2025-09-12Bump Prism version to 1.5.0Takashi Kokubun
2025-08-27When reading from stdin, put a wrapper around the IO objectAaron Patterson
The purpose of this commit is to fix Bug #21188. We need to detect when stdin has run in to an EOF case. Unfortunately we can't _call_ the eof function on IO because it will block. Here is a short script to demonstrate the issue: ```ruby x = STDIN.gets puts x puts x.eof? ``` If you run the script, then type some characters (but _NOT_ a newline), then hit Ctrl-D twice, it will print the input string. Unfortunately, calling `eof?` will try to read from STDIN again causing us to need a 3rd Ctrl-D to exit the program. Before introducing the EOF callback to Prism, the input loop looked kind of like this: ```ruby loop do str = STDIN.gets process(str) if str.nil? p :DONE end end ``` Which required 3 Ctrl-D to exit. If we naively changed it to something like this: ```ruby loop do str = STDIN.gets process(str) if STDIN.eof? p :DONE end end ``` It would still require 3 Ctrl-D because `eof?` would block. In this patch, we're wrapping the IO object, checking the buffer for a newline and length, and then using that to simulate a non-blocking eof? method. This commit wraps STDIN and emulates a non-blocking `eof` function. [Backport #21188]

2024-12-16[ruby/prism] Fix 3112 - disallow commas after block argeileencodes
Prism was already disallowing arguments after block args, but in parse.y, any comma after a block arg is a syntax error. This moves the error handling into `PM_TOKEN_UAMPERSAND` where we can check if the current type is `PM_TOKEN_COMMA`then raise an error. I've also updated the tests to include the examplesfrom ruby/prism#3112. Fixes: ruby/prism#3112 https://github.com/ruby/prism/commit/754cf8eddc Notes: Merged: https://github.com/ruby/ruby/pull/12358

2024-12-12[ruby/prism] Same numbered param cannot be used in child blocksAaron Patterson

2024-12-11[ruby/prism] Fix percent delimiter strings with crlfseileencodes
parse.y treats CRLF as a LF and basically "normalizes" them before parsing. That means a string like `%\nfoo\r\n` is actually treated as `%\nfoo\n` for the purposes of parsing. This happens on both the opening side of the percent string as well as on the closing side. So for example `%\r\nfoo\n` must be treated as `%\nfoo\n`. To handle this in Prism, when we start a % string, we check if it starts with `\r\n`, and then consider the terminator to actually be `\n`. Then we check if there are `\r\n` as we lex the string and treat those as `\n`, but only in the case the start was a `\n`.

2024-12-05[ruby/prism] Fix error messages for unterminated ( and {Aaron Patterson
If we hit an EOF token, and the character before the EOF is a newline, we should make EOF token start at the previous newline. That way any errors reported will occur on that line. For example "foo(\n" should report an error on line 1 even though the EOF technically occurs on line 2.
