# September 9th, 2016
|
||||
|
||||
- Hack week was last week and we skipped the weekly.
|
||||
- We moved the weekly to the end of the week to try to cut down on the “wait, what _did_ happen last week?” thing.
|
||||
- This ended up being @tclem’s first weekly 👋
|
||||
|
||||
|
||||
#### What went well?
|
||||
|
||||
@joshvera:
|
||||
|
||||
Hack week:
|
||||
|
||||
- Made a lot of progress on the TypeScript parser.
|
||||
- May be able to use that as the basis for a more rigorous JavaScript parser as well.
|
||||
|
||||
This week:
|
||||
|
||||
- Understand RWS & some other diffing algos a lot better than before.
|
||||
|
||||
|
||||
@rewinfrey:
|
||||
|
||||
- Pairing w/ @tclem.
|
||||
- Updating test cases is much more efficient.
|
||||
- Modelling effects in Free.
|
||||
|
||||
|
||||
@tclem:
|
||||
|
||||
- Little fixes.
|
||||
- Static linking of ICU in dev.
|
||||
- statsd client.
|
||||
|
||||
|
||||
@robrix:
|
||||
|
||||
- semantic-diffd
|
||||
- Docker
|
||||
- kubes
|
||||
- Markdown
|
||||
|
||||
|
||||
#### What were the challenges?
|
||||
|
||||
@joshvera:
|
||||
|
||||
- Integrating a pass before RWS. Using constant-time (per-subtree)SES before RWS to match up equal things. There are some ordering problems with the result.
|
||||
- Ambiguities in the TypeScript grammar. Possibly due to JS actually being context-sensitive. @maxbrunsfeld advises parsing a superset of the language… but which superset?
|
||||
|
||||
|
||||
@rewinfrey:
|
||||
|
||||
- Trying to get an effect system in Free. Got it, but tricky.
|
||||
- Also picked up an issue with template strings which defies debugging.
|
||||
|
||||
|
||||
@tclem:
|
||||
|
||||
- > My head hurts by the end of the day.
|
||||
- Being challenged by some of the new concepts, the vernacular &c.
|
||||
- Hard to know when to jump down the rabbit hole and learn a thing or when to gloss over it.
|
||||
- Have a queue of things to read.
|
||||
|
||||
|
||||
@robrix:
|
||||
|
||||
- Converting between line/column ranges and character ranges.
|
||||
|
||||
|
||||
#### What did you learn?
|
||||
|
||||
@joshvera:
|
||||
|
||||
- > I became one with the TypeScript grammar.
|
||||
- > Maybe we should find a way to have the grammars write themselves.
|
||||
- Working on this `effects` package (formerly called `freer`) & its `Eff` type. It uses an open union data structure, which `Data.Record` is sort of an approximation of. `Eff` has this detail where it’s list of function types are “type-aligned.” Every item in the list is a function type where they all chain together, a -> b, b -> c, etc. Adding, removing, & replacing effects is constant-time.
|
||||
|
||||
@rewinfrey:
|
||||
|
||||
- Free, and how to model effects in Free.
|
||||
- Straight-up category theory stuff. Compositions of natural transformations &c.
|
||||
|
||||
@tclem:
|
||||
|
||||
- Post about functors, applicatives, and monads shown in pictures.
|
||||
- How this manages to be a bridge between pure & stateful functions.
|
||||
- Helped explain the optparse-applicative syntax.
|
||||
|
||||
@robrix:
|
||||
|
||||
- CMark exists, which is cool.
|
||||
- Parsing/term ingestion had been producing errors for weirdly-formatted for loops &c. Not only were we hitting this on a regular basis, it was also causing confusing/poor change summaries.
|
||||
|
||||
|
||||
#### Meta
|
||||
|
||||
“What were the challenges?” can be a bit redundant with “what did you learn?” Should we focus this on challenges that we need help with? Gonna give that a try.
|
||||
|
||||
Next week: @joshvera, @rewinfrey, & @robrix are off to ICFP. @tclem may or may not hold weekly solo at his discretion.
