| 70 | % GetScriptToken() is fairly general, finite state token parser. That will |
| 71 | % divide a input file stream into tokens, in a way that is almost identical |
| 72 | % to a UNIX shell. |
| 73 | % |
| 74 | % It returns 'MagickTrue' if a token was found. Even in the special case of |
| 75 | % a empty token followed immediatally by a EOF. For example: ''{EOF} |
| 76 | % |
| 77 | % A token is returned immediatally the end of token is found. That is |
| 78 | % parsing is purely character by character, and not line-by-line. This |
| 79 | % should allow for mixed stream of tokens (options), and other data (images) |
| 80 | % without problems. Assuming the other data has a well defined End-Of-Data |
| 81 | % handling (see complex example below). |
| 82 | % |
| 83 | % Tokens are white space separated, and may be quoted, or even partially |
| 84 | % quoted by either single or double quotes, or the use of backslashes, |
| 85 | % or any mix of the three. |
| 86 | % |
| 87 | % For example: This\ is' a 'single" token" |
| 88 | % |
| 89 | % Single quotes will preserve all characters including backslashes. Double |
| 90 | % quotes will also preserve backslashes unless escaping a double quote, |
| 91 | % or another backslashes. Other shell meta-characters are not treated as |
| 92 | % special by this tokenizer. |
| 93 | % |
| 94 | % For example Quoting the quote chars: |
| 95 | % \' "'" \" '"' "\"" \\ '\' "\\" |
| 96 | % |
| 97 | % Comments start with a '#' character at the start of a new token (generally |
| 98 | % at start of a line, or after a unquoted white space charcater) and continue |
| 99 | % to the end of line. The are simply ignored. You can escape a comment '#' |
| 100 | % character to return a token that starts with such a character. |
| 101 | % |
| 102 | % More complex example... |
| 103 | % Sending a PGM image in the middle of a standard input script. |
| 104 | % |
| 105 | % magick -script - <<END |
| 106 | % # read a stdin in-line image... |
| 107 | % "pgm:-[0]" P2 2 2 3 0 1 1 2 |
| 108 | % # continue processing that image |
| 109 | % -resize 100x100 |
| 110 | % -write enlarged.png |
| 111 | % END |
| 112 | % |
| 113 | % Only a single space character separates the 'image read' from the |
| 114 | % 'image data' after which the next operation is read. This only works |
| 115 | % for image data formats with a well defined length or End-of-Data marker |
| 116 | % such as MIFF, and PbmPlus file formats. |
