This project provides utilities to help generating pretty ebook files in various formats directly from arbitrary source trees. Generate static HTML sites from source trees -------------------------------------------- Before you begin, ensure you have installed all the [prerequisites](https://github.com/agentzh/code2ebook/blob/master/#prerequisites) (well, don't be scared, just `vim`, `ctags`, and `perl` ;)). ### src2html.pl The `src2html.pl` script can generate an HTML tree from the source tree that you specify, for example: ```bash export PATH=/path/to/code2ebook:$PATH cd /path/to/your/project/ src2html.pl --tab-width 4 --color --cross-reference \ --navigator --line-numbers . 'Your Book Title' ``` The resulting HTML site can be viewed in a web browser. And the entry point is `html_out/index.html` (according to the command above). The default output directory is `./html_out/`, and you can change that by specifying the `--out-dir=DIR` option (or `-o DIR` for short). The following image shows what a typical HTML page looks like when rendered by a web browser:  See [Sample eBooks](https://github.com/agentzh/code2ebook/blob/master/#sample-ebooks) for more complicated real-world sample outputs. Note that, for ebook readers lacking colors (like Amazon Kindle), then you should not specify the `--color` option for the `src2html.pl` script. The output is essentially an HTML-formatted "ebook", which is readily browsable in a web browser on either a PC or a tablet. [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) #### Change CSS style It is worth mentioning that if you do not like the default colors or have further style requirements, you can just specify the `--css FILE` option to make the HTML pages use your own CSS file. You can start with the default CSS file (named `default.css`) in this project. [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) #### Usage For the full usage of this script, specify the `-h` or `--help` options. One sample output is ``` src2html.pl [options] dir book-title Options: --charset CHARSET Specify the charset used by the HTML outputs. Default to UTF-8. -c --color Use full colors in the HTMTL outputs. --css FILE Use FILE as the CSS file to render the HTML pages instead of using the default style. -e PATTERN --exclude PATTERN Specify a pattern for the source code files to be excluded. -h --help Print this help. -i PATTERN --include PATTERN Specify the pattern for extra source code file names to include in the HTML output. Wildcards like * and [] are supported. And multiple occurrences of this option are allowed. --include-only PATTERN Specify the files to be processed and all other files are excluded. This option takes higher priority than "--include PATTERN". -j N --jobs N Specify the number of jobs to execute simultaneously. Default to 1. CPAN module Parallel::ForkManager is required when the number is bigger than 1. -l --line-numbers Display source code line numbers in the HTML output. -n --navigator Generate a navigator bar containing the "Top Level" and "One Level Up" links in the HTML output pages. -o DIR --out-dir DIR Specify DIR as the target directory holding the HTML output. Default to "./html_out". -t N --tab-width N Specify the tab width (number of spaces) in the source code. Default to 8. -x --cross-reference Turn on cross referencing links in the HTML output.

Just a quick reminder, CPAN module [Parallel::ForkManager](https://github.com/agentzh/code2ebook/blob/master/https://metacpan.org/pod/Parallel::ForkManager) is required when the number `N` is bigger than 1. The following example shows that it takes more than 30 minutes with `-j 1` to generate an HTML tree from the [ngx_openresty-1.9.3.2] (https://openresty.org/download/ngx_openresty-1.9.3.2.tar.gz) code base. While it takes less than 3 minutes with `-j 18` to generate the same HTML tree on my 24-core processor. ```console $ time src2html.pl --navigator --color --cross-reference --line-numbers \ -j 1 ngx_openresty-1.9.3.2/bundle openresty-1.9.3.2 ... real 30m43.686s user 30m26.818s sys 0m15.420s $ time src2html.pl --navigator --color --cross-reference --line-numbers \ -j 18 ngx_openresty-1.9.3.2/bundle openresty-1.9.3.2 ... real 2m49.172s user 35m56.337s sys 0m28.412s ``` [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) #### HTML output features This `src2html.pl` script generates pretty HTML pages for each source code file featuring [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) 1. Summarized data types, macros, global variables, and functions defined in each source code file shown as TOC at the beginning of the corresponding HTML page. 2. Colorful syntax highlighting via the `vim` program (enabled by the `--color` option, or `-c` for short). 