Java CI Latest version Downloads

A plugin that adds support for StringTemplate v4 to IntelliJ-based IDEs (version 15.x and later).

It understands .stg and .st files. For example,

See the plugin page for more information.

Highlighting the target language

You can configure Template Data Languages to make the editor highlight the content around StringTemplate tags. For example, if your template is used to generate Java code, you can go to File | Settings | Languages & Frameworks | Template Data Languages and configure which language to highlight:

The editor will now highlight Java parts around ST tags:

jetbrains-plugin-st4's Issues

Syntax highlighter breaks down on XML namespaces: mismatched input '=' expecting LPAREN

As the below screenshot shows, I get a bunch of errors on string template group files with XML. Most of these seem related to using XML namespaces, where the error shows mismatched input '=' expecting LPAREN on encountering something like s:mustUnderstand.

This example, using § for variables (§messageId§) is sufficient to display the error:

saml.stg

SamlAssertionRequest(messageId, to, createdAt, expiresAt, accessToken, target) ::= <<
<s:Envelope xmlns:s="http://www.w3.org/2003/05/soap-envelope" xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:u="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd">

Also seen that syntax highlighting breaks down on simple HTML too:

To be honest, I am not totally sure what this plugin is supposed to apart from some syntax highlighting, but it works pretty well (i.e. no errors) on JSON.

Marked the files manually using the correct filetype:

String template plugin in Rider (2022.3.1) fails to open template file (infinite spinning wheel)

Rider 2022.3.1 with Stringtemplate 0.9 and antlr 1.9.3-3 plugins installed.

Opening any string template file never succeeds, and just have an infinite (for my level of patience anyway) spinning wheel.

Using Intellij the same template files are opened with correct syntax highlighting etc.

The following error gets reported in the Rider idea.log after opening a string template file.

Include antlr4 commands used in README

Wanted to give the colorization work a quick look, tried opening the project as-is and got stuck on antlr/grammars-v4#274. This leads me to think I'm doing something wrong. Without a doubt it's been a long time since I worked with ANTLR and what little skill I had then is long-gone now...

Maybe including the correct incantations in the README.MD would make things go more smoothly?

NullPointerException after update to 0.9

Word Autocompletion

Add autocompletion (Ctrl-Space) for the following things:

  • attributes, templates and functions: given foo(bar) ::= << ... >>, < Ctrl-Space → foo(), bar, first(), length(), etc.
  • options: <foo; for Ctrl-Space → format; <foo; Ctrl-Space → separator, format, null, etc. Maybe it could also insert the trailing =
  • other reserved words in their respective contexts

Double-click word selection is broken

When double-clicking within a template to select a word, only a single letter is selected instead. This happens only for verbatim text, not for keywords or insertions.

Here's a recording, with the following steps:

  1. Press Alt-Shift-Left to select the verbatim word (works as intended).
  2. Double-click with the intention to select the verbatim word, but it only selects one letter.
  3. Double-click to select the word within the attribute insertion (works as intended).
  4. Double-click to select the keyword if (also works as intended).

It's not in the recording, but double-click also works for template and attribute names. So the problem seems to occur only in verbatim text.

incompatible to IntelliJ 2018

Installation of ST4 plugin fails on IntelliJ 2018 versions.
Error messages suggest it needs a different packaging (?).
Reported to IntelliJ, got delegated here. They consider disabling the plugin (if not fixed).

Code Folding

It would be really useful if one could fold template bodies in .stg files. See attached screenshot for an example, using IntelliJs custom folding regions (which unfortunately don't work very well when the code changes):

Antlr-based PSI?

Hi, I'd like to ask whether it is possible to somehow generate PSI classes from the antlr grammar, as PSI is needed to provide some advanced features such as code completion, etc. Or would that require rewriting the grammar into BNF/Flex?

Error markers have no tooltip

Most (all?) errors are highlighted, but have no tooltip that gives further information about the problem. See attached screenshot (hovering the mouse over the red text does nothing).

