1.0.2 release (April 11, 2024)

This is release 1.0.2 which is an errata release to clarify how defines with lambda expressions and recursion work and to fix the error in the syntax so that display takes an expression.

What's Changed

• Creating an A5 version. by @jrincayc in #39
• Moving note to make it more clear it applies to both sections by @jrincayc in #45
• display should accept an expression by @jrincayc in #47

Thanks go to @jobol and @omasanori for pointing out places where Pico Scheme's specification needed improvement.

1.0.1 release (August 27, 2023)

This is Release 1.0.1, which is mainly an errata release. There are also A4 and A5 versions to in addition to the traditional letter paper size.

Errata fixed:

• Acknowledgements: Clarified that the past editors were prior to R7RS.
• Acknowledgements: Make listing of srfi.schemers.org a url link.
• Acknowledgements: Clarified that The Little Schemer was an inspiration for Pico Scheme.
• 3.1 Added listing define as a variable binding construct.
• 3.4 "choose to any" -> "choose to use any"
• 5.2.2 Clarified that it is an error in R7RS to use define multiple times in the same body. (In Pico Scheme, since it lacks set! this can be handly)
• 6.7 used "may" to clarify output from an expression being an error is optional.
• 6.7 "string or char or port types" -> "string, char or port types"
• 6.7.1 Clarified that pairs only need to be an external representation if they are containing booleans, nulls, numbers, and symbols
• 7.3 Changed or derivation to remove using let which introduced a variable binding x. Note that R7RS cannot use this simpler method because expression can have side effects in R7RS.

Pull requests merged

• Switching srfi to url. by @jrincayc in #37
• Create makefile.yml by @jrincayc in #38
• Combined fixes for 1.0.1 by @jrincayc in #41

RC2 1.0 release candidate

This fixes and clarifies some details (Thanks Elizabeth Cogliati for pointing out the first four).

• Mentions #t when discussing true for first time
• Explain how to use () in program instead of just stating it is not a legal expression.
• fixes missing comma in list
• atom was not defined, so say simple value instead
• pico doesn't have libraries, so removing mention in summary
• None of the R7RS small's SFRI's are actually used in Pico, so remove list.
