Fix ASN.1 lexer: recognize minus sign and fix range operator by h1whelan · Pull Request #3060 · pygments/pygments

h1whelan · 2026-03-12T06:11:57Z

Summary

Fixes #3014 — the ASN.1 lexer was producing an error token for the minus sign in value constraints like (-50..150).

Two issues found and fixed:

Missing - operator: The operator regex didn't include -, so a standalone minus sign (used for negation in value ranges) was not matched by any rule and produced an error token. Fix: add - to the operator alternation.
Float regex consuming .. range operator: The float pattern \d+\.\d* allowed zero digits after the decimal point, so 50..150 was incorrectly tokenized as float 50. + punctuation . + int 150 instead of int 50 + range operator .. + int 150. Fix: require at least one digit after the decimal point (\d+\.\d+).

Test plan

Added tests/snippets/asn1/negative-integer.txt covering Temperature ::= INTEGER (-50..150)
Updated tests/examplefiles/asn1/x509.asn1.output golden file (now correctly tokenizes .. ranges)
All 768 snippet tests pass, all ASN.1 example file tests pass

…tion Two fixes for the ASN.1 lexer: 1. Add `-` to the operator pattern so negative values in constraints like `(-50..150)` are tokenized correctly instead of producing an error token for the minus sign. 2. Require at least one digit after the decimal point in float literals (`\d+\.\d+` instead of `\d+\.\d*`). This prevents `50..150` from being incorrectly tokenized as float `50.` + punctuation `.` + int `150`, instead of the correct int `50` + range `..` + int `150`. Fixes pygments#3014.
