Perhaps you should read the documentation for "emacs, vi, ultraedit."	[reply]

Komodo got it from Emacs, its called flymake-mode see emacs wiki or sourceforge But be aware of downsides: Vulnerabilities when editing untrusted code... (Komodo)! searching for "flymake YourEditor" will show you more alternatives. Cheers Rolf	[reply]

Thanks for the head up ... I use Komodo!	[reply]

Hi astroboy, I'm not a Komodo expert, but it's likely that they also copied the configuration options emacs offers. from `Customize Group: Flymake` `Flymake Start Syntax Check On Find File: Toggle off (nil) State: SAVED and set. Start syntax check on find file.` No check on load means that simply viewing a foreign file w/o modifying it won't be a risk. ("Find file" is emacs lingo for loading a fileš for editing) HTH! =) Cheers Rolf š) or switching to a file if already loaded	[reply] [d/l]

When syntax coloring is turned on, vim will (on my system, at least) flag invalid syntax with white text on a red background. OTOH, your example isn't what I would call a syntax error. By misspelling the variable name ($namw) in the second line, the third line appears to use an undeclared variable, which vim won't catch.	[reply]

The OP means automatically running `perl -c` on the current file in the background to display compile time errors "on the fly". Syntax errors are only a subset of possible compile time problems, like missing modules. This way warnings and fatals are found an external highlighter would never notice. How flymake works When flymake mode is active, any of the 3 conditions stated above will cause flymake to try to syntax check the current buffer. Flymake first determines whether it is able to do syntax check. It then saves a copy of the buffer in a temporary file in the buffer's directory (or in the system temp directory -- for java files), creates a syntax check command and launches a process with this command. The output is parsed using known error message patterns, and error information (file name, line number, type and text) is saved. After the process has finished, flymake highlights erroneous lines in the buffer using the accumulated error information. There are ports for other editors, e.g. https://github.com/kana/vim-flymake Cheers Rolf	[reply] [d/l]

EPIC, a Perl Editor and IDE for Eclipse, supports on-the-fly syntax checking. There are Windows, Linux and Mac OS X versions.	[reply]

Default emacs installation on debian/wheezy, just open your file in emacs and hit `M-x flymake-mode`. This mode has only two useful functions which you may want to assign to some keys like `(global-set-key [f5] 'flymake-goto-next-error) (global-set-key [f6] 'flymake-display-err-menu-for-current-line)` [download] ...in your .emacs.d/init.el file. For even more fun run `M-x cperl-mode` and read it's docs with `C-h m`.	[reply] [d/l] [select]

For even more fun :) `M-x customize-mode [RET] Major mode: flymake-mode [RET]` [download] (or click Options -> Customize Emacs -> Specific Group) And you're getting an interactive menu to change settings. For instance I've changed the error highlighting to underlining and switched off the option to flymake on file-load (security reasons). Cheers Rolf	[reply] [d/l]
