lex:tldr:1ec37
This command is running the "lex" command with the argument "-t" and two variables (${analyzer-l} and ${analyzer-c}).
The lex command is a lexical analyzer or scanner generator. It takes as input a description of tokens or patterns and generates code for a lexical analyzer that can recognize and tokenize those patterns in an input text.
The argument "-t" is an option for the lex command which directs it to output the generated C code to the standard output instead of creating a C file.
The two variables (${analyzer-l} and ${analyzer-c}) are likely to be file paths or names that are provided as input to the lex command. The "> ${analyzer-c}" part redirects the standard output of the lex command to a file specified by the ${analyzer-c} variable.
In summary, this command is utilizing the lex tool to process a lexical analyzer description and generate C code, which is then redirected to a specific file.
