---Add tags.
---
---If you need to add the names as a table, use `tag.add_table` instead.
---
---You can also do `op:add_tags(...)`.
---
---### Example
---
---```lua
---local op = output.get_by_name("DP-1")
---if op ~= nil then
--- tag.add(op, "1", "2", "3", "4", "5") -- Add tags with names 1-5
---end
---```
---@param output Output The output you want these tags to be added to.
---@param ... string The names of the new tags you want to add.
function tag.add(output, ...)
local tag_names = table.pack(...)
tag_names["n"] = nil -- remove the length to make it a true array for serializing
SendMsg({
AddTags = {
output_name = output.name,
tag_names = tag_names,
},
})
end
---Like `tag.add`, but with a table of strings instead.
---
---### Example
---
---```lua
---local tags = { "Terminal", "Browser", "Mail", "Gaming", "Potato" }
---local output = output.get_by_name("DP-1")
---if output ~= nil then
--- tag.add(output, tags) -- Add tags with the names above
---end
---```
---@param output Output The output you want these tags to be added to.
---@param names string[] The names of the new tags you want to add, as a table.
function tag.add_table(output, names)
SendMsg({
AddTags = {
output_name = output.name,
tag_names = names,
},
})
end
---Toggle a tag on the specified output. If `output` isn't specified, toggle it on the currently focused output instead.
---
---### Example
---
---```lua
----- Assuming all tags are toggled off...
---local op = output.get_by_name("DP-1")
---tag.toggle("1", op)
---tag.toggle("2", op)
----- will cause windows on both tags 1 and 2 to be displayed at the same time.
---```
---@param name string The name of the tag.
---@param output Output? The output.
function tag.toggle(name, output)
if output ~= nil then
SendMsg({
ToggleTag = {
output_name = output.name,
tag_name = name,
},
})
else
local op = require("output").get_focused()
if op ~= nil then
SendMsg({
ToggleTag = {
output_name = op.name,
tag_name = name,
},
})
end
end
end
---Switch to a tag on the specified output, deactivating any other active tags on it.
---If `output` is not specified, this uses the currently focused output instead.
---
---This is used to replicate what a traditional workspace is on some other Wayland compositors.
---
---### Example
---
---```lua
---tag.switch_to("3") -- Switches to and displays *only* windows on tag 3
---```
---@param name string The name of the tag.
---@param output Output? The output.
function tag.switch_to(name, output)
if output ~= nil then
SendMsg({
SwitchToTag = {
output_name = output.name,
tag_name = name,
},
})
else
local op = require("output").get_focused()
if op ~= nil then
SendMsg({
SwitchToTag = {
output_name = op.name,
tag_name = name,
},
})
end
end
end
---Set a layout for the tag on the specified output. If there is none, set it for the tag on the currently focused one.
---@param name string The name of the tag.
---@param layout Layout The layout.
---@param output Output? The output.
function tag.set_layout(name, layout, output)
if output ~= nil then
SendMsg({
SetLayout = {
output_name = output.name,
tag_name = name,
layout = layout,
},
})
else
local op = require("output").get_focused()
if op ~= nil then
SendMsg({
SetLayout = {
output_name = op.name,
tag_name = name,
layout = layout,
},
})
end
end
end
---Get all tags on the specified output.
---
---You can also use `output_obj:tags()`, which delegates to this function:
---```lua
---local tags_on_output = output.get_focused():tags()
----- This is the same as
----- local tags_on_output = tag.get_on_output(output.get_focused())
---```
---@param output Output
---@return Tag[]
function tag.get_on_output(output)
SendRequest({
GetTagsByOutput = {
output_name = output.name,
},
})
local response = ReadMsg()
local tag_ids = response.RequestResponse.response.Tags.tag_ids
---@type Tag[]
local tags = {}
for _, tag_id in pairs(tag_ids) do
table.insert(tags, new_tag({ id = tag_id }))
end
return tags
end
---Get all tags with this name across all outputs.
---@param name string The name of the tags you want.
---@return Tag[]
function tag.get_by_name(name)
SendRequest({
GetTagsByName = {
tag_name = name,
},
})
local response = ReadMsg()
local tag_ids = response.RequestResponse.response.Tags.tag_ids
---@type Tag[]
local tags = {}
for _, tag_id in pairs(tag_ids) do
table.insert(tags, new_tag({ id = tag_id }))
end
return tags
end
return tag
