | 31 | It will try to use Markdown, if installed. To force HTML: 32 | 33 | ./bb.sh post -html 34 | 35 | The script will handle the rest. 36 | 37 | When you're done, access the public URL for that folder (e.g. `http://server.com/~username/blog`) 38 | and you should see the index file and a new page for that post! 39 | 40 | 41 | Features 42 | -------- 43 | 44 | - Ultra simple usage: Just type a post with your favorite editor and the script does the rest. No templating. 45 | - No installation required. Download `bb.sh` and start blogging. 46 | - Zero dependencies. It runs just on base utils (`date`, `basename`, `grep`, `sed`, `head`, etc) 47 | - GNU/Linux, BSD and OSX compatible out of the box, no need for GNU `coreutils` on a Mac. 48 | It does some magic to autodetect which command switches it needs to run depending on your system. 49 | - All content is static. You only need shell access to a machine with a public web folder. 50 | *Tip: advanced users could mount a remote public folder via `ftpfs` and run this script locally* 51 | - Allows drafts, includes a simple but clean stylesheet, generates the RSS file automatically. 52 | - Support for tags/categories 53 | - Support for Markdown, Disqus comments, Twitter, Feedburner, Google Analytics. 54 | - The project is still maintained as of 2016. Bugs are fixed, and new features are considered (see "Contributing") 55 | - Everything stored in a single ~1k lines bash script, how cool is that?! ;) 56 | 57 | 58 | Configuration 59 | ------------- 60 | 61 | Configuration is not required for a test drive, but if you plan on running your blog with bashblog, you will 62 | want to change the default titles, author names, etc, to match your own. 63 | 64 | There are two ways to configure the blog strings: 65 | 66 | - Edit `bb.sh` and modify the variables in the `global_variables()` function 67 | - Create a `.config` file with your configuration values -- useful if you don't want to touch the script and be able to update it regularly with git 68 | 69 | The software will load the values in the script first, then overwrite them with the values in the `.config` file. 70 | This means that you don't need to define all variables in the config file, only those which you need to override 71 | from the defaults. 72 | 73 | The format of the `.config` file is just one `variablename="value"` per line, just like in the `global_variables()` 74 | function. **Please remember:** quote the values, do not declare a variable with the dollar sign, do not use 75 | spaces around the equal sign. 76 | 77 | bashblog uses the `$EDITOR` environment value to open the text editor. 78 | 79 | 80 | Detailed features 81 | ----------------- 82 | 83 | - HTML5 compatable 84 | - Support for github username with corner-link 85 | - A simple but nice and readable design, with nothing but the blog posts 86 | - **NEW on 2.0** Markdown support via a third-party library. 87 | The easiest method is to download 88 | Gruber's [Markdown.pl](http://daringfireball.net/projects/markdown/) 89 | - Post preview 90 | - Save posts as drafts and resume editing later 91 | - HTML page for each post, using its title as the URL 92 | - Configurable number of posts on the front page 93 | - Automatic generation of an RSS file, feedburner support 94 | - Additional page containing an index of all posts 95 | - Automatically generates pages for each tag 96 | - Rebuild all files while keeping the original data 97 | - Comments delegated to Twitter, with additional Disqus support 98 | - An option for cookieless Twitter sharing, to comply with the 99 | [EU cookie law](https://github.com/cfenollosa/eu-cookie-law) 100 | - Google Analytics code support 101 | - Contains its own CSS so that everything is reasonably styled by default 102 | - Headers, footers, and in general everything that a well-structured html file needs 103 | - Support to add extra content on top of every page (e.g. banners, images, etc) 104 | - xhtml validation, CSS validation, RSS validation by the w3c 105 | - Automatic backup of the site every time you post (stored as `.backup.tar.gz`) 106 | 107 | Read the Changelog section for more updates or [check out the news on my blog](http://cfenollosa.com/blog/tag_bashblog.html) 108 | 109 | 110 | Contributing 111 | ------------ 112 | 113 | Bashblog started at 500 SLOC and it now has hit the 1000 SLOC barrier. 114 | If we want to keep the code minimal and understandable, we need to make the difficult effort to restrain ourselves 115 | from adding too many features. 116 | 117 | All bugfixes are welcome, but brand new features need to be strongly justified to get into the main tree. 118 | Every new request will be honestly and civilly discussed on the comments. 119 | As a guideline, pull requests should: 120 | 121 | - Fix a use case for some people (e.g. internationalization) 122 | - Add a use case which is arguably very common (e.g. disqus integration for comments) 123 | - Be very small when possible (a couple lines of code) 124 | - Don't require a significant rewrite of the code (Don't break `create_html_file()` or `write_entry()`, etc) 125 | - It must work on Linux, BSD and Mac. Beware of using GNU coreutils with non-POSIX flags (i.e. `date` or `grep`) 126 | - Follow the UNIX philosophy: do one thing and do it well, rely on third party software for external features, etc 127 | - **Always** keep backwards compatibility when using the default configuration 128 | 129 | 130 | License 131 | ------- 132 | 133 | This program is free software: you can redistribute it and/or modify 134 | it under the terms of the GNU General Public License as published by 135 | the Free Software Foundation, either version 3 of the License, or 136 | (at your option) any later version. 137 | 138 | This program is distributed in the hope that it will be useful, 139 | but WITHOUT ANY WARRANTY; without even the implied warranty of 140 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
