How to Remove Tokens From A List In Cmake?

To remove tokens from a list in CMake, you can use the LIST(REMOVE_ITEM) command. This command allows you to specify the list to remove items from and the tokens you want to remove. For example, if you have a list called myList and you want to remove the tokens "token1" and "token2", you can use the command LIST(REMOVE_ITEM myList "token1" "token2"). This will remove the specified tokens from the list myList.

How to update a list by removing unwanted items in CMake?

In CMake, you can update a list by removing unwanted items by using the LIST(REMOVE_ITEM) and FOREACH command. Here's an example:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

# Initial list
set(myList 1 2 3 4 5)

# Items to remove
set(itemsToRemove 2 4)

# Loop through each item in itemsToRemove
foreach(item ${itemsToRemove})
    # Remove item from myList
    list(REMOVE_ITEM myList ${item})
endforeach()

# Print updated list
message("Updated list: ${myList}")

In this example, we have an initial list myList with items 1-5, and a list itemsToRemove containing items 2 and 4 that we want to remove from myList. We use a FOREACH loop to iterate through each item in itemsToRemove and use the LIST(REMOVE_ITEM) command to remove those items from myList. After the loop is completed, we print the updated list with the unwanted items removed.

How to manipulate lists in CMake to remove specific elements?

In CMake, you can manipulate lists using the "LIST" command. To remove specific elements from a list, you can use a combination of commands like "LIST(FIND)", "REMOVE_ITEM()" and "FOREACH". Here is an example of how you can remove specific elements from a list in CMake:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

# Define a list
set(myList a b c d e)

# Find the index of the element you want to remove
list(FIND myList c index)

if(index EQUAL -1)
    message("Element not found in list")
else()
    # Remove the element at the specified index
    list(REMOVE_AT myList ${index})
endif()

# Print the updated list
message("Updated list: ${myList}")

In this example, the element "c" is removed from the list "myList". You can replace "c" with any other element you want to remove. Just make sure to check if the element exists in the list before trying to remove it.

How to exclude duplicates from a list in CMake?

To exclude duplicates from a list in CMake, you can use the REMOVE_DUPLICATES option in the list command. Here is an example:

1
2
3
4
5
6

set(my_list "a" "b" "c" "a" "b")
list(REMOVE_DUPLICATES my_list)

foreach(item IN LISTS my_list)
    message("${item}")
endforeach()

In this example, the list(REMOVE_DUPLICATES my_list) command will remove any duplicate elements from the my_list variable. After running this command, the list will only contain unique elements.

How to eliminate certain items from a list in CMake?

In CMake, you can use the FILTER_OUT function to eliminate certain items from a list. Here is an example of how to use this function:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11

# Create a list with some items
set(my_list a b c d e)

# List the items you want to eliminate
set(items_to_remove b d)

# Use FILTER_OUT to remove the specified items from the list
list(FILTER my_list EXCLUDE REGEX "(${items_to_remove})")

# Print the updated list
message("Updated list: ${my_list}")

In this example, the FILTER_OUT function is used to remove the items "b" and "d" from the list my_list. The resulting list will be printed out as "a c e".

You can use this method to eliminate any items from a list in CMake by specifying the items you want to remove and using the FILTER_OUT function.

How to filter out empty strings from a list in CMake?

To filter out empty strings from a list in CMake, you can use the FOREACH command along with the IF condition. Here's an example of how you can do this:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

# Initial list with empty strings
set(my_list "foo" "" "bar" "" "baz")

# Create a new list to store non-empty strings
set(filtered_list)

# Iterate over the initial list and add non-empty strings to the filtered list
foreach(item IN LISTS my_list)
  if(NOT "${item}" STREQUAL "")
    list(APPEND filtered_list "${item}")
  endif()
endforeach()

# Print the filtered list
message("Filtered list: ${filtered_list}")

In this example, the foreach loop iterates over each item in the my_list and uses an IF condition to check if the item is not an empty string. If it's not empty, it appends the item to the filtered_list. Finally, the filtered list is printed using the message command.

You can modify and adapt this example based on your specific requirements and the structure of your list.
