The duplicate file finder freeware is generally not as good as the paid counterpart in terms of capacities and performance, but sometimes they are already useful enough. Some of the apps on our list of the best free duplicate file finder software are freeware. Some also have paid editions which have more advanced features. There are also a few decent open-source apps. However, they haven't been updated for years. Therefore, they are not included in this list.
Each of these txs-command has a unique id, which is shown as tooltip of the displayed name for "normal" commands and in the edit box for user commands. Some important commands are usual: txs:///quick (Build & View, the old quickbuild), txs:///compile (Default compiler), txs:///view (Default viewer), txs:///latex (latex), txs:///pdflatex (pdflatex), txs:///view-pdf (Default Pdf Viewer), txs:///view-pdf-external (External pdf viewer).For example, in a typical build configuration you might call txs:///quick by pressing F1, which calls txs:///compile, which first calls txs:///pdflatex that calls the actual pdflatey, and then calls txs:///view, which calls txs:///view-pdf, which calls txs:///view-pdf-internal, which displays the pdf.There is no difference between commands defined as command on the command config page, commands defined as build on the build config page, or commands defined as user commands. They are just separated in the GUI to simplify the interface.This also means that you can change every command as you want, ignoring its old definition (you could even change its id, when editing the ini file.).There are however three always defined internal commands, which can only be called and not modified:txs:///internal-pdf-viewerOpens the internal viewer for the current documenttxs:///view-logViews the log file for the current documenttxs:///conditionally-recompile-bibliographyChecks if the bib files have been modified, and calls txs:///recompile-bibliography, iff that is the caseThe internal pdf viewer also accepts the following options (txs:///internal-pdf-viewer) to modify its behaviour:--embeddedOpens the viewer embedded--windowedOpens the viewer windowed (default if no option is given)--close-(allwindowedembedded)Close all open viewers, or just viewers of a specific kind--preserve-existingDoes not change any existing viewers (i.e. always opens a new one)--preserve-(embeddedwindowed)Does not change any existing embedded/windowed viewers--preserve-duplicatesOnly opens the pdf in the first opened viewer--(no-)auto-closeDetermines whether the viewer should be closed, when the corresponding tex file is closed (default: auto-close iff embedded)--(no-)focusDetermines whether the viewer should be focused (default: focus iff windowed)--(no-)foregroundDetermines whether the viewer should be brought to front (default: foreground)filenameDetermines the file to open. Like in other commands, file patterns are supported. If this parameter is not provided, TXS uses "?am.pdf", i.e. the absolute path of the main file. If the parameter is not an absolute filename, it is searched for in the directory of the main file as well as in Options -> Build -> Build Options -> Additional Search Paths -> PDF FilesIt is also possible to modify the arguments of called subcommands with argument modifiers or by adding a new argument . These modifiers are passed through called lists, so it will always change the arguments of the finally called program, even if the directly called subcommand is just a wrapper around another command:txs:///foobar --xyzThis will add the xyz optiontxs:///foobar[--xyz=123]This will change the value of the xyz option to 123 (i.e. removing any xyz option defined in foobar)txs:///foobar--xyz=123This will remove --xyz=123 from the foobar command line, ignoring xyz options with other valuestxs:///foobar--xyzThis will remove any --xyz option from the foobar command line, regardless of its valuetxs:///foobarThis will remove all options from the foobar command line, leaving only the name of the executableFinally, there are also hidden options, which can only be changed by modifying the ini-file: Tools/Kind/LaTeX, Tools/Kind/Rerunnable, Tools/Kind/Pdf, Tools/Kind/Stdout, Tools/Kind/Viewer, which give a list of commands that are treated as latex compiler (e.g. show the log afterwards), rerunnable (repeat command call, if there are warnings), pdf generators (e.g. pdflatex), commands that prints to stdout (e.g. bibtex), and viewers (e.g. only open once). 2ff7e9595c
