There are a few special conditions we use: <code>! Dir/LR</code>, <code>! Dir/RL</code>, and <code>! Use/MT</code>.

Otherwise lexc simply interprets these as comments. |

For Apertium, we use the lexc for certain transducers. There are some apertium-specific conventions we employ, outlined below. This wiki also has a comparison of lttoolbox and lexc formats.
Preferred format for stem definitions[edit]
The preferred format for stem definitions is underlying:surface CLASS ; ! "gloss", with optional following conditions, for example:
бул:бу DET-DEM ; ! "this" ! Dir/LR
Morpheme boundary[edit]
We use %> as a morpheme boundary indicator in lexc.
Conditions[edit]
There are a few special conditions we use: ! Dir/LR, ! Dir/RL, and ! Use/MT. These allow us to grep out lines to have different right-to-left and left-to-right transducers, and also have separate MT-specific and vanilla transducers. Otherwise lexc simply interprets these as comments.
We also use the comment ! TOCHECK to indicate that a stem needs to be verified for accuracy, spelling, classification, etc.
Bracketed multi-character symbols[edit]
We define certain types of multi-character symbols for various purposes.
Tags[edit]
Tags are defined with less-than and greater-than signs, e.g. %<pl%>.
Archiphonemes[edit]
Archiphonemes are defined with curly braces, e.g. %{A%}.
Features[edit]
Features are defined with square brackets, e.g. %[%-coop%].
Syntax highlighting and folding in vim[edit]
If you want to have lexc syntax highlighting and/or folding in vim, you can get latest version of lexc vim plugin at this github address. Feel free to fork, add features, and submit pull requests :)
Some other options are listed on the vim page.
