Substitutes accented characters (Latin1 and UTF-8) in strings by either non accented ASCII characters or HTML entities.
The current supported accented characters for both latin1 and UTF-8 are: ã, Ã, á, Á, â, Â, à, À, ä, Ä, é, É, ê, Ê, è, È, ë, Ë, í, Í, î, Î, ì, Ì, ï, Ï, õ, Õ, ó, Ó, ô, Ô, ò, Ò, ö, Ö, ú, Ú, û, Û, ù, Ù, ü, Ü, ç and Ç.
The following characters are supported in UTF-8 only: İ, ı, Ğ, ğ, Ş, ş.
If you want to replace accented characters in Latin-1 strings, use:
(require-extension accents-substitute-latin1) (accents-substitute "ação") => "acao" (accents-substitute "ação" mode: 'html) => "ação"
If you want to replace accented characters in UTF-8 strings, use:
(require-extension accents-substitute-utf8) (accents-substitute "ação") => "acao" (accents-substitute "ação" mode: 'html) => "ação"
- accents-substitute str #!key modeprocedure
Substitute accented characters in str by non accented ASCII characters (if mode is not given or is given as 'ascii) or by HTML entities (if mode is given as 'html).
- accents-substitute-latin1 str #!key modeprocedure
Substitute Latin-1 accented characters in str by non accented ASCII characters (if mode is not given or is given as 'ascii) or by HTML entities (if mode is given as 'html).
- accents-substitute-utf8 str #!key modeprocedure
Substitute UTF-8 accented characters in str by non accented ASCII characters (if mode is not given or is given as 'ascii) or by HTML entities (if mode is given as 'html).
Below you can see the code of a practical command line tool which uses accents-substitute.
Here's how to use it:
Usage: accents-substitute [ --encoding=<utf8|latin1> ] [ --mode=<ascii|html> ] [ input file ] Default values: mode: ascii encoding: utf8
Here's the code:
#!/bin/sh #| -*- scheme -*- exec csi -s $0 "$@" |# (use (rename accents-substitute-latin1 (accents-substitute accents-substitute-latin1)) (rename accents-substitute-utf8 (accents-substitute accents-substitute-utf8))) (use posix regex (srfi 1 13)) (define (command-line-argument option args) ;; Return the argument associated to the command line option OPTION ;; in ARGS or #f if OPTION is not found in ARGS or doesn't have any ;; argument. (let ((val (any (cut string-match (string-append option "=(.*)") <>) args))) (and val (cadr val)))) (define (usage #!optional exit-code) (print "Usage: " (pathname-strip-directory (program-name)) " [ --encoding=<utf8|latin1> ] [ --mode=<ascii|html> ] [ input file ]") (print "\nDefault values:\n" " mode: ascii\n" " encoding: utf8") (when exit-code (exit exit-code))) (let* ((args (command-line-arguments)) (mode (command-line-argument "--mode" args)) (encoding (command-line-argument "--encoding" args)) (paramless-args (remove (cut string-prefix? "--" <>) args)) (accents-substitute accents-substitute-utf8)) (when (or (member "-h" args) (member "--help" args)) (usage 0)) (when (and encoding (not (member encoding '("utf8" "latin1")))) (print "'" encoding "' is not a valid encoding.") (exit 1)) (when (and mode (not (member mode '("ascii" "html")))) (print "'" mode "' is not a valid mode.") (exit 1)) (when (equal? encoding "latin1") (set! accents-substitute accents-substitute-latin1)) (let ((port (if (null? paramless-args) (current-input-port) (open-input-file (car paramless-args))))) (let loop () (let ((line (read-line port))) (unless (eof-object? line) (print (accents-substitute line mode: (and mode (string->symbol mode)))) (loop)))) (unless (null? paramless-args) (close-input-port port))))

- Drop dependency on the regex egg (use irregex unit)
- CHICKEN 5 support
- Fix .release-info
- Fix build order of modules
- Compiled with -O3
- Install the accents-substitute module, which provides procedures to substitute Latin-1 and UTF-8 accented-characters (as a side-effect, this change also fixes the chicken-install reinstallation problem)
- Added UTF-8 support for turkish characters (İ, ı, Ğ, ğ, Ş, ş). Thanks to Mehmet Köse.
- Use pre compiled regexes for html mode (a lot faster). Added regex requirement for compatibility with chickens >= 4.6.2.
- Initial release
