Question

我想在cmake中使用mustache作为简单的模板引擎来生成代码。

我尝试使用execute_process执行它，如下所示：

execute_process( COMMAND "/path/to/mustache" "<data> <template>" )

但它说它不是一个有效的WIN32应用程序。事实上，小胡子是一个红宝石剧本：

#!D:/programs/Ruby23/bin/ruby.exe
#
# This file was generated by RubyGems.
#
# The application 'mustache' is installed as part of a gem, and
# this file is here to facilitate running it.
#

require 'rubygems'

version = ">= 0.a"

if ARGV.first

    ...

所以我试过了：

execute_process( COMMAMD "/path/to/ruby" "/path/to/mustache --help" )

但它不起作用...... No such file or directory -- D:/programs/Ruby23/bin/mustache --help (LoadError)

如何在cmake execute_process中执行ruby脚本？

Answer 1

execute_process（COMMAND＆lt; cmd1＆gt; [args1 ...]] ...）

参数必须作为列表传递，而不是作为字符串传递。

    # path to executables
    set(RUBY_EXECUTABLE D:/programs/Ruby23/bin/ruby.exe CACHE STRING "ruby executable")
    set(MUSTACHE_SCRIPT D:/programs/Ruby23/bin/mustache CACHE STRING "mustache ruby script")

    # function that call mustache
    function(apply_mustache data template result)
        execute_process(
            COMMAND ${RUBY_EXECUTABLE} -E UTF-8 ${MUSTACHE_SCRIPT} ${data} ${template}
            OUTPUT_VARIABLE result_t
            )
        set(${result} ${result_t} PARENT_SCOPE)
    endfunction()

奖励：-E UTF-8防止红宝石乱用utf-8字符......

在cmake execute_process
