On creating a poetic programming language.

1 A more in-depth overview can be found in this paper (130 KB), written for the Electronic Literature Organization conference in May 2022.

The project first took root in a thesis preparation course, during which I created an early proposal for the language, titled e?xpress. During the thesis studio course, I developed the project further and documented the semester of making in this project log. As part of the process, I also created five prototypes and documented the feedback sessions for them.


Coem (a portmanteau of “code” and “poem”) is an esoteric programming language that seeks to explore ways that poetry can be made purposeful, and ways that code can be made emotional. Drawing inspiration from codeworks, electronic literature, and critical code studies, it strives to bring together the areas of programming, poetry, linguistics, and typography in ways that are interesting, beautiful, and emotional. In feminist opposition to impersonal tech, it foregrounds ambiguity and connections, emotional and metaphorical significance, textual elements, and personal computing.

The project explores questions such as:

This is a programming language without mathematical operations, which means that it is not Turing-complete. Rather, being composed mainly of declarative statements, it is an experiment in truth and expression.



Codeworks are a broad category that includes code poetry and esoteric programming languages.

Code poetry is poetry written using the conventions of various programming languages, whether or not they compile and run as valid programs in the language.

Esoteric programming languages—esolangs, for short—are hobbyist projects that challenge and play with the norms of computing. An ongoing open wiki documents new esolangs, and Daniel Temkin maintains a blog on that feature detailed write-ups about esolangs and interviews with their creators. Examples of esolangs that have particularly inspired this project are:

Electronic literature

Electronic literature is an even broader category that covers much of born-digital works, including interactive fiction and non-linear narratives.

Critical code studies

Pioneered by Mark C. Marino with his seminal book, critical code studies describes what it means to critically engage with code. Rather than focusing on the effects of code, this approach focuses on code as a text on its own.


Regular expressions

In a paper titled “Regular Expressions as a System of Poetic Notation”, Dan Waber writes about the poetic potential of regular expressions. He describes “a system of notation to augment, to build upon, to multiply the possibilities of language to make nets for catching truth.” Strikingly, he writes, “When reading about regular expressions substitute the word ‘means’ wherever the word ‘matches’ occurs and the text will become about poetics.”


Coem is a language without mathematical operations. One consequence of this is that words and symbols are open to re-interpretation, in consideration of both programming and literary contexts.

Typography and syntax highlighting

Coem is a programming language focusing on words, symbols, and typography. Syntax highlighting is a feature of text editors that displays text in different colors and fonts to help with scanning, comprehension, and error identification. In the Coem web editor, font styles and limited colors are used to signify and differentiate tokens.

Interaction directives

Borrowing from the tradition of preprocessor directives in languages such as C and C++, this language features directives that let you customise how the machine interprets and interacts with you. They range from the functional, such as the palimpsest feature that retains a variable’s history, to the emotional, such as the be gentle feature that softens error messages.


This language is currently under development as part of the author’s senior thesis. The author hopes to continue developing it beyond the duration of the course, and invites input and collaboration!
