Gexync is a GEX ini file editor. |
||||
The editor loads the INI file through the communication interface |
||||
without having to mount the virtual filesystem, which is unreliable |
||||
on some systems. |
||||
|
||||
This utility allows live editing of the UNITS.INI file. |
||||
|
||||
On save, a new version is loaded with formatting and error messages |
||||
generated by GEX, as if the virtual config filesystem was re-mounted. |
||||
|
||||
The editor does not keep GEX claimed, instead does so only when needed. |
||||
This allows testing of the current configuration without having to close |
||||
and reopen the editor. |