Show templates in symbol search

In Jetbrains IDEs, it is possible to search for symbols (like fields, methods, ...) either by using "Search Everywhere" or selecting the symbol search tab:

Being able to find templates in stg files this way would greatly improve navigation.

Incorrect highlighting inside strings

I've defined a map inside one of my templates:

typeMap ::= [
  "list<int>": "std::vector<int>",
  "list<long>": "std::vector<long>",
  "list<float>": "std::vector<float>",
  "list<double>": "std::vector<double>"
]

In the above code, <int>, <long>, ... are highlighted like attribute references.

Tab-to-indent does not respect indentation settings

I'm in an environment where the tab size is set to 3 (via an .editorconfig file, but not sure if that matters). When pressing Tab to indent a line within a template, it always indents by 4 spaces. Interestingly, when pressing Shift-Tab to de-indent, it removes 3 spaces. The correct behaviour would be that Tab indents by 3 spaces as well.

Support `.st` files

Support .st file highlighting - I'm using Intellij and st4 to generate HTML and this would be awesome.

I'm willing to help, just not sure where to start with Intellij plugins. Any insight as to where to start would be helpful, too.

Setting custom delimiters doesn't work with new highlighting

Previously for group files it was possible to declare custom delimiters and the highlighter acted accordingly.

delimiters "%", "%"

base(a, b) ::= <<
<root>
  <first>%a%</first>
  <second>%b%</second>
</root>
>>

Now it always highlights only < and >

Looking at the old code, this was removed:

jetbrains-plugin-st4/src/main/java/org/antlr/jetbrains/st4plugin/highlight/STGroupSyntaxHighlighter.java

Lines 71 to 75 in 5740453

final Collection<ParseTree> delimiterStrings = XPath.findAll(tree, "//delimiters/STRING", parser);
int i = 0;
for (ParseTree s : delimiterStrings) {
delimiters[i++] = s.getText().charAt(1);
}

jetbrains-plugin-st4/src/main/java/org/antlr/jetbrains/st4plugin/highlight/STSyntaxHighlighter.java

Lines 44 to 48 in 0c2abe1

@Override
public Lexer getLexer(String text) {
STLexer lexer = new STLexer(new ANTLR3StringStream(text), templateToken, groupHighlighter.delimiters[0], groupHighlighter.delimiters[1]);
return lexer;
}

Highlight missing <endif>

Since there is no completion (#20) yet, it is easy to miss an <endif>. As such, it would be very useful if this fact were highlighted with an error indicator.

At runtime, this problem is reported as premature EOF at a seemingly random line in the file, which is very hard to figure out.

Color settings page

Allow the syntax highlighting colors to be configured with a settings page.

Project should is not ready for checkout

It should be way to clone and build project somehow but now it is just dead. I even can't generate parser by antlr4 tool

so I was expecting the following flow

  1. clone
  2. generate parsers, aka './generate.sh`
  3. open project, select IDEA SDK
  4. Chose run configuration and run

Colors unusable in Dracula scheme

I am using dark Idea scheme Dracula and when I open the stg file, the colors are very bad because the default white palette is expected. It prevents the plugin to be usable.

The colors should take existing scheme or be configurable.

Auto-closing paired symbols

When typing new templates, it would be very useful if certain opening/closing constructs were autocompleted. This applies to:

  • the closing parenthesis after the argument list: foo( )
  • the template delimiters: << >>, <% %>, " "
  • placeholders < > (also for custom delimiters?)
  • ifs: <if( )> <endif>
  • anonymous templates: <foo:{ }>
  • ...?

Seems to make Java code yellow in 15.x

14 is ok but intellij 15.0.1 has all it's java code turn yellow but template names as black. template names should be yellow and it shouldn't touch java code.

Java can't find .stg files in IntelliJ

I'm using IntelliJ 15, ANTLR4, ST4 on Windows 7. PrettyPrint.stg is in the same directory as TestMain.java.

When I moved everything to Cloud9 it worked fine.
