I would suggest Recursive Descent for general parsing, and Precedence Climbing for expressions.

Once you get the hang of Recursive Descent, parsing becomes mechanical. And with Precedence Climbing for expressions, you just plug in the appropriate operator priorities.

Some of the literature below refers to "parsing" as "syntax analysis".

See this introductory set of articles:

https://www.semware.com/html/compiler.html

Then see this (small, 160 page) book from Wirth:

See examples here - especially the C and Python examples: (lexical analysis examples included, since it must feed the parser)

Thanks for the kind words. I was forced to change the name a few years back (1992) - it is now called TSE, or The Semware Editor.

Unlearn Wordstar key bindings? Isn't that sacrilege? :-)

I wrote one back in 1984-85 that I called QEdit, and have been using and updating it ever since.

Three that I've dabbled with are:

    - Euphoria   (http://openeuphoria.org/)
    - Wren       (http://wren.io/)
    - ChaiScript (http://chaiscript.com/)

Of those three, Euphoria is possibly the most widely used. It has also been around the longest - since 1993.

Back in 1984, I purchased Turbo Pascal 2, and had several decent contracts writing various sorts of software.

In 1985 I wrote a simple programmers text editor in it (I really had no idea what I was doing - I learned as I went along), and released it as shareware.

Folks started sending me checks, and by 1988 I had to hire staff to help me process and ship orders, do tech support, and so on.

We peaked at 15 employees in the mid-90's. While I eventually converted everything to C, I still have very fond memories of Turbo Pascal. Those were the days!