3. Cross-reference links to the definition lines of the referenced data types, macros, global variables, and functions across all the source code lines (similar to the [LXR Cross Referencer](https://github.com/agentzh/code2ebook/blob/master/http://sourceforge.net/projects/lxr/) but ours is much more lightweight). This is enabled by the `--cross-reference` option (or the `-x` option for short). [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) #### Source file types recognized Right now all the file extension names known to your `ctags` program are supported. But `.html` and `.htm` files are always excluded to avoid infinite recursion. For the full language list supported by this tool, just type the following command: ```bash ctags --list-maps=all ``` You can explicitly include extra source files by specifying as many `--include=PATTERN` options as you like, as in ```bash src2html.pl --include='src/*.blah' --include='*foo*' . "my project" ``` Similarly, you can also exclude files by specifying one or more `--exclude=PATTERN` options. [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) Convert the HTML site to ebooks in various formats -------------------------------------------------- Now that we have the HTML-formatted "ebook", we can generate ebooks in other formats like `.mobi` and `.epub` using [Calibre](https://github.com/agentzh/code2ebook/blob/master/http://calibre-ebook.com/). [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) ### Generate MOBI ebooks for Kindle For example, to generate a `.mobi` file for Kindle DX: ```bash cd /path/to/your/project/ # assuming we specified the "." directory while running src2html.pl ebook-convert html_out/index.html my-project.mobi \ --output-profile kindle_dx --no-inline-toc \ --title "Your Book Title" --publisher 'Your Name' \ --language en --authors 'Your Author Name' ``` In this example, the resulting ebook file is named `my-project.mobi` in the current working directory. Note: On OS X you have to go to `Preferences->Advanced->Miscellaneous` and click `install command line tools` to make the command line tools available after you installed the app. On other platforms, just start a terminal and type the command. Here we use the value "kindle_dx" for the `--output-profile` option assuming that we want to view the ebook in Kindle DX. You should use "kindle" for other (smaller) models of Kindle. The ebook-convert utility is provided by Calibre, see its online documentation for full usage: https://manual.calibre-ebook.com/generated/en/ebook-convert.html Well you need both Perl and Python ;) [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) ### Generate EPUB ebooks for iPad/iPhone Below is a simple sample command to generate the `.epub` ebook from the HTML site: ```bash cd /path/to/your/project/ # assuming we specified the "." directory while running src2html.pl ebook-convert html_out/index.html my-project.epub \ --output-profile ipad3 \ --no-default-epub-cover \ --title "Your Book Title" --publisher 'Your Name' \ --language en --authors 'Your Author Name' ``` In this example, the resulting ebook file is named `my-project.epub` in the current working directory, which is readily readable in apps like `iBooks` on iPad or iPhone. [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) ### Generate PDF ebooks for Sony Digital Paper For example, to generate a `.pdf` file for Sony Digital Paper: ```bash cd /path/to/your/project/ # assuming we specified the "." directory while running src2html.pl ebook-convert html_out/index.html my-project.pdf \ --override-profile-size \ --paper-size a4 \ --pdf-default-font-size 12 \ --pdf-mono-font-size 12 \ --margin-left 10 --margin-right 10 \ --margin-top 10 --margin-bottom 10 \ --page-breaks-before='/' ``` In this example, the resulting ebook file is named `my-project.pdf` in the current working directory, which is readily readable in Sony Digital Paper or other e-reader devices supporting PDF ebooks (but you may need to adjust the `--paper-size a4` option if your device screen is too small for A4 pages). [Back to TOC](https://github.com/agentzh/code2ebook/blob/master/#table-of-contents) Prerequisites ============= You need to install the following dependencies of a recent version (the newer, the better): * [Exuberant ctags](https://github.com/agentzh/code2ebook/blob/master/http://ctags.sourceforge.net/) should be readily available in almost all the Linux distributions by simply installing the `ctags` package. * [vim](https://github.com/agentzh/code2ebook/blob/master/http://www.vim.org/) should be readily available in almost all the Linux distributions by simply installing the `vim` package. * [perl](https://github.com/agentzh/code2ebook/blob/master/http://www.perl.org/) should be readily available in almost all the Linux distributions by simply installing the `perl` package. It is worth mentioning that perl 5.10 or above is highly recommended due to performance boost in the perl regex engine. But older versions of perl should also work as well, just much slower (like 30x slower). All these components are very common programs in the \*NIX world.
