    TMX editor

    TMX editor

    Open, edit .tmx files and set specific metadata

    Open, edit .tmx files and set metadata to make them of better use in the most CAT programs. Very light program written in C++, enables you to open (almost) any types of bilingual .tmx file, edit it, split and merge segments, shift the segments up and down as well as delete them. In-built QA checker helps to identify wrong alignments. The most important is the ability to add and edit metadata - proper ones as well as those embodied in opened tmx. Finally you can save the TMX in a well-structured form easily readable by most of the CAT tools. BEFORE the INSTALLATION, download LF_aligner_4.05_win.zip from https://sourceforge.net/projects/aligner/ and have it in the same directory as the installer of this program. Installer will unzip, combine and install these two programs. LF aligner is necessary as the alignment functions are based on its engine (thanks to Andras Farkas) The Help to the program is accessible on the wiki page http://sourceforge.net/p/tmxeditor/wiki/Home/

    RedDiamond

    RedDiamond

    Text editor supporting EDT keypad navigation

    This began as a fork of the Diamond text editor. It now shares very little DNA with Diamond because it uses CsScintilla edit widgets and has many more features. EDT keypad navigation, themes, configurable backup history, along with many other improvements have happened. Project still uses CopperSpice cross platform library. Linux users upgrading from older versions to 3.5.8 or later should cd .local/share rm -rf LogikalSolutions rm -rf LogikalSolutions-RedDiamond/ rm -rf ~/.config/LogikalSolutions-RedDiamond/ Due to database changes.
