Next: , Previous: , Up: Scheme Syntax   [Contents][Index] Case Sensitivity

Scheme as defined in R5RS is not case sensitive when reading symbols. Guile, on the contrary is case sensitive by default, so the identifiers


are the same in R5RS Scheme, but are different in Guile.

It is possible to turn off case sensitivity in Guile by setting the reader option case-insensitive. For more information on reader options, See Scheme Read.

(read-enable 'case-insensitive)

It is also possible to disable (or enable) case sensitivity within a single file by placing the reader directives #!fold-case (or #!no-fold-case) within the file itself.
