Description: # Qualitative Coding
        
        Qualitative coding for comptuer scientists. 
        
        Qualitative coding is a form of feature extraction in which text (or images,
        video, etc.) is tagged with features of interest. Sometimes the codebook is
        defined ahead of time, other times it emerges through multiple rounds of coding.
        For more on how and why to use qualitative coding, see Emerson, Fretz, and
        Shaw's *Writing Ethnographic Fieldnotes* or Shaffer's *Quantitative
        Ethnography*.
        
        Most of the tools available for qualitative coding and subsequent analysis were
        designed for non-programmers. They are GUI-based, proprietary, and don't expose 
        the data in well-structured ways. Concepts from computer science, such as trees,
        sorting, and filtering, could also be applied to qualitative coding analysis if
        the interface supported it. 
        
        Qualitative Coding, or `qc`, was designed to address these issues. I have used
        `qc` as a primary coding tool in a [SIGCSE
        paper](http://chrisproctor.net/publications/proctor_2019_defining_cs.html) on
        how K-12 schools define and design computer science courses. The impetus for
        packaging and releasing a stable version was my own dissertation work. 
        
        ## Limitations
        
        - Due to its nature as a command-line program, `qc` is only well-suited to coding textual data. 
        - `qc` uses line numbers as a fundamental unit. Therefore, it requires text files in your corpus to be 
          hard-wrapped at 80 characters. The `init` task will handle this for you. 
        - Currently, the only interface for actually doing the coding is a split-screen
          in vim, with the corpus text on one side and comma-separated codes adjacent. This works well 
          for me, but might not work well for you. I have other ideas in the pipeline,
          but they won't be around soon.
        
        # Installation
        
            pip install qualitative-coding
        
        # Setup 
        
        - All the source files you want to code should be in a directory (possibly
          nested). 
        - Choose a working directory. Run `qc init`. This will create `settings.yaml`.
        - In `settings.yaml`, update `corpus_dir` with the directory holding your source
          files. This may be relative to `settings.yaml` or absolute. Similarly, specify
          directories for `codes_dir` `logs_dir`, `memos_dir`, and the YAML file where you want
          to store your codebook. Unless you're particular, the default settings are fine. 
        - Run `qc init --prepare-corpus --prepare-codes --coder yourname`. This will
          hard-wrap all the text in your corpus at 80 characters and create blank coding
          files. 
        
        # Usage
        
        ## Workflow
        
        `qc` is designed to give you a powerful terminal-based interface. The general
        workflow is to use `code` to apply qualitative codes to your text files. As you
        go, you will start to have ideas about the meanings and organization of your
        codes. Use `memo` to capture these. 
        
        Once you finish a round of coding, it's time to reorganize your codes. Use
        `codebook` to refresh the codebook based on new coding. Use `stats` to see the
        distribution of your codes. If you want to move codes into a tree, make these
        changes directly in the codebook's YAML. If you realize you have redundant
        codes, use `rename`. 
        
        The `--coder` argument supports keeping track of multiple coders on a project,
        and there are options to filter on coder where relevant. Analytical tools, such
        as correlations (on multiple units of analysis) and inter-rater reliability are
        coming. 
        
        ## Tutorial
        
        Create a new directory somewhere. We will create a virtual environment, intstall
        `qc`, and download some sample text from Wikipedia. 
        
            $ python3 -m venv env
            $ source env/bin/activate
            $ pip install qualitative-coding
            $ qc init
            $ qc init
            $ curl -o corpus/what_is_coding.txt "https://en.wikipedia.org/w/index.php?title=Coding_%28social_sciences%29&action=raw"
            $ qc init --prepare-corpus --prepare-codes --coder chris
        
        Why run `qc init` three times? The first time creates a prepopulated
        `settings.py` file. You could then change any settings. The second time 
        reads `settings.py` and creates the specified files and directories. 
        And the third run, with the flags, processes the corpus file and creates a
        corresponding coding file.
        
        Now we're ready to start coding. This next command will open a split-window vim session. 
        Add comma-separated codes to the blank file on the right. I usually page-up (control+u) 
        and page-down (control+d) each file to keep their line numbers synchronized. Once you've 
        added some codes, we can analyze and refine them.
        
