Description: # TestFlows-Texts
        TestFlows.com Open-Source Software Testing Framework Texts
        
        Use `testflows.texts` Python module to help you write auto verified software documentation
        by combining your text with the verification procedure of the described functionality
        in the same source file while leveraging the power and flexibility of [TestFlows.com Open-Source Test Framework](https://testflows.com).
        
        Source files for auto verified documentation by convention have `.tfd` extension
        and are written using Markdown. Therefore, all `.tfd` files are valid
        Markdown files. However, `.tfd` files are only the source files for your documentation
        that must be executed using `tfs document run` command to produce final 
        Markdown documentation files.
        
        ```bash
        $ tfs document run --input my_document.tfd --output my_document.md
        ```
        
        ## Requirements
        
        * Python3 >= 3.8
        
        ## Install
        
        You can install `testflows.texts` using `pip3` command:
        
        ```bash
        pip3 install --upgrade testflows.texts
        ```
        
        After installing `testflows.texts` you will also have `tfs` command available in your environment.
        
        ## Writing Auto Verified Docs
        
        Follow the example Markdown document to get to know how you can write auto verified docs yourself.
        
        ```markdown
            ## This is a heading
        
            This file is written using Markdown where you can have any number
            of `python:testflows` code blocks that contain executable Python code.
            
            ```python:testflows
            # This is Python code that will be executed when .tfd document is run.
            
            msg = "Hello TestFlows Texts"
            ```
         
            The scope is shared between all the code blocks in the same document.
            
            ```python:testflows
            # so `msg` variable define above can also be accessed in this
            # `python:testflows` code block
        
            new_msg = msg + " Thanks for making verifying docs so easy!"
            ```
            
            The output of executing `.tfd` document using `tfs document run`
            is the final `.md` file with all the `python:testflows` code blocks
            removed and replaced with the text added to the document using
            the `text()` function.
        
            ```python:testflows
            # Let's use `text()` function to add some text to our document
            # dynamically in our Python code
         
            text("add this line to the final Markdown document")
            ```
            
            Any text outside the `python:testflows` code blocks are treated as Python
            f-strings. This allows you to specify expressions for substitutions.
            See [Python formatted string literals](https://docs.python.org/3/tutorial/inputoutput.html#formatted-string-literals)
            for more details.
            
            Here is an example where we will substitute the value of `msg` variable next {msg}.
            But with Python f-strings you can specify even complex expressions. For example, we can 
            convert our string in `msg` to title case as follows {msg.title()}.
            
            You can double your curly braces to escape them when substitution expression is not needed
            using `{{` or `}}`.
            
            By the way, your document can't contain any triple double quotes `"""`. If you need them then you have to
            add them inside the `python:testflows` code block using `text()` function. For example,
            
            ```python:testflows
            text('"""')
            ```
            
            Well, this is pretty much it. With `testflows.texts` you have full power of full featured
            test framework and Python language at your disposal to make sure your documentation always
            stays to date.
        ```
        
        ## Using `tfs document run`
        
        ```bash
        $ tfs document run -h
        usage: tfs document run [-h] [-i path [path ...]] [-o [path]] [-f]

         ------------------
        
        Run executable document.
        
        Executable documents are Markdown documents that
        contain `python:testflows` code blocks which may contain
        any Python code that will be run during document execution.  
        
        All text within executable document except for the
        `python:testflows` code blocks are treated as Python f-strings.
        Therefore, you must escape any `{`, `}` characters by doubling
        them, for example: `{{` or `}}`, otherwise they will be treated
        as f-string expressions.
        
        Text must not contain triple quotes `"""`. If you need them
        then you must use `text()` function within `python:testflows` code block
        to explicitly add them to the the text. 
        
        For example:
            ```python:testflows
            text('adding triple quotes """ to text')
            ``` 
        
        Specify '--' at the end of the command line options to pass
        options to the executable document writer program itself.
        
        For example:
           tfs document run -i <path>--o <path> -- --help
        
        You must set PYTHONPATH when modules needed by the executable
        document are not in the default path.
        
        For example:
           PYTHONPATH=<path/to/module> tfs document run -i <path> -o <path>
        
        The `--input` can take multiple files and in such case if `--output`
        is specified it is treated as directory name.
        
        For example,
           tfs document run -i `find $(pwd) -name "*.tfd"` -o . -f 
        or
           tfs document run -i `find $(pwd) -name "*.tfd"` -o /path/to/output/dir -f 
        
        If input is '-' (stdin) and output is '.' then output file is 'document.md'
        which is created in the current working directory.
        
        optional arguments:
          -h, --help                                   show this help message and exit
          -i path [path ...], --input path [path ...]  input file, use '-' for stdin, default: stdin
          -o [path], --output [path]                   output file or directory if multiple input files are
                                                       passed, default: '.' or if input is stdin then '-'.
                                                       The '.' means to create output file in the same
                                                       directory as the input file having .md extension and
                                                       the '-' means output to stdout.
          -f, --force                                  force to override existing output file if it already
                                                       exists
