我为Google Spreadsheet应用程序开发了几个通用脚本函数。 目前，我将每个功能保存在笔记本电脑上的单个文件中。为了将它们包括在电子表格中，我只知道一种方法。google-apps-script在一个电子表格中有多个脚本
将各个函数文件合并为一个文件。 然后将合并文件中的数据复制并粘贴到 电子表格的脚本编辑器中，替换以前的内容。
这将是很好，如果有一种方法（例如，使用一个“项目”），其中 各个功能文件可以保存一次，然后我可以 只是引用这些功能需要一个新的脚本。
我不知道是否有这种可能性。我在电子表格内容的树列表中只看到一个名为“code”的节点 。
任何帮助表示赞赏。
感谢哔叽。我查看了“图书馆”，这是我发现的。
其中包含一个或多个脚本项目的任何电子表格文件可以作为一个 库引用。 script_project组成了库定义。
电子表格文件可以包含一个或多个script_projects。
在电子表格文件的“工具”菜单 下可以找到脚本功能的接口。该菜单包含与 到脚本三（3）项：
脚本编辑器。 这使您可以访问用于操作的功能： a。 LIBRARY - 具有定义版本号 的脚本PROJECT b。 PROJECT - 一个或多个FILE的集合。 c。 FILE - 一个或多个JavaScript功能的集合。 d。功能 - 一组JavaScript语句，可通过电子表格界面或另一个JavaScript函数 （调用）引用。
When the Script Editor is accessed from a new spreadsheet, it creates
a new (untitled) PROJECT. The new project contains one FILE. The name
of the initial file is "Code". This is the initial "tree" entry under
the "untitled project" root in the left column of the editor's screen.
The contents of the "Code" file is listed in the right column "text_area".
The text_area is initialized with an empty FUNCTION definition which has
the name "myFunction".
The text_area provides normal standard text editing functions that you find
in other script editors (copy, paste, cut; overlay/insert typing text
selection replace(with paste) and delete.
The text_area shows the complete contents of the file. This may be
one or more "function" definitions.
The major functions of the editor in managing PROJECTs and FILEs at
a "higher" level are found under the "File" menu.
The "File" menu contains the following entries:
1. New - This allows you to insert a new PROJECT into the spreadsheet,
or a new FILE in the current PROJECT. It also allows you to
create other types of documents. But I have not explored these
options.
2. Open - This sub-menu provides you with a list of PROJECTS contained
within the spreadsheet and allows you to switch projects, or
to access an additional file under a project.
When a PROJECT is opened, The tree structure lists all of
the files contained in the project. The names of the files
are also listed in "tab" above the text_area. You can switch
between files by either clicking on the tree entry or the
"tab" name.
3. Revision History - provides you with a list of saved contents of
the project. You can back-off changes using this option.
4. Rename - This sub-menu allows you to change the name of a FILE
within a PROJECT, or the name of the PROJECT. The object
that is renamed is determined by the entry selected in
the "tree" in the left column.
5. Delete - This sub-menu allows you to delete either a FILE within
a PROJECT or the entire PROJECT. The object deleted is
determined by the high-lighted entry in the tree structure
in the left column.
6. Make A Copy - inserts a duplicate copy of the current file selected
in the tree structure, and switches access to the copied
file's contents. If the current entry in the tree structure
is the PROJECT entry, then this and other sub-functions
which do not apply at the PROJECT level are inactivated
(grayed out).
7. Save - Marks the current contents of the selected file as a
restore point, and saves its contents so that it is
accessible the next time the editor manipulates this project.
You can have unsaved changes in multiple files. This option
only saves changes to the currently active file.
8. Save All - This saves the contents of all files that have unsaved
changes. The editor places a "red star" in front of the
FILE's name in the "tab" for that file. As each file's
changes are saved. the "red star" is removed.
9. Manage Versions - This sub-menu allows you to assign a NEW version
number to a project. It really does not allow you
to manage the current version definitions. It prompts
you for a description (a reason for creating a new version).
By defining a "version" number you make the PROJECT usable
as a library.
10. Project Properties - This sub-menu provides access to a set of attributes
that are associated with the PROJECT object. I have not
explored the use of "User Properties" and "Project Properties"
tabs. I expect that they are concerned with saving Key-value
pairs (as global variables) across spreadsheet access sessions.
But I will explore them later.
The important attribute on the "INFO" tab (for me) is the
"Project Key" attribute. This is the value that you must
copy/paste into another spreadsheet file, in order to access
the functions contained in this PROJECT without having to
copy the actual function definitions into referencing
spreadsheet file.
11. Build a user interface - I have not explored this sub-menu.
Now once you have assigned a "version" number to a project, that project
can be used as a "reference" (i.e. LIBRARY) in another spreadsheet file.
Here is how you do this:
1. Go to the spreadsheet file that contains the PROJECT (i.e.LIBRARY)
that contains the PROJECT you want to "reference"
2. Access the "tools" menu to gain access to the project. Use either
the "Script Manager", or the "Script Editor" options. If your
spreadsheet only has one PRJOECT, then the "Script Editor" will
take you to that PROJECT. Otherwise, use the Script Manger, to
select the PROJECT. (If you open the Script Editor, and the spreadsheet
file has more than one PROJECT, it will prompt you to select which
PROJECT that you want to access.
3. Go to the "File/Project Properties" sub-menu within the editor and
select (high-light) the Project Key's attribute's value. and copy
it to your "clip board" (i.e. CTRL-c). You can then close this
spreadsheet file.
