X is a programming language for demonstration purposes. It is coded live on stream.
You can find the video archives on this YouTube playlist.
- Episode 1: discussed design and purpose of the programming language, implemented the parser for variable assignment and function call syntax. (commit)
- Episode 2: implemented built-in runtime functions and user-defined functions. (commit)
- Episode 3: wrote a run script to conviniently execute programs in the X language. Implemented code blocks which are similar to anonymous function expressions in JS, and use that and a runtime $if function to implement conditionals instead of an if statement. (commit)
- Episode 4: implemented array literals,
each,map,filterandreducefunctions and added parameters to code blocks. (commit) - Episode 5: implemented implicit returns and tags for collection types. (commit)
- Episode 6: implemented dictionaries. (commit)
- Episode 7: implemented proper if statements and talked about the dangling else problem. (commit)
- Episode 8: code clean up, string runtime functions, fixed if statement bug, did a code challenge.(commit)
The project depends on this libraries:
