Seer

How to add a plugin

1. To install a plugin, select it in the Settings and hit the Download button afterwards. This initiates the download of the plugin file in default system browser.
   
2. All plugins are provided as zip archives which you need to extract on the local system.
3. Afterwards, switch to the Local tab under Plugins in Seer's Settings, and click on add. This opens a file browser which you use to select the json file in the folder you have extracted the archive to.
   
4. Once done, support for the new file types has been added to Seer.
   

• The extension of file is case insensitive
• Drag line number to change sequence
• Triggered only check the plug-in type once

How to write a plugin

Replace invocation

Seer simply replaces *SEER_INPUT_PATH* with the triggered file, replaces *SEER_OUTPUT_PATH* with the saving path. If the plugin output file doesn't contain a suffix, you can append suffix to the *SEER_OUTPUT_PATH*.

In practical use, it looks like this:

nconvert.exe -out pdf -o *SEER_OUTPUT_PATH*.pdf *SEER_INPUT_PATH*

Source code for example

• fontpreview
• MS-Office

Raw python script invocation

1. plugin json file: "exec": "python.exe \"E:\\your_execable_fullpath.py\" \"*SEER_INPUT_PATH*\" \"*SEER_OUTPUT_PATH*\""
2. move the plugin.json to python.exe folder
3. add plugin.json to Seer
