Scripting API

CopyQ provides scripting capabilities to automatically handle clipboard changes, organize items, change settings and much more.

Supported language features and base function can be found at ECMAScript Reference. The language is mostly equivalent to modern JavaScript. Some features may be missing but feel free to use for example JavaScript reference on MDN.

CopyQ-specific features described in this document:

Note

These terms are equivalent: format, MIME type, media type

Execute Script

The scripts can be executed from:

  1. Action or Command dialogs (F5, F6 shortcuts), if the first line starts with copyq:
  2. command line as copyq eval '<SCRIPT>'
  3. command line as cat script.js | copyq eval -
  4. command line as copyq <SCRIPT_FUNCTION> <FUNCTION_ARGUMENT_1> <FUNCTION_ARGUMENT_2> ...

When run from command line, result of last expression is printed on stdout.

Command exit values are:

  • 0 - script finished without error
  • 1 - fail() was called
  • 2 - bad syntax
  • 3 - exception was thrown

Command Line

If number of arguments that can be passed to function is limited you can use

copyq <FUNCTION1> <FUNCTION1_ARGUMENT_1> <FUNCTION1_ARGUMENT_2> \
          <FUNCTION2> <FUNCTION2_ARGUMENT> \
              <FUNCTION3> <FUNCTION3_ARGUMENTS> ...

where <FUNCTION1> and <FUNCTION2> are scripts where result of last expression is functions that take two and one arguments respectively.

Example:

copyq tab clipboard separator "," read 0 1 2

After eval() no arguments are treated as functions since it can access all arguments.

Arguments recognize escape sequences \n (new line), \t (tabulator character) and \\ (backslash).

Argument -e is identical to eval().

Argument - is replaced with data read from stdin.

Argument -- is skipped and all the remaining arguments are interpreted as they are (escape sequences are ignored and -e, -, -- are left unchanged).

Functions

Argument list parts ... and [...] are optional and can be omitted.

Comment /*set*/ in function declaration indicates a specific function overload.

Item row values in scripts always start from 0 (like array index), unlike in GUI, where row numbers start from 1 by default.

Types

class ByteArray()

Wrapper for QByteArray Qt class.

See QByteArray.

ByteArray is used to store all item data (image data, HTML and even plain text).

Use str() to convert it to string. Strings are usually more versatile. For example to concatenate two items, the data need to be converted to strings first.

var text = str(read(0)) + str(read(1))
class File()

Wrapper for QFile Qt class.

See QFile.

To open file in different modes use:

  • open() - read/write
  • openReadOnly() - read only
  • openWriteOnly() - write only, truncates the file
  • openAppend() - write only, appends to the file

Following code reads contents of “README.md” file from current directory:

var f = new File('README.md')
if (!f.openReadOnly())
  throw 'Failed to open the file: ' + f.errorString()
var bytes = f.readAll()

Following code writes to a file in home directory:

var dataToWrite = 'Hello, World!'
var filePath = Dir().homePath() + '/copyq.txt'
var f = new File(filePath)
if (!f.openWriteOnly() || f.write(dataToWrite) == -1)
  throw 'Failed to save the file: ' + f.errorString()

// Always flush the data and close the file,
// before opening the file in other application.
f.close()
class Dir()

Wrapper for QDir Qt class.

Use forward slash as path separator, for example “D:/Documents/”.

See QDir.

class TemporaryFile()

Wrapper for QTemporaryFile Qt class.

See QTemporaryFile.

var f = new TemporaryFile()
f.open()
f.setAutoRemove(false)
popup('New temporary file', f.fileName())

To open file in different modes, use same open methods as for File.

class Item()

Object with MIME types of an item.

Each property is MIME type with data.

Example:

var item = {}
item[mimeText] = 'Hello, World!'
item[mimeHtml] = '<p>Hello, World!</p>'
write(mimeItems, pack(item))
class ItemSelection()

List of items from given tab.

An item in the list represents the same item in tab even if it is moved to a different row.

New items in the tab are not added automatically into the selection.

To create new empty selection use ItemSelection() then add items with select*() methods.