4. Open the spreadsheet file that contains the scripts that needs
to reference the functions from the other PROJECT(LIBRARY).
5. Access the PROJECT containing the functions that are to call
the external functions from the LIBRARY.
6. In the editor go to the "Resourses/Manger Libraries" sub-menu.
You will receive a panel with the title "INCLUDED LIBRARIES".
7. To add the new library reference, paste the copied Project Key
value into the "Find a Library" field, and press the "SELECT"
button.
8. If you have not made an error, you will set the list of libraries
updated to include your PROJECT added to the list.
Each row in the PROJECT (library) list contains 5 entries. Here
is how they are used.
1. Title - This contains the name of the PROJECT from the other
spreadsheet file. This is the name that is associated
with the "Prject Key". You can not change this value,
within this referencing file.
2. Version - This shows which version of the PROJECT resources that
you are allowed to access by this definition. The
drop-down list shows you which versions are available
and the comment you entered when you created the version.
3. Identifer - This shows you the qualifier that you are to use
within your FUNCTION definitions to uniquely identify
which function you are calling. You are allowed to
change this value even after you have initially defined
it. This identifier is similar to a "namespace" qualifier
that is found in an XML document. If you change the
qualifier value you must make a similar change to
all code within your functions that reference this
identifier, otherwise an error is thrown at execution
time (to the end user) that an undefined identifier has
been encountered.
4. Development Mode - This attribute impacts the execution of the
scripts in the current spreadsheet. It tells the spreadhseet
engine NOT TO SAVE the compiled image of the target
(referenced) library. This will slow down the execution
of your script since the spreadsheet engine will compile
your script every time you execute it, and it will also
recompile the contents of the LIBRARY each time. You should
only use "Development mode" when you are debugging a problem
with a library script.
5. Remove - when clicked removes the "Library definition" from the list
of included libraries.
Library definition changes are automatically saved when you close the
mangers access panel. At the bottom of the panel are two buttons.
"SAVE" - allows you to save changes and continue to make Library
definitions. CANCEL - causes the manger function to exit. Any
changes since the last SAVE are discarded.
To call a Library function in your script is similar to calling
the "msgBox" method of the "Browser" object. For example to
call the msgBox function you include "Browser.msgBox('...')"
clause.
To call the "doSomething" function in a library (project) for
which you assigned the "identifier" of "LETS", you would
code the clause "LETS.doSomthing(....)".
After discovering these "facts", I have come to the following
conclusions:
1. The purpose of the spreadsheet file should be to only hold the
LIBRARY function definitions.
2. If you are going to use a PROJECT as a LIBRARY, then you probably
will want to have multiple PROJECTs in the spreadsheet file that
contains the LIBRARY. The primary PROJECT should hold the
function definitions that make up the LIBRARY. A second project
should be defined that holds testing functions. Only the LIBRARY
project should be given a version number.
3. The spreadsheet data in general will not be available to the
scripts that references the LIBRARY. They can be made available
but not without opening the libraries spreadsheet file as a
separate application.
4. I don't know (since I have not tested this), but I assume that
the PROJECT PROPERTIES and USER PROPERTIES of the library (spreadsheet)
file are NOT accessible to the library functions when they are called.
I can see both, views which would allow and prohibit this access.
For security reasons I would guess that they would not be available.
(I could be wrong! - and generally I am).
5. I like the idea of using FILES. In fact, I plan to use one file
for each function. From a Object Oriented Programming perspective,
you will probably want to use a separate file for each Object's
definition. You must realize (at this time) the JavaScript language
does not support "Object Definitions". The use of FILES as a container
seems to be the reason for creating the FILE construct.
6. The FILE object also allows you to limit the scope of view and change
to functions within the FILE. In this way, you cannot corrupt other
functions which are not in the file.
7. I found a significant impact on execution time when a script is run
that references one or more Libraries. My guess is that execution
performance can be improved over time, with the use of JIT and caching
facilities.
8. From an end-user's perspective, it would be nice is a "clock" type
cursor icon would appear to the end user when a script is executing.
This is very important considering the time it takes to execute code
that references library functions.
9. For script execution performance reasons, you may anticipate that
you will have to make the library functions an actual part of your
spreadsheet file. Looking ahead to this possibility, I would
create dummy (skeleton) functions within my spreadsheet scripts
which do nothing more that pass the input parameters to the
library functions with the proper namespace identifier. Then
when I have to copy in the library functions I only have to
change the dummy functions. I would put these skeleton functions
into a separate file. I would use one file for each library
reference definition.
该团队刚刚发布了一项新功能：script libraries，请看看它是否符合您的要求。
编辑： 这是很容易的：选择一个电子表格，其中包含要添加到您的库的脚本，保存脚本的版本，将此版本添加到您的库和复制某处提供的密钥（此关键是也是用于管理您的图书馆的网址的一部分） 在另一个电子表格中，转至'管理图书馆'，添加密钥并保存。 从那里只需输入库名+ dot + CTRL SPACE（自动完成），就可以在新脚本中直接使用属于该库的所有功能。 希望这是足够清晰的。 看一个例子的屏幕截图：Caltosheet是库的名称，它有自动完成对字母C为好）
你的建议听起来很有趣。然而，这些文件缺乏足够的信息以用于任何用途。 “创建库”这个话题实际上并不能解释这个过程。它只谈“共享”。没有定义添加，更改，删除成员的过程。在电子表格或其他文档中引用单个脚本/函数的过程不被解释，除了如何“链接”（使可访问）。我很乐意使用它，但我无法知道如何从我已阅读的文档中执行此操作。 –
