Calling Java function with arguments from StringTemplate?

由 你离开我真会死。 提交于 2019-12-12 14:46:26
问题 StringTemplate allows programmers to fetch data through getters(a function with no arguments). I would like to know that Is it possible to call Java function with arguments from String Template? 回答1: There is a workaround by abusing dictionaries. Here is an example of implementing "function" for limiting item count in a List (issue on github). In your code add dictionary: group.defineDictionary("max", new MaxListItemsLimiter()); Usage (in this example first item in array is max. items count):

How to get StringTemplate V4 to ignore < as delimiter?

由 ☆樱花仙子☆ 提交于 2019-12-12 11:32:12
问题 I'm using StringTemplate V4 to generate some HTML code in my project. I need to have HTML formatting in my templates, so using the default delimiters < and > would be very awkward. So, I'm creating a group passing the delimiter as argument (as recommended by this question), but it simply doesn't work. Here is my test code: public void testTemplate() { char sep = '$'; STGroup stGroup = new STGroupString("temp", "<html>hello, $name$!</html>", sep, sep); System.out.println("Group created"); ST

StringTemplate invalid character '<' when reading XML Template

Any tutorials on setting up a templating framework on GAE (Java)?

由 北慕城南 提交于 2019-12-11 20:13:02
问题 I'm trying to format our emails by using HTML-formatted templates on Google App Engine (using Java), but for the life of me I cannot find a decent tutorial for how to set this up. I've tried looking at StringTemplate, but I cannot find any examples where a stand-alone template is loaded from a servlet's context and used as a formatter. Can anyone help? I'm open to any suggestions, such as Velocity or FreeMarker, so long as they run on GAE. Thanks 回答1: Figured out how to do it. The

ANTLR and Xtext integration for developing plugin

由 ↘锁芯ラ 提交于 2019-12-11 00:18:43
问题 My current project is focusing on code generation from High-level specification. More specifically, developers write high-level specifications and compiler parses them and generates Java code. For parser, I have used ANTLR grammar and for code generation I have used StringTemplateFiles. For providing nice editor support (with syntax high lighting & coloring), I have used xText. Now, the real problem comes - how can I integrate xText editor support with ANTLR parser and code generator? I want

问题 I would like to know how to create a custom format function for string template.

NoIndentWriter not respecting whitespace in template

由 守給你的承諾、 提交于 2019-12-10 08:48:54
问题 I am trying to use the NoIndentWriter class to get around a problem I am facing related to the inserting of whitespace in multiline Strings. However, it appears that NoIndentWriter does a lot more than just not auto-indenting. In particular it trims all leading (but not trailing whitespace) even if explicitly present in a template. E.g. with the following template file: $ cat src/templates/a.xml.stg ladder(value)::=<< 0 1 2 3 ^value^ >> ... and the following code: public static void main

embed java code inside a template

问题 Is it possible to embed executable java code inside a ST4 template? eg if I want to pass a string to my template, which sometimes prints the string as-is, and sometimes prints it in caps, so I want a java code to do the necessary conversion. Without this feature, I see 3 ways to achieve the same functionality: (1) pre-compute the alternative values in java, and pass them all to the template at one shot (but this may result in too many arguments): // in the below code, if the template can
