batchTextEdit.jsx

// batchTextEdit.jsx
// adobe Illustrator CSx script
// for editing the contents of the text frames all together.
//
// Usage:
// 1. Select the textframe(s) and run this script.
// 2. Edit the contents in the dialog. Then hit OK button.
//
// Notice:
// * The attribute of the first character is applied to whole
//   contents of textframe if you run this script for it.
//   It is assumed that each contents is plain text.
// 
// * For the multiline contents, the return code characters are
//   replaced to the alternative ones (default:"@/") in the dialog.
//   When applying the edited contents, they are replaced to
//   the return code. This means you can't use "@/" itself in the
//   contents. You can change it in the setting part of the script.
//
// * The order of the texts in the dialog depends on the rectangle
//   area surrounding each top-left corner of the selected textframes.
//   If the width of the area is greater than the height of it, the
//   order is from left to right. Otherwise from top to bottom.

// test env: Adobe Illustrator CS3, CS6 (Windows)