            $ qc code chris -f
            $ qc codebook
            $ qc list
            - a_priori
            - analysis
            - coding_process
            - computers
            - errors
            - grounded_coding
            - themes
        
        Now that we have coded our corpus (consisting of a single document), we should
        think about whether these codes have any structure. All data in `qc` is stored
        in flat files, so you can easily modify it by hand. Re-organize some of your
        codes in `codebook.yaml`. When you finish, run `codebook` again. It will go
        through your corpus and add any missing codes. 
        
            $ qc list
            - analysis
            - coding_process
                - a_priori
                - grounded_coding
            - computers
            - errors
            - themes
        
        I decided to group a priori coding and grounded coding together under coding
        process. Let's see some statistics on the codes:
        
            $ qc stats
            Code                  Count
            ------------------  -------
            analysis                  2
            coding_process            7
            .  a_priori               2
            .  grounded_coding        2
            computers                 2
            errors                    1
            themes                    2
        
        `stats` has lots of useful filtering and formatting options. For example, `qc
        stats --files wiki --depth 1 --min 10 --format latex` would only consider files
        having "wiki" in the filename. Within these files, it would show only
        top-level categories of codes having at least ten instances, and would output a
        table suitable for inclusion in a LaTeX document. Use `--help` on any command to
        see available options.
        
        Next, we might want to see examples of what we have coded. 
        
            $ qc code analysis

            In the [[social science|social sciences]], '''coding''' is an analytical process | analysis

        Again, there are lots of options for filtering and viewing your coding. At some
        point, you will probably want to revise your codes. You can easily rename a
        code, or collapse codes together, with the `remane` command. This updates your 
        codebook as well as in all your code files.
        
            $ qc rename grounded_coding grounded
        
        At this point, you are starting to realize some of the deeper themes running
        through your corpus. Capturing these in an "integrative memo" is an important
        part of qualitative coding. `memo` will open a preformatted document for you in vim. 
        
            $ qc memo chris --message "Thoughts on coding process"
        
        Congratulations! You have finished the first round of coding. Before you move
        on, this would be an excellent time to check your files into version control.
        I hope you find `qc` to be powerful and efficient; it's worked for me!

        ## Commands
        
        Use `--help` for a full list of available options for each command.
        
        ### init
        Initializes a new coding project, as described above.
        
            $ qc init
        
        ### check
        Checks that all required files and directories are in place. 
        
            $ qc check
        
        ### code
        Opens a split-screen vim window with a corpus file and the corresponding code
        file. The name of the coder is a required positional argument. 
        Use `--pattern` to glob-match the corpus file you want to code. If
        multiple are matched, you will be prompted to choose. The `--first-without-codes` option is
        particularly useful for coding the next uncoded text.
        
            $ qc code chris -f
        
        ### codebook (cb)
        Scans through all the code files and adds new codes to the codebook. 
        
            $ qc codebook
        
        ### list (ls)
        Lists all the codes currently in use. By default, lists them as a tree. The `--expanded` option 
        will instead flatten the list of codes, and list each as something like `subjects:math:algebra`.
        
            $ qc list --expanded
        
        ### rename
        Goes through all the code files and replaces one code with another. Removes the old code from the codebook.
        
            $ qc rename funy funny
        
        ### find
        Displays all occurences of the provided code(s). With the `--recursive` option, also includes child
        codes in the codebook's tree of codes. Note that a code may appear multiple times in the codebook; in this case, 
        the `--recursive` option will search for all children of all instances. When you want to grab text for a quotation,
        use the `--textonly` option. The `--files` option lets you filter which corpus files to search.
        
            $ qc find math science art --recursive
        
        ### stats
        Displays frequency of usage for each code. Note that counts include all usages of children.
        List code names to show only certain codes. Filter code results with 
        `--depth`, `--max`, and `--min`. Use the `--expanded` option to show the full name of each code, rather than the 
        tree representation. Arguments to `--format` may be any supported by [tabulate](https://bitbucket.org/astanin/python-tabulate).
        The `--files` option lets you filter which corpus files to use in computing stats.
        
            $ qc stats curriculum math algebra --depth 1
