feedback option
where option may be one of the following:
- add text [style]
- Create a new feedback area inside the cursor box. The feedback entry will be associated with the text text, which will be reported on execution of a feedback why query. The feedback area will be drawn in style style, which may be one of the following:
- dotted
- medium
- outline
- pale
- solid
- clear
- Clear all feedback info
- count
- Count the number of feedback entries
- find [nth]
- Put the cursor box over next (or nth) entry
- help
- Print help information
- save file
- Save feedback area information into file file
- why
- Print text associated with all feedback areas under the cursor box.
The feedback command queries or manipulates feedback areas, which are areas drawn on top of the layout and may be used for annotations and markers. Internally, magic uses feedback areas to report CIF/GDS layers (cif see command), and errors generated by the extract command. CIF/GDS feedback is placed on the output (usually centimicron) grid, which cannot be done with the feedback add command directly from the command-line.Feedback information and areas are not saved in the layout file.
feedback is implemented as a built-in magic command.
Small feedback areas are drawn solid to prevent them from disappearing entirely; however, this creates bizarre results in CIF/GDS feedback when several narrow feedback areas are tiled together.There should be a mechanism for removing only the feedback entries under the cursor box, or the current feedback entry.
