how to use conditional for template?

[pplmx]

Here is my config, which doesn't work.

Two issues:

1. ignore doesn't work, the files who should be ignored always exist in the new project
   I also tried exclude feature, it still didn't work
2. when project-type == lib, lib-type prompt doesn't appear.

The whole code

[template]
cargo_generate_version = ">=0.10.0"

[placeholders.gh-username]
type = "string"
prompt = "GitHub username (or organization)?"
# The username cannot end with a hyphen, too, but
# this requirement is not captured by the regex at the moment.
regex = "^[A-Za-z0-9][A-Za-z0-9-]{0,38}$"

[placeholders.project-description]
type = "string"
prompt = "Project description?"

[placeholders.cmake-min-version]
type = "string"
prompt = "CMake minimum version?"
regex = "^[0-9]+(\\.[0-9]+){0,2}$"

[placeholders.cxx-standard]
type = "string"
prompt = "Cxx standard version?"
regex = "^[0-9]+$"

[placeholders.project-type]
type = "string"
prompt = "Which cxx project type?"
choices = [
    "bin",
    "lib"
]
default = "bin"

[conditional.'project-type == "bin"']
ignore = ["src/library.h", "src/library.cpp"]

[conditional.'project-type == "lib"'.placeholders.lib-type]
ignore = ["src/main.cpp"]
type = "string"
prompt = "Which lib type?"
choices = ["static", "shared"]
default = "shared"

cmake_minimum_required(VERSION {{cmake-min-version}})
project({{project-name}})

set(CMAKE_CXX_STANDARD {{cxx-standard}})

{% if project-type == "bin" -%}
add_executable({{project-name}} src/main.cpp)
{%- else -%}
{%- if lib-type == "static" -%}
# static
add_library({{project-name}} src/library.cpp)
{%- else -%}
# shared
add_library({{project-name}} SHARED src/library.cpp)
{%- endif %}
{%- endif %}

After renaming all variables: replace - with _
It works fine.

FYI. Here is my final config.

[template]
cargo_generate_version = ">=0.10.0"

[placeholders.gh_uname]
type = "string"
prompt = "GitHub username (or organization)?"
# The username cannot end with a hyphen, too, but
# this requirement is not captured by the regex at the moment.
regex = "^[A-Za-z0-9][A-Za-z0-9-]{0,38}$"

[placeholders.proj_description]
type = "string"
prompt = "Project description?"

[placeholders.cmake_min_version]
type = "string"
prompt = "CMake minimum version?"
regex = "^[0-9]+(\\.[0-9]+){0,2}$"

[placeholders.cxx_standard_version]
type = "string"
prompt = "Cxx standard version?"
regex = "^[0-9]+$"

[placeholders.proj_type]
type = "string"
prompt = "Which cxx project type?"
choices = ["bin", "lib"]
default = "bin"

[conditional.'proj_type == "lib"'.placeholders.lib_type]
type = "string"
prompt = "Which lib type?"
choices = ["static", "shared"]
default = "shared"

[conditional.'proj_type == "bin"']
ignore = ["src/library.h", "src/library.cpp"]

[conditional.'proj_type == "lib"']
ignore = ["src/main.cpp"]

cmake_minimum_required(VERSION {{cmake_min_version}})
project({{project-name}})

set(CMAKE_CXX_STANDARD {{cxx_standard_version}})

{% if proj_type == "bin" -%}
add_executable({{project-name}} src/main.cpp)
{%- else -%}
{%- if lib_type == "static" -%}
# static
add_library({{project-name}} src/library.cpp)
{%- else -%}
# shared
add_library({{project-name}} SHARED src/library.cpp)
{%- endif %}
{%- endif %}
