Re: JSON without lf?

by Richard O'Keefe

In Json, arbitrary anounts of white space can appear between tokens, including line feed. If this is âpainfulâ for your tests, then itâs unlikely to be the only thing that is. If you are comparing JSON irms *as* JSON, then linefeeds wonât matter . If you are comparing JSON items as strings, there are so many ways that different strrings can represent the same value -infinitely many, in fact - that linefeeds are the least of your worries. What are you actually doing in your tests?

IWST extended abstract

by Steffen MÃ¤rcker

Dear all! Maybe you can help me with this, although it is not a Pharo-question: When submitting to IWST, an extended abstract has to be provided. As far as I understand, an extended abstract should use the CEURART template. Does this mean, that it is essentially a mini-paper with sections and references or shall it be fitted into the abstract environment only? Maybe there is an example I am not aware of. Thanks and kind regards! Steffen

I used the writer instead of the Facade. e.g. ^ String streamContents: [ :s | | writer | writer := STONWriter new. writer on: s. writer jsonMode: true. writer prettyPrint: true; newLine: newline; S > On 10 Apr 2026, at 12:54, stephane ducasse <stephane.ducasse(a)inria.fr> wrote: > > Hi > > I would like to know if there is a way to generate JSON without lf? > > toJsonStringPretty: is generating lf and this is painful for tests. > > S. >

Re: JSON without lf?

by Aaron Wohl

CLAUDE.ai answer: The short answer: use STON toJsonString: obj (no Pretty). It produces compact JSON on a single line with zero line feeds: STON toJsonString: (Dictionary new at: 'foo' put: 1; at: 'bar' put: #(1 2 3); yourself) "=> '{"foo":1,"bar":[1,2,3]}'" Verified byte-level â the output contains no 0x0A (LF) bytes. Why toJsonStringPretty: is flaky for tests. It's a one-liner that delegates to STON jsonWriter with prettyPrint: true. The writer's newline character is set in STONWriter>>initialize: newLine := OSPlatform current lineEnding. So you get LF on macOS/Linux and CRLF on Windows â different expected strings per platform. That's the real source of the pain. If you actually want pretty output but deterministic line endings, build the writer yourself and call newLine: explicitly (it takes any string â CR, LF, CRLF, or even ''): String streamContents: [ :out | ((STON jsonWriter on: out) prettyPrint: true; newLine: String lf; yourself) nextPut: object ] STONWriter>>newLine: is a public accessor, and newlineIndent just writes whatever string you set, so passing String cr, String crlf, or '' all work. I confirmed it by reading STONWriter>>newLine:, newlineIndent, and dumping raw bytes from a pretty run with newLine: String cr â got byte 13, no byte 10. So, for test stability, the two clean answers for the pharo list are: 1. Use `STON toJsonString:` â compact, no newlines, no platform drift. 2. Or configure the writer: `(STON jsonWriter on: s) prettyPrint: true; newLine: String lf; ...` â pretty, but with a line ending you pick instead of the OS default. The base image only ships STON for JSON (no NeoJSON installed), so these are the relevant knobs. ----- Original message ----- From: stephane ducasse via Pharo-users <pharo-users(a)lists.pharo.org> To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Cc: stephane ducasse <stephane.ducasse(a)inria.fr> Subject: [Pharo-users] JSON without lf?

https://soogle.org - SmallTalk only searches for source packages and video

by Aaron Wohl

When learning a new language, I like to read existing code. https://soogle.org collection uses various free (GitHub, walk-specific sites) and paid ($40/month: https://serpapi.com/) sources to collect data. An expensive Anthropic opus-4-6 reviews sampled input and makes up instructions for cheap Anthropic claude-haiku-4-5 check of input to filter out stuff like "Smalltalk how to get a date" and "And Pascal is better than Smalltalk.". open source https://github.com/avwohl/soogle
