Atext2html

Atext2html is a command line utility written with Nom to recognize hyperlinks and link reference definitions in Markdown, reStructuredText, Asciidoc and HTML formatted text input. Atext2html renders the source text verbatim to HTML, but makes hyperlinks clickable. By default the hyperlink's text appears the same as in the source text. When the flag --render-links is given, hyperlinks are represented only by their link text, which makes inline links more readable.

Atext2html illustrates the usage of the underlaying library Parse-hyperlinks. The API of Parse-hyperlinks provides insights about the operating principle of this utility.

Installation:

bash cargo install atext2html

Usage examples

Markdown

1. Create a file input.txt with text and hyperlinks:

   md abc[text10](destination10 "title10")abc abc[text11][label11]abc abc[text12](destination2 "title12") abc[text13]abc

2. Run atext2html:

   shell $ ./atext2html -o output.html input.txt

3. Inspect output.html:

   ```html

   abc[text10](destination10 "title10")abc
   abc[text11][label11]abc
   abc[text12](destination2 "title12")
   abc[text13]abc

   ``` This is how it looks like in the web browser: ```shell $ firefox output.html ```

   abc[text10](destination10 "title10")abc
   abc[text11][label11]abc
   abc[text12](destination2 "title12")
   abc[text13]abc
   

reStructuredText

1. Create a file input.txt with text and hyperlinks:

   rst abc `text21 <label21_>`_abc abc text22_ abc abc text23__ abc abc text_label24_ abc abc text25__ abc .. _label21: destination21 .. _text22: destination22 .. __: destination23 __ destination25

2. Run atext2html:

   shell $ ./atext2html -o output.html input.txt

3. Inspect output.html:

   ```html

   abc `text21 <label21_>`_abc
   abc text22_ abc
   abc text23__ abc
   abc text_label24_ abc
   abc text25__ abc
   .. _label21: destination21
   .. _text22: destination22
   .. __: destination23
   __ destination25

   ``` This is how it looks like in the web browser: ```shell $ firefox output.html ```

   abc `text21 <label21_>`_abc
   abc text22_ abc
   abc text23__ abc
   abc text_label24_ abc
   abc text25__ abc
   .. _label21: destination21
   .. _text22: destination22
   .. __: destination23
   __ destination25
   

Asciidoc

1. Create a file input.txt with text and hyperlinks:

   adoc abc abc https://destination30[text30]abc abc link:https://destination31[text31]abc abc{label32}[text32]abc abc{label33}abc :label32: https://destination32 :label33: https://destination33

2. Run atext2html:

   shell $ ./atext2html -o output.html input.txt

3. Inspect output.html:

   ```html

   abc
   abc https://destination30[text30]abc
   abc link:https://destination31[text31]abc
   abc{label32}[text32]abc
   abc{label33}abc
   :label32: https://destination32
   :label33: https://destination33

   ``` This is how it looks like in the web-browser: ```shell $ firefox output.html ```

   abc
   abc https://destination30[text30]abc
   abc link:https://destination31[text31]abc
   abc{label32}[text32]abc
   abc{label33}abc
   :label32: https://destination32
   :label33: https://destination33
   

HTML

1. Create a file input.txt with text and hyperlinks:

   adoc $ ./atext2html -o output.html input.txt

2. Run atext2html:

   shell $ ./atext2html <input.txt >output.html $ ./atext2html <input.txt >output.html

3. Inspect output.html:

   ```html

   abc<a href="dest1" title="title1">text1</a>abc
   abc<a href="dest2" title="title2">text2</a>abc

   ``` This is how it looks like in the web-browser: ```shell $ firefox output.html ```

   abc<a href="dest1" title="title1">text1</a>abc