Example - move matching items to the top of the tab:

ItemSelection().select(/^prefix/).move(0)

Example - remove all items from given tab but keep pinned items:

ItemSelection(tabName).selectRemovable().removeAll();

Example - modify items containing “needle” text:

var sel = ItemSelection().select(/needle/, mimeText);
for (var index = 0; index < sel.length; ++index) {
    var item = sel.itemAtIndex(index);
    item[mimeItemNotes] = 'Contains needle';
    sel.setItemAtIndex(item);
}

Example - selection with new items only:

var sel = ItemSelection().selectAll()
add("New Item 1")
add("New Item 2")
sel.invert()
sel.items();

If regexp is undefined and mimeType is set, this select items not containing the MIME type.

Returns:self
Return type:ItemSelection

// Print a message if COPYQ_LOG_LEVEL=DEBUG
// environment variable is set
console.log(
    'Supported console properties/functions:',
    Object.getOwnPropertyNames(console))
console.warn('Changing clipboard...')

// Elapsed time
console.time('copy')
copy('TEST')
console.timeEnd('copy')

// Ensure a condition is true before continuing
console.assert(str(clipboard()) == 'TEST')

MIME Types

Item and clipboard can provide multiple formats for their data. Type of the data is determined by MIME type.

Here is list of some common and builtin (start with application/x-copyq-) MIME types.

These MIME types values are assigned to global variables prefixed with mime.

Note

Content for following types is UTF-8 encoded.

mimeText

Data contains plain text content.

mimeHtml

Data contains HTML content.

mimeUriList

Data contains list of links to files, web pages etc.

mimeWindowTitle

Current window title for copied clipboard.

mimeItems

Serialized items.

mimeItemNotes

Data contains notes for item.

mimeIcon

Data contains icon for item.

mimeOwner

If available, the clipboard was set from CopyQ (from script or copied items).

Such clipboard is ignored in CopyQ, i.e. it won’t be stored in clipboard tab and automatic commands won’t be executed on it.

mimeClipboardMode

Contains selection if data is from Linux mouse selection.

mimeCurrentTab

Current tab name when invoking command from main window.

Following command print the tab name when invoked from main window:

copyq data application/x-copyq-current-tab
copyq selectedTab
mimeSelectedItems

Selected items when invoking command from main window.

mimeCurrentItem

Current item when invoking command from main window.

mimeHidden

If set to 1, the clipboard or item content will be hidden in GUI.

This won’t hide notes and tags.

Example – clear window title and tool tip:

copyq copy application/x-copyq-hidden 1 plain/text "This is secret"
mimeShortcut

Application or global shortcut which activated the command.

copyq:
var shortcut = data(mimeShortcut)
popup("Shortcut Pressed", shortcut)
mimeColor

Item color (same as the one used by themes).

Examples:

#ffff00
rgba(255,255,0,0.5)
bg - #000099
mimeOutputTab

Name of the tab where to store new item.

The clipboard data will be stored in tab with this name after all automatic commands are run.

Clear or remove the format to omit storing the data.

Example – automatic command that avoids storing clipboard data:

removeData(mimeOutputTab)

Valid only in automatic commands.

Selected Items

Functions that get and set data for selected items and current tab are only available if called from Action dialog or from a command which is in menu.

Selected items are indexed from top to bottom as they appeared in the current tab at the time the command is executed.

Linux Mouse Selection

In many application on Linux, if you select a text with mouse, it’s possible to paste it with middle mouse button.

The text is stored separately from normal clipboard content.

On non-Linux system, functions that support mouse selection will do nothing (for example copySelection()) or return undefined (in case of selection()).

Plugins

Use plugins object to access functionality of plugins.

plugins.itemsync.selectedTabPath()

Returns synchronization path for current tab (mimeCurrentTab).

var path = plugins.itemsync.selectedTabPath()
var baseName = str(data(plugins.itemsync.mimeBaseName))
var absoluteFilePath = Dir(path).absoluteFilePath(baseName)
// NOTE: Known file suffix/extension can be missing in the full path.
class plugins.itemsync.tabPaths()

Object that maps tab name to synchronization path.

var tabName = 'Downloads'
var path = plugins.itemsync.tabPaths[tabName]
plugins.itemsync.mimeBaseName

MIME type for accessing base name (without full path).

Known file suffix/extension can be missing in the base name.

plugins.itemtags.userTags

plugins.itemtags.tags(row, ...)
