Undocumented Komodo Command

I was trying to do something earlier, where instead of creating a Command, I just used a macro that executed a command, but I wasn’t really able to. Then, I happened to record a macro where, instead of having made the command earlier, I ran it while recording. The following JavaScript is the macro:

// Macro recorded on Sat Apr 14 2007 00:30:57 GMT+0930 (CST)
if (komodo.view) { komodo.view.setFocus() };
Run_RunEncodedCommand(window, ’python -u {'operateOnSelection': True}’);

Now, I just need to see if I can use python macros to get the same effect.

Komodo Macros

I’ve been working on a few little macros for Komodo. I’m planning to build a more cohesive set as I use the editor more.

Export HTML Tools.

The first is Copy As HTML Snippet. This gets an HTML representation of the current document and it’s syntax styling, and stores this in the Clipboard. There are two related tools: Export As HTML, and Export Selection as HTML. They save either the whole file, or the current selection. They create a new file, rather than store the data in the Clipboard. Each to her own. The code for each: (recursion: uses the macro to get the code of the macro…)

Copy As HTML Snippet.

 1 from komodo import components, document  
 2 from xpcom.server import UnwrapObject  
 3 import re  
 5 # Get the current buffer, and an html representation.  
 6 buf = UnwrapObject(document.ciBuf)  
 7 html = buf.to_html(False,False,None,True,True)  
 8 # Remove some debugging code left by the developers.  
 9 html = html.replace('onmouseover="show_class(event.target);"','')  
10 html = html.replace("'","'")  
11 html = re.sub('SCE_P_.*? ','',html)  
13 # Put it into the clipboard,  
14 ch = components.classes["@mozilla.org/widget/clipboardhelper;1"].getService(components.interfaces.nsIClipboardHelper)  
15 ch.copyString(html)

Export As HTML

1 import komodo  
2 komodo.view.setFocus()  
3 komodo.doCommand("cmd_exportHTML")

Export Selection As HTML

1 import komodo  
2 komodo.view.setFocus()  
3 komodo.doCommand("cmd_exportHTMLSelection")

You can get a Project (mutliple part packages are broken on export for me at the moment) with all three macros from: HTML Export Tools.

Java Development Tools

This will eventually, I hope, become a more useful set of tools, perhaps being replaced by better interaction with, for example, Komodo’s native debugger. At the moment, debugging requires knowledge of the specific debugging commands. However, I am confident I can use the inbuilt Breakpoint structure to create breakpoints easily, and step through code.

Build & Execute

This macro calls a Command, at the moment, after saving the file.

 1 import komodo  
 2 komodo.view.setFocus()  
 3 komodo.doCommand('cmd_save')  
 4 try:  
 5     komodo.findPart('command', 'Java Build & Execute', '*').invoke()  
 6 except:  
 7     from xpcom import components  
 8     wwatch = components.classes["@mozilla.org/embedcomp/window-watcher;1"].getService(components.interfaces.nsIWindowWatcher)  
 9     prompt = wwatch.getNewPrompter(wwatch.activeWindow)  
10     prompt.alert("Execution Error", "Unable to find 'Java Build & Execute'")  

Java Build & Execute

This is a Command, with the following in the Command: section if test “%F” -nt “%b.class”; then { javac “%F” ; if test “$?” == “0”; then java -classpath . “%b”; fi; } else java -classpath . “%b”; fi This should all be on the same line. In the Start in: box, insert %D

Java Build & Debug

Basically the same as the above, but with java replaced by jdb: if test “%F” -nt “%b.class”; then { javac “%F” ; if test “$?” == “0”; then jdb -classpath . “%b”; fi; } else jdb -classpath . “%b”; fi Start in: must be %D The project containing all of these can be found at Java Tools.

Python Tools

My python tools are a bit simple at this stage - after all, there’s already a fair bit of stuff in there to work with python! I do have a couple of bits that are useful. The Run Command… dialog is okay, but I always forget to save the document before running it, so I have two pairs of tools, one to Save and Run the file, and the other to Save and Run the file interactively. They are basically the same, with the difference of one command line switch, and the name of the command in the macro.

Save and Run Current Script

 1 import komodo  
 2 komodo.view.setFocus()  
 3 komodo.doCommand('cmd_save')  
 4 try:  
 5     komodo.findPart('command', 'Run Current Python File', '*').invoke()  
 6 except:  
 7     from xpcom import components  
 8     wwatch = components.classes["@mozilla.org/embedcomp/window-watcher;1"].getService(components.interfaces.nsIWindowWatcher)  
 9     prompt = wwatch.getNewPrompter(wwatch.activeWindow)  
10     prompt.alert("Execution Error", "Unable to find 'Run Current Python File'")  

I’ve put a nice icon on it, which you can get by right-clicking on the following image, and downloading it.

Run Current Python File

This is a fairly simple one, there’s really only one trick. python -u “%F” And %D in Start in:, as before. The -u tells the interpreter not to buffer input and output.

Save and Run Interactively/Run Current Python File Interactively

Just add the word Interactively in the two places in the macro, and add -i in just before the -u in the command. Simple!

Execute Selection

Another simple one, this is just a python -u command that has the Pass selection as input box checked.

Execute All

A simple macro that selects all before running the above command. I may try to improve it so it re-selects the initial selection after. Maybe. I just used the macro builder to create this one. Cmd-A, then click on the Execute Selection tool. As before, get all of them from Python Tools.

Komodo IDE Python Interactive Shell

The python interactive shell on Komodo is pretty cool. I’d like it to be a bit more responsive, but I can’t really put my finger on what’s going on. I did notice, with python 2.5 that it pops up this traceback on a Ctrl-D:

 1     Traceback (most recent call last):
 2       File "/Applications/Komodo IDE.app/Contents/SharedSupport/dbgp/bin/pydbgp", line 270, in <module>

Komodo Bugs

I’ve already filed, and had one of these fixed, but that’s only in the next beta, so I’ll write about it here, too. If you double-click an associated file in Komodo 4.0.3 that isn’t one of the standard files, like a .java source code, for example, and Komodo isn’t running, it will not start properly. Double-clicking it when Komodo is running loads it normally. If you have a wide text load in a clipboard, and copy it into a buffer, sometimes the buffer scrollbar doesn’t go all of the way. I’ll do some more testing on this tonight, but it was a bit of an annoyance. Kind of hard to explain - I need to take some screenshots, or perhaps even make a screencast.

Komodo 4.1 Paste Bug

I have discovered a bug in Komodo IDE, version 4.1.0-beta1, build 276433, platform macosx-powerpc; Built on Fri Mar 2 17:20:02 2007. If you fill the clipboard with text that is wider than the buffer, which defaults to being 250 characters wide, and paste this into a new document, then the scrollbar down the bottom does not reflect the new width. Thus, if you drag the scrollbar across to the right, you do not see all of the inserted text. If you click on the scrollbar arrow, then you can still move further to the right, as if you drag-select in the editing frame. This bug does not always appear in Windows, which moves the cursor to the end of the inserted text. However, if multi-line text is pasted, then the bug displays itself. Hopefully, the images below make this clearer. I did try to record a screencast, but the quality was crap, and the filesize was huge… Clicking on the images will open them in a new window. You can see enough detail without doing this, if you know what to look for. Image 1 shows the HTML document before I paste in the long lines of text. Image 2 shows how the Scroll Bar width has not changed. Image 3 shows how the full text is not visible if the thumb is fully dragged to the right. Image 4 shows how drag-selecting the text changes the size of the thumb.
