Change color of text after the echo in batch

amymor

I know I can use REM or :: to comment but comments are not visible during batch execution. I want to use echo for commenting as well as printing. Is there a way to specify a custom color for a line that starts with echo?

I had some luck using the EnhanceAnyLexer plugin.

Have a batch file be the active file in Notepad++ and then invoke the plugin’s menu option Enhance Current Language. An .ini file for the plugin will be opened in Notepad++ and some options specific to a batch file will be added to it. You can then configure it like this:

Note that I didn’t show the entire “excluded_styles” line because I didn’t change that line anyway.

Here was the effect in a batch file:

@Alan-Kilborn After installing the EnhanceAnyLexer plugin, npp won’t open. Is there a another way to do it?

@amymor

There’s often more than one way to do things. But EnhanceAnyLexer is arguably the easiest solution to your problem.

If I were you, I’d attack the “npp won’t open” problem.
Without more info from you about that, though, we can’t offer up much help.

@Alan-Kilborn I don’t know more because it doesn’t give me any error

Suggest: Remove the plugin by renaming its DLL file to a new name (any name will suffice). Attempt starting of Notepad++. Does it start?

amymor

@Alan-Kilborn yes

I tried an old version of it (version 0.1.0 first beta) and then it worked

@amymor

OK, well that certainly points to a definite problem. In my experience the plugin works fine. Perhaps the plugin’s author @Ekopalypse who is active here, can assist.

I noticed that the last two versions of it don’t work for me, but the v.0.5.0 beta and previous versions work.

@amymor said in Change color of text after the echo in batch:

Npp 8.4.2.0 x64

Ah, OK, v1.01 of EnhanceAnyLexer also causes N++ 8.4.2 to not start up when I tried it as a test. N++ 8.4.3 and 8.4.4 start up fine with it.

The reason for the problems may be changes with the interface. Obviously N++ and plugins have to cooperate, and if N++ undergoes a change in core logic that make plugins incompatible, plugins have to evolve.

I suppose your options are to continue with the EAL 0.5.0 beta or update your N++ and use the newer EAL, if you want to continue with this.

@Alan-Kilborn Thanks for your response, I will update the npp.

I suppose that I have found the cause of the problem
It looks like calling NPPM_GETLANGUAGENAME with a value of -1 can cause npp to crash. I assume this also applies to NPPM_GETLANGUAGEDESC, as I suspect the problem manifests itself when getLangDesc is called.

I add a check in EnhanceAnyLexer to prevent calling it in this case

pub fn(n Npp) get_language_name(buffer_id usize) string {
	lang_type := n.call(nppm_getbufferlangtype, buffer_id, isize(0))
	if lang_type == -1 {
		return 'UNKNOWN_ERROR'
	}
	mut buffer_size := int(n.call(nppm_getlanguagename, usize(lang_type), isize(0))) + 1
	mut buffer := alloc_wide(buffer_size)

	n.call(nppm_getlanguagename, usize(lang_type), isize(buffer))
	lang_name := unsafe { string_from_wide(buffer) }
	return lang_name.to_lower().replace('udf - ', '')
}
