tmp
)Create a temporary file and write to it
tmp
creates a temporary file, writes the contents of stdin to it then returns its filename to stdout.
You can optionally specify a file extension, for example if the temporary file needs to be read by open
or an editor which uses extensions to define syntax highlighting.
<stdin> -> tmp [ file-extension ] -> <stdout>
» out "Hello, world!" -> set tmp
» out $tmp

Hello, world!
The temporary file name is a base64 encoded md5 hash of the time plus Murex function ID with Murex process ID appended:
package io
import (
"crypto/md5"
"encoding/hex"
"io"
"os"
"strconv"
"time"
"github.com/lmorg/murex/lang"
"github.com/lmorg/murex/lang/types"
"github.com/lmorg/murex/utils/consts"
)
func init() {
"tmp", cmdTempFile, types.Any, types.String)
lang.DefineMethod(
}
func cmdTempFile(p *lang.Process) error {
p.Stdout.SetDataType(types.String)
0)
ext, _ := p.Parameters.String(if ext != "" {
"." + ext
ext =
}
":" + strconv.Itoa(int(p.Id))
fileId := time.Now().String() +
h := md5.New()byte(fileId))
_, err := h.Write([]if err != nil {
return err
}
nil)) + "-" + strconv.Itoa(os.Getpid()) + ext
name := consts.TempDir + hex.EncodeToString(h.Sum(
file, err := os.Create(name)if err != nil {
return err
}
defer file.Close()
_, err = io.Copy(file, p.Stdin)if err != nil {
return err
}
byte(name))
_, err = p.Stdout.Write([]return err
}
This should should provide enough distance to run tmp
in parallel….should you ever want to.
tmp
files are also located inside a unique per-process Murex temp directory which itself is located in the appropriate temp directory for the host OS (eg $TMPDIR
on macOS).
