Syntax¶
A syntax of shellflow is very similar to bash script. Most important difference is annotating input files and output files with parentheses and brackets.
Input files¶
All input files should be enclosed with parentheses.
cat ((INPUT_FILE))
If some input files are not appeared in command line, it should be written in comment.
gcc ((hello.c)) # ((hello.h)) this command depends on hello.c and hello.h
When glob is used, all input files should be exists in advanced of shellflow runing.
Varaible¶
A varaible should be enclosed with curly brackets, when the variable is used in command line.
echo {{variable}}
To set value to variable, flowscript, embedded script language in
shellflow, or parameter file should be used. When a line starts with
#%, the line will be parsed as flowscript.
#% varaible = "foo"
Loop¶
for loop is supported in shellflow. do and done are required
in shellflow.
for x in a b c; do
echo {{x}} > {{x}}
done
Variable names should be enclosed with curly brackets.
When glob is used, all input files should be exists in advanced of shellflow runing.
if¶
if statement is not supported currently.
