Errors trying to create language extension

[Mysterial]

Komodo 9.2/Win7 x64

When I try to use the language extension template, after filling out the form I get these errors:

[Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [koIFileEx.open]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: chrome://koextgen/content/koextgen_lib.js :: this.writeFile :: line 125" data: no]

arg filename: G:\Komodo\LScript\components\koLScript_UDL_Language.py

I checked the directory where I put the project and there's only a ".komodotools" directory and the project file, it doesn't appear to have written the source files. I tried different paths as well as filling only the minimal amount in the form in case something I was adding was breaking it, but that didn't seem to help.

[Mysterial]

I confirmed that this works correctly on 9.1

[Naatan]

Cannot reproduce. Can you provide the exact steps, including what you filled out in the wizard?

[Mysterial]

I opened it via Project -> New From Template -> Create Komodo Language

To test, I left all the fields at default except for language name (LScript) and file extension (.ls)

[Naatan]

Are you certain you had write permissions to the location where you chose to save the files?

[ervumlens]

I think I'm seeing the same thing (KE 9.2.0, Vista 32 bit), using c:\projects\LScript as the project folder, then following Mysterial's steps by leaving the defaults except for language name and extension.

The path is writable and not special in any way. The LScript.komodoproject file, .komodotools folder, and the folder's contents are there, but nothing else (same as above).

Could the extraneous double quotes in the filenames be causing a problem? shrug

Here's the log:

I see the same errors after creating a regular extension, too. (KE 9.2.0, Vista 32bit)

[Naatan]

@mitchell-as could you please look into this for 9.2.1? I think it might be windows only.

@ervumlens - woah, vista? Living life on the edge huh :p

[mitchell-as]

@Naatan I confirm this is a bug and was introduced in 9.2. It works just fine in 9.1. I don't know what might have caused it though.

[ervumlens]

Floating quotes in the path produces the error.

• ko.interpolate.interpolateString('%p') is producing the double-quoted project folder names in Windows as of 350f53a.
• The project name is not joining correctly to the file name in koextgen_lib.getProjectPath(...).
• This leads to a failure to copy the files in koextgen_lib.updateProject(...).

I'll test this some more in Windows 6 once the hard drive light stops flashing for no reason.

[ervumlens]

Here's a macro that shows the problem a little clearer. First create a file named testfile.js in the project and save it with something in it, then run the macro.

//This is a javascript macro
var koext = ko.koextgen.extensionLib;
var filename = koext.getProjectPath('testfile.js');
alert("filename: " + filename);
alert("contents: " + koext.readFile(filename));

In Windows, In KE 9.1, the contents are displayed correctly. In 9.2, the contents fail to display.

[Naatan]

Awesome job tracking that down @ervumlens, that will make fixing this a ton easier.
